395-054-542-203

Edgeboard Connectors Overview

The EDAC Inc. 395-054-542-203 is a standard card edge connector featuring 54 positions arranged in a dual-row configuration. It utilizes a 0.100 inch (2.54mm) pitch and accepts circuit boards with thicknesses ranging from 0.054 to 0.070 inches. The connector employs female, cantilever contacts with gold plating for reliable signal transmission. Designed for vertical through-hole mounting, it includes flanges with top-mounting openings and M3 threaded inserts for secure installation. The housing is constructed from black thermoplastic polyester, ensuring durability across an operating temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates double-sided circuit board connections
• Gold-plated cantilever contacts ensure consistent electrical performance and corrosion resistance
• Integrated flanges with M3 threaded inserts provide robust mechanical stability during installation

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Automotive electronic module interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact physical dimensions and termination style. Ensure compatibility with target PCB thickness specifications before ordering. Confirm RoHS compliance status if required by project regulations. Cross-reference manufacturer part numbers with distributor listings to avoid sourcing errors.

Edgeboard Connectors Selection Notes

Select this component when dual-sided board connectivity is required within a single connector footprint. The vertical orientation suits panel or chassis mounting applications. Verify that the 0.100-inch pitch aligns with existing board layout constraints. Consider the thermal rating limits for high-temperature operational environments.

Edgeboard Connectors Part Context

This part belongs to the EDAC 395 series of standard card edge connectors. The series offers various position counts and row configurations to support diverse interface requirements. Components in this family share common mounting styles and material properties while differing in pin count and specific mechanical features.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 395 series parts with matching 54-position dual-edge specifications. Verify equivalent pitch and board thickness tolerances when considering alternative manufacturers. Ensure flange mounting hole patterns remain compatible with existing hardware.
