306-032-520-178

Overview

The EDAC Inc. 306-032-520-178 is a standard card edge connector from the 306 series, designed for through-hole mounting with a straight orientation. It features a dual female configuration with 64 positions (9 rows of 7 contacts) and a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a thermoplastic polyester insulator. It supports board thicknesses ranging from 1.37 mm to 1.78 mm and operates within a temperature range of -40°C to 105°C.

Feature Summary

• Dual female contact configuration for reliable card edge interface
• Gold-plated copper alloy contacts ensure durable electrical performance
• Thermoplastic polyester housing provides high-temperature resistance
• Through-hole solder termination with straight mounting style

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects

• Automotive electronic control units

Procurement Notes

Verify the specific suffix codes against the official EDAC datasheet to confirm exact pin count, plating thickness, and flange options. Ensure compatibility with the target PCB board thickness specifications before procurement. Confirm RoHS compliance status if required by project regulations. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current availability and lead times.

Selection Notes

Select this component when a high-density, double-sided card edge connection is required with a 3.96 mm pitch. The 306 series offers robust mechanical stability suitable for industrial environments. Consider the through-hole mounting requirement and straight orientation during PCB layout design. Verify that the operating temperature range meets the application's thermal demands.

Part Context

This connector belongs to the EDAC 306 series, which provides various mounting styles and contact configurations. The series is known for its reliability in demanding applications. The 306-032-520-178 variant specifically addresses needs for 64-position dual-side connections. It complements other components in systems requiring secure, high-current data transmission interfaces.

Replacement Considerations

Direct substitutes may include other EDAC 306 series connectors with matching pitch and position counts. Verify equivalent specifications from manufacturers like TE Connectivity or Molex if cross-brand replacement is necessary. Ensure identical mechanical dimensions and electrical ratings are maintained.
