306-013-521-168

Edgeboard Connectors Overview

The EDAC Inc. 306-013-521-168 is a dual-edge female card edge connector designed for panel and through-hole mounting. It features 26 positions arranged in two rows with a 0.156-inch (3.96mm) contact spacing. The contacts are made of copper alloy with a gold finish, utilizing a cantilever spring design for reliable engagement. The housing is constructed from thermoplastic polyester and is green in color. It accepts card thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). The unit operates within a temperature range of -40°C to 105°C and includes flange features for top opening and threaded inserts.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current 306 Series Ordering Guide to confirm exact pin count and termination style. Ensure that the procurement documentation explicitly states compliance with RoHS3 and REACH regulations as required by project specifications. Confirm that the supplier provides valid traceability records for the gold plating thickness and material composition prior to finalizing the purchase order.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided card edge connection with 0.156-inch spacing is required for robust mechanical retention. The cantilever contact design offers superior vibration resistance compared to standard press-fit alternatives. Verify that the target PCB or card thickness falls within the specified 0.054 to 0.070-inch range to ensure proper mating force and electrical continuity without mechanical stress on the connector body.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 Series of card edge connectors, which are engineered for high-reliability applications requiring durable mechanical interfaces. The series utilizes a standardized footprint and mounting configuration, allowing for consistent design practices across various product lines. The 306 series is widely recognized in industrial and communication sectors for its balance of cost-effectiveness and long-term performance stability under harsh environmental conditions.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical spacing and position counts but different termination styles. Cross-series replacements require careful verification of flange dimensions and mounting hole patterns. Always validate that any alternative part maintains the same contact material properties and operating temperature range to ensure system reliability.
