Substitute Part Grouping Explanation

Substitution eligibility for the XC6501B3517R-G is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Output voltage (fixed): 3.5V
• Maximum input voltage: 6V
• Output current rating: 200mA
• Package type: 4-XDFN (4-USPN 0.90x1.2)
• Mounting type: Surface Mount
• Control features: Enable function
• Protection features: Over-current protection
• Operating temperature range: -40°C to 85°C
• RoHS3 compliance status
• Moisture sensitivity level: 1 (Unlimited)

Allowable Parameter Variations: Substitute parts may exhibit differences in the following parameters while maintaining functional compatibility:

• Dropout voltage (maximum)
• Quiescent current (Iq)
• PSRR (Power Supply Rejection Ratio)

These variations do not affect direct substitution capability when all mandatory criteria are met.

Engineering Selection Recommendations

XC6215B3527R-G Substitution Eligibility:

The XC6215B3527R-G is a direct parametric equivalent to the XC6501B3517R-G and qualifies as a substitute part. Both devices are manufactured by Torex Semiconductor Ltd and maintain Active product status with identical RoHS3 and REACH compliance certifications.

Compliance & Regulatory Alignment:

• Both parts carry RoHS3 Compliant status
• Both maintain REACH Unaffected designation
• Both are classified under ECCN EAR99
• Both share identical HTSUS code: 8542.39.0001
• Both maintain MSL Level 1 (Unlimited moisture sensitivity)

Functional Compatibility: The XC6215B3527R-G maintains all mandatory electrical and mechanical parameters required for direct substitution. The device delivers the same fixed 3.5V output at 200mA with identical input voltage range (6V maximum) and operating temperature specification (-40°C to 85°C). Both parts feature enable control and over-current protection in the identical 4-USPN surface mount package.

Performance Characteristics: The XC6215B3527R-G exhibits lower quiescent current (1.5 µA versus 21 µA), which may provide improved efficiency in low-power standby conditions. The dropout voltage specification differs at the measurement point (0.42V @ 100mA versus 0.35V @ 200mA), reflecting different test conditions rather than incompatibility.

Frequently Asked Questions (FAQ)

Q: Can the XC6215B3527R-G replace the XC6501B3517R-G in existing designs?

A: Yes. The XC6215B3527R-G is a direct substitute meeting all mandatory electrical and mechanical parameters. Both devices provide 3.5V fixed output at 200mA in the identical 4-USPN package with matching control and protection features.

Q: Are there differences in package dimensions between these parts?

A: No. Both the XC6501B3517R-G and XC6215B3527R-G use the 4-USPN package with dimensions of 0.90x1.2mm. PCB footprints and reflow profiles are identical.

Q: What is the significance of the different quiescent current values?

A: The XC6215B3527R-G operates at 1.5 µA quiescent current compared to 21 µA for the XC6501B3517R-G. This lower standby current consumption may reduce overall system power draw in applications where the regulator remains enabled during low-power modes. This difference does not affect substitution compatibility.

Q: Do both parts require identical external component values?

A: Yes. Both regulators operate with the same input and output voltage specifications (6V maximum input, 3.5V fixed output) and identical current ratings (200mA). External capacitor and resistor values determined for the XC6501B3517R-G remain valid for the XC6215B3527R-G.

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

A: No. Both parts maintain identical RoHS3 compliance, REACH Unaffected status, and MSL Level 1 rating. Regulatory and environmental certifications are equivalent.

Q: What does the dropout voltage specification difference indicate?

A: The XC6501B3517R-G specifies 0.35V dropout at 200mA, while the XC6215B3527R-G specifies 0.42V at 100mA. These measurements occur at different load currents and reflect device characterization at those specific operating points. Both devices maintain adequate headroom for the specified 6V maximum input voltage and 3.5V output requirement.

Q: Can these parts be used interchangeably in production?

A: Yes. Both parts are Active status products from the same manufacturer with identical electrical performance at the specified operating points. Inventory availability and lead time considerations may determine which part is selected for procurement.
