EB61-S0K186FS Equivalent & Substitute Parts

Part Overview

The EB61-S0K186FS is a 36-position female card edge connector manufactured by Vishay Dale, featuring dual-row configuration with 0.125" (3.18mm) pitch spacing. This connector is designed for through-hole wire wrap termination applications with gold-plated phosphor bronze contacts. The part is currently classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EB61-S0K186FS is determined by strict equivalence across the following critical parameters:

• Connector Type & Configuration: Card edge dual-row female connector
• Position Count & Pitch: 36 positions total, 18 positions per row, 0.125" (3.18mm) pitch
• Card Acceptance: Dual edge, 0.054" ~ 0.071" (1.37mm ~ 1.80mm) thickness
• Electrical Interface: Gold-plated phosphor bronze cantilever contacts
• Termination Method: Wire wrap through-hole mounting
• Environmental Rating: -65°C ~ 125°C operating temperature range

The EB63-S0K186FS qualifies as a direct substitute based on identical compliance across all mechanical and electrical parameters. Variation in insulation material (polyester thermoplastic, glass-filled versus diallyl phthalate) and connector color (black versus green) does not affect functional compatibility within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The EB63-S0K186FS is the direct functional equivalent for the obsolete EB61-S0K186FS. Both connectors maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, card acceptance range, contact material, and operating temperature envelope.

The EB63-S0K186FS offers the advantage of active product status, ensuring continued availability and supply chain support. Both parts carry equivalent RoHS non-compliance classification and moisture sensitivity ratings. The insulation material difference (polyester thermoplastic, glass-filled versus diallyl phthalate) and color variation (black versus green) represent cosmetic and material property distinctions that do not impact functional interchangeability within the specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the EB63-S0K186FS directly replace the EB61-S0K186FS in existing designs?

A: Yes. The EB63-S0K186FS is mechanically and electrically equivalent. Both connectors accept identical card thickness ranges, maintain the same 36-position dual-row configuration at 0.125" pitch, and feature gold-plated phosphor bronze cantilever contacts rated for -65°C ~ 125°C operation.

Q: What is the difference between the EB61-S0K186FS and EB63-S0K186FS?

A: The primary differences are product status (obsolete versus active), insulation material composition (diallyl phthalate versus polyester thermoplastic, glass-filled), and connector color (green versus black). These variations do not affect electrical performance or mechanical compatibility.

Q: Are there any compatibility concerns with the insulation material change?

A: No. Both insulation materials are rated for the same operating temperature range (-65°C ~ 125°C) and moisture sensitivity level (MSL 1, Unlimited). The material substitution does not impact connector function or reliability within specified conditions.

Q: Does the color difference affect connector selection?

A: Color is a cosmetic attribute and does not influence electrical or mechanical performance. Selection should be based on design requirements and available inventory.

Q: What is the card thickness acceptance range for these connectors?

A: Both the EB61-S0K186FS and EB63-S0K186FS accept printed circuit cards with thickness between 0.054" and 0.071" (1.37mm to 1.80mm).

Q: Are both parts RoHS compliant?

A: No. Both the EB61-S0K186FS and EB63-S0K186FS are classified as RoHS non-compliant. If RoHS compliance is required, alternative connector families must be evaluated.
