Substitute Part Grouping Explanation

Substitution for the TLC5916IPWRG4 is determined by strict equivalence across the following critical parameters:

• Topology & Function: Shift register-based linear LED driver with 8 outputs
• Electrical Specifications: 3V–5.5V supply range, 120mA per-channel output, 20V output voltage, 30MHz frequency
• Package: 16-TSSOP form factor with identical pinout and mechanical dimensions
• Compliance: ROHS3 compliance and MSL Level 1 rating
• Operating Range: -40°C to 125°C ambient temperature

The TLC5916IPWR and TLC5917IPWR meet all substitution criteria. The TLC5916IPWR is the manufacturer-recommended direct replacement, maintaining identical base product specifications. The TLC5917IPWR is a parametric equivalent offering the same electrical and mechanical characteristics with an alternative base product designation.
