Substitute Part Grouping Explanation

Substitute parts for the STB30100C are identified based on strict electrical and mechanical compatibility criteria. The following parameters establish substitution validity:

Primary Compatibility Criteria:

• Diode Configuration: 1 Pair Common Cathode (identical topology required)
• Technology: Schottky (same semiconductor technology)
• Voltage - DC Reverse (Vr) (Max): 100 V (equal or higher rating acceptable)
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab), TO-263AB (identical mechanical footprint)
• Mounting Type: Surface Mount (identical assembly method)
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io) (performance class match)

Secondary Compatibility Criteria:

• RoHS Status: ROHS3 Compliant (regulatory alignment)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (handling compatibility)

The STPS10H100CG-TR meets all primary and secondary criteria, establishing it as a valid substitute for the STB30100C.

Engineering Selection Recommendations

STB30100C (Primary Part)

The STB30100C remains the primary selection when specified in design documentation or when SMC Diode Solutions supply chain is preferred. This part is Active in product status, ROHS3 Compliant, and REACH Affected. Current inventory availability is 1,675 pieces in Tape & Reel packaging.

STPS10H100CG-TR (Substitute Part)

The STPS10H100CG-TR is a valid substitute when supply constraints affect STB30100C availability. This STMicroelectronics part maintains identical electrical configuration, reverse voltage rating, package footprint, and thermal speed classification. The substitute demonstrates improved electrical characteristics including lower reverse leakage current (3.5 µA versus 500 µA) and higher maximum junction temperature (175°C versus 150°C). The part is Active in product status, ROHS3 Compliant, and REACH Unaffected. Current inventory availability is 4,960 pieces in Cut Tape and Digi-Reel packaging.

Both parts satisfy regulatory compliance requirements and are suitable for direct substitution in Surface Mount TO-263-3 D2PAK applications requiring 100 V Schottky diode arrays with common cathode configuration.

Frequently Asked Questions (FAQ)

Q: Can STPS10H100CG-TR be used as a direct replacement for STB30100C?

A: Yes. Both parts share identical diode configuration (1 Pair Common Cathode), Schottky technology, 100 V reverse voltage rating, TO-263-3 D2PAK package footprint, and Fast Recovery speed classification. The parts are mechanically and electrically interchangeable at the board level.

Q: What are the key differences between these parts?

A: The STPS10H100CG-TR specifies a 5 A average rectified current rating, while the STB30100C does not specify this parameter. The substitute exhibits lower reverse leakage current (3.5 µA versus 500 µA at 100 V) and a higher maximum junction temperature (175°C versus 150°C). Forward voltage characteristics differ due to different rated current levels (730 mV @ 5 A versus 750 mV @ 15 A).

Q: Are the packages identical?

A: Yes. Both parts use the TO-263-3 D2PAK package with 2 leads plus tab configuration. The mechanical footprint, lead spacing, and mounting requirements are identical, allowing direct PCB substitution without layout modifications.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape and Digi-Reel packaging provide components on cut tape segments or alternative reel formats, suitable for lower-volume or mixed-component assembly operations. Both packaging formats contain identical components.

Q: Are both parts RoHS compliant?

A: Yes. Both STB30100C and STPS10H100CG-TR are ROHS3 Compliant, meeting Restriction of Hazardous Substances requirements for lead-free manufacturing and restricted substance limitations.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: Both parts have MSL 1 (Unlimited), indicating unlimited shelf life without moisture bake-out requirements. Standard dry storage conditions apply.

Q: Can I use STPS10H100CG-TR in applications requiring the full 15 A current capability of STB30100C?

A: The STPS10H100CG-TR is rated for 5 A average rectified current. Application requirements must be evaluated against this rating. If the application requires sustained current above 5 A, the STB30100C or alternative parts with higher current ratings must be selected.
