Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NTS10100EMFST3G is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Voltage - DC Reverse (Vr) (Max): 100 V minimum
• Current - Average Rectified (Io): 10 A minimum
• Voltage - Forward (Vf) (Max) @ If: 720 mV @ 10 A or lower
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Technology: Schottky

Mechanical & Environmental Equivalence Requirements:

• Package / Case: 8-PowerTDFN, 5 Leads
• Supplier Device Package: 5-DFN (5x6) (8-SOFL)
• Operating Temperature - Junction: -55°C minimum to 150°C maximum
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

The identified substitute part NRVTS10100MFST1G meets all electrical and mechanical equivalence criteria. Differences in product status, reverse leakage current, and maximum junction temperature do not preclude substitution when these parameters remain within acceptable design margins.

Engineering Selection Recommendations

Primary Substitute: NRVTS10100MFST1G

The NRVTS10100MFST1G is the direct functional equivalent for the obsolete NTS10100EMFST3G. Selection of this substitute is based on the following engineering criteria:

Electrical Compatibility: All critical electrical parameters are identical, including reverse voltage rating, forward current capacity, forward voltage drop, and switching speed. The substitute exhibits lower reverse leakage current (50 µA versus 70 µA), representing improved performance within the same functional class.

Thermal Performance: The substitute supports an extended maximum junction temperature range (-55°C to 175°C versus -55°C to 150°C), providing additional thermal margin for applications operating near the upper temperature boundary of the original specification.

Compliance & Certification: Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings. The substitute carries AEC-Q101 automotive qualification, indicating enhanced reliability validation through automotive-grade testing protocols.

Product Lifecycle Status: The substitute is classified as Last Time Buy, indicating controlled availability with defined procurement windows. The original part is Obsolete, making substitution necessary for continued component sourcing.

Packaging Consideration: The substitute is supplied in Tape & Reel format, standard for high-volume production environments. The original part was supplied in tube format. Design and assembly processes must accommodate this packaging difference.

Frequently Asked Questions (FAQ)

Q: Can NRVTS10100MFST1G be used as a direct replacement for NTS10100EMFST3G in existing designs?

A: Yes. Both parts are identical in electrical performance, package type, and mechanical dimensions. The substitute meets or exceeds all electrical specifications of the original part. Packaging format differs (Tape & Reel versus tube), requiring adjustment to component handling and placement procedures.

Q: What is the significance of the lower reverse leakage current in the substitute part?

A: The NRVTS10100MFST1G exhibits 50 µA reverse leakage at 100 V, compared to 70 µA for the NTS10100EMFST3G. This represents improved leakage performance and may reduce power dissipation in applications sensitive to reverse current characteristics. Both values remain within acceptable operating parameters for standard rectifier applications.

Q: Does the extended temperature range of NRVTS10100MFST1G affect circuit design?

A: The substitute supports operation to 175°C junction temperature, compared to 150°C for the original part. This extended range does not require design modification. Applications operating within the original -55°C to 150°C specification remain fully compatible. Applications requiring operation above 150°C benefit from the additional thermal margin.

Q: Are there any compliance or certification differences between the two parts?

A: Both parts are ROHS3 compliant with identical moisture sensitivity ratings. The substitute carries AEC-Q101 automotive qualification, indicating validation through automotive-grade reliability testing. This certification does not preclude use in non-automotive applications and represents an enhancement to the original part's qualification status.

Q: What is the impact of the different packaging format?

A: The original part is supplied in tube packaging; the substitute is supplied in Tape & Reel format. This difference affects component handling, storage, and automated placement procedures. Tape & Reel format is standard for high-volume production and offers improved efficiency in automated assembly environments. Manual or low-volume assembly processes may require adjustment to component feeding mechanisms.

Q: Is the substitute part currently available for procurement?

A: The NRVTS10100MFST1G is classified as Last Time Buy, indicating controlled availability with defined procurement windows. Procurement planning should account for this lifecycle status. The original NTS10100EMFST3G is Obsolete and no longer available through standard distribution channels.

Q: Can both parts be used interchangeably in the same production run?

A: Yes, provided that assembly processes accommodate the different packaging formats. Both parts are electrically and mechanically equivalent. Mixed sourcing from both parts is permissible when packaging handling procedures are standardized or when parts are processed through separate assembly batches.
