INA210CIDCKT Equivalent & Substitute Parts

Part Overview

The INA210CIDCKT is a zero-drift current sense amplifier manufactured by Texas Instruments, designed for single-ended current measurement applications. This IC integrates one sensing circuit in a compact 6-TSSOP (SC-70-6/SOT-363) surface mount package and operates across a wide supply voltage range of 2.7 V to 26 V. The device is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameter specifications for this current sense amplifier category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the INA210CIDCKT is determined by strict alignment with the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 6-TSSOP/SC-88/SOT-363 surface mount package to ensure mechanical and electrical compatibility with existing PCB layouts.

Supply Voltage Range: The substitute must operate within or encompass the 2.7 V to 26 V supply voltage specification. A substitute with a lower minimum supply voltage (2.2 V) remains compatible as it covers the required operating range.

Circuit Configuration: The substitute must maintain a single-circuit configuration with current sense amplifier functionality.

Temperature Range: Operating temperature range of -40°C to 125°C must be met or exceeded.

Compliance Standards: Both parts must maintain RoHS3 compliance and REACH unaffected status for regulatory equivalence.

Output Characteristics: While the main part specifies single-ended output, a rail-to-rail output substitute remains functionally compatible for current sensing applications, as rail-to-rail output capability encompasses single-ended operation within the same supply voltage envelope.

The NCS210RSQT2G from onsemi meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: The INA210CIDCKT remains the primary choice when Texas Instruments supply chain availability is confirmed and existing design validation has been completed with this specific part number.

Substitute Selection: The NCS210RSQT2G is a qualified substitute when INA210CIDCKT availability is constrained. Both parts maintain Active product status, ensuring long-term supply continuity and manufacturing support. Both devices carry identical RoHS3 compliance and REACH unaffected certifications, meeting regulatory requirements for equivalent component substitution.

Compliance Equivalence: Both parts share identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications, confirming export and tariff equivalence.

Moisture Handling: The NCS210RSQT2G offers superior moisture sensitivity performance (MSL 1, Unlimited shelf life) compared to the INA210CIDCKT (MSL 2, 1 Year), providing extended storage capability without baking requirements.

Performance Characteristics: The NCS210RSQT2G demonstrates enhanced electrical performance with higher slew rate (1 V/µs vs. 0.4 V/µs) and wider bandwidth (40 kHz vs. 14 kHz), while maintaining identical input offset voltage (0.55 µV). Lower supply current (40 µA vs. 65 µA) in the substitute reduces power consumption. The lower minimum supply voltage (2.2 V vs. 2.7 V) extends operational range in low-voltage applications.

Frequently Asked Questions (FAQ)

Q: Can the NCS210RSQT2G directly replace the INA210CIDCKT in existing designs?

A: Yes. Both parts use identical 6-TSSOP/SC-88/SOT-363 surface mount packages, operate across overlapping supply voltage ranges (2.2 V to 26 V for NCS210RSQT2G encompasses 2.7 V to 26 V for INA210CIDCKT), and maintain identical input offset voltage specifications. Pin-to-pin compatibility is confirmed for direct PCB substitution.

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

A: The NCS210RSQT2G provides higher slew rate (1 V/µs vs. 0.4 V/µs), wider bandwidth (40 kHz vs. 14 kHz), and lower supply current (40 µA vs. 65 µA). Input offset voltage remains identical at 0.55 µV. These differences represent performance enhancements in the substitute part.

Q: Are both parts suitable for the same temperature range applications?

A: Yes. Both parts operate across -40°C to 125°C, meeting identical temperature specifications for industrial and automotive applications.

Q: What is the significance of the different output types (Single-Ended vs. Rail-to-Rail)?

A: The NCS210RSQT2G rail-to-rail output capability is a superset of single-ended output functionality. Rail-to-rail output can operate as single-ended within the same supply voltage envelope, making it functionally compatible for current sensing applications designed for the INA210CIDCKT.

Q: How do the moisture sensitivity levels affect component handling?

A: The INA210CIDCKT (MSL 2) requires baking after one year of storage at standard humidity conditions. The NCS210RSQT2G (MSL 1) has unlimited shelf life without moisture-related storage constraints, reducing handling complexity and cost in high-volume manufacturing environments.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both parts are RoHS3 compliant and REACH unaffected, meeting current EU and international regulatory requirements. Both share identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications for export and tariff purposes.

Q: Which part should be selected for new design implementations?

A: For new designs, the NCS210RSQT2G is recommended based on superior performance characteristics (higher bandwidth, lower power consumption), extended moisture sensitivity rating, and equivalent regulatory compliance. The INA210CIDCKT remains valid for designs with existing validation or specific Texas Instruments ecosystem requirements.
