Substitute Part Grouping Explanation

Substitution of the SF2003PTHC0G is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 150 V
• Current - Average Rectified (Io): 20 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 20 A
• Reverse Recovery Time (trr): 35 ns
• Current - Reverse Leakage @ Vr: 10 µA @ 150 V
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical & Environmental Parameters (Must Match):

• Package / Case: TO-247-3
• Mounting Type: Through Hole
• Operating Temperature - Junction: -55°C to 150°C

Compliance & Qualification (Must Match):

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

Substitute parts are grouped into two categories: direct manufacturer equivalents (same base product number, identical electrical and mechanical specifications) and parametric equivalents (matching all critical electrical and mechanical parameters with identical compliance certifications).

Parameter Comparison

Engineering Selection Recommendations

SF2003PTH (Direct Substitute): This part is a direct manufacturer equivalent from Taiwan Semiconductor Corporation with active product status. It maintains identical electrical specifications (150 V, 20 A, 1.1 V forward voltage, 35 ns recovery time) and mechanical compatibility (TO-247-3 through-hole package). The primary distinction is diode configuration: SF2003PTH is specified as a 1 Pair Common Cathode diode array, whereas SF2003PTHC0G is a general-purpose single diode. Both parts carry automotive-grade classification with AEC-Q101 qualification and ROHS3 compliance. Selection of SF2003PTH is appropriate when the application circuit topology accommodates the common cathode configuration.

SF2003PT C0G (Parametric Equivalent): This part is a parametric equivalent with active product status, matching all critical electrical and mechanical parameters of the main part. It shares identical voltage ratings (150 V), current capacity (20 A), forward voltage characteristics (1.1 V @ 20 A), and recovery time (35 ns). The part maintains the same TO-247-3 through-hole package, automotive-grade specification, AEC-Q101 qualification, and ROHS3 compliance. SF2003PT C0G is functionally interchangeable with SF2003PTHC0G for general-purpose rectification applications within the specified electrical and thermal operating ranges.

Both substitute parts are manufactured by the same supplier, ensuring consistency in quality standards and supply chain reliability. Selection between substitutes should be based on circuit configuration requirements and application-specific topology considerations.

Frequently Asked Questions (FAQ)

Q: Can SF2003PTH be used as a direct replacement for SF2003PTHC0G?

A: SF2003PTH is electrically and mechanically equivalent to SF2003PTHC0G across all critical parameters (150 V reverse voltage, 20 A current, 1.1 V forward voltage, 35 ns recovery time, TO-247-3 package). However, SF2003PTH is configured as a 1 Pair Common Cathode diode array, while SF2003PTHC0G is a general-purpose single diode. Substitution is valid only if the application circuit topology accommodates the common cathode configuration.

Q: What is the difference between SF2003PT C0G and SF2003PTHC0G?

A: Both parts are parametrically identical in electrical specifications (150 V, 20 A, 1.1 V forward voltage, 35 ns recovery time) and mechanical packaging (TO-247-3 through-hole). Both maintain automotive-grade classification, AEC-Q101 qualification, and ROHS3 compliance. SF2003PT C0G has active product status, whereas SF2003PTHC0G is discontinued at DiGi Electronics. SF2003PT C0G is a direct functional substitute for new designs and ongoing procurement.

Q: Are all substitute parts automotive-qualified?

A: Yes. Both SF2003PTH and SF2003PT C0G carry automotive-grade classification with AEC-Q101 qualification, matching the main part SF2003PTHC0G. All three parts are suitable for automotive applications requiring this qualification level.

Q: Do the substitute parts have the same package footprint?

A: Yes. All parts use the TO-247-3 through-hole package (TO-247AD / TO-3P supplier designation). PCB layout and mounting hole patterns are identical, enabling direct mechanical substitution without circuit board redesign.

Q: What is the operating temperature range for these parts?

A: All three parts (SF2003PTHC0G, SF2003PTH, and SF2003PT C0G) operate across a junction temperature range of -55°C to 150°C, providing identical thermal performance specifications.

Q: Are these parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the reverse recovery time specification?

A: All three parts specify a reverse recovery time (trr) of 35 nanoseconds with fast recovery classification (≤ 500ns, > 200mA). This parameter is critical for high-frequency switching applications and rectification circuits requiring rapid diode turn-off characteristics.
