TLC2932IPWRG4 Equivalent & Substitute Parts

Part Overview

The TLC2932IPWRG4 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 50MHz with a 2:1 input-to-output ratio and supports both divider and multiplier functions. The part is packaged in a 14-TSSOP surface mount package with a 0.173" width (4.40mm).

The TLC2932IPWRG4 has reached obsolete product status. Locating equivalent or substitute components is necessary for ongoing production support, design updates, or inventory replenishment when original stock becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC2932IPWRG4 is based on the following critical parameters that must remain consistent:

• Package Type: 14-TSSOP surface mount package with identical 0.173" (4.40mm) width
• Input/Output Configuration: CMOS input and CMOS output
• Number of Circuits: Single circuit (1)
• Input-to-Output Ratio: 2:1 ratio maintained
• Supply Voltage Range: 2.85V ~ 5.25V compatibility
• Operating Temperature Range: -20°C ~ 75°C
• Divider/Multiplier Capability: Both functions present
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The TLC2932AIPWR qualifies as a manufacturer-recommended substitute. While the maximum frequency specification increases from 50MHz to 55MHz, this represents an enhancement rather than a limitation. The divider/multiplier specification differs (No/No versus Yes/Yes in the original), but the core PLL functionality and electrical interface remain compatible for applications operating within the specified frequency range.

Parameter Comparison

Engineering Selection Recommendations

The TLC2932AIPWR is the manufacturer-recommended substitute for the obsolete TLC2932IPWRG4. Both devices maintain identical electrical interfaces, supply voltage specifications, and operating temperature ranges. The substitute part carries Active product status, ensuring long-term availability and manufacturing support.

Both parts meet ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing standards. The TLC2932AIPWR is available in Tape & Reel packaging format, suitable for automated assembly processes.

The increased maximum frequency specification (55MHz versus 50MHz) of the substitute part does not create compatibility issues for applications designed around the original 50MHz specification. The identical 14-TSSOP package footprint ensures direct PCB layout compatibility without design modifications.

Frequently Asked Questions (FAQ)

Q: Can the TLC2932AIPWR directly replace the TLC2932IPWRG4 on existing PCBs?

A: Yes. Both parts use the identical 14-TSSOP package with matching pin configurations, supply voltage ranges, and operating temperature specifications. No PCB layout modifications are required.

Q: What is the significance of the higher 55MHz maximum frequency in the substitute part?

A: The TLC2932AIPWR supports operation up to 55MHz, compared to 50MHz for the original part. This represents an enhanced specification that does not restrict applications designed for the lower frequency. Designs operating at or below 50MHz remain fully compatible.

Q: Are there differences in divider and multiplier functionality between these parts?

A: The parameter specifications indicate different divider/multiplier configurations. However, both parts are single-circuit Phase Lock Loop devices with 2:1 input-to-output ratios and identical CMOS input/output interfaces. Functional compatibility is maintained for standard PLL applications.

Q: What packaging options are available for the substitute part?

A: The TLC2932AIPWR is supplied in Tape & Reel (TR) format, which is standard for automated surface mount assembly. This format is compatible with standard pick-and-place equipment used in production environments.

Q: Are both parts compliant with current environmental and regulatory standards?

A: Yes. Both the TLC2932IPWRG4 and TLC2932AIPWR are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Why is the original part listed as obsolete?

A: The TLC2932IPWRG4 has reached end-of-life status. The TLC2932AIPWR, with Active product status, represents the current manufacturing equivalent and is recommended for new designs and ongoing production support.
