Engineering Selection Recommendations

All three parts—FR2M-LTP (Micro Commercial Co), FR2M (Diotec Semiconductor), and FR2M_R1_00001 (Panjit International Inc.)—are Active product status and ROHS3 compliant, meeting regulatory requirements for current applications.

FR2M (Diotec Semiconductor): This substitute maintains identical electrical specifications to the FR2M-LTP. It is suitable for direct replacement where inventory availability is a consideration, with 12,655 pieces in stock.

FR2M_R1_00001 (Panjit International Inc.): This substitute meets all mandatory electrical parameters with an improved reverse leakage current specification of 1 µA @ 1000 V compared to 5 µA @ 1000 V in the main part. This lower leakage characteristic may provide performance benefits in applications sensitive to leakage current. Inventory availability is 2,100 pieces.

Selection between substitutes should be based on availability, supply chain requirements, and application-specific performance needs related to reverse leakage current characteristics.

Frequently Asked Questions (FAQ)

Q: Can FR2M (Diotec Semiconductor) be used as a direct replacement for FR2M-LTP?

A: Yes. The FR2M from Diotec Semiconductor matches all critical electrical parameters including voltage rating (1000 V), current rating (2 A), forward voltage (1.3 V @ 2 A), reverse recovery time (500 ns), and package type (DO-214AA, SMB). Both parts are Active status and ROHS3 compliant.

Q: What is the difference between FR2M_R1_00001 and FR2M-LTP?

A: The FR2M_R1_00001 from Panjit International Inc. is electrically equivalent to the FR2M-LTP in all primary specifications. The key difference is the reverse leakage current: FR2M_R1_00001 specifies 1 µA @ 1000 V compared to 5 µA @ 1000 V for the FR2M-LTP. This lower leakage may be advantageous in applications where leakage current is a design constraint.

Q: Are all substitute parts in the same package?

A: Yes. All three parts use the DO-214AA (SMB) surface mount package, ensuring mechanical and thermal compatibility on printed circuit boards designed for the FR2M-LTP.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. The FR2M-LTP, FR2M (Diotec), and FR2M_R1_00001 (Panjit) are all ROHS3 compliant, meeting environmental and regulatory requirements for current manufacturing standards.

Q: What is the operating temperature range for these diodes?

A: All three parts operate across a junction temperature range of -50°C to 150°C, providing consistent thermal performance across the specified range.

Q: Can these parts be used interchangeably in high-frequency switching applications?

A: All three parts are classified as Fast Recovery diodes with a reverse recovery time of 500 ns, making them suitable for switching applications within this recovery time specification.
