Key Parameters

Substitute Part Grouping Explanation

Substitution of the RFP15N05L is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• FET Type: N-Channel
• Drain to Source Voltage (Vdss): 50V
• Current - Continuous Drain (Id) @ 25°C: 15A (Tc)
• Package / Case: TO-220-3 or compatible TO-220 variant
• Mounting Type: Through Hole

The IRFZ20PBF meets these core substitution criteria. Both devices share identical Vdss (50V) and Id (15A) ratings, operate within the same temperature range (-55°C to 150°C), and use compatible Through Hole TO-220 packaging. The IRFZ20PBF is classified as Active product status, providing ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The IRFZ20PBF is a direct substitute for the RFP15N05L based on electrical and mechanical compatibility. Both devices are rated for 50V Vdss and 15A continuous drain current, with identical operating temperature ranges and Through Hole TO-220 packaging.

The IRFZ20PBF offers the advantage of Active product status, ensuring continued availability and manufacturing support. The device carries ROHS3 compliance certification, meeting current environmental and regulatory standards. Both parts maintain REACH Unaffected status and EAR99 export classification.

The IRFZ20PBF exhibits lower on-resistance (100 mOhm @ 10A, 10V versus 140 mOhm @ 15A, 5V) and higher maximum gate voltage rating (±20V versus ±10V), providing enhanced performance margins in switching applications. Power dissipation rating of 40W (Tc) on the IRFZ20PBF is lower than the RFP15N05L specification of 60W (Tc); thermal design verification is required for applications operating at maximum power levels.

Frequently Asked Questions (FAQ)

Q: Can the IRFZ20PBF directly replace the RFP15N05L in existing designs?

A: Yes. Both devices share identical Vdss (50V) and Id (15A) ratings, operate within the same temperature range (-55°C to 150°C), and use compatible Through Hole TO-220 packaging. Pinout compatibility exists between TO-220-3 and TO-220AB variants. Thermal design review is recommended for applications operating near maximum power dissipation limits due to the lower 40W rating of the IRFZ20PBF.

Q: What are the key electrical differences between these parts?

A: The IRFZ20PBF exhibits lower on-resistance (100 mOhm @ 10A, 10V) compared to the RFP15N05L (140 mOhm @ 15A, 5V), resulting in reduced conduction losses. The IRFZ20PBF supports higher maximum gate voltage (±20V versus ±10V). Input capacitance values are similar (850 pF versus 900 pF @ 25V). The RFP15N05L specifies higher power dissipation capability (60W versus 40W).

Q: Are there packaging compatibility concerns?

A: Both devices use Through Hole TO-220 packaging. The RFP15N05L is specified as TO-220-3, while the IRFZ20PBF is supplied in TO-220AB variant. These packages are mechanically and electrically compatible for standard PCB mounting applications. Verify footprint dimensions with component datasheets for specific board layouts.

Q: What is the product availability status of each part?

A: The RFP15N05L is classified as Obsolete, with 4260 pieces currently in stock. The IRFZ20PBF is classified as Active, with 15126 pieces in stock, ensuring long-term procurement availability and manufacturing support.

Q: Are there regulatory or compliance differences?

A: The IRFZ20PBF carries ROHS3 compliance certification. Both parts maintain REACH Unaffected status and EAR99 export classification. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for both devices. Design compliance requirements should be verified against specific application standards.
