Functional Category: Both components operate within the Power Management (PMIC) category as linear voltage regulators.

Product Status Transition: The TL1963ADCQR maintains Active product status, providing long-term availability and supply security compared to the Last Time Buy designation of the LP1763DR.

Electrical Performance Parameters: The TL1963ADCQR delivers 1.5A output current, adjustable output voltage range (1.21V to 20V), and maximum input voltage of 20V, supporting equivalent application requirements.

Packaging Compatibility: Both components utilize surface mount technology, maintaining PCB layout and assembly process compatibility.

Parameter Comparison

Engineering Selection Recommendations

Supply Chain Continuity: The LP1763DR is designated Last Time Buy, indicating discontinued production. The TL1963ADCQR, maintaining Active product status from the same manufacturer, ensures uninterrupted component availability for ongoing production and field support requirements.

Regulatory Alignment: Both components satisfy ROHS3 compliance requirements, eliminating regulatory substitution barriers for applications subject to environmental directives.

Manufacturer Support: Texas Instruments' continued active support of the TL1963ADCQR provides access to technical documentation, application notes, and design resources essential for engineering validation.

Moisture Handling: The LP1763DR MSL 1 rating permits unlimited shelf life without moisture control. The TL1963ADCQR MSL 2 rating requires one-year moisture control protocols, necessitating appropriate storage and handling procedures during component procurement and assembly operations.

Packaging Standardization: Both components employ surface mount technology, maintaining compatibility with existing PCB assembly processes and equipment configurations.

Frequently Asked Questions (FAQ)

Q: Can the TL1963ADCQR directly replace the LP1763DR in existing designs?

A: The TL1963ADCQR is the manufacturer-recommended substitute. Both components are Texas Instruments products with ROHS3 compliance and surface mount packaging. Design validation should confirm electrical parameter compatibility with specific application requirements, particularly output voltage configuration and current delivery specifications.

Q: What is the significance of the Last Time Buy status for the LP1763DR?

A: Last Time Buy designation indicates Texas Instruments has discontinued production of the LP1763DR. This status requires design migration to alternative components for new production runs and long-term supply security. The TL1963ADCQR provides the recommended transition path.

Q: How does the MSL rating difference affect component handling?

A: The LP1763DR MSL 1 rating permits unlimited shelf storage without moisture control measures. The TL1963ADCQR MSL 2 rating requires storage within controlled humidity environments and limits shelf life to one year from manufacturing date. Procurement and assembly operations must implement appropriate moisture management protocols for the substitute component.

Q: Are there packaging differences between these components?

A: The TL1963ADCQR is specified in SOT-223-6 package format with Cut Tape and Digi-Reel packaging options. Both components utilize surface mount technology, maintaining PCB layout compatibility. Verify specific package dimensions against PCB footprint requirements during design transition.

Q: What electrical parameters should be validated during substitution?

A: The TL1963ADCQR provides 1.5A output current, adjustable output voltage (1.21V to 20V), and 20V maximum input voltage. Confirm these specifications align with application requirements for output current demand, voltage regulation range, and input supply voltage levels.
