Engineering Selection Recommendations

The NTS12100EMFST1G is classified as obsolete product status. Both substitute parts, NTS12100EMFST3G and NTS12100MFST3G, are active products manufactured by onsemi and maintain complete electrical and mechanical parameter equivalence.

Selection between substitute parts is based on product status and compliance certifications:

NTS12100EMFST3G: Active product status. ROHS3 compliant, REACH unaffected, MSL 1 (Unlimited). Recommended for new designs and production applications requiring active product support.
NTS12100MFST3G: Active product status. ROHS3 compliant, REACH unaffected, MSL 1 (Unlimited). Recommended for new designs and production applications requiring active product support.

Both substitute parts are suitable for direct replacement in applications currently using the NTS12100EMFST1G, provided the circuit design operates within the specified electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Q: Can NTS12100EMFST3G or NTS12100MFST3G be used as direct replacements for NTS12100EMFST1G?

A: Yes. Both substitute parts maintain identical electrical ratings (100 V reverse voltage, 12 A average rectified current, 730 mV forward voltage at 12 A), identical fast recovery speed characteristics, identical reverse leakage current, and identical mechanical package specifications (5-DFN 5x6 8-SOFL). Direct substitution is electrically and mechanically compatible.

Q: What is the difference between NTS12100EMFST3G and NTS12100MFST3G?

A: Both parts are parametric equivalents with identical electrical specifications and package configurations. The difference in part number designation reflects manufacturing or packaging variations within onsemi's product line. Both are active products with equivalent compliance certifications.

Q: Why is the NTS12100EMFST1G classified as obsolete?

A: The NTS12100EMFST1G has been discontinued by onsemi. Active substitute parts with identical electrical and mechanical specifications are available to maintain design continuity.

Q: Are the substitute parts compatible with existing PCB layouts designed for NTS12100EMFST1G?

A: Yes. The substitute parts use the identical 5-DFN (5x6) (8-SOFL) package with 8-PowerTDFN, 5 Leads configuration. PCB footprints, land patterns, and mounting procedures remain unchanged.

Q: Do the substitute parts meet the same compliance requirements?

A: Yes. Both NTS12100EMFST3G and NTS12100MFST3G are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original part.

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

A: The operating junction temperature range is -55°C to 150°C for all parts, including the original NTS12100EMFST1G and both substitute parts.
