SPMWHT541MP5WAUSS4 Equivalent & Substitute Parts

Part Overview

The SPMWHT541MP5WAUSS4 is an LED lighting component from Samsung Semiconductor's LM561B Plus series, designed for warm white illumination applications. This surface mount LED operates at 3500K color temperature with a forward voltage of 2.95V and test current of 65mA, delivering 32 lumens at 25°C. The component is actively produced and maintains full RoHS3 compliance, making it suitable for current production environments and new designs requiring warm white LED solutions in compact 5630 package form factors.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across the specified parameter set.

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MP5WAUSS4 is determined by strict equivalence across the following critical parameters:

• Series and Product Line: Both parts must belong to the LM561B Plus series
• Color and CCT: Warm white at 3500K
• Electrical Performance: Forward voltage of 2.95V (typical), test current of 65mA, maximum current of 180mA
• Optical Output: 32 lumens at 25°C and 65mA test current, 167 lm/W efficiency, 80 CRI
• Mechanical Compatibility: 4-SMD flat leads package, 5630 supplier device package, 5.00mm × 3.00mm dimensions, 0.80mm maximum seated height
• Regulatory Compliance: RoHS3 compliant, EAR99 ECCN classification
• Product Status: Active production status

The SPMWHT541MP5WAUMS4 meets all substitution criteria as a parametric equivalent within the LM561B Plus warm white LED family.

Parameter Comparison

Engineering Selection Recommendations

Both the SPMWHT541MP5WAUSS4 and SPMWHT541MP5WAUMS4 are active production components from Samsung Semiconductor with full RoHS3 compliance and EAR99 ECCN classification. Selection between these parts should be based on availability and supply chain requirements rather than technical performance differences, as all specified electrical, optical, and mechanical parameters are equivalent.

The SPMWHT541MP5WAUMS4 offers significantly higher inventory availability (200,400 pieces versus 769 pieces), making it the preferred choice for volume production and long-term supply security. Both parts are suitable for direct substitution in existing designs without circuit modification or thermal management redesign, given the minor thermal resistance variance (14°C/W versus 16°C/W) remains within acceptable operating margins for typical LED lighting applications.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAUMS4 replace SPMWHT541MP5WAUSS4 in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical performance (2.95V forward voltage, 65mA test current, 32 lumens), optical characteristics (3500K, 80 CRI, 120° viewing angle), and mechanical compatibility (5630 package, 5.00mm × 3.00mm, 0.80mm height). Direct substitution requires no circuit changes.

Q: What is the difference between these two part numbers?

A: The parts differ only in thermal resistance specification (14°C/W versus 16°C/W) and packaging designation suffix (USS4 versus UMS4). All functional and performance parameters are identical. The thermal resistance difference is negligible for standard LED lighting applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both SPMWHT541MP5WAUSS4 and SPMWHT541MP5WAUMS4 are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the 5630 package designation?

A: The 5630 designation refers to the supplier device package format, indicating a 5.00mm × 3.00mm surface mount LED with 4-SMD flat leads and 0.80mm maximum seated height. This is a standard form factor for high-efficiency warm white LEDs.

Q: Can these parts be used interchangeably in production?

A: Yes. Both parts maintain identical performance specifications and mechanical compatibility. Production line qualification for one part automatically qualifies the other for direct substitution without process modification.
