Key Parameters

Substitute Part Grouping Explanation

Substitution of the EB71S-SA1540V is determined by the following critical parameters that must remain consistent:

• Connector Type & Configuration: 30-position female card edge connector with dual edge design
• Pitch Specification: 0.156" (3.96mm) center-to-center spacing
• Contact Finish: Gold plating for electrical performance and corrosion resistance
• Mounting & Termination: Panel mount with solder eyelet termination
• Electrical Interface: Single read-out configuration

The EBT156-15A2X qualifies as a direct substitute based on matching these core parameters. Both connectors maintain identical position count, pitch, gender, dual-edge configuration, contact finish, mounting type, and termination method. Differences in card thickness tolerance, insulation material, and color do not affect functional compatibility within the specified operating envelope.

Engineering Selection Recommendations

The EBT156-15A2X is the manufacturer-recommended substitute for the obsolete EB71S-SA1540V. Selection of this substitute is supported by the following factors:

Product Status: The EB71S-SA1540V is obsolete, while the EBT156-15A2X maintains active production status, ensuring long-term availability and supply chain continuity.

Electrical & Mechanical Compatibility: Both connectors share identical position count, pitch, gender configuration, and contact finish specifications. The card thickness of the EBT156-15A2X (0.062") falls within the acceptable range of the EB71S-SA1540V (0.054" ~ 0.071"), ensuring proper mechanical engagement and electrical contact.

Compliance & Certifications: Both parts carry identical HTSUS and ECCN classifications (8536.69.4040 and EAR99 respectively), with matching Moisture Sensitivity Level (MSL 1 - Unlimited). Both are RoHS non-compliant, maintaining consistency with legacy system requirements.

Insulation Material Difference: The EB71S-SA1540V uses Diallyl Phthalate (DAP) insulation, while the EBT156-15A2X uses Phenol Formaldehyde (Phenolic) with glass filling. This material change does not affect functional compatibility, as both materials meet the operating temperature range and electrical isolation requirements for this connector class.

Frequently Asked Questions (FAQ)

Q: Can the EBT156-15A2X directly replace the EB71S-SA1540V in existing assemblies?

A: Yes. Both connectors maintain identical position count (30), pitch (0.156"), gender (female), dual-edge configuration, contact finish (gold), mounting type (panel mount), and termination method (solder eyelet). The card thickness of the substitute (0.062") is within the tolerance range of the original (0.054"
