IRF9Z14 P-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IRF9Z14 is a P-Channel Metal Oxide Semiconductor Field Effect Transistor (MOSFET) manufactured by Vishay Siliconix, rated for 60V drain-to-source voltage with 6.7A continuous drain current at 25°C. The device is packaged in a TO-220AB through-hole configuration and dissipates up to 43W at the case temperature. The IRF9Z14 is classified as obsolete, necessitating identification of active equivalent and substitute parts for new designs and ongoing production requirements. Equivalent parts maintain identical electrical and mechanical specifications while offering improved availability and compliance status.

• On-State Drain Resistance (Rds On): 500 mOhm @ 4A, 10V
• Gate Threshold Voltage (Vgs(th)): 4V @ 250µA
• Gate Charge (Qg): 12 nC @ 10V
• Maximum Gate-Source Voltage (Vgs): ±20V
• Input Capacitance (Ciss): 270 pF @ 25V
• Power Dissipation: 43W (Tc)
• Operating Temperature Range: -55°C to 175°C (TJ)

Mechanical Parameters (Critical for Substitution):

• Package Type: TO-220-3 (TO-220AB)
• Mounting Type: Through Hole
• FET Technology: Metal Oxide Semiconductor (MOSFET)
• Channel Type: P-Channel

All substitute parts listed maintain identical values across these parameters, ensuring direct functional and mechanical compatibility in circuit applications.

Engineering Selection Recommendations

IRF9Z14PBF is the direct equivalent substitute for the obsolete IRF9Z14. This part maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. The PBF suffix indicates lead-free plating, aligning with modern manufacturing and environmental standards. This part is the primary selection for new designs and production transitions from the IRF9Z14.

IRF9Z10 and IRF9Z10PBF are parametric equivalents that maintain all critical electrical specifications and mechanical compatibility. Both parts are active products from Vishay Siliconix. The IRF9Z10PBF variant provides ROHS3 compliance, making it suitable for applications requiring environmental certification. These parts are interchangeable with the IRF9Z14 in circuit applications where the specified electrical and thermal parameters are required.

Selection between active substitutes should be based on compliance requirements and packaging preferences. For new production requiring RoHS compliance, IRF9Z14PBF or IRF9Z10PBF are appropriate selections. For applications without compliance mandates, all three active parts (IRF9Z14PBF, IRF9Z10, IRF9Z10PBF) provide equivalent functionality.

Frequently Asked Questions (FAQ)

Q: Can IRF9Z14PBF be used as a direct replacement for IRF9Z14?

A: Yes. IRF9Z14PBF is a direct equivalent with identical electrical and mechanical specifications. The primary difference is product status (active versus obsolete) and RoHS compliance. Both parts are pin-compatible and functionally equivalent in all circuit applications.

Q: What is the difference between IRF9Z14 and IRF9Z10?

A: Both parts share identical electrical specifications including Vdss (60V), Id (6.7A), Rds On (500 mOhm), and all other critical parameters. Both use the same TO-220AB package. The parts are parametric equivalents suitable for direct substitution.

Q: Are IRF9Z10 and IRF9Z10PBF interchangeable?

A: Yes. These parts are electrically and mechanically identical. The PBF suffix indicates lead-free plating and ROHS3 compliance. Selection between them depends on compliance requirements and supplier availability.

Q: Does the TO-220AB package differ between substitute parts?

A: No. All listed parts use the TO-220-3 package designation with TO-220AB supplier device package. Pin configuration, lead spacing, and mounting requirements are identical across all substitutes.

Q: What is the significance of the PBF suffix?

A: The PBF suffix indicates lead-free plating and ROHS3 compliance. Parts with this designation meet environmental and manufacturing standards for lead-free soldering processes. Parts without this suffix may contain lead and may not meet certain regulatory requirements.

Q: Can these parts be used in applications requiring RoHS compliance?

A: IRF9Z14PBF and IRF9Z10PBF are ROHS3 compliant and suitable for applications with RoHS requirements. IRF9Z14 and IRF9Z10 are non-compliant and should not be used in applications requiring RoHS certification.

Q: Are all substitute parts available in the same packaging options?

A: IRF9Z14PBF, IRF9Z10, and IRF9Z10PBF are supplied in Tube packaging. The original IRF9Z14 packaging is not specified in the provided data. All parts maintain the same TO-220AB device package for circuit board mounting.

Q: What is the operating temperature range for these parts?

A: All listed parts operate across -55°C to 175°C junction temperature (TJ), providing identical thermal performance and operating range.

Q: Are there any electrical parameter differences between the substitute parts?

A: No. All substitute parts maintain identical values for Vdss, Id, Rds On, Vgs(th), gate charge, input capacitance, power dissipation, and all other specified electrical parameters.
