Key Parameters

Substitute Part Grouping Explanation

Substitution for the MP4034GS-Z is determined by the following critical parameters:

• Topology: Flyback AC DC offline switcher architecture
• Internal Switch Requirement: Presence of integrated power switch
• Supply Voltage Range: Compatibility with 6.6V to 28V input
• Package Compatibility: Surface mount form factor suitable for PCB integration
• Single Output Configuration: Single-channel LED driver output
• Operating Temperature Range: Support for -40°C to 125°C junction temperature
• RoHS Compliance: ROHS3 compliance for regulatory alignment

Substitute parts are grouped based on topology alignment (flyback), internal switch presence, and voltage operating range overlap. Parts with different topologies (buck converters) or significantly different voltage ranges are included where they serve the same functional role in LED driver applications, provided they maintain single-output configuration and surface mount packaging.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility)

TPS92010D and TPS92314ADR/NOPB are the most direct substitutes for the MP4034GS-Z. Both are active products from Texas Instruments with flyback topology, single-output configuration, and surface mount 8-SOIC packaging. TPS92010D maintains the same package footprint and supports the lower voltage range (up to 21V), while TPS92314ADR/NOPB extends the upper voltage limit to 35V. Both devices carry ROHS3 compliance and active product status, ensuring long-term availability and design support.

Secondary Substitutes (Topology-Compatible)

TPS92315DBVR offers flyback topology in a compact SOT-23-6 surface mount package with a 9V to 35V supply range. This device is suitable for space-constrained applications and maintains ROHS3 compliance with active product status. LM3447MT/NOPB provides flyback topology with triac dimming capability and operates across 7.5V to 17.5V, offering extended temperature range support (-40°C to 125°C).

Alternative Topology (Buck Converter)

AL9901FDF-13 from Diodes Incorporated represents a different topology (step-down buck) but serves LED driver applications with a higher supply voltage range (15V to 500V). This part is suitable only where the application topology can accommodate buck converter operation and where the higher voltage range is beneficial.

Mounting Consideration

LNK406LG from Power Integrations operates through-hole mounting (eSIP-7F package), which differs from the surface mount requirement of MP4034GS-Z. This part is applicable only in designs where through-hole mounting is acceptable and where the extended voltage range (36V to 725V) aligns with application requirements.

All recommended substitutes maintain ROHS3 compliance and active product status, ensuring regulatory alignment and ongoing manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can TPS92010D directly replace MP4034GS-Z without PCB modifications?

A: TPS92010D shares the same 8-SOIC package footprint and surface mount configuration as MP4034GS-Z, enabling direct pin-compatible replacement. However, the maximum supply voltage of TPS92010D is 21V compared to MP4034GS-Z's 28V maximum. Verify that your application supply voltage does not exceed 21V before substitution.

Q: What is the key difference between TPS92314ADR/NOPB and TPS92010D?

A: Both devices use 8-SOIC surface mount packaging and flyback topology. TPS92314ADR/NOPB extends the maximum supply voltage to 35V and operates at 60kHz to 150kHz frequency range, while TPS92010D supports up to 21V with 1A output current. Select TPS92314ADR/NOPB for higher voltage applications and TPS92010D for lower voltage designs requiring higher output current.

Q: Is AL9901FDF-13 a suitable replacement for MP4034GS-Z?

A: AL9901FDF-13 uses step-down (buck) topology rather than flyback, making it suitable only for applications where buck converter operation is acceptable. It requires a minimum 15V supply voltage and provides 400mA switch current with analog and PWM dimming. This part is not a direct functional replacement but serves similar LED driver applications with different topology requirements.

Q: Why does LNK406LG use through-hole mounting while MP4034GS-Z is surface mount?

A: LNK406LG employs eSIP-7F through-hole package configuration, requiring different PCB layout and assembly processes compared to MP4034GS-Z's 8-SOIC surface mount package. This part is applicable only in designs where through-hole mounting infrastructure is available and where the extended voltage range (36V to 725V) is required.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts maintain ROHS3 compliance, ensuring regulatory alignment with current environmental standards. MP4034GS-Z also carries ROHS3 compliance, and all active substitutes preserve this certification status.

Q: What is the significance of "Not For New Designs" status on MP4034GS-Z?

A: This designation indicates that MP4034GS-Z has reached end-of-life status and is no longer recommended for new product development. All listed substitute parts carry "Active" product status, ensuring ongoing manufacturing support, technical documentation availability, and long-term supply chain reliability for new designs and legacy system maintenance.
