68031-213HLF

FAQFrequently Asked Questions

• Can the 68031-213HLF be used as a direct replacement for older DIP header connectors in legacy board designs? The 68031-213HLF is a BERGSTIK® II 13-position through-hole header with 0.100" (2.54mm) pitch, which matches standard DIP spacing. However, compatibility depends on the original connector's shrouding design and fastening mechanism. The 68031-213HLF features unshrouded construction and push-pull fastening, which may differ from older headers that used friction-fit or keyed designs. Before substitution, verify that the mating connector's retention method and polarization scheme align with the push-pull engagement of the 68031-213HLF.
• What are the design implications of the 68031-213HLF's gold contact finish thickness of 15.0µin (0.38µm) for high-cycle mating applications? The 68031-213HLF employs gold or gold GXT™ contact finish at 15.0µin (0.38µm) thickness over phosphor bronze base material. This thin finish is typical for general-purpose headers but may accelerate wear in applications exceding 1000 mating cycles annually. In high-cycle scenarios, thicker gold plating (25–50µin) or selective hard-gold contacts reduce corosion and contact resistance drift. For industrial environments with frequent connector insertion-removal cycles, evaluate whether the 68031-213HLF's contact durability meets your expected service life, or consider alternative headers with reinforced contact metallurgy.
• Is the 68031-213HLF suitable for high-temperature industrial control applications, and what thermal limitations should I consider? The 68031-213HLF specifications do not explicitly list an operating temperature range, which is a significant constraint for industrial thermal applications. While the insulation material achieves UL94 V-0 flammability rating, the absence of published thermal limits suggests this header may not be rated for extended operation in high-temperature environments (above 70°C ambient). For industrial control or thermal management applications, contact Amphenol ICC for detailed thermal derating curves, or specify headers with explicit temperature ratings (typically –40°C to +85°C or higher) to ensure reliability across your operating envelope.
• How does the 68031-213HLF's 5A current rating per contact impact power delivery in multi-position applications? The 68031-213HLF carries a 5A per-contact current rating at 110V voltage maximum. In a13-position configuration, aggregate current delivery approaches 65A if all positions conduct simultaneously, but practical thermal and PCB routing constraints typically limit actual current. The contact resistance of gold-plated phosphor bronze increases with temperature; sustained operation near 5A per contact will generate localized heating. For power-critical designs, calculate contact voltage drop (typically 10–50mV per contact at full current) and thermal rise to determine if de-rating is necessary. Consider whether clustering power returns on fewer contacts creates hotspots that exceed safe dissipation limits.
• What is the solder joint reliability of the 68031-213HLF's 0.183" (4.65mm) post length in high-vibration or shock environments? The 68031-213HLF features solder-terminated posts of 0.183" (4.65mm) length, which provide a relatively short mechanical lever arm for PCB-mounted stress. In vibration or shock-prone applications (automotive, industrial machinery, military), short post length reduces flexure and improves fatigue resistance compared to longer headers. However, the through-hole solder joint itself remains a stress concentration point. To enhance reliability, employ solder mask defined (SMD) landing pads, increase pad size if PCB thickness permits, and consider secondary mechanical support (strain relief clips or conformal coating) if vibration levels exceed 2G RMS continuous acceleration.
• Can the unshrouded design of the 68031-213HLF create cross-talk or signal integrity issues in high-speed applications? The 68031-213HLF is an unshrouded header, meaning adjacent contacts are not electromagnetically isolated. In high-speed digital applications (>10 Mbps per line), this design can introduce capacitive coupling between signal lines and shared ground/power returns, leading to crosstalk and timing skew. If your design includes sensitive analog signals or high-frequency clocking, evaluate the spacing of signal and ground contacts on the 68031-213HLF pin field. Consider interleaving ground returns between signal lines or specifying a shrouded variant to reduce common-mode interference. Additionally, verify that the PCB trace routing maintains adequate separation from the connector region.
