Substitute Part Grouping Explanation

Substitute parts for the CS1512B are selected from the CSXX12B series based on identical electrical and mechanical parameters with the exception of current sensing range. All substitute parts maintain the following critical parameters:

Invariant Parameters (Must Match for Substitution):

• Sensor Type: Open Loop
• Measurement Type: AC
• Number of Channels: 1
• Output Type: Ratiometric, Voltage
• Frequency Range: DC ~ 40kHz
• Linearity: ±0.5%
• Accuracy: ±4.2%
• Supply Voltage: 11.4V ~ 12.6V
• Response Time: 3µs
• Maximum Supply Current: 25mA
• Operating Temperature Range: -10°C ~ 75°C
• Polarization: Bidirectional
• Mounting Type: Through Hole
• Package Type: Module
• Packaging Format: Tray
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Variable Parameter (Differentiates Substitutes):

• Current Sensing Range: 3A, 5A, 10A, or 15A

Substitution is valid when the application current requirement does not exceed the rated sensing range of the selected part. All substitute parts are manufactured by CUI Devices within the same product series and share identical mechanical mounting and electrical interface characteristics.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status with full ROHS3 compliance and REACH unaffected designation, ensuring regulatory consistency across the CSXX12B series. Selection between CS1512B, CS1012B, CS0512B, and CS0312B is determined solely by the maximum AC current to be measured in the application circuit.

For applications measuring currents up to 3A, the CS0312B provides the lowest current sensing range within the series. For applications measuring currents up to 5A, the CS0512B is appropriate. For applications measuring currents up to 10A, the CS1012B is appropriate. For applications measuring currents up to 15A, the CS1512B is appropriate.

All parts share identical electrical interface characteristics, mechanical mounting configuration, and environmental operating specifications. Substitution between parts within this series does not require circuit redesign or recalibration of measurement algorithms, provided the application current does not exceed the selected part's rated sensing range.

Frequently Asked Questions (FAQ)

Q: Can the CS1012B substitute for the CS1512B in an application measuring 12A?

A: No. The CS1012B has a maximum current sensing range of 10A. An application measuring 12A requires the CS1512B or a higher-rated part from a different series.

Q: Can the CS1512B substitute for the CS0512B in an application measuring 3A?

A: Yes. The CS1512B can measure currents up to 15A, which includes the 3A requirement. However, the CS0512B or CS0312B would provide more appropriate sensitivity for a 3A application within the same series.

Q: Are all substitute parts mechanically compatible with the same PCB footprint?

A: Yes. All parts in the CSXX12B series share identical Through Hole mounting type and Module package configuration, ensuring mechanical compatibility with the same PCB layout.

Q: Do substitute parts require different supply voltage?

A: No. All substitute parts operate within the identical supply voltage range of 11.4V ~ 12.6V.

Q: What is the primary difference between CS1512B and its substitutes?

A: The primary difference is the current sensing range. CS1512B measures up to 15A, CS1012B up to 10A, CS0512B up to 5A, and CS0312B up to 3A. All other electrical and mechanical parameters remain identical.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in Tray packaging format.

Q: Do substitute parts have the same response time?

A: Yes. All substitute parts have an identical response time of 3µs.

Q: Can I use a lower-rated part if my application current is below its maximum range?

A: Yes. A lower-rated part can be used if the application current does not exceed its rated sensing range. For example, CS0312B can be used in applications measuring up to 3A.
