306-023-520-103

Overview

The EDAC Inc. 306-023-520-103 is a standard card edge connector from the 306 series, designed for panel mount applications. It features a dual female configuration with 46 positions arranged in a single centerline row. The connector utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm. Constructed with copper alloy contacts featuring gold plating and a thermoplastic insulator body, it supports a current rating of 5 A and offers an insulation resistance of 5 GOhms.

Feature Summary

• Dual female contact configuration for secure board insertion
• Low profile insulator body design for space-constrained panels
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Panel mount installation style with vertical orientation

Applications

• Industrial control panel interconnections
• Telecommunications equipment backplanes
• Test and measurement instrument interfaces
• Automotive electronic module connections

Procurement Notes

Verify the specific ordering suffix to confirm contact count, plating thickness, and insulator color variations within the 306 series. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the target PCB thickness aligns with the specified 1.57 mm nominal requirement for proper mechanical fit and electrical performance.

Selection Notes

Select this component when a dual-row female card edge interface is required for panel-mounted systems. The 3.96 mm pitch suits applications needing robust mechanical stability with moderate pin density. Consider the 5 A current rating and 5 GOhm insulation resistance for general-purpose industrial signals. Verify that the single centerline row layout matches the target PCB trace pattern before finalizing the design.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors, which are characterized by their low-profile thermoplastic bodies and panel-mount versatility. The series provides various position counts while maintaining consistent 3.96 mm spacing. The 306-023-520-103 specifically addresses needs for dual-sided connectivity in compact enclosures, offering a balance between mechanical durability and electrical reliability for standard industrial environments.

Replacement Considerations

Direct substitutes within the same series include parts like 306-023-520-101 or 306-023-520-178, depending on required plating thickness and color coding. Cross-series replacements require matching the 3.96 mm pitch and 1.57 mm board thickness constraints. Always verify that alternative components maintain the same dual female contact configuration and panel mount orientation to ensure mechanical compatibility.
