Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the XC6217C18AMR-G are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Critical Matching Parameters:

• Fixed output voltage of 1.85V
• Output current capability of 200mA
• Operating temperature range of -40°C to 85°C
• Enable control feature and over-current protection
• Surface mount technology with compatible package footprint (SOT-23-5 or SOT-25)
• RoHS3 compliance and REACH unaffected status

Allowable Variations:

• Input voltage maximum may differ (6V vs 5.5V) provided the application input does not exceed the substitute part's rating
• Dropout voltage may vary; the substitute must not exceed application requirements
• Quiescent current and supply current may differ; lower values are acceptable
• PSRR may vary; lower values are acceptable if not critical to application
• Packaging format may differ between tape & reel and cut tape

The S-1315A1J-M5T1U3 manufactured by ABLIC Inc. meets all critical electrical parameters and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (XC6217C18AMR-G): The XC6217C18AMR-G is recommended as the primary choice when the application requires the lowest dropout voltage (0.21V @ 100mA), superior power supply rejection ratio (70dB), and maximum input voltage tolerance (6V). This part is active in production with adequate inventory (691 units). The device is RoHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and consumer applications.

Substitute Part Selection (S-1315A1J-M5T1U3): The S-1315A1J-M5T1U3 is suitable as a substitute when:

• Application input voltage does not exceed 5.5V
• Higher dropout voltage (0.486V @ 200mA) is acceptable within system design margins
• Lower quiescent current (1µA vs 8µA) provides design advantage for battery-powered applications
• Cut tape packaging is acceptable for manufacturing processes
• ABLIC sourcing is preferred or Torex supply is unavailable

Both parts maintain identical output voltage (1.85V), output current (200mA), operating temperature range (-40 to 85°C), control features (Enable), and protection features (Over Current). Both are RoHS3 compliant and REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can the S-1315A1J-M5T1U3 be used as a direct replacement for the XC6217C18AMR-G?

A: The S-1315A1J-M5T1U3 is electrically compatible for applications where the input voltage does not exceed 5.5V and the higher dropout voltage (0.486V @ 200mA) does not violate system headroom requirements. The footprint is compatible (both SOT-23-5 package family). Verify these two parameters before substitution.

Q: What is the primary difference between these two parts?

A: The main differences are input voltage maximum (6V vs 5.5V), dropout voltage (0.21V vs 0.486V @ 200mA), and quiescent current (8µA vs 1µA). The XC6217C18AMR-G offers better performance in high-input-voltage and low-dropout applications, while the S-1315A1J-M5T1U3 excels in low-power standby scenarios.

Q: Are the packages interchangeable?

A: Both parts use SOT-23-5 package family (SC-74A, SOT-753 designation). The footprint is mechanically and electrically compatible. The primary difference is packaging format: XC6217C18AMR-G is supplied in tape & reel, while S-1315A1J-M5T1U3 is supplied in cut tape.

Q: What compliance certifications apply to both parts?

A: Both the XC6217C18AMR-G and S-1315A1J-M5T1U3 are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001. Both have moisture sensitivity level 1 (unlimited shelf life).

Q: Which part should I select for a battery-powered application?

A: The S-1315A1J-M5T1U3 is preferred for battery-powered designs due to significantly lower quiescent current (1µA vs 8µA), reducing standby power consumption. Verify that your input voltage does not exceed 5.5V before selection.

Q: What happens if my application input voltage exceeds 5.5V?

A: The S-1315A1J-M5T1U3 cannot be used if input voltage exceeds 5.5V. The XC6217C18AMR-G must be selected, as it supports input voltages up to 6V.
