SPMWH3228FD5WAVKSE LED Equivalent & Substitute Parts

Part Overview

The SPMWH3228FD5WAVKSE is a Samsung Semiconductor surface-mount LED lighting component featuring the LM281BZ+ series with warm white 3000K color temperature. This part is classified as Active product status and is suitable for new designs. The component operates at 3V forward voltage with 150mA test current, delivering 60lm luminous flux at 25°C with a color rendering index (CRI) of 80. The 2835 metric package (1113) provides a compact form factor measuring 3.50mm × 2.80mm with 0.75mm maximum seated height.

Substitute parts are necessary when the primary part experiences supply constraints, inventory limitations, or when design flexibility across packaging variants is required. The identified substitutes maintain electrical and photometric equivalence while utilizing the LM281B series, which differs in forward voltage specification and product status classification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWH3228FD5WAVKSE is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Color: White, Warm (3000K CCT)
• Luminous Flux @ 25°C, 150mA: 60lm (58–62lm range)
• Test Current: 150mA
• Maximum Current: 160mA
• CRI: 80
• Viewing Angle: 120°

Mechanical & Package Equivalence Criteria:

• Package / Case: 1113 (2835 Metric)
• Dimensions: 3.50mm × 2.80mm
• Height – Seated (Max): 0.75mm
• Mounting Type: Surface Mount
• Thermal Resistance: 25°C/W

Identified Substitutes: The three substitute parts (SPMWH1228FD5WAV0S3, SPMWH1228FD5WAVMS3, SPMWH1228FD5WAVUS3) are classified as parametric equivalents. These parts utilize the LM281B series instead of LM281BZ+ and operate at 3.1V forward voltage (compared to 3.0V for the main part). All other electrical and mechanical parameters remain identical. The substitutes are available in Tape & Reel (TR) packaging and carry "Not For New Designs" product status.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection: The SPMWH3228FD5WAVKSE is the recommended choice for new designs. This part carries Active product status, indicating full manufacturer support and continued availability. The LM281BZ+ series designation and 3.0V forward voltage specification provide the baseline electrical performance for this product family.

Substitute Part Selection Criteria:

The three substitute parts (SPMWH1228FD5WAV0S3, SPMWH1228FD5WAVMS3, SPMWH1228FD5WAVUS3) are classified as "Not For New Designs" and should be used only when the primary part is unavailable. These substitutes are electrically and mechanically compatible with the main part, with the following considerations:

1. Forward Voltage Difference: Substitute parts operate at 3.1V typical forward voltage compared to 3.0V for the main part. Circuit designs must accommodate this 0.1V increase in voltage drop.

2. Luminous Efficacy: Substitute parts deliver 129 lm/W compared to 133 lm/W for the main part. This represents a 3% reduction in luminous efficacy at the test current of 150mA.

3. Packaging Variant: All substitute parts are supplied in Tape & Reel (TR) packaging, whereas the main part packaging specification is not explicitly stated. Verify packaging compatibility with assembly equipment.

4. Compliance: All parts maintain RoHS Compliance and identical MSL (2A, 4 Weeks) ratings, ensuring equivalent environmental and handling requirements.

5. Inventory Availability: Substitute parts demonstrate higher inventory levels (2,401–32,929 units) compared to the main part (940 units), providing supply chain flexibility when primary part allocation is constrained.

Frequently Asked Questions (FAQ)

Q1: Can SPMWH1228FD5WAVUS3 be used as a direct replacement for SPMWH3228FD5WAVKSE?

A: SPMWH1228FD5WAVUS3 is a parametric equivalent substitute. Direct replacement is possible with circuit design verification. The 0.1V increase in forward voltage (3.1V vs. 3.0V) must be accommodated in the LED driver or power supply design. The 3% reduction in luminous efficacy (129 vs. 133 lm/W) may affect overall system brightness output.

Q2: What is the difference between the three substitute parts?

A: SPMWH1228FD5WAV0S3, SPMWH1228FD5WAVMS3, and SPMWH1228FD5WAVUS3 are electrically and mechanically identical. The suffix designations (0S3, MS3, US3) indicate different packaging or regional supply variants. All three parts are available from Samsung Semiconductor and carry identical electrical specifications, CRI, color temperature, and thermal characteristics.

Q3: Why is the main part SPMWH3228FD5WAVKSE marked as Active while substitutes are marked as Not For New Designs?

A: Product status reflects manufacturer lifecycle classification. Active status indicates the main part is in full production with ongoing support for new designs. "Not For New Designs" status for substitute parts indicates these are legacy or transitional products. For new product development, the SPMWH3228FD5WAVKSE should be specified. Substitutes are appropriate for existing designs requiring component replacement or when primary part availability is limited.

Q4: Are there any thermal or reliability differences between the main part and substitutes?

A: Thermal resistance (25°C/W) and MSL rating (2A, 4 Weeks) are identical across all parts. No thermal or reliability differences are specified in the provided parameters. Both the main part and substitutes are suitable for equivalent thermal management and storage conditions.

Q5: What packaging differences exist between the main part and substitutes?

A: The main part SPMWH3228FD5WAVKSE does not specify packaging format in the provided data. All three substitute parts are supplied in Tape & Reel (TR) packaging. Verify that TR packaging is compatible with your assembly process before selecting a substitute.

Q6: Can substitutes be mixed with the main part in the same production batch?

A: Mixing is not recommended without circuit design verification. The 0.1V forward voltage difference between the main part (3.0V) and substitutes (3.1V) may result in uneven current distribution in parallel LED configurations or inconsistent brightness in series strings. If mixing is necessary, implement individual current-limiting resistors or use constant-current LED drivers to ensure uniform performance.

Q7: Which substitute part has the highest inventory availability?

A: SPMWH1228FD5WAVUS3 has the highest inventory level at 32,929 units. SPMWH1228FD5WAVMS3 has 3,758 units, and SPMWH1228FD5WAV0S3 has 2,401 units. For supply chain continuity, SPMWH1228FD5WAVUS3 is the preferred substitute when primary part allocation is constrained.

Q8: Do all parts meet RoHS compliance requirements?

A: Yes. The main part SPMWH3228FD5WAVKSE and all three substitute parts (SPMWH1228FD5WAV0S3, SPMWH1228FD5WAVMS3, SPMWH1228FD5WAVUS3) are RoHS Compliant. All parts carry identical MSL (2A, 4 Weeks) moisture sensitivity ratings and are suitable for equivalent handling and storage protocols.
