Key Parameters

Substitute Part Grouping Explanation

Substitution of the XC6210D12AMR-G is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Output voltage (fixed): 1.25V
• Output current rating: 500mA
• Maximum input voltage: 6V
• Dropout voltage specification: 0.4V @ 100mA
• Package type: SOT-25 (SC-74A, SOT-753)
• Mounting type: Surface Mount
• Operating temperature range: -40°C ~ 85°C

Allowable Variation Parameters:

• Quiescent current (Iq): Minor variations within the same device family are acceptable
• PSRR: Specification remains consistent at 60dB (1kHz)

The XC6210A12AMR-G qualifies as a parametric equivalent substitute because it maintains identical electrical specifications for output voltage, output current, input voltage limits, dropout voltage, package configuration, and operating temperature range. The variance in quiescent current (61.5 µA vs. 55 µA) falls within acceptable tolerances for linear regulator substitution within the same manufacturer's product line.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6210D12AMR-G and XC6210A12AMR-G are active production components manufactured by Torex Semiconductor Ltd with full ROHS3 compliance and MSL Level 1 rating. Selection between these parts should be based on:

Inventory Availability: The XC6210A12AMR-G currently has 1276 units in stock compared to 979 units for the XC6210D12AMR-G, providing greater supply assurance.

Regulatory Compliance: Both parts maintain identical ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification, ensuring equivalent regulatory standing for procurement and deployment.

Electrical Performance: The quiescent current difference of 6.5 µA between the two parts is negligible for most applications and does not affect functional equivalence in standard linear regulator circuits.

Package and Mounting: Identical SOT-25 package specifications ensure direct pin-compatible substitution without PCB redesign or layout modification.

Frequently Asked Questions (FAQ)

Q: Can the XC6210A12AMR-G be used as a direct replacement for the XC6210D12AMR-G?

A: Yes. Both parts are pin-compatible with identical SOT-25 packaging, matching output voltage (1.25V), output current (500mA), input voltage limits (6V max), and dropout voltage specifications (0.4V @ 100mA). No circuit modification is required.

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

A: The XC6210D12AMR-G has a quiescent current of 55 µA while the XC6210A12AMR-G has 61.5 µA. This 6.5 µA difference is within acceptable tolerance for linear regulator substitution and has negligible impact on standby power consumption in most applications.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the XC6210D12AMR-G and XC6210A12AMR-G operate across the identical temperature range of -40°C to 85°C (TA), ensuring equivalent thermal performance.

Q: Do these parts have the same regulatory compliance status?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under EAR99 ECCN. They carry identical MSL Level 1 (Unlimited) moisture sensitivity ratings.

Q: Which part should be selected for new designs?

A: Selection should be based on current inventory availability and supply chain requirements. Both parts are active production components with identical electrical and mechanical specifications. The XC6210A12AMR-G offers higher current inventory availability (1276 units vs. 979 units).

Q: Is PCB redesign necessary when substituting between these parts?

A: No. Both parts use the SC-74A SOT-753 (SOT-25) package with identical pin configuration and mounting type (surface mount). Direct substitution is possible without PCB layout changes.
