R1114D281D-TR-FE Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The R1114D281D-TR-FE is an active linear voltage regulator IC manufactured by Nisshinbo Micro Devices Inc., classified as a Power Management (PMIC) component. This device functions as a positive fixed output voltage regulator delivering 2.8V at 150mA output current in a surface mount SON1612-6 package. The part is RoHS Compliant and currently in active production status with 831 pieces available in inventory.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across critical parameters including output voltage, output current capacity, package type, and operating temperature range. Alternative models may be required due to inventory availability, supply chain considerations, or specific application requirements for quiescent current performance.

Substitute Part Grouping Explanation

Substitute parts for the R1114D281D-TR-FE are identified based on strict parametric equivalence across the following critical criteria:

Electrical Equivalence Requirements:

• Fixed output voltage of 2.8V
• Output current capacity of 150mA
• Maximum input voltage of 6V
• Operating temperature range of -40°C to 85°C
• Enable control feature
• Over current protection feature

Mechanical Equivalence Requirements:

• SON1612-6 package (SOT-563, SOT-666 equivalent)
• Surface mount configuration
• Tape & Reel (TR) packaging format

Compliance Requirements:

• RoHS Compliant or ROHS3 Compliant status
• Active product status

The R1180D281B-TR-FE meets all electrical and mechanical equivalence criteria. Variations in voltage dropout specification (0.4V versus 0.35V) and quiescent current (1.5µA versus 95µA) remain within acceptable tolerance for linear regulator substitution in applications where the R1114D281D-TR-FE specifications are required.

Parameter Comparison

Engineering Selection Recommendations

R1114D281D-TR-FE Selection Criteria:

• Primary choice when RoHS Compliant (non-ROHS3) certification is required
• Applications requiring quiescent current specification of 95µA
• Designs where voltage dropout of 0.35V @ 150mA is a critical specification
• Current inventory availability of 831 pieces supports immediate procurement

R1180D281B-TR-FE Selection Criteria:

• Primary choice when ROHS3 Compliant certification is required
• Applications where lower quiescent current (1.5µA) provides power efficiency benefits
• Designs tolerant of 0.4V voltage dropout @ 150mA specification
• Higher inventory availability of 3533 pieces supports extended supply chain requirements
• REACH Unaffected status provides additional regulatory compliance documentation

Both parts maintain identical electrical performance for output voltage (2.8V), output current (150mA), input voltage maximum (6V), operating temperature range (-40°C to 85°C), and package configuration (SON1612-6 surface mount). Both parts are active products from the same manufacturer with equivalent control and protection features.

Frequently Asked Questions (FAQ)

Q: Can R1180D281B-TR-FE directly replace R1114D281D-TR-FE in existing designs?

A: Yes. Both parts deliver identical 2.8V fixed output voltage at 150mA output current in SON1612-6 surface mount packages. Electrical performance is equivalent across output voltage, output current, input voltage maximum, operating temperature range, control features, and protection features. The voltage dropout difference (0.4V versus 0.35V) and quiescent current difference (1.5µA versus 95µA) are within acceptable tolerance for linear regulator applications.

Q: What is the significance of the voltage dropout specification difference?

A: Voltage dropout is the minimum voltage differential required between input and output for proper regulator operation. The R1114D281D-TR-FE specifies 0.35V dropout while the R1180D281B-TR-FE specifies 0.4V dropout. Both values are typical for linear regulators in this class. Applications with input voltages significantly above the 2.8V output requirement accommodate either specification without performance impact.

Q: Why does the R1180D281B-TR-FE have significantly lower quiescent current?

A: Quiescent current represents the internal current consumption of the regulator when no load is applied. The R1180D281B-TR-FE operates at 1.5µA compared to 95µA for the R1114D281D-TR-FE. This difference reflects different internal circuit design approaches. Applications requiring extended battery life or ultra-low standby power consumption benefit from the R1180D281B-TR-FE specification.

Q: Are the package dimensions identical between these parts?

A: Yes. Both parts use SON1612-6 package designation, also referenced as SOT-563 and SOT-666 equivalents. Package footprint, pin configuration, and surface mount assembly requirements are identical.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant status?

A: RoHS Compliant indicates compliance with the original Restriction of Hazardous Substances directive. ROHS3 Compliant indicates compliance with the updated RoHS 3 directive (2011/65/EU as amended by 2015/863/EU), which includes additional restricted substances. ROHS3 Compliant parts meet all original RoHS requirements plus additional restrictions.

Q: Can these parts be used interchangeably in high-volume production?

A: Yes, provided the application design accommodates the specified voltage dropout and quiescent current parameters of the selected part. Both parts are active products with stable supply availability. Design validation should confirm that the specific electrical characteristics of the selected part meet application requirements.

Q: What is the significance of Moisture Sensitivity Level 1 (Unlimited)?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both parts carry this classification, eliminating moisture-related storage or assembly constraints.
