ES2M-TP Equivalent & Substitute Parts

Part Overview

The ES2M-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 1000 V DC reverse voltage and 2 A average rectified current in a DO-214AC surface mount package. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design requirements and procurement needs. Substitute parts are selected based on electrical performance parameters, mechanical compatibility, and package specifications that permit direct replacement or functional equivalence in circuit applications.

Substitute Part Grouping Explanation

Substitute parts for the ES2M-TP are classified into two categories based on electrical parameter alignment:

Direct Equivalent (Full Current Rating Match): The US2MA-TP maintains identical voltage ratings (1000 V reverse, 2 A average rectified current) and forward voltage characteristics (1.7 V @ 2 A). This part is a direct functional replacement with improved reverse recovery time (75 ns versus 100 ns) and is currently in active product status with high inventory availability.

Functional Substitutes (Reduced Current Rating): The S1MHE3_A/I and US1M-M3/5AT both operate at 1000 V reverse voltage but are rated for 1 A average rectified current, representing a 50% reduction in current capacity. These parts are suitable for applications where the circuit current requirement does not exceed 1 A. The S1MHE3_A/I includes automotive qualification (AEC-Q100), while the US1M-M3/5AT maintains fast recovery characteristics matching the original part.

Substitution logic is based on the following criteria:

Voltage - DC Reverse (Vr) (Max): Must equal or exceed 1000 V
Package / Case: Must be DO-214AC, SMA (surface mount compatibility)
Operating Temperature Range: Must encompass or exceed -50°C to 150°C
Current Rating: Direct equivalents maintain 2 A; functional substitutes operate at reduced 1 A rating

Engineering Selection Recommendations

For Direct Replacement (Preferred): The US2MA-TP is the recommended direct equivalent for the obsolete ES2M-TP. Both parts maintain identical electrical specifications for voltage rating (1000 V), current capacity (2 A), and forward voltage (1.7 V @ 2 A). The US2MA-TP offers superior reverse recovery time (75 ns versus 100 ns), is currently in active product status, and maintains ROHS3 compliance. Inventory availability is significantly higher (205,564 units) compared to the original part. This part is suitable for all applications previously designed with the ES2M-TP without circuit modification.

For Current-Limited Applications: The S1MHE3_A/I and US1M-M3/5AT are applicable only in circuits where the average rectified current requirement does not exceed 1 A. The S1MHE3_A/I includes automotive-grade qualification (AEC-Q100) and is suitable for automotive applications. The US1M-M3/5AT maintains fast recovery characteristics and is available in cut tape packaging. Both parts are in active product status and ROHS3 compliant.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original ES2M-TP. Operating temperature ranges for substitute parts (-55 to 150°C) encompass or exceed the original specification (-50 to 150°C).

Frequently Asked Questions (FAQ)

Q: Can the US2MA-TP be used as a direct replacement for the ES2M-TP? A: Yes. The US2MA-TP is a direct equivalent with identical voltage (1000 V), current (2 A), and forward voltage (1.7 V @ 2 A) specifications. It is currently in active product status and available in high volume.

Q: What is the primary difference between the US2MA-TP and the S1MHE3_A/I? A: The US2MA-TP maintains the 2 A current rating of the original ES2M-TP, while the S1MHE3_A/I is rated for 1 A. The S1MHE3_A/I includes automotive qualification (AEC-Q100) and operates with standard recovery speed (1.8 µs) rather than fast recovery. Selection depends on circuit current requirements and application environment.

Q: Are the 1 A rated parts (S1MHE3_A/I and US1M-M3/5AT) suitable for all applications? A: No. These parts are suitable only for applications where the average rectified current does not exceed 1 A. Circuits designed for 2 A operation require the US2MA-TP or equivalent 2 A rated device.

Q: What is the difference between the packaging options for substitute parts? A: The US2MA-TP and S1MHE3_A/I are supplied in Tape & Reel (TR) format, suitable for automated assembly. The US1M-M3/5AT is supplied in Cut Tape (CT) format. Both formats are compatible with standard surface mount assembly processes; selection depends on production volume and assembly equipment.

Q: Do all substitute parts meet the same compliance standards as the ES2M-TP? A: Yes. All substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory compliance of the original ES2M-TP.

Q: What is the significance of reverse recovery time differences? A: The US2MA-TP has a reverse recovery time of 75 ns compared to the original 100 ns, representing improved switching performance. The S1MHE3_A/I has a reverse recovery time of 1.8 µs, indicating standard recovery speed suitable for lower-frequency applications. Selection depends on circuit switching frequency requirements.

Q: Can the US1M-M3/5AT be used in place of the US2MA-TP? A: Only if the circuit current requirement does not exceed 1 A. The US1M-M3/5AT is rated for 1 A average rectified current, while the US2MA-TP is rated for 2 A. Using a lower-rated device in a higher-current circuit results in component failure.
