Substitute Part Grouping Explanation

Substitution of the ES3CHR7G is determined by strict equivalence of the following electrical and mechanical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 150 V
Current - Average Rectified (Io): 3 A
Package / Case: DO-214AB (SMC) or compatible surface mount package
Operating Temperature - Junction: -55°C to 150°C minimum
Technology: Standard rectifier diode

Secondary Compatibility Factors:

Reverse Recovery Time (trr): 35 ns or faster
Voltage - Forward (Vf) (Max) @ If: 950 mV or lower at 3 A
Current - Reverse Leakage @ Vr: 10 µA or lower at 150 V
Capacitance @ Vr, F: 45 pF at 4V, 1MHz

Substitute parts are classified into two categories:

Parametric Equivalents: Parts with identical electrical specifications and the same package type (DO-214AB, SMC).

Similar Parts: Parts with identical voltage and current ratings but different package configurations (SMB vs. SMC) or minor variations in secondary parameters (forward voltage, reverse recovery time, reverse leakage current).

Engineering Selection Recommendations

Parametric Equivalents (Direct Substitution):

The ES3C and ES3CH from Taiwan Semiconductor Corporation are parametric equivalents to the ES3CHR7G, offering identical electrical specifications and the same DO-214AB (SMC) package. Both parts are currently in active production status with substantial inventory availability. The ES3CH maintains AEC-Q101 automotive qualification matching the original part. Selection between ES3C and ES3CH depends on automotive qualification requirements; ES3CH is specified for automotive applications, while ES3C is suitable for general-purpose applications.

The ER3C_R1_00001 from Panjit International Inc. is a parametric equivalent with identical voltage, current, and package specifications. This part exhibits superior reverse leakage current performance (1 µA versus 10 µA at 150 V), which may provide operational advantages in low-leakage applications. The part is in active production with adequate inventory.

Similar Parts (Package or Performance Variation):

The ES3C-13-F from Diodes Incorporated maintains the DO-214AB (SMC) package and identical voltage/current ratings. This part demonstrates improved performance characteristics with lower forward voltage (900 mV versus 950 mV at 3 A) and faster reverse recovery time (25 ns versus 35 ns). These improvements reduce power dissipation and switching losses. The part is supplied in Tape & Reel packaging and is in active production.

The ES3CB-13-F from Diodes Incorporated is functionally equivalent but uses the DO-214AA (SMB) package instead of DO-214AB (SMC). This part is suitable only for applications where SMB package footprints are acceptable. It shares the performance improvements of the ES3C-13-F variant (900 mV forward voltage, 25 ns recovery time) and is in active production with high inventory levels.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and REACH unaffected status, matching the original ES3CHR7G specifications. Automotive-grade applications requiring AEC-Q101 qualification should specify ES3CH or verify qualification status with the component supplier.

Frequently Asked Questions (FAQ)

Q: Can ES3C be used as a direct replacement for ES3CHR7G?

A: Yes. The ES3C is a parametric equivalent with identical electrical specifications (150 V, 3 A, 950 mV forward voltage, 35 ns recovery time) and the same DO-214AB (SMC) package. The primary difference is product status: ES3C is active production while ES3CHR7G is discontinued. For non-automotive applications, ES3C provides direct substitution.

Q: What is the difference between ES3CH and ES3C?

A: Both parts are parametric equivalents with identical electrical specifications. The ES3CH carries AEC-Q101 automotive qualification, while ES3C does not. Select ES3CH for automotive-grade applications requiring formal qualification documentation.

Q: Why would I choose ER3C_R1_00001 over ES3C?

A: The ER3C_R1_00001 offers superior reverse leakage current performance (1 µA versus 10 µA at 150 V). This characteristic is beneficial in applications sensitive to leakage current, such as precision analog circuits or low-power standby modes. All other electrical parameters remain equivalent.

Q: Can ES3C-13-F replace ES3CHR7G?

A: Yes, with performance improvements. The ES3C-13-F maintains the same voltage and current ratings and uses the same DO-214AB (SMC) package. It offers lower forward voltage (900 mV versus 950 mV) and faster reverse recovery time (25 ns versus 35 ns), resulting in reduced power dissipation and improved switching performance. The part is supplied in Tape & Reel packaging.

Q: What is the difference between ES3C-13-F and ES3CB-13-F?

A: Both parts are from Diodes Incorporated with identical electrical specifications. The primary difference is the package: ES3C-13-F uses DO-214AB (SMC), while ES3CB-13-F uses DO-214AA (SMB). SMC and SMB packages have different footprints and land patterns. Select based on your PCB design requirements. ES3CB-13-F is suitable only if your design accommodates SMB package dimensions.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance status, matching the original ES3CHR7G specification.

Q: Which substitute part has the best availability?

A: ES3C-13-F and ES3CB-13-F from Diodes Incorporated show the highest inventory levels (10,300 and 10,400 units respectively). ES3C from Taiwan Semiconductor Corporation also maintains substantial inventory (10,200 units).

Q: Can I use ES3CB-13-F in a design that currently uses ES3CHR7G?

A: Only if your PCB design accommodates the SMB package footprint. The ES3CB-13-F uses DO-214AA (SMB) package, which has different dimensions and land pattern compared to the DO-214AB (SMC) package of the original part. Verify PCB compatibility before substitution.

Q: What is the operating temperature range for all substitute parts?

A: All substitute parts maintain the same operating temperature range as the original ES3CHR7G: -55°C to 150°C junction temperature.
