MP4032-2GS LED Driver IC Equivalent & Substitute Parts

Part Overview

The MP4032-2GS is an AC DC offline switcher LED driver IC manufactured by Monolithic Power Systems Inc., designed for lighting applications with Triac dimming capability. This single-output device operates across a 10.3V to 27V supply range and integrates an internal switch for step-down and step-up topologies. The part is currently in active production status with 3600 units in stock.

Substitute parts are identified when design requirements necessitate alternative sourcing due to supply constraints, end-of-life considerations, or specific application performance needs while maintaining functional equivalence within the allowed electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the MP4032-2GS is based on the following critical parameters that define functional equivalence:

Primary Substitution Criteria:

• AC DC offline switcher topology for lighting applications
• Single output configuration
• Triac dimming capability (primary requirement for direct substitution)
• Surface mount 8-SOIC package compatibility
• Operating temperature range overlap with -40°C minimum
• ROHS3 compliance and active or available product status

Secondary Compatibility Parameters:

• Supply voltage range overlap (minimum 10.3V to 27V envelope)
• Internal switch presence for integrated power conversion
• Step-down and step-up topology support

The substitute parts listed below meet these criteria with varying degrees of parameter alignment. AL9910A-5S-13 provides the closest package and topology match. AL9902S16-13 offers extended supply voltage range but requires package footprint consideration. NCL30030B3DR2G and TPS92001D provide alternative topologies with compatible dimming and temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

AL9910A-5S-13 (Diodes Incorporated): This substitute provides the closest mechanical compatibility with identical 8-SOIC package dimensions and lead count. Both parts support step-down and step-up topologies for lighting applications. The supply voltage range (20V to 500V) encompasses the MP4032-2GS operating envelope. Operating temperature maximum of 85°C (TA) is lower than the MP4032-2GS specification. Dimming capability differs: AL9910A-5S-13 supports analog and PWM dimming versus Triac dimming on the MP4032-2GS. Product status is active with 5400 units in stock. ROHS3 compliance and MSL rating of 1 (Unlimited) are provided.

AL9902S16-13 (Diodes Incorporated): This part offers extended supply voltage range (20V to 500V) and includes internal switch integration. The 16-SOIC package requires PCB layout modification compared to the 8-SOIC MP4032-2GS. Operating temperature range (-40°C to 105°C TA) provides adequate coverage. Dimming supports analog and PWM modes. Product status is active with 1119 units in stock. ROHS3 compliance is confirmed with MSL rating of 3 (168 Hours).

NCL30030B3DR2G (onsemi): This substitute employs Flyback topology rather than step-down/step-up configuration. Supply voltage range (9V to 30V) overlaps the MP4032-2GS specification. The 16-SOIC package (15 leads) requires PCB footprint redesign. Operating temperature range (-40°C to 125°C TJ) matches the MP4032-2GS specification. Dimming capability is not specified. Product status is active with 20100 units in stock. ROHS3 compliance and MSL rating of 1 (Unlimited) are provided.

TPS92001D (Texas Instruments): This part supports Triac dimming, matching the MP4032-2GS dimming requirement. Topology combines Flyback and step-down configurations. Supply voltage maximum of 21V is within the MP4032-2GS range, though minimum is not specified. The 8-SOIC package provides direct mechanical compatibility. Operating temperature range (-40°C to 105°C TJ) provides adequate coverage. Product status is Last Time Buy, indicating limited future availability. ROHS3 compliance and MSL rating of 1 (Unlimited) are provided. Current inventory is 1225 units.

Frequently Asked Questions (FAQ)

Q: Can AL9910A-5S-13 directly replace MP4032-2GS in existing designs?

A: AL9910A-5S-13 shares the 8-SOIC package footprint and supports equivalent topologies. However, dimming capability differs: AL9910A-5S-13 provides analog and PWM dimming while MP4032-2GS uses Triac dimming. Circuit design modifications are required if Triac dimming is a functional requirement. Operating temperature maximum is 85°C (TA) versus 125°C (TJ) for MP4032-2GS.

Q: What is the primary difference between AL9902S16-13 and MP4032-2GS?

A: AL9902S16-13 uses a 16-SOIC package versus the 8-SOIC package of MP4032-2GS, requiring PCB layout changes. AL9902S16-13 includes internal switch integration and supports higher supply voltages (20V to 500V). Dimming modes differ: AL9902S16-13 supports analog and PWM dimming. Both parts are ROHS3 compliant and active products.

Q: Is NCL30030B3DR2G suitable for applications requiring step-down or step-up topology?

A: NCL30030B3DR2G employs Flyback topology, which differs from the step-down and step-up topologies of MP4032-2GS. Flyback topology is suitable for isolated power conversion in lighting applications. The 16-SOIC package (15 leads) requires PCB redesign. Supply voltage range (9V to 30V) overlaps MP4032-2GS specifications.

Q: Why is TPS92001D marked as Last Time Buy?

A: TPS92001D carries a Last Time Buy product status, indicating Texas Instruments has discontinued or will discontinue production. While 1225 units are currently in stock, future availability is limited. This part should be considered only for applications where long-term supply is not critical or as a temporary solution pending transition to active products.

Q: Which substitute part provides the best thermal performance?

A: MP4032-2GS and NCL30030B3DR2G both specify operating temperature to 125°C (TJ), providing the highest thermal rating among the listed parts. AL9902S16-13 operates to 105°C (TA) and AL9910A-5S-13 to 85°C (TA). Thermal performance selection depends on application ambient temperature and power dissipation requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts (AL9910A-5S-13, AL9902S16-13, NCL30030B3DR2G, and TPS92001D) are ROHS3 compliant. All parts also carry REACH Unaffected status and EAR99 ECCN classification, matching the compliance profile of MP4032-2GS.

Q: What packaging considerations apply when selecting a substitute?

A: MP4032-2GS, AL9910A-5S-13, and TPS92001D use 8-SOIC packages with compatible footprints. AL9902S16-13 and NCL30030B3DR2G use 16-SOIC packages, requiring PCB layout modification. Moisture sensitivity levels vary: AL9910A-5S-13, NCL30030B3DR2G, and TPS92001D have MSL 1 (Unlimited), while AL9902S16-13 has MSL 3 (168 Hours), affecting storage and handling requirements.
