LED LUXEON TX Warm White 3000K 2-SMD L1T2-3070000002500 Equivalent & Substitute Parts

Part Overview

The L1T2-3070000002500 is a LUXEON TX series warm white LED (3000K) in a 2-SMD surface mount package with no lead exposed pad. This component is discontinued at DiGi Electronics but remains available in inventory. Finding equivalent and substitute parts is necessary due to product discontinuation and to ensure supply chain continuity for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution eligibility for the L1T2-3070000002500 is determined by the following critical parameters:

• Manufacturer & Series: Lumileds LUXEON TX
• Color & CCT: White, Warm 3000K
• Optical Performance: Flux output at 85°C and 700mA test current
• Electrical Characteristics: Forward voltage (2.8V), test current (700mA), maximum current rating
• Mechanical Compatibility: 2-SMD package, 3.70mm x 3.70mm footprint, 2.12mm maximum height, no lead exposed pad
• Compliance: ROHS3, MSL 1, REACH Unaffected

The substitute parts listed maintain these core parameters within acceptable engineering tolerances, ensuring direct functional and mechanical compatibility in existing designs.

Parameter Comparison

Engineering Selection Recommendations

L1T2-3070000002600 is the primary direct substitute. It is currently active in production, available in Tape & Reel packaging for volume applications, and includes 3-Step MacAdam Ellipse color binning for tighter color consistency. Maximum current rating is 1.2A compared to 1.5A in the main part; verify this does not exceed your circuit design limits. Flux output is marginally higher at 247 lm versus 245 lm.

L1T2-3070000000000 is a parametric equivalent with identical electrical and optical performance to the main part, including the same 1.5A maximum current rating. It is also active and available in Tape & Reel packaging. This part lacks the 3-Step MacAdam Ellipse color specification of the L1T2-3070000002600.

Both substitutes maintain full ROHS3 compliance, MSL 1 rating, and identical mechanical footprints. Selection between them depends on packaging requirements (Cut Tape versus Tape & Reel) and color consistency specifications for your application.

Frequently Asked Questions (FAQ)

Q: Can L1T2-3070000002600 replace L1T2-3070000002500 in existing designs?

A: Yes. Both parts share identical electrical characteristics (2.8V forward voltage, 700mA test current), optical performance (245–247 lm at 85°C), mechanical footprint (3.70mm x 3.70mm, 2.12mm height), and package type (2-SMD, no lead exposed pad). The primary difference is packaging format (Tape & Reel versus Cut Tape) and the addition of 3-Step MacAdam Ellipse color binning in the L1T2-3070000002600.

Q: What is the significance of 3-Step MacAdam Ellipse in the L1T2-3070000002600?

A: 3-Step MacAdam Ellipse is a color consistency specification that tightens the tolerance on color point variation. This ensures more uniform color output across production batches. If your application requires strict color matching, the L1T2-3070000002600 provides this additional specification.

Q: Are there differences in maximum current ratings between the substitutes?

A: Yes. The L1T2-3070000002600 has a maximum current rating of 1.2A, while both the L1T2-3070000002500 and L1T2-3070000000000 are rated for 1.5A. If your circuit operates at currents above 1.2A, use L1T2-3070000000000 or the original part.

Q: What packaging formats are available?

A: The L1T2-3070000002500 is supplied in Cut Tape (CT) format. Both substitutes, L1T2-3070000002600 and L1T2-3070000000000, are supplied in Tape & Reel (TR) format, which is standard for high-volume manufacturing.

Q: Are all parts RoHS3 compliant?

A: Yes. All three parts—L1T2-3070000002500, L1T2-3070000002600, and L1T2-3070000000000—are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.
