FRA802GF-BP Equivalent & Substitute Parts

Part Overview

The FRA802GF-BP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 100V DC reverse voltage and 8A average rectified current in a through-hole TO-220-2 isolated tab package. This component is classified as obsolete, making identification of equivalent and substitute parts necessary for ongoing design support, maintenance, and production continuity. The diode features fast recovery characteristics with a reverse recovery time of 150 ns and operates across a junction temperature range of -55°C to 150°C.

Mandatory Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 100V
Current - Average Rectified (Io): 8A
Mounting Type: Through Hole
Package / Case: TO-220-2 configuration
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
Operating Temperature Range: -55°C to 150°C minimum

Acceptable Variation Parameters:

Voltage - Forward (Vf) (Max) @ If: May vary within design margin

Engineering Selection Recommendations

The HERAF802G C0G from Taiwan Semiconductor Corporation is a qualified substitute for the obsolete FRA802GF-BP. Both components are ROHS3 compliant and operate within identical voltage, current, and temperature specifications. The substitute part offers improved electrical performance characteristics, including lower forward voltage drop (1.0V versus 1.3V at 8A) and significantly faster reverse recovery time (50ns versus 150ns), which may provide benefits in high-frequency switching applications.

The substitute part maintains active product status, ensuring continued availability and supply chain reliability compared to the obsolete original part. Both components utilize through-hole mounting in TO-220-2 package configurations, supporting direct mechanical and electrical compatibility in existing circuit board designs.

Frequently Asked Questions (FAQ)

Q: Can the HERAF802G C0G be used as a direct replacement for the FRA802GF-BP in existing designs?

A: Yes. Both components share identical voltage ratings (100V), current ratings (8A), temperature operating range (-55°C to 150°C), and package type (TO-220-2 through-hole). The substitute part meets all mandatory electrical and mechanical parameters required for direct substitution.

Q: What is the difference between the TO-220-2 Isolated Tab and TO-220-2 Full Pack configurations?

A: Both are TO-220-2 package types suitable for through-hole mounting. The isolated tab and full pack designations refer to thermal and electrical isolation characteristics of the tab structure. Both configurations are mechanically and electrically compatible for standard circuit board applications.

Q: Does the faster reverse recovery time of the HERAF802G C0G affect circuit compatibility?

A: No. A faster reverse recovery time (50ns versus 150ns) is a performance improvement that does not create compatibility issues. The substitute part will function correctly in all applications designed for the original FRA802GF-BP.

Q: Are there any compliance or certification differences between the two parts?

A: Both parts are ROHS3 compliant. The HERAF802G C0G includes REACH Unaffected status. Both components carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: Why is the FRA802GF-BP classified as obsolete?

A: The FRA802GF-BP is no longer in active production. The HERAF802G C0G from Taiwan Semiconductor Corporation is an active product that provides equivalent functionality with improved electrical characteristics, making it the recommended substitute for new designs and ongoing production support.

Q: What inventory considerations should be evaluated when transitioning from FRA802GF-BP to HERAF802G C0G?

A: Both parts are currently available in stock (946 pcs and 947 pcs respectively). Transition planning should account for design validation, circuit board layout compatibility verification, and supply chain qualification of the substitute manufacturer.
