APT5015BVRG N-Channel 500V 32A MOSFET Equivalent & Substitute Parts

Part Overview

The APT5015BVRG is an N-Channel 500V 32A through-hole MOSFET manufactured by Microchip Technology in the POWER MOS V® series. This device operates in the TO-247 [B] package and is designed for high-voltage switching applications requiring continuous drain current of 32A at 25°C case temperature. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching or exceeding critical electrical parameters: drain-to-source voltage (Vdss), continuous drain current (Id), on-state resistance (Rds On), and gate charge characteristics. Substitutes must maintain compatible through-hole mounting in TO-247 package variants to ensure direct circuit board compatibility.

Substitute Part Grouping Explanation

Substitution logic for the APT5015BVRG is based on the following critical parameters:

Voltage Rating (Vdss): All substitute parts must maintain 500V drain-to-source voltage rating to ensure safe operation in the intended circuit topology.

Current Rating (Id): Substitute parts must support continuous drain current of 32A or greater at 25°C case temperature. Parts with higher current ratings provide design margin and thermal headroom.

On-State Resistance (Rds On): Maximum on-state resistance must not exceed 150mOhm at the specified gate-source voltage (10V) and current conditions. Lower Rds On values reduce conduction losses and heat dissipation.

Gate Charge (Qg): Gate charge at 10V must remain within acceptable limits to maintain switching speed and driver compatibility. Lower gate charge reduces switching losses.

Package Compatibility: All substitutes use through-hole mounting in TO-247 package variants (TO-247-3, TO-247AC, TO-247AD, ISOPLUS247™, PLUS247™-3). These packages are mechanically and electrically interchangeable for circuit board layout purposes.

Compliance: All substitute parts maintain RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring regulatory and environmental compatibility.

Engineering Selection Recommendations

Primary Substitutes (Direct Equivalents):

IRFP32N50KPBF and IXFH36N50P are the closest electrical equivalents to the APT5015BVRG. Both maintain 500V Vdss rating and support 32A or greater continuous drain current. IRFP32N50KPBF matches the 32A current specification exactly with slightly higher Rds On (160mOhm vs. 150mOhm), while IXFH36N50P provides 36A current capability with comparable on-state resistance. Both parts are Active status with full RoHS3 compliance.

Secondary Substitutes (Higher Current Capability):

IXFH42N50P2 and IXTX46N50L provide enhanced current ratings (42A and 46A respectively) while maintaining 500V voltage rating. These parts offer superior thermal performance and design margin. IXFH42N50P2 features lower Rds On (145mOhm) than the main part, reducing conduction losses. IXFH42N50P2 carries Last Time Buy status; IXTX46N50L remains Active.

Lower Current Alternatives (Reduced Voltage Rating):

IRFP360PBF and SIHG25N40D-GE3 operate at 400V Vdss with reduced current ratings (23A and 25A respectively). These parts are suitable only for applications where 400V voltage rating is acceptable and current requirements do not exceed their specifications. Both maintain Active status and RoHS3 compliance.

Compliance and Regulatory Considerations:

All recommended substitutes maintain RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with modern manufacturing and environmental standards. IRFP32N50KPBF carries REACH Affected status; all other substitutes are either REACH Unaffected or Vendor Undefined. All parts share EAR99 export classification and identical HTSUS commodity code (8541.29.0095) with the main part.

Frequently Asked Questions (FAQ)

Q: Can IRFP32N50KPBF directly replace APT5015BVRG in existing designs?

A: Yes. IRFP32N50KPBF matches the 500V voltage rating and 32A current specification. Rds On is 160mOhm versus 150mOhm for the APT5015BVRG, resulting in slightly higher conduction losses. Gate charge is lower (190nC vs. 300nC), enabling faster switching. TO-247AC package is mechanically compatible with TO-247 [B] for through-hole mounting.

Q: What is the advantage of using IXFH36N50P over the main part?

A: IXFH36N50P provides 36A continuous drain current versus 32A, offering 12.5% additional current capacity. Gate charge is significantly lower (93nC vs. 300nC), reducing switching losses and driver stress. On-state resistance is comparable (170mOhm vs. 150mOhm). The trade-off is slightly higher input capacitance (5500pF vs. 5280pF).

Q: Are 400V rated parts (IRFP360PBF, SIHG25N40D-GE3) suitable substitutes?

A: No, not as direct substitutes. These parts operate at 400V maximum drain-to-source voltage, which is 100V lower than the APT5015BVRG. Use only if the circuit topology and application requirements explicitly allow 400V operation. Current ratings are also reduced (23A and 25A respectively).

Q: What is the difference between TO-247 package variants (TO-247 [B], TO-247AC, TO-247AD)?

A: All variants are mechanically and electrically compatible through-hole packages with identical pin configurations and spacing. TO-247 [B] is the Microchip designation; TO-247AC is Vishay's variant; TO-247AD is IXYS's variant. Substitution between variants does not require circuit board redesign.

Q: Why does IXFH42N50P2 show Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this part. While currently available in inventory (5580 pcs), future availability is not guaranteed. For new designs, select Active status parts such as IXFH36N50P or IXTX46N50L.

Q: How does gate charge affect circuit performance?

A: Gate charge (Qg) determines the energy required to switch the MOSFET on and off. Lower gate charge reduces switching losses and allows faster switching speeds. IXFH36N50P (93nC) and IXFH30N50Q3 (62nC) have significantly lower gate charge than APT5015BVRG (300nC), enabling more efficient driver operation and reduced EMI.

Q: Can IXTX46N50L be used in applications requiring exactly 32A?

A: Yes. IXTX46N50L supports 46A continuous drain current, well above the 32A requirement. The part operates safely at lower current levels. However, the higher current rating results in increased input capacitance (7000pF vs. 5280pF) and gate charge (260nC vs. 300nC), which may affect switching characteristics and driver requirements.

Q: What inventory levels are available for each substitute?

A: IRFP32N50KPBF: 7245 pcs; IXFH36N50P: 2100 pcs; IXFH30N50Q3: 1152 pcs; IXTH30N50P: 888 pcs; IXFR44N50Q3: 1047 pcs; IXTX46N50L: 1115 pcs; IXFH42N50P2: 5580 pcs; IRFP360PBF: 18295 pcs; SIHG25N40D-GE3: 1089 pcs. Main part APT5015BVRG: 1060 pcs.
