Substitute Part Grouping Explanation

Substitution eligibility for the VS-10TQ035PBF is determined by the following critical parameters:

Primary Substitution Criteria:

Technology: Schottky diode
Current - Average Rectified (Io): 10A minimum
Voltage - DC Reverse (Vr): Equal to or greater than 35V
Package / Case: TO-220-2 (TO-220AC supplier package)
Mounting Type: Through Hole
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Compliance Requirements:

RoHS3 Compliant
REACH Unaffected
Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all primary criteria and compliance requirements are classified as direct substitutes. Parts exceeding voltage ratings while maintaining all other parameters are classified as functional upgrades suitable for applications with higher voltage margins.

Engineering Selection Recommendations

VS-10TQ035-M3 (Direct Substitute)

The VS-10TQ035-M3 is a direct substitute for the VS-10TQ035PBF. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical voltage and current ratings (35V, 10A). The VS-10TQ035-M3 is currently in active production status with significantly higher inventory availability (3980 Pcs versus 933 Pcs). Both parts meet ROHS3 compliance, REACH unaffected status, and MSL 1 requirements. The VS-10TQ035-M3 demonstrates improved reverse leakage characteristics (2 mA @ 35V versus 6 mA @ 35V) and lower forward voltage drop (670 mV @ 20A versus 760 mV @ 10A), making it the preferred choice for new designs and ongoing procurement.

STPS1045D (Functional Upgrade)

The STPS1045D is manufactured by STMicroelectronics and provides a higher voltage rating (45V versus 35V) while maintaining the 10A current specification and TO-220-2 package. This part is suitable for applications requiring additional voltage margin or operating in higher voltage environments. The STPS1045D exhibits superior forward voltage characteristics (600 mV @ 10A) and is available in significantly larger quantities (55200 Pcs). Both parts meet ROHS3 compliance and MSL 1 requirements. The STPS1045D is recommended for applications where the 35V rating of the original part represents a design constraint or where higher voltage headroom is beneficial.

Frequently Asked Questions (FAQ)

Q: Can VS-10TQ035-M3 be used as a direct replacement for VS-10TQ035PBF?

A: Yes. Both parts are Schottky diodes with identical voltage (35V) and current (10A) ratings, TO-220-2 package configuration, and through-hole mounting. Both meet ROHS3 compliance and MSL 1 requirements. The VS-10TQ035-M3 is currently in active production status, whereas the VS-10TQ035PBF is discontinued.

Q: What is the difference between VS-10TQ035-M3 and STPS1045D?

A: The primary difference is voltage rating: VS-10TQ035-M3 is rated for 35V DC reverse voltage, while STPS1045D is rated for 45V. Both maintain 10A current capacity and TO-220-2 package. The STPS1045D is manufactured by STMicroelectronics rather than Vishay. Current leakage and forward voltage characteristics differ between the two parts.

Q: Is STPS1045D compatible with circuits designed for VS-10TQ035PBF?

A: STPS1045D is functionally compatible in applications where the circuit voltage does not exceed 35V. The higher 45V rating provides additional voltage margin. However, the different manufacturer and improved electrical characteristics (lower forward voltage, lower leakage) should be verified against specific circuit requirements before implementation.

Q: Are all three parts available in the same packaging?

A: Yes. All three parts use TO-220-2 package configuration with TO-220AC supplier device package designation and through-hole mounting type. Physical footprint and thermal characteristics are compatible.

Q: Which substitute part has the best availability?

A: STPS1045D has the highest inventory availability at 55200 Pcs. VS-10TQ035-M3 has 3980 Pcs available. The original VS-10TQ035PBF has 933 Pcs remaining but is discontinued.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. VS-10TQ035PBF, VS-10TQ035-M3, and STPS1045D all meet ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity requirements.
