305-042-521-504

Edgeboard Connectors Overview

The EDAC Inc. 305-042-521-504 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 42 positions in a dual-row configuration with a 3.96 mm (0.156 inch) contact spacing and 3.56 mm row spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Contacts are made of copper alloy with gold plating, rated for 5 A current. The housing is constructed from thermoplastic polyester, offering an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to ensure correct contact plating and housing color specifications. Confirm that the target application supports the specified 1.57 mm PCB thickness and panel mounting constraints. Check RoHS compliance status against current regulatory requirements for the destination market. Ensure sourcing channels provide original manufacturer documentation for quality assurance.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 42-position interface is required with a 3.96 mm pitch. Consider the vertical panel mount style for space-constrained enclosures. Evaluate the 5 A current rating against peak load requirements. Compare against other 305 series variants if different position counts or single-row configurations are needed for alternative designs.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which provides standard card edge solutions for various industrial and commercial applications. The series offers multiple position counts and row configurations to accommodate diverse PCB layouts. Components in this line typically feature durable thermoplastic housings and gold-plated contacts for long-term reliability in demanding environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-048-520-512 and 305-040-520-268, though these differ in position count. Verify mechanical compatibility and pinout alignment before substitution. Alternative series may require adapter solutions or redesign of the mating PCB footprint.
