305-046-521-503

Edgeboard Connectors Overview

The EDAC Inc. 305-046-521-503 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 46 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts featuring gold plating, it ensures reliable signal transmission. The housing utilizes a low-profile thermoplastic insulator body, suitable for vertical panel mounting configurations.

• Consumer electronics mainboard interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and material specifications, as variations exist within the 305 series. Confirm RoHS compliance status against current regulatory requirements before finalizing procurement. Ensure the selected variant matches the required PCB thickness tolerance of 0.062 inches. Cross-reference the manufacturer's latest datasheet to validate availability and lead times, as distribution channels may vary by region.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection with 46 positions is required. Verify that the target PCB thickness aligns with the 0.062-inch specification to ensure proper mechanical retention. Consider the vertical panel mounting requirement for chassis integration. Evaluate the need for gold plating durability in high-cycle insertion environments compared to alternative finishes.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial applications. The series offers various position counts and mounting styles. The 305-046-521-503 specifically addresses the need for higher-density dual-edge connections with robust mechanical stability and reliable electrical performance in standard operating temperature ranges.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pin counts and spacing, such as the 305-046-521-507. Verify mechanical dimensions and electrical ratings before substitution. Alternative series like 387 or 970 offer different form factors but require full re-evaluation of mounting and interface compatibility.
