RT9169-13GVL Equivalent & Substitute Parts

Part Overview

The RT9169-13GVL is a linear voltage regulator IC manufactured by Richtek USA Inc., designed to deliver a fixed 1.3V output at up to 100mA. This positive fixed output regulator operates across an input voltage range up to 6V with a maximum dropout voltage of 0.6V at 100mA. The device is housed in a SOT-23-3 surface mount package and is actively produced, with ROHS3 compliance and Moisture Sensitivity Level 3 rating.

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 AP2120N-1.3TRG1 qualifies as a substitute for the RT9169-13GVL based on the following critical parameters:

• Fixed output voltage of 1.3V matches the primary requirement
• Input voltage maximum of 6V is identical
• Operating temperature range of -40°C ~ 85°C is identical
• SOT-23-3 package type provides mechanical and thermal compatibility
• Over Current protection feature is present in both devices
• ROHS3 compliance and MSL 3 rating are equivalent
• Output current capability of 150mA exceeds the 100mA requirement, providing design margin

Parameter Comparison

Engineering Selection Recommendations

The AP2120N-1.3TRG1 is suitable as a direct substitute for the RT9169-13GVL in applications where the following conditions are met:

• Circuit design accommodates the higher quiescent current of 50 µA versus 7 µA
• Application does not require the lower dropout voltage specification of 0.6V at 100mA
• PCB layout and thermal management are compatible with SOT-23-3 package dimensions
• Both devices maintain ROHS3 compliance and equivalent moisture sensitivity ratings
• Supply chain availability and cost considerations favor the substitute part

The AP2120N-1.3TRG1 provides superior PSRR performance at 65dB compared to 30dB, which may benefit noise-sensitive applications. The higher output current rating of 150mA provides additional design margin for the 100mA requirement.

Frequently Asked Questions (FAQ)

Q: Can the AP2120N-1.3TRG1 be used as a direct pin-for-pin replacement?

A: Yes. Both devices use the SOT-23-3 package with identical pinout configuration, enabling direct PCB substitution without layout modifications.

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

A: The AP2120N-1.3TRG1 has a higher output current rating (150mA vs 100mA), higher quiescent current (50 µA vs 7 µA), and superior PSRR performance (65dB vs 30dB). The RT9169-13GVL offers lower dropout voltage at the specified 100mA output current.

Q: Are there any thermal or package considerations?

A: Both devices are housed in SOT-23-3 surface mount packages with identical mechanical dimensions. Thermal performance depends on PCB copper area and layout design, which are independent of the device selection.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RT9169-13GVL and AP2120N-1.3TRG1 are ROHS3 compliant with MSL 3 ratings and identical operating temperature ranges of -40°C ~ 85°C.

Q: What should be verified before substitution?

A: Confirm that the application circuit can tolerate the higher quiescent current draw of the substitute part and that the higher dropout voltage specification does not impact system performance at the intended operating current levels.
