HDASE202YD-000LF

Overview

The Amphenol HDASE202YD-000LF is a rectangular MIL-spec receptacle connector from the HDAS series, compliant with MIL-DTL-55302G. It features 202 positions arranged in three rows with a 1.905 mm pitch. Designed for PCB mount installation, it utilizes straight solder tail contacts with gold plating on copper alloy sockets. The housing is constructed from liquid crystal polymer (LCP), supporting high-temperature and lead-free soldering processes. Electrical ratings include a current capacity of 4.5 A per contact and a voltage rating of 750 V. The unit operates within a temperature range of -65°C to +150°C and offers an insulation resistance of 5 GOhms.

Feature Summary

• Provides Cat6A Ethernet connectivity capabilities alongside full sealing to IP6X specifications
• Utilizes star-clamp technology for socket contacts to ensure reliable performance under high vibration
• Incorporates side rails on male connectors to protect contacts from external damage
• Employ LCP material construction to support various welding types including high-temperature processes

Applications

• Harsh environment applications requiring high reliability and cost-effectiveness
• Systems demanding high-density interconnects with extreme condition tolerance
• Military and aerospace installations exceeding standard MIL-DTL-55302 requirements

Procurement Notes

Verify the specific revision status against the latest manufacturer datasheet before integration. Confirm that the 202-position configuration aligns with panel cutout dimensions and PCB layout constraints. Ensure compatibility with mating male connectors featuring protective side rails. Validate thermal profiles during assembly to maintain LCP integrity and solder joint quality. Cross-reference pin-out assignments with system schematics to prevent wiring errors.

Selection Notes

Select this component when high contact density is required within a rectangular form factor. Consider the 1.905 mm pitch for space-constrained designs needing robust signal transmission. Evaluate the IP6X sealing requirement if environmental protection is critical. Assess the 4.5 A current rating per contact against total load distribution across the 202 positions. Verify that the straight PC tail style matches the target PCB mounting orientation and thickness.

Part Context

This part belongs to the HDAS series of high-performance PCB connectors designed by Amphenol Socapex. The series emphasizes compact spacing and increased contact density for demanding applications. It serves as a rugged alternative to standard commercial connectors, offering enhanced durability against heat and vibration. The HDAS line supports both military and commercial aerospace markets through its compliance with stringent standards.

Replacement Considerations

Direct substitutes must match the 202-position count, 1.905 mm pitch, and MIL-DTL-55302G compliance. Verify identical housing material (LCP) and contact plating (gold) for electrical equivalence. Ensure the replacement maintains the same straight PCB mount configuration and IP6X sealing capability.
