302-070-221-201

Edgeboard Connectors Overview

The EDAC Inc. 302-070-221-201 is a card edge connector from the 302 Series, designed for dual-edge board applications. It features 70 positions with a 0.050" (1.27mm) contact spacing and four terminal rows. The connector utilizes gold flash-plated cantilever contacts housed in black polyamide (PA66) insulation. It supports PCB thicknesses between 0.051" and 0.071" (1.30mm to 1.80mm). Rated for operation from -55°C to 85°C, it employs a solder termination method and is suitable for non-specified dual-edge cards.

Edgeboard Connectors Feature Summary

• Dual-edge receptacle design accommodating non-specified card types
• Gold flash plated cantilever contacts for reliable signal transmission
• Black polyamide (PA66) insulator body for thermal stability
• Solder termination for secure PCB mounting

Edgeboard Connectors Applications

• Industrial control systems requiring high-density I/O
• Telecommunications equipment backplanes
• Computing hardware memory or expansion modules
• Test and measurement instrumentation interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact count and plating specification. Confirm the package quantity aligns with production needs, as standard packaging may vary. Ensure the supplier provides valid RoHS3 compliance documentation. Cross-reference the MSL rating of 1 to confirm storage and handling requirements are met for your facility's standards before finalizing the purchase order.

Edgeboard Connectors Selection Notes

Select this component when a 0.050" pitch dual-edge connector is required for high-pin-count applications. The 70-position configuration offers significant density within the 302 series footprint. Verify that the target PCB thickness falls within the 1.30mm to 1.80mm range to ensure proper contact engagement. Consider the operating temperature range of -55°C to 85°C against environmental conditions. The gold flash plating is suitable for general-purpose signals where corrosion resistance is needed.

Edgeboard Connectors Part Context

This part belongs to the EDAC 302 Series, which specializes in .050" (1.27mm) spaced card edge connectors. The series is characterized by its versatility in providing various position counts and mounting options for dual-edge boards. The 302-070-221-201 represents a high-pin-count variant within this family, utilizing standard black PA66 insulation and gold-plated contacts for robust performance in demanding electronic assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical spacing and pin counts, such as the 302-070-221-201 variants with different mounting styles. For cross-referencing, verify that any alternative maintains the 0.050" pitch and dual-edge compatibility. Ensure the replacement part supports the same PCB thickness range and termination method to guarantee mechanical fit and electrical continuity without redesigning the host board.
