305-042-555-503

Edgeboard Connectors Overview

The EDAC Inc. 305-042-555-503 is a standard card edge connector from the 305 series, designed for panel mounting with a vertical orientation. It features 42 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes female half-beam contacts made of copper alloy and finished with gold plating to ensure reliable signal transmission. It accepts non-specified dual-edge cards with thicknesses ranging from 1.37 mm to 1.78 mm. The housing is constructed from green thermoplastic polyester, providing insulation resistance of 5 GOhms and supporting a continuous current rating of 5 A across an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates non-specified PCBs with robust half-beam termination.
• Gold-plated copper alloy contacts provide durable electrical interfaces within a thermoplastic polyester housing.
• Panel-mount construction includes floating eyelets for secure installation and alignment.

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Automotive electronic module connections

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required flange and eyelet specifications, as variations exist within the 305 series. Confirm compliance with RoHS3 and REACH regulations prior to integration. Ensure the selected variant aligns with the intended panel thickness and mounting hardware requirements to maintain mechanical stability during operation.

Edgeboard Connectors Selection Notes

Select this component when a 42-position dual-row interface with a 3.96 mm pitch is required for vertical panel mounting. The 5 A current rating and wide temperature tolerance make it suitable for demanding environments. Verify compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm before finalizing the design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for high-reliability applications. The series offers various position counts and mounting options, utilizing consistent material standards such as thermoplastic polyester insulators and gold-plated contacts to ensure long-term performance in harsh conditions.

Edgeboard Connectors Replacement Considerations

The 305-042-520-202 serves as a comparable alternative within the same series, offering identical electrical parameters and positioning but differing in flange characteristics and eyelet style. Evaluate mechanical fitment constraints before substitution.
