SUMMARY

The discussion focuses on replacing the IRF3205 MOSFET for a 3D printer, which is now obsolete. Participants confirm that any IRF3205 variant should work, as the additional codes are lot/date identifiers. Recommendations include using the manufacturer's selector guide to find a suitable replacement with matching voltage and current ratings. A specific alternative, the IRF3205PBF, was identified as having similar characteristics and is available for purchase.

PREREQUISITES
  • Understanding of N-channel MOSFETs
  • Familiarity with electronic component specifications
  • Knowledge of power dissipation in MOSFETs
  • Experience with sourcing electronic components online
NEXT STEPS
  • Research the manufacturer's selector guide for MOSFETs
  • Learn about alternative MOSFETs with similar voltage and current ratings
  • Explore the specifications of the IRF3205PBF as a replacement option
  • Investigate sourcing electronic components from suppliers like Mouser and Digi-Key
USEFUL FOR

Electronics hobbyists, 3D printer enthusiasts, and engineers involved in component replacement and sourcing for electronic devices.

I need to replace a mosfet for a 3D printer. The seller and manufacturer were contacted on this but were not able to fulfill a replacement.

See this on mosfet:
IRF3205
P705D
KCAB

Unable to find exactly this one described above. Could any IRF 3205 work?

Your thoughts?

Yes. Those other numbers and letters are lot/date codes.

Thanks for the recommendations. Just ordered a set of replacements. Thanks everyone!
 
The way to start is with manufacturer's selector guide. Look for one with same voltage and current ratings.

Are you trying to replace one or a few damaged FETs or are you replacing this on a design that you will be making in large quantity?
