Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP163BGS-33 are identified within the MP163 product family based on strict parameter matching. All substitute parts maintain identical electrical specifications across the following critical parameters: 700V breakdown voltage, 5.4V–6V supply voltage range, 5.3V startup voltage, 28kHz switching frequency, 4W power rating, boost/buck/buck-boost/flyback topology support, non-isolated output configuration, internal switching capability, and comprehensive fault protection (current limiting, overload, short circuit). All substitutes operate across the same temperature range (-40°C to 125°C junction temperature), use the same 8-SOIC-7B package with 7 leads, and maintain identical control features (enable and soft start functionality). Compliance certifications including ROHS3, REACH unaffected status, and moisture sensitivity level remain consistent across all variants.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts—MP163AGS-33, MP163CGS-33, and MP163CGS-5—are functionally equivalent to the MP163BGS-33 based on complete parameter alignment. All variants maintain active product status from Monolithic Power Systems Inc. and carry identical compliance certifications: ROHS3 compliance, REACH unaffected status, and MSL 2 moisture sensitivity rating. Selection among these parts may be based on inventory availability: MP163AGS-33 (1072 pcs), MP163CGS-33 (705 pcs), MP163CGS-5 (816 pcs), or MP163BGS-33 (782 pcs). No electrical or mechanical differentiation exists between these parts; substitution is direct and interchangeable for all applications requiring 700V offline power conversion with the specified topology and control features.

Frequently Asked Questions (FAQ)

Q: Can MP163AGS-33, MP163CGS-33, and MP163CGS-5 be used interchangeably with MP163BGS-33?

A: Yes. All parts share identical electrical specifications, operating parameters, package configuration, and compliance certifications. Direct substitution is supported without circuit modification.

Q: What determines compatibility between these MP163 variants?

A: Compatibility is determined by matching breakdown voltage (700V), supply voltage range (5.4V–6V), startup voltage (5.3V), switching frequency (28kHz), power rating (4W), topology support (boost/buck/buck-boost/flyback), output isolation (non-isolated), fault protection features, control features (EN, soft start), operating temperature range (-40°C to 125°C), and package type (8-SOIC-7B with 7 leads).

Q: Are there any package or pinout differences between these parts?

A: No. All variants use the identical 8-SOIC package with 0.154" width (3.90mm) and 7 leads. Pinout and mechanical footprint are identical across all substitutes.

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

A: Yes. All parts are ROHS3 compliant, REACH unaffected, and carry MSL 2 moisture sensitivity rating with 1-year shelf life under controlled conditions.

Q: What is the basis for part number variations (BGS, AGS, CGS, CGS-5)?

A: Part number suffixes indicate internal design variants within the MP163 family. All variants maintain identical electrical and mechanical specifications for the parameters provided, ensuring functional equivalence.
