FAN3226CMPX Equivalent & Substitute Parts

Part Overview

The FAN3226CMPX is a low-side gate driver IC manufactured by onsemi, designed for driving N-Channel MOSFETs in power management applications. This inverting gate driver operates across a 4.5V to 18V supply range and delivers 3A peak output current on both source and sink channels. The device is housed in an 8-MLP (3x3) surface mount package and maintains Active product status with full RoHS3 compliance.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter ranges for low-side gate driver applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FAN3226CMPX is determined by the following critical parameters:

• Driven Configuration: Must be Low-Side
• Number of Drivers: Must be 2 independent channels
• Input Type: Must be Inverting
• Voltage - Supply Range: Must encompass or match 4.5V ~ 18V
• Current - Peak Output: Must meet or exceed 3A source and 3A sink capability
• Mounting Type: Must be Surface Mount
• Package Compatibility: Physical footprint must accommodate 8-pin configurations
• Compliance: Must maintain RoHS3 compliance

The substitute parts listed below satisfy these core electrical and mechanical requirements while maintaining functional equivalence for low-side gate driver applications.

Engineering Selection Recommendations

MCP14E6-E/MF (Microchip Technology)

This substitute maintains full compatibility with the FAN3226CMPX across supply voltage, input type, and package class. However, peak output current is limited to 2A source and 2A sink, which is below the 3A specification of the primary part. This device is suitable only for applications where the 2A output current specification is acceptable. Extended operating temperature range to 150°C provides additional thermal margin. RoHS3 compliance and MSL 1 rating are maintained.

MCP14E9-E/MF (Microchip Technology)

This substitute provides direct electrical equivalence to the FAN3226CMPX with matching 3A peak output current on both source and sink channels. Supply voltage range, inverting input configuration, and dual-channel architecture are identical. Rise and fall times are slightly longer (14ns and 17ns respectively) compared to the primary part. Extended operating temperature range to 150°C and RoHS3 compliance are maintained. MSL 1 rating ensures unlimited shelf life.

UCC27523DSDT (Texas Instruments)

This substitute exceeds the electrical specifications of the FAN3226CMPX with 5A peak output current on both source and sink channels. Supply voltage range and inverting input configuration match the primary part. Rise and fall times are faster (7ns and 6ns) than the primary device. Operating temperature range extends to 140°C. Package footprint is compatible (8-WDFN). RoHS3 compliance is maintained. MSL rating is 2 (1 Year), which requires controlled storage conditions compared to the MSL 1 rating of the primary part.

All substitute parts maintain Active product status and full regulatory compliance (RoHS3, REACH Unaffected, EAR99).

Frequently Asked Questions (FAQ)

Q: Can MCP14E6-E/MF be used as a direct replacement for FAN3226CMPX?

A: MCP14E6-E/MF is electrically compatible across supply voltage, input type, and channel configuration. However, its 2A peak output current specification is below the 3A requirement of the FAN3226CMPX. Use this substitute only if your application circuit operates within 2A output current limits.

Q: What is the primary difference between MCP14E9-E/MF and MCP14E6-E/MF?

A: Both devices share identical supply voltage range, input type, and package class. The key difference is peak output current: MCP14E9-E/MF provides 3A source and sink current, matching the FAN3226CMPX, while MCP14E6-E/MF is limited to 2A.

Q: Is UCC27523DSDT a suitable substitute if my application requires higher output current?

A: Yes. UCC27523DSDT delivers 5A peak output current on both source and sink channels, exceeding the 3A specification of the FAN3226CMPX. All other electrical parameters (supply voltage, input type, channel configuration) are compatible. Note that MSL rating is 2 (1 Year) rather than MSL 1 (Unlimited).

Q: Are there package footprint differences between these substitutes?

A: FAN3226CMPX and UCC27523DSDT both use 8-WDFN Exposed Pad packages. MCP14E6-E/MF and MCP14E9-E/MF use 8-VDFN Exposed Pad packages. While both are 8-pin DFN variants with similar dimensions, PCB layout verification is required to confirm mechanical compatibility in your specific application.

Q: Do all substitute parts meet the same compliance standards as FAN3226CMPX?

A: All substitute parts maintain RoHS3 compliance and REACH Unaffected status. Moisture sensitivity differs: FAN3226CMPX, MCP14E6-E/MF, and MCP14E9-E/MF are rated MSL 1 (Unlimited shelf life). UCC27523DSDT is rated MSL 2 (1 Year), requiring controlled storage conditions.

Q: What operating temperature range should I consider for thermal design?

A: FAN3226CMPX operates to 125°C (TA). MCP14E6-E/MF and MCP14E9-E/MF extend to 150°C (TJ). UCC27523DSDT operates to 140°C (TJ). Extended temperature ratings provide additional design margin in high-temperature environments.
