306-030-420-104

Overview

The EDAC Inc. 306-030-420-104 is a standard card edge connector designed for panel mount applications with a vertical orientation. It features a single row of 30 female contacts spaced at 3.96 mm (0.156 inches). The connector accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Contacts are constructed from copper alloy and finished with tin plating to ensure reliable signal transmission. The insulating body is made of thermoplastic polyester, providing durability in demanding environments. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C.

Feature Summary

• Vertical panel mount receptacle configuration for secure board insertion
• Single centerline row design accepting specified PCB thickness
• Tin-plated copper alloy contacts for corrosion resistance
• Thermoplastic polyester housing for thermal stability

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Automotive electronic sub-systems

Procurement Notes

Verify the specific contact finish and row configuration against project requirements before ordering. Confirm that the target PCB thickness falls within the accepted tolerance range of 1.37 mm to 1.78 mm. Ensure compatibility with mating card edge specifications. Check regional availability as distribution status may vary by location. Validate RoHS compliance documentation if required for the final assembly.

Selection Notes

Select this component when a single-row, vertically mounted card edge interface is required. The 3.96 mm pitch suits applications needing robust mechanical retention. Consider the tin finish for general-purpose use rather than high-frequency or gold-plated variants. Verify that the 5 A current rating meets the electrical load requirements. Ensure the panel mounting style aligns with the chassis design constraints.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series offers various configurations including different row counts, pitches, and termination styles. The 306-030-420-104 specifically denotes a 30-position, single-row variant with tin plating. It is distinct from dual-row models like the 306-043 series or gold-plated variants such as the 306-030-521-107.

Replacement Considerations

Direct substitutes include other EDAC 306 series parts with identical 30 positions, 3.96 mm pitch, and single-row layout. Verify pin count and PCB thickness compatibility when cross-referencing. Alternative manufacturers may offer similar specs but require mechanical verification.
