TC4425EPA Equivalent & Substitute Parts

Part Overview

The TC4425EPA is a low-side gate driver IC manufactured by Microchip Technology, designed for driving N-Channel and P-Channel MOSFETs in independent configurations. This 8-PDIP through-hole component operates across a supply voltage range of 4.5V to 18V and features both inverting and non-inverting input types. The device is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent functional performance, package compatibility, and electrical specifications align within acceptable operational parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TC4425EPA is determined by the following critical parameters:

• Package compatibility: 8-DIP (0.300", 7.62mm) through-hole mounting
• Driven configuration: Low-side gate driver topology
• Gate type support: N-Channel and P-Channel MOSFET capability
• Supply voltage range: 4.5V ~ 18V operation
• Input type: Inverting and non-inverting configurations
• Operating temperature range: -40°C ~ 150°C (TJ)
• Compliance status: RoHS3 compliance required

The TC4425AVPA qualifies as a direct substitute based on identical package, configuration, gate type support, supply voltage range, input types, and operating temperature specifications. Variations in peak output current (4.5A vs. 3A) and rise/fall time characteristics represent performance enhancements rather than compatibility limitations.

Parameter Comparison

Engineering Selection Recommendations

Both TC4425EPA and TC4425AVPA maintain Active product status with identical RoHS3 compliance and REACH unaffected designations. Selection between these parts is based on application-specific current requirements and switching speed performance. The TC4425EPA operates at 3A peak output current with 23ns/25ns rise/fall times, while the TC4425AVPA provides enhanced performance at 4.5A peak output current with 12ns/12ns rise/fall times. Applications requiring higher gate drive current or faster switching transitions benefit from TC4425AVPA selection. Both devices share identical supply voltage ranges, logic thresholds, and operating temperature specifications, ensuring functional interchangeability within their respective current and speed ratings.

Frequently Asked Questions (FAQ)

Q: Can TC4425AVPA directly replace TC4425EPA in existing designs?

A: Yes, TC4425AVPA is a direct substitute. Both devices share identical package (8-DIP), supply voltage range (4.5V ~ 18V), logic thresholds (0.8V/2.4V), input types (inverting/non-inverting), and operating temperature range (-40°C ~ 150°C). The TC4425AVPA provides higher peak output current (4.5A vs. 3A) and faster switching times (12ns vs. 23ns/25ns), making it suitable for applications where the original part is specified.

Q: What are the key differences between TC4425EPA and TC4425AVPA?

A: The primary differences are peak output current capability and switching speed. TC4425AVPA delivers 4.5A source/sink current compared to TC4425EPA's 3A, and features faster rise/fall times of 12ns versus 23ns/25ns. All other electrical and mechanical specifications remain identical.

Q: Are both parts RoHS3 compliant?

A: Yes, both TC4425EPA and TC4425AVPA are RoHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating and REACH unaffected status.

Q: Does package compatibility extend to surface-mount alternatives?

A: No. Both specified parts are through-hole 8-DIP packages. Surface-mount alternatives would require different package designations and are not included in this substitution analysis.

Q: What supply voltage range do these gate drivers support?

A: Both TC4425EPA and TC4425AVPA operate across 4.5V to 18V supply voltage range, supporting standard logic and power supply configurations.
