XC6210B19AMR-G Equivalent & Substitute Parts

Part Overview

The XC6210B19AMR-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 1.95V at 700mA with a maximum dropout voltage of 0.135V @ 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 an SC-74A (SOT-753) surface-mount package and is supplied in Tape & Reel format. The XC6210B19AMR-G maintains Active product status and holds ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). Equivalent substitute parts are identified based on matching electrical specifications, output configuration, and mechanical packaging requirements.

Substitute Part Grouping Explanation

Substitute parts for the XC6210B19AMR-G are identified through parametric equivalence matching. The substitution logic is based on the following critical parameters that must remain constant across all equivalent devices:

• Output Voltage (Fixed): 1.95V
• Output Current Capability: 700mA
• Maximum Input Voltage: 6V
• Package Type: SC-74A (SOT-753) / SOT-25
• Output Configuration: Positive Fixed
• Control Features: Enable function
• Protection Features: Over-current protection
• Operating Temperature Range: -40°C to 85°C
• Compliance Status: ROHS3 Compliant, REACH Unaffected

The XC6210A19AMR-G qualifies as a parametric equivalent substitute based on matching all critical electrical and mechanical specifications. Minor variations in quiescent current (Iq) do not disqualify substitution when all primary functional parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6210B19AMR-G and XC6210A19AMR-G maintain Active product status with full ROHS3 compliance and REACH unaffected designation. Selection between these parts is based on application-specific requirements and inventory availability.

The XC6210B19AMR-G exhibits a quiescent current of 55 µA, making it suitable for applications where standby power consumption is a critical design parameter. The XC6210A19AMR-G operates at 63 µA quiescent current, representing an 8 µA differential. This variance is negligible in most applications but becomes significant in battery-powered or ultra-low-power designs where cumulative standby current directly impacts system runtime.

Both devices deliver identical output voltage regulation (1.95V fixed), maximum output current (700mA), dropout voltage performance (0.135V @ 100mA), and PSRR characteristics (60dB @ 1kHz). The mechanical packaging, thermal operating range, and protection features remain identical across both variants. Selection should prioritize the part with confirmed availability and lead time alignment with project schedules.

Frequently Asked Questions (FAQ)

Q: Can the XC6210A19AMR-G directly replace the XC6210B19AMR-G in existing designs?

A: Yes. Both parts share identical output voltage (1.95V), output current capability (700mA), maximum input voltage (6V), package type (SOT-25), and operating temperature range (-40°C to 85°C). The 8 µA difference in quiescent current does not affect functional compatibility in standard applications.

Q: What is the significance of the quiescent current difference between these parts?

A: The XC6210B19AMR-G operates at 55 µA quiescent current while the XC6210A19AMR-G operates at 63 µA. In applications with continuous operation or high-frequency switching, this difference is negligible. In battery-powered or standby-mode applications, the lower quiescent current of the XC6210B19AMR-G may extend system runtime by reducing parasitic power draw.

Q: Are both parts available in the same packaging format?

A: Yes. Both the XC6210B19AMR-G and XC6210A19AMR-G are supplied in SC-74A (SOT-753) surface-mount packages with SOT-25 supplier device packaging. They are compatible with identical PCB layouts and reflow soldering processes.

Q: Do these parts require different circuit design considerations?

A: No. Both devices feature identical enable control functionality, over-current protection, dropout voltage performance, and PSRR characteristics. Circuit design, decoupling requirements, and application schematics remain unchanged between the two variants.

Q: What compliance certifications apply to both substitute parts?

A: Both the XC6210B19AMR-G and XC6210A19AMR-G hold ROHS3 compliance and REACH unaffected status. Moisture sensitivity level is rated at MSL 1 (unlimited) for both devices, indicating no moisture-related handling restrictions during storage or assembly.

Q: Is there a preferred part for new design implementations?

A: Selection between these parts depends on application requirements and inventory status. For designs prioritizing minimal standby power consumption, the XC6210B19AMR-G (55 µA Iq) is appropriate. For general-purpose applications without specific quiescent current constraints, either part is functionally equivalent. Consult current inventory availability and lead time data to optimize procurement timing.
