Substitute Part Grouping Explanation

Substitution of the SPHWHTL3D50EE4V0MF is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Series: LH351C (all substitutes must belong to this series)
• Package / Case: 1414 (3535 Metric) (mechanical compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)
• Forward Voltage (Vf): 2.9V (electrical compatibility)
• Maximum Current: 2A (current handling capability)
• Viewing Angle: 128° (optical characteristics)
• Size / Dimension: 3.50mm × 3.50mm (PCB footprint compatibility)
• Height - Seated (Max): 2.46mm (clearance compatibility)
• Thermal Resistance: 3°C/W (thermal management)

Secondary Substitution Parameters:

• Color: White, Warm (color family)
• CRI: 80 (color rendering consistency)
• Test Current: 700mA (nominal operating point)

Substitutes are grouped into two categories:

1. Direct Equivalent (Packaging Variant): SPHWHTL3D50EE4V0NF — Identical electrical specifications and CCT (3000K) with active product status and alternative packaging (Tape & Reel).

2. Parametric Equivalent (CCT Variant): SPHWHTL3D50EE4W0MF and SPHWHTL3D50EE4WPMF — Identical electrical and mechanical specifications with alternative CCT (2700K instead of 3000K), both with active product status and Tape & Reel packaging.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Identical CCT 3000K):

SPHWHTL3D50EE4V0NF is the recommended direct substitute for SPHWHTL3D50EE4V0MF. Both parts maintain identical electrical specifications (2.9V forward voltage, 700mA test current, 2A maximum current), identical optical characteristics (3000K CCT, 128° viewing angle, CRI 80), and identical mechanical compatibility (3535 metric package, 2.46mm seated height). The primary difference is product status: SPHWHTL3D50EE4V0NF carries active product status, ensuring long-term supply availability. The substitute also features improved luminous flux (300lm vs. 280lm at 85°C) and higher luminous efficacy (148 lm/W vs. 138 lm/W), representing a performance enhancement. Packaging format differs (Tape & Reel vs. Bulk), which is compatible with standard automated assembly processes.

For Parametric Substitution (Alternative CCT 2700K):

SPHWHTL3D50EE4W0MF and SPHWHTL3D50EE4WPMF are parametric equivalents suitable when application requirements permit a shift from 3000K to 2700K color temperature. Both maintain all electrical and mechanical specifications identical to the main part. Both carry active product status. SPHWHTL3D50EE4WPMF offers higher inventory availability (1091 Pcs vs. 765 Pcs). Selection between these two parametric equivalents is determined by supply chain and inventory requirements; electrical and optical performance are identical.

Compliance and Certification:

All parts (main and substitutes) share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, confirming regulatory equivalence for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q1: Can SPHWHTL3D50EE4V0NF be used as a direct replacement for SPHWHTL3D50EE4V0MF without circuit modification?

A: Yes. SPHWHTL3D50EE4V0NF is a direct electrical and mechanical equivalent. Forward voltage (2.9V), maximum current (2A), and all optical parameters (3000K CCT, 128° viewing angle, CRI 80) are identical. The 3535 metric package footprint and 2.46mm seated height ensure PCB compatibility without layout changes. The substitute actually provides improved luminous flux (300lm vs. 280lm) and efficacy (148 lm/W vs. 138 lm/W), representing a performance upgrade.

Q2: What is the difference between the main part and SPHWHTL3D50EE4V0NF?

A: The primary differences are product status and packaging format. SPHWHTL3D50EE4V0NF is active (vs. obsolete), supplied in Tape & Reel format (vs. bulk), and demonstrates higher luminous output and efficacy. All electrical and mechanical specifications remain identical.

Q3: Can SPHWHTL3D50EE4W0MF or SPHWHTL3D50EE4WPMF replace the main part?

A: These parts are parametric equivalents suitable only if application requirements permit a color temperature shift from 3000K to 2700K. All electrical specifications (2.9V, 700mA, 2A) and mechanical parameters (3535 package, 2.46mm height) remain identical. The warmer 2700K color temperature may alter perceived lighting characteristics in the application.

Q4: What is the significance of the Tape & Reel packaging format for the substitute parts?

A: Tape & Reel (TR) packaging is the standard format for automated surface-mount assembly processes. It enables high-speed pick-and-place machine compatibility and is preferred for production environments. Bulk packaging (main part) is typically used for manual assembly or lower-volume applications. Both formats are mechanically and electrically compatible; the difference is assembly process optimization.

Q5: How do the luminous flux specifications differ between the main part and SPHWHTL3D50EE4V0NF?

A: The main part specifies 280lm (250–310lm range) at 85°C, while SPHWHTL3D50EE4V0NF specifies 300lm (270–330lm range) at 85°C. This represents a 7% increase in nominal flux and a wider tolerance band, indicating improved manufacturing consistency in the active product variant.

Q6: Are there any thermal management differences between the parts?

A: No. All parts share identical thermal resistance of 3°C/W, ensuring equivalent thermal performance in PCB thermal management calculations and thermal modeling.

Q7: What does MSL (Moisture Sensitivity Level) indicate, and how does it affect part selection?

A: MSL indicates moisture sensitivity during storage and handling. The main part is MSL 1 (unlimited shelf life), while SPHWHTL3D50EE4V0NF is MSL 2A (4-week shelf life after opening). MSL 2A requires controlled storage conditions and baking procedures before reflow soldering if shelf life is exceeded. For applications with standard inventory management practices, this difference is operationally manageable.

Q8: Can I mix the main part and substitute parts in the same production batch?

A: Mixing SPHWHTL3D50EE4V0MF and SPHWHTL3D50EE4V0NF is not recommended for the same production batch due to different product status designations and potential supply discontinuation of the obsolete variant. For new production, exclusive use of SPHWHTL3D50EE4V0NF is recommended. Mixing 3000K and 2700K variants (parametric equivalents) in the same batch will result in visible color temperature variation and is not recommended for applications requiring color uniformity.

Q9: What certifications and compliance standards apply to all substitute parts?

A: All parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. These designations confirm regulatory equivalence for export control and tariff classification purposes. No additional compliance documentation is required for substitution.

Q10: Which substitute part should I select for new design implementations?

A: For new designs requiring 3000K color temperature, select SPHWHTL3D50EE4V0NF. It offers active product status, improved luminous performance, and standard Tape & Reel packaging for automated assembly. For applications where 2700K is acceptable, SPHWHTL3D50EE4WPMF offers the highest inventory availability (1091 Pcs) and identical electrical/mechanical specifications.
