Substitute Part Grouping Explanation

Substitution of the PSMN023-80LS,115 is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Drain-to-Source Voltage (Vdss): Must be equal to or greater than 80V
• Continuous Drain Current (Id): Must support the application's current requirements
• On-State Resistance (Rds On): Must be compatible with thermal and efficiency requirements
• Gate Threshold Voltage (Vgs(th)): Must be within compatible drive voltage ranges
• Operating Temperature Range: Must encompass -55°C to 150°C (TJ)
• Package Type: Surface mount configuration with exposed pad preferred for thermal performance
• Compliance: RoHS3 compliance and REACH unaffected status required

Identified Substitute Parts:

1. FDMC86324 (onsemi): Meets 80V Vdss requirement with 20A (Tc) continuous drain current and 23 mOhm Rds On. Active product status. Power33 package provides thermal management. Suitable for applications where 20A (Tc) current rating is sufficient.

2. IRFH5053TRPBF (Infineon Technologies): Exceeds 80V requirement with 100V Vdss rating and 46A (Tc) continuous drain current. Active product status. PQFN (5x6) package. Suitable for applications requiring higher voltage margin and current capability.

Parameter Comparison

Engineering Selection Recommendations

FDMC86324 Selection Criteria:

The FDMC86324 from onsemi is an active product with equivalent 80V Vdss rating and matching 23 mOhm Rds On specification. This substitute is appropriate for applications where the continuous drain current requirement does not exceed 20A (Tc). The device maintains full RoHS3 compliance and REACH unaffected status. The Power33 package provides thermal management suitable for surface mount assembly. Gate charge is lower at 18 nC compared to the original 21 nC, resulting in faster switching characteristics.

IRFH5053TRPBF Selection Criteria:

The IRFH5053TRPBF from Infineon Technologies is an active product with 100V Vdss rating, providing a 20V voltage margin above the original 80V specification. This device delivers 46A (Tc) continuous drain current, exceeding the original 34A rating. The on-state resistance of 18 mOhm is superior to the original 23 mOhm specification. This substitute is suitable for applications requiring higher current capacity and voltage headroom. The device maintains full RoHS3 compliance and REACH unaffected status. Moisture sensitivity level is MSL 2 (1 Year), compared to MSL 1 (Unlimited) for the original part.

Both substitute parts are active products with established supply chain availability, ensuring long-term component sourcing reliability compared to the obsolete PSMN023-80LS,115.

Frequently Asked Questions (FAQ)

Q: Can FDMC86324 directly replace PSMN023-80LS,115 in all applications?

A: FDMC86324 is suitable for applications where continuous drain current does not exceed 20A (Tc). The matching 80V Vdss and 23 mOhm Rds On specifications ensure electrical compatibility. Package differences (Power33 vs. 8-VDFN) require PCB layout verification for thermal performance and pin compatibility.

Q: What are the advantages of IRFH5053TRPBF over FDMC86324?

A: IRFH5053TRPBF provides higher continuous drain current (46A vs. 20A at Tc), lower on-state resistance (18 mOhm vs. 23 mOhm), and higher voltage rating (100V vs. 80V). These characteristics make it suitable for higher-power applications. However, gate charge is higher (36 nC vs. 18 nC), which may affect switching speed in certain circuit topologies.

Q: Are package differences between substitutes critical?

A: Yes. The original PSMN023-80LS,115 uses 8-VDFN Exposed Pad, while FDMC86324 uses 8-PowerTDFN and IRFH5053TRPBF uses 8-PowerVDFN. Pin assignments, thermal pad dimensions, and PCB footprints differ. PCB layout redesign and thermal analysis are required before substitution.

Q: Do all substitute parts meet compliance requirements?

A: Yes. Both FDMC86324 and IRFH5053TRPBF are RoHS3 compliant and REACH unaffected, matching the original part's compliance status. IRFH5053TRPBF has MSL 2 (1 Year) moisture sensitivity versus MSL 1 (Unlimited) for the original part, requiring appropriate handling during storage and assembly.

Q: Which substitute is recommended for new designs?

A: Selection depends on application current requirements. For applications requiring up to 20A (Tc), FDMC86324 provides a closer electrical match with lower gate charge. For applications requiring higher current capacity or voltage margin, IRFH5053TRPBF is appropriate. Both are active products with established supply availability.

Q: What parameters must be verified before substitution?

A: Verify continuous drain current requirement, on-state resistance thermal budget, gate drive voltage compatibility, switching frequency effects from gate charge differences, and PCB thermal design for the new package. Functional testing under application-specific conditions is required to confirm substitution suitability.
