MP6902DS-LF-Z Equivalent & Substitute Parts

Part Overview

The MP6902DS-LF-Z is an active secondary-side controller IC manufactured by Monolithic Power Systems Inc., designed for power supply applications requiring isolated feedback control. This component operates within a supply voltage range of 8V to 24V and is housed in an 8-SOIC package. The part maintains Active product status with full RoHS3 compliance and REACH unaffected certification.

Secondary-side controller ICs are critical components in isolated power supply topologies. Equivalent and substitute parts become necessary due to supply chain constraints, design optimization requirements, or application-specific performance needs while maintaining functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP6902DS-LF-Z is determined by the following critical parameters:

• Functional Classification: Secondary-side controller for isolated power supply topologies
• Package Compatibility: Surface mount packages with compatible pinout and thermal characteristics
• Supply Voltage Range: Operating range of 8V to 24V or compatible subset
• Current Consumption: Supply current at or below 3 mA nominal
• Temperature Rating: Operating range of -40°C to 125°C or wider
• Compliance Standards: RoHS3 compliance and REACH unaffected status
• Moisture Sensitivity: MSL rating of 2 or better

The UCC24610DRBR from Texas Instruments qualifies as a manufacturer-recommended substitute based on functional equivalence as a secondary-side controller IC, surface mount technology, compatible temperature rating, and equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the MP6902DS-LF-Z and UCC24610DRBR maintain Active product status with identical compliance certifications (RoHS3 and REACH unaffected) and equivalent moisture sensitivity ratings. Both components support the full industrial temperature range of -40°C to 125°C.

The primary distinction between these parts lies in supply voltage specifications and package geometry. The MP6902DS-LF-Z operates across a wider supply voltage range (8V to 24V), while the UCC24610DRBR is specified for a narrower range (4.5V to 5.5V). Package differences include the MP6902DS-LF-Z in 8-SOIC form factor versus the UCC24610DRBR in 8-VDFN with exposed pad. These differences require circuit-level evaluation to confirm functional compatibility within the target application.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the MP6902DS-LF-Z?

A: A valid substitute must function as a secondary-side controller IC, operate within compatible supply voltage and temperature ranges, maintain surface mount technology, and comply with RoHS3 and REACH standards. Package pinout compatibility and thermal characteristics must also align with the application design.

Q: Can the UCC24610DRBR directly replace the MP6902DS-LF-Z in all applications?

A: Direct replacement requires verification of supply voltage compatibility. The UCC24610DRBR operates at 4.5V to 5.5V, which is a subset of the MP6902DS-LF-Z range of 8V to 24V. Applications requiring the full 8V to 24V range cannot use the UCC24610DRBR without circuit modification. Additionally, package geometry differences (8-SOIC versus 8-VDFN) require PCB layout evaluation.

Q: Are there package considerations when substituting these parts?

A: Yes. The MP6902DS-LF-Z uses an 8-SOIC package (0.154" width, 3.90mm), while the UCC24610DRBR uses an 8-VDFN package (3x3mm with exposed pad). These packages have different footprints, pin spacing, and thermal characteristics. PCB redesign may be necessary for physical substitution.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the MP6902DS-LF-Z and UCC24610DRBR are RoHS3 compliant, REACH unaffected, and carry MSL rating of 2 (1 Year). Both support the industrial temperature range of -40°C to 125°C.

Q: What is the current consumption difference between these parts?

A: The MP6902DS-LF-Z draws 3 mA supply current, while the UCC24610DRBR draws 2.15 mA. The UCC24610DRBR exhibits lower supply current consumption, which may provide marginal power efficiency benefits in applications where this parameter is critical.
