Substitute Part Grouping Explanation

Substitution eligibility for the XC6501C26AMR-G is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Output voltage: 2.65V fixed
• Output current capability: 200mA minimum
• Maximum input voltage: 6V
• Package type: SOT-25 (SC-74A, SOT-753)
• Output configuration: Positive
• Output type: Fixed (single output)
• Control features: Enable function
• Protection features: Over Current protection
• Operating temperature range: -40°C to 85°C minimum
• Mounting type: Surface Mount

Allowable Variation Parameters:

• Voltage dropout: May be lower than 0.38V @ 200mA (improved performance)
• Quiescent current (Iq): May be lower than 20µA (improved efficiency)
• PSRR: May be higher than 50dB @ 1kHz (improved noise rejection)

The XC6217B26AMR-G qualifies as a parametric equivalent substitute based on identical output voltage, output current, input voltage rating, package configuration, and control/protection features. This substitute demonstrates improved electrical performance in dropout voltage, quiescent current, and PSRR specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6501C26AMR-G and XC6217B26AMR-G are active products manufactured by Torex Semiconductor Ltd with identical RoHS3 compliance and REACH unaffected status. Both devices carry MSL Level 1 (Unlimited) moisture sensitivity classification, indicating no special moisture handling requirements during storage or assembly.

The XC6501C26AMR-G remains the primary selection when current inventory availability (1111 units) supports project timelines and when the specified electrical performance characteristics meet application requirements.

The XC6217B26AMR-G functions as a direct substitute when inventory of the primary part is constrained (783 units available). This substitute provides superior electrical performance across three key metrics: reduced dropout voltage (0.17V @ 100mA versus 0.38V @ 200mA), lower quiescent current consumption (8µA versus 20µA), and improved power supply rejection ratio (70dB versus 50dB at 1kHz). These improvements result in reduced thermal dissipation and enhanced noise immunity in the application circuit.

Both parts maintain identical functional compatibility: positive fixed output configuration, 200mA output current capability, 2.65V output voltage, 6V maximum input voltage, SOT-25 package, Enable control feature, and Over Current protection.

Frequently Asked Questions (FAQ)

Q: Can the XC6217B26AMR-G directly replace the XC6501C26AMR-G in existing PCB designs?

A: Yes. Both devices use identical SOT-25 (SC-74A, SOT-753) packaging with the same pinout configuration. No PCB layout modifications are required. The substitute part maintains identical output voltage (2.65V), output current rating (200mA), input voltage rating (6V), and control/protection features.

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

A: The XC6217B26AMR-G demonstrates improved performance in three electrical parameters: dropout voltage is reduced from 0.38V to 0.17V, quiescent current is reduced from 20µA to 8µA, and PSRR is increased from 50dB to 70dB. These improvements reduce power dissipation and enhance noise rejection. Functional operation and package configuration remain identical.

Q: Are both parts compliant with environmental and regulatory requirements?

A: Yes. Both the XC6501C26AMR-G and XC6217B26AMR-G are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity classification. Both are classified under ECCN EAR99 and HTSUS 8542.39.0001.

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

A: Both parts operate across the identical temperature range of -40°C to 85°C (TA), suitable for industrial and commercial applications.

Q: Do both parts include the same control and protection features?

A: Yes. Both devices include Enable control functionality and Over Current protection features, providing identical circuit control and safety characteristics.

Q: Which part should be selected for new designs?

A: Selection depends on availability and performance requirements. The XC6501C26AMR-G is appropriate when current inventory supports project timelines. The XC6217B26AMR-G is appropriate when improved efficiency (lower quiescent current), reduced thermal dissipation (lower dropout voltage), or enhanced noise immunity (higher PSRR) align with application specifications.
