C503B-AAS-CA0C0342-015 Equivalent & Substitute Parts

Part Overview

The C503B-AAS-CA0C0342-015 is an amber LED indication component manufactured by CreeLED, Inc., designed for through-hole mounting applications. This 5mm round LED operates at 2.1V forward voltage with a dominant wavelength of 590nm and delivers 22,450mcd at 20mA test current. The component is RoHS compliant and carries an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling. Product status is Active, ensuring continued availability and support for production applications.

Substitute parts become necessary when addressing supply chain constraints, packaging format requirements, or minor wavelength variations within the amber spectrum that remain functionally equivalent for indication purposes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C503B-AAS-CA0C0342-015 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Color: Amber
• Lens Size: 5.00mm Dia
• Voltage - Forward (Vf): 2.1V
• Current - Test: 20mA
• Millicandela Rating: 22,450mcd
• Viewing Angle: 15°
• Mounting Type: Through Hole
• Package / Case: Radial
• RoHS Status: RoHS Compliant
• MSL Rating: 1 (Unlimited)

Allowed Variation Parameters:

• Wavelength - Dominant: 590nm to 591nm (within amber spectrum)
• Height (Max): 11.30mm to 13.30mm (mechanical fit dependent on PCB design)
• Packaging Format: Tape & Box (TB) or Cut Tape (CT) (logistics consideration, not electrical)

All three substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status with RoHS compliance and MSL 1 (Unlimited) ratings, ensuring regulatory alignment and supply chain stability.

C503B-AAN-CA0C0342-015 provides the highest inventory availability (20,834 pcs) while maintaining identical electrical specifications and wavelength (590nm) to the main part. Height reduction to 11.30mm may require PCB layout verification for clearance-constrained applications. Packaging format is Cut Tape (CT).

C503B-AAN-CA0C0252-015 offers substantial inventory (9,112 pcs) with wavelength at 591nm (within amber spectrum tolerance) and reduced height of 11.30mm. Cut Tape (CT) packaging applies.

C503B-AAS-CA0C0252-015 maintains the original height specification (13.30mm) with wavelength at 591nm and provides 7,253 pcs inventory. Cut Tape (CT) packaging applies.

Selection should prioritize inventory availability and packaging format requirements for your procurement workflow, as all parts are electrically and mechanically equivalent within specified parameters.

Frequently Asked Questions (FAQ)

Q: Can C503B-AAN-CA0C0342-015 replace C503B-AAS-CA0C0342-015 in production?

A: Yes. Both parts share identical electrical specifications (2.1V, 20mA, 22,450mcd, 590nm wavelength, 15° viewing angle). The difference is packaging format (Cut Tape vs. Tape & Box) and height (11.30mm vs. 13.30mm). Height compatibility depends on your PCB design clearance.

Q: What is the significance of the wavelength difference between 590nm and 591nm?

A: Both wavelengths fall within the amber spectrum and are visually indistinguishable for indication applications. The 1nm difference reflects normal manufacturing tolerance within the amber color classification and does not affect functional performance.

Q: Does packaging format affect electrical performance?

A: No. Tape & Box (TB) and Cut Tape (CT) are logistics and handling formats only. Electrical and optical characteristics remain identical regardless of packaging.

Q: Are all substitute parts RoHS compliant?

A: Yes. All parts listed carry RoHS Compliant status and are suitable for applications requiring regulatory compliance.

Q: What does MSL 1 (Unlimited) mean for component handling?

A: MSL 1 indicates no moisture sensitivity constraints. Components can be stored and handled without special humidity control or baking procedures prior to soldering.

Q: Which substitute part should I select if PCB space is limited?

A: C503B-AAN-CA0C0342-015 or C503B-AAN-CA0C0252-015 both offer reduced height (11.30mm) compared to the main part (13.30mm). Verify your specific clearance requirements before selection.
