Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the EB73D-SA1240X is determined by the following critical parameters:

• Position Count & Pitch: 24 positions at 0.156" (3.96mm) spacing
• Connector Type: Female, dual edge card edge configuration
• Contact System: Phosphor bronze with gold plating, full bellows contact type
• Mounting & Termination: Panel mount with solder eyelet termination
• Mechanical Compatibility: Card thickness acceptance range and flange dimensions
• Environmental Rating: Operating temperature range and material composition

The GSM12DSEH from Sullins Connector Solutions meets these core substitution criteria. Both connectors share identical position counts, pitch spacing, gender, contact material, contact finish, mounting type, and termination method. The substitute maintains functional and mechanical compatibility within the specified parameters.

Engineering Selection Recommendations

The GSM12DSEH is the designated manufacturer-recommended substitute for the EB73D-SA1240X. Selection of this substitute is supported by the following factors:

Product Status: The original EB73D-SA1240X is obsolete, while the GSM12DSEH maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance & Certifications: The GSM12DSEH is ROHS3 compliant, whereas the original part is RoHS non-compliant. Both parts are REACH unaffected and carry the same ECCN and HTSUS classifications.

Electrical & Mechanical Compatibility: All critical electrical parameters—position count, pitch, contact material, contact finish, and contact type—are identical. Mechanical compatibility is maintained through matching mounting type, termination method, and flange configuration. The substitute's card thickness specification of 0.062" (1.57mm) falls within the original part's acceptance range of 0.054" ~ 0.071" (1.37mm ~ 1.80mm).

Environmental Performance: The GSM12DSEH provides an extended lower operating temperature limit of -65°C compared to the original -55°C, offering improved thermal performance across the full operating range.

Frequently Asked Questions (FAQ)

Q: Can the GSM12DSEH directly replace the EB73D-SA1240X in existing designs?

A: Yes. Both connectors share identical position counts, pitch spacing, contact configuration, and termination methods. The substitute maintains mechanical compatibility with card thicknesses within the specified range.

Q: What is the significance of the card thickness difference?

A: The EB73D-SA1240X accepts cards from 0.054" to 0.071" (1.37mm to 1.80mm). The GSM12DSEH is specified for 0.062" (1.57mm) cards, which falls within this range. Verify your specific card thickness against both specifications before implementation.

Q: Why is the GSM12DSEH recommended over other potential substitutes?

A: The GSM12DSEH is the manufacturer-recommended substitute, meeting all critical electrical and mechanical parameters while offering active product status and improved compliance certifications.

Q: Are there packaging differences between these connectors?

A: The EB73D-SA1240X packaging is not specified in available documentation. The GSM12DSEH is supplied in tray packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: What is the impact of the RoHS compliance difference?

A: The original EB73D-SA1240X is RoHS non-compliant, while the GSM12DSEH is ROHS3 compliant. For applications subject to RoHS regulations, the substitute provides regulatory compliance. For legacy systems without RoHS requirements, both parts are functionally equivalent.

Q: How do the operating temperature ranges compare?

A: The GSM12DSEH extends the lower temperature limit to -65°C versus the original -55°C, providing broader thermal performance. Both maintain the same upper limit of 125°C.
