Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWH3228FD5WAQMS2 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Color: White, Cool
• CCT: 5700K
• Flux @ 25°C, 150mA: 60lm (58–62lm range)
• Test Current: 150mA
• Maximum Current: 160mA
• CRI: 80
• Viewing Angle: 120°
• Package / Case: 1113 (2835 Metric)
• Size / Dimension: 3.50mm × 2.80mm
• Height - Seated (Max): 0.75mm
• Thermal Resistance: 25°C/W
• RoHS Status: RoHS Compliant
• MSL: 2A (4 Weeks)

Allowable Variation:

• Forward Voltage (Vf) Typical: 3.0V to 3.1V (minor tolerance acceptable)
• Lumens/Watt @ 150mA: 129–133 lm/W (efficiency improvement acceptable)
• Series: LM281BZ or LM281BZ+ (product line evolution)
• Product Status: Active substitutes preferred over end-of-life

The three substitute parts listed below meet all mandatory parameters and represent active product alternatives from Samsung Semiconductor.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

All three substitute parts—SPMWH3228FD5WAQ0SC, SPMWH3228FD5WAQKSC, and SPMWH3228FD5WAQMSC—are classified as Active products and represent direct parametric equivalents to the SPMWH3228FD5WAQMS2. These parts are recommended for new procurement and ongoing production applications.

Key Advantages of Substitutes:

• All substitute parts are Active products, ensuring long-term availability and supply chain stability
• Forward voltage reduction from 3.1V to 3.0V provides improved power efficiency
• Lumens/Watt efficiency increased from 129 lm/W to 133 lm/W across all substitutes
• All parts maintain identical optical, thermal, and mechanical specifications
• All parts retain RoHS compliance and MSL 2A rating

Compliance Considerations:

• All parts are RoHS Compliant and carry identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications
• Moisture sensitivity level remains 2A (4 Weeks) across all parts
• Thermal resistance of 25°C/W is maintained, ensuring equivalent thermal performance in existing designs

Selection Basis: Component selection among the three active substitutes may be based on inventory availability and supply chain logistics. All three parts are electrically and mechanically interchangeable with the main part.

Frequently Asked Questions (FAQ)

Q: Can SPMWH3228FD5WAQ0SC, SPMWH3228FD5WAQKSC, or SPMWH3228FD5WAQMSC be used as direct replacements for SPMWH3228FD5WAQMS2?

A: Yes. All three substitute parts meet the mandatory electrical, optical, and mechanical parameters. They are parametric equivalents with identical package dimensions (3.50mm × 2.80mm), height (0.75mm), color temperature (5700K), luminous flux (60lm at 150mA), viewing angle (120°), and thermal characteristics (25°C/W). The forward voltage reduction from 3.1V to 3.0V and efficiency improvement to 133 lm/W represent enhancements rather than deviations.

Q: What is the difference between LM281BZ and LM281BZ+ series?

A: Both series are part of the Samsung LM281BZ product line. The LM281BZ+ represents an evolved version with improved efficiency (133 lm/W versus 129 lm/W) and slightly lower forward voltage (3.0V versus 3.1V). All other parameters remain identical. The LM281BZ+ is the active product line continuation.

Q: Are there any compatibility concerns with the 2835 metric package?

A: No. All parts use the identical 1113 (2835 Metric) package with matching dimensions and height specifications. PCB footprints, reflow profiles, and pick-and-place equipment settings remain unchanged.

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

A: This designation indicates the SPMWH3228FD5WAQMS2 has reached end-of-life and is no longer recommended for new product development. The three substitute parts carry Active status, confirming their suitability for current and future designs.

Q: Do the substitute parts maintain RoHS compliance?

A: Yes. All three substitute parts are RoHS Compliant with identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications. Regulatory and compliance requirements are fully maintained.

Q: What is the moisture sensitivity level, and does it affect handling?

A: All parts carry MSL 2A (4 Weeks), indicating they must be stored in controlled humidity environments and used within 4 weeks of opening the moisture barrier bag. Handling procedures remain identical across all parts.

Q: Can I mix the three substitute parts in the same production batch?

A: Yes. All three substitute parts are parametrically identical and interchangeable. They can be used interchangeably within the same assembly without functional or performance differences.
