306-023-420-158

Overview

The EDAC Inc. 306-023-420-158 is a standard card edge connector from the 306 series, designed for reliable signal transmission in electronic assemblies. This receptacle features a dual-edge female configuration with 46 positions arranged in a single row. The contact spacing is 0.156 inches (3.96mm), accommodating printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The unit utilizes tin-plated copper alloy contacts and a green thermoplastic polyester insulator body. It supports panel mount installation via through-hole solder termination and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Dual-edge female contact configuration ensures secure mating with double-sided card edge PCBs.
• Low-profile insulator body design facilitates compact integration into dense electronic enclosures.
• Through-hole solder termination provides robust mechanical stability and electrical connectivity.
• Panel mount style allows for fixed positioning and secure attachment to chassis or backplanes.

Applications

• Industrial control systems requiring durable interconnect solutions
• Medical equipment utilizing EDAC medical interconnect components
• Agricultural technology hardware operating in harsh environments
• General-purpose electronic assemblies needing standard card edge interfaces

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official EDAC documentation. Confirm that the specific ordering suffix matches the required contact plating and flange characteristics. Ensure compatibility with target PCB thickness and mounting constraints before finalizing acquisition. Check current supply status as availability may vary across distribution channels.

Selection Notes

Select this model when a dual-edge female connector with 0.156-inch spacing is required for 1.57mm thick boards. Consider the tin-plated contacts for cost-effective applications where high corrosion resistance is not critical. Evaluate the panel mount requirement against available space and ensure the operating temperature range meets system environmental specifications.

Part Context

This component belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and termination options. The 306-023 variant specifically denotes a 46-position configuration. Related models include 306-023-420-112 and 306-023-421-102, which share similar form factors but differ in contact plating or flange features.

Replacement Considerations

Potential substitutes include EDAC 306-023-420-112 for identical mechanical specs with different plating. Verify pin count, spacing, and mounting style match exactly. Cross-reference datasheets for thermal and electrical ratings to ensure functional equivalence without redesigning the host board.
