Key Parameters

Substitute Part Grouping Explanation

Substitution for the XR46083ECF-C2 is determined by the following critical parameters:

• Single output LED driver topology
• Linear driver type
• Supply voltage capability (maximum rating)
• Output voltage capability
• Surface mount packaging compatibility
• Operating temperature range
• Moisture sensitivity classification

The two identified substitute parts (AL5811FF-7 and BCR420UE6433HTMA1) maintain the core functional requirement of single-output linear LED driver operation. However, each substitute presents distinct electrical and packaging characteristics that must be evaluated against the original application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are currently in active production status, providing supply continuity advantages over the obsolete XR46083ECF-C2.

AL5811FF-7 (Diodes Incorporated): This substitute operates within a 60V maximum supply voltage and supports output voltage range of 1V to 60V. The part includes PWM dimming capability and operates across an extended temperature range (-40°C to 125°C). It is packaged in a 6-UDFN format and carries ROHS3 compliance certification. This option is suitable for applications where the original 80V supply voltage and 130V output voltage are not required.

BCR420UE6433HTMA1 (Infineon Technologies): This substitute is qualified to AEC-Q101 automotive standards and operates with a 40V maximum supply voltage and 40V output voltage. It is packaged in SC-74/SOT-457 format and carries ROHS3 compliance certification. This option is appropriate for automotive-grade lighting applications where the lower voltage ratings are compatible with system requirements.

Selection between these substitutes depends on whether the application voltage requirements align with the reduced maximum ratings of each alternative part.

Frequently Asked Questions (FAQ)

Q: Can AL5811FF-7 directly replace XR46083ECF-C2 in all applications?

A: AL5811FF-7 is functionally equivalent as a single-output linear LED driver. However, the maximum supply voltage is reduced from 80V to 60V, and the maximum output voltage is reduced from 130V to 60V. Substitution is valid only if the application operates within these lower voltage specifications.

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

A: AL5811FF-7 supports PWM dimming and operates to 125°C, while BCR420UE6433HTMA1 is automotive-qualified (AEC-Q101) with lower voltage ratings (40V max). AL5811FF-7 is packaged in 6-UDFN format; BCR420UE6433HTMA1 uses SC-74/SOT-457 packaging.

Q: Are both substitute parts RoHS compliant?

A: Yes, both AL5811FF-7 and BCR420UE6433HTMA1 are ROHS3 compliant. The original XR46083ECF-C2 RoHS status is not specified in the provided data.

Q: Does package format affect substitution feasibility?

A: Yes. The original part is supplied as a die, while substitutes are packaged in standard surface-mount formats (6-UDFN and SC-74). PCB layout and assembly process modifications are required for substitution.

Q: Which substitute is recommended for high-temperature applications?

A: AL5811FF-7 supports operation to 125°C, exceeding the original part's 100°C maximum. BCR420UE6433HTMA1 operating temperature is not specified in the provided data.
