SPMWHT541ML5XATUS6 Equivalent & Substitute Parts

Part Overview

The SPMWHT541ML5XATUS6 is an LED lighting component from Samsung Semiconductor's LM561C series, designed for neutral white illumination at 4000K color temperature. This surface-mount LED operates at 2.75V forward voltage with a test current of 65mA, delivering 37 lumens at 25°C and achieving 207 lumens per watt efficiency. The component is housed in a 5630 package format with 4-SMD flat leads and a 120° viewing angle. With active product status and full RoHS3 compliance, this LED is suitable for general lighting applications requiring neutral white output. Identifying equivalent substitute parts becomes necessary when managing inventory constraints, ensuring supply chain continuity, or optimizing procurement across multiple manufacturing batches.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541ML5XATUS6 is determined by strict alignment across the following critical parameters:

Series and color temperature matching ensures optical and thermal performance consistency. The LM561C series designation and 4000K neutral white specification define the functional category.

Electrical parameters—forward voltage (2.75V typical), test current (65mA), and maximum current rating (200mA)—must remain identical to ensure circuit compatibility without redesign.

Photometric output, measured as flux at 25°C test conditions (37lm ±1lm range) and lumens-per-watt efficiency (207 lm/W), establishes performance equivalence.

Color rendering index (CRI 80) and viewing angle (120°) are fixed optical characteristics that cannot vary.

Mechanical compatibility requires identical package format (4-SMD, Flat Leads), supplier device package designation (5630), physical dimensions (5.00mm x 3.00mm), and maximum seated height (0.80mm).

Thermal characteristics, specifically thermal resistance of package (12°C/W), must match to maintain thermal management consistency.

Compliance certifications—RoHS3 and REACH status—must be equivalent or superior.

Parameter Comparison

Engineering Selection Recommendations

Both SPMWHT541ML5XATUS6 and SPMWHT541ML5XATMS6 are active products from Samsung Semiconductor with identical electrical, optical, mechanical, and thermal specifications. Selection between these parts should be based on inventory availability and procurement lead times. The SPMWHT541ML5XATMS6 variant maintains higher stock levels (29,791 pieces versus 979 pieces), which may provide supply chain advantages for high-volume applications. Both components meet RoHS3 compliance and REACH regulatory requirements, ensuring equivalent environmental and regulatory standing. No performance degradation or circuit redesign is required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Are SPMWHT541ML5XATUS6 and SPMWHT541ML5XATMS6 electrically interchangeable?

A: Yes. Both parts share identical forward voltage (2.75V), test current (65mA), maximum current rating (200mA), and photometric output (37lm at 65mA, 207 lm/W). No circuit modifications are necessary.

Q: Do these parts have the same physical footprint?
