Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSL-LXA228YC-TR21 is determined by strict alignment of the following critical parameters:

Mechanical Compatibility Parameters:

• Mounting Type: Surface Mount, Bottom Entry
• Package / Case: 2-SMD, Yoke Bend
• Supplier Device Package: Axial
• Size / Dimension: 2.50mm L x 2.00mm W
• Height (Max): 2.90mm
• Lens Style: Round with Domed Top
• Lens Size: 1.90mm Dia

Optical Parameters:

• Color: Yellow
• Lens Color: Colorless
• Lens Transparency: Clear
• Viewing Angle: 25°

Electrical Parameters:

• Voltage - Forward (Vf) (Typ): 2V
• Configuration: Standard

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 4 (72 Hours)
• REACH Status: REACH Unaffected

Substitute parts must maintain identical values across all mechanical, optical, and compliance parameters. Variations in brightness rating (millicandela) and peak wavelength within the yellow spectrum are permissible when the substitute part is active and available.

Parameter Comparison

Engineering Selection Recommendations

The SSL-LXA228SYC-TR21 is the manufacturer-recommended substitute for the obsolete SSL-LXA228YC-TR21. Both components are manufactured by Lumex Opto/Components Inc. and share identical mechanical, optical, and compliance specifications.

The substitute part maintains full compatibility with existing PCB layouts, assembly processes, and mounting requirements. Both parts are ROHS3 compliant and REACH unaffected, satisfying regulatory requirements for current production environments.

The SSL-LXA228SYC-TR21 is currently active in the product portfolio with 800 units in stock, ensuring supply chain continuity. The increased brightness rating (300mcd versus 30mcd) and minor peak wavelength shift (590nm versus 585nm) remain within the yellow LED specification range and do not compromise functional compatibility in standard indication applications.

Frequently Asked Questions (FAQ)

Q: Can the SSL-LXA228SYC-TR21 be used as a direct replacement for the SSL-LXA228YC-TR21?

A: Yes. The SSL-LXA228SYC-TR21 maintains identical mechanical dimensions, mounting configuration, electrical forward voltage, and optical characteristics. No PCB modifications or assembly process changes are required.

Q: What is the difference in brightness between the main part and the substitute?

A: The SSL-LXA228YC-TR21 operates at 30mcd, while the SSL-LXA228SYC-TR21 operates at 300mcd. The substitute provides 10 times greater luminous intensity. Circuit current limiting resistors may require adjustment to maintain equivalent brightness levels in the application.

Q: Are there differences in wavelength between these parts?

A: The main part has a peak wavelength of 585nm, while the substitute has a peak wavelength of 590nm. Both values fall within the yellow LED spectrum and are visually indistinguishable in standard indication applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SSL-LXA228YC-TR21 and SSL-LXA228SYC-TR21 are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 4, 72 Hours).

Q: What is the mounting orientation for these components?

A: Both parts are surface mount devices with bottom entry configuration, 2-SMD yoke bend package. The physical dimensions are 2.50mm length x 2.00mm width with a maximum height of 2.90mm.

Q: Why is the main part listed as obsolete?

A: The SSL-LXA228YC-TR21 has been discontinued by the manufacturer. The SSL-LXA228SYC-TR21 is the active replacement offering equivalent functionality with improved brightness characteristics.
