CS20150B Current Sensor Equivalent & Substitute Parts

Part Overview

The CS20150B is an active current sensor manufactured by CUI Devices designed for open-loop bidirectional current measurement applications. This module operates across a 20A sensing range with ratiometric voltage output, suitable for AC measurement environments. The part maintains Active product status with full ROHS3 compliance and REACH unaffected classification. Substitute parts are identified when application requirements permit operation within alternative current-sensing specifications while maintaining compatibility across core electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitute parts within the CSXX150B series maintain identical electrical performance characteristics across frequency response, linearity, accuracy, supply voltage, response time, and supply current specifications. The primary differentiating parameter is the current-sensing range. The CS10150B operates at a 10A sensing specification compared to the 20A specification of the CS20150B. Both parts share identical sensor topology (open loop), output configuration (ratiometric voltage), channel count (1), polarization (bidirectional), mounting methodology (through hole), and thermal operating envelope. Substitution is valid when application current requirements do not exceed the 10A maximum sensing threshold of the CS10150B while maintaining all other system-level electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

Both CS20150B and CS10150B maintain Active product status with equivalent regulatory compliance. Selection between these parts is determined by application current-measurement requirements. The CS20150B accommodates measurement scenarios requiring full 20A sensing capability. The CS10150B is suitable for applications where measured current does not exceed 10A. Both parts deliver identical electrical performance in frequency response, signal accuracy, linearity, and temporal response characteristics. Compliance certifications (ROHS3, REACH unaffected) are equivalent across both options. Through-hole mounting and module packaging are consistent, ensuring mechanical compatibility within existing PCB designs. Supply voltage requirements and operating temperature ranges are identical, eliminating thermal or power-supply redesign considerations during substitution.

Frequently Asked Questions (FAQ)

Q: Can CS10150B replace CS20150B in all applications?

A: CS10150B substitution is valid only when the maximum measured current does not exceed 10A. All other electrical and mechanical parameters are identical. Applications requiring measurement of currents between 10A and 20A require the CS20150B.

Q: Are the output signal characteristics identical between CS20150B and CS10150B?

A: Yes. Both parts provide ratiometric voltage output with identical linearity (±0.5%), accuracy (±2.4%), frequency response (DC ~ 40kHz), and response time (3µs). Output signal conditioning and interface requirements are equivalent.

Q: Do these parts require different PCB layouts or mounting considerations?

A: No. Both parts use identical through-hole mounting methodology and module packaging. PCB footprints, mounting hole patterns, and mechanical envelope are compatible. No layout modifications are required during substitution.

Q: Are supply voltage and power consumption requirements the same?

A: Yes. Both CS20150B and CS10150B operate from 14.25V to 15.75V supply voltage with maximum supply current of 25mA. Power supply specifications and filtering requirements are identical.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -10°C to 75°C. Thermal management and environmental specifications are equivalent.

Q: Are regulatory compliance certifications identical?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected. No compliance-related design changes are required during substitution.

Q: How does the 10A versus 20A sensing specification affect measurement accuracy?

A: Accuracy specification (±2.4%) and linearity (±0.5%) are identical for both parts. The sensing range difference affects the full-scale output voltage mapping but does not alter measurement accuracy within each part's specified current range.
