Electrical Equivalence Criteria:

• Fixed output voltage of 1.8V
• Output current rating of 200mA minimum
• Maximum input voltage of 6V or greater
• Dropout voltage specification of 0.21V @ 100mA or lower
• PSRR of 70dB @ 1kHz
• Over current protection feature
• Enable control feature

Mechanical Equivalence Criteria:

• 4-XDFN package type (4-USPN 0.90x1.2 footprint)
• Surface mount configuration
• Tape & Reel packaging format

Compliance Equivalence Criteria:

• ROHS3 compliance
• Active product status
• Operating temperature range of -40°C to 85°C

The XC6217D1827R-G meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

XC6221D1827R-G (Primary Part): This part is recommended as the primary selection. It maintains active production status with 2400 units in current inventory. Full ROHS3 compliance and REACH unaffected status confirm regulatory alignment. The device meets all specified electrical and mechanical parameters for 1.8V, 200mA linear regulation applications.

XC6217D1827R-G (Substitute Part): This part is qualified as a direct substitute. It provides identical electrical performance across all critical parameters including output voltage, current rating, dropout voltage, and protection features. The XC6217D1827R-G features a lower quiescent current specification (8 µA versus 50 µA), which represents an operational advantage in low-power standby scenarios. Package compatibility, compliance certifications, and operating temperature range are fully equivalent. Current inventory of 842 units is available.

Both parts are manufactured by Torex Semiconductor Ltd and share the same base product family lineage (XC6221 and XC6217 series respectively), ensuring design consistency and long-term supply reliability.
