PROD
A functional alternative from the same series with a higher current rating but significantly different inductance.
Reviewing alternatives for the PROD PDUUAT98-203MLN, a 20mH, 600mA common mode choke. While no direct drop-in replacements are identified, several parts from the same series offer the same package but require careful review of their different inductance values.
Inductance mismatch will change filtering characteristics.
Candidates are from the same series and share the same package style.
Availability of specific family members may vary.
Direct replacement for PDUUAT98-203MLN should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Select a part from the PDUUAT98 series with an inductance that meets your application's EMI filtering needs. Verify pinout from the datasheet.
The primary risk is altered circuit performance due to incorrect inductance, which impacts EMI filtering effectiveness.
