Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EB73D-SA2240X is determined by the following critical parameters:

• Position Count & Pitch: 44 positions at 0.156" (3.96mm) spacing is the primary functional requirement
• Connector Type: Dual-edge, female gender configuration
• Contact System: Phosphor bronze with gold plating ensures electrical performance and corrosion resistance
• Mounting & Termination: Panel mount with solder eyelet termination for PCB integration
• Environmental Rating: Operating temperature range compatibility

The GSM22DSEH from Sullins Connector Solutions meets all critical substitution criteria. Both connectors share identical position counts, pitch spacing, dual-edge configuration, contact materials, and termination methods. The substitute maintains functional and electrical equivalence while offering improved product status and compliance certifications.

Engineering Selection Recommendations

The GSM22DSEH is the direct functional equivalent for the obsolete EB73D-SA2240X. Selection of the Sullins substitute is supported by the following factors:

• Product Availability: The GSM22DSEH maintains active product status with 817 units in stock, ensuring supply chain continuity
• Regulatory Compliance: ROHS3 compliance of the substitute addresses modern environmental and regulatory requirements, whereas the original part is non-compliant
• Thermal Performance: The substitute's extended lower operating temperature limit (-65°C versus -55°C) provides enhanced environmental tolerance
• Mechanical Compatibility: Identical position count, pitch, and termination method ensure direct PCB integration without layout modifications
• Contact System: Matching phosphor bronze with gold plating maintains electrical performance specifications

Frequently Asked Questions (FAQ)

Q: Can the GSM22DSEH directly replace the EB73D-SA2240X in existing designs?

A: Yes. Both connectors share identical position counts (44), pitch spacing (0.156"), dual-edge configuration, contact materials, and solder eyelet termination. No PCB layout or design modifications are required.

Q: What is the significance of the card thickness difference between the two parts?

A: The EB73D-SA2240X accommodates card thickness of 0.054" ~ 0.071" (1.37mm ~ 1.80mm), while the GSM22DSEH is specified for 0.062" (1.57mm). The substitute's specification falls within the original part's tolerance range, ensuring mechanical compatibility with standard card edge designs.

Q: Does the RoHS3 compliance of the GSM22DSEH affect electrical performance?

A: No. RoHS3 compliance reflects manufacturing process standards and material restrictions. The electrical and mechanical performance characteristics remain equivalent to the original part.

Q: Are there packaging differences between these connectors?

A: The EB73D-SA2240X packaging is unspecified, while the GSM22DSEH is supplied in Tray packaging. This difference affects logistics and handling but does not impact connector functionality or performance.

Q: What is the contact finish thickness specification for the substitute?

A: The GSM22DSEH specifies a contact finish thickness of 10.0µin (0.25µm) gold plating. The original part does not provide this specification detail.
