WTA70PCJTL

Overview

The AirBorn WTA70PCJTL is a rectangular MIL-DTL-55302 series connector plug featuring 70 positions in a dual-row configuration. It utilizes gold-plated copper alloy pin contacts with solder cup termination for board mounting. The housing is constructed from polyphenylene sulfide (PPS), supporting a 2.54 mm pitch and 22 AWG wire gauge. Rated for 1 kV voltage, 5 A current, and an insulation resistance of 5 GOhms, it operates within a temperature range of -65°C to +125°C.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged reliability
• Features gold-plated copper alloy male pin contacts for corrosion resistance
• Constructed with polyphenylene sulfide (PPS) housing for thermal stability

Applications

• Military aerospace avionics systems
• Ruggedized electronic equipment requiring MIL-Spec connectors
• High-density board-to-board interconnects

Procurement Notes

Verify the specific suffix JTL against official Molex/AirBorn documentation to confirm exact contact length and mounting ear configurations. Ensure compatibility with mating receptacles in the same W Series family. Cross-reference the alternate part number M55302/63A70L if sourcing through defense contractors. Confirm RoHS compliance status directly with the manufacturer as regulatory requirements may vary by production batch.

Selection Notes

Select this component when a high-density 70-position interface is required in space-constrained military applications. The straight board mount style suits vertical PCB integration. Verify that the 2.54 mm pitch aligns with existing footprint designs. Consider the PPS material properties for environments exceeding standard plastic limits. Ensure the solder cup termination method matches the assembly process capabilities.

Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors designed for harsh environments. The WTA70PCJTL specifically denotes a plug variant with 70 circuits. It is manufactured by Molex under the AirBorn brand, maintaining legacy MIL-DTL-55302 standards. The series is known for durability and consistent performance in demanding operational conditions.

Replacement Considerations

The part number M55302/63A70L serves as a confirmed equivalent designation. Verify mechanical dimensions and electrical ratings match exactly before substitution. Ensure mating interfaces are compatible with the W Series standard.
