R1114D151A-TR-FE Equivalent & Substitute Parts

Part Overview

The R1114D151A-TR-FE is a linear voltage regulator IC manufactured by Nisshinbo Micro Devices Inc., classified as a Power Management (PMIC) component. This device delivers a fixed positive 1.5V output at 150mA with integrated enable control and over-current protection. The part is actively produced and RoHS compliant, designed for surface mount applications in SON1612-6 packaging.

Substitute parts are identified when component availability is limited, supply chain disruptions occur, or inventory requirements necessitate alternative sourcing from the same manufacturer's product line while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the R1114D151A-TR-FE are identified within the R1114x series from Nisshinbo Micro Devices Inc. based on strict parametric equivalence. All substitute parts maintain identical electrical specifications across the following critical parameters:

• Fixed output voltage of 1.5V
• Maximum output current of 150mA
• Maximum input voltage of 6V
• Dropout voltage of 0.7V at 150mA
• Quiescent current of 95 µA
• PSRR performance of 70dB ~ 60dB (1kHz ~ 10kHz)
• Enable control feature and over-current protection
• Operating temperature range of -40°C ~ 85°C
• SON1612-6 package configuration
• Surface mount mounting type
• RoHS compliance and MSL 1 rating

Substitution is valid only when all parameters listed above are matched. The suffix designations (A, B, D) within the part number represent internal manufacturing or qualification variants that do not alter the functional or electrical characteristics of the device.

Parameter Comparison

Engineering Selection Recommendations

All three parts—R1114D151A-TR-FE, R1114D151B-TR-FE, and R1114D151D-TR-FE—are active products from Nisshinbo Micro Devices Inc. with identical electrical and mechanical specifications. Each part carries RoHS compliance certification and MSL 1 rating, confirming suitability for standard manufacturing and storage conditions without moisture sensitivity constraints.

Selection between these parts is determined by availability and supply chain requirements rather than functional differences. All parts are qualified for direct substitution in applications requiring a 1.5V fixed positive linear regulator with 150mA output capacity, enable control, and over-current protection in SON1612-6 surface mount packaging.

Frequently Asked Questions (FAQ)

Q: Can R1114D151B-TR-FE replace R1114D151A-TR-FE in an existing design?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications, including output voltage, current rating, dropout voltage, quiescent current, PSRR, control features, protection features, operating temperature range, and package configuration. Direct substitution is valid without design modification.

Q: Are there differences in the suffix designations (A, B, D) within the part number?

A: The suffix designations represent internal manufacturing or qualification variants within the R1114x series. These designations do not alter functional or electrical characteristics. All variants with the same core specification (R1114D151) deliver identical performance.

Q: What is the significance of the SON1612-6 package designation?

A: SON1612-6 is the supplier device package specification for this linear regulator. It corresponds to SOT-563 and SOT-666 case styles and defines the physical footprint, pin configuration, and thermal characteristics. All substitute parts use the same package, ensuring PCB compatibility without layout changes.

Q: Are all three parts RoHS compliant?

A: Yes. R1114D151A-TR-FE, R1114D151B-TR-FE, and R1114D151D-TR-FE are all RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, confirming compliance with environmental regulations and standard handling requirements.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All three parts operate across the identical temperature range of -40°C ~ 85°C. Selection between them is not constrained by thermal performance differences.

Q: What is the significance of Tape & Reel (TR) packaging?

A: Tape & Reel packaging indicates the parts are supplied in continuous tape format suitable for automated pick-and-place assembly. All substitute parts use this packaging format, ensuring compatibility with standard manufacturing processes.
