Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MPQ7221GRE-AEC1-Z are identified based on strict parameter matching across the following critical specifications:

• Number of Outputs: 16 channels (required match)
• Current per Channel: 80mA (required match)
• Supply Voltage Range: 4.5V to 16V (required match)
• Package Type: 24-QFN (4x4) with wettable flank (required match)
• Dimming Control: Analog, I2C, PWM (required match)
• Operating Temperature: -40°C to 125°C (required match)
• Automotive Grade: AEC-Q100 qualification (required match)
• RoHS Compliance: ROHS3 Compliant (required match)
• Manufacturer: Monolithic Power Systems Inc. (same manufacturer)

All substitute parts listed meet these criteria. Packaging format (Tape & Reel) is consistent across all variants. The MPQ3326BGRE series variants include specified frequency options (220Hz, 250Hz, 280Hz, 330Hz) not listed for the MPQ7221GRE series, but this does not affect substitution eligibility as frequency specifications are supplementary parameters.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are direct parametric equivalents to the MPQ7221GRE-AEC1-Z. Selection among these parts should be based on the following factors:

Packaging Suffix Consideration: The suffix designations (-Z and -P) indicate different packaging formats within the Tape & Reel category. Both formats are surface mount compatible with identical electrical and thermal characteristics. Selection between -Z and -P variants depends on specific assembly line requirements and tape configuration compatibility.

Inventory Availability: The MPQ3326BGRE-AEC1-Z variant offers the highest inventory level at 6031 units, followed by MPQ7221GRE-AEC1-P at 1510 units. Inventory considerations may influence part selection for high-volume production requirements.

Compliance and Qualification: All substitute parts maintain identical automotive-grade AEC-Q100 qualification, ROHS3 compliance, and MSL ratings. No compliance trade-offs exist between any of the listed alternatives.

Product Status: All parts are in active production status, ensuring long-term availability and continued manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can MPQ3326BGRE-AEC1-Z be used as a direct replacement for MPQ7221GRE-AEC1-Z?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, package type, and automotive qualification. The primary difference is the part number designation; both are 16-channel, 80mA per channel LED drivers in 24-QFN (4x4) packages with matching supply voltage ranges and dimming control options.

Q: What is the difference between the -Z and -P packaging suffixes?

A: The -Z and -P designations indicate different tape and reel configurations for surface mount assembly. Both are Tape & Reel packaging formats with identical electrical performance and thermal characteristics. Selection depends on compatibility with your specific pick-and-place equipment and tape specifications.

Q: Are all substitute parts automotive-grade qualified?

A: Yes. All listed substitute parts carry AEC-Q100 automotive qualification and are rated for -40°C to 125°C operating temperature range, meeting automotive reliability standards.

Q: Can I mix different part numbers in the same assembly?

A: Yes. All substitute parts are parametrically equivalent and can be used interchangeably from an electrical and functional standpoint. However, assembly line procedures and component traceability documentation should reflect the specific part number used.

Q: What is the MSL rating, and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture bake-out requirements. All listed parts have MSL 1 rating, meaning they can be stored and handled without special moisture control procedures.

Q: Are there any frequency differences between MPQ7221GRE and MPQ3326BGRE variants?

A: The MPQ3326BGRE series specifies operating frequencies of 220Hz, 250Hz, 280Hz, and 330Hz. The MPQ7221GRE series does not list specific frequency values in the provided specifications. Both series support identical dimming control methods (Analog, I2C, PWM) and are functionally equivalent for LED driver applications.
