MP3398AGS-Z Equivalent & Substitute Parts
Part Overview
The MP3398AGS-Z is an active LED Driver IC manufactured by Monolithic Power Systems Inc., classified as a Power Management (PMIC) component. This device functions as a 4-output DC-DC controller with step-up (boost) topology, delivering 350mA per channel output current. The part is designed for backlight applications requiring analog and PWM dimming control across a 5V to 28V supply range. The MP3398AGS-Z maintains active product status with full ROHS3 compliance and is currently in stock with 55,400 units available. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter constraints.

Substitute Part Grouping Explanation
Substitute parts for the MP3398AGS-Z are identified based on strict electrical and mechanical parameter equivalence. The critical parameters determining substitution eligibility are:
- DC-DC controller topology (Step-Up/Boost)
- Number of outputs (4 channels)
- Output current per channel (350mA)
- Operating frequency (540kHz)
- Dimming capability (Analog and PWM)
- Supply voltage range compatibility (minimum 5V, maximum 28V)
- Package type (16-SOIC surface mount)
- Operating temperature range (-40°C to 125°C)
- Product status (Active)
- Compliance certifications (ROHS3, REACH Unaffected)
The MP3398LGS-Z qualifies as a parametric equivalent substitute. While the minimum supply voltage differs (4.5V vs. 5V), all other electrical specifications, package configuration, and compliance requirements remain identical. The packaging format difference (Tape & Reel vs. standard packaging) does not affect functional equivalence.

Engineering Selection Recommendations
Both the MP3398AGS-Z and MP3398LGS-Z maintain active product status with identical ROHS3 compliance and REACH unaffected certifications. Selection between these parts should be based on supply voltage requirements specific to the application. The MP3398AGS-Z operates with a minimum supply voltage of 5V, while the MP3398LGS-Z extends the lower operating limit to 4.5V, providing broader compatibility with lower-voltage supply rails. Both parts satisfy identical functional requirements for 4-channel LED driver applications with 350mA per-channel output capacity and dual-mode dimming control. Packaging format (standard vs. Tape & Reel) reflects inventory and procurement considerations rather than functional differences.
Frequently Asked Questions (FAQ)
Q: Can the MP3398LGS-Z directly replace the MP3398AGS-Z in existing designs?
A: Yes, the MP3398LGS-Z is a parametric equivalent substitute. All critical electrical specifications, package dimensions, and compliance certifications are identical. The lower minimum supply voltage (4.5V vs. 5V) provides additional operational flexibility without compromising compatibility.
Q: What is the significance of the packaging format difference between these parts?
A: The MP3398AGS-Z uses standard packaging while the MP3398LGS-Z is supplied in Tape & Reel (TR) format. This difference affects procurement, storage, and automated assembly processes but does not impact electrical performance or physical compatibility on the PCB.
Q: Are both parts suitable for backlight applications requiring PWM dimming?
A: Yes. Both the MP3398AGS-Z and MP3398LGS-Z support analog and PWM dimming modes, making them functionally equivalent for backlight control applications across the specified operating temperature range.
Q: What are the key parameters that must remain constant for substitution?
A: Substitution requires equivalence in DC-DC controller topology, 4-channel output configuration, 350mA per-channel current rating, 540kHz operating frequency, dual-mode dimming capability, 16-SOIC package format, and -40°C to 125°C operating temperature range.
Q: Do both parts meet the same compliance and certification requirements?
A: Yes. Both the MP3398AGS-Z and MP3398LGS-Z are ROHS3 compliant, REACH unaffected, and maintain MSL 2 (1 Year) moisture sensitivity ratings.
