ESA22DRSI-S288

Edgeboard Connectors Overview

The ESA22DRSI-S288 is a female card edge connector manufactured by Sullins Connector Solutions. It features 44 contacts arranged in two rows with a 0.125-inch pitch. Designed for right-angle surface mount installation, the unit includes locking mechanisms to secure the connection. The contacts utilize gold over nickel termination and bellowed type styling to ensure reliable engagement. The insulator is constructed from polybutylene terephthalate (PBT), providing structural integrity. This component accommodates PC boards with specific thickness tolerances and offers a contact resistance of 30 mΩ.

Edgeboard Connectors Feature Summary

• Right-angle surface mount configuration with integrated locking mechanism

• Gold over nickel contact termination with bellowed styling
• Polybutylene terephthalate insulator material

Edgeboard Connectors Applications

• High-density electronic interconnects
• Industrial control system backplanes
• Telecommunications equipment interfaces
• Computing hardware peripheral connections

Edgeboard Connectors Procurement Notes

Verify that the target PCB design strictly adheres to the specified 0.125-inch contact center spacing to ensure proper alignment during assembly. Confirm that the board thickness falls within the acceptable tolerance range for mating compatibility. Ensure that the manufacturing environment supports right-angle surface mount soldering processes compatible with the specified terminal style. Validate that the application does not exceed the thermal ratings associated with the PBT insulator material.

Edgeboard Connectors Selection Notes

Select this model when a right-angle interface is required for space-constrained layouts. The dual-row format provides higher pin counts compared to single-row alternatives within similar footprint constraints. The locking feature is essential for applications requiring mechanical stability against vibration or accidental disconnection. Verify that the surface mount mounting option aligns with the automated assembly capabilities of the production line.

Edgeboard Connectors Part Context

This component belongs to the ESA series of card edge connectors produced by Sullins Connector Solutions. The series encompasses various configurations differing in row count, pitch, and mounting orientation. The ESA22DRSI-S288 specifically denotes a 44-position variant with right-angle surface mount terminals. It shares common design characteristics with other models in the family, such as standardized insulator materials and contact plating options.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers with identical electrical parameters and physical dimensions. Verify that substitute components maintain the same 0.125-inch pitch and dual-row layout. Ensure that any alternative connector supports the same right-angle surface mount installation method and locking mechanism requirements.
