VS-25F40M Equivalent & Substitute Parts

Part Overview

The VS-25F40M is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This component is rated for 400 V DC reverse voltage with an average rectified current of 25 A and features a chassis stud mount configuration in the DO-203AA (DO-4) package. The part maintains Active product status and is RoHS3 compliant.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same product category. Alternative part numbers may be required due to inventory availability, supply chain considerations, or specific procurement requirements while maintaining identical functional performance.

Substitute Part Grouping Explanation

Substitute parts for the VS-25F40M are identified based on strict equivalence of electrical and mechanical parameters. The substitution criteria are:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 25 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 78 A
• Speed: Standard Recovery >500ns, > 200mA (Io)

Mechanical Parameters:

• Mounting Type: Chassis, Stud Mount
• Package / Case: DO-203AA, DO-4, Stud
• Operating Temperature - Junction: -65°C to 175°C

Compliance Parameters:

• Technology: Standard
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Parts are grouped as substitutes only when all parameters listed above are identical to the main part number. No parameter deviation is permitted for substitution classification.

Parameter Comparison

Engineering Selection Recommendations

Both the VS-25F40M and VS-25F40 are Active products manufactured by Vishay General Semiconductor - Diodes Division and maintain identical electrical and mechanical specifications. Both parts are ROHS3 compliant and operate across the same temperature range of -65°C to 175°C.

Selection between these parts is based on availability and procurement requirements. The VS-25F40M currently maintains 1138 pieces in stock, while the VS-25F40 maintains 832 pieces in stock. Both parts satisfy the same functional requirements for 400 V, 25 A general-purpose rectification applications in DO-203AA stud mount configurations.

Frequently Asked Questions (FAQ)

Q: Can VS-25F40 be used as a direct replacement for VS-25F40M?

A: Yes. The VS-25F40 is a parametric equivalent with identical electrical ratings (400 V, 25 A), forward voltage characteristics (1.3 V @ 78 A), recovery speed (Standard >500ns), mechanical mounting (Chassis, Stud Mount), package type (DO-203AA, DO-4), and operating temperature range (-65°C to 175°C). Both parts are ROHS3 compliant and Active products.

Q: Are there any differences in the DO-203AA package between these parts?

A: No. Both the VS-25F40M and VS-25F40 use the identical DO-203AA (DO-4) stud mount package. Physical dimensions, mounting interface, and thermal characteristics are equivalent.

Q: What is the significance of the "M" designation in VS-25F40M?

A: The "M" designation does not represent a functional or electrical difference. Both VS-25F40M and VS-25F40 share the same base product number (25F40) and maintain identical electrical and mechanical parameters.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both the VS-25F40M and VS-25F40 operate across a junction temperature range of -65°C to 175°C, making them suitable for applications requiring extended temperature performance within this range.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both maintain Moisture Sensitivity Level (MSL) 1 (Unlimited).
