Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHT325AD5YBT0SC is determined by alignment across the following critical parameters:

Color and Correlated Color Temperature (CCT): Both the main part and substitute must operate at white neutral 4000K to maintain consistent color output in lighting applications.

Electrical Characteristics: Forward voltage (Vf), test current, and maximum current ratings must be compatible with existing circuit designs. The substitute part operates at 6.1V with a 120mA test current, representing a minor increase in both parameters within acceptable design tolerances.

Luminous Output: Flux measurements at 25°C and lumens per watt efficiency determine brightness performance. The substitute delivers 92 lumens at 120mA test current, compared to 85 lumens at 100mA for the main part.

Optical Properties: Viewing angle and Color Rendering Index (CRI) affect light distribution and color accuracy. The substitute provides a 116° viewing angle with CRI of 90, compared to 120° and CRI of 80 for the main part.

Mechanical Compatibility: Package type, physical dimensions, and mounting method must accommodate existing PCB layouts. The substitute uses a 1212 (3030 Metric) package measuring 3.00mm x 3.00mm, compared to the 3623 package at 3.60mm x 2.30mm for the main part.

Compliance and Reliability: RoHS status, moisture sensitivity level, and thermal characteristics ensure regulatory compliance and long-term reliability in production environments.

Parameter Comparison

Engineering Selection Recommendations

The L130-4090003000W21 (Lumileds LUXEON 3030 2D) serves as a functional equivalent to the obsolete SPMWHT325AD5YBT0SC. Both components share identical color temperature (4000K neutral white) and mounting methodology (surface mount), establishing baseline compatibility.

The substitute part carries Active product status, ensuring ongoing availability and supply chain continuity. It meets ROHS3 compliance, exceeding the RoHS Compliant standard of the main part. Both components carry EAR99 ECCN classification and identical HTSUS codes (8541.41.0000), confirming regulatory alignment.

Electrical parameter differences are minor: the substitute operates at 6.1V forward voltage versus 5.96V, with a 120mA test current compared to 100mA. These variations fall within typical design tolerance ranges for LED applications. The substitute delivers 92 lumens at test current, exceeding the main part's 85 lumens, while operating at 126 lm/W versus 143 lm/W.

The substitute provides superior color rendering (CRI 90 versus 80), beneficial for applications requiring enhanced color accuracy. Thermal resistance improves to 12°C/W from 15°C/W, supporting better heat dissipation in compact designs.

Package geometry differs: the substitute uses a 3030 metric package (3.00mm x 3.00mm) versus the 3623 package (3.60mm x 2.30mm). PCB layout modifications are required to accommodate this dimensional change. The substitute's lower profile (0.62mm versus 0.70mm) provides design flexibility for space-constrained applications.

Moisture sensitivity increases from MSL 2A to MSL 3, requiring adjusted handling protocols during manufacturing and storage.

Frequently Asked Questions (FAQ)

Q: Can the L130-4090003000W21 directly replace the SPMWHT325AD5YBT0SC without circuit modifications?

A: Direct replacement requires circuit evaluation. The substitute operates at 6.1V forward voltage compared to 5.96V, and draws 120mA at test current versus 100mA. Power supply and current-limiting resistor values must be recalculated to accommodate these electrical differences. PCB layout modifications are mandatory due to package geometry changes (3030 metric versus 3623).

Q: What are the key compatibility factors for this substitution?

A: Color temperature (4000K neutral white), mounting type (surface mount), and compliance standards (RoHS/ROHS3) establish primary compatibility. Electrical parameters (forward voltage and test current) and optical characteristics (viewing angle and CRI) require circuit and optical design review. Physical package dimensions necessitate PCB redesign.

Q: How do the luminous output specifications compare?

A: The substitute delivers 92 lumens at 120mA test current, compared to 85 lumens at 100mA for the main part. When normalized to equivalent test conditions, the substitute provides approximately 8% higher luminous output. Lumens per watt efficiency decreases from 143 lm/W to 126 lm/W due to higher operating current.

Q: Are there thermal management differences between these parts?

A: The substitute exhibits superior thermal performance with 12°C/W thermal resistance versus 15°C/W for the main part. This 20% improvement in thermal conductivity supports higher current operation and better heat dissipation in compact lighting assemblies.

Q: What packaging and handling considerations apply to the substitute?

A: The L130-4090003000W21 ships in Tape & Reel (TR) format with MSL 3 moisture sensitivity (168 hours), compared to MSL 2A (4 weeks) for the main part. Stricter moisture control during storage and assembly is required. The 3030 metric package footprint differs from the 3623 package, requiring PCB layout modifications and updated assembly documentation.

Q: Does the substitute provide improved color rendering?

A: Yes. The substitute achieves CRI 90 compared to CRI 80 for the main part, providing superior color accuracy and rendering quality. This enhancement benefits applications requiring high-fidelity color reproduction in neutral white lighting.

Q: What is the product availability status for each part?

A: The SPMWHT325AD5YBT0SC is classified as Obsolete with 830 units in current inventory. The L130-4090003000W21 carries Active product status with 6031 units available, ensuring long-term supply chain reliability and design continuity.
