SPMWHT541MP5WARSS4 LED Equivalent & Substitute Parts

Part Overview

The SPMWHT541MP5WARSS4 is an active Samsung Semiconductor LM561B Plus white LED in 5630 surface mount package, rated for cool white 5000K color temperature with 65mA test current and 2.95V forward voltage. This component is used in general illumination and backlighting applications requiring high efficiency and consistent color rendering. Substitute parts are necessary to accommodate different packaging formats, inventory availability, and supply chain requirements while maintaining identical electrical and optical performance.

Key Parameters

Substitute Part Grouping Explanation

All substitute parts maintain identical electrical and optical parameters as the main part SPMWHT541MP5WARSS4. Substitution is determined by the following criteria:

Electrical Equivalence: All parts share the same LM561B Plus series designation, 5000K color temperature, 34lm flux output at 65mA test current, 2.95V forward voltage, 177 lm/W efficiency, 80 CRI, 120° viewing angle, and 180mA maximum current rating.

Mechanical Compatibility: All parts use identical 4-SMD flat lead package in 5630 form factor with 5.00mm x 3.00mm x 0.80mm maximum height, enabling direct PCB footprint compatibility.

Regulatory Compliance: All parts maintain ROHS3 compliance and EAR99 export classification.

Differentiation Factor: Packaging format only. Substitutes differ in supply format (Tape & Reel, Cut Tape, or Cut Tape with Digi-Reel) and thermal resistance specification (14°C/W vs 15°C/W), with no impact on functional performance.

Parameter Comparison

Engineering Selection Recommendations

All four parts are active products with ROHS3 compliance and identical electrical and optical specifications. Selection between SPMWHT541MP5WARSS4 and its substitutes is based solely on packaging format requirements and supply chain availability:

SPMWHT541MP5WARSS4 (Tape & Reel): Primary specification. Use when standard reel packaging is required for automated assembly lines.

SPMWHT541MP5WAR0S4 (Cut Tape & Digi-Reel): Use when mixed packaging formats or smaller quantity requirements are needed. Highest inventory availability (500,300 pcs).

SPMWHT541MP5WARKS4 (Cut Tape): Use when cut tape format is specified for manual or semi-automated assembly. Moderate inventory availability (73,313 pcs).

SPMWHT541MP5WARMS4 (Tape & Reel): Alternative reel format. Use when primary reel option is unavailable. Lower inventory availability (19,382 pcs).

The 1°C/W difference in thermal resistance (14°C/W vs 15°C/W) between the main part and substitutes has negligible impact on thermal performance in typical operating conditions and does not affect component selection criteria.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable? A: Yes. All four parts are parametric equivalents with identical forward voltage (2.95V), test current (65mA), flux output (34lm at 65mA), efficiency (177 lm/W), CRI (80), and viewing angle (120°). They operate identically in circuit.

Q: Can I substitute SPMWHT541MP5WARSS4 with SPMWHT541MP5WAR0S4 on my PCB? A: Yes. Both use the identical 4-SMD flat lead 5630 package with 5.00mm x 3.00mm x 0.80mm dimensions. PCB footprints are directly compatible. The only difference is the supply packaging format (Tape & Reel vs Cut Tape & Digi-Reel).

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel (TR) supplies components on continuous reels for high-volume automated assembly. Cut Tape (CT) supplies components on tape segments for lower volumes or manual assembly. Digi-Reel is a hybrid format combining cut tape with reel capability. Component performance is identical regardless of supply format.

Q: Does the thermal resistance difference matter? A: The main part specifies 14°C/W while substitutes specify 15°C/W. This 1°C/W difference is within typical manufacturing tolerance and has negligible impact on thermal performance in standard operating conditions. Both ratings support identical current and temperature specifications.

Q: Are all parts ROHS3 compliant? A: Yes. All four parts are ROHS3 compliant and suitable for applications requiring environmental compliance.

Q: Which substitute should I choose if multiple are available? A: Selection depends on packaging requirements and inventory needs. SPMWHT541MP5WAR0S4 offers highest availability. SPMWHT541MP5WARSS4 and SPMWHT541MP5WARMS4 are preferred for automated reel-based assembly. SPMWHT541MP5WARKS4 is suitable for cut tape applications.
