Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT9169-13GV are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Output voltage matching: 1.3V fixed output
• Package compatibility: SOT-23-3 form factor
• Output current capability: Equal to or greater than 100mA
• Input voltage range: Maximum 6V or higher
• Operating temperature range: -40°C to 85°C or wider
• Regulatory compliance: ROHS3 compliant
• Protection features: Over Current protection present

The AP2120N-1.3TRG1 meets all substitution criteria with enhanced specifications in output current (150mA) and PSRR performance, while maintaining identical voltage output, package type, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RT9169-13GV and AP2120N-1.3TRG1 are Active status products with ROHS3 compliance and REACH Unaffected designation. Selection between these parts should be based on the following criteria:

• RT9169-13GV: Select when quiescent current minimization is critical (7 µA vs. 50 µA) or when PSRR performance at 30dB is acceptable for the application.
• AP2120N-1.3TRG1: Select when higher output current capability (150mA vs. 100mA) is required or when superior PSRR performance (65dB) is beneficial for noise-sensitive applications.

Both parts maintain identical output voltage, package form factor, and operating temperature range. The dropout voltage specification difference (0.6V @ 100mA vs. 0.8V @ 200mA) reflects measurement conditions at different current levels and does not prevent substitution within the 100mA operating range of the original design.

Frequently Asked Questions (FAQ)

Q: Can AP2120N-1.3TRG1 directly replace RT9169-13GV in existing designs?

A: Yes. Both parts share identical output voltage (1.3V), package type (SOT-23-3), operating temperature range (-40°C to 85°C), and protection features. The AP2120N-1.3TRG1 provides higher output current capability (150mA vs. 100mA), making it a direct substitute with enhanced performance margin.

Q: What are the key differences between these parts?

A: The primary differences are output current rating (100mA vs. 150mA), quiescent current (7 µA vs. 50 µA), and PSRR performance (30dB vs. 65dB at 1kHz). The AP2120N-1.3TRG1 offers higher current capacity and better noise rejection, while the RT9169-13GV provides lower standby current consumption.

Q: Are both parts available in the same package?

A: Yes. Both the RT9169-13GV and AP2120N-1.3TRG1 use the SOT-23-3 package (TO-236-3, SC-59), ensuring identical PCB footprint and mounting compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH Unaffected, and classified under ECCN EAR99 with identical HTSUS code (8542.39.0001).

Q: What is the maximum input voltage for both regulators?

A: Both parts accept a maximum input voltage of 6V, ensuring compatibility in applications with identical power supply constraints.
