WTA44PCJTA

Overview

The WTA44PCJTA is a rectangular MIL-DTL-55302 series connector manufactured by Molex / AirBorn. It features a straight plug configuration with 44 positions arranged in two rows. The unit utilizes solder cup termination for wire connections and incorporates gold-plated copper alloy pin contacts. Designed for board mounting, the housing is constructed from Polyphenylene Sulfide (PPS). Key electrical ratings include a current capacity of 5 A and a voltage rating of 1 kV. The component operates within a temperature range of -65 C to +125 C, maintains an insulation resistance of 5 GOhms, and uses a 2.54 mm contact pitch suitable for 22 AWG wire.

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to ensure correct termination style and contact orientation. Confirm RoHS compliance status and environmental certifications prior to integration. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity. Ensure mating connectors match the specified gender and row configuration.

Selection Notes

Select this model when a straight-mount plug with solder cup termination is required for high-density wiring. The 44-position layout supports extensive signal routing in constrained spaces. Verify that the 2.54 mm pitch aligns with existing PCB or cable harness designs. Consider the operating temperature range and voltage ratings to ensure compatibility with system electrical requirements.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors designed for demanding environments. The series offers various position counts and termination options to meet diverse military and industrial standards. The WTA44PCJTA specifically addresses needs for robust, high-pin-count interconnections in critical infrastructure.

Replacement Considerations

Compatible substitutes include other MIL-DTL-55302 compliant connectors with matching 44-position, 2-row configurations. Verify mechanical dimensions, contact plating, and termination methods before substitution. Equivalent parts may carry different manufacturer suffixes but must adhere to the same performance specifications.
