Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPHWHTL3DA0GF4VPN6 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Series: LH351D
• Voltage - Forward (Vf) Typical: 3V
• Current - Test: 1.05A
• Current - Maximum: 3A
• Flux @ 85°C, Current - Test: 330lm (300–360lm range)
• Lumens/Watt @ Current - Test: 105 lm/W
• CRI (Color Rendering Index): 90
• Viewing Angle: 128°
• Package / Case: 1414 (3535 Metric)
• Size / Dimension: 3.50mm × 3.50mm
• Height - Seated (Max): 2.46mm
• Thermal Resistance of Package: 2.2°C/W
• Mounting Type: Surface Mount
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level (MSL): 2A (4 Weeks)

Variable Parameter (Allows Substitution):

• CCT (Correlated Color Temperature): 3000K (main part) vs. 2700K (substitute parts)

The identified substitute parts maintain identical electrical, thermal, and mechanical specifications while differing only in color temperature. Both substitute parts are from the active product status category, providing design continuity for applications transitioning from the end-of-life SPHWHTL3DA0GF4VPN6.

Parameter Comparison

Engineering Selection Recommendations

For End-of-Life Transition: The SPHWHTL3DA0GF4VPN6 carries "Not For New Designs" status, indicating Samsung has discontinued this specific part number. Both substitute parts—SPHWHTL3DA0GF4W0N6 and SPHWHTL3DA0GF4WPN6—are classified as "Active" products and maintain full compatibility with the original part across all electrical, thermal, and mechanical parameters.

Color Temperature Consideration: The primary difference between the main part and substitutes is the correlated color temperature: 3000K (main) versus 2700K (substitutes). Both remain within the warm white spectrum. Applications requiring the exact 3000K specification should evaluate whether 2700K operation is acceptable within system design constraints.

Inventory and Availability: SPHWHTL3DA0GF4WPN6 offers the highest inventory availability at 19,775 pieces, providing supply chain stability for volume production. SPHWHTL3DA0GF4W0N6 maintains lower inventory at 873 pieces.

Compliance and Certification: All parts maintain identical RoHS compliance status and Moisture Sensitivity Level (MSL) ratings, ensuring regulatory and handling requirements remain unchanged during substitution.

Frequently Asked Questions (FAQ)

Q: Can SPHWHTL3DA0GF4W0N6 and SPHWHTL3DA0GF4WPN6 be used interchangeably with SPHWHTL3DA0GF4VPN6?

A: Both substitute parts are electrically and mechanically interchangeable with the original part. The only difference is color temperature: 2700K versus 3000K. Substitution is valid if the application tolerates this color temperature shift within the warm white range.

Q: What is the significance of the "Not For New Designs" status on SPHWHTL3DA0GF4VPN6?

A: This designation indicates Samsung has ended active production and support for this specific part number. New designs should transition to active product variants such as SPHWHTL3DA0GF4WPN6 or SPHWHTL3DA0GF4W0N6 to ensure long-term supply availability and manufacturer support.

Q: Are the package dimensions identical across all three parts?

A: Yes. All three parts use the 1414 (3535 Metric) package with identical dimensions of 3.50mm × 3.50mm and maximum seated height of 2.46mm. PCB layout and thermal design remain unchanged during substitution.

Q: Do the substitute parts have the same thermal characteristics?

A: Yes. Thermal resistance of package is 2.2°C/W for all three parts, and flux output at 85°C test current is identical at 330lm (300–360lm range). Thermal management design does not require modification.

Q: What is the difference between SPHWHTL3DA0GF4W0N6 and SPHWHTL3DA0GF4WPN6?

A: Both parts are 2700K warm white LEDs with identical electrical and mechanical specifications. The primary difference is inventory availability: SPHWHTL3DA0GF4WPN6 has significantly higher stock (19,775 pcs vs. 873 pcs). Part number suffix variations reflect internal Samsung manufacturing or packaging designations but do not affect functional performance.

Q: Are RoHS compliance and moisture sensitivity requirements the same for all parts?

A: Yes. All three parts are RoHS Compliant and carry MSL rating 2A (4 Weeks), indicating identical handling and storage requirements. No changes to component procurement or assembly procedures are necessary during substitution.

Q: Can these parts be used in applications requiring exactly 3000K color temperature?

A: The substitute parts operate at 2700K, which is warmer than the original 3000K specification. Applications with strict color temperature requirements should evaluate whether 2700K output meets system performance criteria. The 300K difference represents a shift toward warmer (more amber) light output.
