CS1512U Current Sensor Equivalent & Substitute Parts

Part Overview

The CS1512U is an active, open-loop current sensor manufactured by CUI Devices, designed for AC current measurement applications. This 15A unidirectional module operates within the CSXX12U series and delivers ratiometric voltage output with ±1.9% accuracy across a DC to 40kHz frequency range. The part is ROHS3 compliant and REACH unaffected, confirming its suitability for modern electronic applications. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, allowing for component interchangeability based on current-sensing capacity and operational specifications.

Substitute Part Grouping Explanation

Substitute parts for the CS1512U are identified within the CSXX12U series based on electrical and mechanical parameter alignment. All substitute candidates share identical specifications across sensor type (open loop), output configuration (ratiometric voltage), frequency response (DC ~ 40kHz), linearity (±0.5%), accuracy (±1.9%), supply voltage range (11.4V ~ 12.6V), response time (3µs), maximum supply current (25mA), operating temperature range (-10°C ~ 75°C), polarization (unidirectional), mounting type (through hole), package type (module), and compliance certifications (ROHS3, REACH unaffected).

The primary differentiating parameter is current-sensing capacity. Substitute parts are available in lower current ratings: CS0312U (3A), CS0512U (5A), and CS1012U (10A). These alternatives are suitable for applications where the measured current does not exceed the substitute part's rated sensing capacity. Selection of a substitute part must ensure that the application's maximum current requirement does not exceed the chosen part's current-sensing specification.

Engineering Selection Recommendations

All substitute parts within the CSXX12U series maintain active product status and full compliance with ROHS3 and REACH regulations. Selection between CS1512U and its substitutes is determined by application current requirements:

CS1512U is selected for applications requiring current measurement up to 15A.

CS1012U is selected for applications requiring current measurement up to 10A.

CS0512U is selected for applications requiring current measurement up to 5A.

CS0312U is selected for applications requiring current measurement up to 3A.

All parts deliver identical electrical performance characteristics including ±1.9% accuracy, ±0.5% linearity, 3µs response time, and DC to 40kHz frequency response. Substitution is valid when the application's maximum measured current does not exceed the substitute part's current-sensing rating. Through-hole mounting and module packaging are consistent across all alternatives, ensuring mechanical compatibility in existing circuit board designs.

Frequently Asked Questions (FAQ)

Q: Can CS1012U replace CS1512U in an application?

A: CS1012U can replace CS1512U only if the application's maximum measured current does not exceed 10A. Both parts share identical electrical specifications, output characteristics, and compliance certifications. If the application requires measurement of currents exceeding 10A, CS1012U is not suitable.

Q: Are all substitute parts mechanically compatible with CS1512U?

A: Yes. All substitute parts within the CSXX12U series share identical mounting type (through hole), package type (module), and packaging format (tray). Direct mechanical substitution is supported without circuit board redesign.

Q: What is the primary difference between CS1512U and CS0312U?

A: The primary difference is current-sensing capacity. CS1512U measures up to 15A, while CS0312U measures up to 3A. All other electrical parameters, including accuracy, linearity, frequency response, supply voltage, response time, and operating temperature range, are identical.

Q: Do all parts in this series require the same supply voltage?

A: Yes. All parts in the CSXX12U series require a supply voltage between 11.4V and 12.6V. Supply voltage compatibility is consistent across CS1512U, CS1012U, CS0512U, and CS0312U.

Q: Are there any compliance differences between substitute parts?

A: No. All substitute parts are ROHS3 compliant and REACH unaffected. Regulatory compliance is uniform across the entire CSXX12U series.

Q: Can a lower-rated part be used in place of CS1512U for cost reduction?

A: A lower-rated substitute part can be used only if the application's maximum measured current does not exceed that part's rating. Using an undersized current sensor for cost reduction without verifying current requirements creates risk of measurement error or component failure.

Q: What is the response time for all parts in this series?

A: All parts in the CSXX12U series, including CS1512U and its substitutes, have a response time of 3µs. Response time is identical across all current ratings.
