Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MJ7WATSS0 is determined by the following critical parameters:

Color and CCT matching: White, Neutral 4000K specification Electrical compatibility: Forward voltage 2.95V, test current 65mA, maximum current 180mA Optical performance: CRI 90, 120° viewing angle Thermal characteristics: 15°C/W thermal resistance Compliance: ROHS3 Compliant, REACH Unaffected Mounting and package form factor: Surface mount, 5630 metric footprint

The substitute part SPMWHT541MP7WATSS0 maintains electrical, optical, and thermal equivalence within the LM561B product family. Dimensional variations in length (5.00mm vs 5.30mm) and height (0.80mm vs 0.90mm) remain within acceptable tolerances for 5630 metric package classification. Both parts share identical forward voltage, test current, maximum current, CRI, viewing angle, thermal resistance, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The SPMWHT541MP7WATSS0 is the manufacturer-recommended substitute for the SPMWHT541MJ7WATSS0. Both components are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for electronic component deployment.

The substitute part maintains active product status, ensuring ongoing availability and supply chain continuity. The main part's Last Time Buy designation makes transition to the substitute necessary for future procurement.

Electrical parameters are identical: 2.95V forward voltage, 65mA test current, and 180mA maximum current ensure direct functional replacement in existing circuit designs without modification to current-limiting resistor values or power supply specifications.

Optical characteristics remain equivalent: both parts deliver 90 CRI and 120° viewing angle. Luminous flux at 25°C shows minor variation (29lm vs 31lm), falling within the specified tolerance ranges (26lm ~ 32lm for substitute, 29lm ~ 33lm for main part). Lumens per watt efficiency differs by 11 lm/W (151 vs 162), reflecting normal manufacturing variation within the LM561B product family.

Dimensional differences are minor: length reduction of 0.30mm (5.30mm to 5.00mm) and height reduction of 0.10mm (0.90mm to 0.80mm) remain within 5630 metric package tolerances. Thermal resistance remains constant at 15°C/W, ensuring equivalent thermal performance in PCB thermal management calculations.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WATSS0 directly replace SPMWHT541MJ7WATSS0 in existing designs?

A: Yes. Both parts share identical electrical specifications (2.95V Vf, 65mA test current, 180mA maximum current), optical properties (90 CRI, 120° viewing angle, 4000K CCT), and thermal characteristics (15°C/W). No circuit modifications are required.

Q: What is the difference in luminous flux between these parts?

A: The main part delivers 31lm at 25°C and 65mA, while the substitute delivers 29lm under identical conditions. Both values fall within acceptable tolerance ranges. The 2lm difference represents normal manufacturing variation within the LM561B product family and does not affect functional performance in standard lighting applications.

Q: Are there package compatibility concerns?

A: Both parts use 5630 metric footprint packages suitable for surface mount assembly. The substitute is slightly smaller (5.00mm x 3.00mm vs 5.30mm x 3.00mm length, 0.80mm vs 0.90mm height). These dimensional differences remain within standard 5630 package tolerances and do not affect PCB layout or reflow soldering processes.

Q: Why is the main part designated Last Time Buy?

A: Last Time Buy status indicates Samsung Semiconductor has discontinued the LM561B Plus series. The substitute SPMWHT541MP7WATSS0 from the active LM561B series provides equivalent performance and ensures continued component availability for production and new designs.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both SPMWHT541MJ7WATSS0 and SPMWHT541MP7WATSS0 are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for electronic component use in regulated markets.

Q: What is the efficiency difference between these parts?

A: The main part delivers 162 lm/W at 65mA, while the substitute delivers 151 lm/W. This 11 lm/W difference reflects normal variation within the LM561B product family and does not indicate performance degradation. Both parts meet the same optical and thermal specifications for standard applications.
