Engineering Selection Recommendations

ABLIC Inc. Active Equivalents (Recommended Primary Substitutes):

S-T111B32MC-OGRTFU, S-1112B32MC-L6RTFU, and S-1122B32MC-L8RTFU are active ABLIC Inc. products with identical electrical specifications to the S-T111B32MC-OGRTFG. These parts maintain the same output voltage, current rating, dropout voltage, and PSRR characteristics. Selection between these three depends on packaging preference: S-T111B32MC-OGRTFU is supplied in Tape & Reel (TR), while S-1112B32MC-L6RTFU and S-1122B32MC-L8RTFU are supplied in Cut Tape (CT). All three carry ROHS3 compliance and active product status, making them suitable for new designs.

ABLIC Inc. Enhanced Alternative:

S-1167B32-M5T1U offers improved performance characteristics with lower quiescent current (900 nA vs. 1 µA), reduced supply current (16 µA vs. 90 µA), and lower dropout voltage (0.23V vs. 0.26V). This part is active and ROHS3 compliant. The trade-off is a lower PSRR rating (65dB vs. 80dB). This part is suitable for applications prioritizing low power consumption.

Cross-Manufacturer Alternatives:

RP130N321D-TR-FE (Nisshinbo Micro Devices Inc.) and XC6504A321MR-G (Torex Semiconductor Ltd) meet all primary electrical and package requirements. RP130N321D-TR-FE exhibits higher dropout voltage (0.51V @ 150mA) and quiescent current (58 µA), while XC6504A321MR-G has a slightly lower maximum input voltage (6V vs. 6.5V), higher dropout voltage (0.67V @ 150mA), and different supplier device package designation (SOT-25). Both are active and RoHS compliant. These alternatives are suitable when ABLIC Inc. parts are unavailable.

Frequently Asked Questions (FAQ)

Q: Can S-T111B32MC-OGRTFU be used as a direct replacement for S-T111B32MC-OGRTFG?

A: Yes. Both parts are from ABLIC Inc., share identical electrical specifications (3.2V output, 150mA current, 0.26V dropout voltage, 80dB PSRR), and use the same SOT-23-5 package. The primary difference is product status: S-T111B32MC-OGRTFG is "Not For New Designs" while S-T111B32MC-OGRTFU is active. Packaging format differs (Tape & Reel vs. the original part's format), but electrical performance is equivalent.

Q: What is the difference between S-1112B32MC-L6RTFU and S-1122B32MC-L8RTFU?

A: Both parts are ABLIC Inc. products with identical electrical specifications and active status. The difference lies in the series designation (S-1112 vs. S-1122) and packaging format (both Cut Tape). Electrically, they are interchangeable for the S-T111B32MC-OGRTFG application. Selection depends on inventory availability and packaging preference.

Q: Should I use S-1167B32-M5T1U instead of the standard equivalents?

A: S-1167B32-M5T1U is suitable if your application benefits from lower quiescent current (900 nA vs. 1 µA) and reduced supply current (16 µA vs. 90 µA). However, it has a lower PSRR rating (65dB vs. 80dB). Use this part only if power consumption is a critical design parameter and the lower PSRR is acceptable for your application.

Q: Can I use RP130N321D-TR-FE or XC6504A321MR-G?

A: Both parts meet the primary electrical requirements (3.2V output, 150mA current, SOT-23-5 package, -40°C to 85°C operating range). However, both exhibit higher dropout voltages (0.51V and 0.67V respectively vs. 0.26V for the original part). Use these alternatives only when ABLIC Inc. parts are unavailable and your circuit design accommodates the higher dropout voltage. XC6504A321MR-G has a maximum input voltage of 6V instead of 6.5V, which may be a limiting factor in some applications.

Q: What is the significance of the packaging format (Tape & Reel vs. Cut Tape)?

A: Tape & Reel (TR) and Cut Tape (CT) are supply formats that affect handling and assembly processes. Electrically, parts are identical regardless of packaging format. TR format is typically used for automated assembly lines, while CT format is suitable for manual assembly or smaller production runs. Select based on your manufacturing process requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry either ROHS3 or RoHS compliance certification, matching the original part's ROHS3 compliance status. All parts are also MSL 1 (Unlimited moisture sensitivity level), indicating no special moisture handling requirements.
