Engineering Selection Recommendations

For applications currently using S-T111B36MC-OGVTFG, the following selection criteria apply based on product status and compliance:

Primary Recommendation: S-T111B36MC-OGVTFU is the direct equivalent with Active product status, identical electrical specifications, and ROHS3 compliance. This part maintains the same series designation and provides the most direct replacement path.

Secondary Recommendations: S-1112B36MC-L6VTFU and S-1122B36MC-L8VTFU are Active ABLIC alternatives with identical core electrical parameters. Both are ROHS3 compliant. The primary distinction is packaging format (Cut Tape vs. Tape & Reel), which may affect procurement and assembly processes.

Performance-Enhanced Alternative: S-1167B36-M5T1U offers improved performance characteristics with lower dropout voltage (0.21V vs. 0.26V) and reduced quiescent current (900 nA vs. 1 µA), while maintaining Active product status and ROHS3 compliance. This option is suitable for applications requiring lower power consumption or operating closer to minimum input voltage margins.

Cross-Manufacturer Options: RP130N361D-TR-FE and XC6504A361MR-G provide functional equivalence with Active status and appropriate compliance certifications. These options are viable when ABLIC sourcing is constrained. Note that RP130N361D-TR-FE exhibits higher quiescent current (58 µA) and dropout voltage (0.51V), while XC6504A361MR-G has slightly reduced maximum input voltage (6V vs. 6.5V) and higher dropout voltage (0.59V).

Frequently Asked Questions (FAQ)

Q: Can S-1167B36-M5T1U replace S-T111B36MC-OGVTFG directly?

A: Yes. Both parts meet the critical substitution parameters: 3.6V fixed output, 150mA capacity, SOT-23-5 package, and -40°C to 85°C operating range. S-1167B36-M5T1U provides superior performance with lower dropout voltage and quiescent current while maintaining full compatibility.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Both are surface mount packaging formats for the same SOT-23-5 component. Tape & Reel packaging is supplied on continuous tape suitable for automated pick-and-place assembly. Cut Tape is pre-cut tape sections. The electrical specifications and component functionality are identical; the difference is in procurement and assembly logistics.

Q: Are cross-manufacturer parts (Nisshinbo, Torex) fully compatible?

A: Cross-manufacturer parts meet the core electrical requirements: 3.6V output, 150mA capacity, SOT-23-5 package, and operating temperature range. However, they exhibit different quiescent current and dropout voltage characteristics. RP130N361D-TR-FE has higher quiescent current (58 µA vs. 1 µA) and dropout voltage (0.51V vs. 0.26V). XC6504A361MR-G has maximum input voltage of 6V instead of 6.5V and higher dropout voltage (0.59V). These differences may impact power efficiency and minimum input voltage requirements in your application.

Q: Why is S-T111B36MC-OGVTFG marked as Not For New Designs?

A: This designation indicates the part is in mature or end-of-life status. ABLIC recommends using Active alternatives for new designs. S-T111B36MC-OGVTFU (Active variant) or S-1167B36-M5T1U (enhanced performance) are recommended for new applications.

Q: Can I use XC6504A361MR-G if my input voltage is exactly 6V?

A: XC6504A361MR-G has a maximum input voltage specification of 6V, which is the absolute limit. Operation at this boundary may not provide adequate margin for voltage transients or supply variations. For applications with input voltages approaching 6V, ABLIC alternatives with 6.5V maximum input rating provide better design margin.

Q: What compliance certifications apply to all substitute parts?

A: All listed substitute parts are ROHS3 compliant and have MSL rating of 1 (Unlimited moisture sensitivity). REACH status is either REACH Unaffected or not specified. All parts carry ECCN EAR99 and HTSUS 8542.39.0001 classifications.
