306-022-421-178

Overview

The EDAC Inc. 306-022-421-178 is a standard card edge connector receptacle from the 306 Series, designed for single-row applications. It features 22 positions with a contact spacing of 3.96 mm (0.156 inches). The component utilizes P.C. tail type contacts with tin plating and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). It operates within a temperature range of -40°C to +105°C.

Feature Summary

• Single centreline row configuration with low profile insulator body
• Accepts nominal 0.062 inch thick printed circuit boards
• Tin-plated P.C. tail type contacts for termination

Applications

• Single-row card edge interconnections
• Low profile electronic assemblies
• Industrial control panel interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm contact plating and material specifications. Ensure the selected variant matches the required board thickness tolerance and operating temperature range for the intended application environment.

Selection Notes

Select this component when a single-row connection with 3.96 mm spacing is required. Confirm that the tin-plated contacts meet the environmental requirements, as gold plating options may be available in other variants within the same series for higher corrosion resistance.

Part Context

This part belongs to the EDAC 306 Series, which provides standard card edge connectors with 0.156-inch contact spacing. The series offers various position counts and mounting styles, utilizing thermoplastic polyester insulators and copper alloy contacts for reliable signal transmission.

Replacement Considerations

Compatible substitutes include other EDAC 306 series parts with matching 22-position single-row configurations and identical 3.96 mm pitch. Verify mechanical fit and electrical ratings before substitution.
