Engineering Selection Recommendations

Primary Substitutes for 3000K Warm White Application:

For applications requiring warm white color temperature closest to the original 3000K specification, XTEAWT-00-0000-00000HDF8 (2850K) and XTEAWT-00-0000-00000HDE8 (2700K) are the most appropriate selections. Both parts maintain identical package geometry (3535 metric), 115° viewing angle, 350mA test current, and 80 CRI rating. The 2850K variant provides the closest color temperature match with 111 lm flux output at 350mA.

Electrical Compatibility: All CreeLED XLamp XT-E substitutes operate at 2.85V forward voltage, representing a 0.05V reduction from the original 2.9V specification. This voltage differential is within typical LED circuit design tolerances and does not require circuit modification. Maximum current rating increases from 1A to 1.5A across all substitutes, providing enhanced current handling capability.

Thermal Performance: Substitute parts feature improved thermal resistance of 5°C/W compared to the original 7°C/W specification, indicating superior heat dissipation characteristics. This enhancement supports higher reliability in thermal-constrained applications.

Mechanical Compatibility: Substitute parts measure 3.45mm x 3.45mm versus the original 3.50mm x 3.50mm footprint. This 0.05mm reduction per side remains within standard PCB pad tolerance specifications for 3535 metric packages. Seated height increases from 2.06mm to 2.54mm, requiring verification of available clearance in existing mechanical assemblies.

Compliance Status: All substitute parts are RoHS Compliant and carry Active product status, ensuring regulatory compliance and ongoing manufacturing support. REACH status is listed as REACH Unaffected for all CreeLED substitutes.

Alternative Color Temperature Options: For applications permitting color temperature variation, the complete XLamp XT-E series provides options from 2200K to 6500K. XTEAWT-00-0000-000000EE4 (4500K neutral white) and XTEAWT-00-0000-00000BHE1 (6500K cool white) deliver higher flux output at 118 lm and 144 lm respectively, supporting brightness-critical applications.

Frequently Asked Questions (FAQ)

Q: Can XTEAWT-00-0000-00000HDF8 (2850K) be used as a direct replacement for SPHWHTL3D20EE3VPF3 (3000K)?

A: Yes. Both parts share identical package (3535 metric), mounting type (surface mount), viewing angle (115°), test current (350mA), and CRI rating (80). The 150K color temperature difference (3000K to 2850K) falls within warm white classification. Forward voltage differs by 0.05V (2.9V to 2.85V), which is acceptable in standard LED circuit designs. Mechanical clearance must be verified due to 0.48mm increase in seated height (2.06mm to 2.54mm).

Q: What is the impact of the 0.05V forward voltage difference between the main part and substitutes?

A: The reduction from 2.9V to 2.85V represents a 1.7% decrease in forward voltage. In series LED circuits with current-limiting resistors, this voltage difference produces negligible impact on circuit operation. In constant-current driver circuits, no adjustment is required. Verify circuit design margins if operating near voltage supply limits.

Q: Are the dimensional differences between main part and substitutes critical?

A: Footprint dimensions reduce from 3.50mm to 3.45mm per side (0.05mm reduction), which is within standard PCB pad tolerance for 3535 metric packages and does not require PCB redesign. Seated height increases from 2.06mm to 2.54mm (0.48mm increase). This height difference must be evaluated against available clearance in mechanical assemblies, thermal management structures, and optical lens positioning.

Q: Which substitute part provides the closest performance match to the original LH351Z?

A: XTEAWT-00-0000-00000HDE8 (2700K) and XTEAWT-00-0000-00000HDF8 (2850K) provide the closest warm white color temperature match. XTEAWT-00-0000-00000HDF8 (2850K) is preferred for 3000K applications due to minimal color temperature offset (150K difference) and matching 80 CRI specification. Flux output of 111 lm at 350mA exceeds the original 100 lm specification by 11%, supporting brightness-equivalent or improved performance.

Q: What is the significance of improved thermal resistance in substitute parts?

A: Substitute parts feature 5°C/W thermal resistance versus 7°C/W in the original part, representing a 28.6% improvement in heat dissipation efficiency. This enhancement reduces junction temperature rise under identical operating conditions, supporting extended component lifetime and improved reliability in thermally constrained applications. No circuit modification is required to benefit from this improvement.

Q: Can substitute parts with different color temperatures (4500K, 6500K) be used in the same application?

A: Substitution with different color temperatures is application-dependent. All substitute parts maintain identical package, mounting, viewing angle, and test current specifications. Color temperature selection must align with application requirements. Neutral white (4500K) and cool white (6500K) options deliver higher flux output (118 lm to 144 lm) but produce different color appearance. Verify application tolerance for color temperature variation before implementation.

Q: What packaging options are available for substitute parts?

A: CreeLED XLamp XT-E substitutes are available in Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging formats. XTEAWT-00-0000-00000BGE2 (5700K) is available in Cut Tape & Digi-Reel® format with 1,000,000 pcs inventory. Other variants are supplied in Tape & Reel format. Packaging selection depends on production volume and assembly equipment compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. All CreeLED XLamp XT-E substitute parts listed are RoHS Compliant. The original Samsung LH351Z is also RoHS Compliant. No regulatory compliance issues exist for substitution.

Q: What is the maximum current rating difference between the main part and substitutes?

A: The original part is rated for 1A maximum current. All CreeLED XLamp XT-E substitutes are rated for 1.5A maximum current, representing a 50% increase in current handling capability. This enhanced rating provides design margin for applications requiring higher brightness or future performance upgrades. Existing circuits designed for 350mA operation require no modification.
