TLC2933IPWR Phase Lock Loop IC Equivalent & Substitute Parts
Part Overview
The TLC2933IPWR is a Phase Lock Loop (PLL) integrated circuit manufactured by Texas Instruments, designed for clock and timing applications. This device operates at a maximum frequency of 100MHz with CMOS input and output, housed in a 14-TSSOP surface mount package. The TLC2933IPWR is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation
Substitution for the TLC2933IPWR is determined by strict alignment of the following critical parameters:
- Package compatibility: 14-TSSOP surface mount package
- Electrical interface: CMOS input and CMOS output
- Input:Output ratio: 2:1 configuration
- Supply voltage range: 2.85V ~ 5.25V
- Operating temperature range: -20°C ~ 75°C
- Number of circuits: Single circuit configuration
- Compliance certifications: ROHS3 and REACH status
Two substitute parts meet these criteria. The TLC2933AIPWR is the manufacturer-recommended substitute with enhanced frequency capability (110MHz maximum). The TLC2932AIPWR is a parametric equivalent with reduced frequency specification (55MHz maximum) but maintains all other electrical and mechanical compatibility parameters.

Engineering Selection Recommendations
The TLC2933AIPWR is the primary substitute for the obsolete TLC2933IPWR. Both parts maintain identical package geometry, electrical interface specifications, and compliance certifications. The TLC2933AIPWR offers enhanced frequency performance at 110MHz compared to the original 100MHz specification, with active product status ensuring long-term availability and supply chain continuity.
The TLC2932AIPWR serves as a parametric equivalent for applications where the maximum frequency requirement does not exceed 55MHz. This part maintains full mechanical and electrical compatibility within its frequency specification and is also in active production status.
Selection between the two substitutes depends on the maximum frequency requirement of the target application. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
Frequently Asked Questions (FAQ)
Q: Can the TLC2933AIPWR directly replace the TLC2933IPWR in existing designs?
A: Yes. The TLC2933AIPWR maintains identical package dimensions (14-TSSOP), pin configuration, supply voltage range (2.85V ~ 5.25V), operating temperature range (-20°C ~ 75°C), and CMOS input/output interface. The enhanced frequency specification (110MHz vs. 100MHz) provides additional performance margin.
Q: What is the primary difference between the TLC2933AIPWR and TLC2932AIPWR?
A: The maximum operating frequency differs. The TLC2933AIPWR operates to 110MHz, while the TLC2932AIPWR operates to 55MHz. All other electrical and mechanical parameters remain identical. Selection depends on application frequency requirements.
Q: Are both substitute parts available in the same packaging options as the original?
A: Both substitute parts are supplied in 14-TSSOP surface mount packages with identical dimensions (0.173", 4.40mm Width). Packaging format availability (Tape & Reel) may differ from the original Cut Tape option, but the component itself is mechanically identical.
Q: Do the substitute parts meet the same compliance standards as the TLC2933IPWR?
A: Yes. Both TLC2933AIPWR and TLC2932AIPWR are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original part.
Q: Which substitute should be selected for new designs?
A: The TLC2933AIPWR is recommended for new designs due to its active product status and enhanced frequency specification. The TLC2932AIPWR is suitable only if application frequency requirements do not exceed 55MHz.
