Substitute Part Grouping Explanation

Substitute parts for the XC6505B501PR-G are identified through parametric equivalence matching. The substitution logic is based on the following critical parameters that must remain identical across all equivalent devices:

Electrical Specifications:

• Fixed output voltage of 5V
• Output current rating of 200mA
• Maximum input voltage of 10.5V
• Dropout voltage of 0.185V @ 100mA
• Quiescent current of 8 µA
• PSRR of 50dB (1kHz)

Mechanical and Package Specifications:

• Surface-mount packaging in SOT-89-5 configuration
• Identical pin count and footprint compatibility

Functional Features:

• Enable control capability
• Over-current and over-temperature protection

Compliance and Certification:

• ROHS3 compliance
• Moisture Sensitivity Level 1
• REACH Unaffected status

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The XC6505A501PR-G is a direct parametric equivalent to the XC6505B501PR-G. Both devices are manufactured by Torex Semiconductor Ltd and maintain identical electrical, mechanical, and functional specifications. Both parts carry Active product status and meet ROHS3 compliance requirements with REACH Unaffected designation.

Selection between these parts should be based on availability and supply chain requirements. The XC6505A501PR-G currently maintains higher inventory levels (3300 units) compared to the XC6505B501PR-G (713 units), which may influence procurement decisions for high-volume applications or extended lead-time mitigation strategies.

Both parts are suitable for direct substitution in existing circuit designs without modification to PCB layout, schematic connections, or application firmware, provided the SOT-89-5 package footprint is maintained.
