Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRFR210 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Drain-to-Source Voltage (Vdss): Must equal or exceed 200V
• FET Type: Must be N-Channel
• Technology: Must be MOSFET (Metal Oxide)
• Mounting Type: Must be Surface Mount
• Package: Must be compatible with TO-252-3 / DPAK footprint

Performance Parameters:

• Continuous Drain Current (Id): Must support minimum 2.6A at 25°C
• Rds On (Max): Must not exceed 1.5 Ohm at specified conditions
• Gate Threshold Voltage (Vgs(th)): Must be within acceptable switching range
• Operating Temperature Range: Must encompass -55°C to 150°C

Compliance Parameters:

• RoHS Status: Preferred compliance status for new designs
• Moisture Sensitivity Level (MSL): Must be rated MSL 1 or equivalent

Substitute parts identified below meet all critical matching parameters and performance specifications. Variations in secondary parameters (such as gate charge, input capacitance, or maximum gate voltage) are acceptable provided they do not degrade circuit performance or introduce incompatibility.

Engineering Selection Recommendations

IRFR210PBF (Vishay Siliconix)

The IRFR210PBF is a parametric equivalent to the IRFR210, offering identical electrical specifications and package configuration. The primary distinction is product status: IRFR210PBF carries Active status, ensuring ongoing availability and supply chain support. IRFR210PBF is ROHS3 compliant, meeting current regulatory requirements for new designs and manufacturing. This part is the direct replacement for obsolete IRFR210 applications where regulatory compliance is required.

FQD4N20TM (Fairchild Semiconductor)

The FQD4N20TM is a functional substitute rated for 200V Vdss with 3A continuous drain current, exceeding the IRFR210 specification of 2.6A. The FQD4N20TM features improved on-resistance (1.4Ω versus 1.5Ω) and lower gate charge (6.5nC versus 8.2nC), resulting in reduced switching losses and improved thermal performance. Maximum power dissipation at case temperature is 30W, compared to 25W for the IRFR210. The FQD4N20TM is housed in an identical TO-252-3 DPAK package and maintains the same operating temperature range. This part is suitable for applications where enhanced current handling and reduced switching losses provide design margin.

Selection between IRFR210PBF and FQD4N20TM depends on design requirements: IRFR210PBF for direct replacement with regulatory compliance; FQD4N20TM for applications benefiting from higher current rating and improved switching characteristics.

Frequently Asked Questions (FAQ)

Q: Can IRFR210PBF be used as a direct replacement for IRFR210?

A: Yes. IRFR210PBF is a parametric equivalent with identical electrical specifications, gate charge, input capacitance, and power dissipation ratings. Both devices are housed in the TO-252-3 DPAK package with identical pinout. The primary difference is product status and RoHS compliance. IRFR210PBF is recommended for new designs and ongoing production due to Active status and ROHS3 compliance.

Q: What are the key differences between IRFR210 and FQD4N20TM?

A: FQD4N20TM offers higher continuous drain current (3A versus 2.6A), lower on-resistance (1.4Ω versus 1.5Ω), and lower gate charge (6.5nC versus 8.2nC). Maximum case temperature power dissipation is 30W compared to 25W. Both devices share identical Vdss (200V), operating temperature range (-55°C to 150°C), and TO-252-3 DPAK package. FQD4N20TM is suitable for applications requiring enhanced current capacity or reduced switching losses.

Q: Are all three parts pin-compatible?

A: Yes. IRFR210, IRFR210PBF, and FQD4N20TM are all housed in the TO-252-3 DPAK package with identical pinout: Gate, Drain, and Source connections are in the same physical locations. Direct PCB substitution is possible without layout modification.

Q: What is the significance of RoHS compliance status?

A: IRFR210PBF is ROHS3 compliant, meeting current regulatory requirements for electronic components in many jurisdictions. IRFR210 is RoHS non-compliant, which may restrict its use in new designs or applications subject to regulatory oversight. FQD4N20TM RoHS status is not specified in available documentation. For applications requiring regulatory compliance, IRFR210PBF is the appropriate selection.

Q: Can FQD4N20TM be used in circuits designed for IRFR210?

A: Yes, with design verification. FQD4N20TM meets or exceeds all critical electrical parameters: Vdss (200V), continuous drain current (3A exceeds 2.6A requirement), and operating temperature range (-55°C to 150°C). Lower on-resistance and gate charge may improve circuit performance. However, higher input capacitance (220pF versus 140pF) may affect gate drive timing in high-frequency switching applications. Circuit simulation or bench testing is appropriate to confirm performance in specific applications.

Q: What is Moisture Sensitivity Level (MSL) and why does it matter?

A: MSL indicates the maximum time a component can be exposed to ambient moisture before soldering without risk of delamination or failure. IRFR210 and IRFR210PBF are rated MSL 1 (Unlimited), meaning they can be stored indefinitely without moisture control measures. This simplifies inventory management and reduces handling costs. FQD4N20TM MSL rating is not specified; verification with the manufacturer is recommended if moisture sensitivity is a design consideration.

Q: Which substitute part should be selected for a new design?

A: IRFR210PBF is recommended for new designs. It provides parametric equivalence to IRFR210 with Active product status, ensuring long-term availability and supply chain stability. ROHS3 compliance meets current regulatory requirements. FQD4N20TM is an alternative for applications where higher current capacity (3A), lower on-resistance, or reduced switching losses provide measurable design benefits.
