Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XC6217D18AMR-G is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Fixed output voltage of 1.85V
• Output current rating of 200mA minimum
• Positive output configuration
• Over current protection capability
• Enable control feature
• Operating temperature range of -40°C to 85°C
• Surface mount technology
• RoHS3 compliance and REACH unaffected status

Acceptable Variation Parameters:

• Input voltage maximum (substitute may be lower if ≥ 5.5V)
• Dropout voltage (substitute may be higher if within application tolerance)
• Quiescent current (substitute may be lower)
• Package designation (SOT-23-5 is mechanically compatible with SOT-25 pinout requirements)
• Packaging format (Cut Tape acceptable as alternative to Tape & Reel)

The S-1315A1J-M5T1U3 manufactured by ABLIC Inc. qualifies as a parametric equivalent based on these criteria.

Engineering Selection Recommendations

XC6217D18AMR-G Selection Criteria:

• Primary choice when Torex Semiconductor supply is available
• Preferred for applications requiring maximum input voltage tolerance up to 6V
• Optimal for low-dropout applications requiring 0.21V dropout at 100mA
• Tape & Reel packaging suitable for high-volume automated assembly

S-1315A1J-M5T1U3 Selection Criteria:

• Suitable substitute when Torex supply is constrained
• Acceptable for applications with input voltage maximum of 5.5V or lower
• Advantageous for battery-powered or ultra-low-power applications due to 1µA quiescent current
• Cut Tape packaging appropriate for lower-volume or manual assembly operations
• Both parts maintain identical RoHS3 and REACH compliance status
• Both parts operate across the full -40°C to 85°C temperature range
• Both parts provide identical output voltage and current specifications

Selection between these parts should be based on supply availability, input voltage requirements, and packaging format needs. No performance degradation occurs in applications where input voltage does not exceed 5.5V and dropout voltage specification of 0.486V is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the S-1315A1J-M5T1U3 directly replace the XC6217D18AMR-G in all applications?

A: The S-1315A1J-M5T1U3 is a parametric equivalent for applications where the input voltage does not exceed 5.5V and the higher dropout voltage of 0.486V @ 200mA is acceptable. If your application requires the full 6V input voltage range or the lower 0.21V dropout specification, the XC6217D18AMR-G is the required choice.

Q: Are the package dimensions identical between SOT-25 and SOT-23-5?

A: Both parts use the SC-74A package designation, which provides mechanical compatibility for PCB footprint and soldering operations. Verify your PCB layout accommodates the specific pin configuration of your selected part.

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

A: The XC6217D18AMR-G draws 8µA quiescent current, while the S-1315A1J-M5T1U3 draws 1µA. For battery-powered applications, the lower quiescent current of the ABLIC part provides extended operating time.

Q: Do both parts support the Enable control feature?

A: Yes, both the XC6217D18AMR-G and S-1315A1J-M5T1U3 include Enable control functionality and over current protection.

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

A: Both parts are RoHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. No compliance differences exist.

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

A: The XC6217D18AMR-G has a dropout voltage of 0.21V @ 100mA, while the S-1315A1J-M5T1U3 has 0.486V @ 200mA. Lower dropout voltage allows operation with lower input voltages. Verify your application's minimum input voltage requirement against the selected part's dropout specification.

Q: Can I use either part interchangeably in my design?

A: Interchangeability depends on your specific application requirements. Both parts provide identical 1.85V output at 200mA with identical temperature range and protection features. Differences in input voltage tolerance and dropout voltage must be evaluated against your circuit design specifications.
