SPMWH1228FD5WAWMSC LED Equivalent & Substitute Parts

Part Overview

The SPMWH1228FD5WAWMSC is a Samsung Semiconductor LM281B+ warm white LED in 2835 metric package (1113 case code) designed for surface mount lighting applications. This component operates at 3.1V forward voltage with 150mA test current, delivering 59 lumens at 25°C with a color temperature of 2700K and 80 CRI. The part is currently in Active product status with 703 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when inventory levels require alternative sourcing, or when design flexibility permits selection from equivalent alternatives within the same electrical and mechanical parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWH1228FD5WAWMSC is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Color Temperature: 2700K (warm white)
• Forward Voltage: 3.1V nominal
• Test Current: 150mA
• Maximum Current: 160mA
• Luminous Flux @ 25°C: 59 lm (range 57–61 lm)
• Color Rendering Index: 80
• Lumens/Watt: 127 lm/W

Mechanical Parameters:

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

Compliance Parameters:

• RoHS Compliant status
• Moisture Sensitivity Level: 2A (4 Weeks)

The substitute parts SPMWH1228FD5WAWMS3 and SPMWH1228FD5WAWUS3 maintain identical electrical performance and mechanical compatibility. The primary distinction is product status: the main part (SPMWH1228FD5WAWMSC) is Active, while substitutes are designated Not For New Designs. Series designation differs (LM281B+ versus LM281B), reflecting internal Samsung product line evolution without affecting functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (SPMWH1228FD5WAWMSC): Select this part for new designs and applications requiring long-term component availability. Active product status ensures continued manufacturing support and supply chain stability. This part is the preferred choice for production designs with extended lifecycle requirements.

Substitute Part Selection (SPMWH1228FD5WAWMS3 or SPMWH1228FD5WAWUS3): These parts are electrically and mechanically equivalent and may be used as direct replacements in existing designs or for immediate fulfillment when primary part inventory is constrained. Both substitutes are designated Not For New Designs, indicating Samsung's recommendation to use the LM281B+ series (SPMWH1228FD5WAWMSC) for new product development.

Compliance Considerations: All three parts maintain identical RoHS compliance and MSL ratings (2A, 4 Weeks), ensuring compatibility with standard surface mount assembly processes and storage requirements. No additional handling or qualification is required when substituting between these parts.

Inventory Availability: SPMWH1228FD5WAWUS3 offers the highest inventory level (19,696 units), followed by SPMWH1228FD5WAWMS3 (7,277 units). Selection between substitutes may be driven by supply chain logistics and lead time requirements.

Frequently Asked Questions (FAQ)

Q: Can SPMWH1228FD5WAWMS3 or SPMWH1228FD5WAWUS3 be used as direct replacements for SPMWH1228FD5WAWMSC in existing production?

A: Yes. All three parts share identical electrical parameters (3.1V forward voltage, 150mA test current, 59 lm flux, 2700K color temperature, 80 CRI) and mechanical specifications (2835 package, 3.50 × 2.80 mm footprint, 0.75 mm height). They are functionally interchangeable at the circuit and PCB assembly level.

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

A: The series designation reflects Samsung's internal product line classification. Both series maintain identical electrical performance and mechanical compatibility. The LM281B+ (SPMWH1228FD5WAWMSC) is the current Active product, while LM281B variants are designated Not For New Designs.

Q: Are there any thermal or reliability differences between these parts?

A: No. All three parts specify identical thermal resistance (25°C/W) and moisture sensitivity levels (2A, 4 Weeks). Thermal performance and reliability characteristics are equivalent across the group.

Q: Can these parts be mixed in the same production batch or assembly?

A: Yes. Identical package dimensions, mounting type, and electrical characteristics permit interchangeability within a single assembly. However, design documentation should specify the primary part number (SPMWH1228FD5WAWMSC) with approved substitutes listed separately for traceability.

Q: What is the significance of the "Not For New Designs" status on the substitute parts?

A: This designation indicates that Samsung recommends using SPMWH1228FD5WAWMSC for new product development to ensure long-term supply continuity. Substitute parts may be used for legacy design support, inventory management, or immediate fulfillment but should not be selected as the primary component for new designs.

Q: Are there any differences in packaging or tape reel specifications?

A: All three parts are supplied in Tape & Reel (TR) packaging with identical supplier device package designation (2835). No differences in packaging format or reel specifications exist.

Q: What storage and handling requirements apply to these parts?

A: All parts carry MSL rating 2A (4 Weeks), requiring storage at controlled temperature and humidity (typically ≤30°C, ≤60% RH) with a maximum floor life of 4 weeks after bag opening. Standard surface mount assembly processes and ESD precautions apply.
