WTA70PCJTB

Overview

The AirBorn WTA70PCJTB is a rectangular MIL-DTL-55302 series connector designed for board mount applications. It features a straight plug configuration with 70 positions arranged in two rows. The contacts are male pins with gold plating, utilizing a solder cup termination type. Constructed with a polyphenylene sulfide (PPS) housing and copper alloy contacts, it supports a current rating of 5 A and a voltage rating of 1 kV. The component operates within a temperature range of -65°C to +125°C, offering an insulation resistance of 5 GOhms at a 2.54 mm pitch.

Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to ensure correct contact orientation and mounting variations. Confirm RoHS compliance status as required by project specifications. Check for alternate part numbers such as M55302/63A70H which may represent equivalent government stock numbers. Ensure the solder cup termination matches the PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this model when a high-pin-count, two-row straight plug is required for board-to-board or cable-to-board connections in harsh environments. The 70-position capacity suits complex signal routing needs. Verify that the 5 A current rating per contact aligns with the circuit load. Consider the solder cup termination method for assembly compatibility. Ensure the operating temperature range meets the environmental conditions of the deployment site.
