Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB71S-SA2260X is determined by the following critical parameters:

Primary Compatibility Criteria:

• Number of Positions: 44 (fixed requirement)
• Pitch: 0.156" (3.96mm) (fixed requirement)
• Gender: Female (fixed requirement)
• Card Type: Dual Edge (fixed requirement)
• Number of Rows: 2 (fixed requirement)
• Mounting Type: Panel Mount (fixed requirement)
• Termination: Solder Eyelet(s) (fixed requirement)

Secondary Compatibility Parameters:

• Contact Finish: Gold (maintained across substitutes)
• Card Thickness Tolerance: Must accommodate 0.054" ~ 0.071" (1.37mm ~ 1.80mm) range or compatible range

The EBT156-22A2X qualifies as a manufacturer-recommended substitute. While minor variations exist in contact material composition, insulation material, and flange diameter specifications, the part maintains functional equivalence across all primary compatibility criteria. The EBT156-22A2X operates within the same pitch and position configuration, ensuring direct mechanical and electrical compatibility in applications designed for the EB71S-SA2260X.

Parameter Comparison

Engineering Selection Recommendations

The EBT156-22A2X is the manufacturer-recommended substitute for the obsolete EB71S-SA2260X. Selection of this substitute is supported by the following engineering factors:

Product Status Consideration: The EB71S-SA2260X is classified as obsolete, creating supply chain risk for new production and field replacements. The EBT156-22A2X maintains active product status with Vishay Dale, ensuring ongoing availability and manufacturing support.

Functional Equivalence: Both connectors maintain identical specifications across all primary compatibility parameters: 44-position configuration, 0.156" pitch, female gender, dual-edge card type, panel mount configuration, and solder eyelet termination. The card thickness specification of the EBT156-22A2X (0.062") falls within the acceptable tolerance range of the original part (0.054" ~ 0.071").

Compliance Alignment: Both parts share identical RoHS and ECCN classifications (EAR99), maintaining regulatory consistency in applications where these certifications are required.

Contact Finish Specification: Gold plating is maintained on both parts, preserving electrical performance and corrosion resistance characteristics in the connector interface.

Frequently Asked Questions (FAQ)

Q: Can the EBT156-22A2X directly replace the EB71S-SA2260X in existing applications?

A: Yes. The EBT156-22A2X is the manufacturer-recommended substitute and maintains identical specifications across all primary compatibility parameters: 44 positions, 0.156" pitch, female gender, dual-edge configuration, and panel mount termination. The card thickness of 0.062" is within the acceptable range of the original part.

Q: What are the key differences between these two connectors?

A: The primary differences are: (1) Product Status—the EB71S-SA2260X is obsolete while the EBT156-22A2X is active; (2) Insulation Material—DAP versus Phenol Formaldehyde with glass fill; (3) Flange Diameter—0.128" versus 0.140"; (4) Contact Material—Phosphor Bronze versus Copper Alloy. These differences do not affect functional compatibility in standard applications.

Q: Are there any mechanical considerations when substituting the EBT156-22A2X?

A: The flange diameter difference (0.128" to 0.140") is minor and should not impact panel mount installation in standard applications. The card thickness specification of the EBT156-22A2X (0.062") is centered within the original part's tolerance range (0.054" ~ 0.071"), ensuring proper contact engagement.

Q: What is the packaging difference between these parts?

A: The EB71S-SA2260X is supplied in unspecified packaging, while the EBT156-22A2X is supplied in bulk packaging. This difference affects procurement and handling but does not impact electrical or mechanical performance.

Q: Are both parts RoHS compliant?

A: No. Both the EB71S-SA2260X and EBT156-22A2X are classified as RoHS non-compliant. If RoHS compliance is required for your application, alternative connector solutions must be evaluated.

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

A: The operating temperature specification is not provided for the EBT156-22A2X in the available data. The original EB71S-SA2260X operates from -55°C to 125°C. Confirm operating temperature requirements with Vishay Dale technical documentation if this parameter is critical for your application.
