Headers, Male Pins Procurement Notes

Verify the exact suffix designation against official manufacturer documentation to confirm terminal plating thickness and contact material variations. Ensure that the ordering information matches the required MIL-DTL-55302 revision level. Confirm compatibility with mating receptacles regarding shell size and keying options. Validate environmental sealing requirements if exposed to harsh conditions. Cross-reference the specific part number with current datasheets to avoid obsolete variants.

Headers, Male Pins Selection Notes

Select this component when a 40-position high-density interface is required in a compact footprint. Consider the right-angle orientation for space-constrained chassis layouts. Evaluate the solder termination method against available assembly capabilities. Assess the thermal performance limits relative to the operational environment. Compare the mechanical durability requirements against the standard military specification ratings provided in the technical data.

Headers, Male Pins Part Context

This connector belongs to the AirBorn W Series, a line of rectangular connectors designed for demanding applications. The series is characterized by its small form factor and high contact density. Manufactured under the Molex brand, these components adhere to strict quality standards.
