Substitute Part Grouping Explanation

Substitute parts for the MP4060GK-Z are identified based on the following criteria:

Primary Substitution Parameters:

Device Type: AC DC Offline Switcher
Number of Outputs: 1
Applications: Lighting
RoHS Compliance: ROHS3 Compliant
Product Status: Active
Operating Temperature Range: -40°C minimum and 125°C maximum capability

Topology Consideration: The MP4060GK-Z employs Buck and Boost topologies. Substitute parts may employ alternative topologies (Flyback, Step-Down/Step-Up) provided they maintain AC DC offline switching functionality for lighting applications.

Dimming Capability: The main part supports Triac dimming. Substitute parts with Analog or PWM dimming capabilities are acceptable as these represent alternative dimming control methods suitable for offline LED driver applications.

Package Compatibility: Surface mount packages with equivalent or smaller footprints are acceptable. The main part uses 10-MSOP packaging; substitutes in 8-SOIC or 8-SO-EP packages are viable alternatives.

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance, meeting regulatory and supply chain continuity requirements equivalent to the MP4060GK-Z.

AL9910A-5SP-13 (Diodes Incorporated): This part operates across a wider input voltage range (20V to 500V) compared to the main part's AC input specification. It supports both Analog and PWM dimming methods and is rated to 105°C ambient temperature, which is 20°C lower than the main part's junction temperature rating. Package footprint is 8-SOIC with exposed pad, requiring PCB layout adjustment from the 10-MSOP main part.

TPS92310DGS/NOPB (Texas Instruments): This part matches the 10-MSOP package footprint of the main part and maintains the full -40°C to 125°C operating temperature range. Input voltage range is 13V to 36V DC, representing a different supply specification than the main part's AC input. Topology is Flyback rather than Buck/Boost.

TPS92314DR/NOPB (Texas Instruments): This part operates within -40°C to 125°C temperature range matching the main part. Input voltage range is 13V to 35V DC. Package is 8-SOIC, requiring PCB layout modification. Topology is Flyback. Applications explicitly include Lighting.

Frequently Asked Questions (FAQ)

Q: Can AL9910A-5SP-13 directly replace MP4060GK-Z on the same PCB?

A: No. AL9910A-5SP-13 uses an 8-SOIC package with exposed pad, while MP4060GK-Z uses 10-MSOP. PCB layout and footprint redesign is required. Additionally, the input voltage specification differs (20V-500V DC versus 200-265VAC).

Q: What is the primary difference between TPS92310DGS/NOPB and TPS92314DR/NOPB?

A: TPS92310DGS/NOPB uses 10-VSSOP packaging and has no specified dimming capability. TPS92314DR/NOPB uses 8-SOIC packaging and explicitly lists Lighting applications. Both employ Flyback topology and operate at 13V-36V and 13V-35V input ranges respectively.

Q: Are the substitute parts suitable for 200-265VAC input applications?

A: No. All substitute parts listed operate on DC input voltages (13V-36V or 20V-500V range). The MP4060GK-Z is specifically designed for direct AC input (200-265VAC). Substitution requires AC-to-DC conversion stage redesign.

Q: Does operating temperature rating affect substitution suitability?

A: AL9910A-5SP-13 is rated to 105°C ambient temperature, which is lower than the main part's 125°C junction temperature rating. TPS92310DGS/NOPB and TPS92314DR/NOPB both match the 125°C rating. Temperature derating must be evaluated for specific application thermal conditions.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 Compliant status, matching the main part's regulatory compliance.
