EB41-S2R656XF Card Edge Connector - Equivalent & Substitute Parts

Part Overview

The EB41-S2R656XF is a 130-position female card edge connector manufactured by Vishay Dale, designed for dual-edge applications with 0.100" (2.54mm) pitch spacing. This connector features gold-plated phosphor bronze contacts, through-hole right-angle mounting, and operates across -65°C to 125°C. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB41-S2R656XF is determined by strict alignment of the following critical parameters:

• Electrical Compatibility: 130-position count, female gender, 0.100" (2.54mm) pitch, dual-edge configuration, and dual read-out capability
• Mechanical Compatibility: Through-hole right-angle mounting, card thickness acceptance range of 0.054" ~ 0.071" (1.37mm ~ 1.80mm), flush mount flange with top opening
• Contact Specifications: Phosphor bronze material with gold plating, cantilever contact type
• Environmental Specifications: Operating temperature range -65°C ~ 125°C

The EB43-S2R656XF qualifies as a direct substitute based on identical alignment across all critical electrical and mechanical parameters. Variations in insulation material and color do not affect functional compatibility within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

The EB43-S2R656XF is a functionally equivalent substitute for the EB41-S2R656XF. Both parts maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, mounting configuration, contact materials, and operating temperature range.

The primary distinction is product status: the EB41-S2R656XF is obsolete, while the EB43-S2R656XF is active. For new designs or ongoing system support requiring 130-position dual-edge card connectors with 0.100" pitch and gold-plated phosphor bronze contacts, the EB43-S2R656XF provides continued availability and supply chain stability.

Both parts carry identical RoHS non-compliance status and MSL rating. The variation in insulation material (DAP versus polyester thermoplastic) and connector color (green versus black) does not impact functional compatibility within the specified operating envelope.

Frequently Asked Questions (FAQ)

Q: Can the EB43-S2R656XF directly replace the EB41-S2R656XF in existing applications?

A: Yes. The EB43-S2R656XF maintains identical electrical and mechanical specifications. Both connectors accept the same card thickness range (0.054" ~ 0.071"), feature identical 130-position dual-edge configuration with 0.100" pitch, and operate across -65°C to 125°C. The connector color and insulation material differences do not affect functional compatibility.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by: 130-position count, female gender, 0.100" (2.54mm) pitch, dual-edge dual read-out configuration, through-hole right-angle mounting, card thickness acceptance of 0.054" ~ 0.071", phosphor bronze contacts with gold plating, cantilever contact type, and -65°C to 125°C operating temperature range.

Q: Does the insulation material change affect performance?

A: The EB41-S2R656XF uses diallyl phthalate (DAP) glass-filled insulation, while the EB43-S2R656XF uses polyester thermoplastic glass-filled insulation. Both materials are glass-filled and maintain the same electrical and mechanical performance within the specified operating parameters.

Q: Why is the EB41-S2R656XF listed as obsolete?

A: The EB41-S2R656XF is classified as obsolete by the manufacturer. The EB43-S2R656XF, with active product status, provides equivalent functionality with ongoing availability and supply chain support.

Q: Are there any compliance differences between these parts?

A: Both parts carry identical RoHS non-compliance status, MSL rating of 1 (Unlimited), ECCN classification (EAR99), and HTSUS code (8536.69.4040). No compliance differences exist between the two connectors.
