Substitute Part Grouping Explanation

Substitution of the IRLS630A is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• FET Type: N-Channel topology
• Technology: MOSFET (Metal Oxide) construction
• Drain to Source Voltage (Vdss): 200V rating
• Continuous Drain Current (Id): Minimum 6.2A at 25°C (within 95% of original specification)
• Rds On (Max): 400 mOhm or lower at specified gate voltage
• Power Dissipation: 35W or higher
• Operating Temperature Range: -55°C to 150°C minimum

Mechanical Equivalence Criteria:

• Package Type: TO-220-3 through-hole configuration
• Mounting Type: Through-hole compatible with standard PCB layouts

The IRLI630GPBF manufactured by Vishay Siliconix meets all substitution criteria. This device maintains identical voltage ratings, comparable current ratings (6.2A versus 6.5A), equivalent on-resistance characteristics, and identical package configuration. The substitute part is classified as active product status, ensuring ongoing availability and supply chain support.

Engineering Selection Recommendations

IRLI630GPBF as Primary Substitute:

The IRLI630GPBF is the direct substitute for the obsolete IRLS630A. Selection of this part is based on the following engineering factors:

1. Electrical Compatibility: Both devices share identical voltage ratings (200V Vdss) and equivalent current handling (6.2A versus 6.5A represents 95% current retention). On-resistance specifications are identical at 400 mOhm, ensuring equivalent thermal performance in switching applications.

2. Mechanical Compatibility: Both devices utilize the TO-220-3 through-hole package, enabling direct PCB layout compatibility without redesign.

3. Product Status and Supply Chain: The IRLI630GPBF is classified as active product, ensuring long-term availability and supply continuity. The IRLS630A is obsolete, making substitution necessary for ongoing production support.

4. Compliance and Certifications: The IRLI630GPBF carries RoHS3 compliance certification, meeting current environmental and regulatory standards. Both devices share identical ECCN (EAR99) and HTSUS (8541.29.0095) classifications.

5. Thermal Performance: Power dissipation ratings are comparable (35W versus 36W), confirming equivalent thermal design margins in applications with existing thermal management solutions.

Frequently Asked Questions (FAQ)

Q: Can the IRLI630GPBF directly replace the IRLS630A without PCB modifications?

A: Yes. Both devices are housed in the TO-220-3 through-hole package with identical pin configurations and mechanical dimensions. Direct pin-for-pin substitution is possible without PCB layout changes.

Q: What is the current rating difference between these devices?

A: The IRLS630A is rated for 6.5A continuous drain current, while the IRLI630GPBF is rated for 6.2A. This represents a 4.6% reduction in maximum current capacity. Applications operating below 6.2A experience no functional impact. Applications requiring the full 6.5A rating require thermal analysis to confirm the IRLI630GPBF operates within acceptable junction temperature limits.

Q: Are the gate charge specifications identical?

A: No. The IRLS630A specifies 27 nC gate charge at 5V, while the IRLI630GPBF specifies 40 nC at 10V. Gate drive circuits must accommodate the higher gate charge of the substitute part. Verify gate driver output impedance and switching frequency compatibility.

Q: What is the difference in input capacitance?

A: The IRLS630A specifies 755 pF input capacitance at 25V, while the IRLI630GPBF specifies 1100 pF at 25V. The higher capacitance of the substitute part increases gate drive current requirements. High-frequency switching applications must verify gate driver capability.

Q: Are the maximum gate voltage ratings the same?

A: No. The IRLS630A permits ±20V maximum gate voltage, while the IRLI630GPBF permits ±10V. Gate drive circuits must be designed to operate within the ±10V limit of the substitute part.

Q: What packaging differences exist between these devices?

A: The IRLS630A is supplied in standard TO-220-3 packaging. The IRLI630GPBF is supplied in TO-220-3 Full Pack with isolated tab configuration. Both are through-hole compatible. Verify thermal interface requirements if the isolated tab feature is utilized in thermal management design.

Q: Is the IRLI630GPBF RoHS compliant?

A: Yes. The IRLI630GPBF is RoHS3 compliant. The IRLS630A compliance status is not specified in available documentation.

Q: What is the inventory status of these parts?

A: The IRLS630A has 823 pieces in stock as new original inventory. The IRLI630GPBF has 2139 pieces in stock as new original inventory, providing superior supply chain availability.
