XC6210B12AMR-G Equivalent & Substitute Parts

Part Overview

The XC6210B12AMR-G is a linear voltage regulator IC manufactured by Torex Semiconductor Ltd, classified as a Power Management (PMIC) component. This device delivers a fixed positive output of 1.25V at 500mA with a maximum dropout voltage of 0.4V at 100mA. The regulator features an enable control function and over-current protection, operating across the temperature range of -40°C to 85°C. The component is housed in a SOT-25 surface mount package (SC-74A, SOT-753) and is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified to address component availability, supply chain continuity, and inventory management requirements while maintaining electrical and mechanical compatibility within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the XC6210B12AMR-G are identified based on strict electrical and mechanical parameter matching. The substitution criteria are defined by the following key parameters:

Electrical Compatibility Requirements:

• Fixed output voltage of 1.25V
• Output current capability of 500mA
• Maximum input voltage of 6V
• Dropout voltage specification of 0.4V at 100mA
• PSRR of 60dB at 1kHz
• Enable control function
• Over-current protection feature

Mechanical Compatibility Requirements:

• Surface mount packaging
• SOT-25 package type (SC-74A, SOT-753 case)
• Operating temperature range of -40°C to 85°C

Compliance Requirements:

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

The XC6210A12AMR-G is classified as a parametric equivalent based on matching all electrical output specifications, control features, protection mechanisms, and mechanical packaging requirements. Variations in quiescent current (61.5 µA versus 55 µA) remain within acceptable operational tolerances for this device category and do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6210B12AMR-G and XC6210A12AMR-G are active production components manufactured by Torex Semiconductor Ltd with identical ROHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts is based on availability and inventory status rather than electrical or mechanical performance differences.

The XC6210B12AMR-G is suitable for applications requiring the specified 1.25V fixed output at 500mA with enable control and over-current protection in surface mount SOT-25 packaging. The XC6210A12AMR-G provides an equivalent functional alternative with higher current inventory availability (1276 pieces versus 977 pieces) and a marginally higher quiescent current specification (61.5 µA versus 55 µA) that does not impact circuit performance within standard operating conditions.

Both components meet the same compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN classification) and share identical electrical output specifications, control features, and thermal operating ranges. Direct substitution is supported without circuit redesign or board layout modification.

Frequently Asked Questions (FAQ)

Q: Can the XC6210A12AMR-G be used as a direct replacement for the XC6210B12AMR-G?

A: Yes. Both components deliver identical fixed output voltage (1.25V), output current (500mA), dropout voltage (0.4V @ 100mA), PSRR (60dB at 1kHz), and operate across the same temperature range (-40°C to 85°C). The quiescent current difference (61.5 µA versus 55 µA) is within acceptable operational tolerance for this device category. Both use identical SOT-25 packaging and surface mount configuration.

Q: Are there any differences in control or protection features between these parts?

A: No. Both the XC6210B12AMR-G and XC6210A12AMR-G include identical enable control functionality and over-current protection mechanisms. Functional behavior in circuit applications is equivalent.

Q: Do these parts have the same compliance certifications?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, carry EAR99 ECCN classification, and share identical moisture sensitivity level ratings (MSL 1, Unlimited). They meet the same regulatory and environmental standards.

Q: Is the SOT-25 package identical for both parts?

A: Yes. Both components use the SOT-25 package type with SC-74A and SOT-753 case designations. Pin configuration, footprint, and surface mount requirements are identical, requiring no PCB layout modifications for substitution.

Q: What is the significance of the quiescent current difference?

A: The XC6210A12AMR-G has a quiescent current of 61.5 µA compared to 55 µA for the XC6210B12AMR-G. This 6.5 µA difference represents approximately 12% variation and remains within acceptable tolerance for linear regulator applications. This parameter does not affect substitutability in standard circuit designs.

Q: Can I use either part interchangeably in production?

A: Yes. Both parts are active production components with identical electrical specifications, mechanical packaging, and compliance certifications. Selection can be based on inventory availability and supply chain requirements without affecting circuit performance or reliability.
