EB71S-SB1260W Card Edge Connector Equivalent & Substitute Parts

Part Overview

The EB71S-SB1260W is a 24-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 is rated for operating temperatures from -55°C to 125°C. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB71S-SB1260W is determined by the following critical parameters:

• Position Count & Pitch: 24 positions at 0.156" (3.96mm) spacing (mandatory match)
• Connector Type: Female, dual edge card edge connector (mandatory match)
• Mounting & Termination: Through hole solder termination (mandatory match)
• Contact Finish: Gold plating (mandatory match)
• Card Thickness Compatibility: Acceptable range for dual edge insertion
• Operating Temperature Range: Minimum -55°C to 125°C capability
• Insulation Material & Moisture Sensitivity: Suitable for intended application environment

The EBT156-12C2W meets all mandatory substitution criteria. While it differs in insulation material (Phenol Formaldehyde vs. Diallyl Phthalate) and contact material composition (Copper Alloy vs. Phosphor Bronze), these variations remain within acceptable electrical and mechanical parameters for dual edge card edge connector applications at this pitch and position count.

Parameter Comparison

Engineering Selection Recommendations

The EBT156-12C2W is the designated substitute for the obsolete EB71S-SB1260W. Selection is based on the following factors:

• Product Status: The EBT156-12C2W maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete EB71S-SB1260W.
• Electrical & Mechanical Compatibility: Both connectors share identical position count, pitch, gender, row configuration, and mounting method. The card thickness specification of 0.062" (1.57mm) for the EBT156-12C2W falls within the acceptable range of the original part.
• Contact & Termination Specifications: Gold contact finish and solder termination are preserved, maintaining signal integrity and assembly compatibility.
• Compliance Alignment: Both parts carry identical RoHS non-compliance and MSL ratings, ensuring consistent handling and environmental requirements.
• Insulation Material Difference: The EBT156-12C2W uses glass-filled phenolic insulation instead of DAP. This material change does not affect connector function within the specified operating parameters and is standard in modern connector design.

Frequently Asked Questions (FAQ)

Q: Can the EBT156-12C2W directly replace the EB71S-SB1260W in existing designs?

A: Yes. Both connectors are 24-position female dual edge card edge connectors with 0.156" pitch, identical mounting and termination methods, and gold contact finish. The card thickness specification of 0.062" (1.57mm) for the substitute falls within the acceptable insertion range.

Q: What is the primary reason for substitution?

A: The EB71S-SB1260W is obsolete. The EBT156-12C2W is an active production part from the same manufacturer, providing equivalent functionality with assured supply availability.

Q: Are there differences in insulation material between these connectors?

A: Yes. The EB71S-SB1260W uses Diallyl Phthalate (DAP) insulation, while the EBT156-12C2W uses glass-filled Phenol Formaldehyde (Phenolic) insulation. Both materials are suitable for the specified operating temperature range of -55°C to 125°C and maintain identical moisture sensitivity ratings.

Q: Do both connectors have the same contact material?

A: The contact materials differ slightly. The EB71S-SB1260W uses phosphor bronze, while the EBT156-12C2W uses copper alloy. Both are gold-plated and suitable for the same electrical applications at this connector pitch and position count.

Q: Are there packaging differences?

A: The EB71S-SB1260W is supplied in unspecified packaging, while the EBT156-12C2W is supplied in bulk packaging. This does not affect connector performance or compatibility.

Q: What is the operating temperature range for the substitute?

A: The EBT156-12C2W does not specify an operating temperature range in the provided data. The original EB71S-SB1260W is rated -55°C to 125°C. Verify temperature requirements with the manufacturer if operation outside standard industrial ranges is required.
