306-021-420-104

Overview

The EDAC Inc. 306-021-420-104 is a standard card edge connector designed for panel mount applications. It features a dual female configuration with 42 positions and a 3.96 mm (0.156 inch) contact spacing. The connector utilizes gold-plated copper alloy contacts and solder pin termination. It accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The insulator body is constructed from thermoplastic polyester, providing a low-profile design suitable for vertical installation.

Feature Summary

• Dual female card edge connector architecture
• Gold-plated copper alloy contact system
• Low-profile thermoplastic polyester insulator
• Vertical panel mount installation style

Applications

• Industrial control systems requiring robust board-to-board connectivity
• Telecommunications equipment interfaces
• Test and measurement instrumentation panels
• Automotive electronics assemblies

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required board thickness and contact plating specifications. Confirm that the 42-position dual row configuration aligns with the target PCB footprint. Check RoHS compliance status against project requirements. Ensure the vertical mounting orientation matches the mechanical enclosure constraints before finalizing procurement orders.

Selection Notes

Select this component when a dual-sided connection is required for a 1.57 mm thick PCB. The 3.96 mm pitch offers a balance between density and ease of assembly. Gold plating ensures reliable signal transmission in environments prone to oxidation. Verify that the panel mount hole pattern matches the existing chassis design to avoid mechanical integration issues during production.

Part Context

This part belongs to the EDAC 306 series, which specializes in standard card edge connectors. The series provides various position counts and mounting styles to support diverse electronic packaging needs. The 306-021 variant specifically addresses applications requiring a 42-contact interface with high durability and consistent electrical performance across industrial temperature ranges.

Replacement Considerations

Cross-reference with other EDAC 306 series parts for alternative position counts. Verify mechanical dimensions against competitors like Glenair or Amphenol if sourcing alternatives. Ensure that any substitute maintains the same 3.96 mm pitch and 1.57 mm board thickness tolerance to guarantee fit.
