Substitute Part Grouping Explanation

Substitution of the SPMWHT541MP5WAP0S4 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Series: LM561B Plus
• Color and CCT: White, Cool 6500K
• Flux output: 33 lm (32–34 lm range) at 25°C and 65mA test current
• Forward voltage: 2.95V typical
• Test current: 65mA
• Maximum current: 180mA
• Viewing angle: 120°
• Package type: 4-SMD, Flat Leads (5630 form factor)
• Mounting: Surface Mount
• Physical dimensions: 5.00 × 3.00 × 0.80 mm
• CRI: 80
• Thermal resistance: 15°C/W
• MSL rating: 2A (4 Weeks)

The substitute part SPMWHT541MP5WAPKS4 meets all mandatory matching parameters and is therefore classified as a parametric equivalent. Minor variations in lumens-per-watt efficiency (167 lm/W versus 172 lm/W) fall within acceptable manufacturing tolerance ranges and do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

Both the SPMWHT541MP5WAP0S4 and SPMWHT541MP5WAPKS4 are active production parts from Samsung Semiconductor and are suitable for direct substitution in applications requiring LM561B Plus cool white 6500K LEDs.

Compliance Considerations:

The SPMWHT541MP5WAP0S4 carries RoHS Compliant certification, while the substitute SPMWHT541MP5WAPKS4 carries ROHS3 Compliant certification. Both certifications satisfy RoHS requirements; ROHS3 represents a more recent compliance standard. Selection between these parts should be based on procurement availability, inventory levels, and specific regulatory requirements of the end application.

Performance Equivalence:

The efficiency difference of 5 lm/W (172 lm/W versus 167 lm/W) represents a 2.9% variance and falls within normal manufacturing tolerance for LED components. Both parts deliver identical luminous flux (33 lm) at the specified test current and operating conditions.

Inventory and Availability:

The SPMWHT541MP5WAPKS4 maintains significantly higher inventory availability (48,482 pieces) compared to the SPMWHT541MP5WAP0S4 (830 pieces), making it the preferred choice for high-volume procurement and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAPKS4 be used as a direct replacement for SPMWHT541MP5WAP0S4?

A: Yes. Both parts are parametric equivalents with identical electrical characteristics, optical properties, physical dimensions, and package specifications. They are directly interchangeable in circuit designs and PCB layouts.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both certifications indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current version of the standard. Both are acceptable for applications requiring RoHS compliance.

Q: Are there differences in thermal performance between these parts?

A: No. Both parts have identical thermal resistance ratings of 15°C/W and identical physical dimensions, ensuring equivalent thermal behavior in circuit applications.

Q: Why is the lumens-per-watt efficiency different between the two parts?

A: The 5 lm/W difference (172 versus 167 lm/W) represents normal manufacturing variation within the LM561B Plus product line. Both parts deliver the same 33 lm luminous flux at the specified test conditions, confirming functional equivalence.

Q: Are the parts compatible with the same PCB footprint?

A: Yes. Both parts use identical 4-SMD flat lead packages in 5630 form factor with matching dimensions of 5.00 × 3.00 × 0.80 mm. No PCB redesign is required for substitution.

Q: What is the MSL rating and why does it matter?

A: Both parts carry MSL 2A (4 Weeks) rating, indicating moisture sensitivity level. This specifies that components must be used within 4 weeks of package opening under controlled humidity conditions. Handling procedures are identical for both parts.

Q: Can these parts be used at currents other than 65mA?

A: Both parts are rated for operation up to 180mA maximum current. However, optical and thermal characteristics are specified at the 65mA test current. Operation at different currents will produce different luminous output and thermal behavior.

Q: What is the viewing angle specification and how does it affect application design?

A: Both parts have a 120° viewing angle, indicating the half-angle at which luminous intensity drops to 50% of peak. This specification is identical for both parts and affects light distribution in the application.
