MP4088GJ-P Equivalent & Substitute Parts

Part Overview

The MP4088GJ-P is an AC DC offline switcher LED driver IC manufactured by Monolithic Power Systems Inc. in active product status. This single-output power management IC integrates an internal switch and supports triac dimming for lighting applications. The device operates across a 4.5V to 5V supply range with a 22kHz switching frequency and is packaged in a compact TSOT-23-5 surface mount configuration.

Equivalent and substitute parts are identified when design requirements necessitate alternative packaging formats, different supply voltage ranges, or when primary component availability is constrained. Substitution eligibility is determined by matching core functional parameters: AC DC offline switcher topology, single output configuration, triac dimming capability, lighting application suitability, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All three components—MP4088GJ-P, LM3447MTE/NOPB, and TPS92075DR/NOPB—maintain active product status and full ROHS3 compliance with MSL Level 1 ratings, ensuring long-term availability and environmental regulatory adherence.

MP4088GJ-P is optimal for applications requiring the lowest supply voltage range (4.5V to 5V) with integrated internal switching and compact TSOT-23-5 packaging. This configuration minimizes board space and external component count.

LM3447MTE/NOPB accommodates higher supply voltage ranges (7.5V to 17.5V) with a flyback topology and 14-TSSOP packaging. This substitute is suitable for designs where higher input voltage tolerance and increased pin count for additional control features are beneficial.

TPS92075DR/NOPB supports the highest supply voltage range (11V to 18V) with step-down/step-up topology and 8-SOIC packaging. This option provides flexibility for designs operating at elevated input voltages with a moderate pin count.

Selection between substitutes depends on circuit supply voltage requirements, available PCB real estate for package footprints, and design topology preferences. All three parts maintain functional equivalence for triac-dimmed LED driver applications.

Frequently Asked Questions (FAQ)

Q: Can LM3447MTE/NOPB replace MP4088GJ-P in a 5V supply circuit?

A: LM3447MTE/NOPB has a minimum supply voltage of 7.5V, which exceeds the 5V maximum of MP4088GJ-P. Direct substitution in a 5V circuit is not supported by the specified electrical parameters.

Q: What is the primary difference between the three parts?

A: The three parts differ in supply voltage operating ranges, internal topologies (buck/boost versus flyback versus step-down/step-up), and package configurations. All maintain identical functional requirements for AC DC offline switching, single-output triac dimming, and lighting applications.

Q: Are package differences significant for substitution?

A: Yes. MP4088GJ-P uses TSOT-23-5 (5-pin), LM3447MTE/NOPB uses 14-TSSOP (14-pin), and TPS92075DR/NOPB uses 8-SOIC (8-pin). PCB layout, footprint design, and routing must accommodate the selected package. Pin assignments and functional pinout must be verified against individual datasheets.

Q: Do all three parts support triac dimming?

A: Yes. All three components explicitly support triac dimming and are rated for lighting applications with identical operating temperature ranges (-40°C to 125°C junction temperature).

Q: Are there compliance or certification differences?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 ratings. Compliance certifications are equivalent across all three options.

Q: Which part has the highest inventory availability?

A: TPS92075DR/NOPB has 2293 pieces in stock, followed by LM3447MTE/NOPB with 1277 pieces, and MP4088GJ-P with 1068 pieces.
