EB71S-SA0660X Equivalent & Substitute Parts

Part Overview

The EB71S-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 and operates across -55°C to 125°C. The product is classified as obsolete, necessitating identification of active equivalent components that maintain functional compatibility for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EB71S-SA0660X is determined by the following critical parameters that must remain consistent:

• Connector Type & Configuration: 12-position female card edge connector with dual edge configuration
• Pitch Specification: 0.156" (3.96mm) center-to-center spacing
• Number of Rows: 2 rows of contacts
• Mounting Interface: Panel mount with solder eyelet termination
• Electrical Compatibility: Single read-out configuration

The EBT156-6A1X qualifies as a functional substitute based on matching these core parameters. Variations in contact material finish (gold vs. tin), insulation material composition, and flange diameter do not prevent electrical or mechanical compatibility within the specified card thickness range, provided the application does not impose specific requirements for contact finish or operating temperature beyond the substitute's capabilities.

Parameter Comparison

Engineering Selection Recommendations

The EBT156-6A1X is the manufacturer-recommended substitute for the obsolete EB71S-SA0660X. Both components share identical pitch, position count, row configuration, and mounting methodology. The substitute maintains active product status, ensuring ongoing availability and supply chain continuity.

Key considerations for selection:

• Contact Finish Difference: The substitute uses tin plating instead of gold. This change is acceptable for general-purpose applications but may affect performance in high-reliability or corrosive environments where gold plating provides superior oxidation resistance.
• Insulation Material: The substitute employs glass-filled phenolic insulation versus the original's DAP material. Both materials provide adequate electrical insulation and mechanical support within the specified operating parameters.
• Card Thickness Compatibility: The substitute is specified for 0.062" (1.57mm) card thickness, which falls within the original's 0.054" to 0.071" tolerance range, ensuring mechanical fit.
• Compliance Status: Both components carry identical RoHS non-compliance and MSL ratings, maintaining consistency with existing design documentation.

Frequently Asked Questions (FAQ)

Q: Can the EBT156-6A1X directly replace the EB71S-SA0660X in existing designs?

A: Yes. Both connectors share identical pitch (0.156"), position count (12), row configuration (2), and mounting type (panel mount solder eyelet). The substitute's card thickness specification (0.062") is compatible with the original's tolerance range (0.054" to 0.071").

Q: What is the impact of switching from gold to tin contact finish?

A: Gold plating provides superior corrosion resistance and lower contact resistance in harsh environments. Tin plating is suitable for standard applications with normal environmental exposure. Selection depends on application-specific requirements for reliability and environmental conditions.

Q: Are there any packaging differences between these connectors?

A: The original EB71S-SA0660X is listed with unspecified packaging, while the EBT156-6A1X is supplied in bulk packaging. This affects procurement and handling but does not impact electrical or mechanical performance.

Q: Do both connectors meet the same compliance standards?

A: Both components are RoHS non-compliant and carry identical MSL ratings (1 - Unlimited). They share the same ECCN (EAR99) and HTSUS classification, maintaining regulatory consistency.

Q: What is the significance of the flange diameter difference?

A: The flange diameter increases from 0.128" (3.25mm) to 0.140" (4.66mm). This minor dimensional change does not affect electrical performance and remains within typical mechanical tolerances for panel-mount applications.
