Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWH3228FD5WAV0S2 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Color and CCT: White, Warm 3000K (exact match required)
• Package / Case: 1113 (2835 Metric) form factor (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Viewing Angle: 120° (exact match required)
• CRI: 80 (exact match required)
• Test Current: 150 mA (exact match required)
• Maximum Current: 160 mA (exact match required)
• Flux @ 25°C: 56 lm within 54–58 lm range (exact match required)
• Thermal Resistance: 25°C/W (exact match required)
• RoHS Status: RoHS Compliant (exact match required)
• MSL: 2A (4 Weeks) (exact match required)

Allowable Variation Parameters:

• Forward Voltage (Typ): 3.0V to 3.1V (minor variation acceptable within design margin)
• Lumens/Watt: 120–124 lm/W (efficiency variation acceptable with same lumen output)
• Product Status: Active substitutes are preferred over Not For New Designs status

The three substitute parts listed below meet all critical matching parameters and represent active product alternatives within the LM281BZ+ series evolution.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—SPMWH3228FD5WAV0SC, SPMWH3228FD5WAVKSC, and SPMWH3228FD5WAVMSC—are direct parametric equivalents of the SPMWH3228FD5WAV0S2 and are suitable for substitution in applications requiring warm white 3000K LEDs in the 2835 metric package.

Product Status Consideration: The substitute parts are classified as Active products, whereas the original SPMWH3228FD5WAV0S2 is Not For New Designs. This transition indicates Samsung's continued support for the LM281BZ+ series. For ongoing production and maintenance applications, the Active substitute parts provide superior long-term availability and supply chain stability.

Electrical Compatibility: The forward voltage difference between the main part (3.1V) and substitutes (3.0V) represents a 0.1V reduction. This minor variation falls within typical design margins for LED driver circuits and does not require circuit redesign. The identical test current (150 mA), maximum current (160 mA), and luminous flux (56 lm) ensure functional equivalence in existing designs.

Efficiency Improvement: The substitute parts deliver 124 lm/W compared to 120 lm/W for the original part, representing a 3.3% efficiency gain while maintaining identical lumen output. This improvement results from the LM281BZ+ series optimization and does not affect circuit operation.

Compliance and Certification: All parts maintain RoHS Compliance and identical MSL ratings (2A, 4 Weeks), ensuring compatibility with standard manufacturing and storage protocols. Thermal resistance remains constant at 25°C/W across all variants.

Mechanical Compatibility: Package dimensions, mounting type, viewing angle, and CRI are identical across all parts, confirming direct mechanical and optical interchangeability on existing PCB layouts and in existing optical systems.

Frequently Asked Questions (FAQ)

Q: Can SPMWH3228FD5WAV0SC, SPMWH3228FD5WAVKSC, or SPMWH3228FD5WAVMSC be used as direct replacements for SPMWH3228FD5WAV0S2?

A: Yes. All three substitute parts are parametric equivalents meeting identical electrical, optical, and mechanical specifications. They are direct drop-in replacements for the original part in existing designs.

Q: What is the difference between the three substitute part numbers?

A: The three substitute parts (SPMWH3228FD5WAV0SC, SPMWH3228FD5WAVKSC, SPMWH3228FD5WAVMSC) are all LM281BZ+ series LEDs with identical electrical and optical parameters. The differences in part number suffixes reflect Samsung's internal product tracking and packaging variants, but they deliver equivalent performance in application.

Q: Does the 0.1V forward voltage difference (3.1V vs. 3.0V) require circuit modification?

A: No. The 0.1V reduction in forward voltage falls within standard design margins for LED driver circuits. Existing driver designs will operate correctly with the substitute parts without modification.

Q: Are the substitute parts available in the same packaging format?

A: Yes. All substitute parts use the 1113 (2835 Metric) surface-mount package with identical dimensions (3.50mm L × 2.80mm W × 0.75mm max height), ensuring compatibility with existing PCB layouts and pick-and-place equipment.

Q: Why is the original SPMWH3228FD5WAV0S2 marked as Not For New Designs?

A: The Not For New Designs status indicates that Samsung has transitioned this product to the LM281BZ+ series. The substitute parts represent the current active product line and are recommended for all new designs and ongoing production.

Q: Do the substitute parts have the same color temperature and CRI?

A: Yes. All substitute parts maintain 3000K color temperature and CRI of 80, ensuring identical color characteristics and rendering performance.

Q: What is the inventory status of the substitute parts?

A: SPMWH3228FD5WAV0SC has 737 units in stock, SPMWH3228FD5WAVKSC has 877 units in stock, and SPMWH3228FD5WAVMSC has 1096 units in stock. All are available as new original components.

Q: Are there any thermal or reliability differences between the main part and substitutes?

A: No. Thermal resistance is identical at 25°C/W, and all parts maintain the same MSL rating (2A, 4 Weeks) and RoHS compliance status.
