XC6220C331ER-G Equivalent & Substitute Parts

Part Overview

The XC6220C331ER-G is a linear voltage regulator IC manufactured by Torex Semiconductor Ltd, classified as a Power Management (PMIC) component. This device provides a fixed positive output of 3.3V at 1A maximum output current in a 6-USPC surface mount package. The regulator features integrated over-current and over-temperature protection with an enable control function, operating across the industrial temperature range of -40°C to 85°C.

The XC6220C331ER-G maintains Active product status with full RoHS3 compliance and REACH unaffected classification. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different manufacturing revisions or product variants within the same base product family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XC6220C331ER-G is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Fixed output voltage of 3.3V
• Maximum output current of 1A
• Maximum input voltage of 6V
• Maximum dropout voltage of 0.655V at 1A
• PSRR of 50dB at 1kHz
• Enable control function
• Over-current and over-temperature protection

Mechanical Equivalence Requirements:

• 6-USPC (1.8x2) package configuration
• Surface mount mounting type
• 6-UFDFN exposed pad case style

Regulatory Equivalence Requirements:

• RoHS3 compliance
• REACH unaffected status
• Active product status

The XC6220B331ER-G qualifies as a parametric equivalent substitute based on identical electrical output specifications, identical package configuration, and equivalent regulatory compliance. Both devices share the same base product number (XC6220) and represent different manufacturing revisions within the same product line.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: XC6220C331ER-G

The XC6220C331ER-G is the specified component and maintains full Active product status with 962 units in current inventory. This part meets all regulatory requirements including RoHS3 compliance and REACH unaffected classification. Selection of this part number is appropriate for new designs and ongoing production where the original specification is maintained.

Substitute Part: XC6220B331ER-G

The XC6220B331ER-G qualifies as a direct parametric equivalent for applications requiring the XC6220C331ER-G. Both parts deliver identical electrical performance in the critical parameters governing regulator function: fixed 3.3V output, 1A maximum current, 6V maximum input, and 0.655V maximum dropout voltage. Both devices feature identical package configuration (6-USPC 1.8x2), identical protection and control features, and equivalent regulatory compliance.

The XC6220B331ER-G represents a manufacturing revision within the XC6220 base product family. The primary difference lies in quiescent current specifications (18 µA versus 28.75 µA) and maximum supply current (108 µA versus 118.75 µA), both of which represent improved performance characteristics in the substitute part. The XC6220B331ER-G maintains Active product status with significantly higher inventory availability (20,404 units).

Selection between these parts depends on design requirements and supply chain considerations. Both parts are suitable for direct substitution in applications where the XC6220C331ER-G was originally specified, provided that the improved quiescent current performance of the XC6220B331ER-G does not conflict with existing design validation or qualification requirements.

Frequently Asked Questions (FAQ)

Q: Can the XC6220B331ER-G be used as a direct replacement for the XC6220C331ER-G?

A: Yes. The XC6220B331ER-G meets all critical electrical and mechanical specifications required for substitution. Both parts deliver 3.3V fixed output at 1A maximum current, operate across -40°C to 85°C, and use identical 6-USPC (1.8x2) surface mount packaging. Both maintain RoHS3 compliance and REACH unaffected status. The substitute part features improved quiescent current performance.

Q: What are the differences between these two parts?

A: The primary differences are manufacturing revision level and quiescent current specifications. The XC6220B331ER-G exhibits lower quiescent current (18 µA versus 28.75 µA) and lower maximum supply current (108 µA versus 118.75 µA). All other electrical parameters, including output voltage, output current, dropout voltage, PSRR, protection features, and control features remain identical.

Q: Are the packages physically identical?

A: Yes. Both parts use the 6-USPC (1.8x2) surface mount package with 6-UFDFN exposed pad configuration. No PCB layout modifications are required for substitution.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the XC6220C331ER-G and XC6220B331ER-G are RoHS3 compliant and REACH unaffected. Both maintain Active product status.

Q: Which part should be selected for new designs?

A: The XC6220B331ER-G is recommended for new designs due to improved quiescent current performance and higher inventory availability. However, if existing design validation or qualification is tied to the XC6220C331ER-G, that part number should be maintained.

Q: Are there any temperature or operating condition differences?

A: No. Both parts operate across the identical temperature range of -40°C to 85°C and provide identical over-current and over-temperature protection.

Q: Can these parts be mixed in the same production batch?

A: Both parts are electrically and mechanically equivalent and maintain identical regulatory compliance. However, production control procedures should be consulted regarding part number management and traceability requirements specific to your manufacturing environment.
