Substitute Part Grouping Explanation

Substitution of the FR106GP-TP is determined by equivalence in the following critical parameters:

Voltage Rating: 800 V DC reverse voltage (Vr)
Current Rating: 1 A average rectified current (Io)
Forward Voltage: 1.3 V maximum at 1 A forward current
Reverse Recovery Time: 500 ns (fast recovery classification)
Reverse Leakage Current: 5 µA at 800 V
Mounting Configuration: Through-hole axial package (DO-41 or DO-204AL equivalent)
Temperature Range: -55°C to 150°C junction operating temperature
Compliance: ROHS3 compliant, REACH unaffected

Parts are grouped into two categories:

Parametric Equivalents: Parts matching all critical electrical parameters and package specifications, differing only in manufacturer, product status, or packaging format (Tape & Reel vs. Cut Tape).

Similar Parts: Parts meeting voltage and current ratings with variations in forward voltage, reverse recovery time, or capacitance that remain within acceptable operating margins for general-purpose rectification applications.

Engineering Selection Recommendations

Primary Equivalents for Direct Replacement

The 1N4947GP-TP, FR106T-G, FR106G, and FR106G R1G are direct parametric equivalents to the FR106GP-TP. All maintain identical voltage and current ratings, forward voltage characteristics, and reverse leakage specifications. The 1N4947GP-TP features improved reverse recovery time (250 ns versus 500 ns), providing faster switching performance while maintaining full electrical compatibility. FR106T-G and FR106G variants are manufactured by alternative suppliers (Comchip Technology and Taiwan Semiconductor Corporation) and carry Active product status, ensuring continued availability and support.

Secondary Alternative for Performance Optimization

The UF4006 B0G meets the 800 V and 1 A specifications but exhibits higher forward voltage (1.7 V versus 1.3 V) and significantly faster reverse recovery time (75 ns versus 500 ns). This part is suitable for applications where reduced switching losses and faster recovery characteristics provide system-level benefits, provided the higher forward voltage drop is acceptable within the circuit design margins.

Compliance and Availability

All substitute parts listed are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the FR106GP-TP. The FR106G variant offers the highest inventory availability (10,626 pieces), while 1N4947GP-TP, FR106T-G, and FR106G R1G maintain substantial stock levels. Selection should prioritize parts with Active product status to ensure long-term sourcing stability.

Frequently Asked Questions (FAQ)

Q: Can the 1N4947GP-TP replace the FR106GP-TP in all applications?

A: Yes. The 1N4947GP-TP is a parametric equivalent with identical voltage, current, and forward voltage ratings. The faster reverse recovery time (250 ns) is a performance enhancement that does not compromise compatibility. Both parts are rated for -55°C to 150°C junction temperature and are ROHS3 compliant.

Q: What is the difference between FR106G and FR106G R1G?

A: Both parts are parametric equivalents manufactured by Taiwan Semiconductor Corporation with identical electrical specifications. The designation difference reflects manufacturing or packaging variants. Both maintain 800 V reverse voltage, 1 A current rating, and 500 ns reverse recovery time. Selection between them depends on packaging availability and supplier preference.

Q: Is the UF4006 B0G suitable as a substitute despite higher forward voltage?

A: The UF4006 B0G meets the 800 V and 1 A requirements and is electrically compatible. The forward voltage increase from 1.3 V to 1.7 V results in approximately 0.4 V additional voltage drop per diode. This must be evaluated within the specific circuit design to confirm acceptable power dissipation and voltage regulation margins. The significantly faster recovery time (75 ns) may provide switching performance benefits in high-frequency applications.

Q: What packaging differences exist between substitute parts?

A: The FR106GP-TP is supplied in Tape & Reel (TR) format in DO-41 package. Equivalent parts are available in identical DO-41 TR packaging (1N4947GP-TP, FR106T-G) or in Cut Tape (CT) format (FR106G). The UF4006 B0G uses DO-204AL (DO-41 equivalent) package designation. All are through-hole axial components with identical mechanical footprints and pin configurations.

Q: Are all substitute parts rated for the same temperature range?

A: Yes. All substitute parts listed maintain the -55°C to 150°C junction operating temperature range, ensuring thermal compatibility across the full operating envelope.

Q: Why is the FR106GP-TP marked as Not For New Designs?

A: This designation indicates the part has been superseded by the manufacturer. Active alternatives such as 1N4947GP-TP, FR106T-G, FR106G, and FR106G R1G provide equivalent or improved performance with continued manufacturer support and availability assurance.
