Substitute Part Grouping Explanation

Substitution of the IRGPF50F is determined by matching the following critical electrical and mechanical parameters:

Primary Matching Criteria:

Voltage - Collector Emitter Breakdown (Max): 900V
Current - Collector (Ic) (Max): 51A or greater
Vce(on) (Max) @ Vge, Ic: 2.7V @ 15V, 28A
Power - Max: 200W or greater
Input Type: Standard
Operating Temperature Range: -55°C to 150°C minimum
Mounting Type: Through Hole
Package / Case: TO-247-3

Package Compatibility: Substitute parts must utilize TO-247-3 package format. Variations in supplier device package designation (TO-247AC, TO-247AD, TO-247 IXTH, ISOPLUS247™) are acceptable provided the mechanical footprint and pin configuration remain compatible with TO-247-3 specifications.

All four substitute parts meet or exceed the primary electrical specifications of the IRGPF50F. Differences in secondary parameters such as switching energy, gate charge, and delay times reflect design improvements in active product lines while maintaining functional equivalence for the specified application envelope.

Engineering Selection Recommendations

IXGH28N90B is the primary substitute for direct replacement applications. This part maintains identical electrical specifications to the IRGPF50F (900V, 51A, 2.7V Vce(on), 200W) with active product status and ROHS3 compliance. The TO-247AD package variant is mechanically compatible with TO-247-3 footprints. This part is recommended for new designs and production transitions from the obsolete IRGPF50F.

IXYH24N90C3D1 provides an alternative substitute with active product status and ROHS3 compliance. While collector current is reduced to 44A, the part maintains the 900V voltage rating, 2.7V Vce(on) specification, and 200W power rating. This part is suitable for applications where the 44A current specification is sufficient. The operating temperature range matches the IRGPF50F at -55°C to 150°C.

IXYH24N90C3 offers the highest power dissipation capability at 240W with active product status and ROHS3 compliance. Collector current is rated at 46A. This part extends the operating temperature range to 175°C, providing additional thermal margin in high-temperature environments. The 900V voltage rating and 2.7V Vce(on) specification are maintained.

IXGR32N90B2D1 is a PT-type IGBT with active product status and ROHS3 compliance. This part features reduced collector current (47A) and power rating (160W) compared to the IRGPF50F. The ISOPLUS247™ package is mechanically compatible with TO-247-3 footprints. This part is suitable for applications where the 47A current and 160W power specifications are adequate.

All substitute parts are REACH Unaffected and classified as EAR99 for export control purposes, matching the regulatory status of the IRGPF50F.

Frequently Asked Questions (FAQ)

Q: Can IXGH28N90B directly replace IRGPF50F in existing PCB designs?

A: Yes. IXGH28N90B maintains identical electrical specifications (900V, 51A, 2.7V Vce(on), 200W) and operates within the same temperature range (-55°C to 150°C). The TO-247AD package is mechanically compatible with TO-247-3 footprints used by the IRGPF50F.

Q: What is the difference between TO-247AC and TO-247AD package variants?

A: Both TO-247AC and TO-247AD are TO-247-3 package variants with identical mechanical footprints and pin configurations. The letter designation indicates manufacturer-specific package nomenclature. Both are compatible with standard TO-247-3 PCB layouts.

Q: Why does IXGR32N90B2D1 have lower current and power ratings than IRGPF50F?

A: IXGR32N90B2D1 is a PT-type IGBT with different internal architecture optimized for specific switching characteristics. The 47A current and 160W power ratings are the specified maximums for this device. Applications requiring 51A and 200W should select IXGH28N90B or IXYH24N90C3 instead.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four substitute parts are ROHS3 compliant. The original IRGPF50F is RoHS non-compliant. Designs transitioning to substitute parts will achieve RoHS3 compliance.

Q: Can IXYH24N90C3 be used in applications requiring -55°C to 150°C operation?

A: Yes. IXYH24N90C3 operates across -55°C to 175°C, which exceeds the -55°C to 150°C requirement of the IRGPF50F. The extended upper temperature limit provides additional thermal margin.

Q: What is the significance of the GenX3™ and XPT™ series designation on IXYH24N90C3 and IXYH24N90C3D1?

A: GenX3™ and XPT™ are IXYS product series designations indicating advanced IGBT technology generations. These designations reflect design improvements in switching performance and gate charge characteristics while maintaining functional equivalence with the IRGPF50F for the specified application envelope.

Q: Are there inventory considerations when selecting a substitute?

A: Yes. Current inventory levels vary: IXGH28N90B (5625 pcs), IXYH24N90C3D1 (1048 pcs), IXYH24N90C3 (798 pcs), and IXGR32N90B2D1 (998 pcs). IXGH28N90B offers the highest availability for immediate procurement.

Q: Do all substitute parts have identical gate charge specifications?

A: No. Gate charge varies across substitute parts: IXGH28N90B (100 nC), IXGR32N90B2D1 (89 nC), IXYH24N90C3 (40 nC), and IXYH24N90C3D1 (40 nC). Lower gate charge reduces driver power requirements. Applications with gate driver constraints should evaluate this parameter.
