IMX111J-TL Equivalent & Substitute Parts

Part Overview

The IMX111J-TL is an active LED driver controller IC manufactured by Power Integrations, part of the InnoSwitch™3-MX series. This device functions as a 2-output DC-DC controller with flyback topology, designed for LED backlight applications. The IC integrates an internal switch and supports both analog and PWM dimming control, operating from a 4.75V to 5.25V supply with output voltage range of 3V to 22V. The component is housed in a 28-QFN (5x5) surface mount package with exposed pad.

The IMX111J-TL maintains active product status with full RoHS compliance and REACH unaffected designation. Substitute parts are identified based on functional equivalence within the InnoSwitch™3-MX series, where alternative configurations may serve equivalent applications while maintaining core electrical and mechanical compatibility parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IMX111J-TL is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: Power Integrations
• Series: InnoSwitch™3-MX
• Package / Case: 28-WFQFN Exposed Pad
• Supplier Device Package: 28-QFN (5x5)
• Mounting Type: Surface Mount
• Voltage - Supply (Min): 4.75V
• Voltage - Supply (Max): 5.25V
• Voltage - Output: 3V ~ 22V
• Dimming: Analog, PWM
• Operating Temperature: -40°C ~ 150°C (TJ)
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level (MSL): 3 (168 Hours)

Variable Parameters Allowing Substitution:

• Number of Outputs: The IMX111J-TL features 2 outputs, while substitute parts may feature alternative output configurations within the same series
• Base Product Number: Variations within the InnoSwitch™3-MX family

The IMX101J-TL qualifies as a parametric equivalent based on matching all mandatory parameters while differing only in the number of outputs (1 output versus 2 outputs).

Parameter Comparison

Engineering Selection Recommendations

Both the IMX111J-TL and IMX101J-TL maintain active product status within the Power Integrations portfolio, ensuring continued availability and manufacturing support. Both components carry full RoHS compliance certification and REACH unaffected designation, meeting regulatory requirements for industrial and consumer applications.

Selection between these parts is determined by output channel requirements. The IMX111J-TL provides 2-output capability, while the IMX101J-TL provides 1-output capability. All other electrical characteristics, thermal performance, supply voltage specifications, and package dimensions remain identical.

Both components are manufactured in the same 28-QFN (5x5) surface mount package with exposed pad, ensuring identical PCB footprint and thermal management characteristics. The identical operating temperature range (-40°C to 150°C junction temperature) and moisture sensitivity level (MSL 3, 168 hours) apply to both variants.

Frequently Asked Questions (FAQ)

Q: Can the IMX101J-TL directly replace the IMX111J-TL in an existing design?

A: Direct replacement is possible only if the application requires single-output LED driver functionality. The IMX101J-TL provides 1 output channel versus the IMX111J-TL's 2 output channels. If the design utilizes both output channels of the IMX111J-TL, the IMX101J-TL cannot serve as a direct substitute without circuit redesign.

Q: Are the PCB footprints identical between IMX111J-TL and IMX101J-TL?

A: Yes. Both components use the 28-QFN (5x5) package with exposed pad designation (28-WFQFN). The physical footprint, pin count, and pad layout are identical, allowing for same-footprint substitution at the PCB level.

Q: Do both parts support the same supply voltage range?

A: Yes. Both the IMX111J-TL and IMX101J-TL operate from identical supply voltage specifications: 4.75V minimum to 5.25V maximum. Output voltage range is also identical: 3V to 22V.

Q: Are dimming capabilities the same across both parts?

A: Yes. Both components support identical dimming modes: analog and PWM dimming. Dimming control circuitry and signal requirements are equivalent between the two parts.

Q: What is the primary difference between these two parts?

A: The primary difference is the number of integrated output channels. The IMX111J-TL integrates 2 independent output channels, while the IMX101J-TL integrates 1 output channel. All other specifications, including topology, package, thermal range, and compliance certifications, are identical.

Q: Do both parts have the same thermal characteristics?

A: Yes. Both components operate across the identical temperature range of -40°C to 150°C junction temperature and carry the same Moisture Sensitivity Level (MSL 3, 168 hours), ensuring equivalent thermal performance and handling requirements.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both the IMX111J-TL and IMX101J-TL carry identical compliance certifications: RoHS Compliant status and REACH Unaffected designation. Both maintain active product status with Power Integrations.
