Substitute Part Grouping Explanation

Substitute parts for the ES2BAHR3G are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents share identical or functionally equivalent electrical specifications and package form factors. These parts maintain the same voltage rating (100 V), current rating (2 A), package type (DO-214AC SMA), and fast recovery characteristics (≤500 ns). Parametric equivalents include ES2BA (Good-Ark Semiconductor), ES2BA R3G (Taiwan Semiconductor Corporation), and ES2BAH (Taiwan Semiconductor Corporation). These components are direct functional replacements with no circuit redesign required.

Similar Parts meet the voltage and package requirements but differ in current rating, diode technology, or other secondary parameters. These parts are suitable for applications where the 2 A current rating is not fully utilized or where Schottky technology characteristics are acceptable. Similar parts include the B1100 series (Diodes Incorporated) at 1 A rating and B2100 series (Diodes Incorporated) at 2 A rating with Schottky technology, as well as CDBA1100-HF (Comchip Technology) at 1 A rating.

Substitution logic is based on the following key parameters:

Voltage - DC Reverse (Vr) (Max): 100 V minimum
Current - Average Rectified (Io): 2 A for parametric equivalents; 1 A or 2 A for similar parts
Package / Case: DO-214AC (SMA) for parametric equivalents; DO-214AC (SMA), DO-214AA (SMB), or DO-221AC (SMAF) for similar parts
Technology: Standard (fast recovery) for parametric equivalents; Schottky for similar parts
Operating Temperature - Junction: -55°C to 150°C minimum for parametric equivalents

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

ES2BAH (Taiwan Semiconductor Corporation) is the primary recommended substitute. This part is active in production, maintains identical electrical specifications to the ES2BAHR3G (100 V, 2 A, 950 mV forward voltage, 35 ns recovery time), operates across the same temperature range (-55°C to 150°C), carries AEC-Q101 automotive qualification, and is packaged in DO-214AC (SMA). The part is ROHS3 compliant and REACH unaffected, matching the compliance profile of the original component.

ES2BA (Good-Ark Semiconductor) is an alternative parametric equivalent with active production status. This part meets the 100 V and 2 A requirements with slightly improved forward voltage characteristics (920 mV versus 950 mV) and lower reverse leakage current (5 µA versus 10 µA). The operating temperature range is -55°C to 125°C, which is 25°C lower than the original part. This part is suitable for applications not requiring the full 150°C junction temperature capability.

ES2BA R3G (Taiwan Semiconductor Corporation) is electrically identical to the ES2BAHR3G but is also discontinued at DiGi Electronics, limiting its utility for ongoing procurement.

For Current-Limited Applications (Similar Parts with 1 A Rating):

B1100Q-13-F (Diodes Incorporated) is a Schottky diode rated for 100 V and 1 A in DO-214AC (SMA) package with AEC-Q101 automotive qualification. This part is suitable for applications where the circuit current does not exceed 1 A. The Schottky technology provides lower forward voltage (790 mV) compared to the standard fast recovery diode, reducing power dissipation. Operating temperature range is -65°C to 155°C.

CDBA1100-HF (Comchip Technology) is a Schottky diode rated for 100 V and 1 A in DO-214AC (SMA) package. This part offers forward voltage of 810 mV and operates from -50°C to 150°C.

For Full Current Capability with Schottky Technology (Similar Parts with 2 A Rating):

B2100A-13-F (Diodes Incorporated) is a Schottky diode rated for 100 V and 2 A in DO-214AC (SMA) package. This part maintains the same current rating as the original component with lower forward voltage (790 mV) and operates from -65°C to 125°C. The reduced operating temperature range to 125°C may be limiting for some automotive applications.

B2100AF-13 (Diodes Incorporated) is a Schottky diode rated for 100 V and 2 A in DO-221AC (SMAF) package with flat leads. This part operates from -55°C to 150°C, matching the original temperature range, and is suitable for applications where the SMAF package form factor is acceptable.

Frequently Asked Questions (FAQ)

Q: Can ES2BA be used as a direct replacement for ES2BAHR3G?

A: ES2BA is a parametric equivalent meeting the 100 V, 2 A, and DO-214AC (SMA) package requirements. The forward voltage is slightly lower (920 mV versus 950 mV), and reverse leakage is lower (5 µA versus 10 µA). The operating temperature range is -55°C to 125°C, which is 25°C lower than the original. ES2BA is suitable for replacement in applications not requiring operation above 125°C junction temperature.

Q: What is the difference between the ES2BAHR3G and ES2BAH?

A: ES2BAH is electrically and mechanically identical to ES2BAHR3G. Both are rated for 100 V, 2 A, with 950 mV forward voltage, 35 ns recovery time, and operate from -55°C to 150°C in DO-214AC (SMA) packages. The primary difference is product status: ES2BAHR3G is discontinued at DiGi Electronics, while ES2BAH is active in production. ES2BAH is the recommended substitute for ongoing procurement.

Q: Can Schottky diodes (B1100 or B2100 series) replace the ES2BAHR3G?

A: Schottky diodes differ in technology from the standard fast recovery diode. The B1100 series is rated for 1 A (half the current rating of the original), while the B2100 series is rated for 2 A. Schottky diodes exhibit lower forward voltage (790 mV for B2100A-13-F versus 950 mV for ES2BAHR3G) and higher reverse leakage current (10 µA for B2100A-13-F versus 10 µA for ES2BAHR3G). Schottky diodes are suitable for replacement only in applications where the circuit design accommodates the different forward voltage characteristics and where the current requirement does not exceed the Schottky part rating.

Q: What is the significance of the DO-214AC (SMA) package?

A: DO-214AC (SMA) is a surface mount package with specific mechanical and electrical footprint dimensions. All parametric equivalents (ES2BA, ES2BA R3G, ES2BAH) use this identical package, ensuring direct PCB compatibility without layout modifications. Similar parts using alternative packages (DO-214AA SMB, DO-221AC SMAF) require PCB redesign and are not pin-compatible.

Q: Why do some substitute parts have lower operating temperature ranges?

A: Operating temperature range is determined by the semiconductor material and device design. ES2BA operates to 125°C junction temperature, while ES2BAHR3G operates to 150°C. For applications requiring full 150°C capability, ES2BAH or B2100AF-13 are appropriate selections. For applications with lower temperature requirements, ES2BA provides an active production alternative.

Q: Is AEC-Q101 qualification important for substitution?

A: AEC-Q101 qualification indicates the component meets automotive reliability standards. ES2BAHR3G and ES2BAH both carry AEC-Q101 qualification. B1100Q-13-F also carries AEC-Q101 qualification. For automotive applications, selection of AEC-Q101 qualified parts is required. Non-qualified parts may not meet design specifications for automotive use.

Q: What is the difference between ES2BA R3G and ES2BAH?

A: Both parts are manufactured by Taiwan Semiconductor Corporation with identical electrical specifications (100 V, 2 A, 950 mV forward voltage, 35 ns recovery time, -55°C to 150°C). ES2BA R3G is discontinued at DiGi Electronics, while ES2BAH is active in production. For new designs and ongoing procurement, ES2BAH is the appropriate selection.

Q: Can B2100AF-13 replace ES2BAHR3G despite the different package?

A: B2100AF-13 uses DO-221AC (SMAF) package with flat leads, which differs mechanically from the DO-214AC (SMA) package of the original part. Direct PCB substitution is not possible without layout modification. However, B2100AF-13 meets the 100 V, 2 A electrical requirements and operates from -55°C to 150°C, matching the original temperature range. This part is suitable for replacement only when PCB redesign is feasible.
