LED LH351B SPHWH2L3D30CD4TMK3 Equivalent & Substitute Parts

Part Overview

The SPHWH2L3D30CD4TMK3 is a surface-mount LED from Samsung Semiconductor's LH351B series, featuring neutral white 4000K color temperature with 3-step MacAdam Ellipse binning. This component delivers 145 lm at 85°C under 350mA test current with a 120° viewing angle in a compact 3535 metric package (1414 case).

The LH351B series carries a "Not For New Designs" product status, indicating Samsung has discontinued active development and support for this line. This status necessitates identification of functionally equivalent alternatives for ongoing production requirements, maintenance applications, and design transitions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPHWH2L3D30CD4TMK3 is determined by strict alignment across the following parameters:

Package Compatibility: The substitute must use the 1414 (3535 Metric) package to ensure PCB footprint compatibility without redesign.

Electrical Performance: Forward voltage must remain within acceptable circuit design tolerances (2.72V to 2.8V range). Test current must be 350mA to maintain performance baseline. Luminous flux must fall within or exceed the 130-160 lm specification range at 85°C.

Color Specification: Color temperature must be 4000K neutral white. CRI must be 70 or higher to maintain color rendering performance.

Optical Characteristics: Viewing angle must be 115° or greater to ensure equivalent or superior light distribution.

Regulatory Compliance: RoHS compliance is mandatory. Thermal resistance of 4°C/W is the established standard for this package class.

Mounting and Assembly: Surface-mount technology is required. Maximum current rating must be 1.5A or higher.

The XPGBWT-01-0000-00KE5 from CreeLED meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: The XPGBWT-01-0000-00KE5 (CreeLED XLamp® XP-G2) is the qualified equivalent substitute for the SPHWH2L3D30CD4TMK3.

Justification Based on Product Status: The Samsung LH351B series carries "Not For New Designs" status, indicating end-of-life trajectory. The CreeLED XLamp® XP-G2 series maintains "Active" product status, ensuring ongoing manufacturer support, availability, and process stability for production applications.

Compliance Alignment: Both components are RoHS Compliant and carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, ensuring regulatory equivalence across markets.

Performance Characteristics: The substitute delivers superior luminous efficiency (168 lm/W versus 148 lm/W) while maintaining equivalent color temperature, CRI, and electrical ratings. Flux output at 85°C (160 lm) exceeds the original specification minimum (130 lm) and falls within the original tolerance band (130-160 lm).

Electrical Compatibility: Forward voltage difference of 0.08V (2.72V versus 2.8V) is within standard circuit design tolerances and does not require power supply modification for typical LED driver applications.

Mechanical Fit: Package dimensions are compatible within standard PCB assembly tolerances. The 0.33mm height difference (2.39mm versus 2.06mm) is acceptable for surface-mount reflow processes and does not impact clearance in standard applications.

Optical Performance: Viewing angle reduction from 120° to 115° represents a 4.2% change in beam width, acceptable for most lighting applications where the original 120° specification was not a critical design constraint.

Frequently Asked Questions (FAQ)

Q: Can the XPGBWT-01-0000-00KE5 be used as a direct drop-in replacement without circuit modification?

A: Yes. The forward voltage difference of 0.08V is within standard LED driver tolerance windows. No circuit redesign is required for typical constant-current driver applications. Verify your specific driver's input voltage range if operating near minimum supply voltage limits.

Q: What is the impact of the 5° viewing angle difference (120° to 115°)?

A: The viewing angle reduction represents a 4.2% narrowing of the light distribution cone. For applications where uniform wide-angle illumination is critical, measure the actual light distribution in your optical system. For most general lighting applications, this difference is not perceptible.

Q: Why does the substitute have higher luminous flux (160 lm vs 145 lm) at the same test current?

A: The CreeLED XLamp® XP-G2 represents a newer LED technology generation with improved phosphor efficiency and die design. Higher flux output at equivalent current is a performance advantage and does not create compatibility issues.

Q: Are there packaging format differences I should consider?

A: The original part is supplied in Tape & Reel (TR) format; the substitute is available in Cut Tape (CT) format. Both are standard packaging formats. Verify your assembly equipment compatibility with the available packaging format. Reel availability may differ by distributor.

Q: What is the significance of the "Not For New Designs" status on the Samsung part?

A: This status indicates Samsung has concluded active development and support for the LH351B series. Future availability cannot be guaranteed, and technical support may become limited. The substitute's "Active" status ensures long-term availability and manufacturer support.

Q: Is the 0.33mm height difference (2.06mm vs 2.39mm) a concern for PCB clearance?

A: For standard surface-mount applications with typical component spacing, this difference is not problematic. Verify clearance in your specific PCB layout if components are mounted in close proximity to other tall components or if height-constrained applications are involved.

Q: Do both parts have identical thermal management characteristics?

A: Yes. Both components have 4°C/W thermal resistance. Thermal management design based on the original part specifications remains valid for the substitute.

Q: What is the difference between 3-Step MacAdam Ellipse binning and standard 4000K specification?

A: The Samsung part specifies 3-Step MacAdam Ellipse binning, a tighter color tolerance specification. The CreeLED substitute specifies standard 4000K without explicit MacAdam binning notation. Both deliver 4000K neutral white color. If your application requires certified MacAdam binning, confirm CreeLED's available binning options with your distributor.
