Electrical Technology:

• Both components utilize Schottky diode technology, preserving the functional characteristics required in the original design

Frequently Asked Questions (FAQ)

Q: Why is the VS-S1498 no longer available?

A: The VS-S1498 has reached end-of-life status and is classified as obsolete by the manufacturer. Vishay General Semiconductor - Diodes Division has transitioned this product line to active alternatives.

Q: Is the V20PW45-M3/I a direct replacement for the VS-S1498?

A: The V20PW45-M3/I is the manufacturer-designated substitute. Both components share identical compliance certifications (ROHS3, MSL 1) and Schottky diode technology. Physical package differences may require PCB layout evaluation.

Q: What is the difference between the VS-S1498 and V20PW45-M3/I packaging?

A: The V20PW45-M3/I is specified as a surface mount component in SlimDPAK package (TO-252-3, DPAK with 2 leads plus tab). The VS-S1498 packaging specification is not provided in available documentation. PCB compatibility assessment is required during design transition.

Q: Are there additional substitutes beyond V20PW45-M3/I?

A: The V20PW45-M3/I documentation indicates secondary alternatives including V20PW45HM3/I and STPS1045B-TR. These represent extended substitute options within the Vishay product portfolio and external manufacturer equivalents.

Q: Does the V20PW45-M3/I maintain the same compliance certifications?

A: Yes. The V20PW45-M3/I carries ROHS3 compliance and MSL 1 (Unlimited) rating, matching the VS-S1498 certifications. REACH status is documented as REACH Unaffected for the substitute part.

Q: What is the current inventory status for the V20PW45-M3/I?

A: The V20PW45-M3/I maintains active inventory with 4860 pieces in stock as new original components, ensuring procurement availability for design implementation.
