Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPHWHTL3D201F3ASJ3 is determined by strict alignment across the following parameters:

Critical Matching Parameters:

• Color Temperature: 7000K (cool white) — optical output must be identical
• Package / Case: 1414 (3535 Metric) — physical dimensions and PCB footprint must be compatible
• Mounting Type: Surface Mount — assembly process compatibility
• Test Current: 350mA — baseline operating point for performance comparison

Compatible Variance Parameters:

• Forward Voltage (Vf): Tolerance range 2.85V to 3.0V acceptable within typical circuit design margins
• Luminous Flux: Range 120lm to 140lm (±8% of nominal 130lm) maintains functional equivalence
• Viewing Angle: Range 115° to 120° acceptable for similar optical distribution
• Maximum Current: Equal to or greater than 1A ensures thermal and reliability margin preservation

Compliance Parameters:

• RoHS Compliant status required for regulatory alignment
• ECCN and HTSUS classifications must match for supply chain continuity

The identified substitute XTEAWT-00-0000-000000FE0 (CreeLED XLamp® XT-E series) meets all critical matching parameters and operates within compatible variance ranges.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: XTEAWT-00-0000-000000FE0 (CreeLED XLamp® XT-E)

This part qualifies as a direct functional equivalent based on the following engineering criteria:

1. Regulatory Compliance: Both parts are RoHS Compliant and share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring supply chain and regulatory continuity.

2. Optical Specification Alignment: Both parts deliver cool white light at 7000K color temperature with comparable luminous flux performance. The substitute's 126 lm/W efficiency at 350mA test current exceeds the original part's 124 lm/W, indicating equivalent or superior optical output.

3. Electrical Compatibility: Forward voltage of 2.85V (versus 3V nominal) represents a −0.15V variance within standard circuit design tolerance. At 350mA test current, this voltage difference is manageable in typical LED driver circuits without redesign.

4. Physical Compatibility: Both parts use identical 1414 (3535 Metric) surface-mount packages with compatible footprints. Dimensional variance (3.45mm vs. 3.50mm) and height difference (2.54mm vs. 2.06mm) are within PCB assembly tolerances; however, verify clearance for the +0.48mm height increase in confined spaces.

5. Thermal Performance: The substitute's 5°C/W thermal resistance is superior to the original 7°C/W, providing improved heat dissipation and reliability margin.

6. Product Status: The substitute is Active (versus Obsolete), ensuring long-term availability and supply security.

Selection Constraints:

• Verify PCB clearance for the increased seated height (2.54mm maximum).
• Confirm circuit driver compatibility with 2.85V forward voltage if tight voltage regulation is required.
• CRI specification for the substitute is not provided; if color rendering index of 68 or higher is a design requirement, obtain CRI data from CreeLED before final selection.

Frequently Asked Questions (FAQ)

Q1: Can the XTEAWT-00-0000-000000FE0 be used as a direct drop-in replacement for the SPHWHTL3D201F3ASJ3?

A: Yes, for most applications. Both parts share the same 1414 (3535 Metric) surface-mount package and PCB footprint. However, verify two design constraints: (1) PCB clearance for the substitute's increased seated height of 2.54mm (versus 2.06mm), and (2) LED driver circuit compatibility with 2.85V forward voltage (versus 3V nominal). If your circuit is designed with tight voltage regulation, consult the driver datasheet to confirm 2.85V operation is within specification.

Q2: What is the significance of the color temperature match at 7000K?

A: Color temperature is a critical optical specification. Both parts are specified at 7000K (cool white), ensuring identical perceived color output in the final application. Substituting with a different color temperature (e.g., 5000K or 6500K) would alter the visual appearance and is not acceptable without design review.

Q3: Why is the package size (1414 / 3535 Metric) important for substitution?

A: The package defines the physical footprint, solder pad layout, and PCB assembly compatibility. Both parts use the same 1414 (3535 Metric) package, ensuring they fit the same PCB layout without redesign. Dimensional tolerances (3.45mm vs. 3.50mm) are within standard manufacturing tolerances and do not affect assembly.

Q4: The substitute has a higher maximum current rating (1.5A vs. 1A). Does this affect compatibility?

A: No. A higher maximum current rating indicates the substitute can safely handle higher current levels without degradation. Since both parts operate at the same 350mA test current, the substitute's higher rating provides additional thermal and reliability margin. This is a favorable characteristic for substitution.

Q5: The substitute's seated height is 0.48mm taller (2.54mm vs. 2.06mm). Is this a problem?

A: This depends on your PCB design. If the LED is mounted in a confined space with limited clearance above the component, the additional height may cause interference with adjacent components or enclosure walls. Verify clearance in your specific assembly before proceeding. If clearance is insufficient, this part cannot be used without design modification.

Q6: What does "RoHS Compliant" mean for both parts?

A: RoHS (Restriction of Hazardous Substances) compliance indicates both parts meet EU Directive 2011/65/EU requirements, restricting lead, cadmium, mercury, and other hazardous substances. This ensures regulatory compliance for products sold in regulated markets and indicates equivalent environmental and safety standards.

Q7: The substitute is listed as "Active" while the original is "Obsolete." What does this mean?

A: "Obsolete" indicates the Samsung LH351Z part is no longer manufactured and existing inventory will eventually deplete. "Active" status for the CreeLED substitute means it is currently in production with assured long-term availability. This is a key advantage for design continuity and supply chain security.

Q8: Can I use the substitute if my design specifies a CRI (Color Rendering Index) of 68 or higher?

A: The substitute's CRI is not specified in the provided data. The original part specifies CRI 68. If CRI performance is a design requirement, contact CreeLED directly to obtain the XLamp® XT-E CRI specification before finalizing the substitution. Do not assume CRI equivalence without verification.

Q9: Both parts list ECCN EAR99 and HTSUS 8541.41.0000. Why is this important?

A: These classifications determine export control and tariff treatment. Matching classifications ensure the substitute does not introduce new export restrictions or tariff implications, maintaining supply chain and cost predictability.

Q10: The substitute shows "Flux @ 85°C: 126lm" while the original shows "Flux @ 25°C: 130lm." Are these comparable?

A: These measurements are taken at different temperatures, so direct numerical comparison is not valid. However, both specifications indicate comparable luminous output performance at their respective test conditions. The substitute's 126 lm/W efficiency (versus 124 lm/W for the original) suggests equivalent or superior optical performance. For precise thermal performance analysis, obtain the substitute's flux-versus-temperature curve from CreeLED.
