Key Parameters

Substitute Part Grouping Explanation

Substitution for the S-L2980A37MC-TF-G is determined by the following critical parameters: fixed output voltage of 3.7V, output current capability, maximum input voltage of 10V, dropout voltage performance, surface mount packaging compatibility, and compliance certifications. Parts are grouped into two categories:

Parametric Equivalent: S-L2980A37MC-TF-U matches all electrical specifications and packaging requirements, differing only in product status (Active vs. Not For New Designs) and tape/reel configuration suffix.

Similar Substitutes: XC6209B372MR-G and XC6209F372MR-G from Torex Semiconductor Ltd provide equivalent 3.7V output and 10V maximum input voltage in compatible SOT-25 packaging. These parts maintain the same output voltage, operating temperature range, and compliance standards. Differences include higher quiescent current (50µA vs. 1µA), higher dropout voltage (0.25V @ 100mA vs. 0.14V @ 50mA), and in the case of XC6209F372MR-G, higher output current capability (300mA vs. 150mA).

Parameter Comparison

Engineering Selection Recommendations

S-L2980A37MC-TF-U is the direct parametric equivalent and primary substitute. It maintains identical electrical performance and packaging while offering active product status and continued manufacturer support. This part is suitable for direct replacement in existing designs without circuit modification.

XC6209B372MR-G provides functional equivalence with identical output voltage and current specifications. The higher quiescent current (50µA) and dropout voltage (0.25V @ 100mA) represent measurable differences that may impact power efficiency in battery-powered applications. The SOT-25 package requires PCB layout adjustment compared to SOT-23-5. This part is appropriate for applications where the specified current and voltage parameters are sufficient and layout accommodation is feasible.

XC6209F372MR-G offers increased output current capability (300mA) while maintaining the same 3.7V output voltage and 10V maximum input voltage. The higher quiescent current and dropout voltage apply similarly to XC6209B372MR-G. This part is suitable for applications requiring higher current delivery or where future current margin is desired.

All substitute parts maintain ROHS3 compliance and the specified operating temperature range, ensuring regulatory and environmental compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can S-L2980A37MC-TF-U be used as a direct replacement for S-L2980A37MC-TF-G?

A: Yes. S-L2980A37MC-TF-U is a parametric equivalent with identical electrical specifications, output voltage, current rating, dropout voltage, and packaging. The primary difference is product status (Active vs. Not For New Designs) and tape/reel configuration. No circuit modifications are required.

Q: What are the key differences between the ABLIC S-L2980 and Torex XC6209 series?

A: Both series provide 3.7V fixed output with 10V maximum input voltage and -40°C to 85°C operating range. The S-L2980A37MC-TF-G features lower quiescent current (1µA vs. 50µA) and lower dropout voltage (0.14V @ 50mA vs. 0.25V @ 100mA). The XC6209 series includes over-current protection and higher PSRR (70dB @ 10kHz vs. 65dB @ 1kHz). Package differences exist: S-L2980 uses SOT-23-5 while XC6209 uses SOT-25.

Q: Is the SOT-25 package compatible with SOT-23-5 PCB layouts?

A: No. SOT-25 and SOT-23-5 are different package footprints with different pin counts and spacing. PCB layout modification is required when substituting between these packages. Verify pin assignments and spacing before implementing XC6209 series parts.

Q: Which substitute part should be selected for battery-powered applications?

A: S-L2980A37MC-TF-U is preferred for battery-powered applications due to its lower quiescent current (1µA) and lower dropout voltage (0.14V @ 50mA), which reduce power consumption compared to XC6209 series alternatives (50µA quiescent current, 0.25V dropout voltage).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. S-L2980A37MC-TF-U, XC6209B372MR-G, and XC6209F372MR-G are all ROHS3 compliant and REACH unaffected, maintaining regulatory compatibility with the original S-L2980A37MC-TF-G.

Q: What is the difference between XC6209B372MR-G and XC6209F372MR-G?

A: Both parts share identical electrical characteristics except for output current capability. XC6209B372MR-G provides 150mA output current, matching the original part specification. XC6209F372MR-G provides 300mA output current, offering increased current capacity for applications requiring higher power delivery.
