Key Parameters

Substitute Part Grouping Explanation

Substitution of the NRVB860MFST3G is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 60 V
• Current - Average Rectified (Io): 8 A
• Package / Case: 8-PowerTDFN, 5 Leads (5-DFN 5x6)
• Mounting Type: Surface Mount
• Technology: Schottky
• Operating Temperature Range: -55°C to 175°C

Allowable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: Lower values are acceptable (improved performance)
• Current - Reverse Leakage @ Vr: Lower values are acceptable (improved performance)
• Product Status: Substitutes may have different lifecycle status
• Packaging Format: Tape & Reel (TR) is compatible with bulk packaging for equivalent electrical function

The NRVTS860EMFST1G meets all mandatory matching criteria and demonstrates improved electrical characteristics in forward voltage drop and reverse leakage current, making it a direct functional substitute.

Parameter Comparison

Engineering Selection Recommendations

The NRVTS860EMFST1G is a direct functional substitute for the NRVB860MFST3G based on electrical and mechanical parameter equivalence. Selection between these parts is determined by application requirements and supply chain considerations:

Primary Substitute: NRVTS860EMFST1G

This part is recommended for new designs and ongoing procurement due to:

• Identical voltage and current ratings (60 V, 8 A)
• Identical package and pinout (5-DFN 5x6, 8-PowerTDFN)
• Improved electrical performance (lower forward voltage drop of 620 mV vs. 800 mV; lower reverse leakage of 45 µA vs. 150 µA)
• Extended product lifecycle status (Last Time Buy vs. Obsolete)
• Automotive-grade qualification (AEC-Q101) providing enhanced reliability documentation
• Same manufacturer (onsemi) ensuring design continuity

The substitute part's automotive qualification and improved electrical characteristics make it suitable for applications requiring higher reliability standards or lower power dissipation. The lower forward voltage drop reduces thermal load in rectification circuits. The lower reverse leakage current improves circuit performance in applications sensitive to leakage current.

For applications where the original NRVB860MFST3G specifications are critical, the NRVTS860EMFST1G operates within a superior performance envelope and presents no functional incompatibility.

Frequently Asked Questions (FAQ)

Q: Can the NRVTS860EMFST1G be used as a direct replacement for the NRVB860MFST3G in existing designs?

A: Yes. Both parts share identical voltage ratings (60 V), current ratings (8 A), package type (5-DFN 5x6), pinout configuration, and operating temperature range (-55°C to 175°C). The substitute part demonstrates improved electrical characteristics and is electrically and mechanically compatible.

Q: What is the difference in forward voltage drop between these parts?

A: The NRVB860MFST3G has a maximum forward voltage of 800 mV at 8 A, while the NRVTS860EMFST1G has a maximum forward voltage of 620 mV at 8 A. The substitute part exhibits lower forward voltage drop, resulting in reduced power dissipation and improved efficiency in rectification applications.

Q: What is the difference in reverse leakage current?

A: The NRVB860MFST3G has a reverse leakage current of 150 µA at 60 V, while the NRVTS860EMFST1G has a reverse leakage current of 45 µA at 60 V. The substitute part exhibits significantly lower reverse leakage, which is beneficial in applications where leakage current must be minimized.

Q: Are the packages identical?

A: Yes. Both parts use the 8-PowerTDFN package with 5 leads in a 5x6 mm footprint (5-DFN 5x6, 8-SOFL). PCB layouts and thermal management designs are directly compatible.

Q: What does "Last Time Buy" status mean for the substitute part?

A: Last Time Buy indicates that the NRVTS860EMFST1G has a defined end-of-life date, after which the manufacturer will no longer produce or support the part. This status provides a window for procurement before discontinuation. Current inventory is available (1050 pcs in stock).

Q: Does the automotive qualification of the substitute part affect its use in non-automotive applications?

A: No. Automotive qualification (AEC-Q101) indicates enhanced reliability testing and documentation standards. Parts qualified to automotive standards are suitable for all applications, including non-automotive use. The qualification represents a superset of standard reliability requirements.

Q: Are there any compliance differences between these parts?

A: The main part (NRVB860MFST3G) is specified as RoHS3 compliant and REACH unaffected. Compliance information for the substitute part (NRVTS860EMFST1G) is not provided in the available data. Verify compliance documentation with the manufacturer if regulatory compliance is a design requirement.

Q: What is the difference in packaging format?

A: The main part is supplied in standard packaging, while the substitute part is supplied in Tape & Reel (TR) format. Both formats contain identical components; the difference is in the delivery and handling method. Tape & Reel format is standard for automated assembly processes.
