SSL-LX3353YD Yellow LED Equivalent & Substitute Parts

Part Overview

The SSL-LX3353YD is an active yellow LED indication component manufactured by Lumex Opto/Components Inc., designed for through-hole mounting applications. This diffused square-type LED operates at 2.1V forward voltage with a 10mcd brightness rating and 80° viewing angle, suitable for standard indicator applications requiring discrete yellow light emission at 585nm peak wavelength.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or inventory depletion. The SSL-LX3353YD maintains ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), making it suitable for general industrial and commercial applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SSL-LX3353YD is determined by strict alignment with the following critical parameters:

Primary Compatibility Criteria:

• Color: Yellow (visual indication function)
• Lens Transparency: Diffused (optical characteristic)
• Lens Size: 3.00mm (physical footprint)
• Mounting Type: Through Hole (assembly compatibility)
• Lens Style: Square with Flat Top (mechanical fit)
• Forward Voltage (Vf): 2.0V to 2.2V range (circuit compatibility)
• Current Rating: 20mA standard test condition
• RoHS3 Compliance: Required for regulatory alignment

Secondary Consideration Parameters:

• Millicandela Rating: Brightness may vary; higher ratings acceptable if circuit design permits
• Viewing Angle: May exceed 80° without functional degradation
• Peak Wavelength: Yellow spectrum range (580nm to 595nm acceptable)

The XSMYK43MB from SunLED meets all primary compatibility criteria and qualifies as a direct substitute based on matching physical dimensions, mounting type, lens configuration, and regulatory compliance.

Engineering Selection Recommendations

SSL-LX3353YD (Primary Component):

• Select when Lumex supply chain availability is confirmed
• Maintains exact specification match for brightness (10mcd) and viewing angle (80°)
• ROHS3 compliant with unlimited MSL rating suitable for standard storage conditions
• Active product status ensures continued availability

XSMYK43MB (Substitute Component):

• Select when SSL-LX3353YD supply is unavailable or lead times exceed project requirements
• Meets all critical physical and electrical compatibility parameters
• Forward voltage differential (2.0V vs 2.1V) falls within standard circuit tolerance ranges
• Exceeds brightness specification (98mcd vs 10mcd) and viewing angle (110° vs 80°); these enhancements do not create functional incompatibility
• ROHS3 compliance and unlimited MSL rating match primary component
• Active product status with higher inventory availability (14,527 pcs vs 889 pcs) provides supply security
• Ice Cube series designation indicates enhanced optical performance characteristics

Both components are suitable for direct substitution in through-hole yellow LED indication circuits operating at 20mA test current with forward voltage requirements in the 2.0V to 2.1V range.

Frequently Asked Questions (FAQ)

Q: Can XSMYK43MB replace SSL-LX3353YD in existing PCB designs without modification?

A: Yes. Both components share identical lens size (3.00mm), lens style (square with flat top), mounting type (through hole), and radial package configuration. No PCB layout changes are required. The 0.2mm height difference (4.80mm vs 4.60mm) is within standard mechanical tolerance for through-hole assembly.

Q: What is the impact of the brightness difference (98mcd vs 10mcd)?

A: The XSMYK43MB provides significantly higher brightness. In applications where the original 10mcd specification was selected for specific visibility requirements, the substitute's 98mcd output will produce a brighter indication. Circuit design must accommodate this if brightness control is critical; however, standard current-limiting resistor adjustment can reduce perceived brightness if necessary.

Q: Are the forward voltage specifications compatible?

A: Yes. The 0.1V difference (2.1V vs 2.0V) is within standard engineering tolerance for LED circuit design. Most current-limiting resistor calculations accommodate ±0.1V variation in forward voltage without functional impact.

Q: Does the 110° viewing angle of XSMYK43MB create compatibility issues?

A: No. The wider viewing angle (110° vs 80°) expands the visibility range without creating incompatibility. Applications designed for 80° viewing angle will function correctly with the broader 110° specification.

Q: Are both components RoHS3 compliant?

A: Yes. Both SSL-LX3353YD and XSMYK43MB carry ROHS3 compliance certification, meeting current regulatory requirements for hazardous substance restrictions.

Q: What is the wavelength difference between 585nm and 590nm?

A: Both wavelengths fall within the yellow spectrum range. The 5nm difference is imperceptible to human vision and does not affect functional compatibility in yellow LED indication applications.

Q: Which component should be selected for new designs?

A: Selection depends on supply availability and project requirements. For new designs, either component is acceptable based on inventory status and lead time considerations. XSMYK43MB offers higher brightness and wider viewing angle as standard features.

Q: Are moisture sensitivity ratings identical?

A: Yes. Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
