Substitute Part Grouping Explanation

Substitution of the MP20056GG-18-Z is determined by electrical and mechanical parameter equivalence. The primary substitute, MPQ20056GG-18-AEC1-Z, maintains identical electrical specifications across all critical parameters: fixed 1.8V output, 250mA output current, 5.5V maximum input voltage, 250 µA quiescent current, and identical PSRR characteristics. Both parts use the same 8-TFDFN Exposed Pad package and operate across the identical temperature range of -40°C to 125°C.

The key differentiator between these part numbers is packaging format and automotive qualification. The MP20056GG-18-Z is supplied in Tape & Reel (TR) format, while the MPQ20056GG-18-AEC1-Z is supplied in Cut Tape (CT) & Digi-Reel® format and includes AEC-Q100 automotive qualification. Both parts are ROHS3 compliant and carry identical protection features and control functionality.

Parameter Comparison

Engineering Selection Recommendations

Selection between MP20056GG-18-Z and MPQ20056GG-18-AEC1-Z depends on application requirements and supply chain constraints. Both parts are active products with ROHS3 compliance and identical electrical performance.

The MP20056GG-18-Z is suitable for standard industrial and consumer applications requiring tape & reel packaging. The MPQ20056GG-18-AEC1-Z is specified for automotive applications requiring AEC-Q100 qualification and is available in cut tape and Digi-Reel® formats. The automotive-grade variant carries higher inventory availability at 26,300 units compared to 15,570 units for the standard version.

Frequently Asked Questions (FAQ)

Q: Are MP20056GG-18-Z and MPQ20056GG-18-AEC1-Z electrically interchangeable?

A: Yes. Both parts deliver identical electrical performance with 1.8V fixed output, 250mA output current, 5.5V maximum input voltage, and matching PSRR characteristics across the full operating temperature range of -40°C to 125°C.

Q: What is the difference between these part numbers?

A: The primary differences are packaging format and automotive qualification. MP20056GG-18-Z uses Tape & Reel (TR) packaging, while MPQ20056GG-18-AEC1-Z uses Cut Tape (CT) & Digi-Reel® packaging and includes AEC-Q100 automotive qualification.

Q: Can I use MPQ20056GG-18-AEC1-Z in place of MP20056GG-18-Z?

A: Yes, provided your application and supply chain accept the automotive-grade variant and cut tape packaging format. The electrical and mechanical specifications are identical.

Q: Can I use MP20056GG-18-Z in place of MPQ20056GG-18-AEC1-Z?

A: No. The MP20056GG-18-Z lacks AEC-Q100 automotive qualification and is supplied in tape & reel format rather than cut tape. Automotive applications require the qualified MPQ20056GG-18-AEC1-Z variant.

Q: Are both parts ROHS3 compliant?

A: Yes. Both MP20056GG-18-Z and MPQ20056GG-18-AEC1-Z are ROHS3 compliant.

Q: What protection features are included in both parts?

A: Both parts include over-current protection, over-temperature protection, and under-voltage lockout (UVLO) functionality.
