Key Parameters

Substitute Part Grouping Explanation

Substitution for the EB41-S2R3560X is determined by strict electrical and mechanical compatibility across the following critical parameters:

• Connector Type & Configuration: Card edge, dual edge, female gender, 70 positions across 2 rows
• Pitch & Spacing: 0.100" (2.54mm) pitch requirement
• Physical Dimensions: Card thickness acceptance range of 0.054" ~ 0.071" (1.37mm ~ 1.80mm)
• Mounting & Termination: Through-hole, right-angle mounting with solder termination
• Contact Specifications: Phosphor bronze material with gold finish
• Electrical Performance: Operating temperature range of -65°C ~ 125°C

The EB43-S2R3560X meets all these criteria and qualifies as a direct substitute within the EB4 series.

Parameter Comparison

Engineering Selection Recommendations

The EB43-S2R3560X is the direct substitute for the EB41-S2R3560X. Both connectors share identical electrical and mechanical specifications across all critical parameters: 70-position dual-edge configuration, 0.100" pitch, phosphor bronze gold-plated contacts, and -65°C to 125°C operating temperature range.

The primary distinction between these parts is product status and regulatory compliance. The EB41-S2R3560X is obsolete, while the EB43-S2R3560X maintains active production status. Additionally, the EB43-S2R3560X is ROHS3 compliant, whereas the EB41-S2R3560X is RoHS non-compliant. The insulation material differs (polyester glass-filled versus diallyl phthalate glass-filled), and the connector color is black instead of green. These differences do not affect functional compatibility in applications requiring the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Are the EB41-S2R3560X and EB43-S2R3560X electrically interchangeable?

A: Yes. Both connectors feature identical contact materials (phosphor bronze with gold finish), pitch spacing (0.100"), number of positions (70), and operating temperature range (-65°C to 125°C). They are electrically interchangeable.

Q: What is the significance of the product status difference?

A: The EB41-S2R3560X is classified as obsolete, indicating discontinued production. The EB43-S2R3560X is active, meaning it remains in current production with ongoing availability. For new designs and long-term supply assurance, the active part is preferred.

Q: Does the insulation material change affect mechanical compatibility?

A: No. Both insulators are glass-filled materials meeting the same mechanical requirements. The change from diallyl phthalate to polyester does not impact card thickness acceptance (0.054" ~ 0.071") or mounting characteristics.

Q: Is RoHS compliance a functional requirement for substitution?

A: RoHS compliance is a regulatory and environmental requirement, not a functional electrical or mechanical parameter. The EB43-S2R3560X's ROHS3 compliance makes it suitable for applications with regulatory requirements. The EB41-S2R3560X remains functionally compatible in applications without such constraints.

Q: Does the color difference (green vs. black) affect performance?

A: No. Color is a cosmetic identifier only and does not affect electrical performance, mechanical fit, or thermal characteristics.

Q: Can the EB43-S2R3560X be used as a direct replacement in existing assemblies?

A: Yes. The EB43-S2R3560X maintains identical card thickness acceptance, pitch, position count, and mounting configuration. It is a direct mechanical and electrical replacement.
