MP163CGS-5 Equivalent & Substitute Parts

Part Overview

The MP163CGS-5 is a 700V non-isolated offline power converter from Monolithic Power Systems Inc., designed for boost, buck, buck-boost, and flyback topologies operating at 28kHz switching frequency. This PMIC delivers 4W output power with integrated current limiting, overload, and short circuit protection. The device is Active status and ROHS3 compliant, making it suitable for industrial and consumer offline power supply applications. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in circuit designs without topology or performance modification.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts—MP163AGS-33, MP163BGS-33, and MP163CGS-33—are parametrically equivalent to MP163CGS-5 and maintain Active product status. Each part is ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and consumer applications. Selection among these parts may be based on inventory availability and lead time considerations, as all electrical and mechanical specifications are identical. The 8-SOIC-7B package ensures direct PCB compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can MP163AGS-33, MP163BGS-33, or MP163CGS-33 be used as direct replacements for MP163CGS-5?

A: Yes. All substitute parts share identical electrical parameters including 700V breakdown voltage, 28kHz switching frequency, 4W power rating, and 5.4V–6V supply voltage range. Package type, pin configuration, and fault protection features are also identical, enabling direct substitution without circuit redesign.

Q: Are there differences in topology support between the main part and substitutes?

A: No. All parts support the same topologies: boost, buck, buck-boost, and flyback configurations.

Q: What is the significance of the part number suffix (CGS-5 vs. AGS-33, BGS-33, CGS-33)?

A: The suffix indicates internal device variants within the MP163 base product family. Electrical and mechanical parameters remain equivalent across all variants listed, ensuring functional interchangeability.

Q: Do all parts meet the same compliance standards?

A: Yes. All parts are ROHS3 compliant with MSL rating of 2 (1 Year) and REACH unaffected status.

Q: Is the 8-SOIC-7B package identical across all parts?

A: Yes. All parts use the 8-SOIC package with 0.154" width and 7 leads, ensuring identical PCB footprint and mounting requirements.

Q: Can these parts be used in applications requiring non-isolated power conversion?

A: Yes. All parts are specified as non-isolated converters, suitable for applications where isolation is not required.
