Substitute Part Grouping Explanation

Substitution of the SPMWH1228FD5WAP0S2 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Color: White, Cool (6500K CCT)
• Package / Case: 1113 (2835 Metric)
• Mounting Type: Surface Mount
• Viewing Angle: 120°
• CRI: 80
• Test Current: 150mA
• Maximum Current: 160mA
• Thermal Resistance: 25°C/W
• MSL: 2A (4 Weeks)

Substitution Categories:

Direct Manufacturer Equivalent: SPMWH1228FD5WAP0SA is a direct equivalent from Samsung Semiconductor. It shares the identical base product number (SPMWH1228), package, electrical ratings, and mechanical dimensions. The primary difference is the series designation (LM281B+ versus LM281B) and active product status. Flux output at 25°C is 60 lm (58–62 lm range) with 129 lm/W efficiency, representing a minor performance improvement within acceptable tolerance.

Parametric Equivalents: SPMWH3228FD5WAP0SC, SPMWH3228FD5WAPKSC, and SPMWH3228FD5WAPMSC are parametric equivalents from the LM281BZ+ series. These parts maintain identical package geometry, color temperature, CRI, viewing angle, current ratings, and thermal characteristics. The forward voltage is 3.0V (versus 3.1V), and flux output is 59 lm (57–61 lm range) with 131 lm/W efficiency. These parts are functionally compatible within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): SPMWH1228FD5WAP0SA is the recommended direct substitute. It maintains the identical base product number, package, and electrical specifications. The part carries Active product status, ensuring long-term availability and supply chain stability. RoHS3 compliance provides enhanced environmental certification. Flux output of 60 lm represents a 1.7% improvement over the original 59 lm specification, remaining within acceptable tolerance bands.

For Parametric Substitution: SPMWH3228FD5WAP0SC, SPMWH3228FD5WAPKSC, and SPMWH3228FD5WAPMSC are functionally compatible alternatives. All three parts are Active status products with RoHS compliance. The forward voltage reduction from 3.1V to 3.0V results in lower power dissipation (0.45W versus 0.465W at 150mA). Efficiency improvement to 131 lm/W (versus 127 lm/W) provides superior luminous efficacy. These parts are suitable for applications where the 0.1V voltage differential and improved efficiency are acceptable within circuit design margins.

Compliance Considerations: All substitute parts maintain MSL 2A (4 Weeks) moisture sensitivity and identical thermal resistance characteristics. RoHS compliance is confirmed across all options. No additional qualification or testing is required based on the provided certifications.

Frequently Asked Questions (FAQ)

Q: Can SPMWH1228FD5WAP0SA be used as a direct drop-in replacement for SPMWH1228FD5WAP0S2?

A: Yes. SPMWH1228FD5WAP0SA is a direct manufacturer equivalent with identical package geometry (1113/2835), electrical ratings (3.1V, 150mA test current, 160mA maximum), and mechanical dimensions (3.50mm × 2.80mm, 0.75mm height). The flux output of 60 lm is within the acceptable tolerance range and represents a minor performance improvement.

Q: What is the difference between the direct equivalent and parametric equivalents?

A: The direct equivalent (SPMWH1228FD5WAP0SA) shares the identical base product number and series designation (LM281B+). Parametric equivalents (SPMWH3228 series, LM281BZ+) differ in forward voltage (3.0V versus 3.1V) and efficiency (131 lm/W versus 127 lm/W) but maintain all critical package, color, and thermal specifications. Both categories are electrically and mechanically compatible.

Q: Will the 0.1V forward voltage difference between 3.1V and 3.0V affect circuit operation?

A: The 0.1V difference is within typical circuit design margins for LED applications. This reduction results in lower power dissipation (approximately 3% less) and improved efficiency. Circuit designs using current-limiting resistors or constant-current drivers will accommodate this variation without modification.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts use identical 1113 (2835 metric) surface mount packages with matching dimensions and height specifications. The direct equivalent (SPMWH1228FD5WAP0SA) is available in Tape & Reel (TR) packaging. Parametric equivalents do not specify packaging format in the provided data but maintain identical physical dimensions for PCB assembly compatibility.

Q: What is the inventory status of substitute parts?

A: SPMWH1228FD5WAP0SA has 81,037 units in stock. Parametric equivalents have lower inventory: SPMWH3228FD5WAP0SC (1,114 units), SPMWH3228FD5WAPKSC (614 units), and SPMWH3228FD5WAPMSC (973 units). The direct equivalent offers superior supply availability.

Q: Are there any RoHS compliance differences between the options?

A: SPMWH1228FD5WAP0SA carries ROHS3 certification, representing enhanced environmental compliance. All parametric equivalents maintain RoHS compliance. Both certifications satisfy standard environmental requirements; ROHS3 provides additional assurance for regulated markets.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, within the specified electrical and mechanical parameters. The direct equivalent (SPMWH1228FD5WAP0SA) requires no design changes. Parametric equivalents require verification that the 0.1V forward voltage reduction is acceptable within the circuit's current-limiting design. All parts maintain identical thermal resistance (25°C/W) and moisture sensitivity (MSL 2A).
