Engineering Selection Recommendations

Primary Substitutes (Direct Equivalents):

FR107GP-AP, 1N4948GP-AP, FR107G, BA159-E3/73, FR107A-G, and PG1010R_AY_00001 are direct electrical equivalents to the FR107-AP. All maintain the 1000 V reverse voltage rating, 1 A average rectified current, 1.3 V forward voltage drop, and 500 ns fast recovery time. These parts are manufactured by Micro Commercial Co, Taiwan Semiconductor Corporation, Vishay General Semiconductor, Comchip Technology, and Panjit International Inc., all with active product status. Selection among these equivalents should be based on packaging preference (Tape & Box, Cut Tape, or standard packaging), manufacturer availability, and inventory levels.

Secondary Consideration (Limited Current Rating):

GI250-1-E3/54 is classified as a similar part due to its reduced average rectified current rating of 250 mA compared to the 1 A requirement of the FR107-AP. This part is suitable only for applications where the actual circuit current does not exceed 250 mA. Additionally, GI250-1-E3/54 exhibits different forward voltage characteristics (3.5 V @ 250 mA) and standard recovery time (2 µs) rather than fast recovery. This part is not recommended as a direct substitute for the FR107-AP in circuits designed for 1 A operation.

Compliance and Certification:

All recommended substitute parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited). All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080, with the exception of GI250-1-E3/54, which is classified under HTSUS 8541.10.0070. REACH status is unaffected for all active parts.

Frequently Asked Questions (FAQ)

Q: Can FR107GP-AP be used as a direct replacement for FR107-AP?

A: Yes. FR107GP-AP is manufactured by the same supplier (Micro Commercial Co) and maintains identical electrical specifications: 1000 V reverse voltage, 1 A average rectified current, 1.3 V forward voltage drop at 1 A, and 500 ns reverse recovery time. The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Box). Both use the DO-41 package.

Q: What is the difference between FR107G and BA159-E3/73?

A: Both parts meet the electrical requirements of the FR107-AP with 1000 V, 1 A, 1.3 V forward voltage, and 500 ns recovery time. FR107G is manufactured by Taiwan Semiconductor Corporation and supplied in Cut Tape packaging with 2400 pieces in inventory. BA159-E3/73 is manufactured by Vishay General Semiconductor and supplied in Cut Tape packaging with 10359 pieces in inventory. The capacitance specifications differ slightly (10 pF for FR107G versus 12 pF for BA159-E3/73 at 4 V, 1 MHz), but both are within acceptable ranges for general purpose rectification.

Q: Is PG1010R_AY_00001 suitable for the FR107-AP application?

A: Yes. PG1010R_AY_00001 manufactured by Panjit International Inc. meets all critical electrical parameters: 1000 V reverse voltage, 1 A average rectified current, 1.3 V forward voltage drop, and 500 ns fast recovery time. The reverse leakage current is lower (1 µA @ 1000 V versus 5 µA), which is advantageous. The part is supplied in Cut Tape packaging with 5825 pieces in inventory.

Q: Why is GI250-1-E3/54 listed as a similar part rather than a direct substitute?

A: GI250-1-E3/54 has a reduced average rectified current rating of 250 mA, which is one-quarter of the FR107-AP's 1 A rating. Additionally, the forward voltage drop is 3.5 V @ 250 mA, significantly higher than the 1.3 V @ 1 A of the FR107-AP. The reverse recovery time is 2 µs (standard recovery) rather than 500 ns (fast recovery). This part is suitable only for applications with maximum circuit currents not exceeding 250 mA and where the higher forward voltage drop is acceptable.

Q: What packaging options are available for FR107-AP substitutes?

A: Substitute parts are available in multiple packaging formats: Tape & Box (TB) for FR107GP-AP and FR107A-G, Cut Tape (CT) for FR107G, BA159-E3/73, and PG1010R_AY_00001, and Tape & Reel (TR) for GI250-1-E3/54. All parts use the DO-41 or DO-204AL (DO-41) through-hole package, which are mechanically compatible. Selection of packaging format depends on procurement volume and assembly process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the FR107-AP. All parts are suitable for applications requiring RoHS3 certification.

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

A: Most substitute parts operate from -55°C to 150°C junction temperature, matching the FR107-AP. BA159-E3/73 operates from -65°C to 125°C, providing a lower minimum temperature but a lower maximum temperature. GI250-1-E3/54 operates from -65°C to 175°C, providing both extended low and high temperature operation. Application requirements should determine whether these temperature range variations are acceptable.
