Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C503B-BCS-CW0Y0452-030 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: CreeLED, Inc.
• Color: Blue
• Wavelength - Dominant: 470nm
• Voltage - Forward (Vf) Typical: 3.2V
• Current - Test: 20mA
• Lens Size: 5.00mm Dia
• Lens Style: Round with Domed Top
• Viewing Angle: 30°
• Mounting Type: Through Hole
• Package / Case: Radial
• Product Status: Active

Allowable Variation Parameters:

• Millicandela Rating: Brightness variation within the same product line
• Height (Max): Minor dimensional tolerance
• Packaging Format: Tape & Box (TB) to Cut Tape (CT) conversion
• RoHS Compliance Level: RoHS Compliant to ROHS3 Compliant

The substitute part C503B-BCS-CX0Y0452 maintains all mandatory parameters while offering increased brightness (6190mcd) and alternative packaging (Cut Tape), making it functionally equivalent for applications where higher luminous intensity is acceptable.

Parameter Comparison

Engineering Selection Recommendations

C503B-BCS-CW0Y0452-030 (Primary Selection): Select this part when Tape & Box packaging is required for production workflows. RoHS Compliant status meets standard environmental regulations. Brightness rating of 5600mcd is suitable for standard indication applications.

C503B-BCS-CX0Y0452 (Substitute Selection): Select this part when Cut Tape packaging is acceptable or preferred for automated assembly processes. ROHS3 Compliant status provides enhanced environmental compliance. The increased brightness of 6190mcd accommodates applications requiring higher luminous intensity without electrical parameter changes. Maximum height increases by 0.25mm (12.70mm vs 12.45mm), which must be verified against PCB clearance constraints.

Both parts maintain identical electrical characteristics (3.2V forward voltage, 20mA test current) and optical properties (470nm wavelength, 30° viewing angle), ensuring functional interchangeability in circuit design.

Frequently Asked Questions (FAQ)

Q: Can C503B-BCS-CX0Y0452 be used as a direct replacement for C503B-BCS-CW0Y0452-030?

A: Yes, with packaging and brightness considerations. Both parts share identical electrical specifications (3.2V, 20mA) and optical wavelength (470nm). The substitute offers higher brightness (6190mcd vs 5600mcd) and Cut Tape packaging instead of Tape & Box. Verify that the 0.25mm height increase (12.70mm vs 12.45mm) does not conflict with PCB layout constraints.

Q: What is the difference between Tape & Box and Cut Tape packaging?

A: Tape & Box (TB) packaging includes a protective box for storage and manual handling, suitable for lower-volume or mixed-component assembly. Cut Tape (CT) packaging provides individual component strips optimized for automated pick-and-place equipment. Both formats contain the same component; packaging selection depends on assembly process requirements.

Q: Does the brightness difference between 5600mcd and 6190mcd affect circuit design?

A: No. Both parts operate at identical forward voltage (3.2V) and test current (20mA). The brightness difference results from manufacturing variation within the same product line. Circuit design remains unchanged; brightness perception may increase slightly with the substitute part.

Q: Are there compliance differences between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 Compliant represents an updated compliance standard with additional restricted substance requirements compared to RoHS Compliant. Both statuses indicate environmental compliance; ROHS3 is the more current standard. Both parts are REACH Unaffected and classified as EAR99.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided PCB layout accommodates the maximum height variation of 0.25mm and assembly processes support the packaging format of the selected part. Electrical and optical characteristics are equivalent, ensuring circuit functionality remains unchanged.
