305-034-521-201

Edgeboard Connectors Overview

The EDAC Inc. 305-034-521-201 is a standard card edge connector from the 305 series, designed for dual-edge board mating. It features 34 positions with a pitch of 3.96 mm (0.156 inches) and supports a PCB thickness of 1.57 mm. The connector utilizes gold-plated copper alloy contacts rated for 5 A current. It employs a solder pin termination type and is constructed with a thermoplastic polyester housing. This vertical panel mount header provides reliable electrical interconnection for edgeboard applications.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and housing color variations, as these attributes may differ across production batches. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that the selected variant matches the required PCB thickness tolerance of 1.57 mm to guarantee proper mechanical fit and electrical performance during assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided card edge interface with a 3.96 mm pitch is required. The 34-position count suits moderate-density signal routing needs. Verify that the vertical panel mount style aligns with the enclosure design constraints. Consider the 5 A current rating for power distribution requirements and ensure the operating temperature range of -40 C to +105 C meets environmental specifications.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and mounting styles to accommodate different board densities. The 305-034-521-201 specifically addresses applications requiring dual-edge connectivity with high reliability standards, serving as a critical interface between circuit boards and chassis-mounted headers.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different suffixes for plating or material variations. Cross-series replacements require matching the 3.96 mm pitch and 1.57 mm board thickness. Verify compatibility with existing tooling and PCB footprints before transitioning to alternative manufacturers or modified part numbers.
