Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the STP16N50M2 are selected based on the following critical parameters:

Primary Matching Criteria:

• Drain to Source Voltage (Vdss): 500V minimum
• Continuous Drain Current (Id): 13A minimum at 25°C
• Mounting Type: Through Hole TO-220-3 package
• FET Type: N-Channel MOSFET
• Operating Temperature Range: -55°C to 150°C

Secondary Compatibility Factors:

• Rds On (Max): 280 mOhm or lower for equivalent performance
• Gate Charge (Qg): Comparable switching characteristics
• Power Dissipation: Sufficient thermal handling capability
• RoHS3 Compliance and REACH Unaffected status

The substitute parts listed meet or exceed the primary matching criteria. Variations in secondary parameters reflect different manufacturing series and design approaches while maintaining functional equivalence in the specified voltage and current ratings.

Parameter Comparison

Engineering Selection Recommendations

FDP20N50F (onsemi UniFET™)

The FDP20N50F is an active product with 500V Vdss rating and 20A continuous drain current, exceeding the STP16N50M2 specifications. This part provides improved current handling and power dissipation (250W vs. 110W). RoHS3 compliance and REACH unaffected status align with regulatory requirements. Suitable for applications requiring higher current capacity within the same voltage class.

IPP50R280CEXKSA1 (Infineon CoolMOS™)

The IPP50R280CEXKSA1 maintains exact voltage and current ratings (500V, 13A) as the STP16N50M2, with identical Rds On specification (280 mOhm). This part is an active product with CoolMOS™ technology offering optimized switching characteristics. RoHS3 compliance and REACH unaffected status are confirmed. Recommended for direct functional replacement where pin-compatible TO-220-3 mounting is required.

IXFP26N50P3 (IXYS HiPerFET™)

The IXFP26N50P3 is an active product rated for 500V Vdss with 26A continuous drain current, providing significant current margin over the STP16N50M2. This part features lower Rds On (230 mOhm) and substantially higher power dissipation capability (500W). RoHS3 compliance and REACH unaffected status are confirmed. Suitable for applications requiring enhanced thermal performance and current handling.

FDP19N40 (onsemi UniFET™)

The FDP19N40 operates at 400V Vdss, which is below the STP16N50M2 specification of 500V. This part is classified as obsolete. Substitution is limited to applications where 400V voltage rating is acceptable and current requirements do not exceed 19A.

Frequently Asked Questions (FAQ)

Q: Can the FDP20N50F directly replace the STP16N50M2?

A: Yes. The FDP20N50F maintains the same 500V Vdss rating and exceeds the 13A current requirement with 20A capability. Both devices use TO-220-3 Through Hole packaging. The FDP20N50F is an active product, whereas the STP16N50M2 is obsolete. Pin configuration compatibility must be verified for the specific application circuit.

Q: What is the key difference between the IPP50R280CEXKSA1 and the STP16N50M2?

A: Both devices share identical electrical ratings: 500V Vdss, 13A continuous drain current, and 280 mOhm Rds On. The primary difference is manufacturing technology (CoolMOS™ vs. MDmesh™ M2) and product status (active vs. obsolete). The IPP50R280CEXKSA1 uses a PG-TO220-3-1 package variant, which is mechanically compatible with standard TO-220-3 footprints.

Q: Is the IXFP26N50P3 suitable for all STP16N50M2 applications?

A: The IXFP26N50P3 exceeds STP16N50M2 specifications in current (26A vs. 13A) and power dissipation (500W vs. 110W) while maintaining 500V Vdss rating. It is suitable for applications where higher current capacity and thermal performance are beneficial or required. Pin configuration compatibility must be confirmed for the specific circuit design.

Q: Why is the FDP19N40 listed as a substitute if it has a lower voltage rating?

A: The FDP19N40 is included in the substitute list based on the provided input parameters. However, its 400V Vdss rating is below the STP16N50M2 specification of 500V. Substitution is only appropriate for applications where the actual operating voltage does not exceed 400V and current requirements remain within the 19A limit.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (FDP20N50F, FDP19N40, IPP50R280CEXKSA1, and IXFP26N50P3) are RoHS3 compliant and have REACH unaffected status, matching the regulatory compliance of the STP16N50M2.

Q: What should be considered when selecting between substitute parts?

A: Selection depends on application requirements: voltage rating (all substitutes maintain 500V except FDP19N40 at 400V), current capacity (FDP20N50F at 20A, IXFP26N50P3 at 26A provide margin), power dissipation capability, and product availability. The IPP50R280CEXKSA1 provides the closest electrical match to the STP16N50M2. All substitutes use Through Hole TO-220-3 or compatible packaging.
