Substitute Part Grouping Explanation

Substitute parts for SPMWH1228FD5WAW0SE are identified within the Samsung LM281B product family based on strict parameter matching. The substitution criteria are:

Electrical Compatibility:

• Correlated Color Temperature: 2700K (warm white)
• Forward Voltage: 3.1V typical
• Test Current: 150mA
• Maximum Current: 160mA
• Luminous Flux @ 25°C: 63 lm (61–65 lm range)
• Luminous Efficacy: 135 lm/W
• CRI: 80

Mechanical Compatibility:

• Package: 1113 (2835 Metric)
• Mounting: Surface Mount
• Dimensions: 3.50mm × 2.80mm
• Height: 0.75mm maximum

Thermal & Environmental:

• Thermal Resistance: 25°C/W
• RoHS Compliance: Yes
• MSL: 2A (4 Weeks)

The identified substitutes SPMWH1228FD5WAWMS4 and SPMWH1228FD5WAWUS4 share all electrical, mechanical, and thermal parameters with the main part. The primary distinction is product status: the main part (SPMWH1228FD5WAW0SE) carries Active status for new designs, while the substitutes are designated Not For New Designs.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: SPMWH1228FD5WAW0SE is the recommended selection. This part carries Active product status, indicating Samsung's commitment to continued manufacturing and support. It is suitable for incorporation into new product development and long-term production planning.

For Legacy or Existing Designs: SPMWH1228FD5WAWMS4 and SPMWH1228FD5WAWUS4 are available as functional equivalents. Both parts are designated Not For New Designs, indicating they are in mature or end-of-life phases. These substitutes are electrically and mechanically identical to the main part and may be used in existing production runs or maintenance applications where inventory availability is a consideration. SPMWH1228FD5WAWUS4 currently maintains higher inventory levels (40,403 pcs) compared to SPMWH1228FD5WAWMS4 (7,983 pcs).

Compliance Considerations: All three parts are RoHS Compliant and carry identical MSL ratings (2A, 4 Weeks), ensuring compatibility with standard surface-mount assembly processes and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can SPMWH1228FD5WAWMS4 or SPMWH1228FD5WAWUS4 be used as direct replacements for SPMWH1228FD5WAW0SE?

A: Yes. All three parts share identical electrical parameters (3.1V forward voltage, 150mA test current, 63 lm flux, 135 lm/W efficacy), thermal characteristics (25°C/W), and mechanical specifications (2835 package, 3.50 × 2.80 mm, 0.75 mm height). They are functionally interchangeable in circuit design and PCB layout.

Q: What is the difference between the LM281B+ series (main part) and LM281B series (substitutes)?

A: The electrical and thermal performance parameters are identical. The series designation difference reflects Samsung's product lifecycle management. The LM281B+ designation indicates the main part is in Active status for new designs, while LM281B parts are Not For New Designs.

Q: Are there any packaging or handling differences between these parts?

A: No. All three parts use identical Tape & Reel (TR) packaging, MSL rating (2A, 4 Weeks), and surface-mount specifications. Standard SMT assembly and storage procedures apply uniformly.

Q: Which substitute should be selected if inventory is a primary concern?

A: SPMWH1228FD5WAWUS4 has the highest current inventory (40,403 pcs), followed by SPMWH1228FD5WAWMS4 (7,983 pcs). However, for new designs, SPMWH1228FD5WAW0SE (871 pcs in stock) remains the recommended choice due to Active product status.

Q: Do these parts meet RoHS compliance requirements?

A: Yes. All three parts are RoHS Compliant, meeting EU Directive 2011/65/EU and equivalent regulatory standards.

Q: What is the significance of the 2700K color temperature specification?

A: 2700K indicates warm white light output, typical for residential and hospitality lighting applications. All three parts maintain this specification, ensuring consistent color rendering across substitutions.
