XC6220D331ER-G Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The XC6220D331ER-G is an active linear voltage regulator IC manufactured by Torex Semiconductor Ltd, classified as a Power Management (PMIC) component. This device provides a fixed positive 3.3V output at 1A maximum current in a 6-USPC surface mount package. The part is currently in active production status with 728 units available in new original inventory.

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain disruptions, or procurement optimization. Substitutes must maintain electrical compatibility across critical parameters including output voltage, current capacity, dropout voltage, and thermal characteristics, while maintaining identical mechanical packaging and control feature specifications.

Substitute Part Grouping Explanation

Substitute parts for the XC6220D331ER-G are identified based on strict electrical and mechanical parameter matching. The substitution criteria are defined by the following key parameters:

Critical Matching Parameters:

• Output voltage: 3.3V fixed
• Output current capacity: 1A minimum
• Input voltage maximum: 6V
• Package type: 6-USPC (1.8x2) surface mount
• Control features: Enable function
• Protection features: Over Current and Over Temperature protection
• Operating temperature range: -40°C to 85°C
• Manufacturer: Torex Semiconductor Ltd (same product family)

The XC6220B331ER-G qualifies as a parametric equivalent because it maintains all critical electrical specifications and mechanical compatibility. Variations in quiescent current (18 µA vs. 28.75 µA) and supply current (108 µA vs. 118.75 µA) represent improvements in power efficiency and do not affect functional substitutability in applications designed for the XC6220D331ER-G.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6220D331ER-G and XC6220B331ER-G are active production components manufactured by Torex Semiconductor Ltd and maintain full ROHS3 compliance. Selection between these parts should be based on the following criteria:

XC6220D331ER-G is the primary specification when the design has been validated and qualified against this exact part number. Current inventory of 728 units supports immediate procurement.

XC6220B331ER-G serves as a direct substitute when XC6220D331ER-G availability is constrained. This part demonstrates improved quiescent current performance (18 µA vs. 28.75 µA) and lower maximum supply current (108 µA vs. 118.75 µA), resulting in reduced standby power consumption. With 20,404 units in inventory, this part offers superior supply chain availability. The electrical and mechanical specifications are identical across all critical parameters, ensuring functional compatibility in existing circuit designs without modification.

Both parts are classified as Moisture Sensitivity Level 1 (Unlimited) and carry identical REACH and ECCN designations, confirming regulatory equivalence.

Frequently Asked Questions (FAQ)

Q: Can XC6220B331ER-G be used as a direct replacement for XC6220D331ER-G in production?

A: Yes. Both parts maintain identical output voltage (3.3V), output current (1A), input voltage rating (6V maximum), dropout voltage (0.655V @ 1A), package type (6-USPC), and control/protection features. The parts are electrically and mechanically interchangeable.

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

A: The primary differences are in quiescent current and supply current specifications. XC6220B331ER-G operates at 18 µA quiescent current compared to 28.75 µA for XC6220D331ER-G, and maximum supply current of 108 µA versus 118.75 µA. These represent efficiency improvements in the B-series variant. All other electrical and mechanical parameters are identical.

Q: Are the packages identical?

A: Yes. Both parts use the 6-USPC (1.8x2) surface mount package with identical pinout, footprint, and mechanical dimensions. No PCB layout changes are required when substituting between these parts.

Q: Do both parts have the same certifications?

A: Yes. Both XC6220D331ER-G and XC6220B331ER-G are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: Which part should be selected for new designs?

A: For new designs, XC6220B331ER-G is the preferred selection due to superior power efficiency characteristics (lower quiescent and supply currents) and significantly higher inventory availability (20,404 units vs. 728 units). Both parts are active production components with identical functional specifications.

Q: Is there any performance difference in the output voltage regulation?

A: No. Both parts deliver identical fixed 3.3V output voltage, dropout voltage (0.655V @ 1A), and PSRR (50dB @ 1kHz). Regulation performance is equivalent across the specified operating temperature range (-40°C to 85°C).

Q: Can these parts be used interchangeably in existing designs without circuit modification?

A: Yes. The electrical specifications, package type, pinout, and control features are identical. No circuit modifications, PCB layout changes, or firmware updates are required when substituting between XC6220D331ER-G and XC6220B331ER-G.
