Procurement Notes

Verify the specific suffix codes against official AirBorn documentation to confirm exact contact arrangements and mating compatibility. Ensure that the ordering information matches the required MIL-DTL-55302 revision levels. Cross-reference part numbers with authorized distributors to confirm authenticity and traceability before finalizing procurement decisions.

Selection Notes

Select this component when a compact, high-reliability interconnect solution is required for space-constrained military or industrial designs. The 2.54 mm pitch allows for standard wiring harnesses, while the PPS material offers superior thermal stability compared to standard thermoplastics. Evaluate the operating temperature requirements to ensure they fall within the specified -65°C to +125°C range for optimal performance.

Part Context

This part belongs to the AirBorn W Series, which is widely recognized for its robust construction and compliance with stringent military standards. The M55302 designation indicates adherence to the MIL-DTL-55302 specification, ensuring interchangeability and reliability in critical defense and aerospace applications where failure is not an option.

Replacement Considerations

Direct replacements must match the MIL-DTL-55302 specification and maintain identical pin configurations. Verify compatibility with existing mating receptacles and panel cutouts. Consult manufacturer cross-reference guides for equivalent parts from other qualified suppliers.
