Substitute Part Grouping Explanation

Substitute parts for the XC6210A38AMR-G are identified based on strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

Fixed output voltage of 3.85V
Output current capacity of 700mA
Maximum input voltage of 6V
Dropout voltage specification of 0.075V at 100mA
PSRR of 60dB at 1kHz
Operating temperature range of -40°C to 85°C

Mechanical Equivalence Criteria:

SOT-25 package configuration (SC-74A, SOT-753)
Surface mount mounting type
Identical control features (Enable function)
Identical protection features (Over Current protection)

Compliance Equivalence Criteria:

ROHS3 compliance status
Moisture Sensitivity Level 1 (Unlimited)

Engineering Selection Recommendations

Both the XC6210A38AMR-G and XC6210B38AMR-G are active production components with identical ROHS3 compliance and REACH unaffected status. Selection between these parts is based on the following engineering considerations:

Primary Selection Criteria: The XC6210A38AMR-G and XC6210B38AMR-G are functionally interchangeable for applications requiring a 3.85V, 700mA linear regulator in SOT-25 packaging. Both components maintain equivalent electrical performance across all critical parameters including output voltage, output current, dropout voltage, PSRR, and operating temperature range.

Quiescent Current Consideration: The XC6210B38AMR-G exhibits lower quiescent current (55 µA) compared to the XC6210A38AMR-G (69 µA). This 14 µA difference may be relevant for battery-powered or ultra-low-power applications where standby current consumption is a design constraint.

Availability and Supply Chain: Component selection may be influenced by inventory availability. The XC6210A38AMR-G currently maintains 1002 pieces in stock, while the XC6210B38AMR-G maintains 853 pieces in stock.

Compliance and Regulatory: Both parts satisfy ROHS3 compliance requirements and carry REACH unaffected status, making either suitable for applications subject to environmental and regulatory restrictions.

Frequently Asked Questions (FAQ)

Q: Can the XC6210B38AMR-G be used as a direct replacement for the XC6210A38AMR-G?

A: Yes. The XC6210B38AMR-G is a parametric equivalent substitute. Both components deliver identical output voltage (3.85V), output current (700mA), dropout voltage (0.075V @ 100mA), and operate across the same temperature range (-40°C to 85°C). Both are housed in SOT-25 packaging and feature identical control and protection functions.

Q: What is the difference between these two parts?

A: The primary difference is quiescent current. The XC6210B38AMR-G operates at 55 µA, while the XC6210A38AMR-G operates at 69 µA. This 14 µA variation does not affect functional equivalence for standard applications but may be significant in ultra-low-power designs where standby current is critical.

Q: Are both parts available in the same package?

A: Yes. Both the XC6210A38AMR-G and XC6210B38AMR-G are supplied in SOT-25 packaging (SC-74A, SOT-753) as surface mount components. Pin configuration and footprint are identical.

Q: Do both parts have the same compliance certifications?

A: Yes. Both components are ROHS3 compliant, carry REACH unaffected status, and maintain Moisture Sensitivity Level 1 (Unlimited). Both are active production parts suitable for applications subject to environmental regulations.

Q: Which part should I select for a battery-powered application?

A: For battery-powered applications where quiescent current is a design consideration, the XC6210B38AMR-G is the appropriate selection due to its lower standby current (55 µA versus 69 µA). For applications where quiescent current is not a constraint, either part is suitable.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts maintain identical PSRR (60dB at 1kHz), dropout voltage (0.075V @ 100mA), and operating temperature range (-40°C to 85°C). Thermal performance and noise characteristics are equivalent.

Q: Can I mix these parts in the same production run?

A: Yes. Both parts are functionally equivalent and pin-compatible. However, design documentation should specify the acceptable part numbers to ensure consistency with supply chain and quality control procedures.
