306-012-420-103

Edgeboard Connectors Overview

The EDAC Inc. 306-012-420-103 is a dual-sided card edge connector from the 306 series, designed for panel mount applications with through-hole termination. It features 24 positions arranged in two rows of twelve, utilizing a 0.156-inch (3.96mm) pitch. The connector employs female cantilever contacts with tin plating and is housed in green thermoplastic polyester insulation. It supports board thicknesses ranging from 0.054 to 0.070 inches and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 306 Series Ordering Guide to ensure correct pin count, contact plating, and orientation match. Confirm that the target PCB design accommodates the required 0.156-inch pitch and panel mounting hole specifications. Cross-reference the RoHS compliance status and moisture sensitivity level requirements with project standards before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-pitch 3.96mm interface is required for double-sided card edge applications. The tin-plated contacts offer standard conductivity suitable for general-purpose signaling. Ensure the mating card thickness falls within the specified 1.37mm to 1.78mm range to guarantee proper mechanical retention and electrical performance without excessive stress on the contacts.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 series, which specializes in card edge and rack & panel connectors. The series is widely utilized in computing, storage, medical, and aerospace sectors.
