Key Parameters

Substitute Part Grouping Explanation

The CS0305B is identified as a parametric equivalent within the CSXX05B series. Substitution eligibility is determined by the following criteria:

Matching Parameters:

• Manufacturer: CUI Devices (same manufacturer ensures design compatibility)
• Series: CSXX05B (same product family with identical electrical architecture)
• Sensor Type: Open Loop (identical sensing methodology)
• Measurement Type: AC (same application domain)
• Number of Channels: 1 (identical channel configuration)
• Output Type: Ratiometric, Voltage (identical output characteristics)
• Frequency Response: DC ~ 40kHz (identical bandwidth)
• Linearity: ±0.5% (identical linearity specification)
• Accuracy: ±2.2% (identical accuracy specification)
• Supply Voltage Range: 4.75V ~ 5.25V (identical supply requirements)
• Response Time: 7µs (identical response characteristics)
• Maximum Supply Current: 25mA (identical power consumption)
• Operating Temperature Range: -10°C ~ 75°C (identical thermal operating window)
• Polarization: Bidirectional (identical current direction capability)
• Mounting Type: Through Hole (identical mechanical mounting)
• Package Type: Module (identical form factor)
• RoHS Status: ROHS3 Compliant (identical compliance)
• REACH Status: REACH Unaffected (identical regulatory status)
• Product Status: Active (both parts in active production)

Differing Parameter:

• Current Sensing Range: CS2005B = 20A; CS0305B = 3A

The CS0305B operates with a reduced current sensing range of 3A compared to the 20A range of the CS2005B. This difference defines the substitution relationship as a lower-current-range alternative within the same product family.

Parameter Comparison

Engineering Selection Recommendations

Both the CS2005B and CS0305B are active production parts manufactured by CUI Devices with identical RoHS3 compliance and REACH unaffected regulatory status. Selection between these parts is determined by the maximum AC current measurement requirement of the application circuit.

The CS2005B is the appropriate selection for applications requiring measurement of AC currents up to 20A. The CS0305B is the appropriate selection for applications requiring measurement of AC currents up to 3A. Both parts share identical electrical performance characteristics including linearity, accuracy, frequency response, and supply voltage requirements, ensuring equivalent circuit behavior within their respective current measurement ranges.

The identical through-hole mounting type, module package configuration, and thermal operating window (-10°C to 75°C) ensure mechanical and environmental compatibility in equivalent circuit board designs.
