Substitute Part Grouping Explanation

Substitution eligibility for the XC6210B252PR-G is determined by strict parametric equivalence within the XC6210 series family. The substitute part XC6210A252PR-G qualifies as a parametric equivalent based on the following critical parameters:

Identical Parameters (Substitution Criteria):

• Output voltage configuration: Positive fixed 2.5V
• Output current rating: 700mA
• Maximum input voltage: 6V
• Dropout voltage specification: 0.09V @ 100mA
• Package type: SOT-89-5/6 (Surface Mount)
• Control features: Enable function
• Protection features: Over Current protection
• Operating temperature range: -40°C to 85°C
• Compliance certifications: ROHS3, REACH Unaffected, EAR99

Allowable Parameter Variance:

• Quiescent current (Iq): XC6210B252PR-G = 55µA; XC6210A252PR-G = 66µA (variance within acceptable tolerance for this device class)
• PSRR: Both rated at 60dB (1kHz)

Both parts share the same base product number (XC6210) and are manufactured by the same supplier, confirming their functional equivalence within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (XC6210B252PR-G): The XC6210B252PR-G is the recommended primary choice based on superior inventory availability (1169 units) and lower quiescent current specification (55µA). This part maintains active production status and full ROHS3 compliance, ensuring long-term supply reliability and regulatory conformance for applications requiring 2.5V/700mA regulation.

Alternative Selection (XC6210A252PR-G): The XC6210A252PR-G serves as a direct parametric equivalent for applications where primary inventory is unavailable. With 898 units in stock, this substitute maintains identical electrical performance across all critical parameters including output voltage, current rating, dropout voltage, and package configuration. The 11µA increase in quiescent current (66µA vs. 55µA) remains within acceptable tolerance for this device class and does not impact functional compatibility in standard applications.

Compliance & Certification: Both parts carry identical regulatory certifications: ROHS3 Compliant, REACH Unaffected status, and EAR99 classification. Both are classified as Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Substitution Validity: Direct substitution between XC6210B252PR-G and XC6210A252PR-G is valid for all applications requiring positive fixed 2.5V output at 700mA with SOT-89-5/6 surface mount packaging. No circuit modifications, PCB layout changes, or thermal management adjustments are required when switching between these parts.

Frequently Asked Questions (FAQ)

Q: Can XC6210A252PR-G be used as a direct replacement for XC6210B252PR-G in production?

A: Yes. Both parts are parametric equivalents within the XC6210 series. They share identical output voltage (2.5V), output current (700mA), input voltage rating (6V max), dropout voltage (0.09V @ 100mA), package type (SOT-89-5/6), and operating temperature range (-40°C to 85°C). The quiescent current difference (55µA vs. 66µA) is within acceptable tolerance and does not affect circuit functionality.

Q: Are there any PCB layout or thermal considerations when substituting between these parts?

A: No. Both parts use identical SOT-89-5/6 surface mount packaging with the same pinout and thermal characteristics. PCB layout, trace routing, and thermal management designs require no modification when switching between XC6210B252PR-G and XC6210A252PR-G.

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

A: The XC6210B252PR-G specifies 55µA quiescent current while the XC6210A252PR-G specifies 66µA. This 11µA difference represents approximately 20% variance in standby power consumption. For applications with strict power budget constraints, the XC6210B252PR-G offers marginally lower standby current. However, both values are typical for this device class and do not impact functional compatibility.

Q: Do both parts require the same external component values (capacitors, resistors)?

A: Yes. Both parts are functionally equivalent and require identical external component specifications. Reference designs, bill of materials, and circuit schematics developed for XC6210B252PR-G apply directly to XC6210A252PR-G without modification.

Q: Are there supply chain or lead time differences between these parts?

A: Current inventory shows XC6210B252PR-G at 1169 units and XC6210A252PR-G at 898 units, both in new original stock. Availability may vary based on procurement timing and supplier allocation. Both parts maintain active production status with Torex Semiconductor Ltd.

Q: What compliance certifications apply to both substitute parts?

A: Both XC6210B252PR-G and XC6210A252PR-G carry identical certifications: ROHS3 Compliant, REACH Unaffected, EAR99 classification, and Moisture Sensitivity Level 1 (Unlimited). Both parts meet the same regulatory and environmental standards for industrial and commercial applications.

Q: Can these parts be used interchangeably in existing designs without re-qualification?

A: Yes. The parametric equivalence of these parts within the XC6210 series, combined with identical packaging and compliance certifications, permits direct substitution without design re-qualification, circuit simulation, or functional testing in applications where the original part was qualified.
