Engineering Selection Recommendations

IXFH50N20 (Primary Part) The IXFH50N20 remains the primary selection when IXYS HiPerFET™ series devices are specified or when TO-247AD package geometry is required. This part is Active status with full RoHS3 and REACH compliance. Current inventory of 1230 pieces supports immediate procurement.

IRFP260NPBF (Upgrade Substitute) The IRFP260NPBF is qualified as an upgrade substitute based on matching voltage, current, and power ratings. This Infineon HEXFET® device offers improved on-resistance (40 mOhm vs. 45 mOhm) and extended operating temperature range (-55°C to 175°C vs. -55°C to 150°C). The TO-247AC package is mechanically compatible with TO-247-3 footprints. RoHS3 and REACH compliance are maintained. Inventory of 65300 pieces provides high availability. MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints.

IRFP260MPBF (Similar Substitute) The IRFP260MPBF is qualified as a similar substitute with identical electrical specifications to the IRFP260NPBF. Both Infineon parts share the same performance characteristics and compliance certifications. Inventory of 40300 pieces supports procurement. Selection between IRFP260NPBF and IRFP260MPBF is determined by packaging and supplier availability requirements.

All three parts are Active status devices with RoHS3 compliance and REACH Unaffected designation, suitable for direct substitution in applications where the specified electrical parameters are met.

Frequently Asked Questions (FAQ)

Q: Can IRFP260NPBF or IRFP260MPBF be used as direct replacements for IXFH50N20?

A: Yes. Both Infineon parts meet the core electrical specifications: 200V Vdss, 50A continuous drain current, and 300W power dissipation. All three devices are N-Channel MOSFETs with matching voltage and current ratings. The TO-247AC package used by the Infineon parts is mechanically compatible with the TO-247-3 footprint classification of the IXFH50N20 in through-hole applications.

Q: What are the differences between IRFP260NPBF and IRFP260MPBF?

A: Both parts are functionally identical with respect to the provided electrical parameters. They share the same Vdss (200V), Id (50A), power dissipation (300W), Rds On (40 mOhm @ 28A, 10V), gate charge (234 nC @ 10V), and operating temperature range (-55°C to 175°C). Selection between these two Infineon devices is based on packaging format and supplier availability.

Q: How does the IXFH50N20 compare to the Infineon substitutes in terms of on-resistance?

A: The IXFH50N20 has a maximum on-resistance of 45 mOhm at 25A and 10V gate voltage. The IRFP260NPBF and IRFP260MPBF both specify 40 mOhm at 28A and 10V gate voltage. The Infineon devices exhibit lower on-resistance, which reduces conduction losses in switching applications.

Q: Are there temperature range differences between these parts?

A: Yes. The IXFH50N20 operates from -55°C to 150°C (TJ). Both IRFP260NPBF and IRFP260MPBF extend the upper operating temperature to 175°C (TJ). This 25°C difference provides additional thermal margin in high-temperature environments.

Q: Do all three parts meet RoHS3 and REACH compliance requirements?

A: Yes. The IXFH50N20, IRFP260NPBF, and IRFP260MPBF are all RoHS3 Compliant and REACH Unaffected. All parts are suitable for applications requiring environmental compliance certification.

Q: What is the significance of the TO-247AD versus TO-247AC package designation?

A: Both TO-247AD and TO-247AC are TO-247-3 package classifications used for through-hole mounting. The designations reflect manufacturer-specific package variants. Both are mechanically compatible for through-hole PCB applications and share the same lead configuration and thermal characteristics for this device category.

Q: Is there a moisture sensitivity concern with these parts?

A: The IXFH50N20 has MSL (Moisture Sensitivity Level) listed as Not Applicable. The IRFP260NPBF and IRFP260MPBF both have MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints. All parts can be handled and stored without special moisture control measures.

Q: What inventory levels are available for each part?

A: IXFH50N20 has 1230 pieces in stock. IRFP260NPBF has 65300 pieces available. IRFP260MPBF has 40300 pieces available. The Infineon substitutes offer significantly higher inventory availability.
