Substitute Part Grouping Explanation

Substitution logic for the DSS16-01AS-TUB is based on the following criteria:

Primary Equivalent (Manufacturer Recommended): DSS16-01AS-TRL maintains identical electrical specifications (100V, 16A, 790 mV forward voltage) and mechanical packaging (TO-263AA). The only difference is packaging format (Tape & Reel versus Tube), making this a direct functional equivalent with Active product status.

Secondary Substitutes (Reduced Current Rating): MBRB8H100T4G and STPS8H100G-TR are classified as similar substitutes due to reduced average rectified current (8A versus 16A). Both maintain the 100V reverse voltage rating, fast recovery speed characteristic, Surface Mount D2PAK package compatibility, and ROHS3 compliance. These parts are suitable for applications where the 16A current requirement can be reduced or where parallel configurations are acceptable. Both substitutes carry Active product status.

Substitution eligibility is determined by:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 100V
Package / Case: Must be compatible TO-263 family (D2PAK)
Mounting Type: Surface Mount
Technology: Schottky
Speed: Fast Recovery characteristic
Compliance: ROHS3 Compliant

Engineering Selection Recommendations

For Direct Replacement: DSS16-01AS-TRL is the manufacturer-recommended equivalent and primary selection for designs currently using DSS16-01AS-TUB. This part maintains identical electrical performance (100V, 16A, 790 mV forward voltage) and mechanical compatibility while offering Active product status and improved long-term availability. The transition from Tube to Tape & Reel packaging does not affect electrical or thermal performance.

For Current-Reduced Applications: MBRB8H100T4G (onsemi) and STPS8H100G-TR (STMicroelectronics) are suitable substitutes where circuit design permits operation at 8A average rectified current. Both parts maintain 100V reverse voltage rating, fast recovery characteristics, and D2PAK package compatibility. MBRB8H100T4G offers lower reverse leakage current (4.5 µA versus 500 µA) and extended lower operating temperature range (-65°C). STPS8H100G-TR provides equivalent performance with STMicroelectronics supply chain support.

Compliance Considerations: All recommended parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory continuity for existing designs. Moisture Sensitivity Level (MSL) 1 (Unlimited) is consistent across all options, eliminating moisture handling constraints.

Frequently Asked Questions (FAQ)

Q: Can DSS16-01AS-TRL be used as a direct replacement for DSS16-01AS-TUB?

A: Yes. DSS16-01AS-TRL is the manufacturer-recommended equivalent with identical electrical specifications (100V, 16A, 790 mV forward voltage) and mechanical packaging (TO-263AA). The only difference is packaging format (Tape & Reel versus Tube), which does not affect circuit performance or thermal characteristics.

Q: What is the primary limitation when using MBRB8H100T4G or STPS8H100G-TR as substitutes?

A: The average rectified current rating is reduced from 16A to 8A. These substitutes are applicable only in designs where the circuit load current does not exceed 8A, or where parallel diode configurations are implemented to achieve higher current capacity.

Q: Are the substitute parts (MBRB8H100T4G and STPS8H100G-TR) pin-compatible with the original DSS16-01AS-TUB?

A: Yes. All parts use the TO-263-3 D2PAK package with identical pin configuration (2 Leads + Tab), ensuring direct PCB compatibility without layout modifications.

Q: Do the substitute parts maintain the same forward voltage characteristics?

A: The substitute parts (MBRB8H100T4G and STPS8H100G-TR) have a lower forward voltage specification of 710 mV @ 8A compared to the original 790 mV @ 15A. This lower forward voltage results in reduced power dissipation in applications operating at or below 8A current levels.

Q: What is the difference in reverse leakage current between the main part and substitutes?

A: The original DSS16-01AS-TUB specifies 500 µA reverse leakage @ 100V, while MBRB8H100T4G and STPS8H100G-TR specify 4.5 µA @ 100V. The substitutes exhibit significantly lower reverse leakage, which may improve circuit performance in sensitive applications.

Q: Are all recommended parts compliant with current environmental regulations?

A: Yes. DSS16-01AS-TRL, MBRB8H100T4G, and STPS8H100G-TR are all ROHS3 Compliant and REACH Unaffected, maintaining regulatory compliance for new designs and existing applications.

Q: What is the operating temperature range difference between substitute parts?

A: DSS16-01AS-TUB and DSS16-01AS-TRL specify -55°C to 175°C. MBRB8H100T4G extends the lower limit to -65°C, while STPS8H100G-TR specifies 175°C maximum without a defined lower limit. Temperature range selection depends on application requirements.
