MP6910AGS-Z Equivalent & Substitute Parts

Part Overview

The MP6910AGS-Z is a Fast Turn-Off Intelligent Rectifier power supply controller manufactured by Monolithic Power Systems Inc., designed for distributed and industrial power systems applications. This 8-SOIC surface mount device operates across an 8V to 24V supply voltage range with a supply current of 2.6 mA and supports operating temperatures from -40°C to 125°C. The part maintains Active product status and is ROHS3 compliant with MSL 2 rating (1 Year). Substitute parts become necessary when addressing supply chain constraints, obsolescence concerns, or specific application requirements that align with the electrical and mechanical parameters of this device category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP6910AGS-Z are evaluated based on the following critical parameters that determine functional compatibility:

• Power Management Category: All substitutes must operate within the Power Management (PMIC) classification
• Supply Voltage Range: Substitutes must accommodate the 8V to 24V supply voltage specification
• Surface Mount Packaging: All alternatives use surface mount technology
• Operating Temperature Range: Substitutes must support operation within -40°C to 125°C or equivalent industrial temperature ranges
• RoHS3 Compliance: All qualified substitutes maintain ROHS3 compliance status
• Package Compatibility: Physical package dimensions and pin configurations must align with board-level integration requirements

The two identified substitute parts meet these criteria through equivalent electrical specifications and compatible packaging configurations, though with variations in specific package types and supply current characteristics.

Parameter Comparison

Engineering Selection Recommendations

NCP349MNTBG (onsemi): This substitute operates within an extended supply voltage range of 1.2V to 28V, exceeding the MP6910AGS-Z specification. However, the maximum operating temperature is limited to 85°C, which falls below the main part's 125°C upper limit. The part carries Obsolete product status, which may present long-term supply chain considerations. The 6-VFDFN package differs from the 8-SOIC configuration, requiring PCB layout modifications. ROHS3 compliance and MSL 1 rating (Unlimited) provide favorable compliance characteristics.

S-8424AAAFT-TB-U (ABLIC Inc.): This substitute maintains Active product status and operates within a supply voltage range of 1.7V to 16V, which overlaps the lower portion of the MP6910AGS-Z specification but does not extend to the full 24V upper limit. Maximum operating temperature is 85°C. The 8-TSSOP package provides similar pin count to the main part but with different physical dimensions (0.173" versus 0.154" width). ROHS3 compliance and MSL 1 rating (Unlimited) align with regulatory requirements. Tape & Reel packaging is specified.

Both substitutes maintain ROHS3 compliance and surface mount technology. Selection should prioritize application-specific voltage and temperature requirements against the provided parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can NCP349MNTBG replace MP6910AGS-Z in all applications?

A: NCP349MNTBG operates at a maximum temperature of 85°C, which is below the MP6910AGS-Z specification of 125°C. Applications requiring the full temperature range cannot use this substitute. Additionally, the 6-VFDFN package requires PCB redesign compared to the 8-SOIC footprint. The Obsolete product status may affect future availability.

Q: What are the package compatibility considerations for S-8424AAAFT-TB-U?

A: S-8424AAAFT-TB-U uses an 8-TSSOP package with 0.173" width, compared to the MP6910AGS-Z 8-SOIC package with 0.154" width. While both are 8-pin surface mount packages, the physical dimensions differ, requiring PCB layout verification. Pin-to-pin compatibility must be confirmed against schematic requirements.

Q: Does the supply voltage range difference affect substitution viability?

A: Yes. S-8424AAAFT-TB-U operates from 1.7V to 16V, which does not cover the full 8V to 24V range of the MP6910AGS-Z. Applications requiring operation above 16V cannot use this substitute. NCP349MNTBG extends to 28V but has a lower maximum operating temperature.

Q: Are all substitutes ROHS3 compliant?

A: Yes. Both NCP349MNTBG and S-8424AAAFT-TB-U maintain ROHS3 compliance, matching the main part specification.

Q: What is the significance of MSL ratings in these parts?

A: The MP6910AGS-Z carries MSL 2 (1 Year), requiring controlled moisture exposure during storage and handling. Both substitutes carry MSL 1 (Unlimited), providing more relaxed moisture sensitivity requirements and potentially longer shelf life without special storage conditions.

Q: Which substitute has Active product status?

A: S-8424AAAFT-TB-U maintains Active status. NCP349MNTBG is listed as Obsolete, which may impact long-term procurement and support availability.
