307-021-457-108

Edgeboard Connectors Overview

The EDAC Inc. model 307-021-457-108 is a standard card edge connector from the 307 series, designed for dual-edge board insertion. It features 42 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.200 inches (5.08 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). It utilizes female contacts made of copper alloy with tin plating. The housing is constructed from green thermoplastic polyester. This header-style component supports panel mounting at a vertical angle and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required pin count and termination type before ordering. Confirm compatibility with the target PCB thickness of 0.062 inches to ensure proper mechanical fit. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the supplier provides official datasheets for accurate dimensional verification.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection with 42 positions is required. The 3.96 mm pitch suits applications needing robust signal routing across multiple rows. Consider the vertical panel mount style for fixed installations where space constraints favor low-profile designs. Verify that the tin-plated contacts meet the corrosion resistance requirements of the operating environment.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 307 series, which offers various configurations for card edge applications. The series is characterized by standardized dimensions and reliable performance in harsh environments. The 307-021-457-108 variant specifically addresses needs for higher density connections through its 42-position layout while maintaining the structural integrity typical of the line.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 307 series connectors with matching 42 positions and dual-edge specifications. Cross-reference part numbers such as 307-021-457-168 for similar form factors. Ensure any replacement maintains the same 0.156-inch pitch and 0.062-inch board thickness acceptance.
