WTKA10SJTB

Overview

The WTKA10SJTB is a rectangular MIL-Spec connector from the AirBorn W Series, compliant with MIL-DTL-55302. It features a straight cable mount receptacle configuration with two rows and ten positions. The unit utilizes crimp termination for socket contacts plated with gold, housed in a Polyphenylene Sulfide (PPS) shell. Constructed with beryllium copper contacts, it supports a current rating of 5 A and operates within a temperature range of -65 C to +125 C. The connector maintains an insulation resistance of 5 GOhms and employs a 2.54 mm pitch.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for high-reliability interconnects
• Features gold-plated beryllium copper socket contacts for durable signal transmission
• Utilizes Polyphenylene Sulfide housing material for thermal stability
• Designed for straight cable mounting applications requiring secure crimp termination

Applications

• Military aerospace avionics systems
• Ruggedized communication equipment
• Defense electronics assemblies
• Harsh environment industrial control interfaces

Procurement Notes

Verify that the specific part number matches the required MIL-DTL-55302 compliance level and contact configuration. Confirm that the crimp tooling is compatible with the specified wire gauge and terminal type. Ensure environmental sealing requirements align with the PPS housing capabilities. Validate that the straight cable mount style fits the mechanical constraints of the assembly. Check for any specific lot traceability documentation required by the end application standards.

Selection Notes

Select this component when a MIL-DTL-55302 compliant, 10-position, two-row receptacle is required for cable-to-cable or cable-to-panel connections. Choose this model for its robust beryllium copper contacts and gold plating suitable for frequent mating cycles. Consider the 2.54 mm pitch and straight orientation for standard wiring harness layouts. Evaluate the -65 C to +125 C operating range against the environmental conditions of the deployment site.

Part Context

This connector belongs to the AirBorn W Series, known for high-density interconnect solutions in demanding environments. The series offers various configurations including plugs and receptacles with different contact counts and termination styles. The WTKA10SJTB specifically addresses needs for reliable, small-form-factor connections in military and aerospace sectors where vibration resistance and electrical performance are critical.

Replacement Considerations

Compatible mating parts include corresponding W Series plugs such as WTDA10PCJTB. Verify pin-to-socket compatibility and shell size alignment before substitution. Cross-reference with other manufacturers' MIL-DTL-55302 equivalents if supply chain constraints require alternative sourcing.
