MP6922LGS Equivalent & Substitute Parts

Part Overview

The MP6922LGS is an intelligent controller IC manufactured by Monolithic Power Systems Inc., designed for AC-DC adapter, LCD & PDP TV, and telecom SMPS applications. This 8-SOIC surface mount device operates as a power management PMIC with a supply voltage range of 8V to 24V and supply current of 4mA. The product is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives that maintain compatibility with existing designs while meeting the same operational and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MP6922LGS is determined by the following critical parameters:

• Functional Category: Power Management PMIC for AC-DC conversion applications
• Supply Voltage Compatibility: Operating voltage range must accommodate the 8V ~ 24V input specification
• Supply Current: Maximum supply current of 4mA or lower indicates low-power controller operation
• Operating Temperature Range: -40°C ~ 125°C industrial temperature specification
• Package Compatibility: Surface mount 8-pin configuration (8-SOIC or equivalent 8-pin packages)
• Regulatory Compliance: ROHS3 and REACH compliance maintained across substitutes
• Application Domain: AC-DC adapter, LCD/PDP TV, and telecom SMPS controller functionality

The UCC24610DRBR qualifies as a substitute based on matching functional category, operating temperature range, surface mount configuration, and regulatory compliance. Package differences (8-VDFN vs. 8-SOIC) require PCB layout verification but do not preclude functional substitution.

Parameter Comparison

Engineering Selection Recommendations

The UCC24610DRBR is available as an active product with significantly higher inventory levels (23,100 units) compared to the discontinued MP6922LGS (5,200 units). Both devices maintain identical operating temperature specifications (-40°C ~ 125°C) and full regulatory compliance (ROHS3 and REACH). The UCC24610DRBR demonstrates lower supply current consumption (2.15mA vs. 4mA), which may provide marginal power efficiency improvements in low-power controller applications.

Package transition from 8-SOIC to 8-VDFN with exposed pad requires PCB layout modification and thermal management evaluation. The exposed pad in the UCC24610DRBR may provide improved thermal performance for applications requiring enhanced heat dissipation. Both devices are classified as EAR99 and share identical HTSUS codes (8542.39.0001), confirming regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can the UCC24610DRBR directly replace the MP6922LGS without PCB modification?

A: Package geometry differs between 8-SOIC and 8-VDFN configurations. Direct socket substitution is not possible. PCB layout redesign is required to accommodate the different pin pitch and exposed pad thermal connection of the UCC24610DRBR.

Q: Are the operating temperature ranges identical?

A: Yes. Both the MP6922LGS and UCC24610DRBR operate across the -40°C ~ 125°C temperature range, ensuring thermal compatibility in industrial applications.

Q: What is the significance of the exposed pad on the UCC24610DRBR?

A: The exposed pad provides a thermal connection point for improved heat dissipation. This feature may enhance performance in thermally demanding applications but requires proper PCB design with thermal vias and copper area for effective implementation.

Q: Are both devices RoHS and REACH compliant?

A: Yes. Both the MP6922LGS and UCC24610DRBR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the supply current difference between these devices?

A: The UCC24610DRBR operates at 2.15mA supply current compared to the MP6922LGS at 4mA. This 46% reduction in quiescent current may provide efficiency benefits in standby or low-power operating modes.

Q: Are there inventory considerations for design decisions?

A: The UCC24610DRBR has substantially higher inventory availability (23,100 units) versus the discontinued MP6922LGS (5,200 units). For new designs or production ramp, the UCC24610DRBR offers superior supply chain security and lead time assurance.
