305-048-521-203

Edgeboard Connectors Overview

The EDAC Inc. 305-048-521-203 is a standard card edge connector featuring 48 positions arranged in a dual row configuration. It utilizes a 0.156-inch (3.96 mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The component employs gold-plated copper alloy contacts with a half-bead termination type for reliable signal transmission. Designed for panel mounting at a vertical angle, it supports a continuous current rating of 5 A and operates 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 polyester
• Provides high dielectric strength with an insulation resistance of 5 GOhms

Edgeboard Connectors Applications

• Panel-mounted electronic interconnect systems requiring vertical orientation
• High-density circuit board connections utilizing polarizing keying mechanisms
• Industrial control modules operating within extended thermal environments

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official ordering guide to ensure correct flange and termination specifications. Confirm that the required PCB thickness aligns with the 1.57 mm design tolerance. Check regional distribution availability as stock levels may vary by location. Ensure compliance with RoHS3 and REACH regulations for the intended market application.

Edgeboard Connectors Selection Notes

Select this model when a dual-row, 48-position interface is required for vertical panel installation. The 3.96 mm pitch suits applications needing robust mechanical retention via polarizing keys. Consider the 5 A current rating and wide operating temperature range for demanding industrial or commercial environments where reliable long-term connectivity is essential.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, sharing common electrical characteristics such as the 5 A rating and gold-plated contact finish. The 305-048 variant specifically addresses needs for higher pin counts in a compact vertical form factor.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or flange configurations. Verify compatibility with existing polarizing key requirements before substituting.
