Voltage - DC Reverse (Vr) (Max): 50 V
Current - Average Rectified (Io): 2 A
Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 2 A or lower
Reverse Recovery Time (trr): 150 ns or lower
Current - Reverse Leakage @ Vr: 5 µA @ 50 V or lower
Mounting Type: Through Hole
Package / Case: DO-204AC, DO-15, Axial
Operating Temperature - Junction: -55°C ~ 150°C

Engineering Selection Recommendations

FR201GP-AP is the primary direct substitute for the FR201-AP. Both parts are manufactured by Micro Commercial Co and share identical electrical specifications. The FR201GP-AP maintains active product status, ensuring long-term availability and supply chain continuity. This part is recommended as the first choice for replacement applications.

FR201GB-G (Comchip Technology) and FR201G A0G (Taiwan Semiconductor Corporation) are parametric equivalents that meet all electrical and mechanical requirements of the FR201-AP. Both parts are active products with ROHS3 compliance and identical voltage, current, and temperature ratings. These parts are suitable alternatives when FR201GP-AP availability is constrained.

HER201G A0G (Taiwan Semiconductor Corporation) is a parametric equivalent with superior performance characteristics. This part features a lower forward voltage drop (1 V @ 2 A versus 1.3 V @ 2 A) and faster reverse recovery time (50 ns versus 150 ns). The HER201G A0G is suitable for applications where reduced power dissipation and faster switching performance are beneficial.

FR201G (Taiwan Semiconductor Corporation) is a parametric equivalent with identical electrical specifications to the FR201-AP. This part is active and ROHS3 compliant, providing an alternative source for procurement.

All substitute parts maintain through-hole axial packaging compatibility, operating temperature range, and regulatory compliance with the original FR201-AP specification.

Frequently Asked Questions (FAQ)

Q: Can FR201GP-AP be used as a direct replacement for FR201-AP?

A: Yes. The FR201GP-AP is manufactured by the same company (Micro Commercial Co) and shares identical electrical specifications with the FR201-AP, including voltage rating, current rating, forward voltage drop, and reverse recovery time.

Q: What is the difference between FR201G and FR201G A0G?

A: Both parts are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications. The difference is in the part number suffix, which typically indicates packaging or date code variations. Both are parametric equivalents to the FR201-AP.

Q: Is HER201G A0G a suitable substitute despite the different part number prefix?

A: Yes. The HER201G A0G is manufactured by Taiwan Semiconductor Corporation and meets all electrical and mechanical requirements of the FR201-AP. The different prefix (HER versus FR) indicates a different product line within the manufacturer's portfolio, but the electrical performance is equivalent or superior. The HER201G A0G features lower forward voltage drop and faster reverse recovery time.
