MP8716EN-LF-Z Equivalent & Substitute Parts

Part Overview

The MP8716EN-LF-Z is a buck switching regulator IC manufactured by Monolithic Power Systems, designed for positive adjustable output applications. This device delivers 3A output current with an adjustable output voltage range from 0.8V to 18.9V, operating from a 4.5V to 21V input supply. The component is housed in an 8-SOIC package with exposed pad and features a 500kHz switching frequency with integrated synchronous rectification.

The MP8716EN-LF-Z carries a "Not For New Designs" product status, indicating it is obsolete or in end-of-life phase. This status necessitates identification of functionally equivalent alternatives for ongoing production requirements and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP8716EN-LF-Z is determined by the following critical parameters:

• Input voltage range: 4.5V to 21V minimum
• Output current capability: 3A minimum
• Output voltage adjustability: Minimum 0.8V reference or lower
• Switching frequency: 500kHz
• Package compatibility: 8-SOIC with exposed pad
• Synchronous rectification: Required
• RoHS3 compliance: Required

The RT7263EZSP meets these substitution criteria across all electrical and mechanical specifications, with the exception of maximum output voltage range (15V vs. 18.9V) and operating temperature lower bound (-40°C vs. -20°C). These differences represent enhanced performance characteristics in the substitute part.

Parameter Comparison

Engineering Selection Recommendations

The RT7263EZSP is a direct functional equivalent for the MP8716EN-LF-Z in applications where the maximum output voltage requirement does not exceed 15V. Both devices share identical input voltage ranges, output current ratings, switching frequency, package geometry, and RoHS3 compliance status.

The RT7263EZSP carries an "Active" product status, ensuring continued availability and manufacturing support. The substitute part provides an extended operating temperature range (-40°C to 85°C versus -20°C to 85°C), which represents an advantage for applications requiring lower temperature operation.

For applications requiring output voltages between 15V and 18.9V, the RT7263EZSP is not suitable as a direct substitute. Alternative components with higher maximum output voltage ratings must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the RT7263EZSP replace the MP8716EN-LF-Z in all applications?

A: The RT7263EZSP is suitable for applications where the required output voltage does not exceed 15V. The MP8716EN-LF-Z supports output voltages up to 18.9V. If your design requires output voltages above 15V, the RT7263EZSP is not a compatible substitute.

Q: Are the packages physically identical?

A: Both the MP8716EN-LF-Z and RT7263EZSP use the 8-SOIC package with 0.154" width and exposed pad. PCB footprints are compatible without modification.

Q: What is the difference in minimum output voltage between these parts?

A: The MP8716EN-LF-Z has a minimum output voltage of 0.8V, while the RT7263EZSP has a minimum of 0.808V. This 8mV difference is negligible for most adjustable regulator applications using standard feedback resistor networks.

Q: Does the RT7263EZSP offer any performance advantages?

A: The RT7263EZSP extends the operating temperature range to -40°C, compared to -20°C for the MP8716EN-LF-Z. Both devices operate at identical 500kHz switching frequency and deliver 3A output current with synchronous rectification.

Q: Are both parts RoHS3 compliant?

A: Yes, both the MP8716EN-LF-Z and RT7263EZSP are ROHS3 compliant and REACH unaffected.
