Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Samsung LH351Z SPHWHTL3D201F3PSJ3 are identified based on strict alignment of the following critical parameters:

Color Temperature Match: 6500K cool white specification ensures consistent color point across applications.

Luminous Flux Range: Substitute parts must deliver flux output within acceptable tolerance of 130 lumens at 25°C under 350mA test current (range: 120-140 lm acceptable).

Test Current Compatibility: 350mA nominal test current establishes the baseline for flux and efficiency measurements.

Forward Voltage Tolerance: Typical forward voltage must remain within practical circuit design margins (3.0V nominal, with 3.05V acceptable for 350mA operation).

Efficiency Specification: Lumens per watt rating at test current confirms comparable light output per unit power consumption.

Package Footprint: 1414 (3535 metric) surface mount package ensures mechanical and thermal interface compatibility with existing PCB designs.

Viewing Angle: 115-120° range maintains consistent beam distribution characteristics.

Thermal Resistance: Package thermal resistance values (7-9°C/W) ensure comparable thermal management performance.

Compliance Status: RoHS compliance and ECCN classification (EAR99) confirm regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: The CreeLED XLamp® XP-E XPEWHT-L1-0000-00FE1 is the qualified substitute for the obsolete Samsung LH351Z SPHWHTL3D201F3PSJ3.

Justification Based on Product Status: The Samsung LH351Z is classified as obsolete, making the active-status CreeLED XP-E the appropriate alternative for new procurement and ongoing production requirements.

Compliance Alignment: Both components carry identical RoHS compliance status, ECCN classification (EAR99), and HTSUS code (8541.41.0000), confirming regulatory and trade equivalence.

Electrical Compatibility: Forward voltage differential of 0.05V (3.0V vs. 3.05V) at 350mA test current remains within standard circuit design tolerances for LED driver circuits. Luminous flux output of 126 lm falls within the acceptable tolerance band of the original 130 lm specification.

Mechanical Compatibility: Both components utilize identical 1414 (3535 metric) surface mount package footprints. Physical dimension variance (3.50mm vs. 3.45mm) and height difference (2.06mm vs. 2.13mm) are negligible for standard PCB assembly processes and thermal interface applications.

Thermal Performance: Thermal resistance increase from 7°C/W to 9°C/W represents acceptable variance for equivalent thermal management in typical application environments.

Color Rendering: The substitute part delivers improved CRI of 70 (typical) compared to the original 68, providing enhanced color accuracy without performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the CreeLED XP-E XPEWHT-L1-0000-00FE1 be used as a direct replacement for the Samsung LH351Z SPHWHTL3D201F3PSJ3?

A: Yes. Both components share identical color temperature (6500K), test current (350mA), package type (1414/3535 metric), and compliance certifications. Electrical and mechanical parameters fall within acceptable substitution tolerances for surface mount LED applications.

Q: What is the flux output difference between these two parts?

A: The Samsung LH351Z delivers 130 lm at 25°C under 350mA test current. The CreeLED XP-E delivers 126 lm under identical conditions. This 4 lm difference (approximately 3%) is within standard manufacturing tolerance ranges and acceptable for equivalent performance classification.

Q: Are there any forward voltage considerations for circuit design?

A: The Samsung LH351Z operates at 3.0V typical, while the CreeLED XP-E operates at 3.05V typical. This 0.05V difference is negligible for standard LED driver circuits and does not require design modification. Both components operate within the same current range (350mA test, 1.0A maximum).

Q: Do the physical dimensions differ significantly?

A: Both components use the 1414 (3535 metric) package. The Samsung LH351Z measures 3.50 x 3.50 mm with 2.06 mm seated height. The CreeLED XP-E measures 3.45 x 3.45 mm with 2.13 mm seated height. These variations are within standard PCB assembly tolerances and do not affect mechanical compatibility or thermal interface performance.

Q: What is the thermal resistance difference, and does it matter?

A: The Samsung LH351Z has 7°C/W thermal resistance, while the CreeLED XP-E has 9°C/W. This 2°C/W increase represents acceptable variance for equivalent thermal management in standard applications. Both values support comparable heat dissipation performance in typical operating environments.

Q: Is the viewing angle difference significant?

A: The Samsung LH351Z has 120° viewing angle, while the CreeLED XP-E has 115° viewing angle. This 5° difference is negligible for most applications and does not affect functional equivalence for general illumination or indicator applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the Samsung LH351Z and CreeLED XP-E carry RoHS compliance certification, confirming equivalent regulatory status for restricted substance content.

Q: What is the inventory status for the substitute part?

A: The CreeLED XP-E XPEWHT-L1-0000-00FE1 is classified as active product status with 899 pieces in new original stock, ensuring availability for procurement and production requirements.

Q: Can I use the CreeLED XP-E in existing PCB designs without modification?

A: Yes. The identical 1414 (3535 metric) package footprint, compatible electrical parameters, and negligible physical dimension variance allow direct substitution in existing PCB designs without layout or assembly modifications.
