Substitute Part Grouping Explanation

Substitute parts for the SFF1002G C0G are classified based on the following criteria:

Direct Equivalent: Parts that maintain identical electrical specifications, diode configuration, and package type. These parts are interchangeable without circuit modification.

Parametric Equivalent - Configuration Variant: Parts that maintain all electrical specifications and package type but differ in diode configuration (Common Anode versus Common Cathode). These parts require circuit topology evaluation before substitution.

Parametric Equivalent - Grade Variant: Parts that maintain all electrical specifications and package type but include automotive-grade qualification and AEC-Q101 certification. These parts are suitable for applications requiring automotive compliance.

The key parameters determining substitution eligibility are:

Voltage - DC Reverse (Vr) (Max): 100 V
Current - Average Rectified (Io) (per Diode): 10 A (DC)
Voltage - Forward (Vf) (Max) @ If: 975 mV @ 5 A
Reverse Recovery Time (trr): 35 ns
Package / Case: TO-220-3 Full Pack, Isolated Tab
Mounting Type: Through Hole

Engineering Selection Recommendations

SFF1002G (Direct Equivalent): This part is the primary substitute for the discontinued SFF1002G C0G. It maintains identical electrical specifications and diode configuration while carrying Active product status. This part is suitable for direct replacement in existing designs without circuit modification.

SFF1002GA C0G (Parametric Equivalent - Configuration Variant): This part maintains all electrical specifications and package type but features a Common Anode configuration instead of Common Cathode. Selection of this part requires circuit topology evaluation to confirm compatibility with the existing design. This part is suitable only for applications where the Common Anode configuration is functionally equivalent to the Common Cathode requirement.

SFF1002GHC0G (Parametric Equivalent - Grade Variant): This part maintains identical electrical specifications and diode configuration as the main part while including automotive-grade qualification and AEC-Q101 certification. This part is suitable for applications requiring automotive compliance or operating in automotive environments. The automotive qualification does not affect electrical performance in standard industrial applications.

Frequently Asked Questions (FAQ)

Q: Can SFF1002G be used as a direct replacement for SFF1002G C0G?

A: Yes. The SFF1002G maintains identical electrical specifications, diode configuration (1 Pair Common Cathode), and package type (TO-220-3 Full Pack, Isolated Tab). The part carries Active product status and is available in inventory. No circuit modification is required.

Q: What is the difference between Common Cathode and Common Anode configurations?

A: Common Cathode configuration connects the cathode terminals of both diodes to a single pin, while Common Anode configuration connects the anode terminals to a single pin. These configurations determine the circuit topology and pin connections. The SFF1002GA C0G uses Common Anode configuration and requires circuit topology evaluation before substitution.

Q: Is the SFF1002GHC0G suitable for non-automotive applications?

A: Yes. The SFF1002GHC0G maintains identical electrical specifications as the standard-grade parts. The automotive-grade qualification and AEC-Q101 certification indicate additional quality and reliability testing but do not restrict use in non-automotive applications. This part is suitable for any application requiring the specified electrical parameters.

Q: Are all substitute parts packaged in TO-220-3 Full Pack with isolated tab?

A: Yes. All substitute parts listed maintain the TO-220-3 Full Pack with isolated tab package configuration. This ensures mechanical compatibility with existing through-hole mounting designs.

Q: What is the inventory status for substitute parts?

A: SFF1002G carries 647 pieces in stock, SFF1002GA C0G carries 672 pieces in stock, and SFF1002GHC0G carries 693 pieces in stock. All substitute parts are available for immediate procurement.

Q: Do all parts maintain the same electrical performance specifications?

A: Yes. All substitute parts maintain identical voltage ratings (100 V DC reverse), current ratings (10 A per diode), forward voltage characteristics (975 mV @ 5 A), and reverse recovery time (35 ns). Electrical performance is equivalent across all listed parts.
