Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP163CGS-5-Z are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. 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
• Package / Case: 8-SOIC (0.154", 3.90mm Width), 7 Leads
• Operating Temperature: -40°C ~ 125°C (TJ)
• Fault Protection: Current Limiting, Over Load, Short Circuit
• Control Features: EN, Soft Start
• Output Isolation: Non-Isolated
• Internal Switch(s): Yes
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

All substitute parts listed maintain identical specifications across these parameters, ensuring direct functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—MP163AGS-33-Z, MP163BGS-33-Z, and MP163CGS-33-Z—are parametrically equivalent to the MP163CGS-5-Z and maintain identical electrical and mechanical specifications. Selection among these parts may be based on inventory availability and supply chain considerations. All parts are Active in product status, ROHS3 Compliant, and manufactured by Monolithic Power Systems Inc. with identical compliance certifications (REACH Unaffected, EAR99 ECCN classification, MSL 2 rating). No technical differentiation exists between these parts based on the provided specifications.

Frequently Asked Questions (FAQ)

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

A: Yes. All substitute parts maintain identical electrical parameters including voltage ratings (700V breakdown, 5.4V ~ 6V supply), switching frequency (28kHz), power rating (4W), supported topologies (Boost, Buck, Buck-Boost, Flyback), and package specifications (8-SOIC, 7 Leads). Direct PCB-level substitution is supported without circuit modification.

Q: Are there any differences in package or mounting between the main part and substitutes?

A: No. All parts use identical 8-SOIC (0.154", 3.90mm Width) packaging with 7 leads and surface mount mounting type. PCB footprints and assembly processes remain unchanged.

Q: Do all parts share the same compliance certifications?

A: Yes. All parts are ROHS3 Compliant, REACH Unaffected, classified as EAR99, with MSL 2 (1 Year) moisture sensitivity rating. Compliance documentation is equivalent across all parts.

Q: What is the difference between MP163CGS-5-Z and MP163CGS-33-Z?

A: Based on provided specifications, both parts are parametrically identical. The suffix difference (-5-Z versus -33-Z) does not reflect any electrical or mechanical parameter variation in the provided data.

Q: Which substitute part should be selected based on availability?

A: Selection should be based on current inventory levels and supply chain requirements. MP163AGS-33-Z has the highest inventory (8810 Pcs), followed by MP163CGS-33-Z (1126 Pcs) and MP163BGS-33-Z (629 Pcs).
