Overview
The EDAC Inc. 306-033-400-178 is a standard card edge connector designed for panel mounting applications. It features a single central row with 33 positions and a pitch of 0.156 inches (3.96 mm). The connector utilizes tin-plated copper alloy contacts and a green thermoplastic polyester housing. It supports a maximum operating temperature of +105°C and a minimum of -40°C, with an insulation resistance of 5 GOhms.
Feature Summary
- Single central row configuration for dual-edge card insertion
- Panel mount installation style with vertical orientation
- Tin-plated copper alloy contacts for reliable signal transmission
Applications
- Industrial control systems requiring robust interconnects
- Communication equipment board connections
- Consumer electronics module interfaces
Procurement Notes
Verify the specific contact plating finish against project requirements, as distributor listings may vary between tin and gold finishes for this part number. Confirm that the single-row central contact design aligns with the target PCB card edge specifications. Ensure the panel mount hole pattern matches the mechanical drawing before finalizing procurement orders to avoid integration issues.
Selection Notes
Select this component when a single-row, 33-position interface is required for vertical panel mounting. The 0.156-inch pitch accommodates standard double-sided card edges. Consider the thermal rating of +105°C for environments exceeding typical consumer limits. Verify compatibility with the target PCB thickness range to ensure proper contact engagement and mechanical stability during operation.
Part Context
This connector belongs to the EDAC 306 series, which specializes in standard card edge solutions. The series offers various position counts and mounting styles tailored for industrial and commercial applications. The 306-033-400-178 specifically addresses needs for moderate-density connections with durable thermoplastic housing materials suitable for repeated mating cycles.
Replacement Considerations
Direct substitutes include other EDAC 306 series parts with identical 33-position single-row configurations. Cross-reference pinout and mechanical dimensions carefully when considering alternative manufacturers. Ensure any replacement maintains the same 0.156-inch pitch and panel mount orientation to preserve existing enclosure designs.
