Substitute Part Grouping Explanation

Substitution of the SPMWH1228FD5WAPUS3 is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Color Temperature: 6500K (cool white)
• Color: White, Cool
• Package / Case: 1113 (2835 Metric)
• Flux @ 25°C, 150mA: 63 lm (61–65 lm range)
• Test Current: 150mA
• Viewing Angle: 120° (±5° tolerance acceptable)
• CRI: 80
• Forward Voltage (Vf): 3.0–3.1V range
• Lumens/Watt: 135–142 lm/W range
• Mounting Type: Surface Mount
• RoHS Compliance: Required

Parametric Equivalent Parts (SPMWH3228FD5WAP0SE, SPMWH3228FD5WAPKSE, SPMWH3228FD5WAPMSE) meet all primary criteria with identical electrical performance and package specifications. These parts are Samsung LM281BZ+ series variants with Active product status, offering direct functional replacement.

Similar Parts (BXEN-65E-21M-3A-00-0-0) from Bridgelux meet core electrical and optical parameters within acceptable engineering tolerances, with minor variations in viewing angle (118° vs. 120°) and physical dimensions within the 2835 package class.

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalent Selection (SPMWH3228FD5WAP0SE, SPMWH3228FD5WAPKSE, SPMWH3228FD5WAPMSE):

These Samsung LM281BZ+ variants are direct functional replacements for the SPMWH1228FD5WAPUS3. All three parts maintain identical optical output (63 lm @ 25°C, 150mA), color temperature (6500K), CRI (80), and package specifications (1113/2835 metric). The forward voltage reduction from 3.1V to 3.0V represents improved efficiency (140 lm/W vs. 135 lm/W) while remaining within standard circuit design tolerances. All three variants carry Active product status, ensuring long-term availability and supply chain continuity. RoHS compliance and MSL ratings are identical to the main part. Selection among these three variants depends on packaging and distribution channel requirements, as electrical and optical performance are equivalent.

Similar Part Selection (BXEN-65E-21M-3A-00-0-0):

The Bridgelux BXEN-65E-21M-3A-00-0-0 is a cross-manufacturer alternative meeting core electrical and optical specifications. Flux output (66 lm typical) is within acceptable tolerance of the 63 lm specification. Forward voltage (3.1V) and test current (150mA) match the main part exactly. Viewing angle (118°) differs by 2° from the 120° specification but remains within typical application tolerances for 2835 package class LEDs. Lumens/watt efficiency (142 lm/W) exceeds the main part. The part carries Active status and ROHS3 compliance. MSL rating (3, 168 hours) differs from the main part (2A, 4 weeks) and requires evaluation against storage and assembly process conditions. Physical dimensions vary slightly within the 2835 package class (2.74mm × 3.40mm vs. 3.50mm × 2.80mm) and must be verified for PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can SPMWH3228FD5WAP0SE, SPMWH3228FD5WAPKSE, and SPMWH3228FD5WAPMSE be used interchangeably with SPMWH1228FD5WAPUS3?

A: Yes. All three Samsung LM281BZ+ variants are parametric equivalents with identical flux output (63 lm @ 25°C, 150mA), color temperature (6500K), CRI (80), package (1113/2835), and thermal characteristics. The 0.1V reduction in forward voltage (3.0V vs. 3.1V) is within standard circuit design tolerance and improves efficiency. All three carry Active product status.

Q: What is the difference between the three Samsung LM281BZ+ variants?

A: SPMWH3228FD5WAP0SE, SPMWH3228FD5WAPKSE, and SPMWH3228FD5WAPMSE are electrically and optically identical. Differences exist only in packaging designation and distribution channel. Selection should be based on supplier availability and packaging requirements for your assembly process.

Q: Can the Bridgelux BXEN-65E-21M-3A-00-0-0 replace the SPMWH1228FD5WAPUS3?

A: The Bridgelux part meets core electrical and optical parameters within engineering tolerance. Flux output (66 lm) is 4.8% above specification but acceptable. Viewing angle (118° vs. 120°) represents a 1.7% difference. Physical dimensions vary within the 2835 package class and must be verified for PCB layout compatibility. MSL rating (3, 168 hours) differs and requires evaluation against your assembly process conditions.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution is determined by: color temperature (6500K), color (white, cool), package (1113/2835 metric), flux output (63 lm ±3 lm @ 25°C, 150mA), test current (150mA), viewing angle (120° ±2°), CRI (80), forward voltage (3.0–3.1V), and RoHS compliance. Deviations outside these ranges require circuit design re-evaluation.

Q: Does the 0.1V forward voltage difference between the main part and Samsung LM281BZ+ variants affect circuit design?

A: No. The 0.1V reduction (3.1V to 3.0V) is within standard tolerance for LED circuit design and improves efficiency. Existing current-limiting resistor values and power supply specifications remain valid. This change is transparent to the application.

Q: What is the impact of the different MSL ratings between the main part and Bridgelux alternative?

A: The main part carries MSL 2A (4 weeks), while the Bridgelux part carries MSL 3 (168 hours). MSL 3 allows longer storage at higher humidity before reflow assembly. If your assembly process includes extended storage periods or high-humidity environments, the Bridgelux part's MSL 3 rating may provide operational advantages. Verify against your specific storage and assembly conditions.

Q: Are all substitute parts RoHS compliant?

A: Yes. The main part and all three Samsung LM281BZ+ variants carry RoHS Compliant certification. The Bridgelux alternative carries ROHS3 Compliant certification. All parts meet regulatory requirements for RoHS-restricted substance limits.

Q: Can physical dimension differences between the Bridgelux part and Samsung parts affect PCB assembly?

A: Yes. The Bridgelux BXEN-65E-21M-3A-00-0-0 has dimensions of 2.74mm L × 3.40mm W, while Samsung parts are 3.50mm L × 2.80mm W. Both fit the 1113 (2835 metric) package class, but PCB pad layout and solder paste stencil design may require adjustment. Verify pad dimensions and reflow profile compatibility before production use.
