Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSL5236TE/1Y is determined by the following critical parameters:

Core Compatibility Criteria:

• Package type: 8-SOIC form factor (0.154", 3.90mm Width)
• Dimming capability: Triac dimming support
• Output configuration: Single output
• Mounting type: Surface Mount
• Application class: AC DC Offline Switcher for LED driver applications
• Regulatory compliance: ROHS3 Compliant

Electrical Performance Boundaries:

• Supply voltage range must accommodate the 9.9V to 16V operating window
• Output current capability must meet or exceed 450mA
• Topology must support Step-Down (Buck) and Step-Up (Boost) configurations

The UCC28810DR from Texas Instruments meets these substitution criteria through identical package geometry, matching Triac dimming functionality, compatible supply voltage specifications, and superior output current rating (750mA), providing design margin for the original 450mA requirement.

Parameter Comparison

Engineering Selection Recommendations

The UCC28810DR qualifies as a direct substitute for the SSL5236TE/1Y based on the following engineering factors:

Package Compatibility: Both devices utilize the 8-SOIC form factor with identical 0.154" (3.90mm) width, ensuring PCB layout compatibility without redesign.

Functional Equivalence: Both ICs provide single-output AC DC offline switching with Triac dimming control, meeting the core application requirements for LED driver circuits.

Regulatory Compliance: The UCC28810DR maintains ROHS3 compliance and MSL 1 (Unlimited) rating, matching the environmental and regulatory standards of the original part.

Supply Voltage: The UCC28810DR maximum supply voltage of 18V exceeds the SSL5236TE/1Y specification of 16V, providing additional design margin within the 9.9V minimum threshold.

Output Current: The UCC28810DR 750mA rating provides 67% additional current capacity over the SSL5236TE/1Y 450mA specification, supporting higher power LED applications without thermal stress.

Product Availability: The UCC28810DR is currently active in production with 3600 units in stock, ensuring supply continuity for discontinued SSL5236TE/1Y designs.

Design Consideration: The UCC28810DR supports additional topologies (Flyback, SEPIC) beyond the original Buck/Boost configuration, offering expanded circuit design flexibility.

Frequently Asked Questions (FAQ)

Q: Can the UCC28810DR replace the SSL5236TE/1Y in existing designs without PCB modification?

A: Yes. Both devices share the 8-SOIC package with identical 0.154" (3.90mm) width and pin-compatible surface mount configuration. Direct footprint substitution is possible without PCB redesign.

Q: What are the key electrical differences between these parts?

A: The UCC28810DR provides higher output current (750mA vs. 450mA) and maximum supply voltage (18V vs. 16V). The UCC28810DR also supports Flyback and SEPIC topologies in addition to Buck/Boost configurations. Operating temperature range differs: SSL5236TE/1Y operates to 160°C (junction), while UCC28810DR operates to 105°C (ambient).

Q: Are both parts Triac dimming compatible?

A: Yes. Both the SSL5236TE/1Y and UCC28810DR include integrated Triac dimming functionality, maintaining compatibility with phase-cut dimming circuits.

Q: What is the supply voltage operating window for substitution?

A: The SSL5236TE/1Y operates from 9.9V to 16V. The UCC28810DR operates from an unspecified minimum to 18V maximum. Designs operating within the 9.9V to 16V window are fully compatible with the substitute part.

Q: Does the UCC28810DR require firmware or software changes?

A: No firmware or software changes are required. Both devices are hardware-based LED driver ICs without programmable logic. Pin-level compatibility enables direct substitution.

Q: What compliance certifications apply to the UCC28810DR?

A: The UCC28810DR is ROHS3 compliant, REACH unaffected, and carries MSL 1 (Unlimited) moisture sensitivity rating, matching the regulatory profile of the SSL5236TE/1Y.

Q: Is the UCC28810DR suitable for high-temperature applications?

A: The UCC28810DR maximum operating temperature is 105°C (ambient). Applications requiring operation above 105°C ambient should evaluate thermal management or alternative parts. The SSL5236TE/1Y supported higher junction temperatures (160°C), which may be relevant for specific thermal designs.
