71-529703-98Y

Overview

The Amphenol Aerospace Operations 71-529703-98Y is a MIL-DTL-55302 Series W rectangular connector designed for high-reliability applications. It features a brush-type contact interface and supports up to 72 positions with a 0.100-inch (2.54 mm) pitch. The component utilizes a solder termination method for printed circuit board mounting and includes an integrated mounting flange for secure installation. Rated for operation between -65°C and +125°C, it meets stringent environmental standards required for aerospace and military systems.

Feature Summary

• Brush-type contact technology ensures reliable signal transmission in harsh environments
• Integrated mounting flange provides structural stability during vibration
• Solder termination facilitates direct PCB integration

Applications

• Aerospace avionics systems
• Military communication equipment
• Radar and navigation subsystems

Procurement Notes

Verify the specific series designation and contact configuration against official Amphenol datasheets before procurement. Ensure compatibility with mating connectors regarding pin count and orientation. Confirm that the supplier provides traceable documentation for MIL-DTL-55302 compliance. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component when a ruggedized rectangular connector with brush contacts is required for space-constrained PCB designs. Evaluate the 72-position capacity against system I/O requirements. Consider the operating temperature range and voltage ratings relative to the application environment. Verify that the solder termination type aligns with the manufacturing assembly process.

Part Context

This part belongs to the MIL-DTL-55302 Series W family of rectangular connectors manufactured by Amphenol Aerospace Operations. These connectors are engineered for demanding conditions where standard interconnects may fail. The Series W specifically denotes brush-style contacts, offering a compact form factor suitable for high-density backplane and board-level applications in defense and aerospace sectors.

Replacement Considerations

Check for equivalents within the same MIL-DTL-55302 Series W family from other qualified manufacturers. Verify dimensional compatibility and electrical specifications before substitution. Ensure any replacement maintains the same brush contact technology and mounting flange design.
