TC4420VAT Equivalent & Substitute Parts

Part Overview

The TC4420VAT is a low-side gate driver IC manufactured by Microchip Technology, designed for driving N-Channel and P-Channel MOSFETs in power management applications. This non-inverting gate driver operates within a 4.5V to 18V supply voltage range and delivers 6A peak output current for both source and sink configurations. The device is housed in a TO-220-5 through-hole package and maintains active product status with full RoHS3 compliance. Substitute parts are identified when equivalent electrical performance, package compatibility, and operational specifications align with the original design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TC4420VAT are qualified based on the following critical parameters that determine functional equivalence:

• Package Compatibility: TO-220-5 through-hole package required for direct PCB replacement
• Electrical Configuration: Low-side, single-channel, non-inverting gate driver topology
• Supply Voltage Range: 4.5V to 18V operation
• Output Current Capability: Minimum 6A peak source and sink current
• Gate Type Support: Compatibility with N-Channel and P-Channel MOSFETs
• Operating Temperature Range: -40°C to 150°C junction temperature
• Compliance Standards: RoHS3 compliance and active product status

The MCP1407-E/AT meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

The MCP1407-E/AT qualifies as a direct substitute for the TC4420VAT based on matching electrical specifications, identical package configuration, and equivalent compliance certifications. Both devices maintain active product status with full RoHS3 compliance and REACH unaffected designation. The MCP1407-E/AT provides faster rise and fall times (20ns versus 25ns) and extended gate type support including IGBT compatibility, representing a performance-equivalent or superior alternative. Selection between these parts should be based on availability, lead time, and inventory requirements, as both devices satisfy the functional and regulatory requirements for low-side gate driver applications.

Frequently Asked Questions (FAQ)

Q: Can the MCP1407-E/AT replace the TC4420VAT in existing designs?

A: Yes. Both devices share identical supply voltage ranges (4.5V to 18V), output current ratings (6A source/sink), package configuration (TO-220-5), and operating temperature specifications (-40°C to 150°C). Direct PCB substitution is supported without circuit modification.

Q: What are the key differences between these parts?

A: The MCP1407-E/AT features faster switching times (20ns rise/fall versus 25ns) and supports IGBT gate driving in addition to MOSFET configurations. All other electrical and mechanical parameters remain equivalent.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the TC4420VAT and MCP1407-E/AT carry ROHS3 compliance certification with MSL rating of 1 (unlimited moisture sensitivity level).

Q: Does package compatibility guarantee functional interchangeability?

A: Package compatibility combined with matching electrical specifications (supply voltage, output current, logic levels, input type, and operating temperature) ensures functional interchangeability. Both devices are non-inverting low-side gate drivers with identical TO-220-5 through-hole packages.

Q: Are there any supply chain or availability considerations?

A: Both parts are manufactured by Microchip Technology and maintain active product status. Selection should be based on current inventory levels and lead time requirements for your application.
