Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRF9Z14L is determined by electrical and mechanical parameter equivalence across the following critical specifications:

Electrical Parameters:

• Drain-to-source voltage rating (Vdss): 60V
• Continuous drain current (Id): 6.7A at 25°C
• On-state 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: 3.7W (Ta), 43W (Tc)
• Operating temperature range: -55°C to 175°C

Mechanical Parameters:

• Mounting type: Through Hole
• Package designation: TO-262-3 Long Leads, I2PAK, TO-262AA
• Channel type: P-Channel
• Technology: MOSFET (Metal Oxide)

Substitute parts must match all electrical parameters and maintain the same Through Hole I2PAK package configuration to ensure direct compatibility in existing circuit designs and PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

The IRF9Z14LPBF is a direct electrical and mechanical equivalent to the IRF9Z14L. All critical electrical parameters—including voltage rating, current capacity, on-state resistance, gate charge, and thermal characteristics—are identical. Both devices utilize the same Through Hole I2PAK package configuration and are manufactured by Vishay Siliconix.

The primary distinction between these parts is product lifecycle status and regulatory compliance:

IRF9Z14L: Classified as obsolete. RoHS non-compliant. Suitable for legacy system maintenance or repair where original component specifications must be preserved.

IRF9Z14LPBF: Active product status with ROHS3 compliance. Recommended for new designs, production continuity, and applications subject to RoHS regulatory requirements. Tube packaging provides standard component handling and storage.

Selection between these parts should be based on regulatory requirements, supply chain availability, and design lifecycle phase. Both parts are electrically and mechanically interchangeable within the specified parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can IRF9Z14LPBF be used as a direct replacement for IRF9Z14L in existing designs?

A: Yes. The IRF9Z14LPBF is electrically and mechanically equivalent to the IRF9Z14L. All electrical parameters, including voltage rating, current capacity, on-state resistance, and thermal characteristics, are identical. The Through Hole I2PAK package configuration is the same, enabling direct PCB compatibility without circuit modification.

Q: What is the difference between IRF9Z14L and IRF9Z14LPBF?

A: The primary differences are product status and regulatory compliance. The IRF9Z14L is obsolete and RoHS non-compliant. The IRF9Z14LPBF is an active product with ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Why is the IRF9Z14L classified as obsolete?

A: The IRF9Z14L has been discontinued by the manufacturer. The IRF9Z14LPBF serves as the active replacement product with equivalent electrical performance and improved regulatory compliance.

Q: Are there packaging differences between these parts?

A: The IRF9Z14LPBF is supplied in Tube packaging, which is the standard distribution format for active products. The IRF9Z14L packaging specification is not detailed in the available data. Both parts use the same TO-262-3 Long Leads, I2PAK, TO-262AA package case.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by matching the following parameters: Drain-to-source voltage (60V), continuous drain current (6.7A @ 25°C), on-state resistance (500 mOhm @ 4A, 10V), gate threshold voltage (4V @ 250µA), gate charge (12 nC @ 10V), maximum gate-source voltage (±20V), input capacitance (270 pF @ 25V), power dissipation (3.7W Ta, 43W Tc), and operating temperature range (-55°C to 175°C). The Through Hole I2PAK package configuration must also match.

Q: Is RoHS compliance a functional requirement or a regulatory requirement?

A: RoHS compliance is a regulatory requirement determined by the end-use application and market jurisdiction. The IRF9Z14LPBF is ROHS3 compliant, making it suitable for applications subject to RoHS directives. The IRF9Z14L is RoHS non-compliant and should be used only in applications where RoHS compliance is not mandated.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts have identical operating temperature ranges of -55°C to 175°C (TJ) and identical power dissipation ratings (3.7W Ta, 43W Tc). Thermal performance is equivalent.

Q: What is the significance of the "LPBF" suffix in IRF9Z14LPBF?

A: The "LPBF" suffix indicates the part is lead-free and RoHS compliant. This designation reflects the manufacturing process and material composition used to meet regulatory requirements.
