ES3GC-HF General Purpose Rectifier Diode Equivalent & Substitute Parts

Part Overview

The ES3GC-HF is a general purpose rectifier diode manufactured by Comchip Technology, rated for 400 V DC reverse voltage and 3 A average rectified current in a surface mount DO-214AB (SMC) package. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to component availability, supply chain considerations, or design flexibility within the same functional category.

Substitute Part Grouping Explanation

Substitute parts for the ES3GC-HF are qualified based on the following critical parameters that determine functional equivalence:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 3 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature - Junction: -55°C to 150°C

Mechanical Equivalence Criteria:

• Package / Case: DO-214AB, SMC
• Mounting Type: Surface Mount

Compliance Criteria:

• RoHS Status: ROHS3 Compliant
• Product Status: Active

All substitute parts listed meet these core parameters and are therefore electrically and mechanically interchangeable with the ES3GC-HF in applications requiring a 400 V, 3 A general purpose rectifier diode in surface mount packaging.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are Active product status components with ROHS3 compliance, meeting the same regulatory and environmental requirements as the ES3GC-HF. Selection among these equivalents is based on the following factors:

ER3G_R1_00001 (Panjit International Inc.): This part demonstrates superior reverse leakage current performance at 1 µA @ 400 V compared to the main part specification of 5 µA @ 400 V, with equivalent reverse recovery time of 35 ns. Inventory availability is 5690 pieces.

ES3GC (MDD): This part maintains identical electrical specifications to the ES3GC-HF, including reverse leakage current of 5 µA @ 400 V and reverse recovery time of 35 ns. Inventory availability is 2200 pieces. REACH Unaffected status is documented.

MC03FA40-TE16L (KYOCERA AVX): This part features a faster reverse recovery time of 30 ns compared to the 35 ns specification of the main part, with higher reverse leakage current of 10 µA @ 400 V. Inventory availability is 8245 pieces, the highest among all listed substitutes.

All parts are suitable for direct substitution in applications where the 400 V, 3 A rectifier diode specification is required, with selection determined by availability, inventory levels, and secondary performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can ER3G_R1_00001 be used as a direct replacement for ES3GC-HF?

A: Yes. Both parts meet the core electrical specifications of 400 V reverse voltage, 3 A average rectified current, 1.25 V forward voltage at 3 A, and fast recovery speed classification. Both are housed in DO-214AB (SMC) surface mount packages with identical operating temperature ranges of -55°C to 150°C and ROHS3 compliance.

Q: What is the difference in reverse leakage current between the substitute parts?

A: The ES3GC-HF and ES3GC (MDD) specify 5 µA @ 400 V. The ER3G_R1_00001 (Panjit) specifies 1 µA @ 400 V, representing lower leakage. The MC03FA40-TE16L (KYOCERA AVX) specifies 10 µA @ 400 V, representing higher leakage. All values remain within acceptable ranges for general purpose rectifier applications.

Q: Are there package differences between the substitute parts?

A: All parts use the DO-214AB (SMC) package designation. The MC03FA40-TE16L uses a supplier device package designation of nSMC_FL, which is mechanically and electrically compatible with the standard DO-214AB (SMC) package used by other parts in this list.

Q: What is the difference in reverse recovery time?

A: The ES3GC-HF, ER3G_R1_00001, and ES3GC specify 35 ns reverse recovery time. The MC03FA40-TE16L specifies 30 ns, representing faster recovery performance. All parts meet the fast recovery speed classification of ≤ 500ns for currents > 200mA (Io).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status, meeting the same environmental and regulatory requirements as the ES3GC-HF.

Q: Which substitute part has the highest inventory availability?

A: MC03FA40-TE16L (KYOCERA AVX) has 8245 pieces in stock, followed by ER3G_R1_00001 (Panjit) with 5690 pieces, and ES3GC (MDD) with 2200 pieces.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All substitute parts are surface mount components in the DO-214AB (SMC) package with identical footprints and mounting requirements, allowing direct substitution on PCB assemblies designed for the ES3GC-HF.
