Part Overview

The R1160N301A-TR-FE is a linear voltage regulator IC manufactured by Nisshinbo Micro Devices Inc., designed to provide a fixed 3V positive output at 200mA in a surface-mount SOT-23-5 package. This device is classified as a Power Management IC (PMIC) and is currently in active product status with 757 units in stock.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R1160N301A-TR-FE is determined by the following critical parameters:

Mandatory Matching Parameters:

• Output voltage: 3V fixed
• Output current capability: 200mA minimum
• Input voltage maximum: 6V
• Package type: SOT-23-5 (SC-74A, SOT-753)
• Output configuration: Positive
• Output type: Fixed
• Number of regulators: 1
• Control features: Enable function
• Protection features: Over Current protection
• Operating temperature range: -40°C to 85°C

Allowable Variation Parameters:

• Voltage dropout: May vary within acceptable limits for the application
• Quiescent current: Lower values are acceptable
• PSRR: Equal or higher values are acceptable
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) are both acceptable
• RoHS compliance: Both RoHS and ROHS3 compliant parts are acceptable
• Moisture Sensitivity Level: MSL 1 or MSL 3 are both acceptable

All substitute parts listed below meet the mandatory matching parameters and are therefore functionally equivalent for direct replacement in applications designed for the R1160N301A-TR-FE.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

The AP2121AK-3.0TRG1 (Diodes Incorporated), TCR2EF30,LM(CT (Toshiba Semiconductor), and XC6217A302MR-G (Torex Semiconductor) are all active products suitable for direct replacement of the R1160N301A-TR-FE. These three parts maintain full functional equivalence with the original specification.

The AP2121AK-3.0TRG1 offers ROHS3 compliance and higher inventory availability (16829 units) compared to the original part. The voltage dropout specification is 0.5V at 200mA, which is higher than the original 0.25V but remains within acceptable operational limits for most applications.

The TCR2EF30,LM(CT provides superior performance characteristics, including lower voltage dropout (0.2V @ 150mA) and higher PSRR (73dB at 1kHz). This part is available in the highest quantity (300100 units) and maintains RoHS compliance with MSL 1 rating. The input voltage maximum is specified at 5.5V, which is 0.5V lower than other alternatives.

The XC6217A302MR-G demonstrates the lowest quiescent current (8µA) and lowest voltage dropout (0.14V @ 100mA) among all listed substitutes. This part is ROHS3 compliant and maintains MSL 1 rating. The package designation is SOT-25-5, which is mechanically compatible with SOT-23-5 footprints in most PCB designs.

Secondary Substitute (Obsolete Product Status):

The SP6260EEK-L/TR (MaxLinear, Inc.) is classified as obsolete and should be avoided for new designs or long-term production requirements. While this part meets all functional parameters and offers high inventory availability (35400 units), its obsolete status presents supply chain risk for future procurement.

Compliance Considerations:

All active substitute parts maintain compliance with RoHS or ROHS3 standards. The original R1160N301A-TR-FE and TCR2EF30,LM(CT both carry RoHS compliance with MSL 1 rating, indicating unlimited shelf life under controlled storage conditions. The AP2121AK-3.0TRG1 and XC6217A302MR-G carry ROHS3 compliance with MSL 3 and MSL 1 ratings respectively, requiring attention to moisture exposure during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the AP2121AK-3.0TRG1 be used as a direct replacement for the R1160N301A-TR-FE?

A: Yes. The AP2121AK-3.0TRG1 meets all mandatory electrical parameters: 3V fixed output, 200mA output current, 6V maximum input voltage, SOT-23-5 package, enable control, and over-current protection. The voltage dropout specification of 0.5V at 200mA is higher than the original 0.25V but remains functionally equivalent for applications designed within these tolerances.

Q: What is the difference between the TCR2EF30,LM(CT and other substitutes?

A: The TCR2EF30,LM(CT offers superior electrical performance with lower voltage dropout (0.2V @ 150mA) and higher PSRR (73dB). However, the maximum input voltage is specified at 5.5V compared to 6V for other parts. This part is suitable for applications where input voltage does not exceed 5.5V and where lower dropout voltage is beneficial.

Q: Why is the SP6260EEK-L/TR listed if it is obsolete?

A: The SP6260EEK-L/TR is included for reference purposes only, as it appears in the cross-reference documentation for the R1160N301A-TR-FE. This part should not be selected for new designs or production quantities due to its obsolete status and associated supply chain risk.

Q: Are there package compatibility issues between SOT-23-5 and SOT-25-5?

A: The XC6217A302MR-G uses a SOT-25-5 package while the original R1160N301A-TR-FE uses SOT-23-5. Both packages are mechanically compatible with standard SOT-23-5 PCB footprints, as the SOT-25-5 pinout is a superset of SOT-23-5. However, PCB layout verification is required to confirm footprint compatibility in specific designs.

Q: Which substitute offers the best performance for low-power applications?

A: The XC6217A302MR-G provides the lowest quiescent current at 8µA, making it optimal for battery-powered or low-power standby applications. This part also offers the lowest voltage dropout at 0.14V @ 100mA, reducing power dissipation in the regulator.

Q: What are the moisture sensitivity considerations for these substitutes?

A: The R1160N301A-TR-FE, TCR2EF30,LM(CT, and XC6217A302MR-G all carry MSL 1 rating, indicating unlimited shelf life under controlled storage. The AP2121AK-3.0TRG1 carries MSL 3 rating, requiring storage at controlled humidity levels and limiting shelf life to 168 hours after moisture exposure. Proper handling and storage procedures must be followed for MSL 3 components.

Q: Can these parts be used interchangeably in production?

A: Yes, all active substitute parts are functionally equivalent and can be used interchangeably in applications designed for the R1160N301A-TR-FE. However, design verification is recommended when switching between parts with different voltage dropout specifications or input voltage maximums, particularly for applications operating near the specified limits.

Q: Which substitute has the best availability?

A: The TCR2EF30,LM(CT offers the highest inventory availability at 300100 units, followed by SP6260EEK-L/TR at 35400 units and AP2121AK-3.0TRG1 at 16829 units. For long-term production requirements, the TCR2EF30,LM(CT provides the most reliable supply chain position.
