Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHT325AD5YBUMS0 is determined by alignment across the following critical parameters:

Color and CCT Match: Both the main part and substitute must deliver warm white light at 3500K to maintain color consistency in end-application lighting systems.

Luminous Flux Compatibility: The substitute must deliver comparable luminous output at its specified test current. The SPMWHT325AD5YBUMS0 produces 67 lm at 100 mA; substitutes operating at different test currents must provide equivalent or superior flux density to ensure functional parity.

Electrical Characteristics: Forward voltage and maximum current ratings must be compatible with existing circuit designs. Variations in Vf and Imax affect power supply requirements and thermal management.

CRI Specification: A CRI of 80 is maintained across substitutes to preserve color rendering quality in warm white applications.

Surface Mount Compatibility: All substitutes must be surface mount devices suitable for automated assembly processes.

Regulatory Compliance: RoHS compliance and ECCN classification (EAR99) are maintained across all substitutes.

The L130-3580003000W21 (Lumileds LUXEON 3030 2D) qualifies as a substitute based on matching CCT, CRI, color specification, surface mount configuration, and regulatory compliance, despite differences in package footprint and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SPMWHT325AD5YBUMS0 is obsolete, necessitating transition to active alternatives. The L130-3580003000W21 maintains active product status with Lumileds, ensuring long-term availability and supply chain stability.

Compliance Alignment: Both components meet EAR99 export classification and RoHS requirements. The substitute achieves ROHS3 compliance, representing current regulatory standards.

Electrical Performance: The L130-3580003000W21 operates at 6.1V (versus 5.96V) with a test current of 120 mA (versus 100 mA). Circuit designs must accommodate the 0.14V increase in forward voltage and the 20 mA increase in test current. The substitute delivers superior luminous efficacy (127 lm/W versus 112 lm/W), resulting in higher flux output (93 lm versus 67 lm) at the higher test current.

Thermal Performance: The L130-3580003000W21 exhibits lower thermal resistance (12°C/W versus 15°C/W), improving heat dissipation characteristics.

Package Footprint Differences: The substitute uses a 3030 metric package (3.00 × 3.00 mm) compared to the original 3623 package (3.60 × 2.30 mm). PCB layout modifications are required. The substitute is slightly lower in profile (0.62 mm versus 0.70 mm), which may benefit space-constrained designs.

Moisture Sensitivity: The substitute carries MSL 3 (168 hours) versus MSL 2A (4 weeks), requiring adjusted handling and storage protocols during manufacturing.

Frequently Asked Questions (FAQ)

Q: Can the L130-3580003000W21 directly replace the SPMWHT325AD5YBUMS0 without circuit modification?

A: No. While both components deliver 3500K warm white light with CRI 80, the substitute requires circuit adjustments. The forward voltage difference (6.1V versus 5.96V) and higher test current (120 mA versus 100 mA) necessitate power supply and current-limiting resistor recalculation. PCB layout changes are mandatory due to different package footprints.

Q: What are the key compatibility criteria for warm white LED substitution?

A: Substitution requires matching CCT (3500K), CRI (80), color specification (warm white), surface mount configuration, and regulatory compliance (RoHS, ECCN). Electrical parameters (Vf, test current, maximum current) and thermal characteristics must be evaluated within the context of the specific application circuit.

Q: How does the package footprint difference affect PCB design?

A: The original SPMWHT325AD5YBUMS0 uses a 3623 package (3.60 × 2.30 mm), while the L130-3580003000W21 uses a 3030 metric package (3.00 × 3.00 mm). Pad layouts, trace routing, and thermal vias must be redesigned. The substitute's smaller footprint may reduce PCB area requirements, but existing pad patterns are incompatible.

Q: What is the impact of the forward voltage increase from 5.96V to 6.1V?

A: The 0.14V increase affects power supply design and current-limiting circuit calculations. In series-connected LED strings, this voltage rise accumulates across multiple components. Power dissipation increases proportionally. Existing power supply designs must be re-evaluated for voltage headroom and thermal management.

Q: Why does the substitute deliver higher luminous flux (93 lm versus 67 lm)?

A: The L130-3580003000W21 is tested at a higher current (120 mA versus 100 mA) and exhibits superior luminous efficacy (127 lm/W versus 112 lm/W). Higher test current and improved efficiency combine to produce greater absolute flux output. Application designs must account for this increased light output.

Q: How do the moisture sensitivity levels differ, and what does this mean for manufacturing?

A: The original component carries MSL 2A (4-week floor life), while the substitute carries MSL 3 (168-hour floor life). MSL 3 components require more frequent baking cycles and shorter exposure times during assembly. Manufacturing processes must be adjusted to comply with the stricter moisture sensitivity specification.

Q: Are there viewing angle differences between these components?

A: The original SPMWHT325AD5YBUMS0 specifies a 120° viewing angle. The L130-3580003000W21 does not provide a viewing angle specification in the available data. Application designs dependent on specific beam angle characteristics require additional verification with the manufacturer.
