XC6501D3117R-G Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The XC6501D3117R-G is a linear voltage regulator IC manufactured by Torex Semiconductor Ltd, designed for positive fixed output applications. This device delivers 200mA output current at a fixed 3.1V output voltage in a compact 4-USPN surface mount package. The regulator is currently in active production status with 765 units available in inventory.

Alternative equivalent parts may be required due to component availability constraints, supply chain disruptions, or specific application requirements where substitute devices meet the electrical and mechanical specifications of the original design.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the XC6501D3117R-G is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Output voltage: 3.1V fixed
• Output current capability: 200mA minimum
• Maximum input voltage: 6V
• Package type: 4-XDFN (4-USPN 0.90x1.2)
• Output configuration: Positive fixed
• Number of regulators: 1
• Control features: Enable function
• Protection features: Over current protection
• Operating temperature range: -40°C to 85°C
• Mounting type: Surface mount
• Compliance: ROHS3, REACH Unaffected

Allowable Parameter Variations: Substitute parts may differ in the following parameters while maintaining functional equivalence:

• Voltage dropout (Max): Variation permitted if specification remains within acceptable design margins
• Quiescent current (Iq): Lower values are acceptable and represent improved performance
• PSRR: Variation permitted; absence of specification does not disqualify substitution

The XC6215B3127R-G meets all mandatory matching parameters and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

XC6501D3117R-G Selection Criteria:

• Primary choice when original part number specification is required
• Active production status with 765 units in current inventory
• ROHS3 compliant and REACH unaffected
• Specified PSRR of 50dB at 1kHz for noise-sensitive applications
• Quiescent current of 21µA

XC6215B3127R-G Selection Criteria:

• Functionally equivalent substitute when XC6501D3117R-G is unavailable
• Active production status with 848 units in current inventory
• ROHS3 compliant and REACH unaffected
• Superior quiescent current performance at 1.5µA (14x lower than main part)
• Acceptable for applications where PSRR specification is not critical
• Dropout voltage specification at 100mA rather than 200mA; verify margin requirements in final design

Both parts are manufactured by Torex Semiconductor Ltd and share identical mechanical and thermal specifications. Selection between these devices depends on component availability and specific application requirements for quiescent current performance and noise rejection characteristics.

Frequently Asked Questions (FAQ)

Q: Can XC6215B3127R-G be used as a direct replacement for XC6501D3117R-G?

A: Yes. Both devices are pin-compatible in the 4-USPN (0.90x1.2) package and deliver identical output voltage (3.1V) and current (200mA) specifications. The XC6215B3127R-G qualifies as a parametric equivalent substitute based on matching all mandatory electrical and mechanical parameters.

Q: What are the differences between these two parts?

A: The primary differences are quiescent current (XC6215B3127R-G: 1.5µA vs. XC6501D3117R-G: 21µA) and PSRR specification (XC6501D3117R-G specifies 50dB at 1kHz; XC6215B3127R-G does not specify this parameter). Dropout voltage is specified at different load points: XC6501D3117R-G at 200mA (0.36V) and XC6215B3127R-G at 100mA (0.42V).

Q: Are both parts RoHS compliant?

A: Yes. Both XC6501D3117R-G and XC6215B3127R-G are ROHS3 compliant with MSL rating of 1 (Unlimited). Both are REACH unaffected.

Q: Which part should I select for low-power applications?

A: The XC6215B3127R-G is superior for low-power applications due to its significantly lower quiescent current of 1.5µA compared to 21µA in the XC6501D3117R-G.

Q: Are there any package or pinout differences?

A: No. Both parts use identical 4-XDFN packaging with 4-USPN (0.90x1.2) dimensions. Pinout and mechanical specifications are identical, enabling direct PCB layout compatibility.

Q: What is the operating temperature range for both parts?

A: Both devices operate across -40°C to 85°C (TA), providing identical thermal specifications for industrial and commercial applications.

Q: Can I use these parts interchangeably in production?

A: Yes, provided your design does not have critical dependencies on the PSRR specification or specific dropout voltage characteristics at 200mA load. Verify dropout voltage margins at your maximum load current before final design release.
