Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C503B-BCS-CW0X0451 is determined by strict alignment of the following parameters:

• Color specification (Blue)
• Dominant wavelength (470nm)
• Forward voltage (3.2V)
• Test current (20mA)
• Mounting type (Through Hole)
• Lens transparency (Clear)
• Viewing angle (30°)
• Radial package configuration

The HLMP-CB3A-UV0DD meets these substitution criteria. While minor variations exist in physical dimensions and millicandela rating, the electrical characteristics and optical properties remain within the functional scope of the original component specification.

Parameter Comparison

Engineering Selection Recommendations

Both the C503B-BCS-CW0X0451 and HLMP-CB3A-UV0DD maintain active product status with full regulatory compliance. The C503B-BCS-CW0X0451 carries RoHS Compliant certification, while the HLMP-CB3A-UV0DD meets ROHS3 Compliant standards. Both components are REACH Unaffected and classified under ECCN EAR99. Selection between these parts should be based on availability, packaging format (Bulk versus Cut Tape), and physical height constraints within the application. The HLMP-CB3A-UV0DD offers a reduced maximum height of 8.90mm compared to 12.70mm for the C503B-BCS-CW0X0451, which may be advantageous in space-constrained designs.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for substitution? A: Forward voltage (3.2V), test current (20mA), and dominant wavelength (470nm) must remain constant. Both parts operate identically at these specifications.

Q: Are there physical differences between these parts? A: Yes. The C503B-BCS-CW0X0451 has a maximum height of 12.70mm, while the HLMP-CB3A-UV0DD measures 8.90mm maximum height. Both use 5mm lens sizes with identical optical properties (clear, round domed, 30° viewing angle).

Q: What is the difference between packaging formats? A: The C503B-BCS-CW0X0451 is supplied in Bulk packaging, while the HLMP-CB3A-UV0DD is supplied in Cut Tape (CT) format. This affects handling and automated assembly compatibility.

Q: Do compliance certifications differ? A: The C503B-BCS-CW0X0451 is RoHS Compliant, while the HLMP-CB3A-UV0DD is ROHS3 Compliant. Both are REACH Unaffected and carry identical ECCN and HTSUS classifications.

Q: Is the millicandela rating difference significant? A: The C503B-BCS-CW0X0451 delivers 4430mcd while the HLMP-CB3A-UV0DD delivers 4350mcd at identical test conditions. This 80mcd difference represents approximately 1.8% variation and falls within typical LED manufacturing tolerances.
