Frequently Asked Questions (FAQ)

Q1: What are the key parameters to check when selecting substitutes for the CMS25N03V8-HF?
A1: Key parameters include FET type, technology, voltage and current ratings, Rds(on), threshold voltage, gate charge, input capacitance, power dissipation, operating temperature, mounting type, and package form factor.

Q2: Is the package of the substitute CMS25N03V8A-HF compatible with the obsolete CMS25N03V8-HF?
A2: Both parts are supplied in 8-lead PDFN packages. The mounting style is surface mount, with similar outline and device package classifications as specified.

Q3: Are there any compliance or regulatory differences between the parts?
A3: Both the main and substitute parts are ROHS3 compliant, classified as ECCN EAR99, and listed under HTSUS 8541.29.0095. Moisture Sensitivity Level is 1 for each.

Q4: Does the substitute part have an equivalent current and voltage capability?
A4: Both the main and substitute parts are rated for 30V drain-to-source voltage and 25A continuous drain current at Tc.

Q5: Are there performance differences in Rds(on) or gate charge values between the two parts?
A5: Rds(on) values are consistent at 18mOhm, though specified at different current conditions (10A for the main part, 12A for the substitute). Gate charge varies slightly, with the substitute part at 8 nC versus 7.2 nC in the original. Input capacitance also has minor variation. All values are as provided in the data.
