WTB120SAD9JTB

Overview

The WTB120SAD9JTB is a rectangular MIL-DTL-55302 series connector manufactured by Molex / AirBorn. It features a straight receptacle design with 120 positions arranged in two rows. The component utilizes through-hole termination for board mounting and incorporates gold-plated copper alloy socket contacts. Constructed with a polyphenylene sulfide (PPS) housing, it supports a current rating of 5 A and a voltage rating of 1 kV. The unit operates within a temperature range of -65 C to +125 C and maintains an insulation resistance of 5 GOhms at a 2.54 mm pitch.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for high-reliability interconnects
• Features gold-plated copper alloy female contacts for durable signal transmission
• Utilizes Polyphenylene Sulfide (PPS) housing for thermal stability
• Designed for vertical board mount applications via through-hole soldering

Applications

• Military aerospace electronic systems
• High-density board-to-board interconnections
• Ruggedized industrial control equipment
• Avionics signal routing modules

Procurement Notes

Verify the specific suffix JTB against official Molex / AirBorn documentation to confirm plating thickness and environmental sealing ratings. Ensure compatibility with mating plugs regarding contact gender and row alignment. Confirm RoHS compliance status and lead-free requirements prior to procurement. Validate that the 120-position density matches the target PCB footprint constraints.

Selection Notes

Select this component when a high-pin-count, dual-row MIL-Spec receptacle is required for rigid board mounting. The 2.54 mm pitch accommodates standard wiring densities. Verify that the 5 A current rating per contact meets the circuit load requirements. Consider the straight orientation for direct panel or chassis integration without angular adapters.

Part Context

This part belongs to the AirBorn W Series, a family of rectangular connectors designed for mission-critical environments. The series offers various position counts and termination styles while maintaining strict adherence to MIL-DTL-55302 standards. The WTB120SAD9JTB represents a high-density solution within this lineup, providing robust connectivity for demanding operational conditions.

Replacement Considerations

Cross-reference with M55302/60-C120Y-3 as a potential equivalent designation. Verify mechanical dimensions and contact configuration before substitution. Ensure any replacement part meets the same MIL-DTL-55302 performance criteria.
