Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the S-T111B19MC-OGETFG are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Output voltage: 1.9V fixed
• Output current: 150mA
• Input voltage maximum: 6.5V or higher
• Package type: SOT-23-5 compatible
• Output configuration: Positive fixed
• Control features: Enable function
• Protection: Over current protection

Substitution Logic:

Parts are grouped into two categories based on electrical performance characteristics:

Category A - Direct Electrical Equivalents (Identical Dropout Performance): S-T111B19MC-OGETFU, S-1112B19MC-L6ETFU, and S-1122B19MC-L8ETFU maintain the same 0.35V maximum dropout voltage at 100mA as the original part. These devices are functionally interchangeable with identical quiescent current (1 µA) and PSRR (80dB at 1kHz). All three are from ABLIC Inc. and carry Active product status.

Category B - Functional Equivalents (Enhanced Performance Characteristics): S-1167A19-M5T1U and S-1167B19-M5T1U offer improved quiescent current performance (900 nA versus 1 µA) and reduced supply current (16 µA versus 90 µA), though with a higher dropout voltage of 0.58V at 100mA. Both are Active status parts from ABLIC Inc. The S-1167B19-M5T1U is available in Cut Tape packaging.

Cross-Manufacturer Alternative: XC6504A191MR-G from Torex Semiconductor Ltd provides functional equivalence with identical output specifications but differs in input voltage maximum (6V versus 6.5V), higher dropout voltage (1.29V at 150mA), and different quiescent current (1.5 µA). This part uses SOT-25 packaging.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

S-T111B19MC-OGETFU, S-1112B19MC-L6ETFU, and S-1122B19MC-L8ETFU are the primary substitutes. All three maintain the 0.35V dropout voltage specification and identical quiescent current characteristics. S-T111B19MC-OGETFU is the closest variant within the same S-T111 series. S-1112B19MC-L6ETFU and S-1122B19MC-L8ETFU represent alternative series from ABLIC Inc. with Active product status, ensuring long-term availability and support.

For Low-Power Applications:

S-1167A19-M5T1U and S-1167B19-M5T1U are suitable when reduced quiescent current (900 nA) and supply current (16 µA) are design priorities. The trade-off is increased dropout voltage (0.58V at 100mA). Both parts carry Active status. S-1167B19-M5T1U is available in Cut Tape packaging for lower-volume requirements.

For Cross-Manufacturer Sourcing:

XC6504A191MR-G from Torex Semiconductor Ltd provides an alternative source with identical output specifications. This part operates with a maximum input voltage of 6V (versus 6.5V) and exhibits higher dropout voltage (1.29V at 150mA). Selection of this part requires confirmation that the 6V input maximum and 1.29V dropout voltage are acceptable for the target application.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and the required operating temperature range of -40°C to 85°C.

Frequently Asked Questions (FAQ)

Q: Can S-1167A19-M5T1U or S-1167B19-M5T1U be used as direct replacements for S-T111B19MC-OGETFG?

A: These parts are functionally compatible for applications where the increased dropout voltage (0.58V versus 0.35V) does not impact circuit performance. The S-1167 series offers superior quiescent current performance (900 nA versus 1 µA) and reduced supply current (16 µA versus 90 µA), making them suitable for battery-powered or low-power applications. Electrical simulation or bench testing is necessary to confirm compatibility in dropout-sensitive designs.

Q: What is the difference between S-1167A19-M5T1U and S-1167B19-M5T1U?

A: Both parts are electrically identical. The primary difference is packaging: S-1167A19-M5T1U is supplied in Tape & Reel (TR) format for high-volume production, while S-1167B19-M5T1U is supplied in Cut Tape (CT) format for lower-volume or prototype applications.

Q: Is XC6504A191MR-G from Torex Semiconductor Ltd a suitable substitute?

A: XC6504A191MR-G provides equivalent output voltage and current specifications. However, it differs in three critical parameters: maximum input voltage is 6V (versus 6.5V), dropout voltage is 1.29V at 150mA (versus 0.35V), and quiescent current is 1.5 µA. Selection requires confirmation that these specifications align with circuit requirements.

Q: Why is S-T111B19MC-OGETFG marked as Not For New Designs?

A: This designation indicates the part is in mature or end-of-life status. Active alternatives such as S-T111B19MC-OGETFU, S-1112B19MC-L6ETFU, and S-1122B19MC-L8ETFU are recommended for new designs to ensure long-term supply continuity and manufacturer support.

Q: Are all substitute parts available in SOT-23-5 packaging?

A: All ABLIC Inc. substitutes (S-T111B19MC-OGETFU, S-1112B19MC-L6ETFU, S-1122B19MC-L8ETFU, S-1167A19-M5T1U, and S-1167B19-M5T1U) use SOT-23-5 packaging. XC6504A191MR-G from Torex uses SOT-25 packaging, which has identical pin count and footprint compatibility but may require PCB layout verification.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (Unlimited). All parts are classified under ECCN EAR99 and HTSUS 8542.39.0001.
