Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical and mechanical compatibility with the ES2BA R3G:

Parametric Equivalents share identical or functionally equivalent electrical specifications and package form factors. These parts satisfy all critical parameters: 100 V reverse voltage rating, 2 A average rectified current, fast recovery characteristics (≤500 ns), DO-214AC (SMA) surface mount package, and ROHS3 compliance. Parametric equivalents differ only in manufacturer, forward voltage characteristics within acceptable ranges, reverse leakage current specifications, or product status (active versus discontinued).

Similar Parts maintain the same reverse voltage rating (100 V) and surface mount package category but differ in one or more critical parameters: reduced current rating (1 A instead of 2 A), alternative technology (Schottky versus standard rectifier), different package variants (SMB, SMAF), or modified operating temperature ranges. Similar parts require design verification to confirm suitability for the intended application.

Key Parameters Determining Substitution:

Voltage - DC Reverse (Vr) (Max): 100 V
Current - Average Rectified (Io): 2 A (parametric equivalents); 1 A (similar parts)
Package / Case: DO-214AC, SMA (parametric equivalents); alternative SMA variants (similar parts)
Technology: Standard (parametric equivalents); Schottky (similar parts)
Speed: Fast Recovery ≤500 ns, >200 mA (Io)
RoHS Status: ROHS3 Compliant

Engineering Selection Recommendations

Parametric Equivalent Selection:

The ES2BAH manufactured by Taiwan Semiconductor Corporation is the primary parametric equivalent to the discontinued ES2BA R3G. Both parts share identical electrical specifications: 100 V reverse voltage, 2 A average rectified current, 950 mV forward voltage at 2 A, 35 ns reverse recovery time, and 10 µA reverse leakage current at 100 V. The ES2BAH maintains the same DO-214AC (SMA) package and operating temperature range (-55°C to 150°C). The ES2BAH is currently active in production and carries AEC-Q101 automotive qualification, providing enhanced reliability documentation. ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating are maintained.

The ES2BA manufactured by Good-Ark Semiconductor provides an alternative parametric equivalent with active product status. This part meets all critical electrical parameters with the exception of forward voltage (920 mV versus 950 mV at 2 A) and reverse leakage current (5 µA versus 10 µA at 100 V), both of which represent improved performance characteristics. The operating temperature range is reduced to -55°C to 125°C. ROHS3 compliance is maintained. This part is supplied in Tape & Reel packaging format.

Similar Part Selection:

The B2100A-13-F and B2100AF-13 manufactured by Diodes Incorporated are Schottky diodes rated for 100 V reverse voltage and 2 A average rectified current, matching the current rating of the ES2BA R3G. Both parts feature lower forward voltage (790 mV at 2 A) compared to the standard rectifier technology of the original part. The B2100A-13-F maintains the DO-214AC (SMA) package, while the B2100AF-13 uses a DO-221AC (SMAF) package with flat leads. Operating temperature ranges are -65°C to 125°C and -55°C to 150°C respectively. Both parts are ROHS3 compliant and carry MSL 1 rating.

The CDBA2100-HF manufactured by Comchip Technology is a Schottky diode with 100 V reverse voltage and 2 A average rectified current in DO-214AC (SMA) package. Forward voltage is 810 mV at 2 A. Operating temperature range is -50°C to 150°C. ROHS3 compliance is maintained.

Schottky Technology Consideration:

Schottky diodes (B2100A-13-F, B2100AF-13, CDBA2100-HF) exhibit lower forward voltage drop and faster switching characteristics compared to standard rectifier technology. These parts are suitable for applications where reduced power dissipation and improved efficiency are required. However, Schottky diodes typically exhibit higher reverse leakage current (500 µA versus 10 µA at 100 V for standard rectifiers), which may impact applications with stringent leakage specifications or high-temperature operation.

Current Rating Consideration:

Parts rated for 1 A average rectified current (B1100-13-F, B1100B-13-F, B1100LB-13-F, B1100Q-13-F, CDBA1100-HF) are not suitable as direct substitutes for the 2 A ES2BA R3G without circuit redesign or thermal management modifications.

Frequently Asked Questions (FAQ)

Q: Can the ES2BAH be used as a direct replacement for the discontinued ES2BA R3G?

A: Yes. The ES2BAH is a parametric equivalent with identical electrical specifications and package form factor. Both parts are rated for 100 V reverse voltage, 2 A average rectified current, 35 ns reverse recovery time, and operate across -55°C to 150°C. The ES2BAH is currently in active production with AEC-Q101 automotive qualification.

Q: What is the difference between the ES2BA (Good-Ark) and ES2BAH (Taiwan Semiconductor) equivalents?

A: Both are parametric equivalents with identical package and core electrical ratings. The ES2BA (Good-Ark) features slightly lower forward voltage (920 mV versus 950 mV at 2 A) and lower reverse leakage current (5 µA versus 10 µA at 100 V), representing improved performance. The ES2BA (Good-Ark) operating temperature range is -55°C to 125°C, compared to -55°C to 150°C for the ES2BAH. The ES2BA (Good-Ark) is supplied in Tape & Reel packaging.

Q: Can Schottky diodes such as B2100A-13-F or CDBA2100-HF replace the ES2BA R3G?

A: Schottky diodes are similar parts with matching 100 V reverse voltage and 2 A current ratings in compatible surface mount packages. Schottky technology provides lower forward voltage (790–810 mV versus 950 mV) and faster switching. However, Schottky diodes exhibit significantly higher reverse leakage current (500 µA versus 10 µA at 100 V). Substitution requires verification that the application tolerates increased leakage current and that thermal management remains adequate.

Q: Why are 1 A rated diodes (B1100 series, CDBA1100-HF) listed as similar parts rather than equivalents?

A: These parts have reduced current rating (1 A versus 2 A average rectified current). Direct substitution without circuit redesign is not appropriate. Applications requiring 2 A operation would exceed the current rating of these parts, resulting in thermal stress and potential failure.

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

A: DO-214AC (SMA) and DO-214AA (SMB) are distinct surface mount packages with different physical dimensions and thermal characteristics. Parts in SMB package (B1100B-13-F, B1100LB-13-F) are not pin-compatible with SMA footprints without PCB redesign. The SMA package is smaller and suitable for space-constrained applications, while SMB provides improved thermal dissipation.

Q: Are all listed substitute parts ROHS3 compliant?

A: Yes. All parametric equivalent and similar parts listed carry ROHS3 compliance certification. All parts maintain MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape (CT) packaging supplies individual components on carrier tape, suitable for small-quantity orders and manual assembly. Tape & Reel (TR) packaging supplies components on continuous reel format, optimized for high-volume automated assembly. Both packaging formats contain identical components; the difference is in supply format and handling method.

Q: Can the B2100AF-13 with SMAF package be used in place of the SMA-packaged ES2BA R3G?

A: The B2100AF-13 uses DO-221AC (SMAF) package with flat leads, which is not pin-compatible with DO-214AC (SMA) footprints. PCB redesign is required for substitution. The B2100AF-13 provides matching 100 V reverse voltage, 2 A current rating, and -55°C to 150°C operating temperature range, making it suitable for applications where package redesign is feasible.

Q: What is AEC-Q101 qualification and why does it matter?

A: AEC-Q101 is an automotive industry qualification standard for discrete semiconductors. The ES2BAH carries this qualification, indicating compliance with automotive reliability and quality requirements. This certification is relevant for applications in automotive, industrial, or other mission-critical environments requiring enhanced reliability documentation.
