396-088-541-204

Edgeboard Connectors Overview

The EDAC Inc. 396-088-541-204 is a dual-sided female card edge connector designed for board-to-board interconnection. It features 88 positions with a 0.125-inch (3.18mm) pitch and a 0.140-inch (3.56mm) row spacing. The connector utilizes cantilever contacts with gold plating over a copper alloy base, ensuring reliable signal transmission. It supports PCB thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). The housing is black thermoplastic polyester, rated for operation between -40°C and +105°C. Mounting is achieved via flanges with 0.156-inch diameter holes.

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to ensure correct pin count and termination style. Confirm RoHS compliance status matches project requirements. Check for lead time variations as distribution availability may fluctuate. Ensure PCB stack-up accommodates the specified card thickness range. Validate mating connector compatibility before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this model when a high-density 88-position connection is required with standard 0.125-inch spacing. Consider the cantilever contact type for ease of insertion and removal during maintenance. Evaluate thermal ratings against operational environments exceeding standard limits. Compare physical dimensions against available PCB real estate constraints. Assess mechanical retention needs for flange-based mounting solutions.
