Substitute Part Grouping Explanation
Substitute parts for the ES1DHM3_A/H are grouped based on strict electrical and mechanical parameter equivalence. The primary substitution criteria are:
Critical Parameters for Substitution:
- Voltage - DC Reverse (Vr) (Max): 200 V
- Current - Average Rectified (Io): 1 A
- Voltage - Forward (Vf) (Max) @ If: 920 mV @ 1 A (or equivalent within specified tolerance)
- Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
- Reverse Recovery Time (trr): 25 ns (or equivalent)
- Current - Reverse Leakage @ Vr: 5 µA @ 200 V
- Package / Case: DO-214AC, SMA
- Operating Temperature - Junction: -55°C to 150°C
- RoHS Status: ROHS3 Compliant
- Moisture Sensitivity Level (MSL): 1 (Unlimited)
Parts are classified as parametric equivalents when all critical electrical parameters match the main part specification. Packaging variants (Tape & Reel, Cut Tape, Digi-Reel) do not disqualify substitution when the supplier device package remains DO-214AC (SMA). Minor variations in reverse recovery time (24 ns vs. 25 ns) and capacitance values remain within acceptable substitution tolerance for general-purpose rectifier applications.

Engineering Selection Recommendations
Vishay ES1D Series (Automotive-Grade): The ES1DHE3_A/H and ES1DHE3_A/I parts carry automotive-grade qualification under AEC-Q101 standard, matching the qualification level of the main part ES1DHM3_A/H. These parts are direct substitutes for applications requiring automotive compliance. ES1D-E3/5AT, ES1D-E3/61T, and ES1D-M3/61T provide equivalent electrical performance without automotive qualification; selection depends on application requirements.
Vishay U1D Series: The U1D-E3/5AT, U1D-E3/61T, and U1D-M3/5AT parts demonstrate equivalent electrical performance with reverse recovery time of 24 ns (compared to 25 ns for the main part). These parts are suitable for applications where the 1 ns difference in trr does not impact circuit performance. All U1D variants maintain ROHS3 compliance and MSL 1 rating.
Alternative Manufacturers: EVVO Semi ES1D and Diodes Incorporated ES1D-13-F provide parametric equivalence in voltage, current, and package specifications. The EVVO Semi ES1D exhibits higher forward voltage (1000 mV vs. 920 mV) and longer reverse recovery time (35 ns vs. 25 ns). The Diodes Incorporated ES1D-13-F maintains 920 mV forward voltage and 25 ns reverse recovery time, providing direct electrical equivalence. Selection of alternative manufacturers depends on supply chain strategy and application tolerance for performance variation.
Packaging Considerations: All substitute parts maintain DO-214AC (SMA) package compatibility. Packaging format variations (Tape & Reel, Cut Tape, Digi-Reel) do not affect electrical performance or mechanical fit. Selection among packaging formats is driven by assembly process requirements and inventory management.
Frequently Asked Questions (FAQ)
Q: Can ES1D-E3/61T be used as a direct replacement for ES1DHM3_A/H?
A: Yes. The ES1D-E3/61T maintains identical electrical specifications: 200 V reverse voltage, 1 A average rectified current, 920 mV forward voltage at 1 A, 25 ns reverse recovery time, and 5 µA reverse leakage current at 200 V. Both parts are ROHS3 compliant with MSL 1 rating and operate across -55°C to 150°C. The primary difference is packaging format (Cut Tape & Digi-Reel vs. Tape & Reel), which does not affect electrical performance or mechanical compatibility in DO-214AC (SMA) package.
Q: What is the difference between ES1DHM3_A/H and ES1DHE3_A/H?
A: Both parts are manufactured by Vishay and share identical electrical specifications. The ES1DHE3_A/H is explicitly qualified to AEC-Q101 automotive standard, while the ES1DHM3_A/H carries automotive-grade designation. Both operate at 200 V, 1 A with 920 mV forward voltage and 25 ns reverse recovery time. Selection between these parts depends on whether explicit AEC-Q101 qualification documentation is required for the application.
Q: Can U1D-E3/5AT replace ES1DHM3_A/H in all applications?
A: The U1D-E3/5AT is electrically equivalent in voltage (200 V), current (1 A), and forward voltage (920 mV @ 1 A). The reverse recovery time is 24 ns compared to 25 ns for the main part. This 1 ns difference is within typical circuit tolerance for general-purpose rectifier applications. Both parts maintain ROHS3 compliance and MSL 1 rating. Substitution is valid unless the application circuit specifically requires the 25 ns trr specification.
Q: Why does EVVO Semi ES1D show 1000 mV forward voltage instead of 920 mV?
A: The EVVO Semi ES1D exhibits higher forward voltage (1000 mV vs. 920 mV at 1 A) and longer reverse recovery time (35 ns vs. 25 ns). These differences indicate different semiconductor process technology. While the part maintains 200 V reverse voltage and 1 A current rating, the higher forward voltage will result in increased power dissipation and heat generation. This part is suitable for applications where forward voltage variation is acceptable; it is not recommended as a direct replacement in circuits optimized for 920 mV forward voltage.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All substitute parts listed in this reference maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level. All parts are suitable for lead-free assembly processes and meet environmental compliance requirements equivalent to the main part ES1DHM3_A/H.
Q: What is the difference between Cut Tape (CT) & Digi-Reel and Tape & Reel (TR) packaging?
A: Cut Tape and Digi-Reel are alternative packaging formats for component delivery, typically used for lower-volume orders or mixed-component kits. Tape & Reel packaging is standard for high-volume production assembly. Both formats contain the same DO-214AC (SMA) package diode with identical electrical specifications. Selection between packaging formats is determined by assembly process requirements and order quantity, not by electrical performance.
Q: Can Diodes Incorporated ES1D-13-F be used in automotive applications?
A: The Diodes Incorporated ES1D-13-F maintains electrical equivalence to the main part (200 V, 1 A, 920 mV forward voltage, 25 ns reverse recovery time) and is ROHS3 compliant. However, the provided data does not indicate AEC-Q101 automotive qualification for this part. If the application requires explicit automotive-grade qualification, verification of the Diodes Incorporated part's qualification status is necessary before substitution in automotive circuits.
Q: What inventory levels should influence part selection?
A: Inventory levels provided in this reference reflect current stock availability and may change. ES1D-E3/61T (2,328,659 pcs), ES1D-13-F (550,400 pcs), and ES1D (140,400 pcs) demonstrate high availability. Parts with lower inventory (ES1DHM3_A/H at 1,078 pcs, ES1D-M3/61T at 3,200 pcs) may present supply constraints for large-volume orders. Inventory status should be verified with suppliers for production planning purposes.
