Parameter Comparison

Engineering Selection Recommendations

The IRFR9110PBF is a direct parametric equivalent to the IRFR9110. All electrical and mechanical specifications are identical across voltage ratings, current ratings, on-resistance, gate charge, capacitance, and thermal characteristics.

Product Status Consideration: The IRFR9110 is classified as Obsolete, while the IRFR9110PBF is Active. For new designs and ongoing production support, the IRFR9110PBF is the appropriate selection to ensure long-term component availability and manufacturer support.

Compliance Consideration: The IRFR9110PBF carries ROHS3 Compliant certification, whereas the IRFR9110 is RoHS non-compliant. Applications subject to RoHS directives or requiring RoHS-compliant component documentation must use the IRFR9110PBF.

Packaging Consideration: The IRFR9110PBF is supplied in Tube packaging, while the original IRFR9110 packaging specification is not detailed. Both parts use the identical DPAK surface mount package format (TO-252-3, SC-63).

Frequently Asked Questions (FAQ)

Q: Can the IRFR9110PBF be used as a direct replacement for the IRFR9110?

A: Yes. The IRFR9110PBF is a parametric equivalent with identical electrical specifications and mechanical packaging. All voltage, current, on-resistance, gate charge, and thermal parameters match exactly. The parts are pin-compatible and functionally interchangeable in circuit applications.

Q: What is the difference between the IRFR9110 and IRFR9110PBF?

A: The primary differences are product status and compliance certification. The IRFR9110 is Obsolete and RoHS non-compliant. The IRFR9110PBF is Active and ROHS3 Compliant. Electrical and mechanical specifications are identical.

Q: Why should I use the IRFR9110PBF instead of the IRFR9110?

A: The IRFR9110PBF is recommended for new designs and ongoing production because it carries Active product status, ensuring continued manufacturer support and availability. Additionally, ROHS3 compliance is required for applications subject to RoHS directives.

Q: Are there any circuit design changes required when substituting the IRFR9110PBF for the IRFR9110?

A: No circuit design changes are required. The IRFR9110PBF maintains identical electrical characteristics, including Vdss (100V), Id (3.1A), Rds On (1.2Ω @ 1.9A, 10V), and all other parameters. The parts are functionally equivalent.

Q: What is the DPAK package, and is it the same for both parts?

A: DPAK is a Surface Mount package designation (TO-252-3, also known as SC-63) with two leads plus a tab for thermal connection. Both the IRFR9110 and IRFR9110PBF use this identical package format, ensuring mechanical compatibility on printed circuit boards.

Q: Can the IRFR9110PBF handle the same power dissipation as the IRFR9110?

A: Yes. Both parts have identical power dissipation ratings of 2.5W (Ta) and 25W (Tc), with the same operating temperature range of -55°C to 150°C (TJ).

Q: Is the IRFR9110PBF available in the same quantities as the IRFR9110?

A: Inventory levels differ. The IRFR9110 has 10,200 pieces in stock, while the IRFR9110PBF has 9,400 pieces in stock. Both are available as new original components.
