MP163AGS-33-Z Equivalent & Substitute Parts

Part Overview

The MP163AGS-33-Z is an offline switch IC manufactured by Monolithic Power Systems Inc., classified as a Power Management (PMIC) component. This device functions as a converter supporting Boost, Buck, Buck-Boost, and Flyback topologies with a switching frequency of 28kHz and integrated fault protection including current limiting, overload, and short circuit protection. The part is Active status and widely used in offline power conversion applications requiring non-isolated topologies with 700V breakdown voltage capability. Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or inventory limitations while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP163AGS-33-Z are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain identical:

• Voltage - Breakdown: 700V
• Voltage - Supply (Vcc/Vdd): 5.4V ~ 6V
• Voltage - Start Up: 5.3V
• Frequency - Switching: 28kHz
• Power (Watts): 4W
• Topology: Boost, Buck, Buck-Boost, Flyback
• Output Isolation: Non-Isolated
• Internal Switch(s): Yes
• Fault Protection: Current Limiting, Over Load, Short Circuit
• Control Features: EN, Soft Start
• Operating Temperature: -40°C ~ 125°C (TJ)
• Package / Case: 8-SOIC (0.154", 3.90mm Width), 7 Leads
• Supplier Device Package: 8-SOIC-7B
• Mounting Type: Surface Mount
• Product Status: Active
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 2 (1 Year)
• REACH Status: REACH Unaffected

All substitute parts listed below maintain complete parametric equivalence across these criteria and are manufactured by Monolithic Power Systems Inc. within the MP163 base product family.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—MP163BGS-33-Z, MP163CGS-33-Z, and MP163CGS-5-Z—are Active status components manufactured by Monolithic Power Systems Inc. and maintain full parametric equivalence with the MP163AGS-33-Z. Each substitute part is ROHS3 Compliant and REACH Unaffected, meeting the same regulatory and environmental compliance standards as the primary part. Selection among these equivalents may be based on inventory availability and lead time considerations. All parts are suitable for direct substitution in applications requiring offline switch functionality with Boost, Buck, Buck-Boost, or Flyback topology support.

Frequently Asked Questions (FAQ)

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

A: Yes. All substitute parts maintain identical electrical specifications including 700V breakdown voltage, 5.4V ~ 6V supply voltage range, 28kHz switching frequency, 4W power rating, and identical fault protection and control features. All parts use the same 8-SOIC-7B package with 7 leads and identical mounting specifications.

Q: Are there any differences in operating temperature range between the main part and substitutes?

A: No. All parts operate across the identical temperature range of -40°C ~ 125°C (TJ).

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

A: Yes. All parts are ROHS3 Compliant, REACH Unaffected, and carry MSL 2 (1 Year) moisture sensitivity rating.

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

A: The suffixes represent different manufacturing lots or date codes within the MP163 base product family. All variants maintain identical electrical and mechanical specifications and are fully interchangeable.

Q: Can these parts be used in both isolated and non-isolated topologies?

A: These parts are specified for non-isolated topologies only. They support Boost, Buck, Buck-Boost, and Flyback configurations without output isolation.

Q: Are there inventory differences between the substitute parts?

A: Inventory levels vary by part number. MP163AGS-33-Z has 8810 pcs available, MP163BGS-33-Z has 629 pcs, MP163CGS-33-Z has 1126 pcs, and MP163CGS-5-Z has 6150 pcs. Selection may depend on required delivery timeline and quantity needs.
