WGA122PR7SY-7

Overview

The WGA122PR7SY-7 is a rectangular MIL-DTL-55302 series connector manufactured by Molex / AirBorn. It is a board mount plug featuring pin contacts with a right-angle through-hole termination style. The component utilizes a three-row configuration with a 2.54 mm pitch and supports 122 circuits. Constructed with a polyphenylene sulfide (PPS) body and gold-plated copper alloy contacts, it operates within a temperature range of -65°C to +125°C. Rated for 5 A current and 1 kV voltage, it includes mounting ears and a fixed jackset design.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged reliability
• Features a right-angle through-hole mounting configuration for space-efficient PCB integration
• Utilizes gold-plated copper alloy contacts to ensure stable signal transmission
• Incorporates a durable polyphenylene sulfide housing for thermal stability

Applications

• Aerospace avionics systems requiring high-density interconnects
• Defense communication equipment subject to strict environmental standards
• Industrial control panels utilizing MIL-Spec connectors
• Radar and navigation subsystems in harsh operating environments

Procurement Notes

Verify the specific polarization code suffix against the official datasheet to ensure correct mating compatibility. Confirm that the manufacturing origin aligns with required defense sourcing regulations. Check for recent product change notifications regarding material substitutions or process updates. Ensure the ordering quantity matches the single-unit factory packaging standard. Validate RoHS compliance status if restricted substances are mandated by the end application.

Selection Notes

Select this model when a high-circuit-count, right-angle board mount solution is required. The 2.54 mm pitch accommodates standard wiring harnesses while maintaining compact density. The PPS material offers superior heat resistance compared to standard thermoplastics. Gold plating provides reliable conductivity for critical signal paths. Ensure the PCB layout supports the three-row pin arrangement and mounting ear clearance.

Part Context

This component belongs to the AirBorn W Series, a family of rectangular connectors designed for demanding applications. The series emphasizes durability and consistent performance under severe mechanical and thermal stress. The WGA variant specifically denotes a plug configuration with integrated mounting features. This lineage ensures interoperability with other W Series receptacles and accessories.

Replacement Considerations

Direct replacements must match the MIL-DTL-55302 specification and physical dimensions. Verify identical circuit count, row configuration, and contact type before substitution. Cross-reference the polarization key to prevent mating errors. Ensure the replacement part maintains the same current and voltage ratings.
