SPMWHT541MP5WARSS5 LED Equivalent & Substitute Parts

Part Overview

The SPMWHT541MP5WARSS5 is an active Samsung Semiconductor LM561B Plus white LED designed for surface mount applications. This 5630 package component operates at 5000K color temperature with a forward voltage of 2.95V and test current of 65mA, delivering 36 lumens at 188 lm/W efficiency. The component is ROHS3 compliant and currently in active production status. Substitute parts are identified to address inventory availability, lead time requirements, or specific packaging and compliance variations while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MP5WARSS5 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Color (White, Cool), CCT (5000K), forward voltage (2.95V typical), test current (65mA), maximum current (180mA), flux output (36 lm at 25°C), lumens per watt (188 lm/W), and CRI (80).

Mechanical Parameters: Package type (4-SMD, Flat Leads), supplier device package (5630), dimensions (5.00mm L × 3.00mm W × 0.80mm H maximum seated height), and surface mount mounting type.

Compliance Parameters: ROHS3 compliance and REACH unaffected status.

The identified substitute parts SPMWHT541MP5WAR0S5 and SPMWHT541MP5WARMS5 meet all electrical and mechanical equivalence criteria. Variations in thermal resistance (14°C/W vs. 15°C/W) and moisture sensitivity level (MSL 2A for substitutes) do not affect functional substitution within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and are manufactured by Samsung Semiconductor, Inc. The SPMWHT541MP5WARSS5 and SPMWHT541MP5WARMS5 are both ROHS3 compliant. The SPMWHT541MP5WAR0S5 is ROHS3 compliant with higher current inventory availability (17,892 units). Both substitute parts include moisture sensitivity level (MSL) 2A rating with 4-week shelf life specification.

Thermal resistance differs marginally between the main part (14°C/W) and substitutes (15°C/W), representing a 1°C/W variation that does not alter functional equivalence within standard operating conditions. Selection between substitute parts should be based on inventory availability, lead time requirements, and specific moisture handling protocols required by the application environment.

Frequently Asked Questions (FAQ)

Q: Are SPMWHT541MP5WAR0S5 and SPMWHT541MP5WARMS5 direct electrical equivalents to SPMWHT541MP5WARSS5?

A: Yes. All three parts share identical electrical specifications: 5000K color temperature, 2.95V forward voltage, 65mA test current, 36 lumens output, 188 lm/W efficiency, 80 CRI, and 120° viewing angle.

Q: Do the substitute parts fit the same PCB footprint?

A: Yes. All parts use the 4-SMD flat leads package in 5630 form factor with identical dimensions of 5.00mm length × 3.00mm width × 0.80mm maximum seated height.

Q: What is the significance of the thermal resistance difference (14°C/W vs. 15°C/W)?

A: The 1°C/W variation is within normal manufacturing tolerance for this package type and does not affect thermal performance in standard applications. Selection should be based on specific thermal design requirements if operating near maximum current limits.

Q: Why do substitute parts include MSL 2A moisture sensitivity rating?

A: MSL 2A indicates the component requires controlled storage conditions (4 weeks at 30°C/60% RH maximum). This is standard for surface mount LEDs and does not affect electrical or mechanical compatibility.

Q: Can I use SPMWHT541MP5WAR0S5 if my design specifies SPMWHT541MP5WARSS5?

A: Yes, provided your application does not have specific requirements tied to the original part number's unique identifiers. Electrical, mechanical, and compliance parameters are equivalent.
