Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the XC6210D19AMR-G are identified based on strict parametric equivalence within the XC6210 series. All substitute candidates share identical electrical specifications across the following critical parameters: fixed output voltage of 1.95V, maximum input voltage of 6V, output current rating of 700mA, maximum dropout voltage of 0.135V @ 100mA, PSRR of 60dB at 1kHz, enable control feature, over-current protection, SOT-25 package configuration, and operating temperature range of -40°C to 85°C.

The substitution logic is based on the following key parameters that determine functional interchangeability:

• Output voltage specification (1.95V fixed)
• Maximum output current (700mA)
• Package type (SOT-25 / SC-74A)
• Dropout voltage performance (0.135V @ 100mA)
• Control and protection features (Enable, Over Current)
• Compliance certifications (ROHS3, REACH Unaffected)

Variations in quiescent current (Iq) between part variants do not affect substitution eligibility, as this parameter represents a secondary performance characteristic that does not impact the primary voltage regulation function or pin compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—XC6210D19AMR-G, XC6210A19AMR-G, and XC6210B19AMR-G—are active production components with ROHS3 compliance and REACH unaffected status, making them suitable for applications requiring regulatory compliance in consumer and industrial electronics.

Selection between these equivalents should be based on inventory availability and application-specific quiescent current requirements. The XC6210D19AMR-G and XC6210B19AMR-G both feature 55 µA quiescent current, while the XC6210A19AMR-G operates at 63 µA. For battery-powered or ultra-low-power applications where standby current is critical, the 55 µA variants are preferred. For general-purpose voltage regulation applications where quiescent current is not a limiting factor, all three parts are functionally equivalent.

All parts maintain identical electrical performance in voltage regulation, dropout characteristics, and protection features. Pin compatibility and PCB layout requirements are identical across all three variants due to shared SOT-25 packaging.

Frequently Asked Questions (FAQ)

Q: Can XC6210A19AMR-G replace XC6210D19AMR-G in an existing design?

A: Yes. Both parts share identical output voltage (1.95V), output current (700mA), dropout voltage (0.135V @ 100mA), package type (SOT-25), and control/protection features. The only difference is quiescent current (63 µA vs. 55 µA). If the design does not have strict standby current constraints, substitution is direct with no circuit modifications required.

Q: What is the difference between XC6210D19AMR-G and XC6210B19AMR-G?

A: These parts are electrically identical. Both feature 55 µA quiescent current and identical voltage regulation specifications. The difference is internal die revision or manufacturing process generation within the XC6210 series. Both are pin-compatible and functionally interchangeable.

Q: Are all three parts available in the same package?

A: Yes. All three parts use the SC-74A / SOT-753 package designation with SOT-25 supplier device package. They are surface mount components with identical pin configurations and PCB footprints.

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

A: Selection should be based on current inventory levels and application requirements. For designs where quiescent current is a design constraint, select XC6210D19AMR-G or XC6210B19AMR-G (55 µA). For general applications, any of the three parts are suitable. Verify current stock levels with your supplier before finalizing part selection.

Q: Do these parts require different PCB layouts or design considerations?

A: No. All three parts are pin-for-pin compatible with identical electrical specifications for voltage regulation, dropout performance, and protection features. Existing PCB designs and circuit layouts require no modification when substituting between these parts.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts carry identical ROHS3 compliance, REACH unaffected status, MSL rating of 1 (Unlimited), and active production status. They meet the same regulatory requirements for consumer and industrial applications.
