Key Parameters

Substitute Part Grouping Explanation

Substitution of the C566C-BFE-CT0U0342 is determined by strict alignment of the following electrical and mechanical parameters:

• Color and wavelength matching (Blue, 470nm dominant wavelength)
• Forward voltage compatibility (3.4V typical)
• Test current specification (20mA)
• Physical form factor (5mm oval diffused lens, through-hole mounting)
• Mechanical dimensions (5.20mm x 4.60mm lens size, 7.80mm maximum height)
• Compliance certifications (RoHS Compliant, REACH Unaffected)

The substitute part C566D-BFE-CU14Q3S2 meets all these criteria while offering improved luminous intensity (2042mcd versus 1615mcd) and active product status, making it a direct functional replacement.

Parameter Comparison
