Overview
The EDAC Inc. model 306-033-421-178 is a standard card edge connector from the 306 series, designed for panel mount installation. It features dual female contacts with a 0.156-inch (3.96mm) pitch and accommodates 66 positions across two rows. The connector utilizes gold-plated copper alloy terminals and a green thermoplastic polyester insulator. It supports PCB thicknesses ranging from 0.054 to 0.070 inches and operates within a temperature range of -40°C to +105°C.
Feature Summary
- Dual row configuration with 66 total positions for high-density interconnection
- Gold-plated copper alloy cantilever contacts ensure reliable signal transmission
- Panel mount design with vertical orientation for secure board integration
Applications
- Industrial control systems requiring robust panel-mounted connections
- Communication equipment utilizing standard card edge interfaces
- Consumer electronics assemblies needing durable dual-row connectors
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to confirm contact plating and termination style. Ensure the target printed circuit board thickness falls within the specified 0.054 to 0.070 inch range for proper mechanical engagement. Confirm RoHS compliance status if required by project specifications before finalizing procurement orders.
Selection Notes
Select this component when a dual-row, panel-mount card edge connector is required for applications demanding high durability. The 3.96mm pitch allows for broader trace spacing compared to finer pitches. Verify that the housing material and operating temperature range meet the environmental constraints of the intended deployment scenario.
Part Context
This part belongs to the EDAC 306 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and mounting styles, providing flexibility for different board densities. The 306-033 variant specifically addresses needs for higher pin counts in a dual-row format.
Replacement Considerations
Direct substitutes include other EDAC 306 series parts with matching 66-position dual-row configurations. Cross-reference dimensions such as the 3.96mm pitch and overall height to ensure mechanical compatibility. Verify that alternative components maintain similar electrical ratings and material compositions for equivalent performance.
