STP16NK60Z Equivalent & Substitute Parts

Part Overview

The STP16NK60Z is an N-Channel 600V 14A MOSFET manufactured by STMicroelectronics in the SuperMESH™ series, housed in a TO-220-3 through-hole package. This device is classified as obsolete, indicating discontinuation from active production. The 600V drain-to-source voltage rating and 14A continuous drain current make it suitable for high-voltage switching applications requiring moderate current handling.

Due to its obsolete status, equivalent and substitute parts are necessary for ongoing design support, maintenance, and new production requirements. Substitute devices must maintain compatibility with the original electrical specifications and mechanical form factor while offering active or alternative product status from current manufacturers.

Substitute Part Grouping Explanation

Substitution of the STP16NK60Z is determined by the following critical parameters:

Voltage Rating Compatibility: The drain-to-source voltage (Vdss) must equal or exceed 600V. Substitute parts with higher voltage ratings (650V, 700V, 800V) are acceptable as they provide additional voltage margin.

Current Rating Compatibility: The continuous drain current (Id) must meet or exceed 14A at 25°C. Substitute parts with equal or higher current ratings maintain functional equivalence.

On-State Resistance (Rds On): Lower Rds On values indicate improved efficiency and reduced power dissipation. The original part specifies 420mOhm at 7A, 10V. Substitute parts with lower Rds On values provide performance enhancement.

Package and Mounting: All substitute parts must use through-hole mounting in TO-220 or compatible package variants (TO-220-3, ISOPLUS220™) to ensure mechanical and thermal compatibility with existing PCB designs.

Gate Charge (Qg): Lower gate charge values reduce switching losses and gate drive requirements. This parameter influences circuit performance but does not prevent substitution.

Compliance and Status: RoHS3 compliance and REACH unaffected status are maintained across all listed substitutes, ensuring regulatory compatibility.

Engineering Selection Recommendations

Direct Electrical Equivalents (600V, ≥11A):

STP13N60M2, AOT11S60L, and FCP11N60F provide 600V voltage rating with 11A continuous drain current. These parts are mechanically compatible with TO-220-3 through-hole mounting. STP13N60M2 carries active product status from STMicroelectronics, making it the preferred choice for new designs requiring direct voltage and package compatibility. AOT11S60L and FCP11N60F are marked "Not For New Designs," limiting their use to legacy system support.

Enhanced Performance Alternatives (600V, ≥10.6A):

IPP60R299CPXKSA1 and IPP60R380E6XKSA1 from Infineon Technologies maintain 600V ratings with current ratings of 11A and 10.6A respectively. Both feature significantly lower on-state resistance compared to the original part, reducing power dissipation. Both are classified "Not For New Designs," suitable for replacement applications only.

Higher Voltage Alternatives (≥650V):

IPP80R450P7XKSA1 (800V, 11A, Active status) and IXKC20N60C (600V, 15A, Active status) provide extended voltage margin or higher current capacity. IPP80R450P7XKSA1 is recommended for applications requiring enhanced voltage headroom. IXKC20N60C uses ISOPLUS220™ packaging, which differs mechanically from standard TO-220-3 and requires PCB layout verification.

Lower Current Alternatives:

IXTP8N70X2 (700V, 8A) and IXTP8N70X2M (700V, 4A) provide higher voltage ratings but reduced current capacity. These are suitable only for applications with current requirements below 8A.

Compliance Verification:

All listed substitutes maintain RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can STP13N60M2 directly replace STP16NK60Z?

A: STP13N60M2 is electrically compatible for applications requiring up to 11A continuous drain current at 600V. The original STP16NK60Z is rated for 14A. Direct substitution is valid only if the application current requirement does not exceed 11A. Both parts use TO-220-3 through-hole packaging and are mechanically interchangeable.

Q: What is the difference between TO-220-3 and ISOPLUS220™ packages?

A: Both are through-hole packages with three leads. ISOPLUS220™ (used by IXKC20N60C) features an isolated tab design, whereas standard TO-220-3 has a grounded tab. PCB layout and thermal management designs differ between these packages. Mechanical substitution requires PCB modification.

Q: Why do some substitute parts have lower power dissipation ratings than the original?

A: Power dissipation depends on on-state resistance (Rds On) and application current. Lower Rds On values reduce resistive losses. Parts with lower power dissipation ratings may still be suitable if the application current is lower than the original design specification.

Q: Is IPP80R450P7XKSA1 suitable for a 600V application?

A: Yes. IPP80R450P7XKSA1 is rated for 800V drain-to-source voltage, providing 200V additional margin above 600V. Higher voltage ratings do not prevent operation at lower voltages. This part is suitable for 600V applications and offers enhanced voltage safety margin.

Q: What does "Not For New Designs" status mean?

A: This designation indicates the manufacturer has discontinued active support and recommends alternative parts for new product development. These parts remain available for existing system maintenance and legacy support but should not be selected for new designs.

Q: Can IXTP8N70X2 replace STP16NK60Z in all applications?

A: No. IXTP8N70X2 is rated for only 8A continuous drain current, compared to the original 14A rating. Substitution is valid only for applications with current requirements not exceeding 8A. The 700V voltage rating provides additional margin above the original 600V specification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification, matching the regulatory status of the original STP16NK60Z.

Q: What is gate charge (Qg) and why does it vary among substitutes?

A: Gate charge represents the total charge required to switch the MOSFET from off to on state. Lower gate charge values reduce switching losses and gate drive circuit complexity. Variations among substitutes reflect different semiconductor process technologies and internal designs. Gate charge differences do not prevent substitution but influence circuit performance.

Q: Is IXKC20N60C a direct replacement for STP16NK60Z?

A: IXKC20N60C provides 600V voltage rating and 15A continuous drain current, exceeding the original 14A specification. However, it uses ISOPLUS220™ packaging instead of standard TO-220-3. Electrical compatibility is confirmed, but mechanical PCB layout changes are required for package substitution.
