Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP163BGS-33-Z are identified based on strict parameter equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

Voltage ratings (Breakdown: 700V, Supply: 5.4V ~ 6V, Start Up: 5.3V), Switching frequency (28kHz), Power rating (4W), Topology support (Boost, Buck, Buck-Boost, Flyback), Fault protection features (Current Limiting, Over Load, Short Circuit), Control features (EN, Soft Start), Operating temperature range (-40°C ~ 125°C), Package type (8-SOIC-7B), and Compliance certifications (ROHS3, REACH Unaffected).

All substitute parts listed maintain identical specifications across these parameters, ensuring functional and electrical equivalence for direct circuit replacement.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts (MP163AGS-33-Z, MP163CGS-33-Z, MP163CGS-5-Z) maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment with modern manufacturing standards. Selection among equivalent parts may be based on inventory availability and lead time considerations, as all parts are functionally identical across electrical specifications, thermal performance, and protection features.

The MP163AGS-33-Z offers 8810 units in stock, MP163CGS-33-Z provides 1126 units, and MP163CGS-5-Z supplies 6150 units, compared to 629 units of the primary MP163BGS-33-Z part. All parts carry identical REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can MP163AGS-33-Z replace MP163BGS-33-Z in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters including voltage ratings, switching frequency, power rating, topology support, protection features, and package type. Direct substitution is supported without circuit modification.

Q: What distinguishes the different part number variants (BGS, AGS, CGS)?

A: The variants represent different manufacturing batches or date codes from Monolithic Power Systems Inc. All variants maintain identical electrical specifications, thermal characteristics, and functional capabilities as defined in the parameter comparison table.

Q: Are all substitute parts suitable for the same PCB layout?

A: Yes. All substitute parts use the identical 8-SOIC-7B package with 0.154" width and 7 leads, ensuring footprint compatibility and direct PCB placement without layout modifications.

Q: What is the significance of the "-33-Z" and "-5-Z" suffixes?

A: These suffixes indicate different tape reel configurations or packaging specifications from the manufacturer. Electrical and functional performance remain identical across all suffix variants listed.

Q: Are there any compliance or certification differences between substitute parts?

A: No. All substitute parts carry identical ROHS3 compliance, REACH Unaffected status, MSL 2 rating, and EAR99 export classification, ensuring regulatory equivalence for global applications.

Q: What is the lead time advantage of using substitute parts?

A: MP163CGS-5-Z (6150 units) and MP163AGS-33-Z (8810 units) offer significantly higher inventory levels compared to MP163BGS-33-Z (629 units), potentially reducing procurement lead times for high-volume production requirements.
