305-036-556-503

Edgeboard Connectors Overview

The EDAC Inc. 305-036-556-503 is a standard card edge connector featuring 36 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row spacing. Designed for .062 inch nominal thickness printed circuit boards, this female header employs gold-plated copper alloy contacts and solder pin termination. The unit supports a continuous current rating of 5 A and offers an insulation resistance of 5 GOhms, operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from thermoplastic material
• Provides high dielectric strength with a 1800 VACrms voltage rating

Edgeboard Connectors Applications

• High-density electronic module interconnections
• Industrial control system backplanes
• Telecommunications equipment signal routing

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm mechanical dimensions and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the dual-edge female gender matches the mating card edge design. Cross-reference the 305 series documentation for proper polarizing key integration requirements.

Edgeboard Connectors Selection Notes

Select this component when a robust connection for thick PCBs is required. The 3.96 mm pitch suits applications needing wider spacing than standard 2.54 mm connectors. The 5 A rating supports moderate power distribution alongside signal lines. Verify panel-mount installation needs as this model is designed for vertical mounting configurations.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and mounting styles. The 305-036-556-503 specifically addresses the need for a 36-position dual-row interface. It complements other 305 series headers by offering a standardized solution for modular electronics.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers within the 305 series sharing identical 36-position dual-row specifications. Verify matching pitch and PCB thickness tolerances before substitution. Alternative manufacturers may offer similar form factors but require electrical parameter validation.
