Substitute Part Grouping Explanation

Substitute parts for the MP6923GS are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Functional category: Power Management (PMIC)
• Application type: Power supply controller functionality
• Mounting type: Surface mount
• RoHS compliance: ROHS3 Compliant
• Regulatory status: REACH Unaffected, EAR99 classification

The LTC2945CMS#PBF from Analog Devices Inc. is classified as a manufacturer-recommended substitute. Both devices operate as power management controllers with surface mount packaging and maintain equivalent regulatory compliance. Substitution feasibility is determined by electrical parameter compatibility within the specified operating ranges and package form factor considerations.

Parameter Comparison

Engineering Selection Recommendations

Both the MP6923GS and LTC2945CMS#PBF maintain Active product status and ROHS3 compliance, confirming ongoing manufacturer support and regulatory alignment. The MP6923GS operates across a wider supply voltage range (8V ~ 24V) compared to the LTC2945CMS#PBF (2.7V ~ 5.9V), and maintains a higher operating temperature ceiling (-40°C to 125°C versus 0°C to 70°C). The LTC2945CMS#PBF exhibits superior moisture sensitivity characteristics (MSL 1 versus MSL 2) and lower supply current consumption (800 µA versus 27 mA). Package differences exist between the 14-SOIC and 12-TSSOP form factors, requiring PCB layout verification. Selection between these parts must account for specific application voltage requirements, thermal operating conditions, and board space constraints.

Frequently Asked Questions (FAQ)

Q: What are the primary differences between MP6923GS and LTC2945CMS#PBF?

A: The MP6923GS supports a higher supply voltage range (8V ~ 24V) and wider operating temperature range (-40°C to 125°C), while the LTC2945CMS#PBF operates at lower supply voltages (2.7V ~ 5.9V) and narrower temperature range (0°C to 70°C). Package form factors differ: MP6923GS uses 14-SOIC while LTC2945CMS#PBF uses 12-TSSOP.

Q: Can LTC2945CMS#PBF replace MP6923GS in all applications?

A: Substitution feasibility depends on application-specific voltage and temperature requirements. The LTC2945CMS#PBF is suitable only for applications operating within its specified 2.7V ~ 5.9V supply range and 0°C ~ 70°C temperature envelope. Applications requiring the MP6923GS voltage or temperature range cannot use the LTC2945CMS#PBF as a direct substitute.

Q: Are both parts RoHS compliant?

A: Yes, both MP6923GS and LTC2945CMS#PBF are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What packaging considerations apply to substitution?

A: The MP6923GS uses 14-SOIC (0.154", 3.90mm width) while LTC2945CMS#PBF uses 12-TSSOP (0.118", 3.00mm width). PCB layout modifications may be required to accommodate the different package footprints and pin configurations.

Q: Which part has better moisture handling characteristics?

A: The LTC2945CMS#PBF has superior moisture sensitivity (MSL 1, unlimited shelf life) compared to the MP6923GS (MSL 2, 1-year shelf life), providing extended storage and handling flexibility.
