Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC4424CWM is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side
• Number of Drivers: 2
• Gate Type: N-Channel, P-Channel MOSFET
• Voltage - Supply: 4.5V ~ 18V
• Logic Voltage - VIL, VIH: 0.8V, 2.4V
• Current - Peak Output (Source, Sink): 3A, 3A
• Input Type: Non-Inverting
• Package / Case: 16-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

Substitute parts are grouped into two categories:

Direct Substitutes (Identical Electrical Specifications):

• MIC4424ZWM: Same base product with active status and improved RoHS3 compliance
• TC4424COE: Microchip TC4424 series variant with identical electrical parameters
• TC4424COE713: TC4424 series with tape & reel packaging option

Upgrade Substitutes (Extended Operating Temperature Range):

• TC4424EOE: Extended temperature range (-40°C to 150°C) with faster switching characteristics
• TC4424EOE713: Extended temperature range with tape & reel packaging
• TC4424VOE: Extended temperature range with tube packaging
• TC4424VOE713: Extended temperature range with tape & reel packaging

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Temperature Range):

MIC4424ZWM is the primary direct substitute for MIC4424CWM. Both maintain the 0°C to 150°C operating temperature range and identical electrical specifications. MIC4424ZWM offers the advantage of active product status and ROHS3 compliance, making it suitable for new designs and production continuity.

TC4424COE and TC4424COE713 are functionally equivalent alternatives from the TC4424 product line. These parts deliver faster switching characteristics (23ns/25ns rise/fall time versus 28ns/32ns) while maintaining all other electrical parameters. TC4424COE713 provides tape & reel packaging for automated assembly operations.

For Extended Temperature Applications:

TC4424EOE, TC4424EOE713, TC4424VOE, and TC4424VOE713 extend the operating temperature range to -40°C to 150°C, accommodating industrial and automotive environments requiring lower temperature operation. These parts also feature improved switching performance (23ns/25ns rise/fall time).

TC4424EOE713 and TC4424VOE713 offer the highest inventory availability (5084 and 1137 units respectively) with tape & reel packaging for high-volume production.

Compliance Considerations:

All substitute parts are ROHS3 compliant, addressing regulatory requirements that the obsolete MIC4424CWM does not meet. All parts maintain REACH unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can MIC4424ZWM directly replace MIC4424CWM in existing designs?

A: Yes. MIC4424ZWM maintains identical electrical specifications, supply voltage range (4.5V to 18V), peak output current (3A source/sink), logic voltage thresholds, and operating temperature range (0°C to 150°C). The 16-SOIC package and surface mount configuration are identical. The primary difference is product status (active versus obsolete) and improved RoHS3 compliance.

Q: What is the difference between TC4424COE and TC4424EOE?

A: Both parts are functionally equivalent in terms of supply voltage, output current, and package. The key difference is operating temperature range: TC4424COE operates from 0°C to 150°C, while TC4424EOE extends to -40°C to 150°C. TC4424EOE also features faster switching characteristics (23ns/25ns rise/fall time versus 28ns/32ns). Select TC4424EOE for applications requiring extended low-temperature operation.

Q: What does the "713" suffix indicate in part numbers like TC4424COE713?

A: The "713" suffix indicates tape & reel packaging format, suitable for automated pick-and-place assembly. Parts without this suffix are supplied in tube packaging. Both packaging formats contain identical die and electrical specifications.

Q: Are all substitute parts pin-compatible with MIC4424CWM?

A: Yes. All substitute parts use the 16-SOIC package with identical pinout and electrical interface. No PCB layout modifications are required for substitution.

Q: Which substitute part offers the best availability?

A: TC4424EOE713 provides the highest inventory level at 5084 units, combined with extended temperature range (-40°C to 150°C) and tape & reel packaging for production efficiency.

Q: Do substitute parts maintain the same logic voltage thresholds?

A: Yes. All substitute parts maintain VIL of 0.8V and VIH of 2.4V, ensuring compatibility with existing control signal conditioning circuits.
