Parameter Comparison

Engineering Selection Recommendations

The LT3065MPMSE#TRPBF is the direct substitute for the obsolete LT3065MPMSE#TR. Both components share identical electrical specifications, functional capabilities, and physical packaging requirements, ensuring drop-in compatibility at the circuit board level.

Product Status Consideration: The LT3065MPMSE#TR is classified as Obsolete, while the LT3065MPMSE#TRPBF maintains Active product status. Selection of the Active variant ensures long-term supply chain availability and continued manufacturer support.

Compliance & Certification: The LT3065MPMSE#TRPBF carries ROHS3 Compliance and REACH Unaffected certifications. These regulatory designations confirm adherence to current environmental and hazardous substance restrictions applicable to electronic components in regulated markets.

Control Features Enhancement: The LT3065MPMSE#TRPBF includes Current Limit as an additional control feature beyond the base Enable, Power Good, and Soft Start functions present in the original part. This enhancement provides supplementary circuit protection without compromising functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the LT3065MPMSE#TRPBF be used as a direct replacement for the LT3065MPMSE#TR?

A: Yes. Both components deliver identical electrical performance across all critical parameters including output voltage range (0.6V to 40V), output current (500mA), dropout voltage (0.51V @ 500mA), and operating temperature range (-55°C to 150°C). Physical packaging is identical (12-TSSOP with Exposed Pad). No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and regulatory compliance. The LT3065MPMSE#TR is Obsolete, while the LT3065MPMSE#TRPBF is Active. The substitute part includes ROHS3 Compliance and REACH Unaffected certifications. The LT3065MPMSE#TRPBF also includes Current Limit as an additional control feature. Electrical performance and package specifications remain identical.

Q: Are there packaging differences between these parts?

A: No. Both parts use the 12-TSSOP (0.118", 3.00mm Width) Exposed Pad package configuration with 12-MSOP-EP supplier device package designation. Moisture sensitivity level is identical at MSL 1 (Unlimited). Board layout and assembly processes require no modification.

Q: Why should I select the LT3065MPMSE#TRPBF over the obsolete part?

A: The LT3065MPMSE#TRPBF maintains Active product status, ensuring continued availability from Analog Devices Inc. and authorized distributors.
