305-020-555-258

Edgeboard Connectors Overview

The EDAC Inc. model 305-020-555-258 is a standard card edge connector designed for dual-edge PCB insertion. It features 20 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Contacts are constructed from copper alloy and finished with gold plating to ensure reliable signal transmission. The connector utilizes a solder pin termination method and is rated for a current capacity of 5 A.

Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm availability in your region, as distribution status may vary by location. Ensure that the required board thickness matches the 1.57 mm specification before ordering. Confirm that the solder pin termination type aligns with your assembly process capabilities. Cross-reference the 20-position count and dual-row layout with your design requirements to prevent mechanical mismatch during integration.

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 5 A current rating and gold-plated contacts make it suitable for applications demanding stable electrical performance. Consider the low-profile design if space constraints exist within the enclosure. Verify compatibility with the target PCB thickness of 1.57 mm to ensure proper mechanical fit and contact engagement.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which provides a range of standard card edge solutions. The series offers various position counts and termination options to accommodate different board densities. The 305-020-555-258 variant specifically addresses needs for moderate density connections with robust contact materials. It serves as a reliable interface between modular circuit boards and host systems in professional electronic assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 20-position count, 3.96 mm pitch, dual-row layout, and 1.57 mm board thickness. Verify that any alternative maintains the same solder pin termination and vertical mounting orientation. Ensure the replacement supports the 5 A current rating and uses compatible contact materials for equivalent performance.
