LED LH351B SPHWH2L3D30CD4TMJ3 Equivalent & Substitute Parts

Part Overview

The SPHWH2L3D30CD4TMJ3 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 135 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 continuity where existing inventory becomes depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPHWH2L3D30CD4TMJ3 is determined by strict alignment across the following parameters:

Package Compatibility: The substitute must use the 1414 (3535 Metric) surface-mount package to ensure mechanical fit on existing PCB layouts without redesign.

Optical Specifications: Color temperature must be neutral white 4000K to maintain color consistency in applications. CRI of 70 or higher preserves color rendering quality. Viewing angle of 115° to 120° ensures comparable light distribution characteristics.

Electrical Parameters: Forward voltage must fall within the range 2.7V to 2.9V to maintain circuit compatibility with existing driver designs. Test current of 350mA establishes the performance baseline; substitutes must deliver equivalent or superior luminous flux at this current level.

Luminous Output: Flux output at 85°C must fall within or exceed the 120–150 lm specification range to meet brightness requirements.

Regulatory Compliance: RoHS compliance is mandatory. ECCN and HTSUS classifications must align for supply chain continuity.

Thermal Characteristics: Thermal resistance of 4°C/W or lower ensures thermal management compatibility with existing heat sink designs.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: The XPGBWT-01-R250-00HE5 (CreeLED XLamp® XP-G2) qualifies as a direct functional equivalent to the SPHWH2L3D30CD4TMJ3 based on strict parameter alignment.

Justification:

The substitute meets all critical substitution criteria: identical 3535 metric package, matching neutral white 4000K color temperature, compatible forward voltage (2.72V vs. 2.8V), identical test current (350mA), and luminous flux within specification (144 lm vs. 135 lm baseline). Both components share identical thermal resistance (4°C/W), maximum current rating (1.5A), CRI (70), and regulatory classifications (RoHS Compliant, EAR99, HTSUS 8541.41.0000).

Product Status Advantage: The XPGBWT-01-R250-00HE5 carries "Active" product status, ensuring ongoing manufacturer support, availability, and technical documentation. The original SPHWH2L3D30CD4TMJ3 is marked "Not For New Designs," indicating Samsung has concluded active development for the LH351B series.

Performance Characteristics: The substitute demonstrates superior luminous efficiency (152 lm/W vs. 138 lm/W), delivering higher light output per watt while maintaining identical electrical and thermal parameters. Viewing angle difference (115° vs. 120°) represents a 5° reduction, acceptable for most optical applications.

Mechanical Fit: Dimensional differences are negligible: the substitute is 0.05mm smaller in lateral dimension and 0.33mm taller in seated height. These variations remain within standard PCB assembly tolerances and do not require layout modifications.

Compliance Continuity: Both components maintain identical regulatory compliance status, ensuring supply chain and certification continuity.

Frequently Asked Questions (FAQ)

Q: Can the XPGBWT-01-R250-00HE5 be used as a direct drop-in replacement for the SPHWH2L3D30CD4TMJ3?

A: Yes. Both components use the identical 1414 (3535 Metric) surface-mount package with compatible mechanical dimensions. Forward voltage (2.72V vs. 2.8V) and test current (350mA) are compatible with existing circuit designs. No PCB layout modifications are required.

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

A: This designation indicates Samsung has concluded active development and support for the LH351B series. Existing inventory will eventually deplete, and long-term availability cannot be guaranteed. The substitute XPGBWT-01-R250-00HE5 carries "Active" status, ensuring continued manufacturer support and supply availability.

Q: How do the luminous flux specifications compare?

A: The original part specifies 135 lm at 85°C (120–150 lm range). The substitute delivers 144 lm at 85°C (139–148 lm range). The substitute output falls within the original specification range and exceeds the baseline by 9 lm, representing approximately 6.7% higher brightness at identical test current.

Q: Are there differences in color temperature or color rendering?

A: Both components are specified as neutral white 4000K with CRI 70. The original part includes "3-Step MacAdam Ellipse" binning notation, indicating tighter color tolerance. The substitute does not specify MacAdam binning but maintains identical CCT and CRI values. For applications requiring strict color consistency, verify MacAdam binning availability with the substitute manufacturer.

Q: What is the impact of the 5° viewing angle difference?

A: The original part specifies 120° viewing angle; the substitute specifies 115°. This 5° reduction represents approximately 4% narrower light distribution. For applications requiring wide-angle illumination, this difference may be perceptible. For most general lighting applications, this variation is negligible.

Q: Do thermal management considerations change with the substitute?

A: No. Both components specify identical thermal resistance of 4°C/W. Existing heat sink designs and thermal management strategies remain valid without modification.

Q: Are regulatory and compliance certifications identical?

A: Yes. Both components are RoHS Compliant, carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, and meet all specified regulatory requirements. Supply chain and certification continuity is maintained.

Q: What is the maximum current rating for both parts?

A: Both the original and substitute components are rated for maximum current of 1.5A. Circuit designs operating at or below 350mA test current remain fully compatible.

Q: Are there any height or dimensional constraints I should consider?

A: The substitute is 0.33mm taller in seated height (2.39mm vs. 2.06mm). For applications with tight vertical clearance constraints, verify that this additional height does not conflict with overlying components or enclosure geometry. Lateral dimensions are compatible within standard PCB assembly tolerances.
