305-026-500-503

Edgeboard Connectors Overview

The EDAC Inc. 305-026-500-503 is a standard card edge connector from the 305 series, designed for dual female interface applications. It features 26 positions with a 0.156-inch (3.96 mm) pitch across two rows. The connector utilizes gold-plated copper alloy contacts and a thermoplastic housing, supporting a board thickness of 1.57 mm. Rated for 5 A current at up to 105°C, it employs vertical panel mounting with solder pin termination.

Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm compatibility with target PCB stack-up and mating card specifications. Ensure that the required current rating and temperature range align with the operational environment. Cross-reference the mounting style and termination type with the assembly process requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector is required for double-sided card edge applications. The 0.156-inch pitch and 26-position count define the electrical density. Consider the vertical panel mount orientation and solder pin termination method for mechanical integration. Verify that the thermoplastic housing material meets environmental exposure requirements for the intended deployment scenario.

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 to accommodate diverse electronic assembly needs. The 305-026-500-503 variant specifically addresses applications requiring a moderate density interface with robust mechanical retention and reliable electrical performance in industrial environments.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes within the same family. Verify dimensional tolerances and contact plating specifications when evaluating alternative sources. Ensure any replacement maintains the dual female configuration and compatible board thickness range.
