INA210CIDCKR Equivalent & Substitute Parts

Part Overview

The INA210CIDCKR is a zero-drift current sense amplifier manufactured by Texas Instruments, designed for single-ended current measurement applications. This IC integrates a precision amplifier with low input offset voltage and operates across a wide supply voltage range of 2.7V to 26V. The device is housed in a 6-TSSOP (SC-70-6/SOT-363) surface mount package and is actively produced with full RoHS3 compliance.

Current sense amplifiers are essential components in power management, battery monitoring, load detection, and overcurrent protection circuits. Finding equivalent or substitute parts becomes necessary when managing supply chain constraints, optimizing cost structures, or accommodating design revisions while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the INA210CIDCKR is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package compatibility: 6-TSSOP, SC-88, or SOT-363 surface mount packages
• Supply voltage range: Minimum 2.7V, maximum 26V
• Operating temperature range: -40°C to 125°C
• Single-ended or rail-to-rail output configuration
• Active product status with current manufacturing support
• RoHS3 compliance and equivalent regulatory status

Identified Substitute Parts:

1. NCS210RSQT2G (onsemi) — Direct functional equivalent with enhanced performance characteristics
2. ZXCT210CDW-7 (Diodes Incorporated) — Manufacturer-recommended alternative with different sensing architecture

Both substitute parts meet the core package, voltage, temperature, and compliance requirements. However, they differ in specific electrical parameters and functional implementation, requiring detailed parameter comparison for application-specific selection.

Parameter Comparison

Engineering Selection Recommendations

NCS210RSQT2G (onsemi) — Primary Equivalent:

The NCS210RSQT2G is a direct functional equivalent offering superior electrical performance. It maintains identical input offset voltage (0.55 µV) while providing enhanced slew rate (1 V/µs vs. 0.4 V/µs) and wider bandwidth (40 kHz vs. 14 kHz). Supply current is reduced to 40 µA compared to 65 µA. The rail-to-rail output configuration provides greater flexibility in output signal conditioning. MSL rating of 1 (Unlimited) indicates superior moisture resistance compared to the INA210CIDCKR's MSL 2 rating. Both devices share identical package compatibility and operating temperature range. This part is suitable for direct substitution in applications where improved bandwidth and reduced power consumption are beneficial.

ZXCT210CDW-7 (Diodes Incorporated) — Alternative with Different Architecture:

The ZXCT210CDW-7 represents a different functional approach, implementing a current monitor with high/low-side sensing capability rather than a traditional current sense amplifier. It specifies ±0.5% accuracy and includes AEC-Q100 automotive qualification. This device is suitable for applications requiring automotive-grade reliability or where high/low-side sensing topology is advantageous. MSL rating of 1 (Unlimited) provides superior moisture handling. Package compatibility and supply voltage range are maintained. This part is appropriate for substitution in automotive applications or where current monitoring accuracy specification is critical.

Compliance and Regulatory Status:

All three parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification. The ZXCT210CDW-7 includes additional AEC-Q100 automotive qualification, making it suitable for automotive-grade applications.

Frequently Asked Questions (FAQ)

Q: Can NCS210RSQT2G be used as a direct replacement for INA210CIDCKR?

A: Yes. Both devices are housed in compatible 6-TSSOP/SC-88/SOT-363 packages, operate across the same supply voltage range (2.7V to 26V), and share identical operating temperature specifications (-40°C to 125°C). The NCS210RSQT2G offers enhanced performance with higher slew rate and bandwidth. Pin-level compatibility and functional equivalence are confirmed through package and circuit topology alignment.

Q: What are the key differences between NCS210RSQT2G and ZXCT210CDW-7?

A: The NCS210RSQT2G is a current sense amplifier with rail-to-rail output, while the ZXCT210CDW-7 is a current monitor with high/low-side sensing capability. The NCS210RSQT2G provides specified slew rate and bandwidth parameters; the ZXCT210CDW-7 specifies ±0.5% accuracy. The ZXCT210CDW-7 includes AEC-Q100 automotive qualification. Selection depends on whether traditional amplifier topology or current monitor architecture is required for the application.

Q: Are all three parts RoHS3 compliant?

A: Yes. INA210CIDCKR, NCS210RSQT2G, and ZXCT210CDW-7 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the significance of MSL rating differences?

A: MSL (Moisture Sensitivity Level) indicates moisture absorption characteristics during storage and handling. INA210CIDCKR carries MSL 2 (1 Year), requiring reflow within one year of opening the package. NCS210RSQT2G and ZXCT210CDW-7 both carry MSL 1 (Unlimited), indicating superior moisture resistance and no time-based reflow requirement. This affects long-term inventory management and handling procedures.

Q: Is ZXCT210CDW-7 suitable for automotive applications?

A: Yes. The ZXCT210CDW-7 includes AEC-Q100 automotive qualification, making it appropriate for automotive-grade applications. INA210CIDCKR and NCS210RSQT2G do not carry explicit automotive qualification in the provided specifications.

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

A: The supply voltage ranges are compatible for most applications. INA210CIDCKR and ZXCT210CDW-7 both specify 2.7V minimum. NCS210RSQT2G specifies 2.2V minimum, providing extended low-voltage operation capability. Maximum supply voltage is 26V for all three parts.

Q: What packaging options are available for these parts?

A: All three parts are available in 6-TSSOP, SC-88, and SOT-363 surface mount packages. These are equivalent package designations for the same physical form factor, ensuring PCB footprint compatibility across all three devices.
