Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP4030AGS are classified based on the following substitution criteria:

Parametric Equivalents maintain identical or compatible electrical and mechanical specifications:

• AC DC offline switcher topology
• Flyback or compatible switching topology
• Triac dimming capability
• Single output configuration
• Surface mount packaging in 8-SOIC or equivalent footprint
• Operating temperature range of -40°C to 125°C
• Supply voltage compatibility within 11V to 27V range
• ROHS3 compliance and equivalent moisture sensitivity

Manufacturer Recommended Alternatives provide functional equivalence with allowable variations in:

• Package form factor (16-MSOP-EP vs. 8-SOIC)
• Frequency specification (25kHz ~ 300kHz vs. unspecified)
• Moisture sensitivity level (MSL 1 vs. MSL 2)
• Supply voltage specification (unspecified vs. 11V-27V)

Conditional Substitutes require design review due to parameter deviations:

• Topology variations (Buck/Boost vs. Flyback)
• Operating temperature range reduction (-40°C to 85°C vs. -40°C to 125°C)
• Product status changes (Obsolete or Last Time Buy vs. Active)
• Dimming capability differences

Parameter Comparison

Engineering Selection Recommendations

MP4030GS is the primary parametric equivalent to MP4030AGS. Both devices are manufactured by Monolithic Power Systems Inc. with identical electrical specifications, operating temperature range, and package configuration. The only distinction is packaging format (Tube vs. standard). This part is recommended for direct replacement with no design modifications required. Product status is Active with equivalent inventory availability.

LT3799EMSE#PBF and LT3799IMSE-1#PBF are manufacturer-recommended alternatives from Analog Devices Inc. These devices maintain Flyback topology, Triac dimming, and -40°C to 125°C operating temperature compatibility. The primary design consideration is the package change from 8-SOIC to 16-MSOP-EP, requiring PCB layout modification. Both parts carry superior moisture sensitivity rating (MSL 1 vs. MSL 2) and maintain Active product status. Frequency specification (25kHz ~ 300kHz) is provided, whereas the MP4030AGS does not specify frequency. Supply voltage parameters are not specified for these parts; verification against application requirements is necessary.

RT8415GSP is classified as a conditional substitute due to multiple parameter deviations. The device is Obsolete with extended MSL rating (MSL 3), indicating higher moisture sensitivity. Topology differs (Buck/Boost vs. Flyback), and operating temperature maximum is reduced to 85°C. Supply voltage range is broader (4.5V - 36V) but includes the MP4030AGS operating window. Triac dimming is not specified. This part should be considered only when supply chain constraints require it, with full design validation.

TPS92002DR carries Last Time Buy status, indicating discontinued production with limited remaining inventory (1085 units). Operating temperature is reduced to -40°C to 85°C. Topology combines Flyback and Buck configurations. Supply voltage specification is incomplete (maximum 21V specified, minimum not provided). This part is suitable for existing designs requiring continuity but not recommended for new designs. Triac dimming capability is confirmed.

All substitute parts maintain ROHS3 compliance and EAR99 export classification consistent with the primary device.

Frequently Asked Questions (FAQ)

Q: Can MP4030GS be used as a direct replacement for MP4030AGS?

A: Yes. MP4030GS is a parametric equivalent with identical electrical specifications, operating temperature range (-40°C to 125°C), supply voltage (11V - 27V), package footprint (8-SOIC), and Triac dimming capability. The only difference is packaging format (Tube). No design modifications are required.

Q: What is the primary design consideration when substituting LT3799EMSE#PBF or LT3799IMSE-1#PBF?

A: The package changes from 8-SOIC to 16-MSOP-EP, requiring PCB layout redesign. Pin count increases from 8 to 16, and physical dimensions differ. Electrical functionality remains compatible for Flyback topology with Triac dimming and -40°C to 125°C operation. Supply voltage specifications are not provided for these parts; application voltage requirements must be verified independently.

Q: Why is RT8415GSP marked as Obsolete?

A: RT8415GSP has reached end-of-life status and is no longer in active production. The device carries MSL 3 rating (168 hours), indicating higher moisture sensitivity than the MP4030AGS (MSL 2, 1 year). Operating temperature is limited to -40°C to 85°C. Topology differs (Buck/Boost vs. Flyback). This part should be used only when supply constraints require it, with comprehensive design validation.

Q: Is TPS92002DR suitable for new designs?

A: No. TPS92002DR carries Last Time Buy status with limited inventory (1085 units). Production has been discontinued. Operating temperature is reduced to -40°C to 85°C compared to MP4030AGS (-40°C to 125°C). This part is appropriate only for maintaining existing designs or fulfilling final orders. New designs should use Active status alternatives.

Q: What parameters determine substitutability for LED driver ICs in this category?

A: Critical substitution parameters include: AC DC offline switcher topology, Flyback or compatible switching topology, single output configuration, Triac dimming capability, operating temperature range (minimum -40°C to 125°C), supply voltage compatibility (11V to 27V window), surface mount packaging, and ROHS3 compliance. Package footprint compatibility (8-SOIC preferred) and moisture sensitivity rating should be evaluated for specific application environments.

Q: Can I use RT8415GSP if my application operates only at 85°C or below?

A: Potentially, but additional design review is required. RT8415GSP topology (Buck/Boost) differs from MP4030AGS (Flyback). Triac dimming is not specified for RT8415GSP. Supply voltage range (4.5V - 36V) encompasses the MP4030AGS window (11V - 27V). Obsolete status and MSL 3 rating present supply chain and reliability risks. This substitution requires full electrical and thermal validation before implementation.

Q: What is the difference between MSL 1, MSL 2, and MSL 3 ratings?

A: MSL (Moisture Sensitivity Level) indicates how sensitive a component is to moisture absorption during storage and handling. MSL 1 (Unlimited shelf life) provides maximum protection. MSL 2 (1 Year) requires controlled storage conditions. MSL 3 (168 Hours) demands the most stringent moisture control and shortest handling windows. MP4030AGS (MSL 2) requires standard moisture management. LT3799 variants (MSL 1) offer superior moisture tolerance. RT8415GSP (MSL 3) requires specialized handling procedures.
