MCS1806GS-3-05-Z Hall Effect Current Sensor Equivalent & Substitute Parts

Part Overview

The MCS1806GS-3-05-Z is an isolated Hall-effect current sensor manufactured by Monolithic Power Systems Inc., designed for AC/DC current measurement applications. This component operates as a differential, bidirectional sensor with a measurement range of ±5A and provides ratiometric voltage output. The device is currently in active production status and is widely used in power management, motor control, and industrial measurement circuits requiring galvanic isolation with 3KVRMS rating.

Substitute parts are identified when design requirements necessitate alternative packaging formats, inventory availability changes, or when equivalent electrical and mechanical specifications are required for production continuity.

Parameter Comparison

Engineering Selection Recommendations

Both MCS1806GS-3-05-Z and MCS1806GS-3-05-P are active production components from Monolithic Power Systems Inc. with identical electrical specifications, mechanical packaging, and regulatory compliance status. The parts differ only in packaging format designation (Z versus P suffix), which reflects different tape and reel configurations for automated assembly processes.

Selection between these parts is based on:

Production Line Compatibility: Verify that your pick-and-place equipment and feeder systems support the specific tape and reel format of the selected part number.

Supply Chain Availability: Current inventory levels show MCS1806GS-3-05-Z with 2830 units and MCS1806GS-3-05-P with 1468 units in stock. Selection may depend on procurement lead times and inventory requirements.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH Unaffected status, suitable for applications in regulated markets including automotive, industrial, and consumer electronics.

Functional Interchangeability: No circuit redesign or PCB layout modification is required when substituting between these part numbers. Pin configuration, electrical performance, and thermal characteristics are identical.

Frequently Asked Questions (FAQ)

Q: Can MCS1806GS-3-05-P be used as a direct replacement for MCS1806GS-3-05-Z in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The only difference is the tape and reel packaging format. No circuit modifications are required. Verify that your assembly equipment supports the specific reel format of the substitute part.

Q: What does the Z and P suffix designation indicate?

A: The Z and P suffixes indicate different tape and reel packaging configurations used for automated pick-and-place assembly. Both formats contain the same die and provide identical electrical performance.

Q: Are there any temperature or frequency limitations when using the substitute part?

A: No. Both parts operate identically across the full temperature range of -40°C to 125°C and support frequency response to 100kHz. All performance specifications are identical.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both MCS1806GS-3-05-Z and MCS1806GS-3-05-P are ROHS3 compliant, REACH Unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited).

Q: What is the 3KVRMS isolation rating?

A: The 3KVRMS specification indicates the galvanic isolation voltage rating between the primary current path and the secondary output signal. This isolation is maintained identically in both part numbers.

Q: Can these parts be used for both AC and DC current measurement?

A: Yes. Both parts are rated for AC/DC current measurement with bidirectional polarization, supporting measurement of current flowing in either direction with ±5A range.

Q: What is the significance of the 264mV/A sensitivity specification?

A: This ratiometric sensitivity means the output voltage changes by 264 millivolts for each ampere of measured current. This specification is identical in both substitute parts.

Q: Are there any supply voltage considerations when selecting between these parts?

A: No. Both parts require identical supply voltage of 3V to 3.6V and draw a maximum of 10.5mA. Supply circuit design remains unchanged between the two part numbers.
