C503C-ACS-CYAZA252 Equivalent & Substitute Parts

Part Overview

The C503C-ACS-CYAZA252 is an amber 5mm through-hole LED manufactured by CreeLED, Inc., designed for indication applications with a dominant wavelength of 591nm. This component is actively produced and RoHS compliant. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, inventory optimization, or supply chain continuity while maintaining functional compatibility in circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the C503C-ACS-CYAZA252 are qualified based on the following critical parameters that determine functional equivalence:

• Electrical Parameters: Forward voltage (2.1V), test current (20mA), and wavelength (591nm amber) must remain constant
• Optical Parameters: Color (amber), lens transparency (clear), lens style (round with domed top), and viewing angle (30°) must match
• Mechanical Parameters: Lens size (5.00mm diameter), mounting type (through hole), and package type (radial) must be identical
• Compliance: RoHS compliance and MSL rating must be maintained

The identified substitutes C503B-ACS-CX0Z0252 and C503B-ACS-CY0Z0252-030 meet all these criteria. Variations in millicandela rating and packaging format (cut tape versus tape & box) do not affect functional substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—C503C-ACS-CYAZA252, C503B-ACS-CX0Z0252, and C503B-ACS-CY0Z0252-030—are active products manufactured by CreeLED, Inc., with full RoHS compliance and MSL rating of 1 (unlimited moisture sensitivity). They are electrically and mechanically interchangeable in through-hole circuit applications requiring amber 591nm indication LEDs with 2.1V forward voltage and 30° viewing angle.

Selection between these parts may be based on packaging availability (tape & box versus cut tape), inventory levels, or millicandela brightness requirements within the specified range (7980mcd to 8930mcd). Height variation (12.80mm versus 12.70mm) is negligible for standard PCB mounting applications.

Frequently Asked Questions (FAQ)

Q: Can C503B-ACS-CX0Z0252 and C503B-ACS-CY0Z0252-030 be used interchangeably with C503C-ACS-CYAZA252 in existing designs?

A: Yes. All three parts share identical electrical parameters (2.1V forward voltage, 20mA test current), optical properties (amber color, 591nm wavelength, 30° viewing angle), and mechanical specifications (5mm diameter round lens, through-hole radial package). They are functionally equivalent for circuit applications.

Q: What is the difference between the substitute parts?

A: The primary differences are millicandela rating (C503B-ACS-CX0Z0252 at 8090mcd and C503B-ACS-CY0Z0252-030 at 8930mcd versus C503C-ACS-CYAZA252 at 7980mcd) and packaging format (cut tape for C503B variants versus tape & box for C503C). Height specifications differ marginally (12.70mm versus 12.80mm).

Q: Does packaging format affect electrical or mechanical compatibility?

A: No. Packaging format (cut tape or tape & box) affects only supply chain logistics and handling. Once components are removed from packaging, electrical and mechanical properties remain identical.

Q: Are all parts RoHS compliant?

A: Yes. C503C-ACS-CYAZA252, C503B-ACS-CX0Z0252, and C503B-ACS-CY0Z0252-030 are all RoHS compliant with MSL rating of 1 (unlimited).

Q: Can brightness differences between parts affect circuit performance?

A: Brightness (millicandela rating) is an optical characteristic that does not affect electrical circuit behavior. Selection based on brightness depends on application requirements for indication visibility. All three parts operate at identical voltage and current specifications.
