Engineering Selection Recommendations

Primary Selection: XC6217C3127R-G

The XC6217C3127R-G is the specified component and remains the first choice for new designs. Both the main part and substitute are manufactured by Torex Semiconductor Ltd and maintain active production status. Both devices carry identical RoHS3 compliance, MSL 1 rating, and REACH unaffected status, ensuring regulatory compliance across applications.

Substitute Selection: XC6215B3127R-G

The XC6215B3127R-G is a valid parametric equivalent when the XC6217C3127R-G is unavailable. Key differences exist in performance characteristics:

• The XC6215B3127R-G exhibits higher voltage dropout (0.42V vs. 0.14V at 100mA), which may impact applications with tight input-to-output voltage margins or high-current transient conditions.
• The XC6215B3127R-G demonstrates lower quiescent current (1.5 µA vs. 8 µA), providing improved efficiency in battery-powered or low-power standby applications.

Both parts share identical output voltage, current rating, package dimensions, operating temperature range, and protection features. Substitution is mechanically and electrically compatible at the board level. Selection between these parts depends on application-specific requirements regarding dropout voltage performance versus quiescent current efficiency.

Frequently Asked Questions (FAQ)

Q: Can XC6215B3127R-G directly replace XC6217C3127R-G in existing designs?

A: Yes, direct replacement is possible from a mechanical and functional standpoint. Both parts use identical 4-XDFN packaging and provide the same 3.1V, 200mA output. However, the higher dropout voltage of the XC6215B3127R-G (0.42V vs. 0.14V) may affect circuit performance if the design operates near minimum input voltage margins. Verify that your input voltage headroom accommodates the increased dropout specification.

Q: What is the primary difference between these two parts?

A: The XC6217C3127R-G features lower dropout voltage (0.14V @ 100mA) and higher quiescent current (8 µA), while the XC6215B3127R-G features higher dropout voltage (0.42V @ 100mA) and lower quiescent current (1.5 µA). The XC6217C3127R-G is optimized for applications requiring minimal voltage loss across the regulator. The XC6215B3127R-G is optimized for low-power applications where quiescent current efficiency is critical.

Q: Are both parts available in the same package?

A: Yes. Both XC6217C3127R-G and XC6215B3127R-G are supplied in 4-XDFN packaging with identical physical dimensions (4-USPN 0.90x1.2mm). PCB footprints are identical, and no layout modifications are required for substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS3 compliant, carry MSL 1 (unlimited moisture sensitivity level), and are REACH unaffected. Regulatory compliance is equivalent across both components.

Q: Which part should I select for a new design?

A: Use the XC6217C3127R-G as the primary selection for new designs. This is the specified part number and offers superior dropout voltage performance. Reserve the XC6215B3127R-G for applications where quiescent current efficiency is the dominant design constraint or when the primary part is unavailable.

Q: Can I use XC6215B3127R-G in a high-current application?

A: Both parts are rated for 200mA output current and include over-current protection. However, the higher dropout voltage of the XC6215B3127R-G means greater power dissipation at maximum current. Verify thermal performance and ensure adequate heat dissipation for your specific current profile.

Q: Is PSRR performance equivalent between these parts?

A: The XC6217C3127R-G specifies PSRR of 70dB at 1kHz. The XC6215B3127R-G does not provide PSRR specification in the available data. If power supply rejection ratio is critical to your application, the XC6217C3127R-G is the appropriate selection.
