Substitute Part Grouping Explanation

Substitution for the C503B-BCS-CV0W0452 is determined by strict equivalence across the following critical parameters:

• Color and Wavelength: Blue 470nm dominant wavelength
• Lens Configuration: 5.00mm diameter round with domed top, clear colorless lens
• Electrical Characteristics: 3.2V typical forward voltage, 20mA test current
• Optical Performance: 30° viewing angle
• Mechanical Compatibility: Through-hole radial mounting, 12.70mm maximum height
• Environmental Compliance: MSL 1 (Unlimited), REACH Unaffected status

The substitute part C503B-BCS-CW0X0452 meets all these criteria while offering improved millicandela rating (4430mcd versus 3155mcd) and active product status with RoHS compliance.
