Key Parameters

Substitute Part Grouping Explanation

Substitution of the MIC4468CWM TR is determined by strict equivalence across the following critical parameters:

• Driven configuration (low-side operation)
• Number of independent driver channels (4 channels)
• Gate type compatibility (N-Channel and P-Channel MOSFET support)
• Supply voltage range (4.5V ~ 18V)
• Peak output current specifications (1.2A source and sink)
• Input logic type (non-inverting)
• Package form factor (16-SOIC)
• Rise and fall time characteristics (14ns, 13ns)
• Operating temperature range (0°C ~ 70°C)

The MIC4468ZWM-TR qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility across all these parameters.

Parameter Comparison

Engineering Selection Recommendations

The MIC4468ZWM-TR is the direct substitute for the obsolete MIC4468CWM TR. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin compatibility and functional equivalence in circuit applications.

The MIC4468ZWM-TR offers additional advantages: it maintains active product status with Microchip Technology, ensuring long-term availability and supply chain reliability. The substitute part achieves ROHS3 compliance, meeting current environmental and regulatory standards, whereas the original part does not. The moisture sensitivity level difference (MSL 2 versus MSL 1) reflects standard handling requirements for the active product variant.

Selection of the MIC4468ZWM-TR is appropriate for new designs and replacement applications requiring compliance with modern regulatory frameworks and assured component availability.

Frequently Asked Questions (FAQ)

Q: Can the MIC4468ZWM-TR be used as a direct replacement for the MIC4468CWM TR?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including supply voltage range, output current ratings, timing characteristics, and package form factor. Pin-for-pin substitution is valid.

Q: What is the primary reason to transition from MIC4468CWM TR to MIC4468ZWM-TR?

A: The MIC4468CWM TR is obsolete. The MIC4468ZWM-TR is an active product with assured availability from Microchip Technology and meets ROHS3 compliance requirements.

Q: Are there any differences in handling or storage between these two parts?

A: The MIC4468ZWM-TR has a moisture sensitivity level (MSL) of 2 with a 1-year shelf life, compared to MSL 1 (unlimited) for the original part. Standard moisture control procedures apply during storage and handling of the substitute part.

Q: Do both parts support the same gate driver configurations?

A: Yes. Both the MIC4468CWM TR and MIC4468ZWM-TR provide four independent low-side gate drivers for N-Channel and P-Channel MOSFETs with identical electrical characteristics.

Q: Is the 16-SOIC package identical between both parts?

A: Yes. Both parts use the 16-SOIC package with 0.295" width (7.50mm), ensuring mechanical compatibility with existing PCB layouts and sockets.
