FDMC86265P P-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The FDMC86265P is a P-Channel MOSFET manufactured by onsemi, rated for 150V drain-to-source voltage with 1A continuous drain current (Ta) and 1.8A (Tc). This device is part of the PowerTrench® series and is housed in an 8-MLP (3.3x3.3) surface mount package. The FDMC86265P is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility across voltage ratings, current handling, thermal characteristics, and package specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FDMC86265P are selected based on strict electrical and mechanical compatibility criteria. The primary substitution logic is based on the following parameters:

Channel Type & Voltage Rating: All substitutes must be P-Channel MOSFETs with a Vdss rating of 150V or greater to maintain voltage compatibility.

Package Compatibility: All substitutes must use the 8-MLP (3.3x3.3) surface mount package to ensure direct PCB layout compatibility without redesign.

Current Handling: Substitute parts must support continuous drain current ratings equal to or exceeding the FDMC86265P specification (1A Ta / 1.8A Tc). Higher current ratings provide design margin and thermal performance improvement.

On-Resistance (Rds On): Substitute parts must maintain Rds On values at or below the original specification to preserve circuit performance and minimize power dissipation.

Gate Charge & Capacitance: Substitute parts with lower gate charge and input capacitance values reduce switching losses and improve circuit efficiency.

Compliance & Status: All substitutes must maintain RoHS3 compliance, MSL Level 1 rating, and REACH unaffected status to meet regulatory and supply chain requirements.

The FDMC2523P meets all substitution criteria and is classified as an active product with superior current handling and thermal performance characteristics.

Engineering Selection Recommendations

FDMC2523P as Primary Substitute

The FDMC2523P is the manufacturer-recommended substitute for the obsolete FDMC86265P. Both devices are manufactured by onsemi and share identical voltage ratings (150V Vdss), package specifications (8-PowerWDFN 3.3x3.3), and operating temperature ranges (-55°C to 150°C).

The FDMC2523P is classified as an active product with full production support and availability, eliminating supply chain risk associated with the obsolete FDMC86265P. The substitute provides enhanced current handling capability (3A Tc versus 1.8A Tc) and significantly improved thermal performance (42W Tc versus 16W Tc), enabling operation in higher power applications.

Both devices maintain identical regulatory compliance: ROHS3 certification, MSL Level 1 (unlimited moisture sensitivity), and REACH unaffected status. This ensures substitution does not introduce compliance or supply chain complications.

The FDMC2523P is suitable for direct replacement in existing designs without PCB layout modifications, as the 8-MLP package footprint is identical. The higher current and power ratings provide design margin for thermal and electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the FDMC2523P be used as a direct replacement for the FDMC86265P?

A: Yes. Both devices share identical package specifications (8-PowerWDFN 3.3x3.3), voltage ratings (150V Vdss), and operating temperature ranges (-55°C to 150°C). The FDMC2523P provides higher current and power handling, making it suitable for direct PCB substitution without layout redesign.

Q: What are the key differences between the FDMC86265P and FDMC2523P?

A: The FDMC2523P provides superior performance in three areas: continuous drain current (3A Tc versus 1.8A Tc), power dissipation capability (42W Tc versus 16W Tc), and maximum gate voltage (±30V versus ±25V). The FDMC86265P has lower gate charge (4 nC versus 9 nC) and lower input capacitance (210 pF versus 270 pF). The FDMC2523P is an active product; the FDMC86265P is obsolete.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both devices are ROHS3 compliant, carry MSL Level 1 (unlimited) ratings, and are REACH unaffected. Substitution introduces no regulatory or compliance complications.

Q: Will the FDMC2523P affect circuit performance compared to the FDMC86265P?

A: The FDMC2523P has higher gate charge (9 nC versus 4 nC) and input capacitance (270 pF versus 210 pF), which may increase switching losses slightly in high-frequency applications. However, the lower on-resistance at higher current levels (1.5 Ohm @ 1.5A, 10V) and superior thermal performance provide overall circuit benefits in most applications.

Q: Is the FDMC2523P available in the same packaging as the FDMC86265P?

A: Yes. Both devices use the 8-MLP (3.3x3.3) surface mount package, designated as 8-PowerWDFN. No PCB layout modifications are required for substitution.

Q: What is the product status of the FDMC2523P?

A: The FDMC2523P is classified as an active product with full manufacturing and supply support. The FDMC86265P is obsolete and no longer in production.

Q: Can the FDMC2523P handle higher current applications than the FDMC86265P?

A: Yes. The FDMC2523P is rated for 3A continuous drain current (Tc) compared to 1.8A (Tc) for the FDMC86265P, and supports 42W power dissipation versus 16W. This enables use in higher power switching applications.
