SSL-LXA1725YC-TR Yellow LED 2-SMD Equivalent & Substitute Parts

Part Overview

The SSL-LXA1725YC-TR is a yellow LED indication component manufactured by Lumex Opto/Components Inc., configured as a 2-SMD surface mount device with a clear, rectangular flat-top lens. This part operates at a forward voltage of 2.1V with a test current of 20mA and delivers 12 millicandela of luminous intensity at a peak wavelength of 585nm. The component is classified as obsolete, necessitating identification of active equivalent parts for ongoing production and procurement requirements. Substitute parts must maintain electrical compatibility, mechanical fit, and performance characteristics within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

The AA3022YC-4.5SF from Kingbright is a qualified substitute for the SSL-LXA1725YC-TR based on the following engineering criteria:

Electrical Equivalence: Both components operate at identical forward voltage (2.1V) and test current (20mA), ensuring direct circuit compatibility without modification to current-limiting resistor values or power supply specifications.

Mechanical Compatibility: Both parts share identical package configuration (2-SMD, Gull Wing), footprint dimensions (3.00mm L x 2.20mm W), and lens geometry (colorless, clear, rectangular flat-top). The AA3022YC-4.5SF height of 1.65mm exceeds the SSL-LXA1725YC-TR maximum of 1.50mm by 0.15mm, which remains within typical PCB assembly tolerances for surface mount components.

Regulatory Compliance: Both components maintain ROHS3 compliance and identical MSL rating of 4 (72 Hours), satisfying environmental and handling requirements for production environments.

Performance Enhancement: The AA3022YC-4.5SF delivers 15 millicandela versus 12 millicandela of the original part, providing increased luminous intensity. Peak wavelength shifts from 585nm to 590nm, remaining within the yellow spectrum range. Viewing angle reduces from 130° to 90°, which narrows the light distribution cone but maintains adequate visibility for standard indication applications.

Product Status: The AA3022YC-4.5SF carries active product status, ensuring long-term availability and supply chain continuity compared to the obsolete SSL-LXA1725YC-TR.

Frequently Asked Questions (FAQ)

Q: Can the AA3022YC-4.5SF be used as a direct replacement without PCB modifications?

A: Yes. Both components share identical electrical specifications (2.1V forward voltage, 20mA test current) and footprint dimensions (3.00mm L x 2.20mm W). No circuit modifications are required. The height difference of 0.15mm (1.65mm versus 1.50mm) is within standard surface mount assembly tolerances.

Q: How does the change in millicandela rating affect circuit performance?

A: The AA3022YC-4.5SF provides 15mcd compared to 12mcd of the original part, representing a 25% increase in luminous intensity. This enhancement improves visibility without requiring circuit modifications, as the forward voltage and test current remain identical.

Q: What is the impact of the 40nm wavelength shift from 585nm to 590nm?

A: Both wavelengths fall within the yellow spectrum range. The 590nm peak wavelength of the AA3022YC-4.5SF produces a slightly warmer yellow appearance compared to the 585nm of the SSL-LXA1725YC-TR. This difference is imperceptible in most indication applications and does not affect electrical compatibility.

Q: Why does the viewing angle decrease from 130° to 90°?

A: The AA3022YC-4.5SF has a narrower light distribution cone (90°) compared to the SSL-LXA1725YC-TR (130°). This concentrates luminous intensity in a more focused beam. For applications requiring wide-angle visibility, this characteristic must be evaluated against specific application requirements. The 90° viewing angle remains suitable for standard front-panel indication applications.

Q: Are there any handling or storage differences between these components?

A: Both components carry identical MSL rating of 4 (72 Hours), requiring identical moisture control procedures during storage and handling. No additional precautions are necessary when transitioning from SSL-LXA1725YC-TR to AA3022YC-4.5SF.

Q: Does the active product status of the AA3022YC-4.5SF provide supply advantages?

A: Yes. The AA3022YC-4.5SF maintains active product status with established supply channels, whereas the SSL-LXA1725YC-TR is classified as obsolete. Transitioning to the AA3022YC-4.5SF ensures long-term component availability and reduces supply chain risk for ongoing production requirements.
