Key Parameters

Substitute Part Grouping Explanation

Substitution of the S-80947CNNB-G9HT2G is determined by strict equivalence across the following critical parameters:

• Voltage threshold: 4.7V
• Output type: Open Drain or Open Collector
• Reset logic: Active Low
• Reset timeout: 20ms Minimum
• Package / Case: SC-82A, SOT-343
• Operating temperature range: -40°C ~ 85°C (TA)
• Mounting type: Surface Mount
• Compliance certifications: ROHS3, REACH Unaffected

The substitute part S-80947CNNB-G9HT2U meets all these parameters identically, with the distinction that it carries an "Active" product status, making it suitable for new designs and ongoing production applications.

Parameter Comparison

Engineering Selection Recommendations

The S-80947CNNB-G9HT2U is the direct parametric equivalent for the S-80947CNNB-G9HT2G. Both parts are manufactured by ABLIC Inc. and share identical electrical and mechanical specifications. The primary distinction is product lifecycle status: the original part is designated "Not For New Designs," while the substitute carries "Active" status.

For applications currently using S-80947CNNB-G9HT2G, transition to S-80947CNNB-G9HT2U is supported by full compliance alignment, including ROHS3 certification and REACH unaffected status. No circuit redesign or board layout modification is required due to identical package specifications (SC-82A, SOT-343) and electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can S-80947CNNB-G9HT2U be used as a direct replacement for S-80947CNNB-G9HT2G?

A: Yes. Both parts are parametrically identical across all electrical and mechanical specifications, including voltage threshold (4.7V), output configuration (open drain or open collector), reset logic (active low), operating temperature range (-40°C ~ 85°C), and package type (SC-82A, SOT-343). No circuit modifications are required.

Q: Why is the original part marked "Not For New Designs"?

A: Product lifecycle management designates certain components as obsolete or transitioning out of production. The S-80947CNNB-G9HT2U maintains the same functionality with active production status, making it the recommended choice for new development.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1, Unlimited). Compliance certifications are fully aligned.

Q: What is the package compatibility between these parts?

A: Both parts use the SC-82A package in SOT-343 form factor with surface mount configuration. PCB footprints and assembly processes are identical.

Q: Is the reset timeout specification identical?

A: Yes. Both parts specify a 20ms minimum reset timeout with active-low reset logic, ensuring equivalent system-level behavior in power supervision applications.
