305-048-555-203

Edgeboard Connectors Overview

The EDAC Inc. 305-048-555-203 is a standard card edge connector from the 305 series, designed for vertical panel mounting. It features 48 positions with a 0.156-inch (3.96 mm) contact spacing and a 0.140-inch (3.56 mm) row spacing. The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts that are gold-plated, it supports a current rating of 5 A. The insulator body is made of thermoplastic polyester, colored green, and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Vertical panel mount design with low-profile insulator body
• Gold-plated copper alloy contacts for reliable signal transmission
• Dual-edge female configuration compatible with non-specified cards

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement devices needing high-density interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to ensure correct pin configuration and plating specifications. Confirm compatibility with the target PCB thickness of 0.062 inches. Check for RoHS compliance status as per the latest manufacturer documentation before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 48 positions is required. Ensure the application environment stays within the -40°C to +105°C operating temperature range. Verify that the panel mounting style aligns with the mechanical design constraints of the enclosure.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and spacing options. The 305-048-555-203 specifically provides a 48-position layout suitable for applications requiring moderate density in a vertical form factor.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with different position counts or spacing. Cross-reference with other manufacturers' catalogs only if mechanical dimensions and electrical ratings match exactly.
