EB41-S0K206XF Card Edge Connector - Equivalent & Substitute Parts

Part Overview

The EB41-S0K206XF is a 40-position female card edge connector manufactured by Vishay Dale, designed for dual-edge applications with 0.100" (2.54mm) pitch spacing. This connector features wire wrap termination, phosphor bronze contacts with gold finish, and operates across -65°C to 125°C. The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

Substitution eligibility for the EB41-S0K206XF is determined by strict alignment of the following critical parameters:

Electrical Interface: 40 positions, 0.100" (2.54mm) pitch, dual-edge configuration, female gender
Mechanical Compatibility: Through-hole mounting, wire wrap termination, card thickness acceptance range 0.054" ~ 0.071" (1.37mm ~ 1.80mm)
Contact Specifications: Phosphor bronze material with gold finish
Environmental Rating: Operating temperature range -65°C ~ 125°C
Physical Form Factor: Flush mount flange with top opening, unthreaded 0.125" (3.18mm) diameter

The EB43-S0K206XF meets all critical substitution criteria. Variations in insulation material color do not affect functional compatibility when all electrical and mechanical parameters remain constant.

Engineering Selection Recommendations

The EB43-S0K206XF is a direct functional substitute for the obsolete EB41-S0K206XF. Both connectors share identical electrical and mechanical specifications across all critical parameters: 40-position dual-edge configuration, 0.100" pitch, wire wrap termination, phosphor bronze gold-plated contacts, and -65°C to 125°C operating range.

The primary distinction is product status: EB43-S0K206XF is currently active with 825 units in stock, whereas EB41-S0K206XF is obsolete. The insulation material differs (polyester thermoplastic versus diallyl phthalate), and the connector color is black instead of green. These variations do not affect electrical performance or mechanical compatibility in standard applications.

Both parts carry identical RoHS non-compliant status and MSL rating of 1 (Unlimited). Selection between these parts should be based on availability and procurement timeline, with EB43-S0K206XF recommended for new procurement due to active product status.

Frequently Asked Questions (FAQ)

Q: Can EB43-S0K206XF directly replace EB41-S0K206XF in existing designs?

A: Yes. All critical electrical and mechanical parameters are identical. The connector accepts the same card thickness range (0.054" ~ 0.071"), maintains the same 40-position dual-edge configuration with 0.100" pitch, and uses identical contact materials and finishes.

Q: Does the insulation material change affect performance?

A: No. Both insulation materials (diallyl phthalate and polyester thermoplastic) are glass-filled and rated for the same operating temperature range (-65°C ~ 125°C). The material change does not impact electrical or mechanical function.

Q: Why is the connector color different?

A: Color is a cosmetic specification only and does not affect electrical or mechanical compatibility. EB43-S0K206XF uses black insulation while EB41-S0K206XF uses green. Both connectors are functionally equivalent.

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 advantage exists between the two parts.

Q: What is the primary reason to select EB43-S0K206XF?

A: EB43-S0K206XF is currently active with confirmed inventory availability (825 units in stock), whereas EB41-S0K206XF is obsolete. For ongoing procurement and system support, EB43-S0K206XF is the appropriate selection.
