LED LUXEON Q L1Q0-4070000001100 Equivalent & Substitute Parts

Part Overview

The L1Q0-4070000001100 is a LUXEON Q series white neutral LED (4000K) in a 3535 metric package designed for surface mount applications. This component is classified as obsolete, necessitating identification of active equivalent parts that maintain functional compatibility for new designs or production continuity. Substitute parts must preserve the neutral white color temperature, surface mount capability, and thermal characteristics required for the original application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Color temperature: 4000K neutral white (mandatory match)
• Mounting type: Surface mount (mandatory match)
• Forward voltage (Vf): Range 2.8V to 2.99V (acceptable tolerance for circuit compatibility)
• CRI: 70 or higher (maintains color rendering performance)
• RoHS compliance: ROHS3 or equivalent (regulatory requirement)
• Product status: Active (ensures ongoing availability)

The two substitute parts meet these criteria while offering improved efficiency, thermal performance, or expanded availability compared to the obsolete L1Q0-4070000001100.

Parameter Comparison

Engineering Selection Recommendations

L1T2-4070000000000 (LUXEON TX): This Lumileds substitute offers the highest efficiency at 137 lm/W and superior thermal performance (3°C/W), making it suitable for applications requiring reduced power dissipation. The active product status ensures long-term availability. The 2-SMD package differs from the original 1414 metric package, requiring PCB layout verification. Forward voltage tolerance (2.8V) is within acceptable circuit operating range.

XPEBWT-01-0000-00DE5 (XLamp® XP-E2): This CreeLED substitute maintains identical footprint compatibility (1414/3535 metric package) with the original part, simplifying PCB redesign requirements. RoHS compliance is confirmed. The lower flux output (111 lm at 350mA test current) and higher thermal resistance (9°C/W) indicate this substitute is suitable for lower-intensity applications. Forward voltage (2.9V) closely matches the original specification.

Both substitutes maintain 4000K neutral white color temperature, 70 CRI, and surface mount capability. Selection depends on thermal budget, flux requirements, and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can L1T2-4070000000000 be used as a direct replacement without PCB modification?

A: The L1T2-4070000000000 uses a 2-SMD package versus the original 1414 metric package. PCB footprint and land pattern verification is required. Forward voltage (2.8V) is compatible with circuits designed for 2.99V operation.

Q: What are the thermal implications of selecting XPEBWT-01-0000-00DE5?

A: The XPEBWT-01-0000-00DE5 has thermal resistance of 9°C/W compared to the original 7°C/W. In applications with thermal constraints, this substitute generates higher junction temperatures at equivalent power levels. Thermal management design review is necessary.

Q: Are both substitutes suitable for 1A operation?

A: L1T2-4070000000000 supports maximum current of 1.5A. XPEBWT-01-0000-00DE5 supports maximum current of 1A. Both can operate at the original 1A test current, though at different flux outputs due to their respective efficiency ratings.

Q: Do the substitutes maintain color consistency with the original part?

A: Both substitutes specify 4000K neutral white with 70 CRI, matching the original color temperature and rendering index. The original part specifies 3-Step MacAdam Ellipse tolerance; substitute MacAdam specifications are not provided in the data.

Q: What is the inventory status of these substitutes?

A: L1T2-4070000000000 has 6839 pieces in stock. XPEBWT-01-0000-00DE5 has 1094 pieces in stock. Both are classified as active products with ongoing manufacturer support.
