TCR3DM105,LF(SE Linear Voltage Regulator

Part Overview

The TCR3DM105,LF(SE is an active linear voltage regulator IC manufactured by Toshiba Semiconductor and Storage. This positive fixed output regulator delivers 300mA output current with a fixed 1.05V output voltage and operates across an input voltage range up to 5.5V. The device integrates over-current and over-temperature protection features with an enable control function. The part is housed in a 4-UDFN exposed pad surface mount package and is RoHS3 compliant with MSL 1 moisture sensitivity rating. Identification of equivalent and substitute parts is necessary to address supply chain continuity, inventory optimization, and design flexibility while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TCR3DM105,LF(SE is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Output configuration (Positive)
• Output type (Fixed)
• Number of regulators (1)
• Maximum input voltage (5.5V)
• Fixed output voltage (1.05V)
• Maximum dropout voltage (0.75V @ 300mA)
• Output current capability (300mA)
• Control features (Enable function)
• Protection features (Over Current, Over Temperature)
• Operating temperature range (-40°C to 85°C)

Mechanical Equivalence Criteria:

• Mounting type (Surface Mount)
• Package type (4-UDFN Exposed Pad)
• Supplier device package (4-DFN 1x1)

Compliance Criteria:

• RoHS compliance status
• Moisture sensitivity level (MSL 1)

The substitute part TCR3DM105,LF meets all electrical and mechanical equivalence criteria. The primary difference is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is available in Cut Tape (CT) format. Both parts share the identical base product number TCR3DM105 and are manufactured by Toshiba Semiconductor and Storage.

Parameter Comparison

Engineering Selection Recommendations

The TCR3DM105,LF substitute part is electrically and mechanically equivalent to the TCR3DM105,LF(SE main part. Both devices are active products manufactured by Toshiba Semiconductor and Storage with identical electrical specifications, protection features, and package geometry.

Selection Basis:

The primary distinction between the main part and substitute is the supply packaging format. The main part TCR3DM105,LF(SE is supplied in Tape & Reel (TR) format, suitable for high-volume automated assembly operations. The substitute TCR3DM105,LF is supplied in Cut Tape (CT) format, appropriate for lower-volume applications or manual assembly processes.

Both parts maintain RoHS compliance and MSL 1 moisture sensitivity rating, ensuring compatibility with standard PCB assembly and storage protocols. The electrical performance, thermal characteristics, and functional capabilities are identical across both packaging formats.

Selection between these parts should be based on procurement requirements, assembly methodology, and inventory management practices rather than technical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can TCR3DM105,LF (Cut Tape) be used as a direct replacement for TCR3DM105,LF(SE (Tape & Reel)?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. Cut Tape format is suitable for applications where Tape & Reel format is not required.

Q: Are there any electrical performance differences between the two parts?

A: No. Both parts deliver identical electrical performance: 300mA output current, 1.05V fixed output voltage, 0.75V maximum dropout voltage at 300mA, and identical protection features (over-current and over-temperature).

Q: Do both parts have the same package dimensions?

A: Yes. Both parts use the 4-UDFN Exposed Pad package with 1x1mm dimensions. PCB footprints and assembly processes are identical.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) format supplies components on continuous carrier tape wound on reels, optimized for high-speed automated pick-and-place assembly. Cut Tape (CT) format supplies components on cut segments of carrier tape, suitable for lower-volume or manual assembly operations.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are RoHS compliant. The main part is RoHS3 compliant, and the substitute is RoHS compliant. Both meet environmental and regulatory requirements.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture sensitivity restrictions for storage and handling.

Q: Can these parts be used interchangeably in production?

A: Yes, provided the assembly process accommodates the packaging format. Tape & Reel format requires automated reel-fed equipment, while Cut Tape format is compatible with manual or semi-automated assembly.

Q: Are there any thermal or performance differences between the packaging formats?

A: No. The thermal characteristics and electrical performance are identical. Packaging format does not affect device performance.
