MP4026GJ-P LED Driver IC Equivalent & Substitute Parts

Part Overview

The MP4026GJ-P is an AC DC offline switcher LED driver IC manufactured by Monolithic Power Systems, designed for lighting applications. It features a flyback topology with a single output and operates across a 9.8V to 27V supply voltage range in a TSOT-23-6 surface mount package. The device is currently in active production status with 1245 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative packaging or thermal specifications are required, or when design flexibility demands components with different topologies or supply voltage ranges while maintaining functional compatibility for LED driver applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP4026GJ-P are qualified based on the following criteria:

Primary Substitution Criteria:

• AC DC offline switcher topology for lighting applications
• Single output configuration
• Surface mount packaging
• ROHS3 compliance and EAR99 classification
• Operating temperature capability suitable for LED driver use

Secondary Compatibility Factors:

• Supply voltage range overlap or compatibility with 9.8V to 27V nominal range
• Package form factor (TSOT-23-6, 8-SOIC, or SOT-23-5)
• Internal switch configuration
• Dimming capability support

The three substitute parts identified represent different topology and packaging trade-offs while maintaining core AC DC offline switcher functionality for LED driver applications.

Parameter Comparison

Engineering Selection Recommendations

NCL30088DDR2G (onsemi): This part maintains flyback topology identical to the MP4026GJ-P with active product status. The supply voltage range (8.8V to 20V) overlaps the lower portion of the MP4026GJ-P range. The 8-SOIC package requires PCB layout modification compared to TSOT-23-6. MSL rating of 3 requires controlled moisture handling during storage and assembly. Suitable for designs where package size is not constrained and lower supply voltage operation is acceptable.

RT8402GJ6 (Richtek USA Inc.): This part shares the TSOT-23-6 package footprint with the MP4026GJ-P, enabling direct PCB layout compatibility. However, the product status is obsolete, limiting long-term availability. The topology differs (Step-Down Buck versus Flyback), and the operating temperature maximum is 85°C, lower than the MP4026GJ-P. The supply voltage range (10V to 30V) extends above the primary part. This substitute is not recommended for new designs due to obsolete status.

TPS92411PDBVT (Texas Instruments): This part offers the widest supply voltage range (7.5V to 94V) and highest operating temperature rating (150°C TJ), providing maximum design flexibility. The device includes an internal switch and supports multiple topologies (Flyback, Buck, Boost). MSL rating of 1 matches the MP4026GJ-P. The SOT-23-5 package differs from TSOT-23-6, requiring PCB layout changes. Active product status with 20050 units in stock ensures availability. Suitable for designs requiring extended voltage range or higher temperature operation.

Frequently Asked Questions (FAQ)

Q: Can NCL30088DDR2G directly replace MP4026GJ-P on the same PCB?

A: No. While both are AC DC offline switcher LED drivers with flyback topology, the NCL30088DDR2G uses an 8-SOIC package versus the TSOT-23-6 package of the MP4026GJ-P. PCB layout modification is required. Additionally, the maximum supply voltage of NCL30088DDR2G is 20V, which may limit operation if the design uses the full 27V range of the MP4026GJ-P.

Q: Why is RT8402GJ6 listed as a substitute if it is obsolete?

A: RT8402GJ6 is included in the substitute list based on the manufacturer's original recommendation data. However, obsolete status indicates this part is no longer in active production. For new designs or long-term production, RT8402GJ6 is not recommended. Existing inventory may be available through secondary distributors, but supply cannot be guaranteed.

Q: What are the key differences between TPS92411PDBVT and MP4026GJ-P?

A: TPS92411PDBVT offers a wider supply voltage range (7.5V to 94V versus 9.8V to 27V), higher maximum operating temperature (150°C TJ versus 125°C TJ), and includes an internal switch. The package is SOT-23-5 instead of TSOT-23-6, requiring PCB redesign. Both devices are ROHS3 compliant with MSL rating of 1. TPS92411PDBVT is suitable for designs requiring extended voltage or temperature specifications.

Q: Does package difference affect electrical performance?

A: Package differences do not directly affect electrical performance specifications. However, package selection impacts PCB layout, thermal dissipation characteristics, and manufacturing process compatibility. TSOT-23-6 and SOT-23-5 packages have different pin counts and thermal properties. 8-SOIC packages typically offer better thermal performance than smaller packages due to larger die attachment area.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (NCL30088DDR2G, RT8402GJ6, and TPS92411PDBVT) are ROHS3 compliant, matching the compliance status of the MP4026GJ-P. All parts are also EAR99 classified and REACH unaffected.

Q: What does MSL rating mean for component selection?

A: MSL (Moisture Sensitivity Level) rating indicates the maximum time a component can be exposed to moisture before assembly. MP4026GJ-P and TPS92411PDBVT have MSL 1 (unlimited exposure time). NCL30088DDR2G and RT8402GJ6 have MSL 3 (168 hours maximum). MSL 3 components require controlled storage in dry conditions and must be baked before reflow soldering if moisture absorption limits are exceeded.
