Parameter Comparison

Engineering Selection Recommendations

Both the MP6651GSS-0000-Z and MP6651GSS-0000-P are active production parts from Monolithic Power Systems Inc. with identical electrical specifications, mechanical packaging, and compliance certifications. Selection between these parts may be based on inventory availability and lead time requirements.

The MP6651GSS-0000-Z currently maintains 3502 units in new original inventory. The MP6651GSS-0000-P maintains 1622 units in new original inventory. Both parts carry ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity ratings, indicating equivalent environmental handling and storage requirements.

For applications requiring the 2A brushless DC motor driver with PWM control in an 8-SOIC package operating across 3.3V to 18V supply and load voltages, either part number provides equivalent functional performance across the specified operating temperature range of -40°C to 125°C junction temperature.

Frequently Asked Questions (FAQ)

Q: Can MP6651GSS-0000-P be used as a direct replacement for MP6651GSS-0000-Z in existing designs?

A: Yes. Both parts are manufactured by Monolithic Power Systems Inc. and share identical electrical parameters, output current rating (2A), voltage ranges (3.3V ~ 18V), motor type support (BLDC and Bipolar), output configuration (Half Bridge), interface protocol (PWM), and package specifications (8-SOIC). No circuit modifications are required.

Q: Are there any differences in the 8-SOIC package between these two part numbers?

A: No. Both parts use the identical 8-SOIC package with 0.154" width (3.90mm). Pin configuration, lead spacing, and surface mount footprint are equivalent. PCB layouts designed for one part number accommodate the other without modification.

Q: What is the significance of the packaging designation suffix (-Z versus -P)?

A: The packaging designation indicates the tape and reel configuration used for automated assembly. Both MP6651GSS-0000-Z and MP6651GSS-0000-P are supplied in Tape & Reel (TR) format. The suffix difference reflects manufacturing batch or distribution channel designation but does not affect electrical or mechanical specifications.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both parts are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. Both are REACH Unaffected and classified under ECCN EAR99 and HTSUS 8542.39.0001. Environmental handling, storage, and regulatory requirements are identical.

Q: What applications are these parts suitable for?

A: Both parts are designed for fan motor driver applications utilizing brushless DC motor control. The 2A output current, PWM interface, and half-bridge configuration support single-phase BLDC motor driving across industrial and consumer applications operating within the 3.3V to 18V supply voltage range.

Q: Are there any temperature or operating condition differences between the two parts?

A: No. Both parts operate across the identical temperature range of -40°C to 125°C junction temperature (TJ). Thermal performance and operating condition specifications are equivalent.
