EB41-S0C2240W Equivalent & Substitute Parts

Part Overview

The EB41-S0C2240W is a 44-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 solder termination, and operates across a temperature range of -65°C to 125°C. The part is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB41-S0C2240W is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Number of positions (44), gender (female), pitch (0.100"), contact material (phosphor bronze), and contact finish (gold) must remain identical
• Mechanical Compatibility: Card type (dual edge), number of rows (2), card thickness tolerance (0.054" ~ 0.071"), and mounting type (through hole) must match exactly
• Environmental Specifications: Operating temperature range (-65°C ~ 125°C) and moisture sensitivity level (MSL 1) must be maintained
• Termination Method: Solder termination is required

The EB43-S0C2240W qualifies as a direct substitute based on full alignment with these parameters. Variations in insulation material and connector color do not affect functional compatibility within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The EB43-S0C2240W is the direct functional equivalent for the obsolete EB41-S0C2240W. Both connectors maintain identical electrical and mechanical specifications across all critical parameters: 44-position female configuration, 0.100" pitch, dual-edge card type, phosphor bronze gold-plated contacts, and -65°C to 125°C operating temperature range.

The primary distinction between these parts is product status: the EB41-S0C2240W is obsolete, while the EB43-S0C2240W is active and currently in production. Secondary differences in insulation material (DAP versus polyester thermoplastic) and connector color (green versus black) do not affect functional compatibility or electrical performance within the specified operating parameters.

Both parts carry identical RoHS non-compliance status and MSL 1 rating, indicating equivalent environmental handling and regulatory classification.

Frequently Asked Questions (FAQ)

Q: Can the EB43-S0C2240W directly replace the EB41-S0C2240W in existing designs?

A: Yes. The EB43-S0C2240W is electrically and mechanically equivalent to the EB41-S0C2240W. All critical parameters—position count, pitch, card type, contact material, contact finish, operating temperature, and termination method—are identical. The parts are interchangeable for functional purposes.

Q: What is the difference between the insulation materials used in these connectors?

A: The EB41-S0C2240W uses Diallyl Phthalate (DAP) glass-filled insulation, while the EB43-S0C2240W uses polyester thermoplastic glass-filled insulation. Both materials provide equivalent electrical and mechanical performance within the specified operating range. Material selection does not affect connector compatibility or electrical characteristics.

Q: Does the color difference between green (EB41) and black (EB43) affect compatibility?

A: No. Connector color is a cosmetic attribute and does not impact electrical performance, mechanical fit, or functional compatibility. Both colors are available within the same EB4 series and maintain identical specifications.

Q: Why is the EB41-S0C2240W classified as obsolete?

A: Obsolescence typically reflects manufacturing discontinuation by the supplier. The EB43-S0C2240W, as an active production part within the same series, provides continued availability for equivalent applications.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts share identical RoHS non-compliance status and MSL 1 (unlimited moisture sensitivity) rating. No regulatory or compliance differences exist between the two connectors.

Q: What card thickness tolerance must be maintained for proper connector operation?

A: Both connectors accommodate card thickness between 0.054" and 0.071" (1.37mm to 1.80mm). Cards must fall within this tolerance range to ensure proper contact engagement and electrical performance.
