Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C503B-ACN-CW0X0342 is determined by the following critical parameters:

• Color and Wavelength: Amber at 591nm dominant wavelength (non-negotiable for color-specific applications)
• Lens Configuration: 5mm round with domed top, clear transparency (mechanical and optical compatibility)
• Forward Voltage: 2.1V typical (circuit design compatibility)
• Mounting Type: Through-hole radial (PCB layout compatibility)
• Physical Dimensions: 10.10mm maximum height (mechanical fit)
• Viewing Angle: 30° (optical performance specification)

The identified substitute part C503B-ACN-CX0Z0342 maintains all critical parameters while offering active product status and higher luminous intensity (8090mcd versus 4430mcd at identical test conditions).

Parameter Comparison

Engineering Selection Recommendations

The C503B-ACN-CX0Z0342 is the direct substitute for the obsolete C503B-ACN-CW0X0342. Both parts share identical electrical characteristics (2.1V forward voltage, 20mA test current), mechanical dimensions (5mm lens, 10.10mm height), and optical properties (591nm amber, 30° viewing angle).

The substitute part offers the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• RoHS compliance certification provides regulatory alignment for new designs
• Higher luminous intensity (8090mcd) at identical operating conditions allows for reduced current operation or improved visibility in the same application
• Identical packaging and mounting configuration enables direct PCB layout compatibility

Selection of C503B-ACN-CX0Z0342 is appropriate for all applications currently using C503B-ACN-CW0X0342 without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can C503B-ACN-CX0Z0342 be used as a direct replacement for C503B-ACN-CW0X0342?

A: Yes. Both parts share identical forward voltage (2.1V), test current (20mA), lens configuration (5mm round clear), wavelength (591nm amber), viewing angle (30°), and physical dimensions (10.10mm height). The substitute is mechanically and electrically compatible without circuit redesign.

Q: What is the difference in luminous intensity between these parts?

A: The substitute C503B-ACN-CX0Z0342 delivers 8090mcd compared to 4430mcd for the main part, both measured at 20mA test current. This represents approximately 82% higher luminous intensity at identical operating conditions.

Q: Does the higher brightness of the substitute part require circuit changes?

A: No. Both parts operate at the same forward voltage and test current. The increased brightness is an inherent characteristic of the substitute part and does not necessitate circuit modification. If reduced brightness is required, current limiting can be adjusted independently.

Q: What is the packaging difference between these parts?

A: The main part C503B-ACN-CW0X0342 packaging is not specified. The substitute C503B-ACN-CX0Z0342 is supplied in Tape & Box (TB) packaging. Both use identical 5mm round radial through-hole configuration.

Q: Are there compliance differences between these parts?

A: The substitute C503B-ACN-CX0Z0342 carries RoHS compliance certification, while the main part does not specify RoHS status. Both parts are REACH Unaffected and carry EAR99 ECCN classification.

Q: Why is the main part listed as obsolete?

A: The C503B-ACN-CW0X0342 is classified as obsolete by the manufacturer. The C503B-ACN-CX0Z0342 is the active equivalent and is recommended for all new designs and ongoing procurement.
