XC6501C1817R-G Linear Voltage Regulator Equivalent & Substitute Parts

Part Overview

The XC6501C1817R-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 1.8V output at 200mA with integrated enable control and over-current protection. The part is surface-mounted in a 4-USPN (0.90x1.2) package and is RoHS3 compliant with unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across critical parameters including output voltage, current capacity, package form factor, and operating temperature range. Substitution becomes necessary due to inventory availability, supply chain optimization, or design flexibility requirements.

Substitute Part Grouping Explanation

Substitution of the XC6501C1817R-G is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Fixed output voltage of 1.8V
• Output current capacity of 200mA or greater
• Maximum input voltage of 6V or greater
• 4-USPN (0.90x1.2) surface-mount package
• Operating temperature range of -40°C to 85°C or wider
• Enable control feature
• Over-current protection
• RoHS3 compliance
• Unlimited moisture sensitivity rating (MSL 1)

The XC6217D1827R-G meets all mandatory equivalence criteria and is classified as a parametric equivalent. Both devices share identical output voltage, current rating, package geometry, and environmental specifications. Differences in quiescent current, dropout voltage, and PSRR performance do not disqualify substitution when the application requirements fall within the specified operating parameters of both parts.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6501C1817R-G and XC6217D1827R-G are active products with identical compliance certifications (RoHS3, REACH Unaffected, EAR99 ECCN classification). Selection between these parts is based on application-specific performance requirements:

XC6501C1817R-G is suitable for applications where the specified dropout voltage of 0.47V at 200mA and quiescent current of 18µA meet design constraints.

XC6217D1827R-G is suitable for applications requiring lower quiescent current (8µA), improved dropout voltage performance (0.21V at 100mA), and higher power supply rejection ratio (70dB at 1kHz). This part demonstrates enhanced performance characteristics while maintaining full electrical and mechanical compatibility.

Both parts are available in production quantities with unlimited moisture sensitivity rating, eliminating MSL-related handling restrictions. Package geometry, mounting type, and thermal operating range are identical, ensuring direct PCB-level substitution without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the XC6217D1827R-G directly replace the XC6501C1817R-G on an existing PCB?
