Headers, Male Pins Procurement Notes

Verify the specific suffix variant against official datasheets, as ordering codes may denote distinct environmental or mechanical attributes. Confirm RoHS compliance status directly with the manufacturer documentation. Ensure the procurement channel provides traceable certificates of conformity. Cross-reference the part number alias M55302/57A70Y to validate equivalence in legacy systems. Request updated manufacturing data sheets prior to finalizing orders.

Headers, Male Pins Selection Notes

Select this component when a high-density 70-position connection is required in a constrained space due to its right-angle profile. The dual-row arrangement supports extensive signal routing within a compact footprint. Verify that the 2.54 mm pitch aligns with existing PCB layout constraints. Ensure the thermal environment remains within the specified -65 C to +125 C operational limits. Confirm compatibility with through-hole assembly processes and appropriate soldering profiles.

Headers, Male Pins Part Context

This connector belongs to the AirBorn W Series, a line of rectangular MIL-Spec connectors designed for rugged environments. The series is characterized by high contact density and robust mechanical performance. AirBorn, now part of Molex, specializes in specialized electronic solutions for aerospace and defense sectors.
