XC6501B3117R-G Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The XC6501B3117R-G is an active linear voltage regulator IC manufactured by Torex Semiconductor Ltd, classified as a Power Management (PMIC) component. This device provides a fixed positive output of 3.1V at 200mA output current in a compact 4-USPN surface mount package. The part is currently in active production status with 747 units in stock inventory.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the same functional category. Alternative models may be required due to inventory constraints, supply chain optimization, or specific application requirements where parametric performance remains within acceptable operating ranges.

Substitute Part Grouping Explanation

Substitute parts for the XC6501B3117R-G are identified based on strict parametric equivalence within the linear voltage regulator category. The substitution logic is based on the following critical parameters that must remain constant or within acceptable tolerances:

Fixed Parameters (Must Match Exactly):

• Output voltage: 3.1V fixed
• Output current capability: 200mA minimum
• Input voltage maximum: 6V
• Package type: 4-XDFN (4-USPN 0.90x1.2)
• Output configuration: Positive fixed single output
• Control features: Enable function
• Protection features: Over current protection
• Operating temperature range: -40°C to 85°C
• Mounting type: Surface mount
• RoHS compliance: ROHS3 Compliant

Variable Parameters (Acceptable Variance):

• Dropout voltage: Variance permitted within application requirements
• Quiescent current: Lower values acceptable for power-sensitive applications
• PSRR (Power Supply Rejection Ratio): Not required for all substitutes

The XC6215B3127R-G meets all fixed parameter requirements and maintains functional equivalence for direct substitution in applications where the specified electrical characteristics are compatible.

Engineering Selection Recommendations

Primary Part: XC6501B3117R-G

The XC6501B3117R-G is the specified component and remains the first choice for applications requiring the exact parametric profile. This part is active in production, ROHS3 compliant, and maintains full regulatory compliance under REACH and EAR99 classifications.

Substitute Part: XC6215B3127R-G

The XC6215B3127R-G is a direct parametric equivalent suitable for substitution in applications where the following conditions are met:

• Fixed output voltage of 3.1V is required
• Maximum output current requirement does not exceed 200mA
• Input voltage does not exceed 6V
• 4-USPN package footprint compatibility is maintained
• Operating temperature range of -40°C to 85°C is acceptable

The XC6215B3127R-G offers improved quiescent current performance (1.5µA versus 21µA), making it advantageous for battery-powered or low-power standby applications. Both parts maintain identical RoHS3 compliance and regulatory status.

Frequently Asked Questions (FAQ)

Q: Can XC6215B3127R-G replace XC6501B3117R-G in all applications?

A: The XC6215B3127R-G is a parametric equivalent for applications requiring 3.1V fixed output at up to 200mA. Both parts share identical output voltage, current rating, package type, and operating temperature range. The substitute part features lower quiescent current (1.5µA vs 21µA) and slightly higher dropout voltage at reduced load (0.42V @ 100mA vs 0.36V @ 200mA). Substitution is valid when these electrical characteristics are compatible with circuit requirements.

Q: Are the package dimensions identical between these parts?

A: Both XC6501B3117R-G and XC6215B3127R-G use the 4-XDFN package with supplier designation 4-USPN (0.90x1.2mm). PCB footprints and land patterns are identical, enabling direct mechanical substitution without layout modifications.

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

A: The XC6501B3117R-G draws 21µA quiescent current, while the XC6215B3127R-G draws 1.5µA. The XC6215B3127R-G is preferred in applications where standby power consumption is critical. Both values are within acceptable ranges for linear regulator applications.

Q: Do both parts have the same regulatory compliance?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is 1 (unlimited) for both components. Regulatory status is identical.

Q: What is the dropout voltage specification for each part?

A: The XC6501B3117R-G specifies 0.36V maximum dropout at 200mA load current. The XC6215B3127R-G specifies 0.42V maximum dropout at 100mA load current. For applications operating at full 200mA output, verify that the XC6215B3127R-G dropout voltage remains acceptable for your input voltage margin.

Q: Are both parts currently in stock?

A: Yes. XC6501B3117R-G has 747 units in stock, and XC6215B3127R-G has 848 units in stock. Both are available as new original components in tape and reel packaging.
