Headers, Male Pins Procurement Notes

Verify the specific manufacturer part number against official Molex/AirBorn documentation to ensure compatibility with MIL-DTL-55302 requirements. Confirm that the ordering suffix matches the required contact configuration and mounting style. Request current availability status directly from authorized distributors or the manufacturer, as lead times may vary for factory special orders. Ensure all environmental certifications align with project specifications before finalizing procurement.

Headers, Male Pins Selection Notes

Select this component when a high-density, dual-row rectangular connector is required for board-to-board or cable-to-board connections in demanding environments. The 2.54 mm pitch allows for standard PCB layouts while maintaining robust mechanical integrity. Consider the straight plug configuration for direct panel or chassis mounting applications where space constraints allow. Verify that the 5 A current rating per contact meets the system's power distribution needs.

Headers, Male Pins Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors designed for military and aerospace applications. The series emphasizes durability and performance in harsh conditions. The WTAV40PD9J specifically represents a 40-position variant within this family, sharing common design principles with other models like the WTBV and WGV series but differing in position count and specific mounting details.

Headers, Male Pins Replacement Considerations

Check for cross-reference part numbers such as M55302/63B40X if available in official substitution guides. Ensure any replacement maintains the same MIL-DTL-55302 compliance, pinout configuration, and physical dimensions. Verify that the substitute component offers equivalent electrical ratings and environmental tolerance levels.
