CS0512U Current Sensor Equivalent & Substitute Parts

Part Overview

The CS0512U is an active current sensor manufactured by CUI Devices designed for AC current measurement applications. This open-loop, unidirectional current sensor module provides ratiometric voltage output with a 5A sensing range and operates across a frequency spectrum from DC to 40kHz. The device is classified as Active product status and maintains full compliance with ROHS3 and REACH standards. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, allowing for component interchangeability within specified operational constraints.

Substitute Part Grouping Explanation

Substitute parts for the CS0512U are identified based on strict alignment of electrical and mechanical parameters within the CSXX12U series. The primary substitution criterion is membership within the same product series, which ensures compatibility with identical mechanical interfaces, electrical output characteristics, and operational specifications.

The CS0312U qualifies as a parametric equivalent based on the following matching parameters:

• Same manufacturer (CUI Devices)
• Same product series (CSXX12U)
• Identical sensor type (Open Loop)
• Identical number of channels (1)
• Identical output type (Ratiometric, Voltage)
• Identical frequency range (DC ~ 40kHz)
• Identical linearity specification (±0.5%)
• Identical accuracy specification (±1.9%)
• Identical supply voltage range (11.4V ~ 12.6V)
• Identical response time (3µs)
• Identical maximum supply current (25mA)
• Identical operating temperature range (-10°C ~ 75°C)
• Identical polarization (Unidirectional)
• Identical mounting type (Through Hole)
• Identical package type (Module)
• Identical RoHS and REACH compliance status

The primary difference between the main part and substitute is the current sensing range: CS0512U operates at 5A while CS0312U operates at 3A. This parameter difference defines the substitution boundary and determines application suitability.

Parameter Comparison

Engineering Selection Recommendations

Both the CS0512U and CS0312U maintain Active product status and full compliance with ROHS3 and REACH regulatory requirements. Component selection between these parts is determined by the maximum current measurement requirement of the application circuit.

The CS0512U is the appropriate selection for applications requiring current sensing up to 5A. The CS0312U is the appropriate selection for applications requiring current sensing up to 3A. Both devices provide identical electrical performance characteristics, mechanical interfaces, and regulatory compliance within their respective current measurement ranges.

Selection of either part is valid from a compliance and certification standpoint. The determining factor is whether the application circuit current does not exceed the specified sensing range of the selected device.

Frequently Asked Questions (FAQ)

Q: Can the CS0312U be used as a direct replacement for the CS0512U?

A: The CS0312U shares identical electrical and mechanical specifications with the CS0512U except for the current sensing range. The CS0312U is suitable only for applications where the measured current does not exceed 3A. If the application requires measurement of currents between 3A and 5A, the CS0512U must be used.

Q: Are the mounting interfaces identical between CS0512U and CS0312U?

A: Yes. Both devices use Through Hole mounting type and Module package configuration. The mechanical interfaces are identical.

Q: Do both parts operate with the same supply voltage?

A: Yes. Both the CS0512U and CS0312U operate with a supply voltage range of 11.4V to 12.6V.

Q: What is the primary difference between these two current sensor modules?

A: The primary difference is the current sensing range. The CS0512U measures currents up to 5A, while the CS0312U measures currents up to 3A. All other electrical characteristics, including output type, frequency response, accuracy, linearity, and response time, are identical.

Q: Are both parts compliant with environmental and regulatory standards?

A: Yes. Both the CS0512U and CS0312U are ROHS3 Compliant and REACH Unaffected.

Q: What output signal type do these sensors provide?

A: Both devices provide ratiometric voltage output, which scales proportionally with the measured current within their respective sensing ranges.

Q: Is the response time the same for both sensors?

A: Yes. Both the CS0512U and CS0312U have a response time of 3µs.
