Substitute Part Grouping Explanation

Substitute parts for the MP20056GJ-P are identified based on strict electrical and mechanical parameter matching within the allowed tolerance ranges for this product category. The substitution logic is based on the following critical parameters:

Electrical Compatibility Criteria:

Output Configuration: Positive (fixed requirement)
Output Type: Adjustable (fixed requirement)
Voltage - Input (Max): 5.5V (fixed requirement)
Voltage - Output Range: 0.8V to 5V (fixed requirement)
Current - Output: 250mA (fixed requirement)
Operating Temperature: -40°C ~ 125°C (fixed requirement)

Mechanical Compatibility Criteria:

Package / Case: SOT-23-5 Thin, TSOT-23-5 (fixed requirement)
Mounting Type: Surface Mount (fixed requirement)

Compliance Criteria:

RoHS Status: ROHS3 Compliant (fixed requirement)

Engineering Selection Recommendations

All three parts—MP20056GJ-P, MPQ20056GJ-P, and MPQ20056GJ-Z—are Active products from Monolithic Power Systems Inc. and carry ROHS3 compliance certification. Selection between these parts is based on availability and supply chain requirements rather than functional differences.

MP20056GJ-P serves as the primary reference part. MPQ20056GJ-P and MPQ20056GJ-Z are direct parametric equivalents suitable for substitution in applications where the primary part is unavailable. The voltage dropout specification difference (0.15V versus 0.2V @ 250mA) does not affect substitution eligibility for standard linear regulator applications within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can MPQ20056GJ-P and MPQ20056GJ-Z be used interchangeably with MP20056GJ-P?

A: Yes. Both substitute parts meet all electrical and mechanical requirements. They share identical output configuration, voltage ranges, current ratings, operating temperature range, package type, and protection features. The voltage dropout specification variance is within acceptable tolerance for this regulator class.

Q: Are there any package or pinout differences between these parts?

A: No. All three parts use the SOT-23-5 Thin (TSOT-23-5) package with identical mounting type (Surface Mount). Pinout and mechanical dimensions are equivalent.

Q: Do all parts carry the same compliance certifications?

A: Yes. MP20056GJ-P, MPQ20056GJ-P, and MPQ20056GJ-Z are all ROHS3 compliant and REACH unaffected. All carry Active product status.

Q: What is the significance of the voltage dropout difference?

A: The voltage dropout specification (0.15V for MP20056GJ-P versus 0.2V for the MPQ variants) indicates the minimum input-to-output voltage differential required for proper regulation at 250mA output current. Both values are within standard operating margins for adjustable linear regulators and do not restrict substitution in typical applications.

Q: Are these parts suitable for the same temperature range applications?

A: Yes. All three parts operate across the identical temperature range of -40°C to 125°C, ensuring compatibility in equivalent thermal environments.
