305-058-555-278

Edgeboard Connectors Overview

The EDAC 305-058-555-278 is a standard card edge connector from the 305 series, designed for dual-edge female connections. It features 58 positions arranged in two rows with a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Constructed with copper alloy contacts featuring gold plating, it supports a current rating of 5 A and an insulation resistance of 5 GOhms. The thermoplastic housing allows for vertical panel mounting, operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, termination style, and mounting hardware requirements. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm RoHS compliance status if required by project specifications. Cross-reference the part number with authorized distributors to validate availability and lead times before finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 58 positions is required for vertical panel installation. The 3.96 mm pitch suits applications needing moderate density without excessive miniaturization. Verify that the 5 A current rating meets the electrical load requirements of the connected circuitry. Ensure the thermoplastic housing material aligns with environmental constraints such as temperature exposure and chemical resistance.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various configurations for card edge applications. The series is characterized by its standardized dimensions and reliable performance in industrial environments. Similar parts in the series vary primarily in position count and mounting options, sharing common electrical characteristics and material compositions.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series variants with identical 58-position layouts and 3.96 mm pitch. Verify mechanical fit and electrical ratings before substitution. Generic replacements must match the dual-edge female interface and vertical mounting style to ensure proper integration.
