CS1505B Current Sensor Equivalent & Substitute Parts

Part Overview

The CS1505B is an active current sensor manufactured by CUI Devices, designed for open-loop bidirectional current measurement applications. This module operates at 15A sensing capacity with ratiometric voltage output and is compliant with ROHS3 and REACH standards. The product maintains active status in the manufacturer's portfolio. Substitute parts are identified when equivalent electrical and mechanical parameters align with application requirements, enabling component selection flexibility for procurement, inventory management, or design optimization scenarios.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CS1505B is determined by alignment across the following critical parameters:

Series Compatibility: Both the main part and substitute must belong to the CSXX05B series, ensuring mechanical and electrical interface consistency.

Sensor Architecture: Open-loop topology must be maintained to preserve signal conditioning characteristics and output behavior.

Output Configuration: Ratiometric voltage output must be identical to ensure direct compatibility with existing signal processing circuits.

Frequency Response: The DC ~ 40kHz bandwidth specification must be matched to support the intended measurement frequency range.

Accuracy and Linearity: Specifications of ±2.2% accuracy and ±0.5% linearity must be preserved for measurement reliability.

Supply Voltage Range: The 4.75V ~ 5.25V supply specification must be maintained for power distribution compatibility.

Response Time: The 7µs response time specification must be consistent to preserve dynamic measurement performance.

Polarization: Bidirectional measurement capability must be retained.

Mounting and Packaging: Through-hole mounting and module package type must remain unchanged.

Regulatory Compliance: ROHS3 and REACH status must be equivalent.

The CS0305B qualifies as a parametric equivalent based on these criteria, with the primary distinction being the current-sensing range of 3A versus the 15A specification of the CS1505B.

Parameter Comparison

Engineering Selection Recommendations

Both the CS1505B and CS0305B maintain active product status with CUI Devices and carry equivalent regulatory compliance certifications (ROHS3 Compliant, REACH Unaffected). Selection between these parts is determined by the maximum current measurement requirement of the application.

The CS1505B is specified for applications requiring measurement of currents up to 15A. The CS0305B is specified for applications requiring measurement of currents up to 3A. Both parts share identical electrical characteristics across frequency response, accuracy, linearity, supply voltage, response time, and output configuration.

Component selection must be based on the actual current range present in the target application. Selecting a part with insufficient current-sensing capacity will result in signal saturation and measurement error. Selecting a part with excess current-sensing capacity will result in reduced measurement resolution within the application's actual current range.

Frequently Asked Questions (FAQ)

Q: Can the CS0305B substitute for the CS1505B in all applications?

A: The CS0305B is electrically and mechanically compatible with the CS1505B across all parameters except current-sensing range. Substitution is valid only for applications where the maximum current does not exceed 3A. Applications requiring measurement of currents between 3A and 15A require the CS1505B.

Q: What is the primary difference between these two parts?

A: The current-sensing range differs: CS1505B measures up to 15A, while CS0305B measures up to 3A. All other electrical specifications, including output type, frequency response, accuracy, linearity, supply voltage, response time, and operating temperature, are identical.

Q: Are the mounting footprints identical?

A: Both parts feature through-hole mounting in module package configuration. Mechanical compatibility is maintained across the series.

Q: Do both parts require the same supply voltage?

A: Yes. Both the CS1505B and CS0305B operate with a supply voltage range of 4.75V ~ 5.25V and draw a maximum of 25mA.

Q: What is the frequency response capability of these sensors?

A: Both parts support DC ~ 40kHz frequency response, enabling measurement of AC and DC currents within this bandwidth.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical regulatory status: ROHS3 Compliant and REACH Unaffected.

Q: What is the response time for both sensors?

A: Both the CS1505B and CS0305B have a response time of 7µs, ensuring equivalent dynamic measurement performance.
