IRFP450PBF Equivalent & Substitute Parts Reference

Part Overview

The IRFP450PBF is a N-Channel MOSFET manufactured by Infineon Technologies, designed for high voltage and current applications with a TO-247AC through-hole package. Key electrical attributes include a drain-to-source voltage of 500 V and a continuous drain current of 14A at 25°C. With a maximum power dissipation of 190W and RoHS3 compliance, it is suitable for rigorous industrial environments. The part status is listed as obsolete, emphasizing the need to identify parametric equivalents and substitutes with matching electrical and mechanical specifications for direct replacement in designs.

Substitute Part Grouping Explanation

Substitute parts for the IRFP450PBF are selected based strictly on matching categories and electrical/mechanical parameters: drain-to-source voltage, continuous drain current, drive voltage, on-resistance at specified conditions, gate threshold voltage, gate charge, gate-source voltage, input capacitance, power dissipation, operating temperature, mounting type, package type, RoHS/REACH status, and product status. Only parts with identical or explicitly matched values across these key criteria qualify as equivalent substitutes.

Engineering Selection Recommendations

Component selection for the IRFP450PBF and its substitute, IRFP450PBF, is supported by identical compliance statuses, including RoHS3 and REACH certification. The ECCN and HTSUS codes are consistent, permitting direct interchange in designs subject to regulatory requirements. Given both parts are listed as obsolete, inventory check is required for procurement.

Frequently Asked Questions (FAQ)

Q1: What parameters must match to qualify IRFP450PBF substitutes?
A1: Required matching parameters include drain-to-source voltage, continuous drain current, drive voltage, on-resistance, gate threshold voltage, gate charge, maximum gate-source voltage, input capacitance, maximum power dissipation, operating temperature range, mounting type, package/case, RoHS status, REACH status, ECCN, HTSUS, and product status.

Q2: Is package/case matching essential for direct substitution?
A2: Yes, IRFP450PBF substitutes must have the same supplier device package (TO-247AC) and package/case (TO-247-3) to ensure equivalent mechanical fit and compatibility.

Q3: How does product status affect substitute selection?
A3: Both the main part and substitute are classified as obsolete. Selection is determined by existing inventory and strict parameter equivalence.

Q4: Are compliance certifications required to match for safe substitution?
A4: Yes. RoHS3 and REACH compliance must be identical between the main part and substitutes for applications requiring environmental regulatory adherence.

Q5: Can other IRFP series products substitute if they match all listed parameters?
A5: Substitute selection is limited to parts explicitly listed and verified by the provided parameters. No other parts can be considered unless all attributes provided are matched exactly.
