EB71S-SB2260V Card Edge Connector Equivalent & Substitute Parts

Part Overview

The EB71S-SB2260V is a 44-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, through-hole solder termination, and operates across -55°C to 125°C. The part is classified as obsolete, making identification of compatible substitutes essential for ongoing system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB71S-SB2260V is determined by the following critical parameters:

Primary Compatibility Criteria:

• Number of positions: 44
• Pitch spacing: 0.156" (3.96mm)
• Gender: Female
• Card configuration: Dual Edge
• Number of rows: 2
• Contact finish: Gold plating

Secondary Compatibility Criteria:

• Card thickness acceptance range
• Mounting and termination method
• Operating temperature range
• Contact material composition

The substitute part EBT156-22A2X maintains all primary compatibility criteria, ensuring functional equivalence in dual-edge 44-position applications with matching pitch and contact specifications.

Parameter Comparison

Engineering Selection Recommendations

The EBT156-22A2X serves as the manufacturer-recommended substitute for the obsolete EB71S-SB2260V. Both connectors maintain identical electrical specifications for 44-position, dual-edge, 0.156" pitch applications with gold-plated contacts.

Status Consideration: The EB71S-SB2260V is classified as obsolete, while the EBT156-22A2X maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance Alignment: Both parts share identical RoHS and REACH classifications, maintaining consistent regulatory compliance profiles for applications requiring non-compliant component documentation.

Physical Differences: The substitute features panel mount configuration with solder eyelet termination, compared to the original through-hole solder termination. Card thickness specification for the substitute (0.062") falls within the acceptable range of the original (0.054" ~ 0.071"). Contact material differs (copper alloy versus phosphor bronze), though both maintain gold finish specifications.

Frequently Asked Questions (FAQ)

Q: Can the EBT156-22A2X directly replace the EB71S-SB2260V in existing designs?

A: The EBT156-22A2X maintains functional equivalence for 44-position, dual-edge, 0.156" pitch applications. Mounting configuration differs (panel mount versus through-hole), requiring PCB layout evaluation. Termination method differs (solder eyelet versus solder), necessitating assembly process compatibility assessment.

Q: What are the critical parameters for substitution compatibility?

A: Position count (44), pitch spacing (0.156"), gender (female), dual-edge configuration, row count (2), and gold contact finish are non-negotiable for functional equivalence. Card thickness, mounting method, and termination style may vary within specified tolerances.

Q: Why is the substitute part classified as active while the original is obsolete?

A: The EBT156-22A2X represents the current production equivalent within Vishay Dale's connector portfolio. Obsolescence of the EB71S-SB2260V reflects discontinuation of that specific design variant in favor of the EBT156 series.

Q: Are there compliance differences between the two parts?

A: Both parts share identical RoHS non-compliant and REACH unaffected classifications. Regulatory compliance profiles remain consistent for substitution purposes.

Q: What design considerations apply to the mounting type difference?

A: The original EB71S-SB2260V uses through-hole mounting, while the EBT156-22A2X uses panel mount configuration. PCB footprint and mounting hole placement require verification against design specifications before implementation.
