TC4467CPD Equivalent & Substitute Parts

Part Overview

The TC4467CPD is a low-side gate driver IC manufactured by Microchip Technology, designed for driving N-Channel and P-Channel MOSFETs in power management applications. This inverting gate driver operates across a 4.5V to 18V supply range and delivers 1.2A peak output current for both source and sink configurations. The device is housed in a 14-pin DIP package and is actively produced with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance, package compatibility, and functional characteristics align with the original specification, enabling direct replacement in circuit designs without modification.

The MIC4467ZN meets all substitution criteria and is classified as a manufacturer-recommended equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The MIC4467ZN is a direct substitute for the TC4467CPD based on electrical and mechanical equivalence. Both devices are manufactured by Microchip Technology, carry Active product status, and maintain identical compliance certifications including ROHS3 and REACH Unaffected status.

The MIC4467ZN exhibits faster rise and fall times (14ns and 13ns respectively) compared to the TC4467CPD (15ns each), representing improved switching performance. The operating temperature range differs, with the TC4467CPD rated to 150°C junction temperature and the MIC4467ZN to 70°C ambient temperature. Selection between these parts should account for the thermal environment of the application.

Both parts are available in production quantities and carry identical packaging, pinout, and functional specifications for low-side gate driving applications.

Frequently Asked Questions (FAQ)

Q: Can the MIC4467ZN replace the TC4467CPD in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent low-side gate drivers with identical supply voltage ranges, output current ratings, logic thresholds, and 14-DIP package specifications. Direct substitution is possible without circuit modification.

Q: What is the difference in operating temperature ratings?

A: The TC4467CPD is rated to 150°C junction temperature, while the MIC4467ZN is rated to 70°C ambient temperature. Applications requiring operation above 70°C ambient should use the TC4467CPD to ensure reliable performance within specified limits.

Q: Are the switching characteristics identical?

A: The MIC4467ZN exhibits faster rise and fall times (14ns/13ns) compared to the TC4467CPD (15ns/15ns). This represents improved switching performance and may reduce switching losses in high-frequency applications. Both values remain within acceptable ranges for standard gate driving applications.

Q: Do both parts have the same package footprint?

A: Yes. Both the TC4467CPD and MIC4467ZN use the 14-DIP (0.300", 7.62mm) through-hole package with identical pinout and mechanical dimensions, enabling direct board-level substitution.

Q: Are compliance certifications equivalent?

A: Yes. Both parts carry ROHS3 compliance, REACH Unaffected status, and unlimited moisture sensitivity rating (MSL 1), meeting identical regulatory and environmental requirements.
