Substitute Part Grouping Explanation

Substitution of the SPHWHTL3DA0GF4T0P6 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Color temperature: 4000K (neutral white)
• Forward voltage: 3V nominal
• Test current: 1.05A
• Maximum current rating: 3A
• Luminous flux: 350lm at 85°C (320–380lm acceptable range)
• Color Rendering Index: 90 minimum

Mechanical Parameters:

• Package type: 1414 (3535 Metric)
• Mounting: Surface Mount
• Physical dimensions: 3.50mm × 3.50mm
• Maximum seated height: 2.46mm

Compliance Parameters:

• RoHS compliance status
• Moisture Sensitivity Level: 2A

The substitute part SPHWHTL3DA0GF4TPP6 matches all electrical and mechanical parameters specified above. The primary difference lies in packaging configuration (Tape & Reel variant designation) and RoHS certification version, with no impact on functional performance or physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SPHWHTL3DA0GF4TPP6

The SPHWHTL3DA0GF4TPP6 is a direct parametric equivalent to the SPHWHTL3DA0GF4T0P6. All electrical performance characteristics, mechanical dimensions, and thermal properties are identical. Both components share the same base product number (SPHWHTL3) and are manufactured by Samsung Semiconductor.

Compliance Considerations:

Both parts carry "Not For New Designs" status, indicating Samsung has discontinued active development and support for the LH351D series. The substitute part carries ROHS3 certification, which supersedes the RoHS Compliant designation of the main part, providing enhanced environmental compliance documentation.

Availability Factor:

The substitute part (SPHWHTL3DA0GF4TPP6) maintains significantly higher inventory availability (6113 units versus 792 units), making it the preferred selection for ongoing production requirements or future procurement cycles.

Application Compatibility:

No design modifications are required when substituting SPHWHTL3DA0GF4TPP6 for SPHWHTL3DA0GF4T0P6. The components are electrically and mechanically interchangeable across all specified operating parameters, circuit configurations, and thermal management implementations.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between SPHWHTL3DA0GF4T0P6 and SPHWHTL3DA0GF4TPP6?

A: The parts are parametrically identical in all electrical and mechanical specifications. The difference lies in the packaging designation suffix (T0P6 versus TPP6) and RoHS certification version (RoHS Compliant versus ROHS3 Compliant). These differences do not affect functional performance or physical compatibility.

Q: Can SPHWHTL3DA0GF4TPP6 be used as a direct replacement in existing designs?

A: Yes. The substitute part maintains identical forward voltage (3V), test current (1.05A), luminous flux (350lm at 85°C), color temperature (4000K), viewing angle (128°), and package dimensions (3535 metric). No circuit modifications or PCB redesign is required.

Q: Are there any thermal management differences between these parts?

A: No. Both parts have identical thermal resistance of 2.2°C/W. Thermal design calculations, heat sink requirements, and thermal management strategies remain unchanged when substituting the parts.

Q: What does "Not For New Designs" status mean for these components?

A: This designation indicates that Samsung has discontinued active product development and support for the LH351D series. Both the main part and substitute are in end-of-life status. Organizations should evaluate long-term alternatives for future product generations.

Q: Is the higher inventory of SPHWHTL3DA0GF4TPP6 significant for procurement?

A: Yes. The substitute part has 6113 units in stock compared to 792 units for the main part. For production planning and supply chain continuity, the substitute offers better availability for current and near-term requirements.

Q: Do both parts require the same handling and storage conditions?

A: Yes. Both parts carry identical Moisture Sensitivity Level (MSL) rating of 2A (4 Weeks), requiring the same storage, handling, and reflow procedures. No changes to manufacturing processes are necessary.

Q: What is the significance of ROHS3 certification on the substitute part?

A: ROHS3 represents an updated version of RoHS compliance documentation. It provides enhanced environmental compliance verification and is generally preferred for regulatory documentation purposes. The functional performance remains identical to the RoHS Compliant designation.
