Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWH1228FD5WAVUS2 is determined by the following critical parameters:

Electrical Compatibility:

• Color temperature: 3000K warm white
• CRI: 80
• Test current: 150mA
• Maximum current: 160mA
• Viewing angle: 120°
• Luminous flux: 56lm at 25°C, 150mA test current

Mechanical Compatibility:

• Package type: 1113 (2835 Metric)
• Physical dimensions: 0.138" L x 0.110" W (3.50mm x 2.80mm)
• Height seated maximum: 0.030" (0.75mm)
• Mounting type: Surface Mount

Compliance & Environmental:

• RoHS Compliant
• MSL: 2A (4 Weeks)

The substitute parts SPMWH3228FD5WAV0SC, SPMWH3228FD5WAVKSC, and SPMWH3228FD5WAVMSC are classified as LM281BZ+ series components with Active product status. These parts maintain identical mechanical packaging, electrical performance specifications, and compliance certifications as the original SPMWH1228FD5WAVUS2, with the exception of forward voltage (3.0V typical versus 3.1V) and efficiency (124 lm/W versus 120 lm/W).

Parameter Comparison

Engineering Selection Recommendations

The SPMWH1228FD5WAVUS2 is designated Not For New Designs. For new product development and ongoing production requiring warm white 3000K LEDs in 2835 metric package, the LM281BZ+ series substitutes are recommended based on Active product status.

All three substitute parts (SPMWH3228FD5WAV0SC, SPMWH3228FD5WAVKSC, SPMWH3228FD5WAVMSC) maintain full electrical and mechanical compatibility with the original specification. The forward voltage reduction from 3.1V to 3.0V and efficiency improvement from 120 lm/W to 124 lm/W represent enhanced performance characteristics of the newer LM281BZ+ generation.

All parts carry RoHS Compliant certification and identical MSL rating (2A, 4 Weeks), ensuring equivalent environmental and handling requirements. The substitute parts demonstrate superior inventory availability, with stock levels ranging from 737 to 1096 units compared to 715 units of the original part.

Frequently Asked Questions (FAQ)

Q: Can SPMWH3228FD5WAV0SC, SPMWH3228FD5WAVKSC, and SPMWH3228FD5WAVMSC be used interchangeably with SPMWH1228FD5WAVUS2?

A: Yes. All three substitute parts maintain identical package dimensions (1113/2835 metric), electrical performance (56lm at 150mA, 3000K, 80 CRI, 120° viewing angle), and compliance certifications. The parts are mechanically and electrically compatible for direct substitution in surface mount applications.

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

A: SPMWH3228FD5WAV0SC, SPMWH3228FD5WAVKSC, and SPMWH3228FD5WAVMSC are all LM281BZ+ series components with identical electrical and mechanical specifications. The differences in part numbers reflect manufacturing lot codes or packaging variants. All three parts meet the same performance and compliance requirements.

Q: Why does the forward voltage differ between the main part and substitutes?

A: The SPMWH1228FD5WAVUS2 (LM281B) operates at 3.1V typical forward voltage, while the substitute SPMWH3228FD5WAV series (LM281BZ+) operates at 3.0V typical. This 0.1V reduction represents an improvement in the newer LM281BZ+ generation and does not affect compatibility in standard LED driver circuits designed for 3000K warm white LEDs in this package class.

Q: Are there any handling or storage differences between the main part and substitutes?

A: No. Both the original SPMWH1228FD5WAVUS2 and all substitute parts carry identical MSL rating of 2A (4 Weeks), requiring the same moisture control and storage conditions.

Q: What is the significance of the "Not For New Designs" status on the original part?

A: This designation indicates that the SPMWH1228FD5WAVUS2 (LM281B series) is in end-of-life phase and Samsung recommends using the newer LM281BZ+ series for new product development. The substitute parts with Active status represent the current production generation.

Q: Do all parts require the same PCB footprint?

A: Yes. All parts use the 1113 (2835 metric) package with identical dimensions: 0.138" L x 0.110" W (3.50mm x 2.80mm) and maximum seated height of 0.030" (0.75mm). PCB footprints are directly compatible.
