Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C503B-AAS-CZ0A0342 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Amber color (591nm dominant wavelength)
• 5.00mm diameter round lens with domed top
• 2.1V forward voltage
• 20mA test current
• 15° viewing angle
• Through-hole radial mounting
• RoHS and REACH compliance

Allowable Variation Parameters:

• Millicandela rating (brightness): 12500mcd baseline; substitutes may vary within the amber LED product line
• Lens transparency and color designation: Clear colorless lens preferred but alternative designations acceptable if optical properties remain equivalent
• Height (Max): Minor variations acceptable (13.20mm to 13.30mm range)
• Packaging format: Cut Tape (CT), Tape & Box (TB), or equivalent
• Product status: Active status preferred for long-term availability

Three substitute parts meet these criteria and are grouped as follows:

Direct Manufacturer Substitute (Higher Brightness): C503B-AAS-CZ0B0342 — Active product with 15850mcd rating and 590nm wavelength, representing a higher-brightness variant within the same product family.

Parametric Equivalents (Comparable Brightness): C503B-AAS-CA0B0342 and C503B-AAS-CY0B0252 — Both active products with brightness ratings (13000mcd and 14680mcd respectively) and 591nm wavelength matching the original specification more closely.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement with Higher Brightness: C503B-AAS-CZ0B0342 is an active product with ROHS3 compliance and significantly higher inventory availability (8519 pcs). This part operates at 590nm wavelength with 15850mcd brightness, representing a 26.8% increase over the original specification. Selection is appropriate where increased brightness does not conflict with circuit design constraints or optical requirements.

For Closest Parametric Match: C503B-AAS-CA0B0342 and C503B-AAS-CY0B0252 both maintain 591nm wavelength matching and clear colorless lens specifications identical to the original part. C503B-AAS-CA0B0342 provides 13000mcd (3.8% above original), while C503B-AAS-CY0B0252 provides 14680mcd (17.4% above original). Both are active products with standard RoHS compliance and adequate inventory levels. These parts are preferred where wavelength and lens transparency specifications must remain unchanged.

All substitute parts maintain identical electrical characteristics (2.1V forward voltage, 20mA test current, 15° viewing angle), mechanical form factor (5mm round domed lens, through-hole radial mounting), and regulatory compliance (RoHS, REACH, MSL 1).

Frequently Asked Questions (FAQ)

Q: Can C503B-AAS-CZ0B0342 be used as a direct replacement for C503B-AAS-CZ0A0342?

A: Yes. Both parts share identical electrical specifications (2.1V, 20mA, 15° viewing angle), mechanical form factor (5mm round through-hole radial), and regulatory compliance. The primary difference is brightness (15850mcd vs. 12500mcd) and wavelength (590nm vs. 591nm). Substitution is valid provided circuit design accommodates the higher brightness output.

Q: What is the difference between C503B-AAS-CA0B0342 and C503B-AAS-CY0B0252?

A: Both parts are parametric equivalents with identical wavelength (591nm), lens properties (clear colorless), electrical ratings (2.1V, 20mA), and mechanical specifications. The difference is brightness: C503B-AAS-CA0B0342 provides 13000mcd while C503B-AAS-CY0B0252 provides 14680mcd. Selection depends on brightness requirements within the application circuit.

Q: Are there packaging differences between substitute parts?

A: Yes. C503B-AAS-CZ0B0342 is supplied in Cut Tape (CT) format, while C503B-AAS-CA0B0342 and C503B-AAS-CY0B0252 are supplied in Tape & Box (TB) format. Packaging selection depends on procurement volume and assembly line requirements. All parts are compatible with standard through-hole assembly processes.

Q: Do all substitute parts meet the same compliance standards?

A: All substitute parts are RoHS compliant and REACH unaffected with MSL 1 (unlimited moisture sensitivity). C503B-AAS-CZ0B0342 carries ROHS3 certification, while C503B-AAS-CA0B0342 and C503B-AAS-CY0B0252 carry standard RoHS certification. All meet regulatory requirements for industrial and commercial applications.

Q: What is the height difference between the original part and substitutes?

A: The original C503B-AAS-CZ0A0342 has a maximum height of 13.30mm. C503B-AAS-CZ0B0342 and C503B-AAS-CA0B0342 have maximum heights of 13.20mm (0.10mm shorter), while C503B-AAS-CY0B0252 matches the original at 13.30mm. These variations are within standard mechanical tolerances for through-hole PCB assembly.
