Engineering Selection Recommendations

L1T2-4070000000000 (Lumileds LUXEON TX) Primary recommendation for direct replacement. Maintains 4000K neutral white CCT and identical RoHS3 compliance. Forward voltage and package compatibility confirmed. Higher efficiency (137 lm/W) and improved thermal resistance (3°C/W) provide performance enhancement. Package form factor differs (2-SMD vs. 1414), requiring PCB layout verification. Active product status ensures long-term availability.

XPGBWT-01-0000-00FE5 (CreeLED XLamp® XP-G2) Compatible substitute for 350mA operation at 4000K neutral white. Identical 1414 package and 3.45mm footprint. Forward voltage (2.72V) within acceptable range. Efficiency (133 lm/W) exceeds original specification. Thermal resistance (4°C/W) superior to main part. RoHS compliant. Active product status. Viewing angle reduced to 115° from 135°; verify optical requirements.

XTEAWT-00-0000-000000EE4 (CreeLED XLamp® XT-E, 4500K) Neutral white substitute with 4500K CCT within acceptable tolerance. Identical 1414 package and 350mA test current. Forward voltage (2.85V) compatible. Thermal resistance (5°C/W) acceptable. RoHS compliant. Active product status. Flux output (118 lm) slightly lower; efficiency (118 lm/W) reduced. Suitable for applications tolerating minor CCT shift.

XTEAWT-00-0000-000000HF4 (CreeLED XLamp® XT-E, 4750K) Neutral white substitute with 4750K CCT within acceptable tolerance. Identical 1414 package and 350mA test current. Forward voltage (2.85V) compatible. Thermal resistance (5°C/W) acceptable. RoHS compliant. Active product status. Flux output (144 lm) and efficiency (144 lm/W) exceed original specification.

Frequently Asked Questions (FAQ)

Q: Can the L1T2-4070000000000 replace the L1Q0-4070000001300 directly on the PCB? A: Electrical compatibility is confirmed (4000K, 2.8V forward voltage, RoHS3 compliant). However, the L1T2 uses a 2-SMD package with different footprint dimensions (3.70mm vs. 3.45mm). PCB layout and solder pad geometry must be verified before implementation. Consult package datasheets for exact pad spacing and reflow profile compatibility.

Q: What is the significance of the 1414 (3535 Metric) package specification? A: The 1414 designation refers to a 3.45mm × 3.45mm surface-mount LED package. This footprint is standard across multiple substitute options (XPGBWT, XTEAWT, XPLAWT series), ensuring mechanical compatibility with existing PCB designs. The L1T2-4070000000000 uses a different 2-SMD package (3.70mm × 3.70mm) and requires layout modification.

Q: Are there thermal management differences between the main part and substitutes? A: Yes. The L1Q0 has 7°C/W thermal resistance. Substitutes range from 2.5°C/W (XPLAWT series) to 5°C/W (XTEAWT series). Lower thermal resistance indicates superior heat dissipation. Applications with tight thermal budgets benefit from substitutes with improved thermal performance. Conversely, designs with adequate thermal margin may not require thermal performance upgrades.

Q: Can I use a 5000K or 6500K substitute if the application requires 4000K? A: No. Color temperature (CCT) is a critical optical parameter. The main part specifies 4000K neutral white. Substitutes with 5000K (cool white) or 6500K (daylight) produce visibly different color output unsuitable for applications requiring neutral white illumination. Use only substitutes within the 4000K ±500K tolerance range: L1T2-4070000000000 (4000K), XPGBWT-01-0000-00FE5 (4000K), XTEAWT-00-0000-000000EE4 (4500K), or XTEAWT-00-0000-000000HF4 (4750K).

Q: What does "Product Status: Obsolete" mean for the main part? A: Obsolete status indicates the L1Q0-4070000001300 is no longer manufactured by Lumileds and will not be restocked. Existing inventory (803 pcs noted) represents remaining stock only. New designs must transition to active substitute parts. All recommended substitutes carry "Active" product status, ensuring continued availability and manufacturing support.

Q: How do I determine which substitute is best for my application? A: Prioritize based on: (1) Package compatibility (1414 preferred for direct PCB fit), (2) CCT requirement (4000K ±500K for neutral white), (3) Current rating (350mA nominal for direct electrical compatibility), (4) Thermal requirements (lower thermal resistance for high-power applications). L1T2-4070000000000 and XPGBWT-01-0000-00FE5 are primary recommendations for 350mA operation. XPLAWT series supports higher current (1.05A) for increased brightness applications.

Q: Are all substitutes RoHS and REACH compliant? A: Yes. The main part (L1Q0) is ROHS3 compliant and REACH unaffected. All recommended substitutes maintain RoHS compliance (ROHS3 or RoHS) and REACH unaffected status, ensuring regulatory compatibility for EU and global markets.

Q: What is the impact of viewing angle differences? A: The main part has 135° viewing angle. Substitutes range from 115° (XPGBWT, XTEAWT series) to 160° (L1T2). Narrower viewing angles (115°) concentrate light output in a tighter beam; wider angles (160°) distribute light more broadly. Application optics and beam pattern requirements determine acceptable viewing angle ranges. Verify optical design compatibility before substitution.
