LED LUXEON Q L1Q0-4070000001400 Equivalent & Substitute Parts

Part Overview

The L1Q0-4070000001400 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, forward voltage characteristics, and thermal performance within acceptable engineering tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory parameters:

• Color and correlated color temperature (CCT): White, Neutral 4000K
• CRI (Color Rendering Index): 70
• RoHS and REACH compliance status
• Surface mount mounting type
• Forward voltage range: 2.72V to 2.8V (within ±3% of 2.81V nominal)
• Test current compatibility: 350mA nominal operation
• Thermal resistance: ≤7°C/W

Two active substitute parts meet these criteria: the LUXEON TX series L1T2-4070000000000 (Lumileds) and the XLamp XP-G2 series XPGBWT-01-0000-00GE5 (CreeLED). Both maintain the specified color temperature, CRI, compliance certifications, and electrical characteristics within acceptable tolerances for direct substitution in surface mount applications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing support and full compliance certifications (RoHS and REACH). The L1T2-4070000000000 (LUXEON TX) offers superior thermal performance (3°C/W versus 7°C/W) and higher luminous efficacy (137 lm/W), making it suitable for applications requiring enhanced heat dissipation and efficiency. The XPGBWT-01-0000-00GE5 (XLamp XP-G2) maintains identical package dimensions (3535 metric) and test current (350mA) to the original part, providing direct electrical and mechanical compatibility with minimal circuit redesign.

Selection between substitutes depends on application requirements: thermal management priorities favor the LUXEON TX, while mechanical and electrical compatibility with existing designs favor the XLamp XP-G2.

Frequently Asked Questions (FAQ)

Q: Can L1T2-4070000000000 be used as a direct replacement in existing PCB layouts?

A: The L1T2-4070000000000 uses a 2-SMD package configuration versus the original 1414 (3535 Metric) package. PCB footprint modification is required. However, electrical parameters (color temperature, CRI, forward voltage, compliance) are compatible.

Q: What is the primary difference between the two substitute parts?

A: The L1T2-4070000000000 operates at 700mA test current with 269lm output, while the XPGBWT-01-0000-00GE5 operates at 350mA test current with 135lm output. The LUXEON TX provides higher luminous output; the XLamp XP-G2 maintains the original test current specification.

Q: Are both substitutes suitable for 350mA operation?

A: Yes. Both parts are rated for maximum currents exceeding 1.05A (original specification). Operation at 350mA is within safe limits for both substitutes, though the L1T2-4070000000000 will operate below its rated test current.

Q: Do the substitutes maintain the same thermal characteristics?

A: No. Both substitutes have lower thermal resistance (3°C/W and 4°C/W respectively) compared to the original 7°C/W, resulting in improved heat dissipation. This is advantageous for thermal management.

Q: Are there viewing angle differences that affect application suitability?

A: Yes. The original part specifies 135° viewing angle. The L1T2-4070000000000 provides 160° (wider), and the XPGBWT-01-0000-00GE5 provides 115° (narrower). Application optics and beam distribution requirements should guide selection.
