Key Parameters

Substitute Part Grouping Explanation

Substitute components for the TLC2932IPWR must maintain compatibility across the following critical parameters:

Electrical Compatibility:

• Package type: 14-TSSOP surface mount configuration
• Input/Output signal type: CMOS
• Supply voltage range: 2.85V ~ 5.25V
• Operating temperature range: -20°C ~ 75°C
• Circuit configuration: Single PLL circuit with 2:1 input-to-output ratio

Regulatory & Environmental Compliance:

• RoHS3 compliance status
• Moisture sensitivity level (MSL 1 - Unlimited)
• REACH compliance status

The TLC2932AIPWR qualifies as a direct substitute based on identical package, electrical interface, supply voltage, operating temperature range, and regulatory compliance. The increased maximum frequency specification (55MHz versus 50MHz) represents an enhanced capability that maintains backward compatibility with the original design requirements.

Parameter Comparison

Engineering Selection Recommendations

The TLC2932AIPWR is the manufacturer-recommended substitute for the obsolete TLC2932IPWR. Both components share identical electrical specifications, package geometry, and regulatory compliance certifications. The TLC2932AIPWR maintains active product status with Texas Instruments, ensuring long-term availability and supply chain continuity.

The TLC2932AIPWR's maximum frequency specification of 55MHz exceeds the original 50MHz requirement, providing operational margin without introducing compatibility concerns. The identical supply voltage range, operating temperature specifications, and CMOS signal interface ensure direct functional equivalence in existing circuit designs.

For applications requiring the original TLC2932IPWR, the TLC2932AIPWR provides a qualified replacement path with enhanced performance characteristics and confirmed availability.

Frequently Asked Questions (FAQ)

Q: Can the TLC2932AIPWR directly replace the TLC2932IPWR in existing designs?

A: Yes. The TLC2932AIPWR maintains identical electrical interface specifications, package dimensions, supply voltage requirements, and operating temperature range. No circuit modifications are required for substitution.

Q: What is the significance of the higher 55MHz frequency specification in the TLC2932AIPWR?

A: The increased maximum frequency represents an enhanced capability specification. Applications designed for the original 50MHz specification operate within the TLC2932AIPWR's performance envelope, ensuring backward compatibility.

Q: Are there differences in packaging between these components?

A: Both components use the 14-TSSOP surface mount package with identical dimensions (0.173", 4.40mm Width). The TLC2932AIPWR is available in Tape & Reel (TR) packaging format, which is standard for production quantities.

Q: Do both components meet the same regulatory compliance standards?

A: Yes. Both the TLC2932IPWR and TLC2932AIPWR are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Why is the TLC2932IPWR classified as obsolete?

A: Product obsolescence reflects Texas Instruments' lifecycle management. The TLC2932AIPWR represents the active continuation of this product line with equivalent functionality and enhanced specifications.
