CS2012U Current Sensor Equivalent & Substitute Parts

Part Overview

The CS2012U is an open-loop current sensor manufactured by CUI Devices, designed for AC current measurement applications. This unidirectional module provides ratiometric voltage output with a 20A sensing range and operates across a frequency spectrum of DC to 40kHz. The part is Active in product status and maintains full compliance with ROHS3 and REACH standards.

Substitute parts are identified when application requirements differ in current-sensing capacity while maintaining compatibility across all other electrical and mechanical parameters. The CS2012U operates within the CSXX12U series, which provides multiple current-sensing options with identical electrical characteristics, supply voltage specifications, and physical mounting configurations.

Engineering Selection Recommendations

All substitute parts within the CSXX12U series maintain Active product status and full compliance with ROHS3 and REACH regulatory requirements. Selection between CS0312U, CS0512U, CS1012U, and CS2012U is determined exclusively by application current-measurement requirements.

The CS2012U is appropriate for applications requiring 20A current sensing. The CS1012U provides equivalent functionality for 10A applications. The CS0512U serves 5A measurement requirements, and the CS0312U addresses 3A sensing applications.

All parts share identical electrical performance characteristics, including ±1.9% accuracy, ±0.5% linearity, 3µs response time, and DC to 40kHz frequency response. Supply voltage specifications, operating temperature ranges, and physical mounting configurations are uniform across the series.

Frequently Asked Questions (FAQ)

Q: Can CS0312U, CS0512U, or CS1012U be used as direct replacements for CS2012U?

A: These parts are functionally equivalent only when application current requirements are lower than 20A. CS0312U is suitable for 3A applications, CS0512U for 5A applications, and CS1012U for 10A applications. If the application requires 20A sensing, CS2012U is the appropriate selection.

Q: Are all parts in the CSXX12U series electrically compatible?

A: Yes. All parts share identical electrical specifications including output type (Ratiometric, Voltage), frequency response (DC ~ 40kHz), accuracy (±1.9%), linearity (±0.5%), response time (3µs), and supply voltage range (11.4V ~ 12.6V). Compatibility is determined by current-sensing capacity requirements.

Q: Do substitute parts require different mounting or PCB layout modifications?

A: No. All parts use Through Hole mounting type and Module package configuration. Physical form factors and mounting requirements are identical across the series.

Q: What is the difference between these parts and other CUI Devices current sensors?

A: The CSXX12U series is characterized by 12V supply voltage operation, open-loop sensing topology, unidirectional polarization, and single-channel configuration. These specifications define the series and distinguish it from other CUI Devices current sensor families.

Q: Are all substitute parts ROHS3 and REACH compliant?

A: Yes. All parts in the CSXX12U series are ROHS3 Compliant and REACH Unaffected, maintaining identical regulatory compliance status.

Q: What is the maximum supply current for all parts in this series?

A: The maximum supply current is 25mA across all parts in the CSXX12U series, including CS0312U, CS0512U, CS1012U, and CS2012U.

Q: Can these sensors measure both AC and DC current?

A: These sensors are specified for AC current measurement. The frequency range of DC ~ 40kHz indicates the operational bandwidth for signal processing.
