TSC210ICT Current Sense Amplifier Equivalent & Substitute Parts

Part Overview

The TSC210ICT 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/SOT-363) surface mount package. The device is classified as Active product status with full RoHS3 compliance and 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, inventory availability, or when design specifications allow for enhanced performance characteristics within the same package footprint and electrical operating range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSC210ICT with equivalent parts is determined by strict alignment of the following electrical and mechanical parameters:

Package Compatibility: The substitute part must utilize the same 6-TSSOP/SC-88/SOT-363 surface mount package to ensure direct PCB footprint compatibility without layout modifications.

Supply Voltage Range: The substitute must operate across the full 2.7 V to 26 V supply voltage span. Parts with narrower supply ranges are not acceptable substitutes.

Amplifier Classification: The substitute must be classified as a current sense amplifier with a single circuit configuration to maintain functional equivalence.

Operating Temperature: The substitute must support the full -40°C to 125°C operating temperature range.

Compliance Standards: The substitute must maintain RoHS3 compliance and REACH unaffected status to satisfy regulatory requirements.

Mounting Technology: Surface mount technology is required for direct substitution without assembly process changes.

The NCS210RSQT2G from onsemi meets all mandatory substitution criteria. While this part exhibits enhanced electrical performance characteristics (improved slew rate, bandwidth, input offset voltage, and supply current), these represent performance improvements rather than deviations from the substitution parameters, making it a valid direct substitute.

Engineering Selection Recommendations

TSC210ICT Selection: Retain the TSC210ICT when existing designs are validated and qualified for this specific part number, or when supply chain availability from STMicroelectronics is confirmed. This part maintains Active product status with established manufacturing continuity.

NCS210RSQT2G Selection: The NCS210RSQT2G from onsemi is a direct substitute suitable for new designs or when addressing supply constraints. Both parts maintain identical Active product status and full regulatory compliance (RoHS3, REACH unaffected). The onsemi part offers enhanced electrical performance including superior input offset voltage accuracy (0.55 µV versus 35 µV), increased bandwidth (40 kHz versus 25 kHz), and reduced supply current consumption (40 µA versus 65 µA). The minimum supply voltage specification of the NCS210RSQT2G (2.2 V) provides extended low-voltage operation capability compared to the TSC210ICT (2.7 V minimum).

Interchangeability: Both parts are mechanically and electrically interchangeable within the 6-TSSOP/SC-88/SOT-363 package footprint. No PCB layout modifications are required for substitution. Both devices support the full -40°C to 125°C industrial temperature range and maintain unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can the NCS210RSQT2G directly replace the TSC210ICT on existing PCBs?

A: Yes. Both parts utilize identical 6-TSSOP/SC-88/SOT-363 surface mount package geometry and pinout. No PCB layout modifications are required. The parts are pin-compatible and functionally equivalent within the specified electrical operating parameters.

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

A: The NCS210RSQT2G exhibits superior performance in four areas: input offset voltage (0.55 µV versus 35 µV), slew rate (1 V/µs versus 0.2 V/µs), -3dB bandwidth (40 kHz versus 25 kHz), and supply current (40 µA versus 65 µA). The NCS210RSQT2G also supports operation at lower minimum supply voltage (2.2 V versus 2.7 V). These represent performance enhancements rather than functional deviations.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the TSC210ICT and NCS210RSQT2G are RoHS3 compliant with REACH unaffected status, meeting current regulatory requirements for electronic components.

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

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture-related handling restrictions during storage, transport, or assembly processes.

Q: Can I use the NCS210RSQT2G in applications requiring the exact electrical specifications of the TSC210ICT?

A: The NCS210RSQT2G meets or exceeds all electrical specifications of the TSC210ICT. Applications designed for the TSC210ICT will function with the NCS210RSQT2G. The enhanced performance characteristics of the onsemi part do not create incompatibility with existing designs.

Q: Are there any temperature range limitations when substituting between these parts?

A: No. Both parts operate across the identical -40°C to 125°C temperature range, ensuring full compatibility across all industrial and commercial operating conditions.

Q: What supply voltage range must be supported for substitution?

A: Both parts support 26 V maximum supply voltage. The TSC210ICT requires minimum 2.7 V, while the NCS210RSQT2G operates at minimum 2.2 V. Designs operating between 2.2 V and 2.7 V can only use the NCS210RSQT2G. Designs operating above 2.7 V are compatible with both parts.
