LED LH351B SPHWH2L3D30ED4WMF3 Equivalent & Substitute Parts

Part Overview

The SPHWH2L3D30ED4WMF3 is a Samsung Semiconductor LH351B series warm white LED designed for general lighting applications. This component operates at 2700K color temperature with a 3-step MacAdam Ellipse specification, delivering 105 lm at 85°C under 350mA test current. The part is classified as "Not For New Designs," indicating that Samsung has discontinued active development for this product line. Engineers and procurement teams requiring warm white 3535 metric package LEDs with equivalent performance characteristics must identify suitable alternatives that maintain compatibility with existing circuit designs and thermal management requirements.

Substitute Part Grouping Explanation

Substitution of the SPHWH2L3D30ED4WMF3 is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Package type: 1414 (3535 Metric) surface mount form factor
• Color specification: Warm white
• CCT range: 2700K nominal
• CRI: 80 or higher
• Forward voltage: 2.7–2.9V typical range
• Test current: 350mA nominal operation
• Maximum current rating: 1.5A or greater
• Thermal resistance: 4°C/W or lower
• Viewing angle: 110° or greater
• Flux output: 90–120 lm range at 85°C, 350mA

Substitution Logic: The XPGBWT-H1-0000-00EZ8 (CreeLED XLamp® XP-G2) qualifies as a direct substitute because it meets all primary criteria. Both components operate at identical test current (350mA), share the same package footprint (3535 metric), deliver equivalent luminous flux within the specified range, maintain identical thermal resistance, and comply with RoHS requirements. The substitute exhibits superior efficiency (124 lm/W versus 107 lm/W) and maintains active product status, making it suitable for new designs where the original part is no longer available.

Parameter Comparison

Engineering Selection Recommendations

For Existing Designs (Maintenance & Repair): The XPGBWT-H1-0000-00EZ8 is a direct electrical and mechanical substitute for the SPHWH2L3D30ED4WMF3 in existing applications. Both components share identical package footprints, thermal characteristics, and electrical operating parameters at 350mA test current. The 0.08V forward voltage difference (2.8V versus 2.72V) is within typical circuit tolerance margins and does not require driver circuit modification. The substitute's superior luminous efficiency (124 lm/W versus 107 lm/W) results in lower power dissipation and improved thermal performance in existing designs.

For New Designs: The XPGBWT-H1-0000-00EZ8 is the recommended selection. The original SPHWH2L3D30ED4WMF3 carries "Not For New Designs" status, indicating Samsung has discontinued active support. The CreeLED XP-G2 substitute maintains active product status, ensuring long-term supply chain availability and continued manufacturer support. Both components comply with RoHS requirements and share identical thermal resistance specifications (4°C/W), eliminating the need for thermal management redesign.

Compliance Considerations: Both the original part and substitute are RoHS Compliant and carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. The substitute carries REACH Unaffected status, providing additional regulatory clarity for international applications. Moisture sensitivity levels differ (original: 2A at 4 weeks; substitute data not specified), requiring verification of storage and handling protocols for the substitute component.

Frequently Asked Questions (FAQ)

Q: Can the XPGBWT-H1-0000-00EZ8 be used as a direct drop-in replacement for the SPHWH2L3D30ED4WMF3?

A: Yes. Both components use identical 3535 metric package footprints, share the same 350mA test current, and operate within compatible forward voltage ranges (2.8V versus 2.72V). PCB layout and reflow profiles require no modification. The 0.33mm height difference (2.06mm versus 2.39mm) remains within standard surface mount assembly tolerances.

Q: What is the impact of the forward voltage difference on circuit design?

A: The 0.08V difference (2.8V original versus 2.72V substitute) is negligible in most LED driver circuits. Standard constant-current drivers maintain output current within ±5% tolerance across this voltage range. Verify driver specifications if operating near minimum or maximum voltage limits.

Q: Are there differences in color consistency between the two parts?

A: Both components specify 2700K warm white color temperature with CRI 80. The original part includes 3-step MacAdam Ellipse specification; the substitute specifies 2700K without MacAdam detail. For applications requiring strict color consistency, request MacAdam specification data from the substitute manufacturer.

Q: How does the higher efficiency of the substitute affect thermal management?

A: The substitute's superior efficiency (124 lm/W versus 107 lm/W) reduces power dissipation at identical current levels. Both components share 4°C/W thermal resistance, but the substitute generates less heat, improving overall thermal performance. Existing thermal designs remain valid without modification.

Q: What is the viewing angle difference impact?

A: The original part specifies 120° viewing angle; the substitute specifies 115°. This 5° difference is negligible in most lighting applications. Verify viewing angle requirements for specialized optical designs (e.g., narrow-beam spotlights or wide-angle flood applications).

Q: Are there supply chain advantages to using the substitute?

A: Yes. The substitute carries "Active" product status with 2629 units in stock, compared to the original's "Not For New Designs" status. The substitute ensures long-term availability and manufacturer support for future production runs.

Q: Do storage and handling requirements differ between the two parts?

A: The original part specifies MSL 2A (4 weeks). The substitute's moisture sensitivity level is not provided in available data. Confirm MSL specifications with the substitute manufacturer before establishing storage protocols, particularly for high-humidity environments or extended storage periods.
