Substitute Part Grouping Explanation

The MP6513GJ-Z qualifies as a manufacturer-recommended substitute based on the following substitution criteria:

Functional Equivalence: Both parts are motor driver ICs manufactured by Monolithic Power Systems Inc. and share the same base product family (MP65xx series).

Voltage Supply Compatibility: The MP6513GJ-Z operates across a 2.5V to 21V supply range, which encompasses the 2.5V to 14V operating window of the MP6514GGU-Z. This extended upper voltage limit maintains full compatibility within the original part's specified range.

Motor Drive Capability: The MP6513GJ-Z provides half-bridge (2) output configuration with power MOSFET technology, supporting brushed DC motor applications consistent with H-bridge motor driver functionality.

Compliance Alignment: Both parts maintain ROHS3 compliance, identical MSL ratings (1 - Unlimited), and equivalent REACH and ECCN classifications, ensuring regulatory and supply chain consistency.

Key Differentiators: Package format differs (TSOT-23-6 versus 8-UTQFN), and output current specification is provided for the substitute (800mA). These differences require PCB layout and thermal management reassessment during integration.

Parameter Comparison

Engineering Selection Recommendations

The MP6513GJ-Z is the manufacturer-recommended substitute for the MP6514GGU-Z. Selection of this alternative is justified by the following engineering factors:

Product Lifecycle Status: The MP6514GGU-Z is designated "Not For New Designs," whereas the MP6513GJ-Z maintains "Active" product status. This distinction ensures continued manufacturer support, availability of technical documentation, and supply chain reliability for new development initiatives.

Regulatory Compliance: Both parts maintain equivalent ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements without additional qualification steps.

Supply Chain Continuity: Current inventory levels for the MP6513GJ-Z (35,400 units) significantly exceed those of the MP6514GGU-Z (988 units), providing improved long-term availability and reduced procurement risk.

Functional Scope: The MP6513GJ-Z's extended voltage range (2.5V to 21V) and specified output current (800mA) provide documented performance parameters suitable for motor driver applications within the original part's operational envelope.

Integration Considerations: PCB redesign is required due to package format change from 8-UTQFN (2x2) to TSOT-23-6. Thermal management and signal routing must be reassessed during layout migration.

Frequently Asked Questions (FAQ)

Q: Can the MP6513GJ-Z directly replace the MP6514GGU-Z without PCB modification?

A: No. The MP6513GJ-Z uses a TSOT-23-6 package, while the MP6514GGU-Z uses an 8-UTQFN (2x2) package. Pin assignments and footprints differ, requiring PCB layout redesign and component repositioning.

Q: What is the significance of the "Not For New Designs" status on the MP6514GGU-Z?

A: This designation indicates that Monolithic Power Systems Inc. has concluded active development and support for this part. New designs should not incorporate this part number. The MP6513GJ-Z, with "Active" status, is the recommended path forward.

Q: Are the voltage supply ranges compatible between these parts?

A: Yes. The MP6513GJ-Z operates from 2.5V to 21V, which fully encompasses the MP6514GGU-Z's 2.5V to 14V range. Applications operating within the original voltage window will function within the substitute's specified limits.

Q: What motor types are supported by the MP6513GJ-Z?

A: The MP6513GJ-Z supports brushed DC motors and bipolar stepper motors through its half-bridge (2) output configuration and power MOSFET technology.

Q: How do the output current specifications compare?

A: The MP6513GJ-Z specifies 800mA output current. The MP6514GGU-Z does not provide this parameter in available documentation. Thermal and current-handling characteristics must be verified during design integration to ensure compatibility with target motor loads.

Q: Are moisture sensitivity and RoHS compliance identical?

A: Yes. Both parts maintain MSL rating 1 (Unlimited) and ROHS3 compliance, eliminating additional qualification requirements for these compliance aspects.

Q: What is the operating temperature range for the MP6513GJ-Z?

A: The MP6513GJ-Z operates from -40°C to 125°C (junction temperature). Verify that this range meets your application's thermal requirements.
