XC6210B27AMR-G Equivalent & Substitute Parts

Part Overview

The XC6210B27AMR-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 2.75V at 700mA with a maximum dropout voltage of 0.09V @ 100mA, housed in a SOT-25 surface mount package. The regulator features an enable control function and over-current protection, operating across the temperature range of -40°C to 85°C. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent substitute parts are identified based on matching electrical specifications and mechanical compatibility within the linear regulator category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the XC6210B27AMR-G are identified through parametric equivalence within the linear voltage regulator category. The substitution logic is based on the following critical parameters that must remain constant across all equivalent devices:

Fixed Electrical Parameters:

• Output voltage: 2.75V (fixed)
• Output current capability: 700mA
• Maximum input voltage: 6V
• Dropout voltage: 0.09V @ 100mA
• Output configuration: Positive
• Output type: Fixed (single output)
• Control features: Enable function
• Protection features: Over-current protection

Fixed Mechanical Parameters:

• Package type: SOT-25 (SC-74A, SOT-753)
• Mounting type: Surface mount
• Tape & Reel packaging

Fixed Compliance Parameters:

• RoHS3 compliance
• MSL 1 rating
• Active product status

Substitute parts may exhibit variation in quiescent current (Iq) and PSRR specifications within acceptable engineering tolerances, provided all other parameters remain identical. The XC6210 base product number identifies the device family, with letter designations (A, B) indicating minor internal revisions that do not affect functional equivalence for standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6210B27AMR-G and XC6210A27AMR-G maintain Active product status with identical RoHS3 compliance and MSL 1 ratings, confirming long-term availability and environmental regulatory alignment. The devices are functionally equivalent for applications requiring a 2.75V, 700mA linear regulator in SOT-25 packaging.

The primary distinction between these parts is the quiescent current specification: the XC6210B27AMR-G operates at 55 µA, while the XC6210A27AMR-G operates at 66 µA. This 11 µA difference is negligible in applications where quiescent current is not a critical design constraint. For battery-powered or ultra-low-power applications where standby current consumption is a primary design consideration, the XC6210B27AMR-G offers superior performance.

Both parts are manufactured by Torex Semiconductor Ltd and share identical electrical performance in dropout voltage, output current, input voltage rating, and protection features. Pin-to-pin compatibility and functional equivalence are confirmed across all control and protection mechanisms.

Frequently Asked Questions (FAQ)

Q: Can the XC6210A27AMR-G be used as a direct replacement for the XC6210B27AMR-G?

A: Yes. Both parts are functionally equivalent linear voltage regulators with identical output voltage (2.75V), output current (700mA), dropout voltage (0.09V @ 100mA), package type (SOT-25), and control/protection features. The quiescent current difference (66 µA vs. 55 µA) does not affect functional compatibility in standard applications.

Q: What is the significance of the letter designation (A vs. B) in the part number?

A: The letter designation indicates an internal revision level within the XC6210 base product family. Both A and B revisions are Active products from Torex Semiconductor Ltd with identical electrical specifications and mechanical compatibility. The revision does not affect pin configuration, package type, or functional operation.

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

A: Yes. Both the XC6210B27AMR-G and XC6210A27AMR-G are supplied in Tape & Reel (TR) format with SOT-25 packaging (SC-74A, SOT-753 case designation). They are directly interchangeable from a mechanical and assembly perspective.

Q: Which part should be selected for low-power applications?

A: The XC6210B27AMR-G is the preferred choice for applications where quiescent current minimization is important, as it operates at 55 µA compared to 66 µA for the XC6210A27AMR-G. This 11 µA difference becomes significant in battery-powered or always-on standby scenarios.

Q: Are both parts RoHS compliant?

A: Yes. Both the XC6210B27AMR-G and XC6210A27AMR-G are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity) ratings, confirming compliance with current environmental and regulatory standards.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. Both parts share identical pin configurations, package dimensions (SOT-25), and electrical specifications for voltage output, current delivery, and protection features. No PCB redesign or layout modification is required for substitution.
