SPMWHT541MD5WAWHS2 LED Equivalent & Substitute Parts

Part Overview

The SPMWHT541MD5WAWHS2 is a Samsung Semiconductor LM561B series warm white LED in 5630 surface mount package configuration. This component is classified as "Not For New Designs," indicating it has reached end-of-life status in Samsung's product portfolio. The part delivers warm white light at 2700K color temperature with a forward voltage of 2.9V at 65mA test current, suitable for general illumination applications requiring warm color rendering.

Due to its discontinued design status, identification of functionally equivalent active alternatives is necessary for ongoing production support, maintenance applications, and new design initiatives requiring similar performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MD5WAWHS2 is determined by strict alignment across the following critical parameters:

Color Temperature & Spectral Match: The substitute must operate at 2700K warm white to maintain identical color rendering in end-use applications.

Electrical Operating Point: Test current of 65mA and forward voltage within acceptable tolerance of 2.9V ensure circuit compatibility without redesign of current-limiting resistor networks.

Package & Footprint: The 5630 package designation (5.00mm x 3.00mm) with 4-SMD flat lead configuration must be preserved to ensure PCB assembly compatibility without layout modification.

Thermal Characteristics: Thermal resistance of the package must remain within acceptable range to maintain thermal management performance in the original application context.

Regulatory Compliance: RoHS compliance and MSL rating must be maintained to satisfy supply chain and manufacturing requirements.

The SPMWHT541MP5WAWMS4 qualifies as a direct substitute based on these criteria, with documented improvements in active product status and performance metrics.

Engineering Selection Recommendations

Primary Recommendation: SPMWHT541MP5WAWMS4

The SPMWHT541MP5WAWMS4 is the designated substitute for SPMWHT541MD5WAWHS2 applications. This recommendation is based on the following engineering factors:

Product Status: The substitute maintains active product status within Samsung's portfolio, ensuring long-term availability and supply chain continuity. The main part's "Not For New Designs" classification necessitates transition to an actively supported alternative.

Electrical Compatibility: Forward voltage differential of 0.05V (2.9V to 2.95V) is within standard circuit tolerance margins and does not require modification to current-limiting resistor calculations at 65mA test current. Maximum current rating increase from 150mA to 180mA provides additional design margin without affecting nominal operating conditions.

Physical Compatibility: Both components utilize identical 5630 package designation and 4-SMD configuration. The 0.60mm length increase (5.00mm to 5.60mm) requires verification against PCB layout constraints, particularly in space-constrained applications. The reduced height (0.90mm to 0.80mm) provides clearance advantage in applications with height restrictions.

Thermal Performance: The substitute's improved thermal resistance (15°C/W versus 16°C/W) enhances heat dissipation capability, supporting higher ambient temperature operation or extended component life in thermally demanding environments.

Regulatory Compliance: Both components maintain identical RoHS compliance status and MSL rating, eliminating supply chain or manufacturing process modifications.

Inventory Availability: The substitute demonstrates significantly higher inventory availability (25,996 units versus 759 units), supporting both immediate procurement needs and long-term production planning.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAWMS4 be used as a direct drop-in replacement for SPMWHT541MD5WAWHS2?

A: The substitute is functionally compatible for applications where the 0.60mm length increase does not create PCB layout conflicts. Verify that the substitute's 5.60mm length accommodates existing PCB footprint spacing. Both components share identical 5630 package designation, 4-SMD configuration, and 3.00mm width, supporting standard reflow assembly processes without modification.

Q: What is the significance of the forward voltage difference between 2.9V and 2.95V?

A: The 0.05V difference represents a 1.7% variation within standard LED manufacturing tolerance. At the 65mA test current, this voltage differential does not require modification to current-limiting resistor values in typical circuit designs. Verify that the application's power supply regulation accommodates this tolerance range.

Q: Are there any thermal management differences between these components?

A: The substitute exhibits improved thermal resistance (15°C/W versus 16°C/W), indicating superior heat dissipation from the LED junction to the package exterior. This 6% improvement supports operation at higher ambient temperatures or extended thermal cycling without exceeding maximum junction temperature limits. No thermal management modifications are required; the substitute performs equal to or better than the original part.

Q: Does the height reduction from 0.90mm to 0.80mm affect assembly or performance?

A: The 0.10mm height reduction is advantageous for applications with vertical clearance constraints. This dimension change does not affect electrical performance or reflow assembly processes. Verify that the reduced height does not create unintended clearance issues with adjacent components or conformal coating processes.

Q: What is the impact of the maximum current rating increase from 150mA to 180mA?

A: The higher maximum current rating provides additional design margin and thermal headroom. At the specified 65mA test current, both components operate identically. The increased maximum rating does not affect nominal operation and supports potential future design enhancements requiring higher current operation within the same package footprint.

Q: Are both components suitable for new product designs?

A: The main part (SPMWHT541MD5WAWHS2) carries "Not For New Designs" status and should not be selected for new development. The substitute (SPMWHT541MP5WAWMS4) maintains active product status and is appropriate for new designs requiring warm white 2700K LED performance in 5630 surface mount package configuration.

Q: What packaging and moisture handling considerations apply to both components?

A: Both components are supplied in Tape & Reel (TR) format with MSL rating 2A (4 Weeks), indicating identical moisture sensitivity and storage requirements. Standard moisture control procedures for MSL 2A components apply: maintain storage below 30°C and 60% relative humidity, or use desiccant packaging. Both components support standard reflow assembly processes without additional moisture bake-out procedures beyond industry standard practices.
