XC6220C321PR-G Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The XC6220C321PR-G is an active linear voltage regulator manufactured by Torex Semiconductor Ltd, classified as a Power Management Integrated Circuit (PMIC). This device delivers a fixed positive output of 3.2V at 1A maximum output current in a surface-mount SOT-89-5 package. The part is currently in active production status with 1090 units available in inventory.

Linear voltage regulators of this specification are essential in applications requiring stable, low-noise DC power supply from higher input voltages. Alternative models become necessary when addressing specific design constraints such as quiescent current optimization, inventory availability, or supply chain considerations while maintaining identical electrical and mechanical compatibility.

Substitute Part Grouping Explanation

The XC6220C321PR-G has one parametric equivalent substitute: XC6220B321PR-G. Both parts share the same manufacturer (Torex Semiconductor Ltd), base product series (XC6220), and are classified within the same product category (Power Management PMIC).

Substitution eligibility is determined by the following critical parameters that must remain identical:

• Output voltage configuration: Positive, Fixed, 3.2V
• Output current rating: 1A
• Maximum input voltage: 6V
• Voltage dropout specification: 0.655V @ 1A
• Package and pinout: SOT-89-5
• Mounting type: Surface Mount
• Control and protection features: Enable function, Over Current and Over Temperature protection
• Operating temperature range: -40°C to 85°C
• Regulatory compliance: RoHS3 Compliant, REACH Unaffected

The substitute part XC6220B321PR-G maintains all these critical parameters, enabling direct functional replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6220C321PR-G and XC6220B321PR-G are active production devices with full regulatory compliance (RoHS3 Compliant, REACH Unaffected). Both parts carry Moisture Sensitivity Level 1, indicating unlimited shelf life under standard storage conditions.

The primary distinction between these parts lies in quiescent current performance. The XC6220B321PR-G exhibits lower quiescent current (18 µA versus 28.5 µA) and lower maximum supply current (108 µA versus 118.5 µA). This difference is significant in battery-powered or ultra-low-power applications where standby current consumption directly impacts system runtime.

Selection between these parts should be based on:

1. Quiescent current requirements: Choose XC6220B321PR-G for applications where minimizing standby power consumption is critical.
2. Inventory availability: Both parts are in active stock; selection may depend on supply chain logistics and lead times.
3. Design validation history: Use the part variant that has been validated in your specific application circuit.

Both parts are electrically and mechanically interchangeable for applications requiring 3.2V, 1A linear regulation with SOT-89-5 surface-mount packaging.

Frequently Asked Questions (FAQ)

Q: Can XC6220B321PR-G directly replace XC6220C321PR-G in existing designs?

A: Yes. Both parts are pin-compatible in SOT-89-5 packaging and share identical electrical specifications for output voltage, output current, input voltage range, dropout voltage, and protection features. No circuit modifications are required for substitution.

Q: What is the significance of the quiescent current difference between these parts?

A: Quiescent current represents the supply current drawn by the regulator when no load is connected. The XC6220B321PR-G draws 18 µA compared to 28.5 µA for the XC6220C321PR-G. In applications with extended idle periods or battery operation, this 10.5 µA reduction directly decreases standby power consumption.

Q: Are both parts suitable for the same temperature range applications?

A: Yes. Both the XC6220C321PR-G and XC6220B321PR-G operate across the identical temperature range of -40°C to 85°C (TA), making them suitable for equivalent thermal environments.

Q: Do these parts have identical package dimensions and pinout?

A: Yes. Both parts use the SOT-89-5 package with identical mechanical dimensions and pin assignments. PCB layout and footprints are directly compatible.

Q: What regulatory certifications apply to both parts?

A: Both parts are RoHS3 Compliant and REACH Unaffected. Both carry Moisture Sensitivity Level 1, indicating unlimited shelf life without special storage requirements.

Q: Are there any performance differences in noise rejection between these parts?

A: No. Both parts specify identical PSRR (Power Supply Rejection Ratio) of 50 dB at 1 kHz, providing equivalent noise filtering performance.

Q: Which part should be selected for new designs?

A: Selection should be based on specific application requirements. For new designs prioritizing low standby power consumption, XC6220B321PR-G is the preferred choice. Both parts are in active production status and suitable for long-term supply continuity.
