LED XLAMP Warm White 2850K XPEBWT-L1-0000-00AF8 Equivalent & Substitute Parts

Part Overview

The XPEBWT-L1-0000-00AF8 is an XLamp® XP-E2 warm white LED from CreeLED, Inc., designed for general illumination applications requiring warm color temperature lighting. This surface mount LED operates at 2850K color temperature with a typical forward voltage of 2.9V and 350mA test current, delivering 91 lumens at 85°C. The component is currently active in production and maintains full RoHS compliance and REACH unaffected status. Identifying equivalent substitute parts is necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits alternative warm white LED options within compatible electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the XPEBWT-L1-0000-00AF8 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Warm white color category (2200K–2850K CCT range)
• Surface mount technology with 1414 (3535 Metric) package footprint
• Forward voltage within 2.85V–2.9V range to ensure circuit compatibility
• Test current at or near 350mA nominal operation
• CRI of 80 or higher for color rendering consistency
• RoHS compliant and REACH unaffected status

Allowable Variation Parameters:

• Viewing angle: 110°–115° (minor optical field differences acceptable)
• Flux output: 87–94 lm range at 85°C (within specified tolerance band)
• Maximum current rating: 1A–1.5A (higher ratings provide design margin)
• Thermal resistance: 5°C/W–9°C/W (lower values indicate improved thermal performance)
• Height seated: 2.39–2.54mm (within PCB assembly clearance tolerance)

The substitute part XTEAWT-00-0000-00000LAEA meets all mandatory criteria while offering improved thermal characteristics and higher maximum current rating.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (XPEBWT-L1-0000-00AF8): Select the primary part when CCT specification of 2850K is a critical design requirement and when thermal management is not a limiting factor in the application. This part maintains active production status with full RoHS compliance and REACH unaffected designation, ensuring long-term supply stability and regulatory compliance.

Substitute Part Selection (XTEAWT-00-0000-00000LAEA): The XTEAWT-00-0000-00000LAEA is a valid substitute when the primary part is unavailable or when design requirements permit a warmer color temperature (2200K). This substitute offers measurable advantages: superior thermal resistance (5°C/W versus 9°C/W), higher maximum current rating (1.5A versus 1A), and marginally improved efficiency (91 lm/W versus 90 lm/W). Both parts maintain identical RoHS compliance and REACH unaffected status. The 0.15mm height difference and 5° wider viewing angle fall within standard PCB assembly tolerances and do not introduce compatibility issues.

Compliance Assurance: Both parts are RoHS compliant and REACH unaffected, meeting regulatory requirements for electronic component use in regulated markets. Active production status for both parts ensures continued availability and consistent quality.

Frequently Asked Questions (FAQ)

Q: Can XTEAWT-00-0000-00000LAEA directly replace XPEBWT-L1-0000-00AF8 on existing PCBs?

A: Yes. Both parts use identical 1414 (3535 Metric) surface mount packages with matching 3.45mm × 3.45mm footprints. The 0.15mm height difference (2.54mm versus 2.39mm) remains within standard PCB assembly clearance specifications. No PCB redesign is required.

Q: What is the color temperature difference between these parts?

A: The primary part operates at 2850K (neutral warm white), while the substitute operates at 2200K (deeper warm white). Both fall within the warm white category. Applications requiring precise 2850K specification should use the primary part. Applications tolerant of warmer tones can use the substitute.

Q: Are there electrical circuit compatibility concerns?

A: No. Forward voltage differs by only 0.05V (2.9V versus 2.85V), which is negligible in typical LED driver circuits. Both parts operate at identical 350mA test current. The substitute's higher maximum current rating (1.5A versus 1A) provides additional design margin without affecting nominal operation.

Q: Does the substitute offer any performance advantages?

A: Yes. The substitute provides superior thermal resistance (5°C/W versus 9°C/W), resulting in lower junction temperatures under identical operating conditions. This thermal advantage extends component lifespan and improves reliability in thermally constrained applications. Luminous efficiency is marginally higher (91 lm/W versus 90 lm/W).

Q: Are both parts compliant with environmental regulations?

A: Yes. Both XPEBWT-L1-0000-00AF8 and XTEAWT-00-0000-00000LAEA are RoHS compliant and REACH unaffected, meeting regulatory requirements for electronic components in regulated markets.

Q: What is the viewing angle difference?

A: The primary part has a 110° viewing angle, while the substitute has a 115° viewing angle. This 5° difference represents a minor optical field expansion and does not introduce compatibility issues in typical lighting applications.

Q: Are both parts in active production?

A: Yes. Both parts maintain active production status, ensuring continued availability and consistent quality from CreeLED, Inc.
