| FFF Compatibility | The SOT-323 package shares a similar footprint and the exact same pinout (Pin 1: Gate, Pin 2: Source, Pin 3: Drain), but minor package and pad dimension differences from the original MCPH3/SC-70FL require engineering review.Both parts are ultra-compact 3-pin surface-mount devices with similar profile and outline.The gate-source voltage limit is lower (±8V max vs ±12V max) and the maximum power dissipation is lower (395mW vs 800mW), which may affect thermal performance in high-power applications. | Shares the identical pin assignments (Pin 1: Gate, Pin 2: Source, Pin 3: Drain) but the standard SOT-323 package footprint has slight dimensional variances from the proprietary MCPH3 shape.Both use a compact 3-pin surface-mount package.While current, voltage, and Rds(on) specs are superior, the power dissipation is capped at 500mW compared to the original's 800mW rating. | ||
 AI Summary | MCH3476-TL-H by onsemi: N-Channel 20 V 2A (Ta) 800mW (Ta) Surface Mount SC-70FL/MCPH3. | This is the official distributor-recommended alternative with a highly compatible SOT-323 footprint. It offers a lower Rds(on) of 65 mOhm and an active lifecycle status, although it has a lower power dissipation ceiling and a reduced gate-source voltage rating.
| This is a high-performance active alternative that matches the original's ±12V Vgs rating and substantially increases the continuous drain current capability to 3.5A. It features a highly efficient 42 mOhm on-resistance, though it trades off some maximum power dissipation capability.

Frequently asked questions
Yes. The onsemi MCH3476-TL-H is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the onsemi MCH3476-TL-H are the PMF63UNEX (Nexperia USA Inc.) and the DMN2058UW-13 (Diodes Incorporated), out of 4 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the MCH3476-TL-H are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The MCH3476-TL-H (onsemi) is a part in the Transistors category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
