Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R1114Q151D-TR-FE is determined by the following critical parameters:

• Output Voltage: Fixed 1.5V output
• Output Current: 150mA maximum
• Input Voltage Range: Maximum 6V
• Package Type: SC-82A (SOT-343) surface mount
• Output Configuration: Positive fixed regulator
• Control Features: Enable function present
• Protection: Over-current protection included
• Compliance: RoHS compliant status

The R1180Q151B-TR-FE meets all substitution criteria within these parameters. Both devices are manufactured by Nisshinbo Micro Devices Inc., operate across the same temperature range (-40°C to 85°C), and are packaged identically in SC-82A (SOT-343) format with tape and reel delivery.

Parameter Comparison

Engineering Selection Recommendations

Both the R1114Q151D-TR-FE and R1180Q151B-TR-FE are active products with RoHS compliance and MSL Level 1 rating, indicating unlimited shelf life under standard storage conditions. Selection between these devices is based on application-specific requirements within the provided parameter set.

The R1114Q151D-TR-FE exhibits lower quiescent current (95 µA) and lower dropout voltage (0.7V @ 150mA), making it suitable for applications requiring minimal standby power consumption and operation closer to the input voltage limit.

The R1180Q151B-TR-FE demonstrates significantly lower quiescent current (1.5 µA), providing superior efficiency in low-power standby scenarios, though with slightly higher dropout voltage (0.9V @ 150mA).

Both devices maintain identical output voltage (1.5V), output current (150mA), input voltage maximum (6V), operating temperature range (-40°C to 85°C), and package configuration (SC-82A, SOT-343). Both include enable control and over-current protection.

Frequently Asked Questions (FAQ)

Q: Can the R1180Q151B-TR-FE directly replace the R1114Q151D-TR-FE in existing designs?

A: Yes. Both devices share identical output voltage (1.5V), output current (150mA), input voltage specifications (6V maximum), package type (SC-82A, SOT-343), and control/protection features. Pin-to-pin compatibility is maintained.

Q: What is the primary difference between these two regulators?

A: The R1180Q151B-TR-FE has significantly lower quiescent current (1.5 µA versus 95 µA) but slightly higher dropout voltage (0.9V versus 0.7V at 150mA). The choice depends on whether minimizing standby power or maximizing headroom above the output voltage is the priority.

Q: Are both parts available in the same packaging format?

A: Yes. Both the R1114Q151D-TR-FE and R1180Q151B-TR-FE are supplied in SC-82A (SOT-343) surface mount packages with tape and reel delivery (TR).

Q: Do both parts operate across the same temperature range?

A: Yes. Both devices operate from -40°C to 85°C, ensuring compatibility in equivalent thermal environments.

Q: Are there any compliance differences between these parts?

A: No. Both parts are RoHS compliant with MSL Level 1 rating and identical ECCN and HTSUS classifications.

Q: Which part should be selected for battery-powered applications?

A: The R1180Q151B-TR-FE is preferred for battery-powered applications due to its extremely low quiescent current (1.5 µA), which minimizes standby power drain.

Q: Which part should be selected for applications requiring maximum input voltage headroom?

A: The R1114Q151D-TR-FE is preferred when maximum headroom between input and output voltage is required, as it exhibits lower dropout voltage (0.7V versus 0.9V at 150mA).
