Key Parameters

Substitute Part Grouping Explanation

Substitution of the XC6221D1027R-G is valid when the following critical parameters remain constant across all candidate parts:

• Output voltage (fixed at 1V)
• Maximum output current (200mA)
• Maximum input voltage (6V)
• Maximum dropout voltage (0.65V @ 100mA)
• Power supply rejection ratio (70dB at 1kHz)
• Operating temperature range (-40°C to 85°C)
• Package type (4-XDFN / 4-USPN 0.90x1.2)
• Output configuration (Positive Fixed)
• Control features (Enable function)
• Protection features (Over Current protection)
• RoHS3 compliance status
• Moisture sensitivity level (MSL 1)

The XC6217D1027R-G and XC6217C1027R-G are parametric equivalents that maintain all critical electrical specifications and mechanical compatibility. Both parts are manufactured by Torex Semiconductor Ltd and share identical output voltage, current rating, input voltage limits, dropout voltage, PSRR, temperature range, package configuration, and protection features. The primary difference between these substitutes and the main part is the quiescent current specification, which is lower in the XC6217 series (8 µA versus 50 µA in the XC6221D1027R-G).

Parameter Comparison

Engineering Selection Recommendations

All three parts—XC6221D1027R-G, XC6217D1027R-G, and XC6217C1027R-G—are Active products with full RoHS3 compliance and REACH Unaffected status. Each part carries EAR99 export classification and HTSUS code 8542.39.0001, confirming regulatory equivalence.

The XC6217D1027R-G and XC6217C1027R-G are direct substitutes for the XC6221D1027R-G in applications where the lower quiescent current (8 µA versus 50 µA) is acceptable or beneficial. All other electrical and mechanical parameters are identical, ensuring pin-compatible operation within the same PCB footprint and thermal environment.

Selection between XC6217D1027R-G and XC6217C1027R-G depends on inventory availability and lead time requirements. Both parts are functionally equivalent with identical electrical specifications and package configuration.

Frequently Asked Questions (FAQ)

Q: Can the XC6217D1027R-G replace the XC6221D1027R-G in an existing design?

A: Yes. The XC6217D1027R-G is a parametric equivalent with identical output voltage (1V), output current (200mA), input voltage rating (6V maximum), dropout voltage (0.65V @ 100mA), PSRR (70dB at 1kHz), operating temperature range (-40°C to 85°C), and package configuration (4-USPN 0.90x1.2). The primary difference is lower quiescent current (8 µA versus 50 µA), which reduces standby power consumption. No PCB modifications are required.

Q: What is the difference between XC6217D1027R-G and XC6217C1027R-G?

A: Both parts are parametrically identical with respect to output voltage, current rating, input voltage, dropout voltage, PSRR, temperature range, and package type. The designation difference (D versus C) reflects internal design variants within the XC6217 series. Both deliver 8 µA quiescent current and are functionally interchangeable.

Q: Are all three parts pin-compatible?

A: Yes. The XC6221D1027R-G, XC6217D1027R-G, and XC6217C1027R-G all use the 4-USPN (0.90x1.2) package with identical pinout and surface mount footprint. Direct substitution on the PCB is possible without layout changes.

Q: Do these parts have the same compliance certifications?

A: Yes. All three parts are RoHS3 compliant, REACH Unaffected, and carry EAR99 export classification. Moisture sensitivity level is MSL 1 (Unlimited) for all parts, indicating no special storage or handling requirements.

Q: What is the primary advantage of using XC6217 series parts instead of XC6221D1027R-G?

A: The XC6217 series (both D and C variants) operates at 8 µA quiescent current compared to 50 µA in the XC6221D1027R-G. This 6x reduction in standby current consumption is beneficial in battery-powered or low-power applications where quiescent current directly impacts system efficiency and battery life.

Q: Are there any thermal or performance differences between these substitutes?

A: No. All three parts share identical maximum dropout voltage (0.65V @ 100mA), PSRR (70dB at 1kHz), output current capability (200mA), and operating temperature range (-40°C to 85°C). Thermal performance and load regulation characteristics are equivalent across all three parts.

Q: Can I use XC6217C1027R-G if XC6217D1027R-G is unavailable?

A: Yes. The XC6217C1027R-G is a direct functional equivalent to XC6217D1027R-G with identical electrical specifications and package configuration. Both are suitable substitutes for the XC6221D1027R-G.
