SPMWHT541MD5WAPKS2 LED Equivalent & Substitute Parts

Part Overview

The SPMWHT541MD5WAPKS2 is a Samsung Semiconductor LM561B series cool white LED (6500K) designed for surface mount lighting applications. This component features a 5630 package format with 4-SMD flat lead exposed pad configuration, delivering 29 lumens at 65mA forward current with a 120° viewing angle.

The SPMWHT541MD5WAPKS2 carries a "Not For New Designs" product status, indicating Samsung has transitioned this component to end-of-life. Identifying equivalent substitute parts is necessary for ongoing production support, maintenance applications, and design continuity where this LED specification remains functionally appropriate.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MD5WAPKS2 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Color and correlated color temperature (CCT) must match: White, Cool 6500K
• Forward voltage (Vf) must remain at 2.95V typical to ensure circuit compatibility
• Test current specification of 65mA must be supported
• Viewing angle of 120° must be maintained for optical performance

Mechanical & Package Compatibility Requirements:

• Package format must be 5630 (4-SMD) to ensure PCB footprint compatibility
• Surface mount mounting type is required
• Physical dimensions (5.00mm × 3.00mm) must be identical
• Height seated maximum of 0.90mm or less ensures assembly clearance

Regulatory & Quality Requirements:

• RoHS compliance is mandatory
• MSL rating of 2A or better is required
• Base product number SPMWHT541 indicates the same LED platform

The SPMWHT541MP7WAP0S0 qualifies as a direct substitute based on matching all electrical, mechanical, and regulatory parameters within the specified tolerances.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SPMWHT541MP7WAP0S0

The SPMWHT541MP7WAP0S0 is the qualified substitute for SPMWHT541MD5WAPKS2 applications. Both components share identical electrical specifications (2.95V forward voltage, 65mA test current, 6500K color temperature, 120° viewing angle) and are mechanically compatible within the 5630 package footprint.

The substitute part offers the following advantages:

• Active Product Status: SPMWHT541MP7WAP0S0 maintains active production status, ensuring long-term availability and supply chain continuity.
• Enhanced Color Rendering: CRI rating of 90 (versus 80 on the main part) provides superior color accuracy for applications requiring higher fidelity.
• Improved Thermal Performance: Thermal resistance of 15°C/W (versus 16°C/W) and lower seated height of 0.80mm (versus 0.90mm) support better thermal management and assembly density.
• Higher Current Rating: Maximum current of 180mA (versus 150mA) provides additional operational headroom.
• Regulatory Compliance: Both parts maintain identical RoHS compliance and MSL ratings.

The luminous flux specification of the substitute (27lm, range 24–30lm) overlaps with the main part specification (29lm, range 28–30lm) within acceptable tolerance bands for lighting applications.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAP0S0 be used as a direct replacement for SPMWHT541MD5WAPKS2 without circuit modifications?

A: Yes. Both parts operate at identical forward voltage (2.95V) and test current (65mA), with matching 6500K color temperature and 120° viewing angle. No circuit redesign is required for electrical compatibility. PCB footprints are compatible within the 5630 package format.

Q: What is the difference between "Flat Lead Exposed Pad" and "Flat Leads" package designations?

A: Both designations refer to surface mount 4-SMD configurations within the 5630 package. The functional and electrical performance is equivalent for standard lighting applications. The lead configuration difference does not affect substitution eligibility.

Q: Why does the substitute part have a lower luminous flux specification (27lm vs. 29lm)?

A: The luminous flux specifications include tolerance ranges. The main part specifies 29lm (28–30lm range), while the substitute specifies 27lm (24–30lm range). Both parts operate within overlapping tolerance bands at the 65mA test current. The substitute's higher CRI rating (90 vs. 80) may offset the flux difference in color-critical applications.

Q: Is the substitute part suitable for new design applications?

A: Yes. The SPMWHT541MP7WAP0S0 carries "Active" product status, making it appropriate for new designs. The original part (SPMWHT541MD5WAPKS2) is marked "Not For New Designs," which is the primary reason for identifying this substitute.

Q: What is the impact of the 1°C/W thermal resistance improvement in the substitute?

A: The substitute's thermal resistance of 15°C/W (versus 16°C/W) represents a 6% improvement in heat dissipation efficiency. This provides marginal benefit in high-density LED arrays or applications with elevated ambient temperatures, but does not significantly alter thermal design requirements for standard applications.

Q: Are there any moisture sensitivity or storage differences between the two parts?

A: Both parts carry identical MSL (Moisture Sensitivity Level) ratings of 2A with 4-week shelf life. Storage and handling procedures are identical.

Q: Can the substitute part be used in existing inventory management systems without part number updates?

A: No. The SPMWHT541MP7WAP0S0 is a distinct part number and must be tracked separately in inventory systems. However, it can be designated as an approved substitute in component specification documents and procurement systems.
