Substitute Part Grouping Explanation

Substitution of the XC6210A19AMR-G is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Output voltage (fixed): 1.95V
• Output current capability: 700mA
• Maximum input voltage: 6V
• Maximum dropout voltage: 0.135V @ 100mA
• Package type: SOT-25 (SC-74A, SOT-753)
• Output configuration: Positive
• Number of regulators: 1
• Control features: Enable
• Protection features: Over Current
• Operating temperature range: -40°C ~ 85°C (TA)
• Mounting type: Surface Mount
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation Parameters:

• Quiescent current (Iq): Variations permitted within design margin
• PSRR: Variations permitted within design margin

The XC6210B19AMR-G qualifies as a parametric equivalent based on identical output voltage, current rating, input voltage specification, dropout voltage, package configuration, and all compliance certifications. Variations in quiescent current and PSRR do not affect functional substitution for standard linear regulator applications.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6210A19AMR-G and XC6210B19AMR-G are active production parts from Torex Semiconductor Ltd with identical electrical specifications for output voltage, current capacity, input voltage rating, and dropout voltage performance. Both devices are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity classification, indicating equivalent environmental handling and storage requirements.

The XC6210B19AMR-G exhibits lower quiescent current consumption (55 µA versus 63 µA), which may provide marginal power efficiency benefits in battery-powered or low-power standby applications. This difference does not affect functional compatibility or circuit operation in standard linear regulator topologies.

Selection between these parts should be based on availability, lead time, and inventory status. Both parts are suitable for direct substitution in applications requiring a 1.95V, 700mA positive linear voltage regulator with SOT-25 surface mount packaging.

Frequently Asked Questions (FAQ)

Q: Can the XC6210B19AMR-G be used as a direct replacement for the XC6210A19AMR-G?

A: Yes. Both parts share identical output voltage (1.95V), output current (700mA), input voltage rating (6V maximum), dropout voltage (0.135V @ 100mA), package type (SOT-25), and all control and protection features. The parts are pin-compatible and functionally equivalent for circuit applications.

Q: What is the difference between the XC6210A19AMR-G and XC6210B19AMR-G?

A: The primary difference is quiescent current specification. The XC6210A19AMR-G draws 63 µA, while the XC6210B19AMR-G draws 55 µA. Both devices maintain identical output voltage regulation, current capacity, and thermal performance across the -40°C to 85°C operating range.

Q: Are both parts available in the same package?

A: Yes. Both the XC6210A19AMR-G and XC6210B19AMR-G are supplied in SOT-25 packaging (SC-74A, SOT-753 case designation) with surface mount configuration. PCB layout and footprint requirements are identical.

Q: Do these parts have the same compliance certifications?

A: Yes. Both parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity level, and are REACH unaffected. Compliance documentation and environmental handling requirements are equivalent.

Q: Which part should I select for a new design?

A: Selection should be based on current availability and supply chain lead times. From an engineering perspective, both parts are functionally equivalent. The XC6210B19AMR-G may be preferred in applications where minimizing quiescent current consumption is a design objective.

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

A: Yes. Both parts are functionally interchangeable and carry identical electrical specifications for all critical parameters. Mixing is acceptable provided the application does not impose specific quiescent current constraints that would differentiate performance.

Q: What is the maximum input voltage for both parts?

A: Both the XC6210A19AMR-G and XC6210B19AMR-G accept a maximum input voltage of 6V. Input voltage must not exceed this rating to prevent device damage.

Q: Are there any temperature-related performance differences?

A: No. Both parts operate across the identical temperature range of -40°C to 85°C (TA) with equivalent thermal performance and dropout voltage characteristics across this range.
