MCS1800GS-25-Z Equivalent & Substitute Parts

Part Overview

The MCS1800GS-25-Z 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 ±25A sensing range with ratiometric voltage output and is packaged in an 8-SOIC form factor. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance are maintained across the specified parameter set. Alternative sourcing becomes necessary due to inventory availability, supply chain considerations, or procurement requirements while maintaining identical functional specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the MCS1800GS-25-Z and MCS1800GS-25-P are Active products from Monolithic Power Systems Inc. with identical electrical specifications, mechanical packaging, and regulatory compliance profiles. The parts differ only in packaging format designation (Z versus P suffix), which reflects tape and reel configuration variations within the same product family.

Selection between these parts is based on:

Inventory Availability: MCS1800GS-25-Z maintains 2993 pieces in stock, while MCS1800GS-25-P maintains 1998 pieces in stock.

Compliance Status: Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity rating, ensuring equivalent regulatory acceptance across applications.

Functional Equivalence: All electrical parameters, thermal specifications, and performance characteristics are identical, enabling direct substitution in circuit designs without modification to PCB layout, schematic, or firmware.

Frequently Asked Questions (FAQ)

Q: Can MCS1800GS-25-P be used as a direct replacement for MCS1800GS-25-Z in existing designs?

A: Yes. Both parts are parametrically equivalent across all electrical, mechanical, and thermal specifications. No circuit modifications, PCB layout changes, or firmware adjustments are required for substitution.

Q: What is the difference between the Z and P suffix designations?

A: The suffix designations reflect packaging format variations within the same product family. Both parts are supplied in tape and reel format and use identical 8-SOIC package geometry. The functional performance and pin configuration are identical.

Q: Are there any temperature or operating condition differences between these parts?

A: No. Both parts operate across the identical temperature range of -40°C to 125°C (TJ) with identical frequency response, response time, and accuracy specifications.

Q: Do both parts meet the same regulatory compliance requirements?

A: Yes. Both MCS1800GS-25-Z and MCS1800GS-25-P are ROHS3 compliant, REACH unaffected, and carry MSL 1 moisture sensitivity rating. They are equivalent for regulatory and environmental compliance purposes.

Q: What is the current sensing accuracy for both parts?

A: Both parts provide ±3% accuracy with ±0.5% linearity across the ±25A sensing range at 55mV/A sensitivity.

Q: Can these parts be used interchangeably in production assembly?

A: Yes. Identical package geometry (8-SOIC, 0.154" width, 3.90mm), surface-mount technology, and pin configuration enable interchangeable use in production assembly processes without tooling or process modifications.
