C566C-BFE-CT0V0352 Equivalent & Substitute Parts

Part Overview

The C566C-BFE-CT0V0352 is a blue diffused 5mm oval through-hole LED from CreeLED, Inc., designed for indication applications with a dominant wavelength of 468nm and a forward voltage of 3.4V at 20mA test current. This part is currently obsolete, making identification of compatible substitute components essential for ongoing production support, design updates, and inventory management. The Screen Master® series designation indicates this component was part of a specialized product line. Locating functionally equivalent alternatives ensures continuity in applications requiring blue LED indication with matching electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the C566C-BFE-CT0V0352 is determined by strict alignment of the following critical parameters:

Electrical Compatibility:

• Forward voltage (Vf): 3.4V (identical)
• Test current: 20mA (identical)
• Wavelength range: Blue spectrum (468nm–470nm acceptable variation within blue LED specification)

Mechanical Compatibility:

• Lens size: 5.20mm x 4.60mm (identical)
• Lens style: Oval with domed top (identical)
• Mounting type: Through hole radial (identical)
• Package case: Radial (identical)
• Height: 7.80mm maximum (identical)

Regulatory & Environmental:

• RoHS compliance: Required
• Moisture sensitivity: MSL 1 (unlimited)
• REACH status: Unaffected

The substitute part C566D-BFE-CU34Q3S2 meets all these criteria, with the only variation being a minor wavelength shift from 468nm to 470nm (within acceptable blue LED tolerance) and an increased millicandela rating (2412mcd vs. 2050mcd), which represents improved performance rather than incompatibility.

Parameter Comparison

Engineering Selection Recommendations

The C566D-BFE-CU34Q3S2 is the direct substitute for the obsolete C566C-BFE-CT0V0352. Both components are manufactured by CreeLED, Inc., and maintain identical electrical specifications (3.4V forward voltage, 20mA test current) and mechanical form factors (5.20mm x 4.60mm oval lens, 7.80mm height, through-hole radial mounting).

The substitute part carries Active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain RoHS compliance and MSL 1 moisture sensitivity rating, satisfying regulatory requirements for current production environments.

The wavelength variation from 468nm to 470nm represents a 2nm shift within the blue LED spectrum and does not constitute a functional incompatibility. The increased luminous intensity (2412mcd vs. 2050mcd) in the substitute provides enhanced brightness performance, which is advantageous for indication applications.

The substitute is available in Tape & Box packaging, supporting automated assembly processes where applicable.

Frequently Asked Questions (FAQ)

Q: Can C566D-BFE-CU34Q3S2 be used as a direct replacement for C566C-BFE-CT0V0352?

A: Yes. Both parts share identical forward voltage (3.4V), test current (20mA), mechanical dimensions (5.20mm x 4.60mm lens, 7.80mm height), lens style (oval with domed top), and mounting type (through-hole radial). The 2nm wavelength difference (468nm to 470nm) falls within acceptable blue LED specification tolerances.

Q: What is the significance of the wavelength shift from 468nm to 470nm?

A: The shift represents a minor variation within the blue LED spectrum. Both wavelengths are classified as blue indication LEDs and are visually indistinguishable to the human eye. This variation does not affect circuit compatibility or functional performance in indication applications.

Q: Does the increased brightness (2412mcd vs. 2050mcd) affect compatibility?

A: No. Higher luminous intensity is a performance enhancement, not a compatibility issue. If the original design operated at 20mA with 2050mcd, the substitute will operate at the same current with increased brightness. Circuit current-limiting resistors remain unchanged.

Q: Are there any regulatory or compliance differences?

A: No. Both parts are RoHS compliant, carry MSL 1 moisture sensitivity rating, and are REACH unaffected. Regulatory status is identical.

Q: What packaging options are available for the substitute?

A: The C566D-BFE-CU34Q3S2 is supplied in Tape & Box (TB) packaging, suitable for automated pick-and-place assembly. The original part packaging specification was not provided.

Q: Why is the original part obsolete?

A: Product obsolescence is determined by the manufacturer. The C566C-BFE-CT0V0352 has reached end-of-life status. The C566D-BFE-CU34Q3S2 is the active equivalent from the same manufacturer and series.

Q: Are viewing angle differences significant?

A: The main part specifies 70°, 35° while the substitute specifies 70° x 30°. Both represent wide-angle diffused LED characteristics suitable for general indication applications. The minor difference does not affect functional compatibility in standard circuit designs.
