223980-1

FAQFrequently Asked Questions

• Can the TE Connectivity 223980-1 UPM connector be used as a direct replacement for the 5223968-1 in existing backplane designs? The TE Connectivity 223980-1 and 5223968-1 are listed as substitutes, but direct interchangeability depends on mechanical fit and electrical requirements of your specific application. Both are 3-position male blade power headers with board edge mounting, but you should verify connector body dimensions, contact spacing, and insertion force specifications against your PCB layout and mating connector specifications. If your design uses press-fit termination and requires the same contact finish (gold or gold-palladium), mechanical compatibility testing is recommended before production transition.
• What are the design implications of the 223980-1's board edge, right-angle mounting for high-current power distribution backplanes? The TE Connectivity 223980-1 uses through-hole press-fit termination with right-angle board edge mounting, which creates a direct connection path perpendicular to the PCB plane. This configuration minimizes loop inductance for the three power positions and suits low-impedance power delivery designs. However, the right-angle orientation requires sufficient vertical clearance on your backplane assembly and may limit component placement density near the connector. For designs approaching or exceeding 20A per contact, verify that the press-fit termination footprint and via layout under each position can accommodate thermal expansion without delamination during thermal cycling.
• Is the TE Connectivity 223980-1 suitable for applications requiring frequent mating and de-mating cycles? The 223980-1 uses blade-type male contacts with gold or gold-palladium plating, which typically withstand 100+ mating cycles without degradation when mated against similarly plated female connectors. However, this connector is board-mounted via press-fit termination, making it permanently soldered to your backplane. If your application requires frequent connector changes, consider whether you need a mating connector with indexed keying and retention clips rather than relying solely on blade-to-blade friction. For industrial or field-service scenarios with planned disconnections, evaluate the mechanical durability of the 3-position layout under repeated handling stress.
• What are the RoHS compliance implications when specifying the 223980-1 for new product designs? The TE Connectivity 223980-1 is marked as RoHS non-compliant, meaning it contains restricted substances such as lead in solder or plating. If your application or end market requires RoHS certification—particularly for EU, automotive, or medical products—you must either select an alternative RoHS-compliant connector or obtain an exemption waiver from your compliance officer. Check TE Connectivity's current product portfolio for UPM series alternatives that meet RoHS standards, as connector offerings evolve. Document the non-compliance status in your bill of materials and supply chain communications to prevent costly assembly delays.
• Can the 223980-1 operate reliably in extended temperature cycling environments typical of industrial or aerospace applications? The TE Connectivity 223980-1 material flammability rating is UL94 V-0, indicating the connector body resists flame propagation, but specific operating temperature limits are not listed in standard datasheets. For industrial and aerospace designs, press-fit connectors typically operate from -40°C to +85°C; verify the exact temperature range by requesting the full datasheet or component specification sheet from TE Connectivity. If your application requires -55°C to +125°C operation (aerospace or downhole oil), confirm that the gold or gold-palladium contact plating maintains conductivity and the press-fit socket retention remains stable across the full temperature range, as thermal cycling can induce micro-motion and contact creep.
• How should the 223980-1 be configured for three-phase power distribution versus single-phase or mixed-signal backplanes? The TE Connectivity 223980-1 provides three 1-row, 1-column positions designed for three power lines (phase A, phase B, phase C or V+, GND, V-). Because all positions are identical male blade contacts with the same termination and finish, you must establish your own electrical design rules to designate which position carries which voltage level. There is no keying or asymmetry to prevent misalignment if the mating connector is installed inverted. For three-phase systems, use indexed keying on your mating female connector or clearly label the 223980-1 positions on the PCB silkscreen. For mixed-signal designs combining power and control signals, evaluate whether a specialized UPM connector with asymmetric keying would better suit your application.
• What press-fit termination and PCB footprint considerations apply when designing for the TE Connectivity 223980-1? The 223980-1 uses press-fit termination, requiring precise footprint dimensions, controlled via hole diameter, and PCB pad plating thickness to achieve consistent contact force and retention. Press-fit performance depends on PCB material modulus, typically FR-4 or polyimide, and degrades with thinner boards or boards that have been reworked multiple times. Verify hole spacing and diameter tolerances against TE Connectivity's press-fit design guidelines and confirm your PCB vendor can hold the required IPC-600 Class 3 tolerances. If your backplane undergoes thermal shock or experiences high vibration, consider reinforcing the press-fit retention with mechanical keying or alignment pins to prevent intermittent contact loss.
• Does the 223980-1 require special handling or moisture protection during assembly and storage? The TE Connectivity 223980-1 has a Moisture Sensitivity Level (MSL) of 1 (Unlimited), meaning it does not require moisture-controlled storage conditions and can be handled under standard ambient conditions without baking prior to assembly. This simplifies your supply chain logistics compared to MSL-3 or MSL-4 connectors, which require desiccant packaging and oven bake-out. However, if your PCB assembly process uses high-temperature solder reflow (above 260°C), the connector body and press-fit socket material must withstand brief thermal exposure; verify acceptable solder reflow temperatures in the connector datasheet to prevent permanent deformation or solder bridging across contacts.
• How does the 223980-1 contact finish affect reliability in high-humidity or corrosive environments? The TE Connectivity 223980-1 offers gold or gold-palladium contact plating, both of which provide corrosion resistance superior to tin or nickel finishes in humid or salt-spray environments. Gold maintains low contact resistance and is suitable for low-current signal applications; gold-palladium offers improved wear resistance for frequent mating cycles. However, neither finish alone prevents corrosion of the underlying copper or base metal if the plating thickness is insufficient or if the connector experiences galvanic coupling with dissimilar metals in a moist environment. For marine, coastal, or chemical processing applications, verify plating thickness meets ISO 4042 or equivalent standards and consider conformal coating or environmental sealing around the connector cavity.
• Is the 223980-1 suitable as a temporary or field-replaceable connector, or should it be considered a permanent assembly connection? The TE Connectivity 223980-1 is board-mounted via press-fit termination, which creates a permanent connection once inserted into the PCB. Unlike connectors with removable crimp contacts or modular pin insertion, the 223980-1 cannot be replaced without desoldering or mechanical removal of the entire connector from the board. For field service or maintenance scenarios, design your system with an external or intermediate connector that mates to the 223980-1; this isolates the permanent backplane connection and allows customers to swap mating cables or power modules without board rework. If your application requires connector replacement, consider whether a screw-terminal or blade-lock variant would better serve maintenance workflows.
