RCD041N25TL Equivalent & Substitute MOSFETs Reference

Part Overview

RCD041N25TL is an N-Channel MOSFET manufactured by Rohm Semiconductor, designed for high-voltage switching applications with a Drain to Source Voltage (Vdss) of 250 V and continuous drain current (Id) of 4A (Tc). It features a maximum power dissipation of 850mW (Ta) and 29W (Tc), surface-mount CPT3 package compliant with RoHS3. The product status is "Last Time Buy," indicating limited future availability. In such cases, sourcing compatible alternatives becomes critical to maintain design continuity and procurement reliability.

Engineering Selection Recommendations

RCD041N25TL is marked as "Last Time Buy," while RD3U040CNTL1 is "Active" status. Both parts are RoHS3 compliant with MSL 1 (Unlimited) and are unaffected by REACH regulations. Compliance criteria and inventory availability support selection of RD3U040CNTL1 as an alternative in designs where continued supply and certification equivalency are required.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must be matched for substituting MOSFETs like RCD041N25TL?
A: Key required matching parameters are FET type, technology, drain to source voltage (Vdss), continuous drain current (Id), Rds On values, gate threshold voltage, maximum gate charge, maximum gate-source voltage, and input capacitance.

Q: Does the substitute RD3U040CNTL1 have package compatibility with RCD041N25TL?
A: Both parts use the TO-252-3, DPAK (2 Leads + Tab), SC-63 package, supporting direct mechanical replacement in surface-mount assemblies.

Q: Are RoHS3 and REACH compliance mandatory for substitution in regulated environments?
A: Both RCD041N25TL and RD3U040CNTL1 are ROHS3 compliant and REACH unaffected, meeting standard environmental compliance requirements for most regulated applications.

Q: Does the change in product status affect long-term availability?
