FFF CompatibilityBoth components share the exact same 16-pin SOIC package and an identical pinout layout, mapping every pin function like QCAP, PUMP, and 5VSTBY to the same positions.Both parts are packaged in a standard 16-pin SOIC (3.90mm width) package with identical physical dimensions and footprint.The FAN5067M is an ACPI dual switch controller that fully matches or exceeds the voltage, current, and timing specifications of the FAN5063M, with the added capability to select 3.3V or 5V dual output.The pin assignment is completely different (e.g., GND is on Pin 8 instead of Pin 11), meaning it cannot be dropped onto the same PCB footprint without a board redesign.Both parts share the standard 16-pin SOIC (3.90mm body width) form factor and mounting style.Functionally similar ACPI controller managing 3.3V, 5V, and memory rails with built-in soft-start and fault protection schemes.
AI Summary

FAN5063M by onsemi: PMIC - Voltage Regulators - Linear Switching 4 Output Step-Down (Buck) (1), Linear (LDO) (1) 250kHz 16-SOIC.

The onsemi FAN5067M is a direct, pin-compatible sibling from the same manufacturer family. It features the exact same pinout and physical package while offering slightly more versatility by supporting both 3.3V and 5V dual-rail configurations through feedback adjustments.

  • Direct pin-to-pin drop-in replacement with identical 16-pin SOIC pinout.
  • Identical control logic inputs (PWROK, SLP_S3, and SLP_S5) and state transitions.
  • Slightly more versatile design allowing either 3.3V or 5V dual-rail feedback configuration.
  • The component is marked as obsolete by the manufacturer and is primarily available through legacy stockists such as Rochester Electronics.

The HIP6501ACBZ is a high-quality ACPI power controller alternative housed in a 16-pin SOIC. While it handles similar power planes and motherboard transition states, it is pin-incompatible and will require a full board layout redesign.

  • Highly reliable, active alternative from Intersil/Renesas designed for similar ACPI motherboard voltage regulation applications.
  • Integrates control for 3.3VDUAL, 5VDUAL, and selectable 2.5V/3.3V memory voltage planes in a single IC.
  • Completely different pinout requires a PCB redesign.
  • Memory voltage setting is configured at startup (multiplexed on the FAULT pin) rather than continuously adjusted through feedback pins like VADJFB.

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