• Is the 68031-213HLF compatible with automated insertion-extraction tooling, or does the push-pull fastening require manual engagement? The 68031-213HLF employs push-pull fastening, which requires deliberate mechanical engagement and disengagement of the mating connector. This design is not compatible with automated blind-mate or quick-disconnect tooling commonly used in high-volume manufacturing or field-replaceable module scenarios. If your application demands automated mating, rapid connector swaps, or blind-mate capability, the 68031-213HLF's push-pull design necessitates manual intervention, potentially increasing service time and labor costs. Consider alternative BERGSTIK® II variants with latch or keyed features if automation is required.
• What precautions should be taken during PCB assembly when soldering the 68031-213HLF to prevent solder bridge formation between adjacent contacts? The 68031-213HLF's 0.100" (2.54mm) pitch results in 0.065–0.075" spacing between adjacent contacts, a typical DIP pitch that offers moderate susceptibility to solder bridging during wave or reflow soldering. To mitigate risk: (1) apply solder mask between contact lands with minimum 0.008–0.010" width to block solder wicking, (2) use controlled solder volume (typically 50–70% of pad height), and (3) verify that reflow temperatures do not exceed the recommended peak of 260°C for more than 10 seconds, as excessive heat promotes solder flow between closely spaced posts. For critical applications, consider X-ray inspection post-assembly to verify the integrity of internal solder joints.
• How does the REACH and ECCN classification of the 68031-213HLF affect supply chain and export compliance? The 68031-213HLF is classified as REACH Affected with ECCN designation EAR99, meaning it is subject to EU environmental compliance regulations and U.S. export control screening. REACH Affected status requires documentation of substance restrictions and may necessitate supplier declaration forms certain substances (lead-free solder requirements, restricted heavy metals). EAR99 classification places the connector outside of strict munitions control, but export to sanctioned countries or sensitive end-uses may still require authorization. Before finalizing designs or supply agreements, consult with your procurement and legal teams to ensure compliance with your target markets' regulatory requirements.
• What is the effective lifespan of the 68031-213HLF in static storage conditions given its MSL 1 rating, and are there desiccant or climate-controlled storage requirements? The 68031-213HLF carries Moisture Sensitivity Level (MSL)1, indicating unlimited floor life and no special dry storage requirements prior to soldering. This designation means the connector can remain in normal ambient humidity (30–70% RH) indefinitely without moisture absorption or mechanical degradation. Unlike MSL 2–4 components that require baked-out conditioning after storage, the 68031-213HLF can be removed from packaging and used directly without pre-solder bake cycles. However, once soldered to the PCB, long-term environmental exposure (salt fog, high humidity, thermal cycling) may degrade the phosphor bronze base or gold finish; applying conformal coating provides extended protection in harsh industrial or marine environments.
• How should the 68031-213HLF be specified in a connector replacement kit to ensure backward compatibility with existing field installations? When specifying the 68031-213HLF as a replacement part in customer documentation, include the full manufacturer part number (68031-213HLF), the base product number (68031), and the specific series designation (BERGSTIK® II) to prevent confusion with similar13-position headers from other manufacturers. Supply mating cable assemblies that explicitly reference the push-pull fastening mechanism and verify that end-users understand the connector orientation and engagement depth (5.84mm mating contact length). If field replacement is performed by non-technical personnel, provide visual installation guides or color-coded keying aids to reduce insertion errors. Document the 0.100" pitch and contact pattern to allow field verification against existing installed hardware.
• What design trade-offs exist between the 68031-213HLF and compact alternates (such as 0.050" pitch connectors) for space-constrained PCB layouts? The 68031-213HLF's 0.100" (2.54mm) pitch occupies approximately 1.2" linear footprint for 13 positions, whereas 0.050" pitch alternatives reduce this to ~0.6". However, this compaction introduces higher contact density, which increases crosstalk risk, complicates trace routing beneath the connector, and reduces solder joint accessibility for rework. Additionally, 0.050" pitch connectors typically command 20–30% higher unit costs and require smaller gauge wires, increasing assembly labor. The 68031-213HLF is better suited for applications where component accessibility, robustness, and cost are prioritized over extreme space efficiency. Evaluate your board layer count, trace density, and service requirements before adopting sub-0.100" pitch alternatives.
