306-018-421-168

Edgeboard Connectors Overview

The EDAC Inc. model 306-018-421-168 is a standard card edge connector from the 306 series, designed for panel mount installation with a vertical orientation. It features a dual female configuration with 36 total positions arranged in two rows of 18 contacts each. The connector utilizes a 0.156-inch (3.96 mm) pitch and accepts board thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). Contact plating is tin, and the termination type is solder pin. The insulating material is thermoplastic polyester, rated for operation between -40°C and +105°C.

Edgeboard Connectors Feature Summary

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 306 Series Ordering Guide to ensure correct contact plating and terminal style. Confirm that the target printed circuit board thickness falls within the specified 1.37 mm to 1.78 mm range. Check RoHS compliance status if required by project specifications. Ensure panel cutout dimensions match the flange specifications provided in the mechanical drawings.

Edgeboard Connectors Selection Notes

Select this component when a 3.96 mm pitch card edge connector is required for panel-mounted applications. The dual-row female configuration supports high-density signal routing. Verify compatibility with the mating card's edge conductor layout. Consider the operating temperature range of -40°C to +105°C for environmental suitability. Compare against other 306 series variants if different contact counts or plating materials are needed.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 Series of standard card edge connectors. The series offers various position counts and mounting styles. The 306-018-421-168 specifically denotes a 36-position dual-row variant with tin-plated contacts and solder pin termination. It is distinct from the 302 series which uses a 1.27 mm pitch.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and form factor but different position counts, such as 306-018-421-164 or 306-018-421-166. Cross-series replacement requires matching the 3.96 mm pitch and dual-row configuration.
