Substitute Part Grouping Explanation

Substitution of the V2FM12HM3/I is determined by strict equivalence across the following electrical and mechanical parameters:

Voltage Rating: 120 V DC reverse voltage (Vr)
Current Rating: 2 A average rectified current (Io)
Forward Voltage Drop: 960 mV maximum at 2 A forward current
Reverse Leakage Current: 65 µA at 120 V
Junction Capacitance: 130 pF at 4 V, 1 MHz
Recovery Speed: Fast recovery ≤ 500 ns for currents > 200 mA
Package: DO-219AB surface mount package
Temperature Range: -40°C to 175°C junction operating temperature
Technology: Schottky diode

All substitute parts listed maintain these electrical specifications and mechanical compatibility. Differences in part numbering reflect variations in packaging configuration (tape & reel designation) or qualification status (automotive grade), not functional performance.

Engineering Selection Recommendations

All three parts—V2FM12HM3/I, V2FM12-M3/H, and V2FM12HM3/H—are active production components from Vishay General Semiconductor - Diodes Division with identical electrical and mechanical specifications. Selection between these parts is based on the following criteria:

V2FM12HM3/I (Primary Part): Automotive-grade diode with AEC-Q101 qualification. Suitable for applications requiring automotive compliance and qualification documentation. Current inventory: 969 pieces.

V2FM12-M3/H (Substitute): Industrial-grade equivalent without automotive qualification. Maintains all electrical parameters and DO-219AB package compatibility. Highest inventory availability at 10,237 pieces. Suitable for non-automotive applications where automotive qualification is not required.

V2FM12HM3/H (Substitute): Automotive-grade diode with AEC-Q101 qualification, functionally identical to V2FM12HM3/I. Inventory: 8,521 pieces. Provides alternative sourcing for automotive applications.

All parts comply with RoHS3 and REACH regulations. Selection should be based on application requirements (automotive vs. industrial), inventory availability, and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can V2FM12-M3/H be used as a direct replacement for V2FM12HM3/I in automotive applications?

A: V2FM12-M3/H maintains identical electrical specifications and package compatibility. However, it lacks automotive-grade qualification and AEC-Q101 certification. Use in automotive applications depends on specific design requirements and qualification mandates. For applications requiring automotive compliance documentation, V2FM12HM3/H is the appropriate substitute.

Q: What is the difference between V2FM12HM3/I and V2FM12HM3/H?

A: Both parts are automotive-grade Schottky diodes with AEC-Q101 qualification and identical electrical parameters. The difference lies in packaging configuration or moisture sensitivity level designation. Both are suitable for automotive applications requiring qualification.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the DO-219AB (SMF) surface mount package with identical pinout and footprint. They are mechanically and electrically interchangeable at the board level.

Q: What are the key electrical parameters that define substitution for this diode?

A: Substitution is determined by: 120 V reverse voltage rating, 2 A average rectified current, 960 mV forward voltage drop at 2 A, 65 µA reverse leakage current at 120 V, 130 pF junction capacitance, and fast recovery speed ≤ 500 ns. All substitute parts maintain these specifications.

Q: Is moisture sensitivity a factor in selecting between these parts?

A: V2FM12-M3/H specifies MSL 1 (Unlimited). V2FM12HM3/I and V2FM12HM3/H also specify MSL 1 (Unlimited). Moisture sensitivity is not a differentiating factor for these parts.

Q: Which part should be selected for new designs?

A: For automotive applications, select V2FM12HM3/I or V2FM12HM3/H based on availability and supply chain strategy. For industrial applications without automotive qualification requirements, V2FM12-M3/H is suitable. All parts are active production components with stable supply.
