Substitute Categories:

Category 1: Direct Electrical Equivalents (AP7361C-12E-13) Identical electrical specifications including 0.7V maximum dropout voltage and 80 µA quiescent current. Differs only in packaging designation (SOT-223-3 vs. SOT-223R) and moisture sensitivity level (MSL 1 vs. MSL 1). Functionally interchangeable in all applications.

Category 2: Functional Equivalents with Performance Trade-offs (AP2114H-1.2TRG1, AP2114HA-1.2TRG1) Both AP2114 variants maintain identical output voltage, current, and input voltage specifications. Key differences include increased dropout voltage (1.3V @ 1A vs. 0.7V @ 1A) and reduced quiescent current (75 µA vs. 80 µA). PSRR specification differs (68dB at 100Hz-1kHz vs. 75dB-55dB at 1kHz-10kHz). Moisture sensitivity level is MSL 3 (168 hours). These parts are suitable for applications where higher dropout voltage is acceptable and lower quiescent current is beneficial.

Engineering Selection Recommendations

AP7361C-12E-13 is the primary substitute for AP7361C-12ER-13. Both parts share identical electrical specifications and differ only in packaging designation and moisture sensitivity level. Selection between these two is based on packaging requirements and storage environment conditions. Both maintain ROHS3 compliance and active product status.

AP2114H-1.2TRG1 and AP2114HA-1.2TRG1 are functional equivalents suitable for applications where the increased dropout voltage of 1.3V @ 1A is acceptable. These parts offer lower quiescent current (75 µA) and higher inventory availability. MSL 3 rating requires adherence to moisture control procedures during storage and handling. Both variants maintain ROHS3 compliance and active production status. Selection between AP2114H-1.2TRG1 and AP2114HA-1.2TRG1 is based on inventory availability and procurement lead time requirements.

Frequently Asked Questions (FAQ)

Q: Can AP7361C-12E-13 be used as a direct replacement for AP7361C-12ER-13?

A: Yes. Both parts have identical electrical specifications including 0.7V maximum dropout voltage, 80 µA quiescent current, and 1A output current at 1.2V fixed output. The primary difference is packaging designation (SOT-223-3 vs. SOT-223R) and moisture sensitivity level (both MSL 1). Verify PCB footprint compatibility before substitution.

Q: What are the limitations of using AP2114H-1.2TRG1 or AP2114HA-1.2TRG1 as substitutes?

A: The AP2114 variants have a maximum dropout voltage of 1.3V @ 1A, compared to 0.7V @ 1A for the AP7361C series. This increased dropout voltage may affect circuit performance in applications with tight input-to-output voltage margins. Quiescent current is lower at 75 µA. PSRR specification differs (68dB at 100Hz-1kHz vs. 75dB-55dB at 1kHz-10kHz). Moisture sensitivity level is MSL 3, requiring controlled storage conditions.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. AP7361C-12E-13, AP2114H-1.2TRG1, and AP2114HA-1.2TRG1 are all ROHS3 compliant and suitable for applications requiring environmental compliance certification.

Q: What is the difference between AP2114H-1.2TRG1 and AP2114HA-1.2TRG1?

A: Both parts have identical electrical specifications and packaging. The difference is in inventory availability (28,607 units for AP2114H-1.2TRG1 vs. 65,052 units for AP2114HA-1.2TRG1). Selection is based on procurement requirements and lead time considerations.

Q: Do all substitute parts use the same SOT-223 package?

A: All substitute parts use SOT-223 package family variants (SOT-223R or SOT-223-3). Verify specific footprint requirements with PCB design documentation, as minor pin configuration differences may exist between SOT-223R and SOT-223-3 designations.

Q: What moisture sensitivity precautions apply to AP2114 variants?

A: AP2114H-1.2TRG1 and AP2114HA-1.2TRG1 have MSL 3 rating (168 hours). These parts require moisture control during storage and handling. Baking procedures may be necessary if moisture absorption limits are exceeded. AP7361C series parts have MSL 1 (unlimited) and do not require moisture control procedures.
