Engineering Selection Recommendations

Vishay ES2B-E3/5BT: This part is electrically identical to the main part ES2B-M3/5BT with the same packaging format (Tape & Reel). Both parts are in active production status with ROHS3 compliance and unlimited MSL rating. Selection between these two Vishay variants is determined by inventory availability and supplier preference, as electrical and mechanical specifications are equivalent.

Vishay ES2B-E3/52T: This substitute provides identical electrical specifications but is supplied in Cut Tape (CT) format rather than Tape & Reel. This packaging difference affects handling and assembly processes. The part is in active production with ROHS3 compliance and unlimited MSL rating. Selection is appropriate when Cut Tape format is compatible with assembly equipment and processes.

Vishay ES2BHE3_A/H and ES2BHE3_A/I: These automotive-qualified variants (AEC-Q101) feature improved reverse recovery time of 20 ns compared to 30 ns in the main part. Both are in active production status with ROHS3 compliance and unlimited MSL rating. These parts are suitable for applications requiring automotive-grade qualification. The ES2BHE3_A/I variant is preferred over ES2BHE3_A/H based on higher inventory availability (7501 Pcs vs. 3350 Pcs).

Comchip CGRB202-G: This cross-manufacturer substitute meets all core electrical requirements with 100 V reverse voltage, 2 A current rating, and fast recovery operation in identical DO-214AA package. The forward voltage specification of 1.1 V @ 2 A is higher than the 900 mV specification of Vishay parts. This part is in active production status with ROHS3 compliance and unlimited MSL rating. Selection is appropriate when cross-manufacturer sourcing is required or when the higher forward voltage specification is acceptable for the application.

YAGEO ES2B: This alternative source part provides base electrical equivalence with limited parameter documentation. Selection of this part requires confirmation of complete electrical specifications against application requirements.

Frequently Asked Questions (FAQ)

Q: Can ES2B-E3/52T be used as a direct replacement for ES2B-M3/5BT?

A: Yes, ES2B-E3/52T is electrically equivalent to ES2B-M3/5BT. The primary difference is packaging format: ES2B-E3/52T is supplied in Cut Tape (CT) format while ES2B-M3/5BT is supplied in Tape & Reel (TR) format. Both parts have identical electrical specifications, operating temperature range, and compliance ratings. Compatibility depends on whether your assembly equipment can process Cut Tape format.

Q: What is the difference between standard ES2B parts and the ES2BHE3_A automotive variants?

A: The ES2BHE3_A variants include AEC-Q101 automotive qualification and feature improved reverse recovery time of 20 ns compared to 30 ns in standard ES2B parts. Both meet the same 100 V / 2 A electrical specifications and DO-214AA package requirements. Selection of automotive variants is necessary only when AEC-Q101 qualification is a design or procurement requirement.

Q: Is the Comchip CGRB202-G compatible with applications designed for the Vishay ES2B-M3/5BT?

A: CGRB202-G is mechanically and functionally compatible with ES2B-M3/5BT in the same DO-214AA package and mounting configuration. The forward voltage specification differs: CGRB202-G is rated at 1.1 V @ 2 A versus 900 mV @ 2 A for Vishay parts. This higher forward voltage may affect circuit performance in applications with tight voltage margin requirements. Reverse leakage is specified at 5 µA @ 100 V for CGRB202-G versus 10 µA @ 100 V for Vishay parts, representing improved leakage performance.

Q: What packaging formats are available for these substitute parts?

A: ES2B-M3/5BT and ES2B-E3/5BT are supplied in Tape & Reel (TR) format. ES2B-E3/52T is supplied in Cut Tape (CT) format. All other substitutes (ES2BHE3_A/H, ES2BHE3_A/I, CGRB202-G, and YAGEO ES2B) are supplied in Tape & Reel format. Packaging format selection depends on assembly equipment compatibility and procurement volume requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all identified substitute parts including ES2B-E3/52T, ES2B-E3/5BT, ES2BHE3_A/H, ES2BHE3_A/I, CGRB202-G, and YAGEO ES2B are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1) rating.

Q: Which substitute part has the best availability?

A: CGRB202-G from Comchip Technology has the highest inventory availability at 16,075 Pcs. Among Vishay parts, YAGEO ES2B has the highest availability at 55,400 Pcs, though parameter documentation is limited. ES2B-E3/5BT has 8,154 Pcs available and provides complete electrical specification documentation.

Q: Can I use YAGEO ES2B as a substitute?

A: YAGEO ES2B provides base electrical equivalence with 100 V reverse voltage and 0.95 V forward voltage rating. However, the provided data set contains limited parameter documentation for this part. Complete electrical specifications including reverse recovery time, reverse leakage current, and capacitance should be confirmed against application requirements before selection.
