Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with the S-T111B30MC-OGPTFG across the critical parameters that define functional equivalence. Selection among active alternatives should prioritize product status and compliance certifications.

The S-1112B30MC-L6PTFU, S-1122B30MC-L8PTFU, S-1167A30-M5T1U, S-1167B30-M5T1U, and S-T111B30MC-OGPTFU are all classified as Active products, making them suitable for new production and long-term supply chain planning. The S-1167 series variants offer improved quiescent current performance (900 nA versus 1 µA) and reduced supply current (16 µA versus 90 µA), which may provide advantages in battery-powered or ultra-low-power applications while maintaining the same output specifications.

All substitute parts carry ROHS3 compliance, REACH Unaffected status, and EAR99 classification, matching the regulatory profile of the original part.

Frequently Asked Questions (FAQ)

Q: Can S-1167A30-M5T1U or S-1167B30-M5T1U be used as direct replacements for S-T111B30MC-OGPTFG?

A: Yes. Both S-1167 variants meet all critical electrical and mechanical specifications: 3V fixed output, 150mA current capability, 6.5V maximum input, SOT-23-5 package, and identical operating temperature range. The S-1167 series offers lower quiescent current (900 nA) and supply current (16 µA) compared to the S-T111 series (1 µA and 90 µA respectively), representing a performance improvement within the same functional category.

Q: What is the difference between S-1112B30MC-L6PTFU and S-1122B30MC-L8PTFU?

A: Both parts are parametrically equivalent to the S-T111B30MC-OGPTFG with identical output voltage, current, input voltage, dropout voltage, quiescent current, and supply current specifications. They differ only in series designation (S-1112 versus S-1122) and are both Active products with full ROHS3 compliance.

Q: Are there any package or pinout differences between these substitute parts?

A: No. All substitute parts use the same SC-74A, SOT-753 (SOT-23-5) surface mount package with identical pinout and mechanical dimensions, ensuring direct PCB compatibility without layout modifications.

Q: Why is the original S-T111B30MC-OGPTFG marked as Not For New Designs?

A: This designation indicates the part is in mature or end-of-life status. Active equivalent alternatives from the same manufacturer are available and recommended for new designs and ongoing production to ensure long-term supply chain stability.

Q: Do all substitute parts carry the same compliance certifications?

A: Yes. All listed substitute parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99, matching the regulatory profile of the original S-T111B30MC-OGPTFG.
