SSW-110-06-T-S

FAQFrequently Asked Questions

• What are the key design considerations when choosing the SSW-110-06-T-S for board-to-board interconnect versus cable-to-board applications? The SSW-110-06-T-S is configured as a receptacle connector with forked contacts and push-pull fastening, making it suitable for both board-to-board and cable-to-board configurations. However, board-to-board applications benefit from the 0.100" (2.54mm) pitch and through-hole mounting, which provide mechanical stability and repeatability. For cable-to-board use, ensure the mating connector (typically a pin header or similar) has compatible contact geometry. The push-pull mechanism requires adequate PCB space for engagement/disengagement, so verify clearance in your layout. If your application requires frequent mating cycles, the SSW-110-06-T-S forked contact design distributes wear more evenly than single-contact designs.
• Can the SSW-110-06-T-S safely handle the current and voltage requirements of my 5V and 3.3V digital signal distribution system? The SSW-110-06-T-S is rated for 4.7A per contact, which accommodates moderate power distribution and digital signaling. For 5V and 3.3V logic applications, this current capacity is typically sufficient for signal lines and moderate current-draw branches. However, the SSW-110-06-T-S does not have an explicitly specified voltage rating in its datasheet. For safety-critical or high-voltage applications, cross-reference the LCP insulation material's dielectric strength (typically 15–20 kV/mm for LCP) and verify that your operating voltage, including transients and overshoot, remains within safe margins. If distributing high current (>2A per line), consider thermal management and verify that solder joint resistance does not contribute excessive voltage drop.
• How does the tin plating on the SSW-110-06-T-S contacts affect long-term reliability in industrial environments with temperature cycling between -55°C and 105°C? The SSW-110-06-T-S uses tin plating on both mating and post contacts, which provides good corrosion resistance and solderability. Tin's melting point (~232°C) is well above the SSW-110-06-T-S operating range (-55°C to 105°C), so thermal cycling within spec does not cause plating degradation. However, tin exhibits tin whisker growth at room temperature over extended periods, particularly in high-stress environments or with RoHS-compliant pure tin. The SSW-110-06-T-S LCP insulation material resists moisture absorption better than phenolic alternatives, reducing electrochemical corrosion risk in humid industrial settings. For applications requiring 10+ years of outdoor or cycling operation, consider conformal coating or periodic inspection to mitigate whisker formation, and verify that connector contact forces remain adequate after thermal cycling.
• What is the impact of the 0.335" (8.51mm) insulation height on my PCB layout, and can the SSW-110-06-T-S be used in space-constrained applications? The SSW-110-06-T-S insulation height of 0.335" (8.51mm) measured from the PCB surface to the top of the connector body dictates minimum clearance for mating connectors, cables, or adjacent components. In stacked or multi-board designs, this height may constrain board separation or require custom spacers. For tight vertical clearance, the SSW-110-06-T-S is less suitable than lower-profile alternatives (such as 0.100" pitch surface-mount connectors). However, for distributed I/O or single-row signal distribution where vertical space is less critical, the 0.335" height is manageable. Verify that your housing or enclosure allows this profile, and ensure that the push-pull fastening mechanism has adequate access for unmating without flexing adjacent boards or components.
• Is the SSW-110-06-T-S compatible with standard 0.100" pitch headers and male pin connectors from other manufacturers? The SSW-110-06-T-S 0.100" (2.54mm) pitch receptacle is compatible with standard single-row male headers and pin connectors conforming to the 0.100" pitch specification, such as common products from Amphenol, TE Connectivity, Molex, and equivalent suppliers. The forked contact design of the SSW-110-06-T-S provides dual contact points, which may offer improved retention and lower contact resistance compared to single-post designs. However, compatibility depends on matching the mating connector's contact geometry, force, and insertion depth. Before selecting an alternative mating connector, measure its pin diameter and contact insertion depth to ensure they fall within the SSW-110-06-T-S forked contact's acceptance range (typically ±0.010" tolerance). Mismatched contact geometry can result in poor mating force, intermittent connections, or premature contact wear.
