Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C503T-RAS-CX0A0CC2 is determined by the following critical parameters:

• Physical compatibility: 5mm round lens diameter, through-hole radial package, domed top lens style
• Electrical compatibility: Red color spectrum (wavelength range 620–630nm), forward voltage within acceptable circuit design tolerance, 20mA test current rating
• Optical compatibility: Clear lens transparency, viewing angle suitable for indication applications
• Regulatory compliance: REACH Unaffected status, MSL 1 rating

The substitute part C503B-RCS-CW0Z0AA2 meets these criteria with allowable variations in forward voltage (2.1V vs. 2.3V), brightness (7500mcd vs. 10490mcd), wavelength (624nm vs. 628nm), and viewing angle (30° vs. 15°). These variations remain within acceptable tolerances for red LED indication applications while maintaining identical physical form factor and regulatory status.

Frequently Asked Questions (FAQ)

Q: Can C503B-RCS-CW0Z0AA2 be used as a direct replacement for C503T-RAS-CX0A0CC2?

A: Yes. Both components share identical physical dimensions (5mm round lens, through-hole radial package), electrical test current (20mA), and regulatory compliance. The substitute operates at 2.1V forward voltage versus 2.3V, with 7500mcd brightness versus 10490mcd. These differences are within acceptable tolerances for red LED indication applications.

Q: What are the key differences between these parts?

A: The main differences are forward voltage (2.1V vs. 2.3V), brightness (7500mcd vs. 10490mcd), dominant wavelength (624nm vs. 628nm), viewing angle (30° vs. 15°), and product status (Active vs. Obsolete). Physical form factor and regulatory compliance are identical.

Q: Does the lower brightness of the substitute affect circuit design?

A: Circuit design must account for the 7500mcd brightness rating of the substitute versus 10490mcd of the main part. Forward voltage difference (0.2V) may require minor resistor adjustments in current-limiting circuits.

Q: Are there packaging differences?

A: The main part is supplied in standard packaging, while the substitute is supplied in Cut Tape (CT) packaging. Both use identical 5mm round through-hole radial package format suitable for PCB assembly.

Q: What is the viewing angle difference impact?

A: The substitute provides a wider viewing angle (30° vs. 15°), making it suitable for applications requiring broader light distribution. This is generally beneficial for indication applications.
