MP4056GS-Z Equivalent & Substitute Parts

Part Overview

The MP4056GS-Z is an AC DC offline switcher LED driver IC manufactured by Monolithic Power Systems Inc. This single-output power management IC integrates Triac dimming capability for commercial and industrial lighting applications. The device operates across a 11V to 27V supply range and supports multiple topologies including Flyback, Step-Down (Buck), and Step-Up (Boost) configurations. The MP4056GS-Z maintains active product status with 37,700 units in current inventory. Substitute parts are identified for applications requiring equivalent LED driver functionality with compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP4056GS-Z are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Package compatibility: 8-SOIC form factor
• Product category: Power Management (PMIC) / LED Driver IC
• Type: AC DC Offline Switcher
• Number of outputs: Single output
• Operating temperature range: -40°C to 125°C (TJ)
• Surface mount mounting type
• RoHS3 compliance

Secondary Compatibility Factors:

• Dimming capability (Triac dimming for full equivalence)
• Supported topologies (Step-Down/Buck and Step-Up/Boost)
• Supply voltage range overlap

The MP4056GS-Z specifies a maximum supply voltage of 27V. Substitute parts with lower maximum supply voltage ratings (18V) remain functionally compatible for applications operating within the 11V to 18V range. Parts lacking Triac dimming capability are classified as functional substitutes for non-dimming applications.

Parameter Comparison

Engineering Selection Recommendations

TPS92075D/NOPB (Primary Substitute)

The TPS92075D/NOPB from Texas Instruments is the primary substitute for the MP4056GS-Z in Triac dimming applications. Both devices share identical Triac dimming capability, single-output configuration, and 8-SOIC package format. Operating temperature ranges are equivalent at -40°C to 125°C (TJ). Both parts maintain active product status and ROHS3 compliance. The TPS92075D/NOPB operates within the 11V to 18V supply range, making it suitable for applications where the MP4056GS-Z's extended 27V maximum is not required. Moisture sensitivity level is superior (MSL 1 Unlimited vs. MSL 2 1 Year).

TPS92074DR (Secondary Substitute)

The TPS92074DR from Texas Instruments is a functional substitute for non-dimming LED driver applications. This device shares the same 8-SOIC package, 11V to 18V supply range, and -40°C to 125°C operating temperature with the MP4056GS-Z. Both support Step-Down (Buck) and Step-Up (Boost) topologies. The TPS92074DR lacks specified Triac dimming capability and is therefore suitable only for fixed-output lighting applications. ROHS3 compliance and active product status are maintained.

Frequently Asked Questions (FAQ)

Q: Can the TPS92075D/NOPB directly replace the MP4056GS-Z in all applications?

A: The TPS92075D/NOPB is a direct substitute for applications operating within the 11V to 18V supply range. The MP4056GS-Z supports supply voltages up to 27V; applications requiring operation above 18V require the original MP4056GS-Z or equivalent parts rated for higher supply voltages.

Q: What is the key difference between TPS92075D/NOPB and TPS92074DR?

A: The TPS92075D/NOPB includes Triac dimming capability, while the TPS92074DR does not specify dimming functionality. Select TPS92075D/NOPB for dimming-enabled lighting designs and TPS92074DR for fixed-output applications.

Q: Are all substitute parts in the same 8-SOIC package?

A: Yes. The MP4056GS-Z, TPS92075D/NOPB, and TPS92074DR all use the 8-SOIC (0.154", 3.90mm Width) package format, ensuring mechanical compatibility on PCB layouts.

Q: Do substitute parts meet the same compliance standards?

A: All listed parts maintain ROHS3 compliance and active product status. Operating temperature ranges are identical at -40°C to 125°C (TJ). Moisture sensitivity levels differ: MP4056GS-Z is MSL 2 (1 Year), while Texas Instruments parts are MSL 1 (Unlimited).

Q: What topologies does each part support?

A: The MP4056GS-Z supports Flyback, Step-Down (Buck), and Step-Up (Boost) topologies. Both TPS92075D/NOPB and TPS92074DR support Step-Down (Buck) and Step-Up (Boost) topologies. Applications requiring Flyback topology must use the MP4056GS-Z.

Q: Is the internal switch configuration a substitution factor?

A: The MP4056GS-Z includes an internal switch, while TPS92075D/NOPB and TPS92074DR do not. This difference reflects design architecture but does not prevent functional substitution in equivalent circuit topologies.
