302-048-621-201

Edgeboard Connectors Overview

The EDAC Inc. 302-048-621-201 is a standard card edge connector from the 302 Series, designed for dual-edge board applications. It features 48 positions with a 0.050" (1.27mm) contact spacing and a 0.200" (5.08mm) row spacing. The connector utilizes gold-plated contacts on a black polyamide (PA66) housing. It supports PCB thicknesses ranging from 0.051" to 0.071" (1.30mm to 1.80mm). This component employs a surface mount termination method and operates within a temperature range of -55°C to +85°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact finish and plating thickness specifications. Ensure the selected variant matches the required surface mount footprint and thermal profile capabilities. Cross-reference the RoHS compliance status with current regulatory requirements for the target market. Confirm that the package quantity aligns with production volume needs without relying on distributor stock estimates.

Edgeboard Connectors Selection Notes

Select this model when a low-profile, dual-edge connection is required for boards with thicknesses between 1.30mm and 1.80mm. The 1.27mm pitch suits high-density layouts where space is constrained. Verify compatibility with the mating card edge geometry and ensure the operating temperature range meets environmental conditions. Consider the surface mount orientation for optimal mechanical retention during reflow soldering processes.

Edgeboard Connectors Part Context

This component belongs to the EDAC 302 Series, which specializes in standard card edge connectors. The series offers various position counts and termination styles to accommodate diverse PCB design requirements. The 302-048-621-201 specifically addresses applications needing 48 channels with a fine 1.27mm pitch, providing a robust solution for compact electronic assemblies requiring reliable electrical connectivity.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 302-024-621-201 and 302-096-621-201, which share identical mechanical and electrical characteristics but differ in position count. Ensure any replacement maintains the 0.050" pitch and surface mount termination type to preserve board layout integrity.
