SSL5237TE/1Y LED Driver IC Equivalent & Substitute Parts

Part Overview

The SSL5237TE/1Y is an LED Driver IC manufactured by NXP USA Inc., designed for AC DC offline switching applications with integrated triac dimming capability. This component functions as a 1-output offline switcher supporting both step-down (buck) and step-up (boost) topologies, rated for 800mA output current and operating across a 9.9V to 16V supply range.

The SSL5237TE/1Y is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Substitute Part Grouping Explanation

Substitution eligibility for the SSL5237TE/1Y is determined by the following critical parameters:

• Package Compatibility: Both parts must use 8-SOIC surface mount packaging to ensure PCB layout compatibility
• Topology Support: Substitute must support AC DC offline switching with step-down and step-up capability
• Output Configuration: Single output requirement
• Supply Voltage Range: Substitute voltage range must encompass or overlap the original 9.9V to 16V specification
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status required for equivalent substitution

The TPS92074DR from Texas Instruments meets these core substitution criteria through matching package form factor, offline switcher topology, single-output configuration, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

The TPS92074DR qualifies as a functional substitute based on the following engineering criteria:

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for equivalent component selection.

Product Availability: The TPS92074DR maintains active product status with 5274 units in stock, providing immediate availability compared to the discontinued SSL5237TE/1Y.

Package Compatibility: Both components use identical 8-SOIC surface mount packaging with 0.154" width, enabling direct PCB layout compatibility without redesign.

Functional Topology: Both parts support AC DC offline switching with step-down and step-up topologies and single-output configuration, maintaining circuit functionality.

Supply Voltage Consideration: The TPS92074DR supply range (11V to 18V) overlaps the SSL5237TE/1Y range (9.9V to 16V) across the 11V to 16V window. Applications operating below 11V require design verification.

Temperature Rating Difference: The SSL5237TE/1Y operates to 160°C junction temperature while the TPS92074DR operates to 125°C. Applications requiring operation above 125°C require alternative component selection.

Frequently Asked Questions (FAQ)

Q: Can the TPS92074DR directly replace the SSL5237TE/1Y on existing PCBs?

A: Yes, for applications within the overlapping supply voltage range (11V to 16V) and operating temperature range (-40°C to 125°C). The identical 8-SOIC package enables direct PCB compatibility without layout modification.

Q: What is the minimum supply voltage difference between these parts?

A: The SSL5237TE/1Y operates from 9.9V minimum while the TPS92074DR operates from 11V minimum. Designs operating between 9.9V and 11V require alternative component selection or circuit redesign.

Q: Are there temperature limitations when substituting?

A: Yes. The TPS92074DR maximum junction temperature is 125°C compared to the SSL5237TE/1Y at 160°C. Applications requiring operation above 125°C cannot use the TPS92074DR as a substitute.

Q: Do both parts support the same dimming functionality?

A: The SSL5237TE/1Y specifies triac dimming capability. The TPS92074DR dimming specification is not provided in the available parameters. Dimming compatibility requires datasheet verification before substitution.

Q: What packaging format is available for the TPS92074DR?

A: The TPS92074DR is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The SSL5237TE/1Y packaging format is not specified in the available parameters.
