R1180N331C-TR-YE Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The R1180N331C-TR-YE is an active linear voltage regulator IC manufactured by Nisshinbo Micro Devices Inc. This positive fixed output regulator delivers 3.3V at 150mA output current in a surface mount SOT-23-5 package. The device is designed for applications requiring low-dropout voltage regulation with integrated over-current protection.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set. The R1180N331C-TR-YE has direct parametric equivalents available from the same manufacturer series, differing primarily in packaging supplier designation and control feature configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R1180N331C-TR-YE is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Output voltage fixed at 3.3V
• Output current capability of 150mA
• Maximum input voltage of 6V
• Dropout voltage maximum of 0.4V at 150mA
• Quiescent current of 1.5µA
• Over-current protection feature
• Operating temperature range -40°C to 85°C

Mechanical Equivalence Requirements:

• SOT-23-5 package (SC-74A, SOT-753)
• Surface mount configuration
• Tape & Reel packaging format

Compliance Requirements:

• RoHS compliance status
• Moisture Sensitivity Level 1 (Unlimited)

The identified substitute parts maintain all electrical and mechanical parameters. Variations in control features (Enable function presence) and RoHS certification revision level do not affect core substitution eligibility, as these represent functional enhancements or updated compliance certifications rather than parameter deviations.

Parameter Comparison

Engineering Selection Recommendations

R1180N331B-TR-FE is a direct substitute with identical electrical and mechanical specifications. This part includes an additional Enable control feature not present in the R1180N331C-TR-YE. The Enable function provides circuit-level power management capability. Both parts maintain RoHS compliance, with R1180N331B-TR-FE certified to ROHS3 standard. Selection of this substitute is appropriate when Enable functionality is required or when ROHS3 certification is mandated by procurement specifications.

R1180N331C-TR-FE is a direct substitute with identical electrical and mechanical specifications to the R1180N331C-TR-YE. This part differs only in packaging supplier designation (FE versus YE suffix). Both parts lack the Enable control feature and maintain equivalent RoHS compliance status (ROHS3 for the substitute). Selection of this substitute is appropriate for direct replacement when packaging supplier designation is not a constraint.

All three parts share identical core performance parameters: 3.3V fixed output, 150mA current capacity, 0.4V maximum dropout voltage, and SOT-23-5 package configuration. All parts are active products with current manufacturing status and unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can R1180N331B-TR-FE replace R1180N331C-TR-YE in existing designs?

A: Yes. The R1180N331B-TR-FE maintains all electrical output specifications (3.3V, 150mA, 0.4V dropout) and mechanical package configuration (SOT-23-5). The additional Enable control feature does not prevent substitution; it represents a functional enhancement. If the Enable pin is not used in the circuit, the part operates identically to the original.

Q: What is the difference between the YE and FE packaging designations?

A: The YE and FE suffixes indicate different packaging supplier designations. Both R1180N331C-TR-YE and R1180N331C-TR-FE are identical in electrical performance and physical package type (SOT-23-5). The suffix reflects the supplier of the tape and reel packaging material, not the semiconductor die or performance characteristics.

Q: Are all three parts RoHS compliant?

A: Yes. R1180N331C-TR-YE is RoHS Compliant. R1180N331B-TR-FE and R1180N331C-TR-FE are both ROHS3 Compliant. ROHS3 represents an updated certification standard that supersedes earlier RoHS compliance levels. All three parts meet RoHS environmental requirements.

Q: Does the Enable feature in R1180N331B-TR-FE affect circuit operation if not used?

A: No. If the Enable pin is not connected or is tied to the appropriate logic level in the circuit design, the R1180N331B-TR-FE operates with identical output regulation characteristics to the R1180N331C-TR-YE. The Enable feature is optional functionality that does not alter core regulator performance.

Q: Are the dropout voltage and quiescent current specifications identical across all three parts?

A: Yes. All three parts specify 0.4V maximum dropout voltage at 150mA output current and 1.5µA quiescent current. These parameters are identical and determine equivalent thermal performance and power efficiency in the application circuit.

Q: What is the operating temperature range for all substitute parts?

A: All three parts operate across the identical temperature range of -40°C to 85°C. This specification applies to the R1180N331C-TR-YE, R1180N331B-TR-FE, and R1180N331C-TR-FE without variation.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All three parts use the SOT-23-5 package (SC-74A, SOT-753) with identical pin configuration and footprint. They are mechanically and electrically interchangeable on the same printed circuit board layout without modification to the PCB design or assembly process.
