305-042-521-501

Edgeboard Connectors Overview

The EDAC Inc. 305-042-521-501 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 42 positions with a 0.156-inch (3.96 mm) pitch and accepts PCB thicknesses between 0.054 and 0.070 inches (1.37 to 1.78 mm). The connector utilizes gold-plated copper alloy contacts with a 10.0 µin (0.25 µm) finish and half-bead contact types. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C. The housing is green thermoplastic polyester, and it employs vertical panel mount solder lug termination.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating thickness and housing color specifications. Ensure that the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper mechanical engagement. Confirm RoHS compliance status through the latest regulatory documentation provided by EDAC Inc. prior to final procurement authorization.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge connector with a 3.96 mm pitch is required for vertical panel mounting. The 42-position capacity suits applications needing moderate density without excessive footprint usage. Verify that the operating environment remains within the -40°C to +105°C thermal limits and that the 5 A current rating aligns with the circuit design requirements for long-term reliability.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are engineered for general-purpose industrial and commercial electronics. The series offers various position counts and mounting styles, providing flexibility for different board integration needs. As a dual-edge connector, it supports bidirectional signal routing across the board interface, enhancing connectivity options in compact system designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with identical 42-position dual-edge configurations, such as 305-042-520-504 or 305-042-520-268, provided they match the required pitch and termination style. Cross-brand replacements require careful verification of dimensional tolerances, contact geometry, and material compatibility to ensure functional equivalence.
