Substitute Part Grouping Explanation

Substitution eligibility for the SPMWH3228FD5WAVMS4 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Color: White, Warm (3000K CCT)
• Flux @ 25°C, 150mA: 64 lm (62–66 lm range)
• Forward Voltage (Vf) Typical: 3.1V or 3.0V
• Test Current: 150mA
• Maximum Current: 160mA
• CRI: 80
• Viewing Angle: 120°
• Package / Case: 1113 (2835 Metric)
• Size / Dimension: 0.138" L × 0.110" W (3.50mm × 2.80mm)
• Height - Seated (Max): 0.030" (0.75mm)
• Thermal Resistance: 25°C/W
• Mounting Type: Surface Mount
• RoHS Status: RoHS Compliant
• MSL: 2A (4 Weeks)

Substitute Categories:

Category A – LM281B Series (Not For New Designs): Parts SPMWH1228FD5WAV0S4, SPMWH1228FD5WAVMS4, and SPMWH1228FD5WAVUS4 are parametric equivalents with identical electrical and mechanical specifications. These parts differ only in packaging suffix designations (0S4, MS4, US4) representing regional or supply chain variants. All maintain 3.1V forward voltage and 138 lm/W efficiency.

Category B – LM281BZ+ Series (Active Status): Parts SPMWH3228FD5WAV0SG, SPMWH3228FD5WAVKSG, and SPMWH3228FD5WAVMSG represent active product alternatives with improved forward voltage (3.0V typical) and higher efficiency (142 lm/W). These parts maintain identical flux output, CRI, viewing angle, and package dimensions. Packaging format differs (no TR designation provided), and product status is Active rather than Not For New Designs.

Parameter Comparison

Engineering Selection Recommendations

For Existing Production Support: The LM281B series substitutes (SPMWH1228FD5WAV0S4, SPMWH1228FD5WAVMS4, SPMWH1228FD5WAVUS4) provide direct parametric equivalence to SPMWH3228FD5WAVMS4. These parts maintain identical electrical performance (3.1V forward voltage, 138 lm/W efficiency) and mechanical compatibility (2835 package, 120° viewing angle). Selection among these three variants depends on regional supply chain requirements, as indicated by packaging suffix designations (0S4, MS4, US4). All three carry RoHS Compliant certification and 2A MSL rating.

For New Design Initiatives: The LM281BZ+ series (SPMWH3228FD5WAV0SG, SPMWH3228FD5WAVKSG, SPMWH3228FD5WAVMSG) represents the active product alternative with improved efficiency (142 lm/W versus 138 lm/W) and lower forward voltage (3.0V versus 3.1V). These parts maintain identical flux output (64 lm), CRI (80), and mechanical dimensions. Active product status indicates ongoing Samsung support and availability. Selection among these three variants follows the same regional supply chain logic as the LM281B series.

Compliance Considerations: All substitute parts maintain RoHS Compliant status and 2A MSL (4 Weeks) moisture sensitivity rating, ensuring compatibility with standard PCB assembly and storage protocols. Thermal resistance remains constant at 25°C/W across all alternatives, supporting equivalent thermal design calculations.

Frequently Asked Questions (FAQ)

Q: Can SPMWH1228FD5WAVMS4 directly replace SPMWH3228FD5WAVMS4 in existing designs?

A: Yes. Both parts share identical electrical specifications (3.1V forward voltage, 64 lm flux at 150mA, 138 lm/W efficiency), CRI (80), viewing angle (120°), and mechanical package dimensions (2835 metric, 0.138" × 0.110" × 0.030" max height). Surface mount compatibility and thermal characteristics are equivalent. The primary difference is product status designation; SPMWH1228FD5WAVMS4 carries "Not For New Designs" status.

Q: What is the difference between the LM281B and LM281BZ+ series substitutes?

A: The LM281BZ+ series (SPMWH3228FD5WAV0SG, SPMWH3228FD5WAVKSG, SPMWH3228FD5WAVMSG) offers improved efficiency (142 lm/W versus 138 lm/W) and lower forward voltage (3.0V versus 3.1V) while maintaining identical flux output (64 lm), CRI (80), and package dimensions. LM281BZ+ parts carry Active product status, indicating ongoing manufacturer support. LM281B parts are designated "Not For New Designs."

Q: Are the packaging suffix variants (0S4, MS4, US4) electrically interchangeable?

A: Yes. The suffix designations (0S4, MS4, US4) represent regional or supply chain packaging variants within the same series. All three variants of SPMWH1228FD5WAV maintain identical electrical and mechanical specifications. Selection should be based on regional availability and supply chain requirements.

Q: What are the thermal design implications when substituting these parts?

A: All substitute parts maintain 25°C/W thermal resistance. Thermal design calculations remain unchanged. PCB layout, solder pad design, and thermal management strategies do not require modification when substituting between listed alternatives.

Q: Do all substitute parts meet the same moisture sensitivity requirements?

A: Yes. All substitute parts carry MSL 2A (4 Weeks) rating, indicating identical moisture sensitivity classification. Storage, handling, and reflow procedures remain consistent across all alternatives.

Q: Which substitute should be selected for new product development?

A: The LM281BZ+ series (SPMWH3228FD5WAV0SG, SPMWH3228FD5WAVKSG, SPMWH3228FD5WAVMSG) is recommended for new designs due to Active product status, improved efficiency (142 lm/W), and lower forward voltage (3.0V). These characteristics provide better long-term availability and superior power efficiency compared to "Not For New Designs" alternatives.

Q: Are there any viewing angle or CRI differences among the substitutes?

A: No. All substitute parts maintain 120° viewing angle and CRI 80. Optical performance characteristics are identical across all alternatives.
