305-042-500-207

Edgeboard Connectors Overview

The EDAC Inc. 305-042-500-207 is a standard card edge connector header from the 305 series, designed for vertical panel mounting. 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). It utilizes gold-plated copper alloy contacts with a current rating of 5 A and employs a solder lug termination type.

Edgeboard Connectors Feature Summary

• Vertical panel mount design with low profile insulator body
• Gold-plated copper alloy contacts for reliable signal transmission
• Accepts standard 0.062 inch nominal thickness PCBs

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm termination style and plating thickness. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm that the 42-position count aligns with the circuit design requirements. Check RoHS compliance status if required by project specifications. Validate panel cutout dimensions against the manufacturer's dimensional drawing.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector is needed for vertical board insertion. The 3.96 mm pitch suits applications requiring wider spacing than standard 2.54 mm headers. Consider the 5 A current rating for power distribution needs. The solder lug termination requires appropriate panel mounting holes. Verify insulation material properties for high-temperature environments up to 105°C.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options. The 305-042 variant specifically provides 42 contacts in a dual-row configuration. Similar parts include the 305-048 and 305-038 models with different pin counts but identical pitch and form factor.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-042-520-202 and 305-042-500-504. Verify that alternative suffixes match the required termination type and plating specifications. Cross-reference dimensional drawings to ensure mechanical fit in existing panel cutouts.
