Key Parameters

Substitute Part Grouping Explanation

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

• Fixed output voltage of 2.7V
• Output current capability of 150mA
• Maximum input voltage of 6.5V or greater
• SOT-23-5 package compatibility
• Operating temperature range of -40°C to 85°C
• Enable control feature and over current protection

Parts are classified into two categories: ABLIC Inc. series variants (S-1112, S-1122, S-1167, and S-T111 Cut Tape variant) with identical or superior electrical characteristics, and cross-manufacturer alternatives (Torex Semiconductor) meeting the same functional requirements.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the S-T111B27MC-OGMTFG, the following selection criteria apply based on product status and compliance:

Primary Substitutes (ABLIC Inc., Active Status):

S-1112B27MC-L6MTFU, S-1122B27MC-L8MTFU, and S-T111B27MC-OGMTFU are direct electrical equivalents with Active product status. These parts maintain identical electrical specifications including 0.29V maximum dropout voltage, 80dB PSRR at 1kHz, and 90µA maximum supply current. Selection between these three depends on packaging requirements: S-1112B27MC-L6MTFU and S-1122B27MC-L8MTFU are supplied in Tape & Reel format, while S-T111B27MC-OGMTFU is available in Cut Tape format.

S-1167B27-M5T1U is an Active ABLIC alternative with improved quiescent current performance (900nA versus 1µA) and reduced supply current (16µA versus 90µA). The dropout voltage specification is marginally higher at 0.3V, and PSRR is reduced to 70dB. This part is suitable for low-power applications where quiescent current minimization is prioritized.

Cross-Manufacturer Alternative:

XC6504A271MR-G from Torex Semiconductor Ltd meets the core functional requirements of 2.7V fixed output at 150mA with Active product status. The maximum input voltage is reduced to 6V, and the dropout voltage is significantly higher at 0.82V at 150mA. This part is suitable only for applications where the reduced input voltage range and higher dropout voltage are acceptable.

Frequently Asked Questions (FAQ)

Q: Can S-1112B27MC-L6MTFU directly replace S-T111B27MC-OGMTFG in existing designs?

A: Yes. Both parts share identical electrical specifications: 2.7V fixed output, 150mA output current, 0.29V maximum dropout voltage at 100mA, 80dB PSRR, and SOT-23-5 package. The primary difference is product status: S-1112B27MC-L6MTFU is Active while the original part is Not For New Designs. Packaging format differs (Tape & Reel versus Tape & Reel), so verify procurement requirements.

Q: What is the difference between S-1167B27-M5T1U and the other ABLIC substitutes?

A: S-1167B27-M5T1U offers superior low-power characteristics with 900nA quiescent current and 16µA maximum supply current, compared to 1µA and 90µA respectively in other variants. The dropout voltage is marginally higher at 0.3V, and PSRR is reduced to 70dB. Select this part for battery-powered or ultra-low-power applications where quiescent current is a critical design parameter.

Q: Is XC6504A271MR-G a suitable substitute?

A: XC6504A271MR-G meets the core functional requirements of 2.7V output at 150mA with Active product status. However, the maximum input voltage is limited to 6V (versus 6.5V), and the dropout voltage is significantly higher at 0.82V at 150mA. This part is suitable only for applications where these electrical differences are acceptable. Additionally, the package is SOT-25 rather than SOT-23-5, requiring PCB layout verification.

Q: What packaging formats are available for substitutes?

A: ABLIC substitutes are available in two formats: Tape & Reel (S-1112B27MC-L6MTFU, S-1122B27MC-L8MTFU, S-1167B27-M5T1U) and Cut Tape (S-T111B27MC-OGMTFU). Torex XC6504A271MR-G is supplied in Tape & Reel format. Verify packaging requirements with procurement specifications before selection.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitutes maintain ROHS3 compliance, Moisture Sensitivity Level 1 (Unlimited), and REACH Unaffected status, matching the original part's regulatory compliance profile.
