LT3055MPMSE#TR Equivalent & Substitute Parts

Part Overview

The LT3055MPMSE#TR is a linear voltage regulator IC from Analog Devices Inc. designed for positive adjustable output applications. This device delivers 500mA output current with a wide input voltage range up to 45V and adjustable output voltage from 0.6V to 40V. The regulator integrates protection features including over-current, over-temperature, and reverse polarity protection, along with control features such as enable, power good, and soft start functionality.

The LT3055MPMSE#TR is classified as obsolete. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support long-term product availability for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LT3055MPMSE#TR are identified based on strict electrical and mechanical parameter equivalence. The following criteria determine substitution eligibility:

Electrical Parameters:

• Output configuration (Positive)
• Output type (Adjustable)
• Number of regulators (1)
• Voltage specifications: Input maximum 45V, output range 0.6V to 40V
• Current output capacity (500mA)
• Operating temperature range (-55°C ~ 150°C)

Mechanical Parameters:

• Package type (16-TFSOP with exposed pad)
• Mounting type (Surface Mount)
• Supplier device package (16-MSOP-EP)

Compliance Parameters:

• Moisture sensitivity level (MSL 1)
• ECCN classification (EAR99)
• HTSUS code (8542.39.0001)

Substitute parts must match all electrical and mechanical parameters without exception. Variations in product status, packaging format (tape & reel vs. bulk), or compliance certifications do not disqualify a part from substitution eligibility when core functional parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

The LT3055MPMSE#TRPBF is a direct functional equivalent to the LT3055MPMSE#TR. Both parts share identical electrical specifications, mechanical packaging, and core protection features. The primary distinction is product status: the LT3055MPMSE#TR is classified as obsolete, while the LT3055MPMSE#TRPBF maintains active status from the manufacturer.

For new designs or production continuity, the LT3055MPMSE#TRPBF is the appropriate selection. This part is currently manufactured and stocked, ensuring long-term availability and supply chain stability. The LT3055MPMSE#TRPBF carries RoHS3 compliance and REACH unaffected status, meeting modern regulatory requirements for electronic components.

The packaging format difference (tape & reel for the substitute versus bulk for the original) does not affect electrical or mechanical compatibility. Both formats contain identical die and internal circuitry. Selection between these parts should be based on procurement requirements, inventory management practices, and manufacturing process specifications.

Frequently Asked Questions (FAQ)

Q: Can the LT3055MPMSE#TRPBF be used as a direct replacement for the LT3055MPMSE#TR?

A: Yes. Both parts are electrically and mechanically identical. They share the same output voltage range (0.6V to 40V), output current (500mA), input voltage rating (45V maximum), operating temperature range (-55°C to 150°C), and package type (16-TFSOP with exposed pad). The LT3055MPMSE#TRPBF is the active production equivalent.

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

A: The primary difference is product lifecycle status. The LT3055MPMSE#TR is obsolete, while the LT3055MPMSE#TRPBF is actively manufactured. Additionally, the substitute part is supplied in tape & reel packaging format, whereas the original may be supplied in bulk. The "#TRPBF" suffix indicates tape & reel packaging with lead-free (Pb-free) termination. Electrical performance and physical dimensions are identical.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. Both parts use the 16-MSOP-EP package with identical pinout, footprint, and thermal characteristics. PCB layouts, schematic connections, and application circuits require no modification. The parts are pin-for-pin and functionally equivalent.

Q: Does the LT3055MPMSE#TRPBF meet current regulatory standards?

A: Yes. The LT3055MPMSE#TRPBF is RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components in most jurisdictions.

Q: What is the significance of the MSL rating?

A: Both parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture bake-out requirements. This simplifies inventory management and reduces handling constraints during storage and transportation.

Q: Can these parts be used interchangeably in existing production?

A: Yes. The electrical specifications, mechanical dimensions, and performance characteristics are identical. Existing designs, PCB layouts, and test procedures require no modification. The parts are suitable for direct substitution in manufacturing processes.
