R1180N331C-TR-FE Equivalent & Substitute Parts

Part Overview

The R1180N331C-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 3.3V output at 150mA in a surface-mount SOT-23-5 package. The part is actively produced and maintains ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when component availability becomes constrained, supply chain disruptions occur, or inventory requirements necessitate alternative sourcing from the same manufacturer's product line. Equivalent parts maintain identical electrical performance and mechanical compatibility within the R1180x series.

• Dropout voltage of 0.4V @ 150mA
• Quiescent current of 1.5 µA
• Over Current protection feature

Mechanical Equivalence Criteria:

• SOT-23-5 package configuration (SC-74A, SOT-753)
• Surface-mount technology
• Tape & Reel (TR) packaging format

Compliance Equivalence Criteria:

• ROHS3 compliance
• MSL 1 (Unlimited) moisture sensitivity rating
• Active product status

The R1180N331B-TR-FE qualifies as a parametric equivalent substitute, maintaining all specified electrical and mechanical parameters while remaining within the R1180x series family.

Parameter Comparison

Engineering Selection Recommendations

Both the R1180N331C-TR-FE and R1180N331B-TR-FE are active products manufactured by Nisshinbo Micro Devices Inc. with full ROHS3 compliance and identical electrical specifications. Selection between these parts is based on the following engineering considerations:

Primary Selection Criteria:

• Both parts maintain identical output voltage, current rating, and thermal performance
• Both parts are certified for the same operating temperature range (-40°C to 85°C)
• Both parts employ identical SOT-23-5 packaging and surface-mount technology
• Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard storage and handling conditions

Differentiation Factor: The R1180N331B-TR-FE includes an Enable control feature not specified in the R1180N331C-TR-FE. This additional functionality allows external control of the regulator output state. Selection of the B-variant is appropriate when circuit design requires output enable/disable capability. Selection of the C-variant is appropriate when control features are not required and simplified operation is preferred.

Compliance Basis: Both parts satisfy ROHS3 compliance requirements and REACH unaffected status, making either part suitable for applications subject to environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can the R1180N331B-TR-FE directly replace the R1180N331C-TR-FE in existing designs?

A: Yes. The R1180N331B-TR-FE maintains identical electrical output specifications (3.3V, 150mA), dropout voltage (0.4V @ 150mA), quiescent current (1.5 µA), and SOT-23-5 package configuration. Pin-to-pin compatibility is maintained. The additional Enable control feature in the B-variant does not prevent direct substitution; the enable pin can be tied to the appropriate logic level if not utilized in the circuit design.

Q: Are there differences in thermal performance between these parts?

A: No. Both parts operate across the identical temperature range (-40°C to 85°C) and maintain the same quiescent current specification of 1.5 µA, indicating equivalent thermal characteristics.

Q: What is the significance of the Enable control feature in the R1180N331B-TR-FE?

A: The Enable feature allows external logic to control the regulator output state. This is useful in power management applications requiring dynamic output switching. If the design does not require this functionality, the enable pin should be connected to the appropriate logic level (typically VCC or GND) per the device datasheet to ensure proper operation.

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

A: Yes. Both the R1180N331C-TR-FE and R1180N331B-TR-FE are supplied in Tape & Reel (TR) format with SOT-23-5 package configuration (SC-74A, SOT-753 designations). This ensures compatibility with automated assembly equipment and standard component handling procedures.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard storage and handling procedures apply to both parts without special desiccant or controlled humidity requirements.

Q: What is the basis for substitution between these two parts?

A: Substitution is based on parametric equivalence within the R1180x series. Both parts deliver identical fixed 3.3V output at 150mA with matching dropout voltage, quiescent current, operating temperature range, and package configuration. Both maintain active product status and full ROHS3 compliance.
