Substitute Part Grouping Explanation

Substitution of the ES2B-13 is determined by strict equivalence in the following electrical and mechanical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 100 V minimum
Current - Average Rectified (Io): 2 A minimum
Package / Case: DO-214AA, SMB (Surface Mount)
Mounting Type: Surface Mount

Secondary Compatibility Factors:

Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io) preferred for functional equivalence
Reverse Recovery Time (trr): ≤ 500 ns acceptable range
Operating Temperature Range: Must encompass or exceed -55°C to 150°C

Parts are grouped into three categories:

Direct Equivalents (ES2B-13-F): Identical electrical specifications and packaging, differing only in product status and compliance certifications.
Functional Equivalents (CGRB202-G, MURS210T3G, S2B): Meet or exceed all primary substitution criteria with minor variations in forward voltage or recovery time characteristics.
Partial Equivalents (MURS110T3G): Meet voltage and package requirements but with reduced current rating (1 A vs. 2 A), suitable only for applications with lower current demands.

Engineering Selection Recommendations

Direct Replacement (Recommended for New Designs):

ES2B-13-F is the primary substitute for ES2B-13. This part is manufactured by Diodes Incorporated and maintains identical electrical specifications including 100 V reverse voltage, 2 A average rectified current, 920 mV forward voltage at 2 A, and 25 ns reverse recovery time. The ES2B-13-F is supplied in Tape & Reel packaging, carries Active product status, and is ROHS3 compliant, addressing the RoHS non-compliance limitation of the original ES2B-13.

Alternative Equivalents (Active Status):

MURS210T3G (onsemi) provides full electrical equivalence with 100 V reverse voltage and 2 A current rating. This part exhibits 940 mV forward voltage at 2 A and 30 ns reverse recovery time, representing minimal deviation from the original specification. MURS210T3G is ROHS3 compliant and carries Last Time Buy status, indicating continued availability with defined end-of-life timeline.

CGRB202-G (Comchip Technology) meets all primary substitution criteria with 100 V reverse voltage and 2 A current rating. Forward voltage is specified at 1.1 V @ 2 A, representing a 180 mV increase relative to ES2B-13. CGRB202-G is ROHS3 compliant and maintains Active product status with substantial inventory availability.

Compliance Considerations:

All recommended substitutes (ES2B-13-F, MURS210T3G, CGRB202-G) are ROHS3 compliant, addressing regulatory requirements not met by the original ES2B-13. All parts maintain REACH Unaffected status and EAR99 export classification.

Partial Equivalents:

MURS110T3G (onsemi) is suitable only for applications where current demand does not exceed 1 A. This part shares the 100 V reverse voltage rating and SMB package but provides half the current capacity of ES2B-13.

S2B (Diotec Semiconductor) meets voltage and current requirements but exhibits Standard Recovery characteristics (>500ns, 1.5 µs trr) versus the Fast Recovery specification of ES2B-13. This part is appropriate only for applications where recovery speed is not a critical parameter.

Frequently Asked Questions (FAQ)

Q: Can ES2B-13-F be used as a direct replacement for ES2B-13?

A: Yes. ES2B-13-F is manufactured by Diodes Incorporated and maintains identical electrical specifications: 100 V reverse voltage, 2 A average rectified current, 920 mV forward voltage at 2 A, and 25 ns reverse recovery time. The primary differences are product status (Active vs. Discontinued) and RoHS compliance (ROHS3 vs. Non-compliant). ES2B-13-F is supplied in Tape & Reel packaging.

Q: What is the difference between fast recovery and standard recovery diodes?

A: Recovery speed is determined by reverse recovery time (trr). Fast recovery diodes exhibit trr ≤ 500 ns, while standard recovery diodes exhibit trr > 500 ns. ES2B-13 specifies 25 ns (fast recovery). S2B specifies 1.5 µs (standard recovery). Fast recovery diodes are required in high-frequency switching applications; standard recovery diodes are suitable for lower-frequency rectification. Application requirements determine which classification is appropriate.

Q: Can MURS110T3G replace ES2B-13?

A: MURS110T3G is not a full equivalent. While it shares the 100 V reverse voltage rating and SMB package, it is rated for 1 A average rectified current versus 2 A for ES2B-13. MURS110T3G is suitable only for applications where current demand does not exceed 1 A. For applications requiring 2 A capacity, MURS210T3G is the appropriate onsemi substitute.

Q: What is the impact of forward voltage differences between substitutes?

A: Forward voltage (Vf) affects power dissipation and voltage drop across the diode during conduction. ES2B-13 specifies 920 mV @ 2 A. CGRB202-G specifies 1.1 V @ 2 A (180 mV higher). S2B specifies 1.15 V @ 2 A (230 mV higher). Higher forward voltage results in increased power dissipation and greater voltage drop. Application thermal and voltage margin requirements determine acceptable Vf variation.

Q: Are all recommended substitutes RoHS compliant?

A: ES2B-13-F, MURS210T3G, CGRB202-G, and MURS110T3G are all ROHS3 compliant. S2B carries "Not applicable" RoHS status. ES2B (YAGEO) is ROHS3 compliant. If RoHS compliance is a design requirement, ES2B-13 (non-compliant) must be replaced with one of the ROHS3-compliant alternatives.

Q: What packaging options are available for substitutes?

A: All recommended substitutes are supplied in Surface Mount SMB (DO-214AA) package, matching ES2B-13. Packaging variations include Tape & Reel (TR) for ES2B-13-F, CGRB202-G, MURS210T3G, and ES2B (YAGEO); Cut Tape (CT) & Digi-Reel for MURS110T3G; and unspecified packaging for S2B. Tape & Reel packaging is standard for high-volume production applications.

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

A: ES2B-13 operates from -55°C to 150°C junction temperature. MURS110T3G and MURS210T3G extend to -65°C to -60°C minimum and 175°C maximum, providing wider temperature margin. CGRB202-G specifies 150°C maximum without minimum specification. S2B operates from -50°C to 150°C. Application temperature requirements determine whether extended range is necessary.

Q: Is ES2B (YAGEO) a suitable substitute?

A: ES2B (YAGEO) shares the base product designation and DO-214AA package. However, complete electrical specifications are not provided in the available data. The part is ROHS3 compliant and maintains Active product status with substantial inventory. Verification of electrical parameters against application requirements is necessary before selection.

Q: What is the significance of "Last Time Buy" status for MURS210T3G?

A: Last Time Buy status indicates that onsemi has announced end-of-life for MURS210T3G with a defined final order date. While the part remains available, procurement quantities should account for future unavailability. For new designs with extended production timelines, ES2B-13-F or CGRB202-G (both Active status) are preferred to ensure long-term supply continuity.
