Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XC6210C14AMR-G is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Output voltage (fixed at 1.45V)
• Maximum output current (500mA)
• Maximum input voltage (6V)
• Package type (SOT-25 / SC-74A, SOT-753)
• Output configuration (Positive)
• Output type (Fixed)
• Mounting type (Surface Mount)
• Operating temperature range (-40°C ~ 85°C)

Allowable Variation Parameters:

• Quiescent current (Iq): Minor variations acceptable within the same device family
• PSRR: Specification maintained at 60dB (1kHz)
• Dropout voltage: Maintained at 0.25V @ 100mA

The XC6210B14AMR-G qualifies as a parametric equivalent within the Torex XC6210 base product family, sharing identical electrical specifications and physical packaging while representing a design iteration of the same regulator platform.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6210C14AMR-G and XC6210B14AMR-G are active production devices from Torex Semiconductor Ltd with full ROHS3 compliance and REACH unaffected status. The XC6210B14AMR-G represents a design variant within the same XC6210 base product family with improved quiescent current performance (55 µA versus 61.5 µA), resulting in lower standby power consumption. This improvement does not alter functional compatibility or electrical performance in standard operating conditions.

Selection between these parts should be based on:

1. Supply availability: Both parts maintain active inventory status; current availability is 856 units (XC6210C14AMR-G) and 858 units (XC6210B14AMR-G).

2. Power efficiency requirements: The XC6210B14AMR-G offers superior quiescent current characteristics for battery-powered or low-power standby applications.

3. Regulatory compliance: Both parts satisfy ROHS3 and REACH requirements for regulated markets.

4. Packaging and thermal considerations: Identical SOT-25 packaging ensures direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can XC6210B14AMR-G be used as a direct replacement for XC6210C14AMR-G?

A: Yes. The XC6210B14AMR-G is a parametric equivalent with identical output voltage (1.45V), output current (500mA), input voltage rating (6V), dropout voltage (0.25V @ 100mA), and package type (SOT-25). The only difference is improved quiescent current (55 µA vs. 61.5 µA), which does not affect functional compatibility. No PCB modifications are required.

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

A: No thermal differences exist. Both devices operate across the same temperature range (-40°C ~ 85°C). The XC6210B14AMR-G provides lower standby power consumption due to reduced quiescent current, which may result in marginally lower junction temperature in idle states.

Q: Do both parts require identical PCB layout and component placement?

A: Yes. Both parts use the identical SOT-25 package (SC-74A, SOT-753), requiring no changes to PCB footprints, trace routing, or component placement. Existing designs can accommodate either part without layout modifications.

Q: What is the significance of the "C" and "B" designations in the part numbers?

A: The "C" and "B" designations indicate design revisions within the XC6210 product family. Both are active production variants from Torex Semiconductor Ltd with identical electrical specifications and package types. The revision difference reflects internal design optimization, primarily in quiescent current performance.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both XC6210C14AMR-G and XC6210B14AMR-G are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for sale in restricted markets.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For standard applications, either part is suitable. For battery-powered or low-power standby applications where quiescent current is critical, the XC6210B14AMR-G is preferred due to its 6.5 µA lower Iq specification.
