Substitute Part Grouping Explanation

Substitute parts are grouped based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Fixed output voltage of 2.2V
Output current capability of 150mA
Maximum input voltage of 6.0V to 6.5V
Dropout voltage performance at specified current levels
SOT-23-5 package configuration
Enable control feature and over-current protection
Operating temperature range of -40°C ~ 85°C
RoHS3 compliance and MSL Level 1 rating

Parts within this grouping maintain functional equivalence for direct replacement in existing designs. Variations in quiescent current, PSRR, and supply current do not affect substitution eligibility when all primary parameters align.

Engineering Selection Recommendations

For applications currently using S-T111B22MC-OGHTFG, the following selection criteria apply:

ABLIC Inc. Series (Preferred for Direct Replacement)

S-T111B22MC-OGHTFU, S-1112B22MC-L6HTFU, S-1122B22MC-L8HTFU, and S-1167B22-M5T1U are all active products from ABLIC Inc. with identical electrical specifications to the original part. These parts maintain the same output voltage, current rating, dropout voltage performance, and package configuration. All are RoHS3 compliant with MSL Level 1 rating. S-1167B22-M5T1U offers improved quiescent current performance (900 nA versus 1 µA) and reduced supply current (16 µA versus 90 µA), providing potential power consumption benefits in battery-powered applications.

Cross-Manufacturer Alternative

XC6504A221MR-G from Torex Semiconductor Ltd provides functional equivalence with identical output voltage and current ratings. This part is active and RoHS3 compliant. The maximum input voltage is reduced to 6.0V (versus 6.5V for ABLIC parts) and dropout voltage is higher at 1.05V @ 150mA (versus 0.35V @ 100mA). The package designation differs (SOT-25 versus SOT-23-5), requiring PCB layout verification. Selection of this part is appropriate only when input voltage does not exceed 6.0V and higher dropout voltage is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can S-T111B22MC-OGHTFU be used as a direct replacement for S-T111B22MC-OGHTFG?

A: Yes. Both parts share identical electrical specifications including output voltage, current rating, dropout voltage, and package type. The primary difference is product status: S-T111B22MC-OGHTFU is active while S-T111B22MC-OGHTFG is not for new designs. Mechanical and electrical compatibility is complete.

Q: What is the difference between ABLIC parts and the Torex XC6504A221MR-G?

A: The XC6504A221MR-G maintains the same 2.2V output and 150mA current rating. Key differences are: maximum input voltage is 6.0V instead of 6.5V, dropout voltage is 1.05V @ 150mA instead of 0.35V @ 100mA, and the package is SOT-25 instead of SOT-23-5. Use this part only when input voltage remains below 6.0V and higher dropout voltage is acceptable.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parts listed are RoHS3 compliant with MSL Level 1 (unlimited moisture sensitivity level), matching the compliance profile of the original S-T111B22MC-OGHTFG.

Q: Does package type affect substitution?

A: Package type must match for direct PCB replacement. ABLIC parts use SOT-23-5 (SC-74A) packaging identical to the original. The Torex XC6504A221MR-G uses SOT-25 packaging, which requires PCB layout modification and is not a direct drop-in replacement.

Q: Which substitute part offers the best power efficiency?

A: S-1167B22-M5T1U provides the lowest quiescent current at 900 nA and the lowest supply current at 16 µA, compared to 1 µA and 90 µA respectively for other ABLIC parts. This makes S-1167B22-M5T1U suitable for power-sensitive applications.

Q: Can I use these parts interchangeably in production?

A: ABLIC parts S-T111B22MC-OGHTFU, S-1112B22MC-L6HTFU, S-1122B22MC-L8HTFU, and S-1167B22-M5T1U are fully interchangeable from an electrical and mechanical standpoint. The Torex XC6504A221MR-G requires input voltage and dropout voltage verification before use.
