Substitute Part Grouping Explanation

Substitute parts for the SPHWHTL3DA0GF4U0P6 are identified based on strict electrical and mechanical parameter alignment within the LH351D series. The substitution logic is based on the following critical parameters:

Electrical Compatibility:

• Forward voltage (Vf): 3V nominal
• Test current: 1.05A
• Maximum current rating: 3A
• Luminous flux @ 85°C: 350lm (320–380lm range)
• Lumens per watt efficiency: 111 lm/W
• CRI: 90

Mechanical Compatibility:

• Package format: 1414 (3535 Metric)
• Mounting type: Surface Mount
• Physical dimensions: 3.50mm × 3.50mm
• Maximum seated height: 2.46mm
• Thermal resistance: 2.2°C/W

Compliance & Status:

• Product status: Active
• RoHS Compliant
• MSL rating: 2A (4 Weeks)

Substitute parts maintain identical electrical performance, thermal characteristics, and mechanical footprint. Variations in correlated color temperature (CCT) within the warm white spectrum (3000K–3500K) are permitted substitutions when application requirements allow flexibility in color temperature selection.

Parameter Comparison

Engineering Selection Recommendations

SPHWHTL3DA0GF4UPP6 is a direct parametric equivalent to SPHWHTL3DA0GF4U0P6. Both parts share identical electrical specifications, thermal characteristics, mechanical dimensions, and compliance certifications. Selection between these two parts is based on inventory availability and supply chain considerations. Both are Active status products with RoHS Compliance and MSL 2A rating.

SPHWHTL3DA0GF4VPP6 is a substitute part with equivalent electrical performance and mechanical compatibility. The primary difference is the correlated color temperature: 3000K versus 3500K. This part is suitable for applications where a warmer color temperature (3000K) is acceptable or preferred. All other parameters—forward voltage, test current, luminous flux, efficiency, CRI, viewing angle, package format, thermal resistance, and compliance certifications—are identical to the main part. This part is also Active status with RoHS Compliance and MSL 2A rating.

Selection criteria:

• Use SPHWHTL3DA0GF4U0P6 or SPHWHTL3DA0GF4UPP6 when 3500K color temperature is specified.
• Use SPHWHTL3DA0GF4VPP6 when 3000K color temperature is specified or when application requirements permit warmer light output.
• All three parts are suitable for surface mount assembly on standard PCB equipment.
• All three parts meet RoHS compliance requirements for regulated markets.

Frequently Asked Questions (FAQ)

Q: Can SPHWHTL3DA0GF4UPP6 be used as a direct replacement for SPHWHTL3DA0GF4U0P6?

A: Yes. SPHWHTL3DA0GF4UPP6 is a parametric equivalent with identical electrical specifications, forward voltage (3V), test current (1.05A), luminous flux (350lm @ 85°C), efficiency (111 lm/W), CRI (90), viewing angle (128°), package format (3535 metric), thermal resistance (2.2°C/W), and compliance certifications. Direct PCB substitution is supported without circuit modification.

Q: What is the difference between SPHWHTL3DA0GF4U0P6 and SPHWHTL3DA0GF4VPP6?

A: The primary difference is correlated color temperature: SPHWHTL3DA0GF4U0P6 operates at 3500K, while SPHWHTL3DA0GF4VPP6 operates at 3000K. All other electrical, thermal, and mechanical parameters are identical. SPHWHTL3DA0GF4VPP6 produces warmer light output suitable for applications requiring lower color temperature.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the 1414 (3535 metric) package format with identical dimensions (3.50mm × 3.50mm) and maximum seated height (2.46mm). Surface mount assembly equipment and PCB layouts designed for one part accommodate all three parts without modification.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. SPHWHTL3DA0GF4UPP6 and SPHWHTL3DA0GF4VPP6 are both RoHS Compliant with MSL 2A (4 Weeks) rating, matching the main part SPHWHTL3DA0GF4U0P6. All three parts are Active status products suitable for regulated markets.

Q: Can SPHWHTL3DA0GF4VPP6 be used in applications designed for 3500K light output?

A: SPHWHTL3DA0GF4VPP6 operates at 3000K, which is warmer than the specified 3500K. Use this part only when application requirements explicitly permit 3000K color temperature or when warmer light output is acceptable. Electrical performance and efficiency are equivalent; the difference is color temperature only.

Q: What thermal characteristics should be considered when selecting between these parts?

A: All three parts have identical thermal resistance of 2.2°C/W. Thermal performance in the application is determined by PCB thermal design, ambient temperature, and drive current. At the specified test current of 1.05A, thermal characteristics are equivalent across all three parts.

Q: Are there any packaging or handling differences between these parts?

A: All three parts are supplied in Tape & Reel (TR) packaging with MSL 2A (4 Weeks) moisture sensitivity rating. Handling, storage, and reflow procedures are identical. No special precautions are required when substituting between these parts.
