Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C503B-BCS-CW0X0452 is determined by the following critical parameters:

• Color: Blue
• Dominant Wavelength: 470nm
• Forward Voltage (Vf): 3.2V
• Test Current: 20mA
• Viewing Angle: 30°
• Mounting Type: Through Hole
• Lens Configuration: Round with Domed Top, Colorless, Clear
• Package Type: Radial

The HLMP-CB3A-UV0DD from Broadcom Limited meets all substitution criteria. Both components share identical electrical specifications (3.2V forward voltage, 20mA test current, 470nm dominant wavelength, 30° viewing angle) and compatible mechanical configurations (through-hole radial mounting, 5mm round domed lens, colorless clear lens). The substitute part maintains functional equivalence within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the C503B-BCS-CW0X0452 and HLMP-CB3A-UV0DD are active products with current manufacturing status. The C503B-BCS-CW0X0452 maintains RoHS Compliance, while the HLMP-CB3A-UV0DD meets ROHS3 Compliance, representing an enhanced regulatory standard. Both components carry REACH Unaffected status and EAR99 ECCN classification.

Selection between these parts should be based on:

• PCB layout constraints: The HLMP-CB3A-UV0DD has a maximum height of 8.90mm compared to 12.70mm for the C503B-BCS-CW0X0452, which may be relevant for applications with height restrictions.
• Luminous intensity requirements: The C503B-BCS-CW0X0452 delivers 4430mcd versus 4350mcd for the HLMP-CB3A-UV0DD, a 1.8% difference within typical application tolerances.
• Supply chain availability: Current inventory shows 3354 units of the C503B-BCS-CW0X0452 and 2704 units of the HLMP-CB3A-UV0DD.

Frequently Asked Questions (FAQ)

Q: Can the HLMP-CB3A-UV0DD directly replace the C503B-BCS-CW0X0452 in existing designs?

A: Yes, within the constraints of PCB layout. Both components share identical electrical specifications (3.2V forward voltage, 20mA test current, 470nm wavelength, 30° viewing angle) and compatible through-hole radial mounting. The primary design consideration is the height difference: 8.90mm versus 12.70mm maximum height.

Q: What is the brightness difference between these two LEDs?

A: The C503B-BCS-CW0X0452 produces 4430mcd at 20mA test current, while the HLMP-CB3A-UV0DD produces 4350mcd. This represents an 80mcd difference (1.8% variation), which is typically negligible for indication applications.

Q: Are both parts RoHS compliant?

A: Yes. The C503B-BCS-CW0X0452 is RoHS Compliant, and the HLMP-CB3A-UV0DD is ROHS3 Compliant. Both meet regulatory requirements for hazardous substance restrictions.

Q: What is the significance of the T-1 3/4 package designation for the HLMP-CB3A-UV0DD?

A: T-1 3/4 refers to the lens diameter and form factor. Both components use 5mm round domed lenses and are mechanically compatible in through-hole applications, though the overall component height differs.

Q: Can I use these parts interchangeably in high-volume production?

A: Electrical and optical performance are equivalent within specified parameters. Mechanical fit must be verified against PCB layout, particularly regarding the 3.8mm height difference. Both components maintain active product status with current manufacturing support.
