Parameter Comparison

Engineering Selection Recommendations

Both the SPMWH1221FD5GBTMSA and SPMWH1221FD5GBT0SA are classified as "Not For New Designs" by Samsung Semiconductor. This status indicates both components have reached end-of-life in the manufacturer's active product line.

Selection Basis:

The SPMWH1221FD5GBT0SA is a direct parametric equivalent to the SPMWH1221FD5GBTMSA. All electrical specifications, mechanical dimensions, thermal characteristics, and compliance certifications are identical. Both components are RoHS Compliant and carry identical Moisture Sensitivity Level (MSL) ratings of 2A with a 4-week floor life requirement.

For applications currently using SPMWH1221FD5GBTMSA, the SPMWH1221FD5GBT0SA provides full functional and physical interchangeability. The difference between these part numbers reflects internal Samsung manufacturing or packaging revision codes (suffix "MSA" versus "0SA") rather than electrical or mechanical divergence.

Inventory Consideration:

Current stock availability shows SPMWH1221FD5GBTMSA at 34,900 units and SPMWH1221FD5GBT0SA at 16,508 units. Both variants remain available through authorized distribution channels.

Frequently Asked Questions (FAQ)

Q: Are SPMWH1221FD5GBTMSA and SPMWH1221FD5GBT0SA electrically interchangeable?

A: Yes. Both components share identical electrical specifications: 6.3V forward voltage, 150mA test current, 110 lm luminous flux at 25°C, 116 lm/W efficiency, 4000K CCT, and 80 CRI. They operate within the same current range (150mA nominal, 160mA maximum) and produce equivalent light output.

Q: Can these LEDs be used interchangeably in PCB designs?

A: Yes. Both parts use the identical 1113 (2835 Metric) surface-mount package with matching footprint dimensions (3.50mm × 2.80mm) and maximum seated height (0.75mm). No PCB layout modifications are required for substitution.

Q: What does the "Not For New Designs" status mean?

A: This designation indicates both components have reached end-of-life status in Samsung's product portfolio. While existing inventory remains available for purchase, Samsung does not recommend these parts for new product development. Organizations should evaluate alternative current-generation LED options for future designs.

Q: Are there any compliance differences between these two part numbers?

A: No. Both components are RoHS Compliant, carry identical MSL ratings (2A, 4 Weeks), and share the same ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: What is the significance of the different suffixes (MSA vs. 0SA)?

A: The suffix variation reflects internal Samsung manufacturing or packaging revision codes. These differences do not affect electrical performance, mechanical compatibility, or compliance status. Both variants are functionally equivalent.

Q: What thermal management considerations apply to these LEDs?

A: Both components have a thermal resistance of 15°C/W. This specification defines the temperature rise per watt of power dissipation. At 150mA and 6.3V, power dissipation is approximately 0.945W, resulting in a junction temperature rise of approximately 14.2°C above ambient conditions.

Q: Are moisture handling procedures identical for both parts?

A: Yes. Both components carry MSL 2A rating, requiring storage at ≤30°C and ≤60% relative humidity with a maximum floor life of 4 weeks after bag opening. Identical moisture control and reflow procedures apply to both part numbers.
