HDASE029YD-000LF

Overview

The HDASE029YD-000LF is a rectangular MIL-DTL-55302G compliant receptacle connector from the HDAS series, manufactured by Amphenol Socapex. It features 29 positions arranged in a 3-row configuration with straight PCB mount installation. The contacts are gold-plated copper alloy sockets with a 1.905 mm pitch. Rated for 4.5 A current and 750 V voltage, it operates within a temperature range of -65°C to +150°C. The housing utilizes liquid crystal polymer (LCP), providing high insulation resistance of 5 GOhms and suitability for lead-free soldering processes.

Feature Summary

• High-density interconnect capability achieved through reduced spacing and cylindrical machined pins
• Robust contact retention utilizing star-clamp technology verified in socket configurations
• Enhanced mechanical protection via male connector side rails preventing external damage
• Thermal resilience supported by LCP material compatible with high-temperature soldering

Applications

• Military and aerospace systems requiring MIL-DTL-55302G compliance
• Harsh environment electronics demanding high vibration tolerance
• Space-constrained industrial equipment needing reliable signal transmission
• Avionics assemblies requiring high pin count in compact form factors

Procurement Notes

Verify that the specific part number corresponds to the Amphenol Socapex manufacturing origin rather than other Amphenol divisions, as datasheet sources may vary. Confirm RoHS compliance status and lead-free certification requirements against the latest official documentation. Ensure mating connectors match the 29-position, 3-row specification and jack screw coupling mechanism. Validate that the straight PC tail contact style aligns with the target PCB layout and soldering profile constraints.

Selection Notes

Select this component when high contact density is required within strict military specification boundaries. The 1.905 mm pitch allows for significant pin counts in limited board areas compared to standard rectangular connectors. Consider the LCP housing material if exposure to elevated temperatures or aggressive chemical environments is anticipated. The gold-plated contacts ensure low insertion force and reliable conductivity for sensitive signal applications. Evaluate the straight mounting orientation against available panel space and cable routing needs.

Part Context

This connector belongs to the HDAS family of high-performance PCB interconnects designed for extreme conditions. The series emphasizes reliability and simple design while minimizing footprint. HDAS components are engineered to exceed standard MIL-DTL-55302 requirements regarding thermal and vibrational stress. The product line supports various termination styles and position counts, catering to diverse ruggedized electronic system architectures.

Replacement Considerations

Direct substitutes must adhere to MIL-DTL-55302G standards with identical 29-position, 3-row geometry. Verify compatibility of the jack screw coupling interface and mounting flange dimensions. Ensure replacement parts maintain the 1.905 mm pitch and straight PCB tail configuration. Cross-reference insulation resistance and current rating specifications to guarantee equivalent electrical performance.
