RBC70DCMI

Edgeboard Connectors Overview

The RBC70DCMI is a dual female card edge connector manufactured by Sullins Connector Solutions. It features 140 positions arranged in two rows of 70 contacts with a 0.100 inch (2.54 mm) pitch. The connector utilizes phosphor bronze clip spring contacts with a gold plating thickness of 10.0 µin (0.25 µm). Designed for through-hole, right-angle installation, it accepts cards up to 0.062 inches thick. The housing is made of polybutylene terephthalate (PBT) and is colored blue. It operates within a temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual female configuration with 140 total contact positions

• Gold-plated phosphor bronze clip spring contacts for reliable signal transmission
• Polybutylene terephthalate (PBT) insulation material

Edgeboard Connectors Applications

• High-density circuit board interconnections
• Industrial control system backplanes
• Telecommunications equipment interfaces
• Consumer electronics module connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against manufacturer documentation to ensure correct flange and termination specifications. Confirm that the required gold plating thickness meets application standards. Check RoHS compliance status if restricted substances are prohibited. Validate the operating temperature range against environmental conditions. Ensure the card edge thickness matches the connector's design limits.

Edgeboard Connectors Selection Notes

Select this model when a dual-sided female interface with a 0.100-inch pitch is required. Consider the right-angle through-hole mounting style for space-constrained layouts. Evaluate the PBT insulation properties for thermal stability. Compare contact plating thickness requirements against environmental exposure levels. Assess mechanical retention needs relative to the flange design options available in the series.

Edgeboard Connectors Part Context

This component belongs to the RBC70 series of card edge connectors from Sullins Connector Solutions. The series offers various configurations differing by pitch, flange type, and termination method. The RBC70DCMI specifically denotes a dual female variant with a 0.100-inch pitch and standard flange characteristics. It serves as a robust solution for high-pin-count applications requiring durable electrical connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes include RBC70DCMT and RBC70DCMI-S288, which share similar electrical and mechanical specifications. Verify compatibility regarding flange threading and termination style before substitution. Cross-reference datasheets to confirm identical pitch and contact count. Ensure that any alternative part maintains the same insulation material and temperature rating.
