RC442-028-331-4200

Headers, Receptacles, Female Sockets Overview

The RC442-028-331-4200 is a rectangular board-to-board connector from the AirBorn R Series, manufactured by Molex. It features a 0.075-inch (1.91 mm) pitch with 4 rows and 7 columns, totaling 28 positions. The component utilizes press-fit termination for board mounting and includes female socket contacts made of beryllium copper with gold plating. Constructed with a polyphenylene sulfide (PPS) housing, it supports a current rating of 3 A and operates within a temperature range of -65°C to +125°C.

Headers, Receptacles, Female Sockets Feature Summary

• Provides secure mechanical retention through a press-fit termination method suitable for board-mounted applications.
• Ensures reliable electrical contact using gold-plated beryllium copper sockets arranged in a four-row configuration.
• Features a robust polyphenylene sulfide (PPS) housing designed for durability in demanding environments.

Headers, Receptacles, Female Sockets Applications

• High-density interconnects in military and aerospace systems
• Stackable board architectures requiring rigid alignment
• Avionics modules needing MIL-DTL-55302 compliance

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm mating compatibility and termination style. Confirm RoHS status and material declarations directly with the manufacturer or authorized distributors prior to ordering. Ensure that the selected variant matches the required guide pin and mounting ear specifications for the target assembly.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when a 28-position, 4-row interface is required with a 1.91 mm pitch. The press-fit termination is ideal for high-reliability applications where soldering is not preferred. Ensure the mating connector provides corresponding male pins and compatible guide structures for proper alignment during assembly.
