Substitute Part Grouping Explanation

Substitute parts for the C503C-ACN-CYCZA342 are qualified based on the following criteria:

• Color and Wavelength: All substitutes maintain amber color at 591nm dominant wavelength
• Electrical Characteristics: Forward voltage (Vf) of 2.1V and test current of 20mA are identical across all parts
• Optical Performance: Millicandela rating, lens transparency (Clear), and viewing angle (30°) are consistent
• Mechanical Compatibility: All parts feature 5mm round domed lens, through-hole radial mounting, and maximum height of 10.10mm
• Regulatory Compliance: All substitutes are RoHS Compliant, REACH Unaffected, and carry identical MSL rating (1 - Unlimited)

The three substitute parts (C503B-ACN-CY0Z0252, C503B-ACN-CY0Z0252-030, C503B-ACN-CY0Z0342) differ only in base product designation and inventory availability, with no variation in electrical or mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the C503C-ACN-CYCZA342 for through-hole amber LED indication circuits. Selection among these parts should be based on:

• Inventory Availability: C503B-ACN-CY0Z0252-030 offers the highest stock level at 19,953 pieces
• Regulatory Compliance: All parts maintain identical RoHS and REACH compliance status
• Moisture Sensitivity: All parts carry MSL rating of 1 (Unlimited), suitable for standard storage and handling conditions
• Optical Performance: Substitute parts deliver slightly higher luminous intensity (8930mcd vs. 8650mcd), which remains within acceptable tolerance for indication applications

Frequently Asked Questions (FAQ)

Q: Can C503B-ACN-CY0Z0252, C503B-ACN-CY0Z0252-030, and C503B-ACN-CY0Z0342 be used interchangeably with C503C-ACN-CYCZA342?

A: Yes. All parts share identical electrical characteristics (2.1V forward voltage, 20mA test current), optical specifications (591nm amber, 30° viewing angle), and mechanical form factor (5mm round through-hole radial package). The base product number change (C503B vs. C503C) does not affect functional equivalence.

Q: What is the difference between the three substitute parts?

A: The three substitutes differ only in part number designation and current inventory levels. Electrical, optical, and mechanical parameters are identical across all three parts.

Q: Are there any compliance differences between the main part and substitutes?

A: No. All parts carry identical RoHS Compliance, REACH Unaffected status, MSL rating of 1 (Unlimited), and Active product status.

Q: Does the higher millicandela rating (8930mcd vs. 8650mcd) in substitute parts affect circuit design?

A: The substitute parts deliver approximately 3.2% higher luminous intensity. This represents a minor increase within normal manufacturing tolerance and does not require circuit redesign for indication applications.

Q: Are packaging and mounting specifications identical?

A: Yes. All parts use Cut Tape (CT) packaging, radial through-hole mounting, 5mm round domed lens, and maximum height of 10.10mm.
