305-034-521-501

Edgeboard Connectors Overview

The EDAC Inc. 305-034-521-501 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 34 positions with a 0.156-inch (3.96 mm) pitch and supports a maximum current rating of 5 A. The connector utilizes gold-plated copper alloy contacts with a thickness of 10.0 µin (0.25 µm) and half-beam contact types. It is constructed with a green thermoplastic polyester insulator and accepts PCB thicknesses between 0.054 and 0.070 inches (1.37–1.78 mm). Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to confirm exact pin count, termination style, and plating specifications. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm. Confirm that the required current rating of 5 A aligns with the application's electrical load requirements before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge interface with a 3.96 mm pitch is required. The 34-position configuration suits applications needing moderate I/O density. Verify that the panel mount or through-hole installation method matches the mechanical assembly constraints. Ensure the operating temperature range of -40°C to +105°C meets environmental demands.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-034-521-501 specifically denotes a 34-position dual-edge variant with gold contacts and a thermoplastic body, intended for general-purpose electronic interconnections requiring robust mechanical retention.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with identical pitch and position counts. Cross-reference compatible parts from other manufacturers only if they match the 0.156-inch pitch and dual-edge form factor precisely.
