MP163CGS-33-Z Equivalent & Substitute Parts

Part Overview

The MP163CGS-33-Z is an offline switch IC manufactured by Monolithic Power Systems Inc., designed for power management applications requiring multiple converter topologies. This PMIC operates as a non-isolated offline switch supporting Boost, Buck, Buck-Boost, and Flyback converter configurations at 28kHz switching frequency. The device is currently in active production status with 1126 units in stock. Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or equivalent functional performance across the MP163 base product family.

Substitute Part Grouping Explanation

The MP163CGS-33-Z shares parametric equivalence with three substitute parts within the MP163 base product family: MP163AGS-33-Z, MP163BGS-33-Z, and MP163CGS-5-Z. All four parts maintain identical electrical and mechanical specifications across the following critical parameters:

Voltage ratings (700V breakdown, 5.4V ~ 6V supply, 5.3V startup), switching frequency (28kHz), power capacity (4W), supported topologies (Boost, Buck, Buck-Boost, Flyback), package configuration (8-SOIC-7B with 7 leads), fault protection features (Current Limiting, Over Load, Short Circuit), control features (EN, Soft Start), operating temperature range (-40°C ~ 125°C), and compliance certifications (ROHS3, REACH Unaffected).

All substitute parts are manufactured by Monolithic Power Systems Inc., supplied in Tape & Reel packaging, and maintain active product status. The substitution relationship is bidirectional across all four part numbers, indicating full parametric compatibility for circuit design and application requirements.

Parameter Comparison

Engineering Selection Recommendations

All four parts—MP163CGS-33-Z, MP163AGS-33-Z, MP163BGS-33-Z, and MP163CGS-5-Z—are functionally equivalent for offline switch applications requiring Boost, Buck, Buck-Boost, or Flyback converter topologies. Each part maintains active product status with full ROHS3 compliance and REACH unaffected certification, confirming regulatory alignment for industrial and commercial applications.

Selection between these parts should be based on inventory availability and supply chain requirements. MP163AGS-33-Z offers the highest inventory level at 8810 units, followed by MP163CGS-5-Z at 6150 units. MP163CGS-33-Z maintains 1126 units in stock, while MP163BGS-33-Z has the lowest availability at 629 units. All parts are supplied in identical 8-SOIC-7B packaging with Surface Mount configuration, ensuring direct PCB layout compatibility without design modification.

Frequently Asked Questions (FAQ)

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

A: Yes. All four parts share identical electrical specifications, package configuration, and functional capabilities. Direct substitution is supported without circuit design changes or PCB layout modifications.

Q: Are there differences in switching frequency or power capacity between these parts?

A: No. All substitute parts operate at 28kHz switching frequency with 4W power capacity. Voltage ratings, topology support, and fault protection features are identical across all four part numbers.

Q: What is the significance of the different part number suffixes (AGS, BGS, CGS)?

A: The suffixes represent different product variants within the MP163 base product family. Despite these designations, all variants maintain parametric equivalence for the specifications provided in this reference.

Q: Are all parts available in the same packaging format?

A: Yes. All four parts are supplied in 8-SOIC-7B packaging with Tape & Reel delivery, ensuring identical PCB footprint and assembly compatibility.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All parts are ROHS3 compliant with REACH unaffected status. Moisture Sensitivity Level is 2 (1 Year) across all variants, and all maintain active product status.

Q: Which part should be selected based on availability?

A: MP163AGS-33-Z provides the highest inventory at 8810 units. MP163CGS-5-Z offers 6150 units. Selection should align with supply chain lead time and project delivery requirements.
