305-042-555-203

Edgeboard Connectors Overview

The EDAC Inc. 305-042-555-203 is a standard card edge connector from the 305 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 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts featuring gold plating, it supports a current rating of 5 A. The housing is made of green thermoplastic polyester, ensuring durability across an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design accommodates non-specified card edge PCBs for reliable signal transmission.
• Gold-plated copper alloy contacts provide corrosion resistance and stable electrical performance over time.
• Low-profile insulator body facilitates compact panel mounting while maintaining structural integrity.

Edgeboard Connectors Applications

• Industrial control systems requiring robust vertical interconnects
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation panels

Edgeboard Connectors Procurement Notes

Verify that the specific suffix matches the required termination style and flange configuration for your assembly. Confirm RoHS compliance status if restricted substances are prohibited in your manufacturing process. Ensure the PCB thickness falls within the specified acceptance range to guarantee proper contact engagement. Cross-reference the ordering guide to validate pin count and row alignment against your schematic requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is necessary for high-density signal routing in vertical panel applications. The 3.96 mm pitch allows for broader trace spacing compared to finer pitches, reducing manufacturing complexity. Consider the 5 A current rating for power distribution needs alongside signal lines. The thermoplastic insulation offers good dielectric strength for general electronic environments.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and termination options to suit different board designs. The 305-042 variant specifically provides a mid-range density solution, balancing connectivity needs with physical footprint constraints in standard enclosure formats.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical positioning but different termination styles, such as 305-042-520-202 or 305-042-500-504. Verify that any replacement maintains the same 0.156 inch pitch and 0.062 inch board thickness compatibility to ensure mechanical fit without redesigning the host panel.
