Key Parameters

Substitute Part Grouping Explanation

Substitution for the S-818A27AMC-BGHT2G is determined by the following critical parameters:

• Output voltage specification: 2.7V fixed
• Output current capability: 150mA minimum
• Input voltage tolerance: 10V maximum
• Package compatibility: SOT-23-5 form factor
• Operating temperature range: -40°C to 85°C
• Control features: Enable function required
• Regulatory compliance: ROHS3 and REACH requirements

Two substitute parts meet these criteria with varying performance characteristics in dropout voltage, quiescent current, and PSRR specifications.

Parameter Comparison

Engineering Selection Recommendations

The S-L2980A27MC-TF-U from ABLIC Inc. is a parametric equivalent offering superior performance characteristics. This part maintains identical output voltage and current specifications while delivering improved dropout voltage performance (0.2V @ 50mA versus 0.61V @ 60mA) and higher PSRR (70dB @ 1kHz). The S-L2980A27MC-TF-U carries Active product status, ensuring long-term availability and supply continuity. Both parts share identical packaging and thermal operating ranges.

The XC6204B272MR-G from Torex Semiconductor Ltd provides an alternative cross-manufacturer substitute with comparable electrical performance. This device offers moderate dropout voltage (0.37V @ 100mA) and equivalent PSRR (70dB @ 10kHz). The XC6204B272MR-G includes Over Current protection features and maintains Active product status. Pin compatibility and thermal specifications align with the original part, though the supplier device package designation differs (SOT-25-5 versus SOT-23-5).

All three parts maintain ROHS3 compliance and REACH unaffected status, supporting regulatory requirements for current production environments.

Frequently Asked Questions (FAQ)

Q: Can the S-L2980A27MC-TF-U directly replace the S-818A27AMC-BGHT2G in existing designs?

A: Yes. Both parts share identical output voltage (2.7V), output current (150mA), input voltage tolerance (10V maximum), package form factor (SOT-23-5), and operating temperature range (-40°C to 85°C). The S-L2980A27MC-TF-U provides improved electrical performance with lower dropout voltage and higher PSRR.

Q: What are the key differences between the S-L2980A27MC-TF-U and XC6204B272MR-G?

A: Both parts meet the core substitution criteria. The S-L2980A27MC-TF-U is from the same manufacturer (ABLIC Inc.) with identical package designation. The XC6204B272MR-G is from Torex Semiconductor Ltd and includes Over Current protection. The XC6204B272MR-G has higher quiescent current (120 µA versus 1 µA), which may impact low-power applications.

Q: Are there package compatibility concerns with these substitutes?

A: The S-L2980A27MC-TF-U uses SOT-23-5 packaging, identical to the original part. The XC6204B272MR-G uses SOT-25-5 packaging. Both maintain the SC-74A, SOT-753 case designation. PCB layout and footprint compatibility should be verified for the XC6204B272MR-G due to the package variant.

Q: Why is the S-818A27AMC-BGHT2G marked as Not For New Designs?

A: This designation indicates the part is in mature or end-of-life status. The S-L2980A27MC-TF-U and XC6204B272MR-G both carry Active product status, ensuring continued manufacturing and supply availability for new and ongoing production requirements.

Q: Do all three parts meet current regulatory compliance standards?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.
