Substitute Part Grouping Explanation

Substitute parts for the XC6222D331ER-G are identified as parametric equivalents within the Torex XC6222 linear regulator series. Substitution eligibility is determined by strict equivalence across the following critical parameters:

Substitution Criteria:

• Fixed output voltage: 3.3V
• Maximum output current: 700mA
• Maximum input voltage: 6V
• Dropout voltage specification: 0.2V @ 300mA
• Quiescent current: 220 µA
• PSRR performance: 65dB (1kHz)
• Operating temperature range: -40°C ~ 85°C
• Package configuration: 6-UFDFN Exposed Pad / 6-USPC (1.8x2)
• Control and protection features: Enable, Over Current, Over Temperature, Reverse Polarity
• Regulatory compliance: RoHS3, REACH Unaffected

The XC6222A331ER-G and XC6222B331ER-G variants meet all specified parameters and are classified as direct parametric equivalents. These parts share identical electrical performance characteristics and mechanical compatibility, enabling direct substitution in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

All three parts—XC6222D331ER-G, XC6222A331ER-G, and XC6222B331ER-G—are Active products with identical electrical and mechanical specifications. Selection between these variants is based on availability and supply chain requirements rather than technical differentiation.

Compliance Status: All substitute parts maintain RoHS3 compliance and REACH unaffected classification, meeting regulatory requirements for industrial and commercial applications.

Packaging & Handling: All parts are supplied in Tape & Reel (TR) format with 6-USPC (1.8x2) package dimensions. Moisture Sensitivity Level 1 (Unlimited) indicates no special storage or handling precautions are required.

Inventory Considerations: The XC6222D331ER-G maintains the highest inventory level (20,400 Pcs), followed by XC6222B331ER-G (1,543 Pcs) and XC6222A331ER-G (1,181 Pcs). Component selection should prioritize availability based on project lead times and procurement schedules.

Frequently Asked Questions (FAQ)

Q: Can XC6222A331ER-G and XC6222B331ER-G be used interchangeably with XC6222D331ER-G?

A: Yes. All three parts are parametric equivalents with identical output voltage (3.3V), output current (700mA), dropout voltage (0.2V @ 300mA), and package configuration (6-UFDFN Exposed Pad / 6-USPC 1.8x2). Direct substitution is supported without circuit modification.

Q: Are there any differences in protection features between these parts?

A: No. All three variants include identical protection features: over-current, over-temperature, and reverse polarity protection. Enable control functionality is present on all parts.

Q: What is the significance of the different part number suffixes (D, A, B)?

A: The suffixes indicate internal design revisions within the XC6222 series. These revisions do not alter the electrical performance or mechanical compatibility specified in this document. All variants maintain the same output voltage, current rating, and package footprint.

Q: Do these parts require different PCB layouts or thermal management approaches?

A: No. All three parts share identical package dimensions (6-USPC 1.8x2) and thermal characteristics. PCB layout, trace routing, and thermal design considerations remain unchanged across all variants.

Q: What is the operating temperature range for all substitute parts?

A: All parts operate across -40°C to 85°C (TA). This range is identical across XC6222D331ER-G, XC6222A331ER-G, and XC6222B331ER-G.

Q: Are there any supply chain or lead time advantages to selecting one variant over another?

A: Inventory levels differ: XC6222D331ER-G (20,400 Pcs), XC6222B331ER-G (1,543 Pcs), and XC6222A331ER-G (1,181 Pcs). For applications with extended lead times, the XC6222D331ER-G offers superior availability. For immediate procurement needs, all variants are in stock.

Q: Do these parts comply with current environmental and trade regulations?

A: Yes. All three variants are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001. Regulatory compliance is uniform across all substitute options.
