RM342-122-511-5900

Headers, Receptacles, Female Sockets Overview

The RM342-122-511-5900 is a rectangular MIL-spec receptacle from the AirBorn R Series, manufactured by Molex. It features a plastic body with three rows and 122 positions, utilizing a 1.91 mm pitch. Designed for board mount installation, this straight connector employs through-hole termination. The contacts are female sockets made of beryllium copper and brass, finished with gold plating to ensure reliable signal transmission. Constructed with Polyphenylene Sulfide (PPS) housing, it supports an operating temperature range from -65 °C to +125 °C and carries a 3 A current rating per contact.

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix against the official Molex/AirBorn datasheet to confirm exact pin count, termination style, and jackset configuration. Ensure compatibility with mating connectors within the same R Series family. Confirm RoHS status and material composition requirements prior to procurement, as variations exist across similar part numbers.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a high-density, vertically mounted receptacle is required for MIL-Spec applications. The 122-position capacity and 1.91 mm pitch define the spatial constraints. Verify that the through-hole termination method aligns with the PCB fabrication capabilities and that the gold-plated contacts meet the electrical reliability standards for the intended circuitry.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the AirBorn R Series, a line of rectangular MIL-spec connectors known for durability. The 'RM' prefix typically denotes a receptacle configuration. As a Molex company product, it adheres to strict quality controls. This specific model represents a high-pin-count solution designed for demanding industrial and military sectors where vibration resistance and environmental sealing are critical.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 122 position count, 3-row layout, and 1.91 mm pitch. Verify that any alternative maintains the same MIL-DTL-55302 compliance and physical dimensions to ensure interchangeability without modifying the host PCB or enclosure design.
