Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHT325AD5YBV0SC is determined by the following critical parameters:

Primary Substitution Criteria:

• Color specification: White, Warm
• CCT (Correlated Color Temperature): 3000K
• CRI (Color Rendering Index): 80 minimum
• Mounting type: Surface Mount
• Electrical compatibility: Forward voltage range 5.96V–6.1V, test current 100–120mA
• Luminous flux: 80–90 lm at rated test current
• RoHS compliance status

Secondary Compatibility Factors:

• Package footprint and height constraints (3.60 mm × 2.30 mm, 0.70 mm max height for LM362A; 3.00 mm × 3.00 mm, 0.62 mm max height for LUXEON 3030 2D)
• Thermal resistance characteristics
• Moisture sensitivity level and storage requirements

The Lumileds L130-3080003000W21 (LUXEON 3030 2D series) qualifies as a substitute based on matching color temperature (3000K), CRI (80), warm white color specification, surface mount configuration, and electrical parameters within acceptable operating ranges. However, package dimensions differ, requiring PCB layout verification.

Engineering Selection Recommendations

Substitution Feasibility:

The L130-3080003000W21 (Lumileds LUXEON 3030 2D) is a functional substitute for the obsolete SPMWHT325AD5YBV0SC based on the following engineering factors:

1. Color Temperature Match: Both components operate at 3000K warm white, ensuring identical color appearance in end-use applications.

2. CRI Equivalence: Both maintain CRI of 80, providing equivalent color rendering performance.

3. Electrical Compatibility: Forward voltage differential (5.96V vs. 6.1V) is 0.14V, within typical LED circuit tolerance margins. Test current increase from 100mA to 120mA requires circuit current-limiting verification but remains within acceptable design parameters.

4. Luminous Output: The substitute delivers 90 lm at 120mA versus 80 lm at 100mA for the original part. Normalized to equivalent test conditions, output remains comparable.

5. Compliance Status: Both components meet RoHS requirements. The substitute carries ROHS3 Compliant status, representing current regulatory alignment.

6. Thermal Performance: The substitute exhibits superior thermal resistance (12°C/W vs. 15°C/W), indicating improved heat dissipation characteristics.

Design Considerations:

• PCB Layout Modification Required: Package footprint change from 3.60 mm × 2.30 mm to 3.00 mm × 3.00 mm necessitates PCB layout revision. The substitute is smaller in one dimension (2.30 mm to 3.00 mm width) and shorter in height (0.70 mm to 0.62 mm).

• Moisture Handling: MSL rating change from 2A (4 Weeks) to 3 (168 Hours) requires adjusted storage and handling protocols. The substitute allows extended dry storage periods.

• Current Supply Circuit: Existing current-limiting circuits must accommodate the 20mA increase in test current and 0.14V forward voltage increase.

Frequently Asked Questions (FAQ)

Q1: Can the L130-3080003000W21 directly replace the SPMWHT325AD5YBV0SC without circuit modification?

A: Direct replacement requires circuit verification. The forward voltage increase of 0.14V and test current increase of 20mA must be evaluated within the specific power supply and current-limiting circuit design. PCB layout modification is mandatory due to different package footprints.

Q2: What is the impact of the package size difference on PCB design?

A: The LUXEON 3030 2D (3.00 mm × 3.00 mm) differs from the LM362A (3.60 mm × 2.30 mm). The substitute is smaller in length but larger in width. Height reduction from 0.70 mm to 0.62 mm may improve clearance in constrained assemblies. Complete PCB footprint redesign is required.

Q3: Are the color characteristics identical between these two LEDs?

A: Yes. Both components specify 3000K CCT and CRI of 80, ensuring identical warm white color appearance and color rendering performance in end-use applications.

Q4: How does the luminous flux difference affect system performance?

A: The substitute delivers 90 lm at 120mA test current versus 80 lm at 100mA for the original. This represents approximately 12.5% higher output at a 20% higher test current. System brightness will increase proportionally if operated at equivalent current levels.

Q5: What are the storage and handling differences?

A: The substitute carries MSL 3 (168 Hours) versus MSL 2A (4 Weeks) for the original. This allows extended dry storage periods of up to 168 hours before moisture absorption becomes critical. Standard moisture-controlled storage practices remain applicable.

Q6: Is the substitute suitable for high-temperature applications?

A: The substitute exhibits superior thermal resistance (12°C/W vs. 15°C/W), indicating better heat dissipation. This characteristic supports improved performance in elevated ambient temperature environments.

Q7: What regulatory compliance differences exist?

A: Both components meet RoHS requirements. The substitute carries ROHS3 Compliant status, representing alignment with current EU regulatory standards. Both are EAR99 classified for export control purposes.
