Substitute Part Grouping Explanation

Substitute parts for the IRGPF40F are selected based on the following electrical and mechanical compatibility criteria:

Primary Substitution Criteria:

Voltage rating equal to or greater than 900V collector-emitter breakdown voltage
Current rating equal to or greater than 31A maximum collector current
Power dissipation capability equal to or greater than 160W
Standard input type configuration
Operating temperature range encompassing -55°C to 150°C
Through-hole mounting in TO-247-3 package family
Compatible TO-247 supplier device package variants (TO-247AC, TO-247AD)

Substitute Parts Identified:

IXGH20N100 (IXYS) — Exceeds voltage specification (1000V) with higher current rating (40A) and comparable power rating (150W). Active product status with ROHS3 compliance.
IXGH28N90B (IXYS) — Matches voltage specification (900V) with significantly higher current rating (51A) and power rating (200W). Active product status with ROHS3 compliance and HiPerFAST™ series designation.

Both substitute parts maintain TO-247-3 package compatibility and standard input type configuration required for direct functional replacement.

Recommended for applications requiring higher voltage margin (1000V vs. 900V rating)
Active product status ensures long-term supply chain availability
ROHS3 compliance supports regulatory requirements for new designs
Current rating (40A) provides 29% margin above IRGPF40F specification
Power rating (150W) is within 6% of original specification

IXGH28N90B Selection Criteria:

Recommended for applications requiring voltage specification match (900V) with performance headroom
Active product status with HiPerFAST™ series designation indicates advanced switching characteristics
ROHS3 compliance supports regulatory requirements
Current rating (51A) provides 65% margin above IRGPF40F specification
Power rating (200W) provides 25% margin above original specification
Lower Vce(on) (2.7V vs. 3.3V) indicates improved conduction efficiency

Both substitute parts are manufactured by IXYS with active product status, ensuring availability and technical support. Selection between IXGH20N100 and IXGH28N90B depends on application voltage requirements and thermal design considerations.

Frequently Asked Questions (FAQ)

Q: Can IXGH20N100 directly replace IRGPF40F in existing designs?

A: IXGH20N100 meets all electrical and mechanical substitution criteria. The higher voltage rating (1000V) provides additional design margin. TO-247AD package is mechanically compatible with TO-247AC footprints. Verify gate drive circuit compatibility with standard input type configuration.

Q: What is the primary difference between IXGH20N100 and IXGH28N90B?

A: IXGH20N100 operates at 1000V with 40A current rating. IXGH28N90B operates at 900V (matching IRGPF40F) with 51A current rating. IXGH28N90B provides lower on-state voltage (2.7V vs. 3V) and faster switching characteristics (100ns off-time vs. 350ns).

Q: Are TO-247AC and TO-247AD packages interchangeable?

A: TO-247AC and TO-247AD are both TO-247-3 package variants with identical mechanical footprints and pin configurations. Both are suitable for through-hole mounting on standard PCB layouts designed for TO-247-3 packages.

Q: Does RoHS compliance affect substitution decisions?

A: IRGPF40F is RoHS non-compliant. Both substitute parts (IXGH20N100 and IXGH28N90B) are ROHS3 compliant. For new designs or applications with regulatory requirements, ROHS3-compliant substitutes are required.

Q: What thermal considerations apply when substituting these IGBTs?

A: IXGH28N90B exhibits lower Vce(on) (2.7V vs. 3.3V), resulting in reduced conduction losses and lower junction temperature rise. Both substitutes maintain identical operating temperature range (-55°C to 150°C). Thermal design calculations should account for actual application current levels and switching frequency.

Q: Are gate charge and switching time specifications critical for substitution?

A: Gate charge and switching time are provided for IXGH20N100 (73 nC, 30ns/350ns) and IXGH28N90B (100 nC, 30ns/100ns) but not specified for IRGPF40F. These parameters affect gate drive circuit design. Verify gate driver capability with substitute part specifications before implementation.
