WRD122SAD9JTA

Headers, Receptacles, Female Sockets Overview

The WRD122SAD9JTA is a rectangular MIL-DTL-55302 series board mount receptacle manufactured by Molex / AirBorn. It features 122 positions arranged in 4 rows with a 2.54 mm (0.100 inch) pitch. The connector utilizes gold-plated copper alloy socket contacts and a polyphenylene sulfide (PPS) plastic body. Designed for through-hole vertical mounting, it includes a turning jackset mechanism without mounting ears. Electrical specifications include a 5 A current rating, 5 GOhms insulation resistance, and an operating temperature range of -65°C to +125°C.

• Harsh environment industrial control panels

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix JTA against official Molex/AirBorn documentation to confirm the presence of the turning jackset and absence of mounting ears. Ensure the procurement specification matches the required 122-position count and 4-row layout. Confirm that the through-hole termination type aligns with the target PCB manufacturing capabilities. Cross-reference the MIL-DTL-55302 compliance requirements with the component datasheet before finalizing orders.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a high-pin-count, vertically mounted receptacle is required for MIL-SPEC applications. The 2.54 mm pitch accommodates standard wire gauges while maintaining density. Consider the turning jackset feature if secure mechanical locking is necessary without external fasteners. Verify that the PPS material properties meet the environmental exposure requirements of the deployment site.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the AirBorn W Series, a family of rectangular connectors designed for demanding military and aviation environments. The series emphasizes durability and high contact density. The WRD122SAD9JTA specifically addresses needs for large-scale signal routing in confined spaces, utilizing robust materials to withstand vibration and thermal cycling common in defense platforms.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible substitutes within the same family include WRDV122SAD9JTL, though terminal types differ. Direct replacements must maintain the 122-position count, 4-row arrangement, and 2.54 mm pitch. Verify that any alternative part number retains the turning jackset mechanism and compatible mating interface.
