746-030-553-101

Edgeboard Connectors Overview

The EDAC Inc. 746-030-553-101 is a standard card edge connector from the 746 Series, designed for press-fit installation onto printed circuit boards. It features a single row of 30 female contacts with a 0.125-inch (3.18mm) pitch. The contacts are constructed from copper alloy and finished with gold plating to ensure reliable signal transmission. This component supports wire wrap termination methods and is rated for an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Press-fit mounting technology for secure board attachment
• Single-row female contact configuration
• Gold-plated copper alloy contacts for conductivity
• Wire wrap termination capability

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• General-purpose electronic assemblies needing press-fit stability

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current 746 Series Ordering Guide to confirm exact pin count and termination style. Ensure that the target PCB design accommodates the required press-fit hole dimensions and spacing. Confirm compliance with RoHS3 and REACH regulations if environmental standards are mandatory for the final assembly. Cross-reference the part number with official distributor catalogs to validate current availability status.

Edgeboard Connectors Selection Notes

Select this model when a single-row interface with 30 positions is required for press-fit applications. The 0.125-inch pitch is suitable for standard card edge thicknesses. Consider the wire wrap termination option if through-hole wiring is preferred over soldering. Evaluate the thermal rating of -40°C to +105°C against the operational environment of the target system to ensure long-term reliability under varying temperature conditions.

Edgeboard Connectors Part Context

This component belongs to the EDAC 746 Series Ultra-Mate line, which specializes in high-reliability card edge connectors. The series offers various configurations including single and dual rows with different pin counts. The 746-030-553-101 specifically addresses the need for a 30-position single-row solution using press-fit technology, distinguishing it from surface-mount or through-hole solder variants within the broader product family.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 746 Series cross-reference documentation for verified substitute part numbers. Ensure any replacement maintains the same 30-pin count, 0.125-inch pitch, and press-fit mounting style. Verify that alternative components support wire wrap termination and meet the same electrical and thermal specifications.
