IRFR010 Equivalent & Substitute Parts

Part Overview

The IRFR010 is an N-Channel MOSFET manufactured by Vishay Siliconix, rated for 50V drain-to-source voltage with 8.2A continuous drain current at 25°C. The device is housed in a DPAK (TO-252-3) surface mount package and dissipates up to 25W. The IRFR010 is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. Substitute parts must maintain identical electrical performance and mechanical compatibility while offering current availability and compliance status.

Engineering Selection Recommendations

The IRFR010PBF is the direct parametric equivalent for the obsolete IRFR010. All electrical specifications, including voltage rating, current capacity, on-state resistance, and thermal characteristics, are identical. Both devices utilize the same DPAK surface mount package with identical pinout and mechanical footprint, enabling direct board-level substitution without layout modification.

The IRFR010PBF offers two significant advantages over the original IRFR010:

Product Status: The IRFR010PBF maintains active manufacturing status with established supply chain availability (15,933 pieces in stock versus 2,000 pieces for the obsolete variant). This ensures long-term procurement reliability for production and design continuation.

Compliance Profile: The IRFR010PBF is ROHS3 compliant, whereas the IRFR010 is RoHS non-compliant. Both devices maintain REACH Unaffected status and EAR99 export classification. The improved compliance status of the IRFR010PBF aligns with current regulatory requirements for electronic component procurement in regulated industries.

For new designs and ongoing production, the IRFR010PBF is the appropriate selection. For legacy systems currently using the IRFR010, direct substitution is electrically and mechanically valid.
