Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MJ7WAPSS0 is determined by the following critical parameters:

• Color temperature matching: 6500K cool white specification
• Color rendering index: CRI 90 minimum
• Forward voltage: 2.95V typical
• Test current: 65mA nominal operation
• Maximum current rating: 180mA
• Viewing angle: 120° minimum
• Thermal resistance: 15°C/W
• Compliance certifications: ROHS3 Compliant, REACH Unaffected
• Mounting type: Surface Mount

The substitute part SPMWHT541MP7WAPSS0 meets all critical electrical and thermal parameters within acceptable tolerances. Both parts are manufactured by Samsung Semiconductor, Inc., operate at identical forward voltage and test current specifications, maintain equivalent thermal resistance, and share identical compliance certifications. The primary difference is the package configuration: the main part uses 2212 (5630 Metric) packaging, while the substitute uses 4-SMD Flat Leads with 5630 supplier device package designation.

Parameter Comparison

Engineering Selection Recommendations

The SPMWHT541MP7WAPSS0 is a valid substitute for the SPMWHT541MJ7WAPSS0 based on electrical and compliance equivalence. Both parts maintain identical forward voltage (2.95V), test current (65mA), maximum current rating (180mA), color temperature (6500K), CRI (90), viewing angle (120°), and thermal resistance (15°C/W). Both are ROHS3 Compliant and REACH Unaffected.

The substitute part offers the advantage of Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy designation of the main part. The luminous flux difference of 1 lm at test current (29 lm vs. 30 lm) and efficiency difference of 5 lm/W (151 lm/W vs. 156 lm/W) fall within acceptable engineering tolerances for most lighting applications.

Physical dimensions differ slightly: the substitute is 0.30 mm shorter in length (5.00 mm vs. 5.30 mm) and 0.10 mm lower in seated height (0.80 mm vs. 0.90 mm). These dimensional variations require verification against PCB layout and mechanical assembly constraints specific to your application. Package configuration differences (2212 vs. 4-SMD Flat Leads) necessitate footprint compatibility assessment.

Selection should prioritize the Active status substitute part to mitigate supply chain risk associated with Last Time Buy inventory depletion.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAPSS0 directly replace SPMWHT541MJ7WAPSS0 on existing PCBs?

A: Electrical substitution is valid; however, physical compatibility requires verification. The substitute part is 0.30 mm shorter in length and 0.10 mm lower in height. PCB footprint and mechanical clearance must be confirmed before implementation. Package configuration differs (2212 vs. 4-SMD Flat Leads), requiring footprint compatibility assessment.

Q: What is the significance of the Last Time Buy status on the main part?

A: Last Time Buy indicates discontinued production with limited remaining inventory. The SPMWHT541MJ7WAPSS0 will not be replenished once current stock is depleted. Transitioning to the Active status substitute part (SPMWHT541MP7WAPSS0) ensures long-term supply chain continuity.

Q: Are the luminous flux and efficiency differences between these parts significant?

A: The main part delivers 30 lm at 156 lm/W, while the substitute delivers 29 lm at 151 lm/W. These differences represent 3.3% and 3.2% variance respectively and fall within acceptable engineering tolerances for most lighting applications. Application-specific brightness requirements should be evaluated.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SPMWHT541MJ7WAPSS0 and SPMWHT541MP7WAPSS0 are ROHS3 Compliant and REACH Unaffected, meeting identical regulatory requirements.

Q: What are the key electrical parameters that make these parts equivalent?

A: Forward voltage (2.95V), test current (65mA), maximum current (180mA), color temperature (6500K), CRI (90), viewing angle (120°), and thermal resistance (15°C/W) are identical between both parts, establishing electrical equivalence.

Q: How do the package dimensions affect component selection?

A: The substitute part (5.00 mm × 3.00 mm, 0.80 mm height) is slightly smaller than the main part (5.30 mm × 3.00 mm, 0.90 mm height). PCB layout, solder reflow profiles, and mechanical assembly processes must accommodate these dimensional differences. Verify footprint compatibility with your design specifications.
