CGRC502-G Equivalent & Substitute Parts Reference

Part Overview

The CGRC502-G is a general-purpose rectifier diode manufactured by Comchip Technology, rated for 100 V DC reverse voltage and 5 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 inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CGRC502-G are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 100 V minimum
• Package / Case: DO-214AB or SMC equivalent
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Current Rating Consideration: The CGRC502-G is rated for 5 A average rectified current. Substitute parts are grouped into two categories:

1. Direct Equivalent (5 A Rating): S5BC-13-F matches the 5 A current specification, forward voltage, reverse leakage, and recovery speed characteristics.

2. Reduced Current Rating (3 A Rating): S3B-13-F operates at 3 A average rectified current, which represents a lower current capacity than the original part. This substitute is suitable only for applications where the circuit current demand does not exceed 3 A.

All substitute parts maintain identical reverse voltage (100 V), forward voltage (1.15 V @ rated current), reverse leakage (10 µA @ 100 V), and recovery speed specifications.

Parameter Comparison

Engineering Selection Recommendations

S5BC-13-F (Diodes Incorporated): This part is the direct electrical and mechanical equivalent to the CGRC502-G. Both components share identical voltage ratings (100 V), current capacity (5 A), forward voltage characteristics (1.15 V @ 5 A), reverse leakage (10 µA @ 100 V), and recovery speed specifications. The S5BC-13-F is ROHS3 compliant, REACH unaffected, and carries MSL 1 classification. The operating temperature range of -65°C to 150°C encompasses the CGRC502-G maximum junction temperature of 150°C. This substitute is suitable for direct replacement in all applications where the CGRC502-G is specified.

S3B-13-F (Diodes Incorporated): This part shares the same voltage rating (100 V), forward voltage (1.15 V), reverse leakage (10 µA @ 100 V), and recovery speed characteristics as the CGRC502-G. However, the current rating is reduced to 3 A, compared to the 5 A specification of the original part. The S3B-13-F is ROHS3 compliant, REACH unaffected, and carries MSL 1 classification with an operating temperature range of -65°C to 150°C. This substitute is applicable only in circuits where the maximum average rectified current does not exceed 3 A.

Both substitute parts are Active product status and maintain full regulatory compliance with the original component.

Frequently Asked Questions (FAQ)

Q: Can S5BC-13-F replace CGRC502-G in all applications? A: Yes. The S5BC-13-F is electrically and mechanically equivalent to the CGRC502-G. Both components are rated for 100 V reverse voltage, 5 A average rectified current, 1.15 V forward voltage, and identical reverse leakage and recovery speed characteristics. Both are housed in DO-214AB (SMC) Surface Mount packages and are ROHS3 compliant with MSL 1 classification.

Q: When is S3B-13-F appropriate as a substitute? A: The S3B-13-F is appropriate only when the circuit application requires a maximum average rectified current of 3 A or less. The S3B-13-F maintains all other electrical characteristics identical to the CGRC502-G (100 V reverse voltage, 1.15 V forward voltage, 10 µA reverse leakage, standard recovery speed). If the circuit requires 5 A capacity, the S3B-13-F is not suitable.

Q: Are there package compatibility differences between these parts? A: All three parts use the DO-214AB (SMC) Surface Mount package. The CGRC502-G is supplied in Tape & Reel (TR) packaging, while both Diodes Incorporated substitutes are supplied in Cut Tape (CT) & Digi-Reel® packaging. The component footprint and mounting requirements are identical across all three parts.

Q: Do the substitute parts meet the same compliance standards? A: Yes. All three parts are ROHS3 compliant, REACH unaffected, classified as EAR99 for export control, and carry MSL 1 (Unlimited) moisture sensitivity rating. All parts are Active product status.

Q: What is the temperature operating range difference? A: The CGRC502-G specifies a maximum junction temperature of 150°C. The S5BC-13-F and S3B-13-F both specify an operating temperature range of -65°C to 150°C, which includes the maximum temperature of the original part. The substitute parts provide extended low-temperature capability.

Q: How do forward voltage characteristics compare? A: The CGRC502-G and S5BC-13-F both specify 1.15 V maximum forward voltage at 5 A. The S3B-13-F specifies 1.15 V maximum forward voltage at 3 A. Forward voltage characteristics are identical across all three parts at their respective rated currents.

Q: Are reverse leakage specifications identical? A: Yes. All three parts specify 10 µA maximum reverse leakage current at 100 V reverse voltage.
