Key Parameters

Substitute Part Grouping Explanation

Substitution for the MIC4423CWM TR is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side only
• Number of Drivers: 2 independent channels
• Gate Type: N-Channel and P-Channel MOSFET support
• Voltage - Supply: 4.5V ~ 18V range
• Logic Voltage Thresholds: VIL 0.8V, VIH 2.4V
• Current - Peak Output: 3A source and sink capability
• Input Type: Inverting logic
• Package / Case: 16-SOIC form factor
• Mounting Type: Surface Mount

Substitute parts are grouped into two categories: Direct Equivalents (matching all electrical and mechanical parameters with identical or improved specifications) and Upgrade Options (offering extended operating temperature range or improved switching characteristics while maintaining full electrical compatibility).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Active Status, Matching Specifications):

MIC4423ZWM-TR is the direct active equivalent to MIC4423CWM TR. Both parts maintain identical electrical specifications, operating temperature range, and switching characteristics. MIC4423ZWM-TR is ROHS3 compliant, addressing regulatory requirements where the original part does not. This part is recommended for designs requiring minimal qualification effort and direct pin-compatible replacement.

Direct Equivalent (Improved Switching Performance):

TC4423COE and TC4423COE713 provide improved switching performance with reduced rise and fall times (23ns/25ns versus 28ns/32ns). Both maintain the 0°C to 150°C operating temperature range and are ROHS3 compliant. TC4423COE713 is supplied in Tape & Reel packaging, matching the original part's delivery format. TC4423COE is supplied in Tube packaging. These parts are suitable for applications where faster switching transitions provide system-level benefits.

Upgrade Option (Extended Temperature Range):

TC4423EOE, TC4423EOE713, TC4423VOE, and TC4423VOE713 extend the operating temperature range to -40°C to 150°C, providing enhanced performance in extreme temperature environments. All four parts feature improved switching characteristics (23ns/25ns) and ROHS3 compliance. TC4423EOE713 and TC4423VOE713 are supplied in Tape & Reel format; TC4423EOE and TC4423VOE are supplied in Tube format. These parts are recommended for applications requiring operation below 0°C or where extended temperature margin is specified.

Frequently Asked Questions (FAQ)

Q: Can MIC4423ZWM-TR be used as a direct replacement for MIC4423CWM TR?

A: Yes. MIC4423ZWM-TR is electrically and mechanically identical to MIC4423CWM TR, with matching supply voltage range (4.5V ~ 18V), peak output current (3A source/sink), logic thresholds, and operating temperature range (0°C ~ 150°C). The primary difference is ROHS3 compliance status. Both are supplied in Tape & Reel packaging.

Q: What is the difference between TC4423COE and TC4423COE713?

A: Both parts are electrically identical. TC4423COE713 is supplied in Tape & Reel (TR) packaging with a 713 reel designation, while TC4423COE is supplied in Tube packaging. The "713" designation indicates the specific reel format used for automated assembly. Select based on your procurement and assembly process requirements.

Q: Why do TC4423EOE and TC4423VOE have different part numbers if they are functionally equivalent?

A: TC4423EOE and TC4423VOE are both Microchip Technology products with identical electrical specifications and extended temperature range (-40°C ~ 150°C). The different alphanumeric designations reflect internal Microchip product line classifications. Both are suitable substitutes for applications requiring extended temperature operation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (MIC4423ZWM-TR, TC4423COE, TC4423COE713, TC4423EOE, TC4423EOE713, TC4423VOE, TC4423VOE713) are ROHS3 compliant. The original MIC4423CWM TR is RoHS non-compliant.

Q: What packaging options are available for Tape & Reel delivery?

A: MIC4423ZWM-TR, TC4423COE713, TC4423EOE713, and TC4423VOE713 are all available in Tape & Reel (TR) packaging. These parts are suitable for high-volume automated assembly processes.

Q: Do the substitute parts maintain the same pin configuration and footprint?

A: Yes. All substitute parts use the 16-SOIC (0.295", 7.50mm Width) package, maintaining identical pin configuration and PCB footprint compatibility with MIC4423CWM TR.

Q: Which substitute part offers the best switching performance?

A: TC4423COE, TC4423COE713, TC4423EOE, TC4423EOE713, TC4423VOE, and TC4423VOE713 all provide improved switching performance with rise/fall times of 23ns/25ns, compared to 28ns/32ns for the original MIC4423CWM TR and MIC4423ZWM-TR.
