Key Parameters

Substitute Part Grouping Explanation

Substitution of the XC6210C38AMR-G is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Fixed output voltage of 3.85V
• Output current rating of 700mA
• Maximum input voltage of 6V
• Voltage dropout specification of 0.075V @ 100mA
• PSRR of 60dB (1kHz)
• Operating temperature range of -40°C ~ 85°C
• Enable control feature and Over Current protection

Mechanical Equivalence Criteria:

• Surface mount mounting type
• SC-74A, SOT-753 package designation
• SOT-25 supplier device package

Compliance Equivalence Criteria:

• ROHS3 Compliant status
• Moisture Sensitivity Level 1 (Unlimited)
• Active product status

The XC6210B38AMR-G qualifies as a parametric equivalent because it maintains identical electrical specifications across all critical parameters, identical mechanical packaging, and equivalent compliance certifications. The variance in quiescent current (55 µA vs. 69 µA) represents an improvement in power efficiency and does not disqualify substitution compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6210C38AMR-G and XC6210B38AMR-G are active production components manufactured by Torex Semiconductor Ltd with identical ROHS3 compliance and MSL ratings. Selection between these parts should be based on the following engineering considerations:

Primary Selection Criteria:

• Both parts maintain identical electrical performance across all specified parameters
• Both parts are housed in identical SC-74A, SOT-753 packages with SOT-25 supplier designation
