XC6501A26AMR-G Equivalent & Substitute Parts

Part Overview

The XC6501A26AMR-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 2.65V at 200mA maximum current in a surface-mount SOT-25 package. The regulator includes enable control and over-current protection features, operating across the industrial temperature range of -40°C to 85°C.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across critical parameters including output voltage, maximum output current, input voltage rating, dropout voltage characteristics, and package form factor. Identification of suitable alternatives ensures design flexibility, supply chain continuity, and access to components with potentially improved performance characteristics within the same functional class.

Substitute Part Grouping Explanation

Substitution eligibility for the XC6501A26AMR-G is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Fixed output voltage of 2.65V
• Maximum output current rating of 200mA or greater
• Maximum input voltage rating of 6V or greater
• Surface-mount package type SOT-25 (SC-74A, SOT-753)
• Operating temperature range encompassing -40°C to 85°C
• Presence of enable control functionality
• Presence of over-current protection

Allowable Variation Parameters:

• Dropout voltage (lower values indicate improved performance)
• Quiescent current (lower values indicate reduced standby power consumption)
• Power Supply Rejection Ratio (PSRR) at 1kHz (higher values indicate superior noise rejection)

The XC6217B26AMR-G meets all mandatory equivalence criteria and demonstrates improved performance in dropout voltage, quiescent current, and PSRR characteristics, qualifying it as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6501A26AMR-G and XC6217B26AMR-G are active products manufactured by Torex Semiconductor Ltd with identical RoHS3 compliance and REACH unaffected status. Both components maintain MSL Level 1 (Unlimited) moisture sensitivity classification, indicating no special storage or handling requirements.

The XC6217B26AMR-G demonstrates superior electrical performance characteristics within the same functional specification:

• Dropout voltage reduced to 0.17V at 100mA (compared to 0.38V at 200mA for the primary part)
• Quiescent current reduced to 8µA (compared to 20µA)
• Power Supply Rejection Ratio improved to 70dB at 1kHz (compared to 50dB)

Both parts are supplied in identical SOT-25 packaging with equivalent pinout and control feature sets. Selection between these components depends on application-specific requirements for power efficiency, noise performance, and thermal management rather than functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the XC6217B26AMR-G be used as a direct replacement for the XC6501A26AMR-G?

A: Yes. Both components deliver identical fixed output voltage (2.65V), maximum output current (200mA), maximum input voltage (6V), and operate across the same temperature range (-40°C to 85°C). Both include enable control and over-current protection in the same SOT-25 package. The XC6217B26AMR-G is a parametric equivalent with improved performance characteristics.

Q: What are the key differences between these two parts?

A: The primary differences are performance enhancements in the XC6217B26AMR-G: lower dropout voltage (0.17V vs. 0.38V), reduced quiescent current (8µA vs. 20µA), and higher PSRR (70dB vs. 50dB). These improvements reduce power dissipation and enhance noise rejection without changing functional operation or package form factor.

Q: Are the pinouts identical between XC6501A26AMR-G and XC6217B26AMR-G?

A: Both components use the SOT-25 package (SC-74A, SOT-753) with identical pin configuration. No PCB layout modifications are required for substitution.

Q: Do both parts have the same compliance certifications?

A: Yes. Both the XC6501A26AMR-G and XC6217B26AMR-G are ROHS3 compliant, REACH unaffected, and classified as MSL Level 1 (Unlimited). Both carry ECCN EAR99 classification and HTSUS code 8542.39.0001.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. The XC6217B26AMR-G is preferred for applications requiring lower power consumption, reduced thermal dissipation, or superior power supply noise rejection. The XC6501A26AMR-G remains suitable for applications where these performance enhancements are not critical.

Q: Are there any temperature or environmental restrictions for either part?

A: Both parts operate across the industrial temperature range of -40°C to 85°C with MSL Level 1 classification, indicating unlimited shelf life and no special moisture control requirements during storage or handling.
