Parameter Comparison

Engineering Selection Recommendations

Both SPMWHT541MP5WAPSS4 and SPMWHT541MP5WAPKS4 are active production components from Samsung Semiconductor with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on supply availability and packaging format (Tape & Reel for both). The SPMWHT541MP5WAPKS4 offers significantly higher inventory availability (48,482 pieces versus 874 pieces), making it the preferred choice for high-volume procurement. Thermal resistance variance (14°C/W versus 15°C/W) and lumens-per-watt efficiency difference (172 lm/W versus 167 lm/W) remain within acceptable engineering tolerances for standard lighting applications. Both parts maintain identical electrical performance at rated test conditions and are mechanically interchangeable without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAPKS4 be used as a direct replacement for SPMWHT541MP5WAPSS4?

A: Yes. Both parts are parametrically identical across all critical electrical and mechanical specifications, including forward voltage, test current, flux output, viewing angle, package dimensions, and mounting type. No circuit modifications are required.

Q: What are the key differences between these two part numbers?

A: The primary differences are inventory availability and thermal resistance. SPMWHT541MP5WAPKS4 has higher stock levels and 1°C/W higher thermal resistance (15°C/W versus 14°C/W). Lumens-per-watt efficiency differs by 5 lm/W (167 versus 172), which is within normal manufacturing tolerance for this LED series.

Q: Are both parts suitable for the same PCB footprint?

A: Yes. Both components use identical 4-SMD, Flat Leads packaging (5630 supplier package) with matching dimensions of 5.00mm x 3.00mm x 0.80mm maximum height. No PCB layout changes are necessary.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both SPMWHT541MP5WAPSS4 and SPMWHT541MP5WAPKS4 are RoHS3 compliant and REACH unaffected, meeting current environmental and safety standards for electronic components.

Q: Which part should be selected for new designs?

A: Selection should prioritize supply chain availability. SPMWHT541MP5WAPKS4 is recommended for new designs due to significantly higher inventory levels, ensuring consistent procurement and reduced lead times.
