ESC35DRTI-S734

Edgeboard Connectors Overview

The ESC35DRTI-S734 is a dual-edge card connector manufactured by Sullins Connector Solutions. It features 70 positions arranged in two rows of 35 contacts each, with a 0.100-inch (2.54mm) spacing. Designed for through-hole termination, the connector utilizes phosphor bronze full bellows contacts with a 10.0µin gold plating thickness. The housing is blue PBT material, rated for operation between -65°C and 125°C. It supports non-specified double-sided cards up to 0.062 inches thick and includes threaded 4-40 top-mount flange openings.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 70 total contact positions for high-density signal routing
• Full bellows contact design ensures reliable mating force and low contact resistance
• Gold-plated phosphor bronze terminals offer corrosion resistance and stable electrical performance
• Threaded mounting flanges facilitate secure panel installation and alignment

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify that the specific suffix matches the required flange type and insulation material before ordering. Confirm compatibility with the target PCB stack-up and card thickness specifications. Ensure storage conditions meet manufacturer guidelines to maintain terminal integrity. Cross-reference the RoHS compliance status with current regulatory requirements for the destination market. Validate mechanical dimensions against the official datasheet drawings prior to integration.

Edgeboard Connectors Selection Notes

Choose this model when a dual-edge interface with 70 positions is required for through-hole assembly. Select based on the need for threaded mounting options versus unthreaded variants. Consider the operating temperature range and insulation material properties for environmental suitability. Compare contact plating thickness requirements against application lifecycle needs. Evaluate board thickness constraints to ensure proper engagement depth.

Edgeboard Connectors Part Context

This component belongs to the ESC series of edge connectors from Sullins Connector Solutions. The series offers various configurations for single and double-sided card applications. Different suffixes denote variations in flange types, materials, and plating thicknesses. The ESC35 variant specifically addresses mid-range density requirements in industrial interconnect systems.

Edgeboard Connectors Replacement Considerations

Direct substitutes include HSC35DRTI and ASC35DRTI, which share similar form factors but differ in material or flange specifications. Verify mechanical fit and electrical parameters before swapping. Ensure alternative parts meet the same thermal and environmental ratings.
