EB41-S0D3640X Card Edge Connector Equivalent & Substitute Parts

Part Overview

The EB41-S0D3640X is a 72-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 -65°C to 125°C. The part is currently obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the EB41-S0D3640X is determined by strict alignment of the following critical parameters:

Connector Type & Configuration: Dual-edge female card edge connector
Position Count: 72 positions (36 per row)
Pitch Specification: 0.100" (2.54mm)
Card Thickness Tolerance: 0.054" ~ 0.071" (1.37mm ~ 1.80mm)
Contact Characteristics: Phosphor bronze material with gold plating, cantilever contact type
Electrical Interface: Solder termination, through-hole mounting
Environmental Range: -65°C to 125°C operating temperature

The EB43-S0D3640X qualifies as a direct substitute because it maintains identical specifications across all critical parameters. Variations in insulation material (Diallyl Phthalate vs. Polyester Thermoplastic) and connector color (Green vs. Black) do not affect functional compatibility, as these are secondary characteristics that do not impact electrical performance or mechanical fit within the specified card thickness range.

Engineering Selection Recommendations

The EB43-S0D3640X is the appropriate substitute for the obsolete EB41-S0D3640X. The primary advantage of this substitution is product status: EB43-S0D3640X maintains active manufacturing status with confirmed inventory availability (714 pcs), ensuring long-term supply chain continuity compared to the obsolete EB41-S0D3640X.

Both parts maintain identical electrical and mechanical specifications, including 72-position dual-edge configuration, 0.100" pitch, phosphor bronze gold-plated contacts, and -65°C to 125°C operating range. The insulation material difference (Diallyl Phthalate vs. Polyester Thermoplastic) does not affect functional compatibility, as both are glass-filled polymers suitable for the specified operating environment. Both parts carry identical RoHS non-compliant status and MSL rating.

For applications requiring new component procurement or system redesign, the EB43-S0D3640X provides equivalent performance with the advantage of active product status and current manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the EB43-S0D3640X directly replace the EB41-S0D3640X in existing designs?

A: Yes. Both connectors share identical electrical and mechanical specifications: 72 positions, 0.100" pitch, dual-edge female configuration, phosphor bronze gold-plated contacts, and -65°C to 125°C operating range. The card thickness tolerance (0.054" ~ 0.071") is identical, ensuring mechanical fit compatibility.

Q: What is the difference between the green and black color variants?

A: Color is a cosmetic characteristic that does not affect electrical performance or mechanical function. Selection between green (EB41-S0D3640X) and black (EB43-S0D3640X) variants depends on application requirements or design preferences only.

Q: Why is insulation material different between these parts?

A: The EB41-S0D3640X uses Diallyl Phthalate (DAP) while the EB43-S0D3640X uses Polyester Thermoplastic. Both are glass-filled polymers with equivalent performance characteristics for this connector category. This material variation does not impact compatibility or electrical specifications.

Q: Is the EB43-S0D3640X suitable for new designs?

A: Yes. The EB43-S0D3640X maintains active product status with current manufacturing support, making it the recommended choice for new designs requiring 72-position dual-edge card edge connectors with 0.100" pitch specifications.

Q: What is the significance of product status (Obsolete vs. Active)?

A: Product status indicates manufacturing availability. The EB41-S0D3640X is obsolete and no longer manufactured. The EB43-S0D3640X is active with confirmed inventory, ensuring availability for procurement and long-term supply chain support.

Q: Are there any compliance differences between these parts?

A: Both parts carry identical RoHS non-compliant status and MSL rating of 1 (Unlimited). No compliance advantages exist between the two variants.
