Substitute Part Grouping Explanation

Substitute parts for the XC6221C26AMR-G are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Output voltage (fixed): 2.65V
• Maximum output current: 200mA
• Maximum input voltage: 6V
• Voltage dropout: 0.17V @ 100mA
• Package type: SOT-25 (SC-74A, SOT-753)
• Output configuration: Positive fixed
• Number of regulators: 1
• Control features: Enable function
• Protection features: Over current protection
• Operating temperature range: -40°C ~ 85°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The XC6217B26AMR-G qualifies as a parametric equivalent because it maintains identical electrical specifications across all critical parameters listed above. Both devices are manufactured by Torex Semiconductor Ltd and share the same base product lineage, ensuring design compatibility and functional interchangeability within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6221C26AMR-G and XC6217B26AMR-G are active production devices manufactured by Torex Semiconductor Ltd with full ROHS3 compliance and unlimited moisture sensitivity rating. Selection between these parts is based on the following engineering criteria:

Primary Selection (XC6221C26AMR-G): Choose this part when inventory availability is the primary consideration, as 1009 units are currently in stock. This part maintains all specified electrical and mechanical parameters for applications requiring a 2.65V, 200mA linear regulator in SOT-25 packaging.

Alternative Selection (XC6217B26AMR-G): This substitute part is electrically and mechanically equivalent with identical critical parameters. The quiescent current specification is lower (8 µA versus 50 µA), which may provide marginal power efficiency benefits in battery-powered or low-power standby applications. This part is available with 783 units in inventory.

Both parts operate across the full temperature range of -40°C to 85°C and include enable control and over-current protection features. Selection should be based on immediate availability requirements and application-specific power consumption priorities.

Frequently Asked Questions (FAQ)

Q: Can XC6217B26AMR-G be used as a direct replacement for XC6221C26AMR-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), package type (SOT-25), operating temperature range (-40°C to 85°C), and compliance certifications (ROHS3, MSL 1). Both devices are pin-compatible and functionally interchangeable in circuit designs.

Q: What is the difference between these two parts?

A: The primary difference is the quiescent current specification. The XC6221C26AMR-G has a quiescent current of 50 µA, while the XC6217B26AMR-G has a quiescent current of 8 µA. All other electrical and mechanical parameters are identical. The lower quiescent current in the XC6217B26AMR-G may reduce standby power consumption in applications where the regulator operates continuously.

Q: Are both parts available in the same package?

A: Yes. Both the XC6221C26AMR-G and XC6217B26AMR-G are supplied in SOT-25 packaging (SC-74A, SOT-753 case designation). They are pin-compatible and require no PCB layout modifications for substitution.

Q: Do both parts have the same compliance certifications?

A: Yes. Both parts are ROHS3 compliant, have MSL rating of 1 (Unlimited), and are REACH unaffected. Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: Which part should I select if both are available?

A: Selection depends on application requirements. If quiescent current is not a design constraint, either part is suitable. If inventory availability is critical, the XC6221C26AMR-G has higher stock levels (1009 units). If lower standby power consumption is required, the XC6217B26AMR-G offers reduced quiescent current (8 µA versus 50 µA).

Q: Are there any temperature or operating condition differences?

A: No. Both parts operate identically across the full temperature range of -40°C to 85°C and maintain the same PSRR specification of 70dB at 1kHz. Both include enable control and over-current protection features.
