Substitute Part Grouping Explanation
Substitute parts for the SSF-LXH103UWW are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:
Critical Parameters (Must Match Exactly):
- Voltage Rating: 3.6V
- Current Rating: 20mA
- Wavelength - Peak: 550nm (white color)
- Configuration: Single LED
- Mounting Type: Through Hole, Right Angle
Compatible Variation Parameters (May Differ Within Acceptable Range):
- Millicandela Rating: Higher values are acceptable as they represent increased brightness while maintaining the same electrical characteristics
- Viewing Angle: Variations are acceptable as they represent different light distribution patterns suitable for different application requirements
- Lens Type: Diffused, White designation remains consistent
Compliance Parameters (Must Maintain or Exceed):
- RoHS Status: ROHS3 Compliant or equivalent
- Moisture Sensitivity Level: MSL 1 (Unlimited)
- REACH Status: REACH Unaffected
The SSF-LXH103UWC qualifies as a direct substitute because it maintains all critical electrical parameters while offering enhanced brightness (1200mcd vs. 500mcd) and a slightly wider viewing angle (34° vs. 30°), providing performance improvements without compromising circuit compatibility.

Engineering Selection Recommendations
Primary Selection - SSF-LXH103UWW: Select this part when the original design specification requires exactly 500mcd brightness and 30° viewing angle. This part is Active and maintains full ROHS3 compliance with MSL 1 rating, suitable for standard production applications.
Substitute Selection - SSF-LXH103UWC: Select this part when enhanced brightness (1200mcd) and wider viewing angle (34°) are acceptable or beneficial for the application. Both parts share identical electrical ratings (3.6V, 20mA), mounting configuration (through-hole, right-angle), and wavelength (550nm white). The SSF-LXH103UWC maintains Active product status and identical compliance certifications (ROHS3, REACH Unaffected, MSL 1). This substitute is appropriate for applications where increased luminous intensity improves visibility without circuit redesign.
Compliance Verification: Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory compatibility in current production environments. MSL 1 rating on both parts indicates unlimited moisture sensitivity protection, suitable for standard storage and handling conditions.
Frequently Asked Questions (FAQ)
Q: Can SSF-LXH103UWC replace SSF-LXH103UWW in existing circuit designs?
A: Yes. Both parts operate at identical electrical specifications (3.6V, 20mA) and share the same mounting configuration (through-hole, right-angle). The SSF-LXH103UWC provides higher brightness (1200mcd vs. 500mcd) and wider viewing angle (34° vs. 30°), which are performance enhancements that do not require circuit modification.
Q: What is the difference between the lens descriptions "Diffused, White" and "Water Clear"?
A: Both parts feature diffused white lenses. The "Water Clear" designation in the SSF-LXH103UWC description refers to the lens material clarity, which contributes to the higher millicandela rating. Both maintain the same diffused white optical characteristics for the specified wavelength (550nm).
Q: Are there packaging differences between these parts?
A: The SSF-LXH103UWW is specified with "-" packaging notation, while the SSF-LXH103UWC is supplied in Bulk packaging. Both are through-hole components suitable for PCB assembly. Verify packaging requirements with your procurement process.
Q: Do both parts meet the same compliance standards?
A: Yes. Both SSF-LXH103UWW and SSF-LXH103UWC are ROHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. They meet identical regulatory requirements for current production applications.
Q: Which part should I select if brightness is critical to the application?
A: Select SSF-LXH103UWC. It provides 1200mcd compared to 500mcd on the SSF-LXH103UWW, delivering 2.4 times greater luminous intensity while maintaining all other electrical and mechanical specifications.
Q: Can I use SSF-LXH103UWW as a substitute for SSF-LXH103UWC?
A: No. While both parts are electrically compatible, the SSF-LXH103UWW provides lower brightness (500mcd vs. 1200mcd). Substitution in the reverse direction would reduce luminous intensity and may not meet application visibility requirements.
Q: What is the significance of the base product number SSF-LXH103?
A: The base product number SSF-LXH103 indicates that both parts belong to the same product family and share the same core mechanical and electrical platform. Variations in the full part number (UWW vs. UWC) reflect specific performance and packaging differences within this family.
