Substitute Part Grouping Explanation

Substitute parts for the XC6220C321ER-G are identified as parametric equivalents within the Torex XC6220 base product family. Substitution eligibility is determined by strict matching of the following critical parameters:

Electrical Specifications (Must Match):

• Output voltage: 3.2V fixed
• Maximum output current: 1A
• Maximum input voltage: 6V
• Maximum dropout voltage: 0.655V @ 1A
• Output configuration: Positive fixed single output
• Protection features: Over current and over temperature protection
• Control features: Enable input

Physical & Environmental Specifications (Must Match):

• Package type: 6-USPC (1.8x2) surface mount
• Operating temperature range: -40°C to 85°C
• Moisture sensitivity level: MSL 1 (Unlimited)

Regulatory & Compliance (Must Match):

• RoHS3 compliance
• REACH unaffected status
• ECCN: EAR99 classification

Substitute parts may exhibit variations in quiescent current (Iq) and maximum supply current (Imax) specifications within the same product series, provided all critical electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6220C321ER-G and XC6220B321ER-G are Active products with identical electrical performance specifications, package configuration, and regulatory compliance status. Selection between these parts is based on the following engineering criteria:

Primary Selection Criteria:

The XC6220B321ER-G exhibits lower quiescent current (18 µA versus 28.5 µA) and lower maximum supply current (108 µA versus 118.5 µA). This variant is suitable for applications where standby power consumption and overall system efficiency are critical design parameters.

The XC6220C321ER-G maintains standard quiescent current specifications and is suitable for general-purpose linear regulation applications where power efficiency optimization is not a primary constraint.

Compliance & Availability:

Both parts maintain full RoHS3 compliance, REACH unaffected status, and unlimited moisture sensitivity rating (MSL 1), confirming suitability for industrial and commercial applications without additional handling or storage restrictions.

Current inventory status shows 952 units of XC6220C321ER-G and 854 units of XC6220B321ER-G available as new original stock, supporting immediate procurement for both variants.

Frequently Asked Questions (FAQ)

Q: Can the XC6220B321ER-G directly replace the XC6220C321ER-G in existing designs?

A: Yes. Both parts share identical output voltage (3.2V), output current (1A), input voltage rating (6V maximum), dropout voltage (0.655V @ 1A), package configuration (6-USPC), and protection features. The XC6220B321ER-G exhibits lower quiescent current, making it functionally compatible for direct substitution without circuit modification.

Q: What is the primary difference between these two part numbers?

A: The XC6220B321ER-G features reduced quiescent current (18 µA) and maximum supply current (108 µA) compared to the XC6220C321ER-G (28.5 µA and 118.5 µA respectively). All other electrical and mechanical specifications remain identical.

Q: Are both parts available in the same package configuration?

A: Yes. Both the XC6220C321ER-G and XC6220B321ER-G are supplied in 6-USPC (1.8x2) surface mount packages with exposed pad configuration. PCB layout and footprint requirements are identical.

Q: Do these parts require different handling or storage procedures?

A: No. Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control or baking procedures are required during storage or handling.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the XC6220C321ER-G and XC6220B321ER-G are fully RoHS3 compliant with REACH unaffected status, confirming suitability for regulated markets and applications requiring environmental compliance documentation.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the temperature range of -40°C to 85°C (TA), supporting industrial and extended commercial temperature applications.

Q: Can these parts be used interchangeably in high-volume production?

A: Yes. Both parts are Active products with identical electrical specifications, package configuration, and regulatory compliance. Production designs can specify either part number with equivalent functional performance. The lower quiescent current of the XC6220B321ER-G may provide efficiency advantages in battery-powered or low-power standby applications.
