Substitute Part Grouping Explanation

Substitution of the FR201GP-TP is determined by the following critical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 50 V minimum
Current - Average Rectified (Io): 2 A minimum
Voltage - Forward (Vf) (Max) @ If: 1.3 V or lower at rated current
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
Reverse Recovery Time (trr): 150 ns or lower
Mounting Type: Through Hole
Package / Case: DO-204AC or DO-15 (Axial)
Operating Temperature Range: -55°C to 150°C minimum

Parametric Equivalent Parts meet all primary substitution criteria and are direct functional replacements with identical or superior electrical characteristics.

Similar Parts meet the voltage and current requirements but may differ in secondary parameters such as recovery speed classification or reverse leakage characteristics. These parts are suitable for applications where the specific recovery time is not critical.

Engineering Selection Recommendations

Parametric Equivalent Parts (Direct Replacements):

The following parts are parametric equivalents and provide identical electrical performance to the FR201GP-TP:

FR201G (Taiwan Semiconductor Corporation): Active product status. Meets all electrical specifications including 50 V reverse voltage, 2 A average rectified current, 1.3 V forward voltage, and 150 ns reverse recovery time. Lower capacitance (10pF) compared to the main part. ROHS3 compliant.
FR201GT-G (Comchip Technology): Active product status. Meets all electrical specifications including 50 V reverse voltage, 2 A average rectified current, 1.3 V forward voltage, and 150 ns reverse recovery time. Supplied in Tape & Reel packaging. ROHS3 compliant.
PG200R_R2_00001 (Panjit International Inc.): Active product status. Meets all electrical specifications including 50 V reverse voltage, 2 A average rectified current, 1.3 V forward voltage, and 150 ns reverse recovery time. Superior reverse leakage performance (1 µA vs. 5 µA). Supplied in Tape & Reel packaging. ROHS3 compliant.

Similar Parts (Functional Alternatives):

1N5391GHA0G (Taiwan Semiconductor Corporation): Active product status. Meets voltage requirement (50 V) but rated for 1.5 A average rectified current, which is lower than the 2 A specification of the main part. Classified as Standard Recovery (>500ns) rather than Fast Recovery. Forward voltage is 1.1 V @ 1.5 A. Includes AEC-Q101 automotive qualification. ROHS3 compliant. This part is suitable only for applications where the current requirement does not exceed 1.5 A and recovery speed is not critical.

All substitute parts maintain the through-hole mounting type, DO-15 package compatibility, and operating temperature range of the original FR201GP-TP.

Frequently Asked Questions (FAQ)

Q: Can FR201G be used as a direct replacement for FR201GP-TP?

A: Yes. FR201G is a parametric equivalent with identical voltage (50 V), current (2 A), forward voltage (1.3 V @ 2 A), and recovery time (150 ns) specifications. Both are fast recovery diodes in DO-15 packages. FR201G has active product status, making it suitable for new applications requiring this specification.

Q: What is the difference between FR201GT-G and PG200R_R2_00001?

A: Both are parametric equivalents with identical electrical specifications. The primary difference is reverse leakage current: PG200R_R2_00001 specifies 1 µA @ 50 V compared to 5 µA @ 50 V for FR201GT-G. Both are supplied in Tape & Reel packaging. Selection depends on application requirements for leakage performance.

Q: Why is 1N5391GHA0G listed as a similar part rather than a parametric equivalent?

A: The 1N5391GHA0G is rated for 1.5 A average rectified current, which is lower than the 2 A specification of the FR201GP-TP. Additionally, it is classified as Standard Recovery (>500ns) rather than Fast Recovery (≤500ns). These differences make it unsuitable for applications requiring the full 2 A current capacity or fast recovery characteristics. It is suitable only for applications with lower current requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of the FR201GP-TP.

Q: What is the significance of the DO-15 package designation?

A: DO-15 is the industry standard package designation for axial-lead through-hole rectifier diodes. All listed parts use DO-204AC or DO-15 package designations, ensuring mechanical and electrical compatibility in existing PCB layouts designed for the FR201GP-TP.

Q: Can I use these parts interchangeably in my circuit?

A: Parametric equivalent parts (FR201G, FR201GT-G, PG200R_R2_00001) are direct functional replacements and can be used interchangeably with the FR201GP-TP. The similar part (1N5391GHA0G) is suitable only for applications where the current requirement does not exceed 1.5 A and recovery speed is not critical.

Q: What does "Not For New Designs" mean for the FR201GP-TP?

A: This designation indicates that Micro Commercial Co has discontinued active development and promotion of this part number. The part remains available in inventory but is no longer recommended for new circuit designs. Parametric equivalent parts with active product status are recommended for new applications.

Q: How do I determine which substitute part is best for my application?

A: Selection is based on three factors: (1) Current requirement—if your application requires the full 2 A capacity, use parametric equivalents; if 1.5 A is sufficient, 1N5391GHA0G is acceptable. (2) Recovery speed—if fast recovery (≤500ns) is required, use parametric equivalents; if standard recovery is acceptable, 1N5391GHA0G is suitable. (3) Reverse leakage—if low leakage is critical, PG200R_R2_00001 offers superior performance at 1 µA @ 50 V.
