MP4026GJ-Z Equivalent & Substitute Parts

Part Overview

The MP4026GJ-Z is an LED driver IC manufactured by Monolithic Power Systems Inc., designed for AC DC offline switcher applications with flyback topology. This single-output device operates across a 9.8V to 27V supply range and is housed in a TSOT-23-6 surface mount package. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter range, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP4026GJ-Z are classified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Substitution Criteria:

• Type: AC DC Offline Switcher
• Topology: Flyback (primary requirement)
• Number of Outputs: 1
• Supply Voltage Range: Minimum 9.8V, Maximum 27V
• Mounting Type: Surface Mount
• Applications: Lighting
• Product Status: Active
• RoHS Compliance: ROHS3 Compliant

Parametric Equivalent Classification: Parts meeting all primary criteria with identical or compatible package footprints qualify as parametric equivalents. The MP4026GJ-P maintains identical electrical specifications and TSOT-23-6 packaging, differing only in tape & reel packaging format.

Manufacturer Recommended Classification: The TPS92411DDAR is designated as a manufacturer-recommended substitute despite topology expansion (Flyback, Step-Down, Step-Up) and package variation (8-SO PowerPad). This part extends the supply voltage range (7.5V to 100V) and includes an internal switch, providing enhanced capability within the lighting application domain.

Parameter Comparison

Engineering Selection Recommendations

MP4026GJ-P (Parametric Equivalent): This part is a direct parametric equivalent with identical electrical specifications and package footprint. Selection is appropriate when supply chain availability or procurement lead times favor this variant. The difference in packaging format (tape & reel versus standard) does not affect electrical performance or board-level compatibility. Both parts maintain ROHS3 compliance and unlimited MSL rating.

TPS92411DDAR (Manufacturer Recommended): This part is recommended when design requirements permit package footprint change and extended operating temperature range (-40°C to 150°C). The expanded supply voltage range (7.5V to 100V) and integrated internal switch provide design flexibility for applications requiring broader input voltage tolerance. The MSL 2 rating (1 Year) requires controlled storage conditions compared to the MSL 1 rating of the primary part. All three parts maintain ROHS3 compliance and are active in production.

Frequently Asked Questions (FAQ)

Q: Can MP4026GJ-P be used as a direct replacement for MP4026GJ-Z? A: Yes. Both parts share identical electrical specifications, supply voltage range (9.8V to 27V), TSOT-23-6 package footprint, and operating temperature rating (125°C). The only difference is packaging format (tape & reel). No circuit modifications are required.

Q: What are the key differences between MP4026GJ-Z and TPS92411DDAR? A: The TPS92411DDAR differs in three areas: (1) package footprint changes from TSOT-23-6 to 8-SO PowerPad, requiring PCB layout modification; (2) supply voltage range expands from 9.8-27V to 7.5-100V; (3) operating temperature extends to -40°C to 150°C; (4) includes an internal switch versus external requirement. These differences require design validation before substitution.

Q: Is the TPS92411DDAR suitable for designs currently using MP4026GJ-Z? A: Electrical compatibility exists within the 9.8V to 27V operating range. However, package footprint change necessitates PCB redesign. The internal switch integration and expanded temperature range may require circuit topology review. Design validation is required before production implementation.

Q: What is the significance of MSL rating differences? A: MP4026GJ-Z and MP4026GJ-P carry MSL 1 (unlimited shelf life), while TPS92411DDAR carries MSL 2 (1 year shelf life). MSL 2 components require controlled storage and handling procedures to prevent moisture absorption. This affects supply chain management and component storage protocols.

Q: Are all three parts ROHS3 compliant? A: Yes. MP4026GJ-Z, MP4026GJ-P, and TPS92411DDAR are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for lighting applications.

Q: What packaging considerations apply when selecting between these parts? A: MP4026GJ-Z uses standard packaging while MP4026GJ-P uses tape & reel format—both fit TSOT-23-6 footprints without modification. TPS92411DDAR requires 8-SO PowerPad footprint, necessitating PCB layout changes and component placement adjustments.
