Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWH3228FD5WAP0S3 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Color: White, Cool
• CCT: 6500K
• Flux @ 25°C, 150mA: 63 lm (61–65 lm range)
• Test Current: 150mA
• Maximum Current: 160mA
• CRI: 80
• Viewing Angle: 120°
• Package / Case: 1113 (2835 Metric)
• Size: 3.50 × 2.80 mm
• Height (Seated Max): 0.75 mm
• Thermal Resistance: 25°C/W
• RoHS Status: RoHS Compliant
• MSL: 2A (4 Weeks)

Allowable Variation:

• Forward Voltage (Vf): The main part specifies 3.1V typical. Substitute parts with 3.0V typical are acceptable within the LM281BZ+ series evolution, as this represents an improved generation with enhanced efficiency (140 lm/W vs. 135 lm/W).
• Product Status: Active substitutes are preferred over Not For New Designs status.
• Base Product Number: All substitutes share SPMWH3228 base designation.

All three substitute parts meet these criteria and belong to the LM281BZ+ active product line.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

The three substitute parts—SPMWH3228FD5WAP0SE, SPMWH3228FD5WAPKSE, and SPMWH3228FD5WAPMSE—are all active products in the LM281BZ+ series. These are recommended for new designs and ongoing production requiring cool white 6500K LEDs in 2835 metric packages.

Efficiency Improvement:

All substitute parts deliver 140 lm/W compared to the main part's 135 lm/W, representing a 3.7% efficiency gain while maintaining identical luminous flux (63 lm) and color characteristics. This improvement results from the forward voltage reduction from 3.1V to 3.0V.

Compliance and Certification:

All parts maintain RoHS compliance and identical MSL ratings (2A, 4 Weeks), ensuring compatibility with standard surface mount assembly processes and storage requirements.

Inventory Availability:

SPMWH3228FD5WAP0SE: 911 pcs SPMWH3228FD5WAPKSE: 716 pcs SPMWH3228FD5WAPMSE: 727 pcs

All three substitutes are available in sufficient quantities for production requirements.

Frequently Asked Questions (FAQ)

Q: Can SPMWH3228FD5WAP0SE, SPMWH3228FD5WAPKSE, or SPMWH3228FD5WAPMSE be used as direct replacements for SPMWH3228FD5WAP0S3?

A: Yes. All three substitute parts are parametrically equivalent across all critical electrical and mechanical specifications. The forward voltage difference (3.0V vs. 3.1V) is within acceptable design margins for 6500K cool white LED applications and results in improved efficiency. All parts share identical package dimensions, thermal characteristics, and compliance certifications.

Q: What is the significance of the LM281BZ+ designation on substitute parts?

A: The LM281BZ+ represents an active product generation of the LM281BZ series. The main part (LM281BZ) is marked Not For New Designs, while all substitutes are active products. This indicates Samsung continues to support and manufacture the LM281BZ+ line for current and future applications.

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

A: No. All parts share identical thermal resistance (25°C/W), package type (1113 / 2835 metric), dimensions (3.50 × 2.80 mm), and maximum seated height (0.75 mm). Surface mount assembly processes and thermal management designs require no modification.

Q: How does the 0.1V forward voltage reduction affect circuit design?

A: The reduction from 3.1V to 3.0V typical forward voltage is a minor variation within standard LED design tolerances. For series-connected LED strings or current-limited driver circuits, this 3.2% reduction may result in slightly lower power dissipation in series resistors or improved driver efficiency. No circuit redesign is required for standard applications.

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

A: Yes. All substitute parts maintain 6500K CCT and 80 CRI, ensuring identical color temperature and color rendering characteristics. Luminous flux at 25°C and 150mA is specified as 63 lm (61–65 lm range) for all parts, confirming color consistency within manufacturing tolerances.

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

A: The three substitute parts (SPMWH3228FD5WAP0SE, SPMWH3228FD5WAPKSE, SPMWH3228FD5WAPMSE) are parametrically identical. Differences in part number suffixes reflect Samsung's internal packaging or distribution designations. All three are functionally equivalent for engineering purposes.

Q: Are moisture sensitivity levels identical across all parts?

A: Yes. All parts, including the main part and all three substitutes, are rated MSL 2A (4 Weeks). This means components must be used within 4 weeks of bag opening under controlled humidity conditions (≤30% RH at 23°C). Standard surface mount assembly handling procedures apply uniformly.

Q: Is RoHS compliance maintained across all substitute parts?

A: Yes. All substitute parts are RoHS Compliant, matching the main part's compliance status. No additional environmental or regulatory considerations are introduced by substitution.
