TC54VC1802ECB713 Equivalent & Substitute Parts

Part Overview

The TC54VC1802ECB713 is a single-channel power management supervisor IC manufactured by Microchip Technology, designed for reset and power-on reset applications. This device operates as a push-pull, totem pole output supervisor with a 1.8V voltage threshold and active-low reset functionality. The component is currently in active product status with 4400 units available in inventory. Alternative equivalent parts may be required due to supply chain considerations, design optimization, or specific compliance requirements in target applications.

Substitute Part Grouping Explanation

Substitution eligibility for the TC54VC1802ECB713 is determined by strict alignment of the following critical parameters:

• Voltage Threshold: Must be 1.8V to maintain circuit functionality and protection thresholds
• Number of Channels: Must be single-channel (1 channel) to match functional requirements
• Output Type: Must be push-pull, totem pole configuration for direct pin compatibility
• Reset Logic: Must be active-low to ensure proper reset signal behavior
• Package Type: Must be SOT-23-3 or equivalent TO-236-3 footprint for PCB compatibility
• Mounting Type: Must be surface mount to match assembly process requirements

The MAX6333UR18D3+T from Analog Devices Inc./Maxim Integrated meets all substitution criteria across these parameters, establishing it as a qualified equivalent part for this application.

Parameter Comparison

Engineering Selection Recommendations

The MAX6333UR18D3+T qualifies as a direct functional equivalent to the TC54VC1802ECB713 based on matching electrical and mechanical parameters. Both devices are active products with unlimited moisture sensitivity ratings and identical package footprints.

The MAX6333UR18D3+T offers two additional advantages:

• Extended Operating Temperature Range: The MAX6333 operates to 125°C versus 85°C for the TC54VC, providing broader thermal margin in applications requiring higher temperature performance.
• RoHS3 Compliance: The MAX6333UR18D3+T is ROHS3 compliant, whereas the TC54VC1802ECB713 is RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulatory requirements.

Both parts maintain identical reset timeout behavior and are supplied in tape and reel packaging suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the MAX6333UR18D3+T be used as a direct replacement for the TC54VC1802ECB713?

A: Yes. Both devices share identical voltage thresholds (1.8V), output configurations (push-pull, totem pole), reset logic (active-low), and package footprints (SOT-23-3). Pin-to-pin compatibility is established across all functional parameters.

Q: What is the difference in operating temperature ranges?

A: The TC54VC1802ECB713 operates from -40°C to 85°C, while the MAX6333UR18D3+T operates from -40°C to 125°C. The MAX6333 provides an extended upper temperature limit of 40°C, which may be beneficial in high-temperature environments but is not required for standard applications within the TC54VC range.

Q: Does the RoHS compliance difference affect substitution?

A: RoHS compliance is a regulatory and supply chain consideration, not a functional one. The MAX6333UR18D3+T's ROHS3 compliance makes it suitable for applications with RoHS requirements, whereas the TC54VC1802ECB713's non-compliance may restrict its use in certain markets or applications. Substitution should be evaluated based on your specific regulatory requirements.

Q: Are the package designations SOT-23A-3 and SOT-23-3 interchangeable?

A: Both designations refer to functionally equivalent three-pin surface-mount packages with identical footprints and pin assignments. The "A" variant designation does not affect physical or electrical compatibility in this application.

Q: What is the reset timeout specification?

A: The TC54VC1802ECB713 does not specify a reset timeout value in the provided data. The MAX6333UR18D3+T specifies a 100ms minimum reset timeout. Both devices function as active-low reset supervisors; the timeout specification indicates the minimum duration the reset output remains asserted after the voltage threshold is crossed.

Q: Can I use either part interchangeably in new designs?

A: Yes. Both parts are active products with identical functional specifications for the core supervisor application. Selection between them should be based on supply availability, temperature requirements, and compliance certifications relevant to your application.
