ESM43DTAN

Edgeboard Connectors Overview

The ESM43DTAN is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 86 positions arranged in two rows of 43 contacts, with a pitch of 0.156 inches (3.96 mm). The connector utilizes phosphor bronze contacts with a gold plating thickness of 10.0 µin (0.25 µm) and ring bellows contact types. Designed for through-hole mounting, it accommodates a card thickness of 0.062 inches (1.57 mm). The insulator is made of polybutylene terephthalate (PBT), and the unit is colored blue. It operates within a temperature range of -65°C to 125°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official Sullins documentation to confirm exact physical dimensions and material specifications. Ensure compatibility with the target PCB layout regarding hole patterns and spacing. Confirm that the gold plating thickness meets the application's wear requirements. Check RoHS compliance status if restricted substances are a concern for the end product.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge female connector with a 0.156-inch pitch is required. Consider the PBT insulation material for its thermal stability. Evaluate the through-hole mounting style against surface-mount alternatives. Verify that the 0.062-inch card thickness matches the design constraints. Assess the operating temperature range for environmental suitability.

Edgeboard Connectors Part Context

This component belongs to the ESM43 series of card edge connectors from Sullins Connector Solutions. The series offers various configurations differing in pitch, contact count, and mounting styles. The ESM43DTAN specifically denotes the dual-edge, 0.156-inch pitch variant with blue PBT insulation. It is part of a broader family designed for high-reliability applications in demanding environments.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include GSM43DTAN and ESM43DTKN, which share similar electrical characteristics but may differ in insulation material or mounting orientation. Verify mechanical fit before substitution.
