Key Parameters

Substitute Part Grouping Explanation

The substitute parts listed for the BCR401RE6327HTSA1 are identified based on functional category alignment within Power Management (PMIC) components. Both substitute parts operate as LED driver ICs with linear output stages and PWM dimming capability, placing them in the same functional family as current source and current regulation devices.

Substitution logic is based on the following criteria:

• Functional Category: All parts are Power Management (PMIC) components
• Mounting Type: All parts are surface mount devices
• Output Control: All parts provide regulated current output with control mechanisms
• Compliance: All parts meet ROHS3 and REACH requirements
• Packaging Standard: All parts use industry-standard surface mount packages

The substitute parts differ in specific electrical parameters (output current, supply voltage ranges) and package form factors, requiring engineering evaluation for circuit-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

Selection between the BCR401RE6327HTSA1 and its substitutes must account for the following factors:

Product Status Consideration: The BCR401RE6327HTSA1 carries "Not For New Designs" status, while both AL1791AFE-13 and MIC4802YME-TR are Active products. For new designs or long-term production, Active-status parts provide extended availability and manufacturer support.

Compliance Alignment: All three parts meet ROHS3 and REACH requirements, ensuring regulatory compatibility across applications.

Electrical Parameter Matching: The BCR401RE6327HTSA1 operates at 18V input with 60mA output. The AL1791AFE-13 supports a wider input range (6.5V - 30V) with higher output current (1A), while the MIC4802YME-TR operates at lower supply voltages (3V - 5.5V) with 800mA output. Circuit-level voltage and current requirements must be evaluated to determine compatibility.

Package Considerations: The BCR401RE6327HTSA1 uses SOT-143R packaging, while substitutes use different form factors (14-UFDFN and 8-SOIC). PCB layout modifications may be required for physical integration.

Frequently Asked Questions (FAQ)

Q: Can the AL1791AFE-13 directly replace the BCR401RE6327HTSA1 in existing designs?

A: Direct replacement requires verification of circuit-level compatibility. The AL1791AFE-13 has a higher output current rating (1A vs. 60mA) and different package form factor (14-UFDFN vs. SOT-143R). Input voltage range compatibility (6.5V - 30V vs. 18V) must be confirmed for your specific application.

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

A: The AL1791AFE-13 supports higher input voltages (up to 30V) and higher output current (1A), while the MIC4802YME-TR is designed for lower supply voltage applications (3V - 5.5V) with 800mA output. Selection depends on your circuit's voltage and current requirements.

Q: Are all three parts RoHS compliant?

A: Yes, all three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Does the MSL rating difference between parts affect substitution?

A: The BCR401RE6327HTSA1 and AL1791AFE-13 both have MSL 1 (Unlimited), while the MIC4802YME-TR has MSL 2 (1 Year). MSL rating affects moisture exposure limits during storage and handling. Higher MSL ratings require stricter moisture control protocols.

Q: Why is the BCR401RE6327HTSA1 marked "Not For New Designs"?

A: This status indicates the part has been superseded in Infineon's product line. Existing inventory remains available for legacy system support, but new designs should evaluate the active substitute parts listed.
