Engineering Selection Recommendations

Primary Substitutes (Identical Reverse Recovery Time):

FR204GT-G (Comchip Technology) and PG204R_R2_00001 (Panjit International Inc.) maintain the same 150 ns reverse recovery time as the FR204GP-TP, providing direct functional equivalence. Both are Active status products with ROHS3 compliance and MSL 1 rating. FR204GT-G is available in Tape & Reel packaging, while PG204R_R2_00001 offers improved reverse leakage characteristics at 1 µA versus 5 µA.

FR204G (Taiwan Semiconductor Corporation) also matches the 150 ns reverse recovery time and is Active status. This part is supplied in Cut Tape format with the lowest capacitance specification at 10 pF.

Frequently Asked Questions (FAQ)

Q: Can FR204GT-G directly replace FR204GP-TP in existing circuit boards?

A: Yes. FR204GT-G maintains identical electrical specifications: 400 V reverse voltage, 2 A average rectified current, 1.3 V forward voltage at 2 A, and 150 ns reverse recovery time. Both use DO-15 through-hole packages with identical pin configurations and mounting requirements. The primary difference is packaging format (Tape & Reel versus original Tape & Reel) and manufacturer (Comchip Technology versus Micro Commercial Co).

Q: What is the difference between SF26G and SF2L6G?

A: Both parts share identical electrical ratings and 35 ns reverse recovery time. The primary distinction is reverse leakage current: SF26G specifies 5 µA @ 400 V, while SF2L6G specifies 1 µA @ 400 V. SF2L6G provides superior leakage performance. Both are supplied in Cut Tape format by Taiwan Semiconductor Corporation.

Q: Are SF26GH and SF2L6GH suitable for automotive applications?

A: Yes. Both SF26GH and SF2L6GH carry Automotive grade designation with AEC-Q101 qualification. They maintain the same 400 V / 2 A ratings and 35 ns reverse recovery time as standard versions. SF2L6GH offers the additional benefit of 1 µA reverse leakage versus 5 µA in SF26GH.

Q: What does "Not For New Designs" status mean for FR204GP-TP?

A: This designation indicates the part has reached end-of-life and is no longer recommended for new circuit designs. However, it remains available for existing applications and maintenance. All listed substitute parts carry Active status, confirming ongoing manufacturing support and availability for new designs.

Q: Can I use Cut Tape (CT) packaged parts as replacements for Tape & Reel (TR) packaged FR204GP-TP?

A: Cut Tape and Tape & Reel formats contain identical components with different packaging presentations. The electrical and mechanical specifications are equivalent. Substitution is valid from a component perspective; however, procurement and assembly processes may require adjustment to accommodate different packaging formats.

Q: What is the significance of reverse recovery time differences between 35 ns and 150 ns?

A: Reverse recovery time (trr) determines switching speed during diode turn-off. Lower trr values (35 ns in SF26G, SF26GH, SF2L6G, SF2L6GH) indicate faster switching transitions, reducing switching losses and enabling higher frequency operation. Higher trr values (150 ns in FR204GP-TP, FR204G, FR204GT-G, PG204R_R2_00001) are suitable for lower frequency applications. Selection depends on circuit operating frequency requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the FR204GP-TP specifications. This ensures environmental and regulatory compatibility across all substitutes.

Q: What is the difference between HER205G-TP and HER205G?

A: Both parts are manufactured by different entities (Micro Commercial Co versus Taiwan Semiconductor Corporation) and supplied in different packaging formats (Tape & Reel versus Cut Tape). Electrically, they are equivalent with 50 ns reverse recovery time, 400 V rating, and 2 A current. HER205G-TP is available in Tape & Reel; HER205G is supplied in Cut Tape.

Q: Can I substitute a part with lower reverse leakage (1 µA) for one with higher reverse leakage (5 µA)?

A: Yes. Lower reverse leakage represents improved performance and is a valid substitution. Parts with 1 µA leakage (PG204R_R2_00001, SF2L6G, SF2L6GH) can replace parts with 5 µA leakage (FR204GP-TP, HER205G-TP, FR204G, HER205G, SF26G, SF26G A0G, SF26GH) without circuit modification.
