Substitute Part Grouping Explanation

Substitute parts for the FR302G A0G are grouped based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

Voltage - DC Reverse (Vr) (Max): 100 V
Current - Average Rectified (Io): 3 A
Package / Case: DO-201AD, Axial
Mounting Type: Through Hole
RoHS3 Compliance

Secondary Compatibility Factors:

Voltage - Forward (Vf) (Max) @ If: 1.2 V to 1.3 V @ 3 A
Current - Reverse Leakage @ Vr: 5 µA @ 100 V
Operating Temperature Range: Minimum -50°C to -55°C; Maximum 150°C or higher

Parts meeting all primary criteria are classified as direct substitutes. The 60S1-TP variant exceeds the current rating (6 A versus 3 A) and is therefore suitable for applications requiring higher current capacity within the same voltage class, though it carries a "Not For New Designs" status.

Engineering Selection Recommendations

Direct Substitutes (Preferred for New Designs):

The 1N5401-E3/54 and 1N5401-E3/73 are functionally equivalent to the FR302G A0G. Both parts are manufactured by Vishay General Semiconductor - Diodes Division, carry Active product status, and meet all primary electrical and mechanical requirements. The 1N5401 base series provides identical voltage and current ratings with marginally lower forward voltage (1.2 V versus 1.3 V @ 3 A), resulting in reduced power dissipation. Both variants are ROHS3 compliant and suitable for new circuit designs. The difference between -E3/54 and -E3/73 variants relates to packaging tape specifications and does not affect electrical performance.

The GP30B-E3/54 is an Active substitute from the Vishay SUPERECTIFIER® series. It maintains identical voltage and current ratings with equivalent forward voltage characteristics. This part offers an extended operating temperature range (-65°C to 175°C) compared to the FR302G A0G (-55°C to 150°C), providing enhanced thermal performance for demanding applications. ROHS3 compliance is confirmed.

Alternative Substitute (Current Upgrade):

The 60S1-TP manufactured by Micro Commercial Co is rated for 6 A average rectified current, exceeding the 3 A specification of the FR302G A0G. This part maintains the 100 V reverse voltage rating and DO-201AD package configuration. However, the 60S1-TP carries a "Not For New Designs" product status, indicating manufacturer discontinuation or transition. This part is suitable only for legacy system maintenance or applications requiring higher current capacity where design revision is not feasible.

Frequently Asked Questions (FAQ)

Q: Can the 1N5401-E3/54 directly replace the FR302G A0G without circuit modification?

A: Yes. Both parts share identical voltage (100 V) and current (3 A) ratings, operate in the same DO-201AD axial through-hole package, and exhibit compatible forward voltage characteristics (1.2 V versus 1.3 V @ 3 A). The lower forward voltage of the 1N5401-E3/54 results in reduced power dissipation, which is beneficial for thermal management.

Q: What is the difference between the 1N5401-E3/54 and 1N5401-E3/73 variants?

A: Both variants are electrically identical. The suffix designations (-E3/54 and -E3/73) indicate different packaging tape specifications and supplier configurations. Selection between these variants depends on procurement requirements and tape reel specifications rather than electrical performance.

Q: Why does the GP30B-E3/54 have a longer reverse recovery time (5 µs) compared to the FR302G A0G (150 ns)?

A: The GP30B-E3/54 belongs to the SUPERECTIFIER® series, which prioritizes low forward voltage and thermal performance over switching speed. The extended reverse recovery time does not affect DC rectification applications but may impact high-frequency switching circuits. Verify application requirements before substitution in switching power supplies.

Q: Is the 60S1-TP suitable for new product designs?

A: No. The 60S1-TP carries a "Not For New Designs" product status, indicating manufacturer discontinuation. This part is reserved for legacy system maintenance only. For new designs, select the 1N5401-E3/54, 1N5401-E3/73, or GP30B-E3/54.

Q: Can the 60S1-TP (6 A rating) be used in place of the FR302G A0G (3 A rating)?

A: Yes, from an electrical compatibility standpoint. The 60S1-TP maintains the 100 V reverse voltage rating and DO-201AD package, with current capacity exceeding the original specification. However, the "Not For New Designs" status and higher capacitance (150 pF versus 30 pF) make this substitution suitable only for legacy applications or current upgrade scenarios where design revision is not feasible.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (1N5401-E3/54, 1N5401-E3/73, 60S1-TP, and GP30B-E3/54) are ROHS3 compliant and REACH unaffected, matching the compliance profile of the FR302G A0G.

Q: What is the minimum operating temperature range for substitute parts?

A: The FR302G A0G operates from -55°C to 150°C. The 1N5401 variants operate from -50°C to 150°C, which is acceptable for most applications. The GP30B-E3/54 offers the widest range (-65°C to 175°C), providing superior performance in extreme temperature environments. The 60S1-TP matches the original range (-55°C to 150°C).
