Substitute Part Grouping Explanation

Substitute parts for the XC6221A26AMR-G are identified based on strict parametric equivalence across the following critical selection criteria:

Electrical Equivalence Requirements:

• Fixed output voltage of 2.65V
• Output current rating of 200mA
• Maximum input voltage of 6V
• Voltage dropout specification of 0.17V @ 100mA
• PSRR of 70dB @ 1kHz
• Enable control feature and over-current protection

Mechanical & Environmental Equivalence Requirements:

• SOT-25 package configuration (SC-74A, SOT-753)
• Surface mount mounting type
• Operating temperature range of -40°C to 85°C
• RoHS3 compliance
• MSL 1 (Unlimited) moisture sensitivity rating

Substitution Logic: The XC6217B26AMR-G qualifies as a parametric equivalent because it maintains all critical electrical specifications (output voltage, current, input voltage, dropout voltage, PSRR, control and protection features) and mechanical specifications (package, mounting type, temperature range, compliance certifications). Variations in quiescent current (8 µA vs. 50 µA) represent an improvement in power efficiency and do not restrict substitution eligibility. Both parts are manufactured by Torex Semiconductor Ltd and share the same base product series characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (XC6221A26AMR-G): The XC6221A26AMR-G is the primary component choice when specified in original designs. This part maintains Active product status with full manufacturing support and is RoHS3 compliant. Current inventory of 1135 units supports immediate procurement requirements.

Substitute Selection (XC6217B26AMR-G): The XC6217B26AMR-G is a direct parametric equivalent suitable for substitution in applications where the XC6221A26AMR-G is unavailable or where reduced quiescent current consumption is beneficial. This part is also Active with RoHS3 compliance and REACH Unaffected status. The reduced quiescent current of 8 µA (compared to 50 µA in the primary part) provides improved power efficiency in battery-powered or low-power standby applications without compromising any critical electrical or mechanical specifications. Current inventory of 783 units is available.

Compliance & Regulatory Basis: Both parts satisfy identical regulatory requirements: RoHS3 compliance, REACH Unaffected status, MSL 1 rating, and EAR99 export classification. Both are manufactured by Torex Semiconductor Ltd and share equivalent HTSUS coding (8542.39.0001).

Frequently Asked Questions (FAQ)

Q: Can the XC6217B26AMR-G be used as a direct replacement for the XC6221A26AMR-G?

A: Yes. The XC6217B26AMR-G is a parametric equivalent with identical output voltage (2.65V), output current (200mA), input voltage rating (6V maximum), voltage dropout (0.17V @ 100mA), PSRR (70dB @ 1kHz), control features (Enable), protection features (Over Current), operating temperature range (-40°C to 85°C), and package configuration (SOT-25). Both parts are surface mount devices with equivalent mechanical and environmental specifications.

Q: What is the difference between these two parts?

A: The primary difference is quiescent current. The XC6221A26AMR-G has a quiescent current of 50 µA, while the XC6217B26AMR-G has a quiescent current of 8 µA. This represents improved power efficiency in the substitute part. All other electrical and mechanical parameters are identical.

Q: Are both parts available in the same package?

A: Yes. Both the XC6221A26AMR-G and XC6217B26AMR-G are packaged in SOT-25 (SC-74A, SOT-753) surface mount configuration. Pin-to-pin compatibility is maintained, allowing direct PCB substitution without layout modifications.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both parts are RoHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Both are classified under HTSUS code 8542.39.0001 and EAR99 export classification.

Q: Which part should I select for new designs?

A: For new designs, either part is acceptable based on availability and application requirements. The XC6217B26AMR-G is recommended when power efficiency and reduced quiescent current consumption are design priorities. The XC6221A26AMR-G is appropriate for applications where the higher quiescent current is not a constraint.

Q: Can I mix these parts in the same production batch?

A: Yes. Both parts are parametrically equivalent and maintain identical electrical performance across all critical specifications. They are interchangeable at the circuit level and can be used interchangeably in production without design or layout changes.

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

A: Both the XC6221A26AMR-G and XC6217B26AMR-G operate across the industrial temperature range of -40°C to 85°C (TA).

Q: Are there any pin configuration differences between these parts?

A: No. Both parts use the SOT-25 package with identical pin configuration (SC-74A, SOT-753). Pin-to-pin compatibility is guaranteed.
