Engineering Selection Recommendations

Primary Part: XC6221C1827R-G

Use the XC6221C1827R-G when this specific part number is available and supply is confirmed. This part maintains active production status with 1001 units currently in stock inventory. Full RoHS3 compliance and MSL-1 rating support unrestricted manufacturing environments.

Substitute Part: XC6217D1827R-G

The XC6217D1827R-G is a direct parametric equivalent suitable for substitution in all applications where XC6221C1827R-G is specified. This substitute maintains identical electrical performance across all critical parameters: fixed 1.8V output, 200mA current capacity, 0.21V dropout voltage, and 70dB PSRR. Mechanical compatibility is confirmed through identical 4-XDFN package specifications and surface-mount configuration.

The XC6217D1827R-G demonstrates superior quiescent current performance (8 µA versus 50 µA), resulting in lower standby power consumption. This characteristic provides additional design margin in battery-powered or low-power applications without compromising any specified performance criteria.

Both parts carry identical compliance certifications: ROHS3 compliance, MSL-1 rating, and active product status. Both are manufactured by Torex Semiconductor Ltd, ensuring consistent quality and reliability standards.

Selection Logic:

• Availability-based selection: Choose whichever part is available from authorized inventory
• Performance-based selection: XC6217D1827R-G offers lower quiescent current for equivalent functionality
• Supply-chain flexibility: Maintaining both part numbers in design documentation enables procurement flexibility without design revision

Frequently Asked Questions (FAQ)

Q: Can XC6217D1827R-G replace XC6221C1827R-G in existing designs without modification?

A: Yes. The XC6217D1827R-G is a direct parametric equivalent. All electrical specifications, package dimensions, pin configurations, and operating characteristics are identical.
