EB73S-SA0660X Equivalent & Substitute Parts

Part Overview

The EB73S-SA0660X is a 12-position female card edge connector manufactured by Vishay Dale, designed for dual edge applications with 0.156" (3.96mm) pitch spacing. This connector features gold-plated phosphor bronze contacts, panel mount configuration, and solder eyelet termination. The product is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Substitute Part Grouping Explanation

The substitute part 356-006-500-102 (Mercury United Electronics, Inc.) qualifies as a functional equivalent based on the following critical parameters:

Connector Configuration: Both parts are 12-position female dual edge connectors with identical pitch spacing (0.156" / 3.96mm)
Mechanical Compatibility: Card thickness acceptance range is compatible (main part: 0.054" ~ 0.071"; substitute: 0.054" ~ 0.070")
Electrical Interface: Both feature gold-plated contacts with solder eyelet termination for panel mount applications
Form Factor: Identical flange design (flush mount, top opening, unthreaded, 0.128" dia)
Environmental Classification: Both rated MSL 1 (unlimited moisture sensitivity)

Substitution is valid within the overlapping card thickness range of 0.054" ~ 0.070" (1.37mm ~ 1.78mm).

Engineering Selection Recommendations

The 356-006-500-102 is the manufacturer-recommended substitute for the obsolete EB73S-SA0660X. Selection of this substitute is supported by:

Product Status: The substitute is active production, ensuring long-term availability and supply chain continuity
Regulatory Compliance: The substitute meets ROHS3 compliance requirements, whereas the original part is RoHS non-compliant
Mechanical Compatibility: Identical pitch, position count, and form factor ensure direct mechanical fit within the overlapping card thickness specification
Electrical Interface: Gold-plated contacts and solder eyelet termination provide equivalent electrical performance for panel mount applications

Temperature Consideration: The substitute operates within -40°C ~ 105°C, which is narrower than the original -55°C ~ 125°C range. Applications requiring operation below -40°C or above 105°C must evaluate alternative solutions.

Contact Design Difference: The substitute uses cantilever contacts versus the original full bellows design. Both contact types are suitable for card edge applications; however, contact force and engagement characteristics differ slightly.

Frequently Asked Questions (FAQ)

Q: Can the 356-006-500-102 be used as a direct replacement in all applications?

A: The substitute is mechanically and electrically compatible for card thicknesses within 0.054" ~ 0.070" (1.37mm ~ 1.78mm). Applications requiring operation outside the -40°C ~ 105°C temperature range must evaluate alternative solutions.

Q: What is the difference between full bellows and cantilever contact types?

A: Full bellows contacts provide distributed contact force across a wider engagement area, while cantilever contacts concentrate force at the contact point. Both designs are suitable for card edge connectors; selection depends on specific application requirements for contact force and wear characteristics.

Q: Does the substitute meet current regulatory requirements?

A: Yes, the 356-006-500-102 is ROHS3 compliant, meeting current regulatory standards. The original EB73S-SA0660X is RoHS non-compliant.

Q: Are there packaging differences between the original and substitute?

A: The original part packaging is not specified. The substitute is supplied in bulk packaging.

Q: What is the card thickness compatibility window?

A: Both connectors accept cards within 0.054" ~ 0.070" (1.37mm ~ 1.78mm). The original part specification extends to 0.071" (1.80mm), which exceeds the substitute's maximum tolerance.

Q: Is the substitute available in current inventory?

A: The 356-006-500-102 has 819 pieces in new original stock.
