Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWH3228FD5WAVKS2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Color: White, Warm
• CCT: 3000K
• Package / Case: 1113 (2835 Metric)
• Mounting Type: Surface Mount
• Flux @ 25°C, 150mA: 56 lm (54–58 lm range)
• Current - Test: 150mA
• CRI: 80
• Viewing Angle: 120°
• Thermal Resistance: 25°C/W
• RoHS Status: RoHS Compliant
• MSL: 2A (4 Weeks)

Allowable Variation:

• Voltage - Forward (Typ): 3.0V to 3.1V (within circuit design tolerance)
• Lumens/Watt: 120–124 lm/W (efficiency improvement acceptable)
• Series designation: LM281BZ or LM281BZ+ (same base product family)

The three substitute parts listed below meet all mandatory parameters and fall within allowable variations for forward voltage and efficiency.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are direct parametric equivalents of the SPMWH3228FD5WAVKS2 and are suitable for replacement in existing designs. Selection among the three substitutes should be based on the following criteria:

Product Status: The main part SPMWH3228FD5WAVKS2 carries Not For New Designs status. All three substitute parts (SPMWH3228FD5WAV0SC, SPMWH3228FD5WAVKSC, SPMWH3228FD5WAVMSC) are designated Active, ensuring long-term availability and continued manufacturer support.

Electrical Compatibility: All substitutes operate at 3.0V typical forward voltage compared to the main part's 3.1V. This 0.1V reduction is within standard circuit design tolerance for LED applications and does not require circuit modification. The improved efficiency (124 lm/W versus 120 lm/W) represents a performance enhancement with no negative impact.

Compliance & Certifications: All parts maintain identical RoHS compliance and MSL ratings (2A, 4 Weeks), ensuring equivalent handling and storage requirements. No additional qualification or testing is required for substitution.

Inventory Availability: SPMWH3228FD5WAVMSC offers the highest inventory level (1096 Pcs), followed by SPMWH3228FD5WAVKSC (877 Pcs) and SPMWH3228FD5WAV0SC (737 Pcs). Selection may be influenced by supply chain requirements and lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can SPMWH3228FD5WAV0SC, SPMWH3228FD5WAVKSC, or SPMWH3228FD5WAVMSC be used as direct replacements for SPMWH3228FD5WAVKS2?

A: Yes. All three parts are parametric equivalents meeting identical specifications for color temperature (3000K), luminous flux (56 lm), current rating (150mA test, 160mA max), viewing angle (120°), and package dimensions (2835 metric). The 0.1V reduction in forward voltage and improved efficiency are within acceptable operating parameters.

Q: What is the difference between the three substitute parts?

A: SPMWH3228FD5WAV0SC, SPMWH3228FD5WAVKSC, and SPMWH3228FD5WAVMSC are all LM281BZ+ series parts with identical electrical and mechanical specifications. The differences are limited to part number suffixes and current inventory levels. All three are functionally interchangeable.

Q: Why does the main part have Not For New Designs status?

A: This designation indicates the SPMWH3228FD5WAVKS2 is in end-of-life phase. The substitute parts, all designated Active, are the recommended alternatives for ongoing production and new design implementations.

Q: Are there any circuit modifications required when substituting these parts?

A: No circuit modifications are required. The 0.1V difference in forward voltage (3.0V versus 3.1V) is within standard LED circuit design tolerance and does not necessitate changes to current-limiting resistors or power supply specifications.

Q: Do the substitute parts have the same package and mounting characteristics?

A: Yes. All substitute parts use the 1113 (2835 metric) surface mount package with identical dimensions (3.50mm × 2.80mm) and maximum seated height (0.75mm). PCB footprints and reflow profiles remain unchanged.

Q: What is the MSL rating and how does it affect handling?

A: All parts, including the main part and substitutes, carry MSL 2A rating with a 4-week floor life. This requires standard moisture control during storage and handling, with baking required if the 4-week limit is exceeded before reflow soldering.

Q: Are all parts RoHS compliant?

A: Yes. The main part and all three substitute parts are RoHS compliant, meeting regulatory requirements for hazardous substance restrictions.
