SD101AW-13 Equivalent & Substitute Parts

Part Overview

The SD101AW-13 is a Schottky rectifier diode manufactured by Diodes Incorporated, designed for surface mount applications in the SOD-123 package. This component operates at 60 V DC reverse voltage with a 15 mA average rectified current rating and a maximum forward voltage of 1 V at 15 mA. The SD101AW-13 is discontinued at DiGi Electronics, necessitating identification of equivalent and substitute components that maintain functional compatibility within specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution of the SD101AW-13 is determined by the following critical parameters: Schottky technology classification, 60 V maximum reverse voltage rating, 15 mA average rectified current capacity, 1 V maximum forward voltage at 15 mA, SOD-123 package form factor, and surface mount mounting type. Substitute parts must maintain these electrical specifications and physical package compatibility to ensure direct functional replacement without circuit redesign.

The substitute parts are grouped into two categories:

Parametric Equivalents: Parts that match all critical electrical parameters and package specifications of the SD101AW-13, differing only in packaging format (Tape & Reel versus bulk) or manufacturer source.

Manufacturer Recommended Substitutes: Parts that exceed the electrical specifications of the SD101AW-13 while maintaining backward compatibility through equal or superior ratings in voltage, current, and thermal performance.

Engineering Selection Recommendations

SD101AW-7-F (Diodes Incorporated): This part is a parametric equivalent to the SD101AW-13, matching all electrical specifications and package requirements. The primary difference is packaging format (Tape & Reel versus bulk) and active product status. This part is ROHS3 compliant and recommended for new designs requiring direct replacement of the discontinued SD101AW-13.

SD101AW-TP (Micro Commercial Co): This part is a parametric equivalent manufactured by an alternative source, maintaining identical electrical specifications and SOD-123 package compatibility. The part is ROHS3 compliant and active in production. Selection of this part is appropriate when supply chain diversification or alternative sourcing is required.

BAS70H,115 (Nexperia USA Inc.): This part exceeds the electrical specifications of the SD101AW-13 with a 70 V reverse voltage rating and 70 mA current capacity, providing design margin for applications requiring higher voltage or current headroom. The package is SOD-123F, which is mechanically compatible with SOD-123 footprints. The maximum junction temperature is 150°C compared to 125°C for the SD101AW-13. This part is ROHS3 compliant and active in production. Selection is appropriate for applications where enhanced electrical performance is beneficial.

Frequently Asked Questions (FAQ)

Q: Can SD101AW-7-F be used as a direct replacement for SD101AW-13?

A: Yes. The SD101AW-7-F maintains identical electrical specifications (60 V reverse voltage, 15 mA current, 1 V forward voltage) and SOD-123 package compatibility. The primary difference is packaging format (Tape & Reel) and active product status. No circuit modifications are required.

Q: What is the difference between SD101AW-TP and SD101AW-7-F?

A: Both parts are parametric equivalents with identical electrical specifications and SOD-123 package compatibility. The difference is manufacturer source: SD101AW-TP is manufactured by Micro Commercial Co, while SD101AW-7-F is manufactured by Diodes Incorporated. Both are ROHS3 compliant and active in production.

Q: Can BAS70H,115 replace SD101AW-13 in all applications?

A: BAS70H,115 is electrically superior with 70 V reverse voltage and 70 mA current capacity, providing backward compatibility for applications designed around the SD101AW-13 specifications. The SOD-123F package is mechanically compatible with SOD-123 footprints. However, the higher reverse leakage current (10 µA @ 70 V versus 200 nA @ 50 V) may affect circuit performance in applications sensitive to leakage current characteristics.

Q: What is the difference between SOD-123 and SOD-123F packages?

A: Both packages are surface mount form factors with compatible footprints. SOD-123F is a variant designation used by certain manufacturers. Physical dimensions and PCB land patterns are compatible, allowing direct substitution on existing circuit boards.

Q: Are all substitute parts RoHS compliant?

A: SD101AW-7-F, SD101AW-TP, and BAS70H,115 are all ROHS3 compliant. The original SD101AW-13 is RoHS non-compliant. Selection of compliant substitute parts is required for applications subject to RoHS regulations.

Q: Which substitute part should be selected for new designs?

A: SD101AW-7-F or SD101AW-TP are recommended for new designs requiring direct electrical and package compatibility with the SD101AW-13. Both parts are parametric equivalents with active product status and ROHS3 compliance. BAS70H,115 is recommended when enhanced voltage or current ratings provide design margin benefits.
