Substitute Part Grouping Explanation

Substitution of the XC6501C3517R-G is determined by strict alignment of the following critical parameters:

Mechanical Compatibility:

• Identical package type: 4-XDFN
• Identical supplier device package: 4-USPN (0.90x1.2)
• Identical mounting type: Surface Mount

Electrical Compatibility:

• Identical output configuration: Positive
• Identical output type: Fixed
• Identical fixed output voltage: 3.5V
• Identical maximum input voltage: 6V
• Identical output current rating: 200mA
• Identical control features: Enable function
• Identical protection features: Over Current protection
• Identical operating temperature range: -40°C ~ 85°C (TA)

Regulatory and Compliance Alignment:

• Identical RoHS status: ROHS3 Compliant
• Identical MSL rating: 1 (Unlimited)
• Identical REACH status: REACH Unaffected

Substitute parts must satisfy all mechanical and electrical parameters listed above. Variations in quiescent current, dropout voltage, or PSRR do not disqualify substitution when all primary parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the XC6501C3517R-G and XC6215B3527R-G are active production components from Torex Semiconductor Ltd with identical mechanical packaging and core electrical specifications. Both devices are ROHS3 compliant and carry MSL 1 ratings, indicating equivalent environmental and regulatory standing.

The XC6501C3517R-G features a lower maximum dropout voltage of 0.35V at 200mA and provides specified PSRR performance of 50dB at 1kHz. The XC6215B3527R-G offers significantly lower quiescent current consumption at 1.5 µA compared to 21 µA, making it suitable for applications prioritizing standby power efficiency.

Selection between these parts depends on application-specific requirements: choose the XC6501C3517R-G when dropout voltage performance and PSRR specification are critical; select the XC6215B3527R-G when minimizing quiescent current draw is the primary design objective. Both parts are electrically and mechanically interchangeable within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can the XC6215B3527R-G directly replace the XC6501C3517R-G in existing designs?

A: Yes. Both devices share identical package geometry (4-USPN 0.90x1.2), output voltage (3.5V fixed), output current rating (200mA), input voltage maximum (6V), control features (Enable), protection features (Over Current), and operating temperature range (-40°C to 85°C). Pin-to-pin compatibility is maintained.

Q: What are the differences between these two parts?

A: The XC6501C3517R-G has a maximum dropout voltage of 0.35V at 200mA and quiescent current of 21 µA with specified PSRR of 50dB at 1kHz. The XC6215B3527R-G has a maximum dropout voltage of 0.42V at 100mA and significantly lower quiescent current of 1.5 µA. PSRR is not specified for the XC6215B3527R-G.

Q: Which part should I select for low-power applications?

A: The XC6215B3527R-G is preferable for applications requiring minimal standby power consumption due to its 1.5 µA quiescent current, compared to 21 µA in the XC6501C3517R-G.

Q: Are both parts available in the same packaging?

A: Yes. Both the XC6501C3517R-G and XC6215B3527R-G are supplied in 4-USPN (0.90x1.2) surface mount packages with identical mechanical dimensions and pin configurations.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, carry MSL 1 ratings (unlimited moisture sensitivity), and are REACH unaffected. Both are currently in active production status.

Q: What is the significance of the dropout voltage difference?

A: The XC6501C3517R-G specifies 0.35V dropout at 200mA, while the XC6215B3527R-G specifies 0.42V dropout at 100mA. Applications operating at full 200mA output current with tight input voltage margins should evaluate dropout performance requirements against the available input voltage headroom.

Q: Can I use either part interchangeably in my PCB layout?

A: Yes. Both parts use identical 4-XDFN package geometry and 4-USPN supplier package dimensions. PCB footprints, land patterns, and assembly processes remain unchanged between the two parts.
