Engineering Selection Recommendations

The XC6220B321PR-G is a direct parametric equivalent to the XC6220D321PR-G for applications requiring a 3.2V, 1A linear voltage regulator in SOT-89-5 packaging. Both devices are manufactured by Torex Semiconductor Ltd and maintain identical electrical performance specifications for output voltage, output current, input voltage rating, and dropout voltage.

Compliance & Regulatory Status: Both parts maintain Active product status and are fully compliant with RoHS3 and REACH requirements. Moisture sensitivity level is identical at MSL 1 (Unlimited), indicating no special handling requirements during storage or assembly.

Functional Equivalence: The devices are functionally equivalent across all critical parameters: enable control capability, over-current protection, over-temperature protection, and operating temperature range (-40°C to 85°C). Power supply rejection ratio (PSRR) is identical at 50dB (1kHz).

Secondary Parameter Differences: The XC6220B321PR-G exhibits lower quiescent current (18 µA versus 28.5 µA) and lower maximum supply current (108 µA versus 118.5 µA). These differences represent improved power efficiency in the B-series variant and do not affect substitution eligibility. The lower quiescent current may provide marginal benefits in battery-powered or low-power standby applications.

Selection Basis: Component selection between these equivalents should be based on inventory availability, lead time, and cost considerations. The XC6220B321PR-G currently maintains higher inventory (1172 Pcs) compared to the XC6220D321PR-G (686 Pcs), which may influence procurement decisions.

Frequently Asked Questions (FAQ)

Q: Can the XC6220B321PR-G replace the XC6220D321PR-G in existing designs without circuit modification?

A: Yes. The XC6220B321PR-G is a parametric equivalent with identical output voltage (3.2V), output current (1A), input voltage rating (6V), dropout voltage (0.655V @ 1A), and package type (SOT-89-5). No circuit modifications are required for direct substitution.

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

A: Both parts use the SOT-89-5 package with identical pin assignments. Pin-for-pin compatibility is confirmed.

Q: What is the significance of the different quiescent current values?

A: The XC6220B321PR-G has lower quiescent current (18 µA) compared to the XC6220D321PR-G (28.5 µA). This represents improved power efficiency and may reduce standby power consumption in applications where the regulator is continuously powered but not delivering full load current. This difference does not affect functional equivalence or substitution suitability.
