SPMWHT541MJ7WAQMS0 Equivalent & Substitute Parts

Part Overview

The SPMWHT541MJ7WAQMS0 is an LED Lighting component from Samsung Semiconductor's LM561B Plus series, featuring cool white 5700K color temperature. This part is designated as Last Time Buy, indicating discontinued production status. The component operates at 2.95V forward voltage with 65mA test current, delivering 31lm at 25°C and 162 lm/W efficiency. Surface mount packaging in 2212 (5630 Metric) format with 120° viewing angle and 90 CRI makes this suitable for general illumination applications. Locating equivalent substitute parts is necessary due to the Last Time Buy status and limited remaining inventory.

Parameter Comparison

Engineering Selection Recommendations

The SPMWHT541MP7WAQMS0 serves as the primary substitute for the SPMWHT541MJ7WAQMS0. The substitute part maintains Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy designation of the original part.

Both components share identical electrical specifications (2.95V forward voltage, 65mA test current, 180mA maximum current) and optical characteristics (120° viewing angle, 90 CRI, 5700K color temperature). Thermal resistance remains constant at 15°C/W.

The substitute exhibits slightly lower luminous flux (28lm versus 31lm at 25°C) and efficiency (146 lm/W versus 162 lm/W), representing a 10% reduction in light output. Package dimensions differ slightly, with the substitute measuring 5.00mm x 3.00mm versus 5.30mm x 3.00mm for the original, and seated height of 0.80mm versus 0.90mm.

Both parts maintain equivalent RoHS compliance and EAR99 export classification. The substitute includes MSL 2A (4 Weeks) moisture sensitivity specification.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAQMS0 directly replace SPMWHT541MJ7WAQMS0 in existing designs?

A: Direct replacement is feasible for most applications due to matching electrical specifications and optical characteristics. The 10% reduction in luminous flux and efficiency should be evaluated against application light output requirements. Slight dimensional differences (0.30mm length reduction, 0.10mm height reduction) require verification of PCB layout and thermal management clearances.

Q: What are the key differences between these two parts?

A: The primary differences are product status (Active versus Last Time Buy), luminous flux output (28lm versus 31lm), efficiency (146 lm/W versus 162 lm/W), package configuration (4-SMD Flat Leads versus 2212), and physical dimensions. Electrical and optical specifications remain aligned.

Q: Are there compliance or certification differences?

A: Both parts carry EAR99 export classification and equivalent HTSUS codes. The original part specifies ROHS3 Compliant with REACH Unaffected status. The substitute specifies RoHS Compliant with MSL 2A moisture sensitivity. Verify specific compliance requirements for your application.

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

A: Last Time Buy indicates the SPMWHT541MJ7WAQMS0 is discontinued with limited remaining inventory (916 Pcs). The Active status of SPMWHT541MP7WAQMS0 ensures long-term availability and supply continuity.

Q: How do package differences affect PCB design?

A: The substitute uses 4-SMD Flat Leads configuration versus 2212 format. Dimensional reductions (length 5.00mm versus 5.30mm, height 0.80mm versus 0.90mm) may allow tighter component spacing. Verify footprint compatibility with existing PCB designs and reflow profile requirements.

Q: Are thermal characteristics equivalent?

A: Both parts maintain 15°C/W thermal resistance. Verify thermal management adequacy given the 10% reduction in light output, which may affect heat dissipation requirements in your specific application.
