Substitute Part Grouping Explanation

Substitution of the S210 is determined by the following critical parameters:

Voltage Rating (Vr): The substitute must support a minimum of 100V reverse voltage to maintain circuit protection and reliability.

Current Rating (Io): The substitute must support a minimum of 2A average rectified current to handle the intended load without thermal stress or performance degradation.

Package Type: All substitutes must use the DO-214AA (SMB) surface mount package to ensure mechanical and thermal compatibility with existing PCB layouts and assembly processes.

Technology: All substitutes must employ Schottky diode technology to maintain fast recovery characteristics and forward voltage performance consistent with the original design.

Mounting Type: Surface mount configuration is required for compatibility with automated assembly equipment and PCB footprints.

Substitutes are grouped into two categories:

Direct Equivalents (100V, 2A): Parts meeting or exceeding all electrical specifications with identical current and voltage ratings.

Functional Alternatives (100V, ≤2A or ≥100V, 2A): Parts with compatible voltage ratings but lower current ratings, suitable for applications where the full 2A capacity is not required, or higher current ratings providing design margin.

Engineering Selection Recommendations

Primary Direct Equivalents (100V, 2A Rating):

The following parts provide direct electrical and mechanical equivalence to the S210 and are recommended as primary substitutes:

MBRS2H100T3G (onsemi): Active product status with identical voltage and current ratings. Forward voltage of 790 mV at 2A is lower than the S210 specification, reducing power dissipation. Reverse leakage of 8 µA is significantly lower, improving efficiency. Maximum junction temperature of 175°C exceeds the S210 specification, providing thermal margin. ROHS3 compliant.

B2100-13-F (Diodes Incorporated): Active product with matching 100V/2A specifications. Forward voltage of 790 mV and reverse leakage of 7 µA provide performance improvements over the S210. Maximum junction temperature of 150°C is adequate for most applications. ROHS3 compliant.

SS2H10-E3/52T (Vishay General Semiconductor - Diodes Division): Active product with 100V/2A rating. Forward voltage of 790 mV and reverse leakage of 10 µA deliver improved performance characteristics. Maximum junction temperature of 175°C provides thermal headroom. ROHS3 compliant.

MB210_R1_00001 (Panjit International Inc.): Active product with 100V/2A specifications. Forward voltage of 800 mV is closest to the S210 specification. Maximum junction temperature of 175°C supports extended operating ranges. ROHS3 compliant.

Secondary Alternatives (100V, 3A Rating):

SK310B-LTP (Micro Commercial Co): Active product with 100V rating and 3A current capacity. Provides design margin above the 2A requirement. Forward voltage of 850 mV matches the S210 specification exactly. Suitable for applications requiring higher current headroom or thermal margin. ROHS3 compliant.

Functional Alternatives (100V, 1A Rating):

The following 1A-rated parts are suitable only for applications where the full 2A capacity is not required:

MBRS1100T3G (onsemi): Active product with 100V/1A rating. Lower current capacity limits use to applications drawing ≤1A. ROHS3 compliant.

B1100LB-13-F (Diodes Incorporated): Active product with 100V/1A rating. Suitable for reduced-current applications only. ROHS3 compliant.

STPS1H100U and STPS1H100UY (STMicroelectronics): Active products with 100V/1A rating. STPS1H100UY includes automotive-grade qualification. Both suitable for 1A maximum applications. ROHS3 compliant.

Not Recommended:

MBRS190T3G (onsemi): Voltage rating of 90V is below the S210 specification and does not provide adequate circuit protection for 100V applications.

Frequently Asked Questions (FAQ)

Q: Can the MBRS2H100T3G directly replace the S210 in existing designs?

A: Yes. The MBRS2H100T3G provides identical voltage (100V) and current (2A) ratings with improved electrical characteristics including lower forward voltage and reverse leakage. The DO-214AA package ensures mechanical and thermal compatibility. No PCB layout modifications are required.

Q: What is the difference between the 2A-rated substitutes (MBRS2H100T3G, B2100-13-F, SS2H10-E3/52T, MB210_R1_00001)?

A: All four parts meet the 100V/2A specification. Primary differences are forward voltage (790-800 mV), reverse leakage (7-50 µA), and maximum junction temperature (150-175°C). MBRS2H100T3G, B2100-13-F, and SS2H10-E3/52T offer superior reverse leakage performance. MB210_R1_00001 provides the closest forward voltage match to the S210. Selection depends on thermal requirements and leakage current sensitivity in the application.

Q: Can I use a 1A-rated diode (STPS1H100UY, B1100LB-13-F) instead of the 2A S210?

A: Only if the circuit design draws a maximum of 1A. Using a 1A-rated part in a 2A application will cause thermal stress, reduced reliability, and potential component failure. Verify actual circuit current requirements before substituting with lower-rated parts.

Q: Why is the MBRS190T3G listed as a substitute if it has a 90V rating?

A: The MBRS190T3G does not meet the S210 specification and is not recommended for direct substitution. A 90V rating is insufficient for 100V circuit protection. This part is included in the comparison table for reference only and should not be selected for applications requiring 100V blocking capability.

Q: What is the significance of the SK310B-LTP having a 3A rating?

A: The SK310B-LTP provides 50% additional current capacity above the S210 specification. This part is suitable for applications where design margin or future current growth is anticipated. The higher current rating does not affect compatibility with existing 2A designs; the part will operate within its safe operating area at 2A or below.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification, matching the S210 environmental standard. All parts are also REACH Unaffected and classified as EAR99 for export control purposes.

Q: Does package type affect substitution?

A: No. All substitute parts use the DO-214AA (SMB) surface mount package, ensuring identical PCB footprint compatibility, solder reflow profiles, and thermal characteristics. Package type is not a differentiating factor among these substitutes.

Q: What is the operating temperature range difference between the S210 and active substitutes?

A: The S210 operates from -65°C to 125°C. Most active substitutes (MBRS2H100T3G, SS2H10-E3/52T, MB210_R1_00001, STPS1H100U, STPS1H100UY) extend the maximum junction temperature to 175°C, providing 50°C additional thermal margin. B2100-13-F and SK310B-LTP are rated to 150°C. Extended temperature ranges improve reliability in high-temperature environments.

Q: Is the STPS1H100UY automotive-qualified?

A: Yes. The STPS1H100UY carries automotive-grade qualification (Series Q designation). This part is suitable for automotive applications requiring AEC-Q101 compliance. However, its 1A current rating limits use to lower-current circuits. For automotive applications requiring 2A capacity, MBRS2H100T3G or SS2H10-E3/52T are recommended.
