MP4060GK LED Driver IC Equivalent & Substitute Parts

Part Overview

The MP4060GK 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 power management IC operates across a 200VAC to 265VAC supply range and is housed in a 10-MSOP package. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating, making it suitable for direct integration into offline LED lighting circuits.

Substitute parts become necessary when the MP4060GK experiences supply constraints, extended lead times, or when design flexibility permits topology or package variations while maintaining functional equivalence for the target application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP4060GK is determined by the following critical parameters:

• Single Output Configuration: All substitute parts must provide exactly one output channel to match the MP4060GK functional requirement.
• AC DC Offline Switcher Classification: Substitute parts must operate as offline switchers, capable of direct mains voltage processing without external isolation transformers.
• Triac Dimming Compatibility: The primary substitute (LM3447MTX/NOPB) maintains Triac dimming to preserve dimmer compatibility. Secondary substitutes (AL9910ASP-13, CPC9909N) support PWM or analog dimming, which requires circuit redesign but maintains offline switching functionality.
• Surface Mount Packaging: All substitutes use surface mount technology, compatible with automated assembly processes.
• RoHS3 and MSL Compliance: All substitutes maintain ROHS3 compliance and MSL Level 1 rating, ensuring environmental and moisture handling equivalence.
• Active Product Status: All listed substitutes maintain active manufacturing status, ensuring long-term availability and supply chain stability.

The substitutes are grouped into two categories: direct Triac-dimming equivalents and functional alternatives with different dimming architectures that require application-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

LM3447MTX/NOPB (Texas Instruments) is the primary substitute for direct replacement in Triac-dimming applications. This part maintains identical Triac dimming functionality and matches the MP4060GK operating temperature range (-40°C to 125°C junction temperature). The 14-TSSOP package requires PCB layout modification compared to the 10-MSOP footprint, but the part is actively manufactured with substantial inventory availability (60,400 units in stock). Full RoHS3 compliance and MSL Level 1 rating ensure equivalent environmental performance.

AL9910ASP-13 (Diodes Incorporated) and CPC9909N (IXYS Integrated Circuits Division) function as offline switchers with PWM or analog dimming architectures. These parts require circuit redesign to replace the Triac dimming interface with PWM or analog control signals. Both parts support wider input voltage ranges (20V–500V and 8V–550V respectively) and operate at higher switching frequencies (25kHz–300kHz and 30kHz–120kHz). These characteristics make them suitable for applications where dimming architecture flexibility exists. Operating temperature ranges are reduced (105°C and 85°C ambient respectively) compared to the MP4060GK. All three substitutes maintain active product status, ROHS3 compliance, and MSL Level 1 rating.

Frequently Asked Questions (FAQ)

Q: Can the LM3447MTX/NOPB replace the MP4060GK without circuit modification?

A: The LM3447MTX/NOPB maintains Triac dimming functionality and offline switcher operation, preserving the core control interface. However, the package change from 10-MSOP to 14-TSSOP requires PCB footprint redesign. Pin-to-pin functional compatibility must be verified against device datasheets before implementation.

Q: What is the primary difference between the MP4060GK and AL9910ASP-13?

A: The MP4060GK uses Triac dimming with a 200VAC–265VAC input range, while the AL9910ASP-13 supports PWM and analog dimming with a 20V–500V input range. The AL9910ASP-13 requires redesign of the dimming control circuit and operates at higher switching frequencies (25kHz–300kHz). The AL9910ASP-13 is suitable only when dimming architecture flexibility exists in the application.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The MP4060GK and all three substitute parts (LM3447MTX/NOPB, AL9910ASP-13, CPC9909N) maintain ROHS3 compliance and MSL Level 1 (unlimited) moisture sensitivity rating, ensuring equivalent environmental and handling requirements.

Q: What is the operating temperature difference between substitutes?

A: The MP4060GK and LM3447MTX/NOPB both operate to 125°C junction temperature. The AL9910ASP-13 operates to 105°C ambient temperature, and the CPC9909N operates to 85°C ambient temperature. Temperature specification differences (junction vs. ambient) must be considered for thermal design validation.

Q: Can CPC9909N be used in place of MP4060GK for lighting applications?

A: The CPC9909N is classified for signage applications and operates to a maximum of 85°C ambient temperature. While it functions as an offline switcher, the reduced temperature rating and different application classification require verification against specific lighting system thermal requirements before substitution.

Q: What packaging considerations apply when substituting these parts?

A: The MP4060GK uses a 10-MSOP package (0.118" width). The LM3447MTX/NOPB uses 14-TSSOP (0.173" width), and both AL9910ASP-13 and CPC9909N use 8-SOIC packages (0.154" width). All are surface mount, but PCB layout and footprint redesign is required for any substitution. The AL9910ASP-13 includes an exposed pad for thermal management, which may affect layout considerations.
