RC442-052-301-3900

Headers, Receptacles, Female Sockets Overview

The AirBorn RC442-052-301-3900 is a rectangular military specification connector from the RC Series, manufactured by Molex. It features a board-to-board configuration with 52 positions arranged in four rows. The connector utilizes press-fit termination and gold-plated beryllium copper female sockets. Designed for stackable applications, it offers a 0.075-inch (1.91 mm) pitch. The housing is constructed from polyphenylene sulfide (PPS), supporting an operating temperature range of -65°C to +125°C. It complies with MIL-DTL-55302 standards.

Headers, Receptacles, Female Sockets Procurement Notes

Verify current availability directly with Molex or authorized distributors, as this component may be subject to factory special order status. Confirm that the specific suffix matches the required pin count and contact type. Ensure environmental certifications align with project requirements before finalizing procurement orders.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when a stackable, press-fit solution is required for rigid board-to-board connections. The 52-position, four-row layout suits applications needing moderate density in a compact footprint. Verify that the 1.91 mm pitch fits the target PCB layout constraints and that the operating temperature range meets the system's thermal environment specifications.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the AirBorn RC Series, which specializes in rectangular, high-density connectors for demanding environments. The series is known for its robust construction and compliance with stringent military standards. The RC442 variant specifically denotes a stackable header configuration, distinguishing it from single-level receptacles within the broader product family.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 52-position, 4-row, press-fit, female socket configuration with identical 1.91 mm pitch. Cross-referencing with other manufacturers requires verifying MIL-DTL-55302 compatibility and physical dimensions. No generic equivalents are confirmed; only exact functional matches should be considered.
