M55302/192LB122X

Headers, Receptacles, Female Sockets Overview

The M55302/192LB122X is a rectangular MIL-DTL-55302 connector from the AirBorn R Series, manufactured by Molex. It features a 122-position receptacle configuration designed for high-density interconnection applications. The component utilizes a 0.075-inch (1.91mm) contact spacing to maximize pin density within compact form factors. It employs a through-hole termination method suitable for printed circuit board mounting. The contacts are finished with gold plating to ensure reliable electrical performance and corrosion resistance in demanding environments.

Headers, Receptacles, Female Sockets Feature Summary

• High-density interconnection capability with 122 positions
• MIL-DTL-55302 compliance for military-grade reliability
• Gold-plated contacts for durable electrical connections
• Through-hole termination for secure PCB integration

Headers, Receptacles, Female Sockets Applications

• Mission-critical military systems requiring high reliability
• Aviation electronic interconnects
• Industrial control systems with extreme environment exposure
• High-density signal routing in ruggedized equipment

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix 'LB' against official AirBorn documentation to confirm exact mating interface and keying options. Ensure the 0.075-inch pitch specification aligns with the target PCB layout requirements. Confirm that the through-hole termination method is compatible with the assembly process. Cross-reference the 122-position count with schematic designs to prevent mismatch errors during integration.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when high pin density is required within strict MIL-DTL-55302 performance standards. The 0.075-inch spacing allows for more connections than standard 0.100-inch series. Consider the through-hole requirement for mechanical stability. Evaluate the gold plating necessity for long-term corrosion resistance in harsh operational conditions compared to alternative finishes.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the AirBorn R Series, which serves as a standard for high-density interconnections. The series meets or exceeds MIL-C-55302 performance specifications. AirBorn, now part of Molex, specializes in connectors for military, aviation, and industrial sectors. The R Series focuses on compact, rugged solutions for extreme environments.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the MIL-DTL-55302 specification, 122-position count, 0.075-inch pitch, and through-hole termination. Verify compatibility with existing mating connectors and panel cutouts before substitution.
