IRLZ24L N-Channel MOSFET 60V 17A Equivalent & Substitute Parts

Part Overview

The IRLZ24L is an N-Channel MOSFET manufactured by Vishay Siliconix, rated for 60V drain-to-source voltage with 17A continuous drain current in a TO-262-3 through-hole package. This device is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design support and procurement continuity. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives with acceptable parameter variations within the same application category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRLZ24L is determined by the following critical parameters: N-Channel FET type, 60V Vdss rating, continuous drain current capability, Rds On characteristics, gate threshold voltage, operating temperature range, and through-hole mounting compatibility. Substitute parts are grouped into two categories based on package configuration and electrical performance alignment.

Parametric Equivalent (Same Package): IRLZ24LPBF maintains identical electrical specifications and TO-262-3 package configuration, differing only in product status (Active vs. Obsolete) and RoHS compliance level.

Functional Substitutes (Alternative Packages): FQP13N06L and STP16NF06 provide equivalent voltage and temperature ratings with comparable drain current and Rds On performance, but utilize alternative through-hole packages (TO-220-3) with higher power dissipation ratings. These substitutes accommodate applications where package footprint flexibility is acceptable.

Parameter Comparison

Engineering Selection Recommendations

IRLZ24LPBF is the primary equivalent substitute for the obsolete IRLZ24L. This part maintains identical electrical specifications and TO-262-3 package configuration while offering Active product status and ROHS3 compliance. Selection of IRLZ24LPBF is appropriate for direct replacement in existing designs without circuit modification.

FQP13N06L and STP16NF06 serve as functional substitutes where package footprint changes are acceptable. Both devices provide 60V Vdss rating and operating temperature range matching the IRLZ24L. FQP13N06L delivers 13.6A continuous drain current with 45W power dissipation in TO-220-3 package. STP16NF06 delivers 16A continuous drain current with 45W power dissipation in TO-220-3 package and carries ROHS3 compliance certification. These alternatives are suitable for applications where the higher power dissipation capability and alternative package geometry accommodate thermal and layout requirements.

Selection between FQP13N06L and STP16NF06 depends on continuous current requirements and compliance certifications. STP16NF06 provides higher drain current (16A vs. 13.6A) and documented ROHS3 compliance, making it the preferred functional substitute where package transition is feasible.

Frequently Asked Questions (FAQ)

Q: Can IRLZ24LPBF be used as a direct replacement for IRLZ24L?

A: Yes. IRLZ24LPBF is a parametric equivalent with identical electrical specifications (60V Vdss, 17A Id, 100 mOhm Rds On, 2V Vgs(th)) and matching TO-262-3 package configuration. The primary differences are product status (Active vs. Obsolete) and RoHS compliance level (ROHS3 vs. Non-compliant). No circuit modifications are required.

Q: What are the key differences between IRLZ24L and the TO-220-3 package substitutes?

A: FQP13N06L and STP16NF06 utilize TO-220-3 packages instead of TO-262-3, resulting in different physical footprints and lead configurations. Both maintain 60V Vdss and -55 to 175°C operating temperature range. Drain current ratings differ: FQP13N06L provides 13.6A and STP16NF06 provides 16A, compared to IRLZ24L's 17A. Power dissipation ratings increase to 45W (Tc) for both TO-220-3 devices versus 60W (Tc) for IRLZ24L. Gate threshold voltage and input capacitance characteristics also vary.

Q: Are there RoHS compliance considerations for substitute selection?

A: IRLZ24L is RoHS non-compliant. IRLZ24LPBF and STP16NF06 are ROHS3 compliant. FQP13N06L RoHS status is not specified in available documentation. For applications requiring RoHS compliance certification, IRLZ24LPBF or STP16NF06 are appropriate selections.

Q: How do gate charge and input capacitance differences affect circuit design?

A: IRLZ24L and IRLZ24LPBF both exhibit 18 nC gate charge at 5V and 870 pF input capacitance at 25V. FQP13N06L and STP16NF06 show reduced gate charge (6.4 nC and 13 nC respectively) and input capacitance (350 pF and 315 pF respectively). Lower gate charge and capacitance values reduce driver circuit power requirements and enable faster switching transitions. These differences may require gate driver circuit adjustments when transitioning to TO-220-3 package alternatives.

Q: What inventory considerations apply to these substitutes?

A: IRLZ24L has 1156 pieces in stock (Obsolete status). IRLZ24LPBF has 1300 pieces available (Active status). FQP13N06L has 22488 pieces in stock. STP16NF06 has 37100 pieces in stock. For long-term procurement continuity, IRLZ24LPBF, FQP13N06L, or STP16NF06 are preferred due to Active product status and higher inventory levels.
