HDASF041YD6A-000

Overview

The HDASF041YD6A-000 is a rectangular MIL-spec connector header from the Amphenol HDAS series, designed for board-to-board applications. It features a 3-row configuration with 47 positions and a 1.905 mm (0.075 inch) pitch. The component utilizes through-hole solder termination and includes a threaded locking mechanism for secure attachment. Constructed with liquid crystal polymer (LCP) housing and gold-plated copper alloy contacts, it supports a current rating of 4.5 A per contact and withstands voltages up to 750 V. Operating temperatures range from -65°C to +125°C.

Feature Summary

• Threaded locking mechanism ensures secure mating in high-vibration environments
• Dual-wall shrouded design provides enhanced environmental protection
• Gold-plated contacts ensure reliable signal transmission and corrosion resistance

Applications

• Military avionics systems requiring MIL-DTL-55302G compliance
• Ruggedized electronic equipment operating in extreme temperatures
• High-density board-to-board interconnects in defense platforms

Procurement Notes

Verify the specific suffix '6A' against official Amphenol documentation to confirm exact shell size, plating specification, and mounting flange configuration. Ensure compatibility with corresponding receptacle models within the HDAS series. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary by region.

Selection Notes

Select this model when a rigid, threaded connection is required for high-reliability board-to-board interfaces. The 3-row layout maximizes pin density within a compact footprint. Verify that the PCB layout accommodates the 1.905 mm pitch and through-hole soldering requirements. Consider the thermal limits of the LCP housing if operating near the upper temperature threshold.

Part Context

This component belongs to the HDAS hybrid plug series, which combines rectangular connector functionality with circular connector durability standards. The series is characterized by its robust construction and suitability for harsh environments. The HDASF041YD6A-000 specifically represents a straight-mount header variant with threaded engagement, distinct from right-angle or quick-connect alternatives in the same family.

Replacement Considerations

Direct substitutes include other HDAS series headers with identical 47-position, 3-row configurations and threaded locking mechanisms. Cross-reference part numbers such as HDASF041YC6A-000 for similar specifications, noting differences in orientation or termination style. Ensure any replacement matches the MIL-DTL-55302G form factor and electrical ratings.
