306-018-421-158

Edgeboard Connectors Overview

The EDAC Inc. 306-018-421-158 is a dual female card edge connector with 36 positions arranged in two rows of 18 contacts each. It features a 0.156-inch (3.96mm) pitch and utilizes wire wrap termination for secure board mounting. The connector accommodates card thicknesses between 0.054 inches and 0.070 inches. Constructed with a green thermoplastic insulator, it offers gold plating on the mating area and tin plating on the tails over nickel underplating. Rated for 5 amps with a maximum contact resistance of 10 milliohms, it operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 0.156-inch pitch and dual-row configuration before ordering. Confirm compatibility with the target PCB layout regarding wire wrap termination spacing. Ensure the selected variant meets the necessary current rating and environmental specifications for the intended application environment. Cross-reference manufacturer documentation for any recent updates to compliance standards or material compositions.

Edgeboard Connectors Selection Notes

Choose this component when a dual-sided card edge interface with a 0.156-inch spacing is required. The wire wrap termination style is suitable for applications where reworkability and mechanical security are prioritized over surface mount convenience. Consider the operating temperature range and current rating to ensure performance reliability under load. Verify that the insulator color and physical dimensions align with existing chassis or panel constraints.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 306 series, designed for general-purpose card edge applications. The series offers various pin counts and pitch options to accommodate different system architectures. As an active component, it supports legacy designs while maintaining availability for new production runs. The dual female configuration allows for mating with male pins on the opposing card or backplane structure.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 36-position count, dual-row layout, and 0.156-inch pitch. Wire wrap termination compatibility is critical for mechanical interchangeability. Inspect alternative vendors for identical plating specifications and thermal ratings to ensure equivalent performance characteristics without redesigning the host assembly.
