Substitute Part Grouping Explanation

The C503B-ACS-CY0Z0252-030 qualifies as a parametric equivalent based on the following critical parameters:

  • Color & Wavelength: Both parts emit amber light at 591nm dominant wavelength
  • Electrical Characteristics: Identical forward voltage (2.1V) and test current (20mA)
  • Mechanical Form Factor: Both feature 5mm round domed clear lenses with radial through-hole mounting
  • Viewing Angle: Both rated at 30° viewing angle
  • Compliance & Certifications: Both are RoHS Compliant, REACH Unaffected, and carry MSL 1 rating

The primary differences are packaging format (Tape & Box vs. Cut Tape) and luminous intensity variance (8650mcd vs. 8930mcd), which fall within acceptable tolerance ranges for amber LED indication applications.

Engineering Selection Recommendations

Both C503C-ACS-CYCZA252 and C503B-ACS-CY0Z0252-030 are Active products with identical compliance certifications (RoHS Compliant, REACH Unaffected). Selection between these parts should be based on:

  • Packaging Requirements: Choose C503C-ACS-CYCZA252 for Tape & Box format; select C503B-ACS-CY0Z0252-030 for Cut Tape format
  • Luminous Intensity Tolerance: The C503B variant provides slightly higher brightness (8930mcd vs. 8650mcd), acceptable for applications where increased visibility is beneficial
  • Height Tolerance: Both parts meet through-hole PCB mounting with minimal height variance (12.80mm vs. 12.70mm)
  • Supply Availability: C503B-ACS-CY0Z0252-030 shows higher inventory availability (5239 pcs vs. 655 pcs)

Frequently Asked Questions (FAQ)

Q: Can C503B-ACS-CY0Z0252-030 directly replace C503C-ACS-CYCZA252 in existing designs?

A: Yes. Both parts share identical electrical characteristics (2.1V forward voltage, 20mA test current), optical properties (591nm amber, 30° viewing angle), and mechanical form factor (5mm round through-hole radial). The primary difference is packaging format and a minor luminous intensity increase in the C503B variant.

Q: What is the significance of the packaging difference between Tape & Box and Cut Tape?

A: Tape & Box (TB) packaging is suitable for automated assembly lines with reel-fed pick-and-place equipment. Cut Tape (CT) packaging provides individual tape segments for lower-volume manual assembly or component kitting. Both formats contain identical components; selection depends on assembly process requirements.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts carry identical certifications: RoHS Compliant, REACH Unaffected, MSL 1 (Unlimited), ECCN EAR99, and HTSUS 8541.41.0000.

Q: How does the luminous intensity difference affect circuit design?

A: The C503B variant (8930mcd) provides approximately 3.2% higher brightness than the C503C variant (8650mcd). This difference is negligible for standard indication applications and does not require circuit redesign. Both parts operate at identical voltage and current specifications.

Q: Can these parts be mixed in the same production batch?

A: Yes, provided the application tolerates the minor luminous intensity variance and packaging format differences do not conflict with assembly equipment specifications.
