ESA36DTBD-S273

Edgeboard Connectors Overview

The ESA36DTBD-S273 is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 72 positions arranged in two rows with a 0.125-inch (3.18 mm) pitch. Designed for right-angle through-hole mounting, the connector utilizes phosphor bronze contacts with a gold finish over nickel. The insulator is constructed from polybutylene terephthalate (PBT), supporting mating PCB thicknesses of 0.093 inches or 0.125 inches. It operates within a temperature range of -65°C to 125°C and includes flush mount flange features.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with loop bellows contact type for secure board engagement
• Right-angle termination designed for standard through-hole soldering processes
• Gold-plated phosphor bronze contacts ensure reliable electrical conductivity and corrosion resistance
• Flush mount flange design allows for low-profile installation on printed circuit boards

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify that the specific suffix -S273 matches the required packaging and terminal configuration for your assembly line. Confirm that the mating PCB thickness aligns with the connector's specified tolerance for either 0.093-inch or 0.125-inch boards. Ensure that the right-angle orientation fits within the mechanical enclosure constraints. Check for RoHS compliance documentation if environmental regulations apply to your final product manufacturing process.

Edgeboard Connectors Selection Notes

Select this component when a high-contact-count interface is required in a compact footprint. The 0.125-inch pitch offers a balance between signal density and manufacturing ease compared to finer pitches. The right-angle form factor is ideal for stacking modules or directing cable exits perpendicular to the main board plane. Consider the PBT insulator material for its thermal stability and flame retardancy ratings during high-temperature soldering operations.

Edgeboard Connectors Part Context

This part belongs to the ESA series of card edge connectors from Sullins Connector Solutions. The series is characterized by robust mechanical design and standardized dimensions for interchangeability. The 'D' indicates a dual-edge connection, while 'B' specifies the right-angle termination style. This family is widely used in applications requiring durable, repeatable insertion cycles for removable electronic cards.

Edgeboard Connectors Replacement Considerations

Direct substitutes include models with identical pin counts and pitch, such as ESA36DTBT variants, provided the termination angle and flange features match. Verify that any alternative part maintains the same contact material and plating thickness to ensure equivalent electrical performance and mating durability.
