Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C5SMF-AJS-CT0U0342 is determined by the following critical parameters:

• Color and Wavelength: Amber specification with dominant wavelength in the 590-591nm range
• Electrical Characteristics: Forward voltage of 2.1V and test current of 20mA
• Optical Properties: Clear lens transparency, oval domed lens style, 5.10mm x 3.70mm lens dimensions, and 100° x 40° viewing angle
• Mechanical Compatibility: Through-hole radial mounting, 5mm package form factor
• Environmental Compliance: MSL 1 rating, REACH unaffected status, EAR99 classification

Two active substitute parts meet these criteria:

1. C5SMF-AJF-CT0U0342: Direct manufacturer equivalent with identical electrical and optical specifications, differing only in packaging format and product status (active vs. obsolete).

2. C5SMF-AJF-CS0V0252: Parametric equivalent maintaining all critical electrical and mechanical parameters, with increased brightness rating (1885mcd vs. 1615mcd) and active product status.

Parameter Comparison

Engineering Selection Recommendations

C5SMF-AJF-CT0U0342 is the primary substitute for direct replacement applications. This part maintains identical electrical specifications (2.1V forward voltage, 20mA test current) and optical characteristics (1615mcd, 591nm wavelength) as the obsolete C5SMF-AJS-CT0U0342. The part is active in production with RoHS compliance certification and Tape & Box packaging availability. The 0.45mm reduction in maximum height (10.50mm vs. 10.95mm) is within typical mechanical tolerances for through-hole LED applications.

C5SMF-AJF-CS0V0252 serves as an alternative where increased brightness is acceptable or beneficial. This part provides 1885mcd brightness (270mcd higher than the original specification) while maintaining all critical electrical parameters and mechanical compatibility. The wavelength shift from 591nm to 590nm remains within the amber LED specification range. This option is suitable for applications where enhanced visibility is advantageous without circuit redesign.

Both substitutes carry identical environmental compliance ratings (MSL 1, REACH unaffected, EAR99 classification) and are manufactured by CreeLED, Inc. within the Screen Master® series.

Frequently Asked Questions (FAQ)

Q: Can C5SMF-AJF-CT0U0342 be used as a direct drop-in replacement for C5SMF-AJS-CT0U0342?

A: Yes. Both parts share identical electrical specifications (2.1V forward voltage, 20mA test current), optical properties (1615mcd, 591nm wavelength, clear amber lens), and mechanical mounting characteristics (through-hole radial, 5mm package). The 0.45mm height difference falls within standard PCB design tolerances.

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

A: C5SMF-AJF-CT0U0342 maintains exact brightness parity (1615mcd) with the original part. C5SMF-AJF-CS0V0252 provides increased brightness (1885mcd) while preserving all other electrical and mechanical parameters. Both operate at 2.1V forward voltage and 20mA test current.

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

A: The main part C5SMF-AJS-CT0U0342 uses standard packaging (not specified). C5SMF-AJF-CT0U0342 and C5SMF-AJF-CS0V0252 are supplied in Tape & Box (TB) format, which is standard for production environments and does not affect component functionality.

Q: Do the substitute parts meet the same compliance requirements?

A: Both substitute parts carry identical compliance certifications: MSL 1 (Unlimited), REACH unaffected, and EAR99 classification. Additionally, both substitutes are RoHS compliant, which is not specified for the original part.

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

A: The 1nm difference is within the amber LED specification range and is not perceptible to human vision. Both wavelengths produce identical amber color appearance in indicator applications.

Q: Which substitute should be selected for new designs?

A: C5SMF-AJF-CT0U0342 is recommended for direct replacement scenarios requiring exact brightness matching. C5SMF-AJF-CS0V0252 is suitable for new designs where enhanced brightness provides operational benefits without requiring circuit modifications.
