Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRLI640G is determined by the following critical parameters:

• Drain to Source Voltage (Vdss): Must equal or exceed 200V
• Continuous Drain Current (Id): Must equal or exceed 9.9A at 25°C
• On-State Resistance (Rds On): Must not exceed 180 mOhm at the specified gate voltage and drain current
• Power Dissipation: Must support minimum 40W at case temperature
• Operating Temperature Range: Must encompass -55°C to 150°C
• Mounting Type: Through-hole configuration required
• Package Compatibility: TO-220-3 or equivalent footprint

Substitute parts are grouped into two categories:

Parametric Equivalents: Parts with identical or near-identical electrical specifications and the same TO-220-3 package footprint.

Functional Substitutes: Parts that meet or exceed the electrical requirements but may have enhanced performance characteristics, different package variants (TO-220F, TO-220FM, TO-220FP, TO-220AB), or improved compliance status.

Engineering Selection Recommendations

First Choice for Direct Replacement: IRLI640GPBF

The IRLI640GPBF is the direct parametric equivalent to the IRLI640G. It maintains identical electrical specifications including 200V Vdss, 9.9A continuous drain current, and 180 mOhm on-state resistance. The primary distinction is product status: IRLI640GPBF is active and ROHS3 compliant, whereas the original IRLI640G is obsolete and non-compliant. The IRLI640GPBF is packaged in tube format and is available in high inventory (2918 pieces). This part requires no circuit redesign and provides full functional compatibility.

Active Alternatives with Enhanced Performance: FQPF19N20C, IRF200B211, RCX160N20, STF19NF20

These parts exceed the minimum electrical requirements of the IRLI640G while maintaining the 200V Vdss rating and through-hole mounting configuration. All are active products with ROHS3 compliance. Each offers distinct advantages:

• FQPF19N20C (onsemi): Highest continuous drain current at 19A with 170 mOhm Rds On. Suitable for applications requiring higher current capacity.
• IRF200B211 (Infineon): Highest power dissipation rating at 80W with extended operating temperature to 175°C. Recommended for high-power applications.
• RCX160N20 (Rohm): 16A continuous drain current with 180 mOhm Rds On. Balanced performance with active status.
• STF19NF20 (STMicroelectronics): 15A continuous drain current with improved 160 mOhm Rds On. Lower power dissipation rating at 25W.

Package Variant Considerations: FQPF19N20, FQPF19N20C, IRLS640A, RCX160N20, and STF19NF20 use TO-220F, TO-220FM, or TO-220FP package variants. These variants maintain mechanical compatibility with TO-220-3 footprints but may have minor dimensional differences in tab isolation or mounting hole configuration. Verification of PCB layout compatibility is required before selection.

Obsolete Status Parts: IRLS640A shares obsolete status with the original IRLI640G but offers ROHS3 compliance. This part is suitable only if active product alternatives are unavailable and compliance requirements are secondary.

Frequently Asked Questions (FAQ)

Q: Can IRLI640GPBF be used as a direct drop-in replacement for IRLI640G?

A: Yes. The IRLI640GPBF is electrically and mechanically identical to the IRLI640G. Both devices feature 200V Vdss, 9.9A continuous drain current, 180 mOhm on-state resistance, and TO-220-3 packaging. The primary difference is product status and compliance certification. IRLI640GPBF is active and ROHS3 compliant.

Q: What is the difference between TO-220-3, TO-220F-3, TO-220FM, TO-220FP, and TO-220AB packages?

A: All variants are through-hole packages with three leads (drain, gate, source) and are mechanically compatible with standard TO-220-3 PCB footprints. Differences exist in tab isolation design and mounting hole configuration. TO-220-3 features an isolated tab, while TO-220F, TO-220FM, TO-220FP, and TO-220AB variants may have different tab configurations. Consult PCB layout specifications and component datasheets to confirm compatibility before assembly.

Q: Can I use FQPF19N20C instead of IRLI640G in my circuit?

A: Yes, with verification. FQPF19N20C exceeds the electrical requirements of IRLI640G: 200V Vdss (equal), 19A continuous drain current (exceeds 9.9A requirement), and 170 mOhm Rds On (within specification). The device operates across -55°C to 150°C, matching the temperature range. However, FQPF19N20C uses a TO-220F-3 package variant. Confirm PCB footprint compatibility before selection.

Q: Why do some substitute parts have lower power dissipation ratings than the IRLI640G?

A: Power dissipation ratings depend on thermal design, die size, and package thermal characteristics. STF19NF20, for example, is rated at 25W (Tc) despite higher continuous drain current (15A) than IRLI640G (9.9A). This reflects the specific thermal properties of that device. Lower power dissipation ratings do not indicate inferior performance if the device meets the circuit's actual thermal requirements. Thermal analysis of your specific application is necessary to determine suitability.

Q: Are all substitute parts ROHS3 compliant?

A: No. FQPF19N20 (Fairchild Semiconductor) does not specify RoHS status in the provided data. All other active substitute parts (IRLI640GPBF, FQPF19N20C, IRF200B211, RCX160N20, STF19NF20) are ROHS3 compliant. If RoHS compliance is a requirement, verify the specific part's certification before procurement.

Q: What is the minimum continuous drain current I should select for a substitute part?

A: The substitute part must support at least 9.9A continuous drain current at 25°C to meet the IRLI640G specification. All listed substitute parts meet or exceed this requirement. Selection of a part with higher current rating provides design margin but does not improve circuit performance if the application current is lower.

Q: Can I use IRF200B211 in a circuit designed for IRLI640G?

A: Yes. IRF200B211 meets all critical electrical requirements: 200V Vdss, 12A continuous drain current (exceeds 9.9A), and 170 mOhm Rds On. The device operates across -55°C to 175°C, exceeding the -55°C to 150°C requirement. IRF200B211 offers higher power dissipation (80W) and uses a TO-220AB package. Confirm PCB footprint compatibility and verify that the enhanced performance characteristics do not introduce unintended circuit behavior before implementation.

Q: Is IRLS640A a suitable replacement for IRLI640G?

A: IRLS640A meets the electrical specifications of IRLI640G: 200V Vdss, 9.8A continuous drain current (equivalent to 9.9A), and 180 mOhm Rds On. However, IRLS640A is classified as obsolete, the same status as the original IRLI640G. IRLI640GPBF is the preferred alternative because it is active and ROHS3 compliant. IRLS640A should be selected only if IRLI640GPBF is unavailable and compliance requirements are not critical.
