TSC213ICT Current Sense Amplifier Equivalent & Substitute Parts

Part Overview

The TSC213ICT is an active current sense amplifier manufactured by STMicroelectronics, designed for single-circuit current sensing applications. This linear amplifier operates across a wide supply voltage range of 2.7 V to 26 V and is housed in a compact 6-TSSOP (SC-70-6) surface mount package. The device is classified as Active product status and carries full RoHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

Current sense amplifiers are essential components in power management, battery monitoring, and load detection circuits where precise current measurement is required without introducing significant voltage drops. Equivalent and substitute parts become necessary when addressing supply chain constraints, design optimization requirements, or when enhanced performance specifications are beneficial to system performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the TSC213ICT is determined by electrical and mechanical parameter alignment within the current sense amplifier category. The primary substitution criteria include:

Electrical Compatibility Parameters:

• Single-circuit current sense amplifier topology
• Supply voltage range encompassing the original specification (minimum 2.7 V, maximum 26 V)
• Operating temperature range of -40°C to 125°C
• Surface mount packaging in 6-TSSOP/SC-88/SOT-363 form factor

Compliance & Environmental Parameters:

• RoHS3 compliance status
• Moisture sensitivity level MSL 1 (Unlimited)
• REACH unaffected classification
• Active product status

The NCV213RSQT2G from onsemi satisfies all substitution criteria through identical package compatibility, overlapping electrical specifications, and equivalent compliance certifications. Enhanced performance characteristics in the substitute part (lower input offset voltage, improved slew rate, reduced supply current) represent performance improvements rather than compatibility limitations.

Engineering Selection Recommendations

TSC213ICT Selection Criteria: The TSC213ICT remains the primary choice for applications where STMicroelectronics supply chain preference is established or where existing design validation has been completed with this specific manufacturer part number.

NCV213RSQT2G Selection Criteria: The NCV213RSQT2G serves as a direct substitute when supply availability of the TSC213ICT is constrained. This part offers enhanced electrical performance through lower input offset voltage (5 µV versus 100 µV), reduced supply current consumption (40 µA versus 65 µA), and improved slew rate (1.0 V/µs versus 0.85 V/µs). The NCV213RSQT2G carries AEC-Q100 automotive qualification and Zero-Drift series designation, indicating suitability for demanding automotive and industrial applications.

Both parts maintain identical RoHS3 compliance, MSL 1 moisture sensitivity rating, and REACH unaffected status. Both support the full -40°C to 125°C operating temperature range and are housed in compatible 6-TSSOP/SC-88/SOT-363 surface mount packages. The minimum supply voltage specification of the NCV213RSQT2G (2.2 V) provides extended low-voltage operation capability compared to the TSC213ICT (2.7 V minimum).

Frequently Asked Questions (FAQ)

Q: Can the NCV213RSQT2G directly replace the TSC213ICT in existing PCB designs?

A: Yes. Both devices share identical package specifications (6-TSSOP, SC-88, SOT-363) and pinout compatibility. No PCB layout modifications are required for mechanical or electrical substitution.

Q: What are the key electrical differences between these parts?

A: The NCV213RSQT2G provides superior input offset voltage accuracy (5 µV versus 100 µV), lower supply current (40 µA versus 65 µA), and faster slew rate (1.0 V/µs versus 0.85 V/µs). The NCV213RSQT2G also operates at lower minimum supply voltage (2.2 V versus 2.7 V). These represent performance enhancements rather than compatibility limitations.

Q: Are both parts compliant with automotive standards?

A: The TSC213ICT meets general industrial compliance requirements (RoHS3, REACH unaffected). The NCV213RSQT2G carries additional AEC-Q100 automotive qualification, making it suitable for automotive-grade applications requiring enhanced reliability documentation.

Q: What is the significance of the Zero-Drift designation on the NCV213RSQT2G?

A: Zero-Drift is a onsemi product series designation indicating advanced input offset voltage stability and temperature coefficient performance. This classification reflects the superior input offset voltage specification (5 µV) compared to the TSC213ICT (100 µV).

Q: Do both parts support the same supply voltage range?

A: Both parts support the maximum supply voltage of 26 V. The NCV213RSQT2G extends the minimum operating voltage to 2.2 V, while the TSC213ICT requires minimum 2.7 V. Applications operating above 2.7 V are compatible with both devices.

Q: What is the moisture sensitivity rating for both parts?

A: Both the TSC213ICT and NCV213RSQT2G carry MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture-related handling restrictions during storage or assembly.

Q: Are there any bandwidth or frequency response differences?

A: The TSC213ICT specifies -3dB bandwidth of 100 kHz, while the NCV213RSQT2G specifies 90 kHz. Both devices operate within comparable frequency response characteristics suitable for standard current sensing applications.
