Equivalent & Substitute Parts for VS-1N3213

Part Overview

The VS-1N3213 is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. This component operates at 500 V DC reverse voltage with 15 A average rectified current in a DO-203AB (DO-5) chassis stud mount package. The part is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level. Substitute parts are identified when equivalent electrical and mechanical parameters are required for circuit applications where the original part number becomes unavailable or when design specifications permit operation at higher voltage or current ratings within the same package form factor.

Substitute Part Grouping Explanation

Substitute parts for the VS-1N3213 are identified based on the following criteria:

Mechanical Compatibility: The substitute part must use the identical package form factor (DO-203AB, DO-5, Stud Mount) to ensure direct physical replacement without circuit board modification.

Electrical Compatibility: The substitute part must maintain or exceed the voltage and current ratings of the original part. Specifically:

DC Reverse Voltage (Vr) must be equal to or greater than 500 V
Average Rectified Current (Io) must be equal to or greater than 15 A
Forward voltage characteristics must be compatible with circuit operation
Recovery speed classification must remain Standard Recovery

Compliance & Status: The substitute part must maintain Active product status and ROHS3 compliance to ensure continued availability and regulatory conformance.

The VS-40HF80 qualifies as a substitute part because it shares the identical DO-203AB package, maintains Chassis Stud Mount configuration, exceeds both voltage (800 V vs. 500 V) and current (40 A vs. 15 A) ratings, and retains ROHS3 compliance and Active status.

Engineering Selection Recommendations

Primary Selection: The VS-1N3213 remains the primary component choice when circuit specifications require exactly 500 V reverse voltage and 15 A average rectified current. This part is Active status with ROHS3 compliance and maintains full regulatory conformance.

Substitute Selection: The VS-40HF80 is a qualified substitute when the original VS-1N3213 is unavailable. The substitute part provides higher voltage and current ratings (800 V / 40 A) within the identical DO-203AB package, ensuring mechanical and thermal compatibility. Both parts share identical recovery speed classification and maintain ROHS3 compliance. The extended operating temperature range of the VS-40HF80 (-65°C to 190°C versus -65°C to 175°C) provides additional thermal margin.

Inventory Consideration: The VS-40HF80 maintains higher stock availability (5069 pieces versus 1069 pieces for the VS-1N3213), supporting supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the VS-40HF80 be used as a direct replacement for the VS-1N3213?

A: Yes. Both parts use the identical DO-203AB (DO-5) Stud Mount package. The VS-40HF80 provides higher voltage (800 V) and current (40 A) ratings, making it electrically compatible for applications designed for the VS-1N3213 specifications.

Q: What are the key differences between these two diodes?

A: The VS-40HF80 exceeds the VS-1N3213 in three parameters: DC Reverse Voltage (800 V vs. 500 V), Average Rectified Current (40 A vs. 15 A), and Operating Temperature Range (-65°C to 190°C vs. -65°C to 175°C). Both maintain identical package form factor, recovery speed classification, and compliance status.

Q: Are there any circuit design considerations when substituting the VS-40HF80 for the VS-1N3213?

A: No design modifications are required. The higher ratings of the VS-40HF80 provide additional safety margin without affecting circuit operation. The forward voltage at rated current is comparable (1.5 V @ 15 A for VS-1N3213 versus 1.3 V @ 125 A for VS-40HF80).

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the VS-1N3213 and VS-40HF80 are ROHS3 compliant, REACH unaffected, and classified as Active product status. Both carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: What is the moisture sensitivity level for these components?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can the VS-1N3213 be used as a substitute for the VS-40HF80?

A: No. The VS-1N3213 has lower voltage (500 V) and current (15 A) ratings than the VS-40HF80 (800 V / 40 A). Substitution in the reverse direction would violate electrical specifications for applications requiring the higher ratings of the VS-40HF80.
