306-027-421-102

Overview

The EDAC Inc. 306-027-421-102 is a standard card edge connector receptacle from the 306 series. It features 54 positions arranged in a dual-edge configuration with a contact spacing of 0.156 inches (3.96 mm). The connector utilizes tin-plated copper alloy contacts and terminates via solder eyelets for panel mount installation. Designed for green thermoplastic polyester insulators, it accommodates PCB thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm) and operates within a temperature range of -40°C to 105°C.

Feature Summary

• Dual-edge female connector design accommodating specified PCB thickness ranges
• Solder eyelet termination method ensuring secure panel mount integration
• Tin-plated copper alloy contacts providing reliable electrical connectivity
• Green thermoplastic polyester insulator body for environmental stability

Applications

• Panel-mounted electronic assemblies requiring dual-edge board interfaces
• Industrial control systems utilizing standard card edge form factors
• Test and measurement equipment needing robust vertical interconnects

Procurement Notes

Verify component authenticity through authorized EDAC distributors or certified suppliers. Confirm RoHS compliance status and specific lot traceability requirements prior to acquisition. Ensure storage conditions maintain moisture sensitivity level integrity. Cross-reference ordering suffixes to validate exact plating and packaging specifications against current manufacturer documentation.

Selection Notes

Select this component when a dual-edge receptacle with 3.96 mm pitch is required for panel mounting applications. Verify that the target printed circuit board thickness falls within the 1.37 mm to 1.78 mm operational window. Ensure compatibility with tin-plated contact systems and solder eyelet termination processes. Confirm thermal operating limits align with the intended environmental conditions.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and termination styles tailored for diverse industrial and commercial electronics. The 306 series is characterized by its low-profile insulator bodies and standardized spacing options, facilitating widespread adoption in modular electronic hardware designs requiring reliable vertical connections.

Replacement Considerations

Direct substitutes include EDAC 306-027-421-168, which shares identical mechanical dimensions and contact configuration. Verify pin count, pitch, and termination type match exactly before substitution. Alternative series may require re-evaluation of mounting flanges and PCB thickness tolerances.
