IXTY32P05T P-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IXTY32P05T is an active P-Channel MOSFET manufactured by IXYS, designed for surface mount applications in the TO-252AA package. This device operates at 50V drain-to-source voltage with a continuous drain current rating of 32A at 25°C, delivering 83W maximum power dissipation. The part is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1) and is currently in active production with 21,200 units in stock.

Equivalent and substitute parts are identified when design requirements permit operation at reduced voltage ratings, lower current specifications, or when alternative packaging within the same mechanical footprint is acceptable. Substitution is necessary when primary part availability is limited, when cost optimization is required, or when thermal and electrical performance margins allow for lower-rated alternatives.

Substitute Part Grouping Explanation

Substitution of the IXTY32P05T is determined by the following electrical and mechanical criteria:

Primary Substitution Criteria:

FET Type: P-Channel topology required
Package: TO-252-3 (DPAK) mechanical compatibility
Drain-to-Source Voltage (Vdss): Minimum 50V for direct substitution; lower voltage ratings acceptable only when circuit design permits
Continuous Drain Current (Id): Minimum 32A for direct substitution; lower current ratings acceptable when thermal and load requirements permit
On-Resistance (Rds On): Lower or equivalent values maintain performance; higher values increase power dissipation
Operating Temperature: Minimum -55°C to 150°C range
Compliance: RoHS3 and REACH status alignment

Substitution Logic: Parts are grouped as equivalent when they maintain the 50V/32A specification envelope. Parts are grouped as acceptable substitutes when voltage or current ratings are reduced but remain within acceptable design margins for specific applications. All substitute parts listed share the P-Channel MOSFET topology, TO-252-3 package footprint, and RoHS3 compliance status.

Engineering Selection Recommendations

Direct Equivalent (Same Electrical Envelope): No substitute parts maintain the full 50V/32A specification of the IXTY32P05T. All listed alternatives operate at reduced voltage or current ratings.

Acceptable Substitutes (Reduced Voltage Rating):

RSD160P05TL (Rohm Semiconductor) operates at 45V drain-to-source voltage with 16A continuous drain current. This part is suitable for applications where the circuit voltage does not exceed 45V and current requirements do not exceed 16A. The 50mOhm on-resistance at 10V is comparable to the main part. RoHS3 compliance and unlimited MSL rating align with the IXTY32P05T. Inventory availability is 3,730 units.

Acceptable Substitutes (Reduced Current Rating):

TJ15P04M3,RQ(S (Toshiba) operates at 40V with 15A continuous drain current. This part delivers 36mOhm on-resistance at 10V, which is superior to the main part. The device is suitable for applications requiring 40V operation with current demands up to 15A. RoHS3 compliance and 150°C maximum junction temperature match the IXTY32P05T. Inventory availability is 3,475 units.

TJ10S04M3L(T6L1,NQ (Toshiba) operates at 40V with 10A continuous drain current. This part is suitable for lower-current applications at 40V. The 44mOhm on-resistance and 27W power dissipation provide adequate performance for reduced-load scenarios. Operating temperature extends to 175°C. RoHS3 compliance is confirmed. Inventory availability is 3,000 units.

DMP4047SK3-13 (Diodes Incorporated) operates at 40V with 20A continuous drain current. This part is suitable for 40V applications with current requirements up to 20A. The 45mOhm on-resistance is comparable to the main part. However, power dissipation is limited to 1.6W (Ta), which is significantly lower than the IXTY32P05T. RoHS3 compliance is confirmed. Inventory availability is 30,600 units.

Selection Basis: All substitute parts are active products with RoHS3 compliance and REACH unaffected status. Selection depends on circuit voltage and current requirements. Parts with lower voltage ratings require verification that the application circuit does not exceed the specified Vdss. Parts with lower current ratings require confirmation that load current does not exceed the specified Id rating.

Frequently Asked Questions (FAQ)

Q: Can the DMP4047SK3-13 replace the IXTY32P05T in all applications?

A: No. The DMP4047SK3-13 operates at 40V maximum drain-to-source voltage compared to the IXTY32P05T's 50V rating. Substitution is only valid when the circuit voltage does not exceed 40V. Additionally, the continuous drain current is limited to 20A versus 32A, and power dissipation is 1.6W versus 83W. Substitution requires verification that both voltage and current requirements are within the DMP4047SK3-13 specifications.

Q: What is the primary difference between the RSD160P05TL and the IXTY32P05T?

A: The RSD160P05TL operates at 45V drain-to-source voltage with 16A continuous drain current, compared to the IXTY32P05T's 50V/32A rating. The RSD160P05TL is suitable for applications where circuit voltage does not exceed 45V and current does not exceed 16A. Both parts share the TO-252-3 package and RoHS3 compliance.

Q: Are all substitute parts available in the same package as the IXTY32P05T?

A: Yes. All listed substitute parts use the TO-252-3 (DPAK) package, which provides mechanical and pin compatibility with the IXTY32P05T. Packaging format differs: the IXTY32P05T is supplied in Tube, while substitutes are supplied in Cut Tape (CT) & Digi-Reel® or Tape & Reel (TR) formats.

Q: Which substitute part has the lowest on-resistance?

A: The TJ15P04M3,RQ(S has the lowest on-resistance at 36mOhm @ 7.5A, 10V. This part is suitable for applications operating at 40V with current requirements up to 15A where minimized conduction losses are beneficial.

Q: Can I use a substitute part rated for lower voltage in a 50V circuit?

A: No. Using a part with a lower Vdss rating in a circuit exceeding that voltage will result in device failure. The drain-to-source voltage must not exceed the part's maximum Vdss specification under any operating condition.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification and REACH unaffected status, matching the IXTY32P05T's regulatory compliance.

Q: What is the difference between the two Toshiba parts (TJ10S04M3L and TJ15P04M3,RQ(S)?

A: The TJ10S04M3L operates at 40V with 10A continuous drain current and extends to 175°C maximum junction temperature. The TJ15P04M3,RQ(S operates at 40V with 15A continuous drain current and is rated to 150°C maximum junction temperature. The TJ15P04M3,RQ(S delivers lower on-resistance (36mOhm versus 44mOhm) and higher power dissipation capability (29W versus 27W).

Q: Which substitute part has the highest inventory availability?

A: The DMP4047SK3-13 from Diodes Incorporated has the highest inventory availability at 30,600 units in stock, compared to 3,730 units for the RSD160P05TL and 3,475 units for the TJ15P04M3,RQ(S.
