XC6217D3127R-G Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The XC6217D3127R-G is an active linear voltage regulator IC manufactured by Torex Semiconductor Ltd, classified as a Power Management (PMIC) component. This device delivers a fixed positive output of 3.1V at 200mA with integrated enable control and over-current protection. The part is currently in active production status with 690 units in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the same package footprint and functional requirements. Alternative models may be necessary due to inventory constraints, supply chain considerations, or specific performance trade-offs in dropout voltage and quiescent current characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XC6217D3127R-G is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Output voltage: 3.1V fixed
• Output current capacity: 200mA
• Input voltage maximum: 6V
• Package type: 4-XDFN (4-USPN 0.90x1.2)
• Output configuration: Positive fixed
• Control features: Enable function
• Protection features: Over-current protection
• Operating temperature range: -40°C to 85°C
• Mounting type: Surface mount
• RoHS and REACH compliance status

Variable Parameters (Allowed to Differ):

• Dropout voltage at specified current
• Quiescent current (Iq)
• Power Supply Rejection Ratio (PSRR)

The XC6215B3127R-G meets all mandatory matching criteria and is therefore classified as a parametric equivalent. Differences in dropout voltage and quiescent current do not preclude substitution when the application requirements fall within the specified operating ranges of both devices.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6217D3127R-G and XC6215B3127R-G are active production components manufactured by Torex Semiconductor Ltd with identical RoHS3 compliance and REACH unaffected status. Both devices carry MSL Level 1 (unlimited moisture sensitivity), indicating no special storage or handling requirements.

XC6217D3127R-G exhibits superior dropout voltage performance at 0.14V @ 100mA, making it suitable for applications with tight input voltage margins or where thermal dissipation must be minimized. The higher quiescent current of 8µA is offset by lower dropout characteristics.

XC6215B3127R-G provides significantly lower quiescent current at 1.5µA, advantageous for battery-powered or ultra-low-power standby applications. The increased dropout voltage of 0.42V @ 100mA requires verification that input voltage headroom remains adequate for the specific application.

Selection between these equivalents depends on whether dropout voltage performance or quiescent current efficiency is the primary design constraint. Both devices are suitable for direct substitution in applications where the respective performance trade-offs are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the XC6215B3127R-G replace the XC6217D3127R-G in existing designs?

A: Yes, the XC6215B3127R-G is a parametric equivalent. Both devices share identical output voltage, current capacity, package footprint, and control/protection features. Verify that the application can tolerate the increased dropout voltage of 0.42V versus 0.14V at 100mA load current.

Q: What is the primary difference between these two regulators?

A: The XC6217D3127R-G features lower dropout voltage (0.14V @ 100mA) and higher quiescent current (8µA). The XC6215B3127R-G features higher dropout voltage (0.42V @ 100mA) and lower quiescent current (1.5µA). Selection depends on whether the application prioritizes low-dropout performance or ultra-low standby current consumption.

Q: Are both parts available in the same package?

A: Yes. Both the XC6217D3127R-G and XC6215B3127R-G are supplied in the 4-XDFN package (4-USPN 0.90x1.2 mm), enabling direct PCB footprint compatibility without layout modifications.

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

A: No. Both devices use identical surface-mount packaging and thermal characteristics are comparable. Standard linear regulator layout practices apply to both parts.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical MSL Level 1 ratings. No differences exist in regulatory or environmental compliance status.

Q: Which part should be selected for battery-powered applications?

A: The XC6215B3127R-G is preferred for battery-powered designs due to its significantly lower quiescent current (1.5µA versus 8µA), reducing standby power consumption. Confirm that the application input voltage provides sufficient headroom above 3.1V output plus the 0.42V dropout voltage.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that design verification confirms the application requirements fall within the operating parameters of both devices. The primary consideration is dropout voltage performance relative to the minimum input voltage available in the application.
