Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S-L2980A39MC-TF-G is determined by the following critical parameters: fixed output voltage of 3.9V, output current rating, maximum input voltage of 10V, operating temperature range of -40°C to 85°C, surface mount packaging compatibility, and regulatory compliance (ROHS3).

The substitute parts are grouped into two categories:

Parametric Equivalent: S-L2980A39MC-TF-U shares identical electrical specifications and differs only in product status (Active vs. Not For New Designs) and packaging designation (TF-U vs. TF-G). This part maintains 100% functional compatibility.

Similar Substitutes: XC6209B392MR-G and XC6209F392MR-G are manufactured by Torex Semiconductor Ltd and provide equivalent 3.9V fixed output with Enable control and ROHS3 compliance. These parts operate within the same temperature range and input voltage specifications but differ in output current capacity and certain electrical characteristics (dropout voltage, quiescent current, PSRR).

Parameter Comparison

Engineering Selection Recommendations

S-L2980A39MC-TF-U is the primary substitute for the S-L2980A39MC-TF-G. Both parts are from the same manufacturer series with identical electrical and thermal specifications. The key distinction is product status: S-L2980A39MC-TF-U is Active, providing long-term availability assurance compared to the Not For New Designs status of the original part. This substitution requires no circuit modifications and maintains full compatibility.

XC6209B392MR-G provides functional equivalence with the same 3.9V output and 150mA current rating. This Torex part is Active and ROHS3 compliant. Design considerations include higher quiescent current (50 µA vs. 1 µA), higher dropout voltage (0.25V @ 100mA vs. 0.14V @ 50mA), and inclusion of over-current protection. The SOT-25 package differs from SOT-23-5, requiring PCB layout modification.

XC6209F392MR-G offers increased output current capacity (300mA vs. 150mA) while maintaining the 3.9V fixed output and Active product status. This part is suitable for applications requiring higher current delivery. Like XC6209B392MR-G, it features over-current protection and operates in SOT-25 packaging. The higher quiescent current and dropout voltage specifications apply.

All substitute parts maintain ROHS3 compliance and operate across the required -40°C to 85°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can S-L2980A39MC-TF-U be used as a direct replacement for S-L2980A39MC-TF-G?

A: Yes. Both parts share identical electrical specifications, output voltage, current rating, dropout voltage, and operating temperature range. The only difference is product status (Active vs. Not For New Designs). No circuit modifications are required.

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

A: The primary differences are quiescent current (1 µA for S-L2980 vs. 50 µA for XC6209), dropout voltage characteristics (0.14V @ 50mA vs. 0.25V @ 100mA), and protection features (none vs. over-current). The XC6209 parts also use SOT-25 packaging instead of SOT-23-5.

Q: Can XC6209B392MR-G and XC6209F392MR-G be used interchangeably?

A: No. XC6209B392MR-G is rated for 150mA output current, matching the original S-L2980A39MC-TF-G specification. XC6209F392MR-G is rated for 300mA and is suitable only for applications requiring higher current delivery. Selection depends on circuit current requirements.

Q: Does the SOT-25 package of XC6209 parts affect compatibility?

A: Yes. SOT-25 and SOT-23-5 packages have different pin configurations and physical dimensions. PCB layout and footprint modifications are required when substituting XC6209 parts. Verify pin assignments and spacing before implementation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. S-L2980A39MC-TF-U, XC6209B392MR-G, and XC6209F392MR-G are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute offers the best long-term availability?

A: S-L2980A39MC-TF-U is the recommended choice for long-term availability, as it is from the same manufacturer series and carries Active product status. Both Torex XC6209 variants are also Active but represent a different manufacturer platform.
