XC6220D321ER-G Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The XC6220D321ER-G is an active linear voltage regulator IC manufactured by Torex Semiconductor Ltd, classified as a Power Management (PMIC) component. This device delivers a fixed positive output of 3.2V at 1A maximum output current in a compact 6-USPC surface mount package. The regulator is designed for applications requiring stable voltage regulation with integrated over-current and over-temperature protection features. As an active product with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1), substitute parts may be required due to inventory constraints, supply chain optimization, or specific performance requirements in production environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XC6220D321ER-G is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Output voltage (Fixed): 3.2V
• Maximum output current: 1A
• Maximum input voltage: 6V
• Package type: 6-USPC (1.8x2) surface mount
• Output configuration: Positive fixed output
• Protection features: Over-current and over-temperature protection
• Control features: Enable function
• Operating temperature range: -40°C to 85°C
• RoHS3 compliance status
• Moisture sensitivity level: MSL 1

The XC6220B321ER-G qualifies as a parametric equivalent substitute because it maintains identical electrical specifications across all critical parameters. Both devices share the same base product number (XC6220), manufacturer (Torex Semiconductor Ltd), and regulatory compliance certifications. Differences in quiescent current (Iq) and supply current (Max) represent performance improvements in the substitute part and do not affect functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6220D321ER-G and XC6220B321ER-G are active products with full regulatory compliance. Selection between these parts should be based on the following engineering criteria:

Primary Selection Criteria:

• Both devices maintain identical electrical performance specifications for voltage regulation, output current capacity, and protection functionality
• Both are RoHS3 compliant with MSL 1 rating, suitable for standard reflow soldering processes without moisture baking requirements
• Both devices are manufactured by Torex Semiconductor Ltd and share the same base product number (XC6220), ensuring design continuity

Secondary Considerations:

• The XC6220B321ER-G demonstrates lower quiescent current (18 µA vs. 28.5 µA) and reduced maximum supply current (108 µA vs. 118.5 µA), resulting in improved power efficiency for battery-powered or low-power applications
• Inventory availability: XC6220D321ER-G has 942 units in stock; XC6220B321ER-G has 854 units in stock
• Both devices are surface mount components in identical 6-USPC (1.8x2) packages, requiring no PCB layout modifications for substitution

Frequently Asked Questions (FAQ)

Q: Can the XC6220B321ER-G be used as a direct replacement for the XC6220D321ER-G?

A: Yes. The XC6220B321ER-G is a parametric equivalent substitute. All critical electrical specifications, output voltage (3.2V), output current (1A), input voltage rating (6V), package type (6-USPC), and protection features are identical. The substitute part demonstrates improved quiescent current performance without affecting functional compatibility.

Q: Are there any PCB layout or design changes required when substituting the XC6220B321ER-G for the XC6220D321ER-G?

A: No design changes are required. Both parts use the identical 6-UFDFN Exposed Pad package with 6-USPC (1.8x2) dimensions. Pin configuration, footprint, and thermal characteristics remain unchanged, allowing direct substitution without PCB modifications.

Q: What is the difference in quiescent current between these two parts?

A: The XC6220D321ER-G has a quiescent current (Iq) of 28.5 µA, while the XC6220B321ER-G has an Iq of 18 µA. This 10.5 µA reduction in the substitute part results in lower standby power consumption, beneficial for applications with extended idle periods or battery operation.

Q: Do both parts have the same regulatory compliance certifications?

A: Yes. Both the XC6220D321ER-G and XC6220B321ER-G are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings. Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: What is the maximum input voltage for these regulators?

A: The maximum input voltage for both the XC6220D321ER-G and XC6220B321ER-G is 6V. The voltage dropout at 1A output current is 0.655V for both devices.

Q: Are these parts suitable for high-temperature applications?

A: Both devices operate across the temperature range of -40°C to 85°C (TA). This range covers standard industrial and commercial temperature requirements. Applications requiring extended temperature ranges beyond 85°C require alternative component selection.

Q: What protection features are included in these regulators?

A: Both the XC6220D321ER-G and XC6220B321ER-G include integrated over-current protection and over-temperature protection. Both devices feature an enable control function for power management applications.
