Substitute Part Grouping Explanation

Substitution of the IXFV15N100PS is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

Drain-to-Source Voltage (Vdss): Minimum 1000 V
Continuous Drain Current (Id): Minimum 15 A at 25°C
Gate Drive Voltage: 10 V
Operating Temperature Range: -55°C to 150°C
FET Technology: N-Channel MOSFET

Secondary Compatibility Factors:

On-state resistance (Rds On) at specified conditions
Gate charge (Qg) characteristics
Input capacitance (Ciss)
Mounting configuration (surface mount or through-hole with appropriate footprint adaptation)

The substitute parts identified below meet the primary electrical criteria. However, mounting type differences exist: the IXFV15N100PS uses surface mount PLUS-220SMD packaging, while the identified substitutes employ through-hole TO-247 and TO-220 packages. This distinction requires circuit board redesign or adapter solutions for direct replacement.

Engineering Selection Recommendations

APT14F100B (Microchip Technology)

The APT14F100B is the closest electrical equivalent to the IXFV15N100PS. Both devices share identical 1000 V Vdss rating and 10 V drive voltage specification. The APT14F100B delivers 14 A continuous drain current, which is 1 A lower than the original part but remains within acceptable tolerance for most high-voltage switching applications. The device is currently in active production status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment. The primary design consideration is the transition from surface mount PLUS-220SMD to through-hole TO-247-3 packaging, which requires circuit board layout modification.

STP13N95K3 (STMicroelectronics)

The STP13N95K3 provides an alternative solution with 950 V Vdss rating and 10 A continuous drain current. This device operates within the same temperature range and shares the 10 V drive voltage specification. The lower voltage and current ratings result in reduced power dissipation (190 W versus 543 W), making this substitute suitable for applications where the original part's full performance envelope is not required. The STP13N95K3 is in active production with ROHS3 compliance. Like the APT14F100B, this part requires packaging conversion from surface mount to through-hole TO-220-3 configuration.

Product Status Consideration

Both substitute parts are classified as active products with current manufacturing support, providing superior long-term availability compared to the obsolete IXFV15N100PS. Selection between APT14F100B and STP13N95K3 depends on application current and voltage requirements relative to the original 15 A, 1000 V specification.

Frequently Asked Questions (FAQ)

Q: Can the APT14F100B directly replace the IXFV15N100PS without circuit modification?

A: The APT14F100B meets the primary electrical specifications (1000 V Vdss, 10 V drive voltage, -55°C to 150°C operating range) but requires circuit board redesign due to packaging differences. The IXFV15N100PS uses surface mount PLUS-220SMD packaging, while the APT14F100B employs through-hole TO-247-3 packaging. Direct socket replacement is not possible without adapter hardware or board layout revision.

Q: What is the significance of the 1 A current difference between the IXFV15N100PS (15 A) and APT14F100B (14 A)?

A: The 1 A reduction in continuous drain current represents a 6.7% decrease in current-carrying capacity. For applications operating at or near the original 15 A specification, thermal analysis and circuit validation are required to confirm the APT14F100B operates within acceptable temperature and power dissipation limits. Applications utilizing less than 14 A continuous current experience no functional impact.

Q: Why does the STP13N95K3 have lower power dissipation than the IXFV15N100PS?

A: The STP13N95K3 is rated for 10 A continuous drain current and 950 V Vdss, compared to the IXFV15N100PS specifications of 15 A and 1000 V. Lower current and voltage ratings result in reduced power dissipation (190 W versus 543 W). This device is suitable for applications where the original part's maximum performance is not required.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both the APT14F100B and STP13N95K3 carry ROHS3 compliance certification. The original IXFV15N100PS RoHS status is not specified in the provided data. Both substitutes meet current regulatory requirements for electronic component manufacturing and distribution.

Q: What packaging considerations apply when selecting a substitute?

A: The IXFV15N100PS is a surface mount device (PLUS-220SMD), while both substitutes are through-hole components (TO-247-3 and TO-220-3 respectively). Surface mount designs require board-level redesign or mechanical adapter solutions to accommodate through-hole packages. Thermal management characteristics differ between package types; through-hole packages typically offer superior heat dissipation through lead connections and mounting hardware.

Q: Can the STP13N95K3 be used in applications designed for the full 15 A, 1000 V specification?

A: The STP13N95K3 operates at reduced current (10 A) and voltage (950 V) ratings. Use in applications requiring the original 15 A, 1000 V performance envelope requires verification that the reduced specifications do not compromise circuit function, thermal management, or safety margins. Applications with design headroom below these maximum ratings may accommodate the STP13N95K3 without modification.

Q: What is the REACH compliance status of the substitute parts?

A: Both the APT14F100B and STP13N95K3 are classified as REACH Unaffected, matching the compliance status of the original IXFV15N100PS. All three devices meet international chemical substance regulations applicable to electronic components.
