APT5010LFLLG Equivalent & Substitute Parts

Part Overview

The APT5010LFLLG is an N-Channel power MOSFET manufactured by Microchip Technology, rated for 500V drain-to-source voltage with 46A continuous drain current at 25°C. This device is housed in a TO-264 through-hole package and is part of the POWER MOS 7® series. The part is currently in active production status with 2000 units in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter ranges. Alternative models may be required due to inventory constraints, lead time considerations, or application-specific performance requirements that fall within acceptable tolerance windows.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the APT5010LFLLG is determined by strict equivalence across the following critical parameters:

Voltage Rating: Both the main part and substitute must maintain a Drain to Source Voltage (Vdss) of 500V to ensure safe operation in the target application circuit.

Package Compatibility: The substitute must use the TO-264 through-hole package format (TO-264-3 or TO-264AA) to ensure mechanical fit and thermal interface compatibility with existing PCB layouts and heat sink assemblies.

On-State Resistance (Rds On): The maximum on-state resistance specification at rated gate voltage (10V) must not exceed the main part specification to maintain acceptable power dissipation and thermal performance.

Gate Voltage Range: The substitute must support the same maximum gate voltage (±30V) to ensure compatibility with existing gate drive circuits.

Operating Temperature Range: The substitute must support the full operating temperature range of -55°C to 150°C (TJ) to maintain performance across all application environments.

Regulatory Compliance: Both parts must maintain ROHS3 compliance and REACH unaffected status to meet supply chain and environmental requirements.

The IXTK60N50L2 meets all substitution criteria while offering enhanced current handling capability (60A versus 46A) and increased power dissipation rating (960W versus 520W), making it suitable for applications requiring higher performance margins.

Parameter Comparison

Engineering Selection Recommendations

APT5010LFLLG Selection Criteria:

The APT5010LFLLG is the primary choice when the application requires the exact specifications of the POWER MOS 7® series from Microchip Technology. This part is suitable for applications with continuous drain current requirements up to 46A and power dissipation up to 520W. The lower gate charge (95 nC) and input capacitance (4360 pF) provide faster switching characteristics, which may be advantageous in high-frequency switching applications. The part maintains active production status with adequate inventory availability.

IXTK60N50L2 Selection Criteria:

The IXTK60N50L2 is a suitable substitute when higher current handling capability or increased thermal headroom is required. This part supports continuous drain current up to 60A and power dissipation up to 960W, providing a 30% increase in current capacity and an 85% increase in power dissipation capability compared to the main part. Both parts maintain identical voltage ratings (500V), gate voltage ranges (±30V), and operating temperature ranges (-55°C to 150°C). Both parts are ROHS3 compliant and REACH unaffected.

Compliance and Regulatory Considerations:

Both parts meet ROHS3 compliance requirements and maintain REACH unaffected status, ensuring compatibility with current supply chain and environmental regulations. Both parts carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling. Both parts are classified under the same HTSUS code (8541.29.0095) and ECCN classification (EAR99).

Frequently Asked Questions (FAQ)

Q: Can the IXTK60N50L2 be used as a direct replacement for the APT5010LFLLG in all applications?

A: The IXTK60N50L2 is mechanically and electrically compatible with the APT5010LFLLG in applications where the APT5010LFLLG specifications are met. The substitute part exceeds the main part specifications in current capacity (60A versus 46A) and power dissipation (960W versus 520W). However, the IXTK60N50L2 exhibits higher gate charge (610 nC versus 95 nC) and input capacitance (24000 pF versus 4360 pF), which may affect switching speed and gate drive circuit requirements. Applications must be evaluated for compatibility with these parameter differences.

Q: Are both parts available in the same package?

A: Yes. Both the APT5010LFLLG and IXTK60N50L2 are available in TO-264-3 and TO-264AA through-hole packages. This ensures mechanical compatibility with existing PCB layouts and heat sink assemblies without modification.

Q: What is the significance of the different gate threshold voltage specifications?

A: The APT5010LFLLG specifies a gate threshold voltage (Vgs(th)) of 5V at 2.5mA, while the IXTK60N50L2 specifies 4.5V at 250µA. These measurements are taken at different test currents, which is standard practice across different manufacturers. Both specifications fall within acceptable ranges for typical gate drive circuits operating at 10V.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the APT5010LFLLG and IXTK60N50L2 are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (Unlimited). Both parts are classified under HTSUS code 8541.29.0095 and ECCN classification EAR99. Both parts meet identical environmental and regulatory requirements.

Q: What are the key differences in switching characteristics between these parts?

A: The primary difference in switching characteristics is the gate charge specification. The APT5010LFLLG has a gate charge of 95 nC at 10V, while the IXTK60N50L2 has a gate charge of 610 nC at 10V. Higher gate charge requires more energy from the gate drive circuit to switch the device. The APT5010LFLLG also has lower input capacitance (4360 pF versus 24000 pF), which contributes to faster switching transitions. Applications with stringent switching speed requirements should account for these differences.

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

A: Both parts support the same operating temperature range (-55°C to 150°C) and maximum gate voltage (±30V). However, the differences in gate charge and input capacitance mean that gate drive circuit design may require adjustment. The APT5010LFLLG's lower gate charge and capacitance make it more suitable for high-frequency applications where switching losses must be minimized. The IXTK60N50L2 is suitable for high-frequency applications where higher current capacity is prioritized over switching speed.

Q: What inventory considerations should be evaluated?

A: The APT5010LFLLG has 2000 units in stock, while the IXTK60N50L2 has 2400 units in stock. Both parts maintain adequate inventory for immediate availability. Selection between these parts may be influenced by lead time requirements and supply chain considerations.
