CS1505U Current Sensor Equivalent & Substitute Parts

Part Overview

The CS1505U is an open-loop current sensor manufactured by CUI Devices, designed for AC current measurement applications. This single-channel module provides ratiometric voltage output with a 15A sensing range and operates across a frequency spectrum from DC to 40kHz. The part is currently active in production with full RoHS3 compliance and REACH unaffected status. Alternative models within the CSXX05U series become necessary when application requirements specify different current sensing ranges, lower supply current budgets, or when specific inventory availability necessitates component substitution while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CS1505U are selected from the CSXX05U series based on strict electrical and mechanical parameter alignment. All substitute candidates share identical specifications across the following critical parameters: sensor type (open loop), output configuration (ratiometric voltage), frequency response (DC ~ 40kHz), linearity (±0.5%), accuracy (±4.2%), supply voltage range (4.75V ~ 5.25V), response time (7µs), maximum supply current (25mA), operating temperature range (-10°C ~ 75°C), polarization (unidirectional), mounting type (through hole), package type (module), packaging format (tray), product status (active), RoHS compliance (ROHS3), and REACH status (unaffected).

The primary differentiating parameter among substitute parts is the current sensing range. The CS1505U operates at 15A, while substitute models CS1005U and CS0505U provide 10A and 5A sensing ranges respectively. These alternatives maintain complete electrical and mechanical compatibility with the main part across all other specified parameters, enabling direct substitution when application requirements specify lower current measurement thresholds.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CS1505U, CS1005U, and CS0505U—maintain active production status with identical compliance certifications. Each part carries full RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment across all three options for applications subject to environmental and hazardous substance restrictions.

Selection between these parts depends exclusively on the maximum current measurement requirement of the application. The CS1505U accommodates measurements up to 15A, the CS1005U up to 10A, and the CS0505U up to 5A. All other electrical characteristics, mechanical specifications, and performance parameters remain constant across the series. Component selection should be based on the actual peak current that requires measurement within the application circuit.

Frequently Asked Questions (FAQ)

Q: Can CS1005U or CS0505U be used as direct replacements for CS1505U?

A: Direct replacement is possible only when the application's maximum current measurement requirement does not exceed the substitute part's sensing range. CS1005U supports measurements up to 10A, and CS0505U supports measurements up to 5A. If the application requires measurement of currents exceeding these thresholds, substitution is not appropriate.

Q: Are the electrical output characteristics identical across all three parts?

A: Yes. All three parts provide identical ratiometric voltage output, linearity (±0.5%), accuracy (±4.2%), frequency response (DC ~ 40kHz), response time (7µs), and supply voltage requirements (4.75V ~ 5.25V). The output signal conditioning and interface characteristics are equivalent.

Q: Do these parts share the same physical footprint and mounting requirements?

A: Yes. All three parts use through-hole mounting, module package type, and tray packaging format. PCB layout and mechanical integration are identical across CS1505U, CS1005U, and CS0505U.

Q: What compliance certifications apply to all substitute parts?

A: All three parts carry ROHS3 compliance and REACH unaffected status. No additional compliance verification is required when substituting between these parts in applications subject to these regulatory frameworks.

Q: How does current sensing range affect measurement accuracy?

A: Linearity and accuracy specifications remain constant at ±0.5% and ±4.2% respectively across all three parts. The sensing range determines the maximum current that can be measured, but does not alter the accuracy characteristics within each part's operating range.

Q: Are there inventory considerations for part selection?

A: Inventory availability varies by part number. CS1505U has 926 units in stock, CS1005U has 883 units, and CS0505U has 904 units. Availability should be confirmed at the time of procurement.
