FFF CompatibilityThe part number represents the same physical device in Tape & Reel packaging rather than Tube. Pinout and package are 100% identical.Same PowerSO-36 package dimensions and footprint.Identical electrical parameters, internal registers, and control features.Utilizes the exact same PowerSO-36 package with an identical pin layout, verified via pinout extraction.Identical physical dimensions and mounting style.Uses predictive current control instead of voltage-mode control, and step resolution is limited to 1/16 microstepping compared to the original 1/128. Requires firmware updates for registers and driving algorithms.
AI Summary

L6470PD by STMicroelectronics: Bipolar Motor Driver DMOS SPI PowerSO-36 Slug Up.

This is the tape-and-reel version of the same device. It is a 100% direct drop-in replacement with identical electrical and physical properties.

  • Direct sibling in identical package and footprint
  • Identical electrical specifications (3A, 8V to 45V load)
  • Identical dSPIN motion engine with 1/128 microstepping

A pin-compatible family variant that utilizes current control mode instead of voltage mode. This offers an easy PCB fallback but requires a firmware register map rewrite and limits microstepping to 1/16.

  • 100% pin-compatible layout in the same PowerSO-36 package
  • Same 3A output current and 8V to 45V load voltage ratings
  • Fully integrated power stage and SPI control interface
  • Limits microstepping resolution to 1/16 (versus 1/128 in L6470)
  • Uses predictive current control instead of voltage-mode control, requiring firmware changes

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.
