MCS1802GS-40-P Hall Effect Current Sensor Equivalent & Substitute Parts

Part Overview

The MCS1802GS-40-P is a 3.3V linear Hall-effect current sensor manufactured by Monolithic Power Systems Inc., designed for bidirectional AC/DC current measurement applications. This surface-mount device operates in the ±40A sensing range with ratiometric voltage output and is housed in an 8-SOIC package. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance are maintained across the component specification. Alternative part numbers within the same product family provide equivalent functionality for applications requiring component availability optimization or supply chain flexibility.

Parameter Comparison

Engineering Selection Recommendations

The MCS1802GS-40-P and MCS1802GS-40-Z are direct parametric equivalents manufactured by Monolithic Power Systems Inc. Both parts maintain identical electrical specifications, mechanical packaging, and regulatory compliance status. Selection between these parts is based on availability and supply chain considerations rather than technical performance differentiation.

Both parts are Active products with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), confirming suitability for standard manufacturing and storage environments. The 8-SOIC surface-mount package is consistent across both variants, ensuring PCB layout and assembly process compatibility.

Component selection should prioritize inventory availability and lead time requirements, as electrical and mechanical performance characteristics are fully equivalent between the MCS1802GS-40-P and MCS1802GS-40-Z.

Frequently Asked Questions (FAQ)

Q: Are MCS1802GS-40-P and MCS1802GS-40-Z electrically interchangeable?

A: Yes. Both parts are manufactured by Monolithic Power Systems Inc. and share identical electrical specifications including current sensing range (±40A), sensitivity (33mV/A), frequency response (100kHz), accuracy (±2.5%), and all other performance parameters.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts use the 8-SOIC (0.154", 3.90mm Width) surface-mount package with identical pinout and mechanical dimensions. No PCB layout modifications are required for substitution.

Q: What is the difference between the MCS1802GS-40-P and MCS1802GS-40-Z part numbers?

A: The part numbers differ only in the final suffix character (P versus Z). This designation typically indicates packaging or tape reel configuration differences, not functional or electrical differences. Both parts maintain identical electrical performance and package type specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both MCS1802GS-40-P and MCS1802GS-40-Z are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life and no special moisture control requirements during storage or handling.

Q: What is the operating temperature range for these current sensors?

A: Both parts operate across -40°C to 125°C junction temperature range, suitable for industrial and automotive applications requiring extended temperature performance.

Q: Can these Hall-effect sensors measure both AC and DC current?

A: Yes. Both parts are specified for AC/DC current measurement with bidirectional polarization, enabling measurement of current flow in either direction.

Q: What supply voltage is required for these sensors?

A: Both parts require a supply voltage between 3V and 3.6V, typical for 3.3V logic-level applications.
