R1114N301A-TR-FE Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The R1114N301A-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 3V at 150mA output current in a surface mount SOT-23-5 package. The regulator includes enable control and over-current protection features, operating across the industrial temperature range of -40°C to 85°C.

Equivalent and substitute parts are identified when alternative manufacturers offer linear voltage regulators with matching electrical specifications and compatible package configurations. Substitute components maintain functional equivalence through identical or superior performance parameters while meeting the same application requirements.

Engineering Selection Recommendations

R1114N301A-TR-FE Selection: The R1114N301A-TR-FE remains the primary choice when the original Nisshinbo device is specified in design documentation or when the lower dropout voltage of 0.35V is a critical system requirement. This device is actively manufactured and maintains RoHS compliance. Current inventory of 790 pieces supports immediate procurement needs.

XC6504A301MR-G Selection: The XC6504A301MR-G from Torex Semiconductor Ltd functions as a direct substitute when supply constraints affect R1114N301A-TR-FE availability. This device meets all electrical and mechanical requirements with ROHS3 compliance certification. The substitute exhibits superior quiescent current performance (1.27µA versus 95µA), reducing standby power consumption in battery-powered applications. The higher dropout voltage of 0.67V requires verification that system input voltage headroom remains adequate. Significantly higher inventory availability (29,200 pieces) supports extended production runs and supply chain resilience.

Both devices are active products with unlimited moisture sensitivity ratings, suitable for standard surface mount assembly processes without special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the XC6504A301MR-G directly replace the R1114N301A-TR-FE without PCB modifications?

A: Yes. Both devices use compatible SOT-23-5 / SC-74A surface mount packages with identical pin configurations and footprints. No PCB layout changes are required for mechanical substitution. Electrical functionality remains equivalent across all specified parameters.

Q: What is the significance of the different dropout voltage specifications?

A: The R1114N301A-TR-FE specifies 0.35V dropout at 150mA, while the XC6504A301MR-G specifies 0.67V dropout at the same current. Dropout voltage represents the minimum voltage differential between input and output required for proper regulation. Applications with limited input voltage headroom must confirm that the higher dropout voltage of the substitute does not cause output voltage collapse under maximum load conditions.

Q: Why does the XC6504A301MR-G have significantly lower quiescent current?

A: Quiescent current represents the device's internal power consumption when delivering no load current. The XC6504A301MR-G consumes 1.27µA compared to 95µA for the R1114N301A-TR-FE. This difference reflects different internal circuit design approaches between manufacturers. The lower quiescent current of the substitute reduces standby power consumption in applications where the regulator operates continuously but delivers minimal load current.

Q: Are both devices RoHS compliant?

A: Yes. The R1114N301A-TR-FE carries RoHS Compliant certification. The XC6504A301MR-G carries ROHS3 Compliant certification. Both certifications confirm the absence of restricted substances (lead, cadmium, mercury, hexavalent chromium, PBBs, and PBDEs) in the finished component.

Q: What packaging formats are available for these devices?

A: Both devices are supplied in Tape & Reel (TR) format for automated surface mount assembly. The R1114N301A-TR-FE uses SOT-23-5 packaging designation, while the XC6504A301MR-G uses SOT-25-5 packaging designation. Both reference the same SC-74A physical package form factor with identical pin spacing and dimensions.

Q: Can these regulators be used in parallel to increase output current?

A: No. Linear voltage regulators are not designed for parallel operation. Each device must operate independently with its own load circuit. Attempting parallel connection creates current-sharing instability and potential device damage.

Q: What is the moisture sensitivity level, and does it affect handling?

A: Both devices carry Moisture Sensitivity Level (MSL) rating of 1 (Unlimited). This classification indicates the component requires no special moisture control during storage, handling, or assembly. Standard manufacturing and storage conditions are acceptable without desiccant packaging or controlled humidity environments.

Q: Are there PSRR (Power Supply Rejection Ratio) specifications for the substitute?

A: The R1114N301A-TR-FE specifies PSRR of 70dB to 60dB across the 1kHz to 10kHz frequency range. The XC6504A301MR-G does not provide PSRR specification in the available technical data. PSRR measures the regulator's ability to reject input voltage noise and ripple. Applications requiring specific noise rejection performance should retain the R1114N301A-TR-FE or obtain detailed PSRR data from Torex Semiconductor Ltd for the substitute device.
