RT9013-30GY Equivalent & Substitute Parts

Part Overview

The RT9013-30GY is a linear voltage regulator IC from Richtek USA Inc. designed for positive fixed output applications. This Surface Mount device delivers 500mA output current with a fixed 3V output and is classified as Active product status. The regulator features integrated over-current and over-temperature protection, making it suitable for low-power supply applications requiring stable 3V regulation from input sources up to 5.5V.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this product category.

Key Parameters

Substitute Part Grouping Explanation

The XC6218P302NR-G from Torex Semiconductor Ltd qualifies as a substitute based on the following alignment of critical parameters:

Matching Parameters:

• Output Voltage (Fixed): 3V
• Output Configuration: Positive Fixed
• Input Voltage (Max): 6V (exceeds RT9013-30GY requirement of 5.5V)
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: SC-82
• RoHS Status: ROHS3 Compliant
• Protection Features: Over Current protection included

Parameter Variance:

• Output Current: 200mA (lower than RT9013-30GY 500mA)
• Voltage Dropout: 0.32V @ 100mA (lower than RT9013-30GY 0.4V @ 500mA)
• Quiescent Current: 5 µA (lower than RT9013-30GY 50 µA)

The XC6218P302NR-G is suitable for applications where the required output current does not exceed 200mA, maintaining the same fixed 3V output voltage and operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

RT9013-30GY Selection Criteria:

• Applications requiring 500mA output current capacity
• Systems with input voltage limited to 5.5V maximum
• Designs where over-temperature protection is a primary requirement

XC6218P302NR-G Selection Criteria:

• Applications with output current requirements not exceeding 200mA
• Systems tolerating higher input voltage up to 6V
• Designs benefiting from lower quiescent current (5 µA vs. 50 µA)
• Applications where MSL-1 moisture sensitivity is advantageous

Both parts maintain Active product status and ROHS3 compliance. Selection between these regulators depends on the specific output current requirement of the application circuit.

Frequently Asked Questions (FAQ)

Q: Can XC6218P302NR-G replace RT9013-30GY in all applications?

A: No. The XC6218P302NR-G has a maximum output current of 200mA, while the RT9013-30GY supports 500mA. Substitution is valid only when the application circuit draws 200mA or less from the 3V output.

Q: What is the significance of the different package designations (SC-82 vs. SSOT-24)?

A: Both parts use SC-82 as the Package / Case specification. The XC6218P302NR-G Supplier Device Package is listed as SSOT-24, which is the manufacturer's internal designation. The SC-82 specification confirms mechanical and electrical compatibility for PCB mounting.

Q: How do the protection features differ between these regulators?

A: RT9013-30GY includes Over Current and Over Temperature protection. XC6218P302NR-G includes Over Current and Short Circuit protection. Both provide over-current limiting; the difference lies in secondary protection mechanisms.

Q: Is the lower quiescent current of XC6218P302NR-G significant for battery-powered applications?

A: Yes. The XC6218P302NR-G draws 5 µA quiescent current compared to 50 µA for RT9013-30GY. In battery-powered or low-power standby applications, this 10x reduction in quiescent current can extend battery life.

Q: Are there input voltage compatibility concerns?

A: The XC6218P302NR-G accepts input voltage up to 6V, while RT9013-30GY is rated to 5.5V maximum. If your input source exceeds 5.5V, the XC6218P302NR-G provides additional margin. Both regulators maintain the same 3V fixed output.
