Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MJ7WARSS0 is determined by the following critical parameters:

• Color and CCT: White, Cool 5000K
• Electrical characteristics: 2.95V forward voltage, 65mA test current, 180mA maximum current
• Optical output: Minimum 30 lumens at 25°C test conditions
• CRI: 90 or higher
• Viewing angle: 120°
• Mounting: Surface mount configuration
• Compliance: ROHS3 Compliant, REACH Unaffected

The substitute part SPMWHT541MP7WARSS0 meets these criteria while operating within the same electrical and optical performance envelope. Both parts are manufactured by Samsung Semiconductor and maintain compatibility with the specified electrical and thermal parameters.

Parameter Comparison

Engineering Selection Recommendations

The SPMWHT541MP7WARSS0 is suitable as a substitute for the SPMWHT541MJ7WARSS0 based on the following factors:

Both parts maintain identical electrical specifications (2.95V forward voltage, 65mA test current, 180mA maximum current) and optical characteristics (5000K CCT, 90 CRI, 120° viewing angle). Both are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.

The primary difference is product status: the main part is Last Time Buy while the substitute is Active, ensuring continued availability. The substitute operates within the specified luminous flux range (30lm minimum specification met) and maintains equivalent thermal resistance (15°C/W).

Physical dimensions show minor variation: the substitute is slightly smaller in length (5.00mm vs 5.30mm) and height (0.80mm vs 0.90mm), which may require PCB layout verification for space-constrained applications. Both parts use surface mount technology with compatible lead configurations for standard reflow soldering processes.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WARSS0 be used as a direct replacement for SPMWHT541MJ7WARSS0?

A: Yes, within the specified electrical and optical parameters. Both parts operate at 2.95V forward voltage with 65mA test current and deliver equivalent luminous output at 5000K CCT with 90 CRI. Physical dimensions differ slightly; PCB layout compatibility should be confirmed.

Q: What is the difference between the 2212 and 4-SMD, Flat Leads packages?

A: Both are 5630 Metric footprint variants. The main part uses 2212 designation (0.209" L x 0.118" W, 0.90mm height), while the substitute uses 4-SMD, Flat Leads designation (0.197" L x 0.118" W, 0.80mm height). The substitute is slightly more compact. Standard reflow soldering processes apply to both.

Q: Why is the main part marked as Last Time Buy?

A: Last Time Buy status indicates Samsung Semiconductor has discontinued production of the SPMWHT541MJ7WARSS0. The substitute SPMWHT541MP7WARSS0 remains in active production, ensuring long-term component availability.

Q: Are there differences in luminous efficiency between these parts?

A: The main part delivers 167 lm/W while the substitute delivers 156 lm/W at test conditions. Both meet the minimum 30 lumen specification at 65mA. The efficiency difference reflects manufacturing variations within the LM561B product line.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components.
