MP4088GJ-Z Equivalent & Substitute Parts

Part Overview

The MP4088GJ-Z is an LED driver IC manufactured by Monolithic Power Systems Inc., designed for AC DC offline switching applications with triac dimming capability. This single-output power management IC operates in the 4.5V to 5V supply range and is packaged in TSOT-23-5 surface mount format. The device is currently in active production status with 1100 units in stock inventory.

Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameters for offline LED driver applications, particularly where triac dimming or compatible dimming methods are supported.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP4088GJ-Z are identified based on the following critical parameters that define functional equivalence in offline LED driver applications:

Primary Substitution Criteria:

• AC DC offline switcher topology with buck and/or boost capability
• Single output configuration
• Triac dimming support or compatible dimming method (PWM, Analog)
• Lighting application suitability
• Active product status
• ROHS3 compliance and equivalent regulatory certifications
• Surface mount packaging

The two identified substitutes—AL9910A-5SP-13 (Diodes Incorporated) and TPS92075D/NOPB (Texas Instruments)—meet these functional requirements despite differences in supply voltage ranges and package formats. Both devices support offline switching with dimming capability and maintain compliance with environmental and trade regulations equivalent to the main part.

Parameter Comparison

Engineering Selection Recommendations

AL9910A-5SP-13 (Diodes Incorporated): This substitute is suitable for applications where the supply voltage range of 20V to 500V accommodates the system design. The device supports both analog and PWM dimming methods, providing flexibility beyond triac dimming. The 8-SO-EP package offers thermal management through an exposed pad. All regulatory certifications (ROHS3, REACH Unaffected, EAR99) align with the main part. Operating temperature range extends to 105°C (TA), which is 20°C lower than the main part's junction temperature specification.

TPS92075D/NOPB (Texas Instruments): This substitute maintains triac dimming compatibility with the main part and operates across -40°C to 125°C (TJ), matching the thermal specification of MP4088GJ-Z. The supply voltage range of 11V to 18V is narrower than AL9910A-5SP-13 but broader than the main part. The 8-SOIC package is standard for this device class. Regulatory compliance (ROHS3, REACH Unaffected, EAR99) is equivalent to the main part. Packaging is tube format rather than tape and reel.

Both substitutes maintain active product status and full regulatory compliance. Selection between them depends on specific supply voltage requirements, dimming method compatibility, and thermal operating conditions of the target application.

Frequently Asked Questions (FAQ)

Q: Can AL9910A-5SP-13 replace MP4088GJ-Z in a triac dimming circuit? A: AL9910A-5SP-13 supports analog and PWM dimming methods. Triac dimming compatibility requires verification against the specific application circuit topology, as the dimming method differs from the main part's native triac support.

Q: What is the primary difference in package format between these parts? A: MP4088GJ-Z uses TSOT-23-5 (5-pin thin SOT-23), while both substitutes use 8-SOIC packages. This requires PCB layout redesign and different pin assignment mapping.

Q: Are all three parts RoHS compliant? A: Yes. MP4088GJ-Z, AL9910A-5SP-13, and TPS92075D/NOPB are all ROHS3 compliant with REACH Unaffected status.

Q: Which substitute is better for high-temperature applications? A: Both MP4088GJ-Z and TPS92075D/NOPB operate to 125°C (TJ). AL9910A-5SP-13 operates to 105°C (TA), making it less suitable for applications requiring sustained operation above 105°C.

Q: What supply voltage range does each part support? A: MP4088GJ-Z operates at 4.5V–5V. TPS92075D/NOPB operates at 11V–18V. AL9910A-5SP-13 operates at 20V–500V, supporting the widest range for offline AC applications.

Q: Do all parts support buck and boost topologies? A: Yes. All three devices support both step-down (buck) and step-up (boost) switching topologies for offline LED driver applications.
