Parameter Comparison

Engineering Selection Recommendations

S-1112B23MC-L6ITFU (ABLIC Inc.): This part is a parametric equivalent with identical electrical specifications to the S-T111B23MC-OGITFU. The primary difference is packaging format (Cut Tape versus Tape & Reel). Both parts maintain ROHS3 compliance and active product status. Selection is appropriate when Cut Tape packaging meets assembly requirements.

XC6215B232MR-G (Torex Semiconductor Ltd): This substitute maintains the 2.3V output voltage and 150mA current rating with identical operating temperature range. The input voltage maximum is reduced to 6.0V and dropout voltage increases to 0.65V at 100mA. Quiescent current is 1.5 µA. This part is suitable for applications where the reduced input voltage specification and increased dropout voltage are acceptable. ROHS3 compliance and active status are maintained.

XC6504A231MR-G (Torex Semiconductor Ltd): This substitute provides the same 2.3V output and 150mA capability with -40°C to 85°C operating range. Input voltage maximum is 6.0V and dropout voltage is 1.05V at 150mA. Quiescent current is 1.5 µA. Selection is appropriate only when the higher dropout voltage specification does not compromise circuit performance. ROHS3 compliance and active product status are confirmed.

All substitute parts carry ROHS3 compliance and active production status, ensuring long-term availability and regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can XC6215B232MR-G or XC6504A231MR-G be used as direct replacements for S-T111B23MC-OGITFU?

A: Both Torex parts are parametric equivalents for the core function (2.3V, 150mA linear regulation). However, the reduced maximum input voltage (6.0V versus 6.5V) and increased dropout voltage must be evaluated against your specific circuit design. If your input voltage exceeds 6.0V or dropout voltage performance is critical, these parts may not be suitable.

Q: What is the difference between S-T111B23MC-OGITFU and S-1112B23MC-L6ITFU?

A: Both parts are manufactured by ABLIC Inc. with identical electrical specifications (2.3V output, 150mA, 0.35V dropout at 100mA). The difference is packaging format: S-T111B23MC-OGITFU is supplied in Tape & Reel format, while S-1112B23MC-L6ITFU is supplied in Cut Tape format. Electrical performance and PCB footprint compatibility are identical.

Q: Are the SOT-23-5 and SOT-25 packages pin-compatible?

A: Both packages use the SC-74A footprint designation and are mechanically compatible for surface mount assembly. Pin assignments and electrical connections are equivalent for these linear regulator applications.

Q: What is the impact of higher dropout voltage in the Torex parts?

A: Dropout voltage determines the minimum voltage difference required between input and output for proper regulation. XC6215B232MR-G requires 0.65V headroom at 100mA, while XC6504A231MR-G requires 1.05V headroom at 150mA. The S-T111B23MC-OGITFU requires only 0.35V at 100mA. Higher dropout voltage reduces available input voltage margin and increases power dissipation in the regulator.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. S-T111B23MC-OGITFU, S-1112B23MC-L6ITFU, XC6215B232MR-G, and XC6504A231MR-G are all ROHS3 compliant with active product status.
