SPMWHT541MP7WATKS0 Equivalent & Substitute Parts

Part Overview

The SPMWHT541MP7WATKS0 is an LED lighting component from Samsung Semiconductor's LM561B Plus series. This surface-mount LED operates at neutral white 4000K color temperature and delivers 27 lumens at 65mA test current with a color rendering index of 90. The component is classified as Active product status and is RoHS Compliant, making it suitable for current production applications requiring white LED illumination in compact form factors.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and compliance certifications are maintained across the component family. The SPMWHT541MP7WATKS0 has limited inventory availability (1039 pieces), which may necessitate identification of alternative sources within the same product series.

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MP7WATKS0 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Color temperature: 4000K (Neutral White)
• Luminous flux range: 24lm to 30lm at 65mA test current
• Forward voltage: 2.95V typical
• Test current: 65mA
• Maximum current rating: 180mA
• Lumens per watt efficiency: 141 lm/W
• Color rendering index: 90

Mechanical Equivalence Criteria:

• Package type: 4-SMD, Flat Leads (5630 supplier package)
• Dimensions: 5.00mm x 3.00mm x 0.80mm maximum height
• Mounting type: Surface Mount
• Viewing angle: 120°
• Thermal resistance: 15°C/W

Compliance Equivalence Criteria:

• RoHS compliance status
• Moisture sensitivity level: 2A (4 Weeks)
• Product status: Active

Parts meeting all three equivalence categories are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The SPMWHT541MP7WATMS0 is a direct parametric equivalent to the SPMWHT541MP7WATKS0. Both components are manufactured by Samsung Semiconductor and belong to the LM561B Plus series with identical electrical, optical, and mechanical specifications.

Selection Basis:
