TLC69614RTWR Equivalent & Substitute Parts
Part Overview
The TLC69614RTWR is a 16-output LED driver IC manufactured by Texas Instruments, designed for mini-LED matrix local dimming applications in backlight systems. This linear constant current device operates across a 3V to 5.5V supply range with 60mA per-channel output capability and PWM dimming control. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).
Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the TLC696x series, allowing for design flexibility and supply chain alternatives while preserving circuit functionality.

Engineering Selection Recommendations
All three parts—TLC69614RTWR, TLC69612RTWR, and TLC69611RTWR—are active production components from Texas Instruments with identical ROHS3 compliance and REACH unaffected status. Selection between these parts is determined by application-specific LED matrix requirements rather than electrical performance differences.
The TLC69614RTWR supports 64 mini-LED matrix configurations, the TLC69612RTWR supports 32 mini-LED matrix configurations, and the TLC69611RTWR provides general mini-LED local dimming backlight functionality. All maintain equivalent electrical specifications, thermal operating ranges, and packaging standards.
Parts are available in Tape & Reel packaging with MSL 1 rating, suitable for automated assembly processes without moisture sensitivity constraints.
Frequently Asked Questions (FAQ)
Q: Can TLC69612RTWR or TLC69611RTWR be used as direct replacements for TLC69614RTWR?
A: Yes, from an electrical and mechanical standpoint. All three parts share identical output count (16), supply voltage range (3V–5.5V), output voltage (20V), per-channel current (60mA), dimming method (PWM), package type (24-WFQFN), and operating temperature range (-40°C to 85°C). Selection depends on the specific LED matrix configuration required by the application.
Q: What is the difference between these three part numbers?
A: The primary difference is the internal LED matrix configuration. TLC69614RTWR is designed for 64 mini-LED matrix applications, TLC69612RTWR for 32 mini-LED matrix applications, and TLC69611RTWR for general mini-LED local dimming. Electrical performance and pinout remain identical.
Q: Are all three parts available in the same packaging?
A: Yes. All three parts are supplied in 24-WFQFN (4x4) Exposed Pad packages with Tape & Reel (TR) packaging, suitable for surface mount assembly.
Q: Do these parts have the same compliance certifications?
A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification with identical HTSUS code 8542.39.0001.
Q: What is the moisture sensitivity rating for these parts?
A: All three parts have MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage or handling.
