HDASF077YD-000

Overview

The HDASF077YD-000 is a 77-position rectangular connector header from the HDAS series, manufactured by Amphenol Aerospace Operations. It features a 1.91 mm (0.075 inch) pitch and is designed for board-to-board applications. The component utilizes a straight PCB tail configuration with gold-plated copper alloy contacts. Rated for 750V and 4.5A, it operates within a temperature range of -65°C to 125°C or 150°C depending on specific documentation. The housing is constructed from glass-filled liquid crystal polymer (LCP).

Feature Summary

• High-density interconnect design with 77 positions in a compact form factor.
• Robust insulation material composed of glass-filled liquid crystal polymer for thermal stability.
• Gold-plated contacts ensure reliable signal transmission and corrosion resistance.
• Includes mating and mounting flanges for secure mechanical alignment and installation.

Applications

• Board-to-board connections in industrial control systems.
• Signal and power distribution in aerospace avionics modules.
• Interconnection in defense electronics and harsh environment equipment.
• Data communication hardware requiring high-density pin arrangements.

Procurement Notes

Verify the exact operating temperature rating, as sources indicate variations between 125°C and 150°C. Confirm that the straight tail configuration matches the PCB layout requirements. Ensure compatibility with the corresponding HDAS series receptacle. Check for RoHS compliance status if required by project specifications. Validate contact plating thickness against environmental exposure needs.

Selection Notes

Select this model when a high-pin-count, low-pitch header is required for rigid board-to-board linking. The straight orientation suits vertical stacking or direct panel mounting scenarios. Consider the glass-filled LCP material for applications demanding dimensional stability under thermal cycling. Compare current ratings against total load requirements across all 77 positions.
