Substitute Part Grouping Explanation

Substitute parts for the XC6221B1027R-G are identified based on strict electrical and mechanical parameter matching within the Torex Semiconductor linear regulator family. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Output voltage: 1V fixed
• Output current capability: 200mA
• Maximum input voltage: 6V
• Voltage dropout: 0.65V @ 100mA
• Package type: 4-USPN (0.90x1.2)
• Output configuration: Positive fixed
• Control features: Enable function
• Protection: Over current protection
• PSRR: 70dB (1kHz)
• Operating temperature: -40°C ~ 85°C
• Mounting: Surface mount
• Compliance: RoHS3, REACH Unaffected

The XC6217C1027R-G and XC6217D1027R-G are parametric equivalents within the XC6217 base product series. Both parts maintain identical electrical specifications for output voltage, current, input voltage limits, dropout voltage, PSRR, control features, and protection mechanisms. Package and mounting specifications are identical. The primary difference between these substitutes and the main part is the quiescent current specification, which is lower in the XC6217 variants (8 µA versus 50 µA in the XC6221B1027R-G).

Parameter Comparison

Engineering Selection Recommendations

All three parts—XC6221B1027R-G, XC6217C1027R-G, and XC6217D1027R-G—are Active products from Torex Semiconductor Ltd with identical RoHS3 compliance, REACH Unaffected status, and regulatory classifications (ECCN: EAR99, HTSUS: 8542.39.0001). All parts are MSL 1 rated with unlimited moisture sensitivity handling.

The XC6217C1027R-G and XC6217D1027R-G are direct parametric equivalents for applications requiring the XC6221B1027R-G specifications. The primary distinction is quiescent current: the XC6217 variants operate at 8 µA compared to 50 µA for the XC6221B1027R-G. This lower quiescent current in the XC6217 series may provide power efficiency benefits in standby or low-power operating modes while maintaining identical output voltage, current delivery, dropout voltage, and protection characteristics.

Selection between XC6217C1027R-G and XC6217D1027R-G depends on application-specific availability and supply chain requirements, as both parts are electrically and mechanically identical.

Frequently Asked Questions (FAQ)
