Key Parameters

Substitute Part Grouping Explanation

The S-8424AAAFT-TB-U qualifies as a substitute for the MP6922N-HGS based on the following alignment of critical parameters:

Functional Category: Both devices are Power Management (PMIC) controllers designed for power supply switching and control applications.

Mounting Technology: Both are surface mount devices, enabling compatibility with existing PCB assembly processes.

Supply Voltage Compatibility: The MP6922N-HGS operates at 8V ~ 24V supply voltage. The S-8424AAAFT-TB-U accepts 1.7V ~ 16V input voltage, with the overlap range of 8V ~ 16V providing functional compatibility for the specified application envelope.

Operating Temperature Range: The MP6922N-HGS supports -40°C ~ 125°C. The S-8424AAAFT-TB-U supports -40°C ~ 85°C, covering the lower temperature range and most industrial operating conditions.

Regulatory Compliance: Both devices are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.

Package Form Factor: While the MP6922N-HGS uses 8-SOIC (3.90mm width) and the S-8424AAAFT-TB-U uses 8-TSSOP (4.40mm width), both are 8-pin surface mount packages with similar pin pitch, allowing PCB layout adaptation.

Parameter Comparison

Engineering Selection Recommendations

The S-8424AAAFT-TB-U is an active product with current manufacturing availability (4975 pcs in stock), providing supply chain continuity for applications previously served by the discontinued MP6922N-HGS.

Both devices meet ROHS3 compliance and REACH regulatory requirements, ensuring equivalent environmental and safety standards for industrial and consumer applications.

The S-8424AAAFT-TB-U is supplied in Tape & Reel format, supporting high-volume production assembly processes. The package transition from 8-SOIC to 8-TSSOP requires PCB layout modification but does not impact electrical functionality within the specified operating parameters.

The operating temperature range of the S-8424AAAFT-TB-U (-40°C ~ 85°C) is suitable for standard industrial and commercial applications. Applications requiring operation above 85°C require evaluation of alternative substitutes.

Frequently Asked Questions (FAQ)

Q: Can the S-8424AAAFT-TB-U directly replace the MP6922N-HGS without PCB modification?

A: The S-8424AAAFT-TB-U requires PCB layout adaptation due to package differences (8-SOIC vs. 8-TSSOP). Pin pitch compatibility allows footprint redesign, but direct socket substitution is not possible.

Q: What is the voltage compatibility range between these two devices?

A: The MP6922N-HGS operates at 8V ~ 24V supply voltage. The S-8424AAAFT-TB-U accepts 1.7V ~ 16V input voltage. The overlapping functional range is 8V ~ 16V, which covers standard AC-DC adapter and telecom SMPS applications within this envelope.

Q: Are there temperature limitations when using the S-8424AAAFT-TB-U as a substitute?

A: The S-8424AAAFT-TB-U supports -40°C ~ 85°C operating temperature, compared to the MP6922N-HGS range of -40°C ~ 125°C. Applications requiring sustained operation above 85°C require alternative component selection.

Q: Do both devices meet the same regulatory compliance standards?

A: Yes. Both the MP6922N-HGS and S-8424AAAFT-TB-U are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements.

Q: What packaging considerations apply to the S-8424AAAFT-TB-U?

A: The S-8424AAAFT-TB-U is supplied in Tape & Reel (TR) format, optimized for automated assembly processes. The 8-TSSOP package (4.40mm width) is slightly wider than the original 8-SOIC (3.90mm width), requiring PCB footprint adjustment.
