305-026-555-203

Edgeboard Connectors Overview

The EDAC Inc. 305-026-555-203 is a standard card edge connector from the 305 Series, designed for PCB mounting with a straight installation style. It features 26 positions arranged in a dual row configuration with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Contacts are constructed from copper alloy with gold plating, rated for 5 A current at +105°C maximum operating temperature.

Edgeboard Connectors Feature Summary

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure correct pin count, row configuration, and termination style match the design requirements. Confirm that the gold plating thickness and insulation material specifications align with environmental constraints such as operating temperature range and chemical resistance needs before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 3.96 mm pitch is required. Ensure the target PCB thickness falls within the specified acceptance range. Consider the straight mounting orientation and through-hole solder termination method during mechanical layout planning to maintain proper alignment and connection integrity.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors. The series offers various position counts and configurations, utilizing a consistent 3.96 mm contact spacing.