• What are the soldering and thermal management considerations when attaching the SSW-110-06-T-S post contacts to a PCB with a reflow or wave solder process? The SSW-110-06-T-S features tin-plated through-hole posts designed for solder termination, compatible with both wave and reflow soldering. The LCP insulation material has a UL94 V-0 flammability rating, indicating good thermal stability during soldering. For reflow, peak temperature should not exceed 245°C (per IPC-A-610 standards), and the SSW-110-06-T-S insulation maintains its mechanical properties within this range. The 0.124" (3.15mm) post length allows adequate solder fillet formation without bridging to adjacent pads. If using wave solder, ensure the dwell time does not exceed 4 seconds at peak temperature to minimize thermal stress on the LCP housing. Post-solder thermal cycling can induce mechanical stress at the solder joint, particularly in high-vibration applications; use solder alloys with appropriate creep resistance (SAC305 recommended) to minimize joint degradation.
• Can the SSW-110-06-T-S be used as a drop-in replacement for older 0.100" pitch connectors with different contact finishes or insulation materials? The SSW-110-06-T-S is a modern design with LCP insulation and tin plating, which are RoHS3 compliant and offer better moisture resistance than legacy phenolic or FR-4 housings. If replacing an older connector from the same series (such as the base SSW-110 with different plating or material), the SSW-110-06-T-S maintains the same 0.100" pitch and mounting footprint, making it mechanically compatible. However, differences in contact finish (e.g., gold vs. tin) can affect mating force, contact resistance, and long-term reliability. Gold-plated legacy connectors may exhibit tarnishing resistance superior to tin over decades, but tin's lower cost and adequate performance for most applications justify the SSW-110-06-T-S choice. Verify that the mating connector contact force aligns with the SSW-110-06-T-S forked contact design (typically 75–150 grams per contact) to ensure reliable mating after replacement.
• How does the push-pull fastening mechanism of the SSW-110-06-T-S affect mating reliability and cycle life in vibration-prone or shock-sensitive environments? The push-pull fastening mechanism on the SSW-110-06-T-S provides positive engagement and disengagement without tools, reducing accidental disconnection risk in vibration environments compared to friction-fit designs. The forked contact geometry combined with the push-pull system distributes lateral stress more evenly across multiple contact points, extending mechanical cycle life. In applications experiencing frequent vibration or shock (e.g., industrial machinery, transportation), the SSW-110-06-T-S demonstrates improved retention compared to simple press-fit connectors. However, the push-pull mechanism relies on plastic latching features molded into the LCP insulation. After extended vibration exposure (typically >10,000 cycles) or thermal cycling, these latches may experience stress relaxation, reducing engagement tension. For mission-critical applications, periodically inspect latch condition and consider supplemental mechanical retention (such as cable ties or retention clips) if mating cycles exceed design expectations.
• What is the contact resistance of the SSW-110-06-T-S, and how does it compare to alternatives when used in high-speed digital or precision analog signal paths? The SSW-110-06-T-S does not specify contact resistance in its datasheet. Typical contact resistance for tin-plated phosphor bronze forked connectors at this pitch ranges from 5–20 milliohms per contact, depending on mating force and plating thickness. For high-speed digital applications (>100 MHz), contact resistance introduces minimal signal degradation if PCB traces are properly impedance-controlled and connector lead inductance is accounted for. For precision analog circuits (sub-millivolt accuracy), the SSW-110-06-T-S contact resistance may contribute unwanted offset if signal levels are in the microvolt range; in such cases, measure or specify expected contact resistance during design validation. Gold-plated alternatives (such as Amphenol FCI 67996 series) typically offer lower and more stable contact resistance over time, but at higher cost. If contact resistance stability is critical, design differential signaling paths or active compensation to mitigate the SSW-110-06-T-S variability.
• Is the SSW-110-06-T-S suitable for medical device, aerospace, or automotive applications that require traceability, lot-level documentation, or specialized qualification? The SSW-110-06-T-S carries RoHS3 compliance and EAR99 export classification, meeting general environmental and regulatory baseline requirements. However, medical device (FDA/ISO 13485), aerospace (AS9100), and automotive (IATF 16949) applications typically require additional qualification documentation, such as source inspection reports, counterfeit mitigation evidence, and extended traceability. Samtec can provide datasheets and RoHS certificates, but medical and aerospace applications often mandate first-article inspection (FAI), environmental testing (humidity, thermal shock, vibration per MIL-STD-810), and printed box traceability by manufacturing lot. Before selecting the SSW-110-06-T-S for regulated applications, verify that Samtec's published specifications and supply chain documentation align with your industry's requirements. If specialized certifications are needed, contact Samtec's applications engineering team early to confirm availability and lead times for qualified product variants.
