Substitute Part Grouping Explanation

Substitution of SPMWHT541ML5XAWKS0 with SPMWHT541ML5XAWMS0 is based on strict equivalence of the following critical parameters:

Identical Parameters:

• Series designation (LM561C)
• Color specification (White, Warm)
• Correlated color temperature (2700K)
• Luminous flux at test conditions (32 lm, 30–34 lm range)
• Test current (65mA)
• Maximum current rating (180mA)
• Viewing angle (120°)
• Package type (4-SMD, Flat Leads, 5630)
• Physical dimensions (5.00mm × 3.00mm)
• Seated height (0.80mm)
• Thermal resistance (12°C/W)
• Color Rendering Index (80)
• Mounting type (Surface Mount)
• Moisture Sensitivity Level (2A, 4 Weeks)
• Regulatory classification (ECCN: EAR99, HTSUS: 8541.41.0000)

Allowable Variation:

• Forward voltage (Vf): 2.75V (main part) versus 2.8V (substitute) represents a 0.05V difference within acceptable operating tolerance for this LED category
• Lumens per watt efficiency: 180 lm/W (main) versus 176 lm/W (substitute) represents a 2.2% variance within normal manufacturing tolerance
• RoHS compliance status: RoHS Compliant (main) versus ROHS3 Compliant (substitute) both satisfy regulatory requirements

Both parts share the same base product number (SPMWHT541) and are manufactured by Samsung Semiconductor, Inc., confirming design equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both SPMWHT541ML5XAWKS0 and SPMWHT541ML5XAWMS0 are active products manufactured by Samsung Semiconductor, Inc., and satisfy regulatory compliance requirements. Selection between these parts is determined by availability and application-specific requirements:

SPMWHT541ML5XAWKS0 is selected when:

• Inventory availability is confirmed (762 pcs in stock)
• Forward voltage specification of 2.75V is required
• Efficiency target of 180 lm/W is specified
• RoHS Compliant certification is required

SPMWHT541ML5XAWMS0 is selected when:

• Higher inventory availability is required (31,957 pcs in stock)
• Forward voltage tolerance of 2.8V is acceptable
• Efficiency variance of 176 lm/W is acceptable
• ROHS3 Compliant certification is required

Both parts are electrically and mechanically interchangeable within the specified parameter tolerances. The forward voltage difference of 0.05V and efficiency variance of 2.2% fall within normal manufacturing tolerance for LED components in this category and do not affect functional compatibility in standard applications.

Frequently Asked Questions (FAQ)

Q: Are SPMWHT541ML5XAWKS0 and SPMWHT541ML5XAWMS0 pin-compatible?

A: Yes. Both parts use identical 4-SMD, Flat Leads packaging (5630 supplier device package) with matching physical dimensions (5.00mm × 3.00mm) and seated height (0.80mm). PCB footprints and solder pad layouts are identical.

Q: What is the significance of the forward voltage difference (2.75V vs. 2.8V)?

A: The 0.05V difference represents normal manufacturing tolerance for LED components. Both values fall within acceptable operating range for standard LED driver circuits. Circuit designs accommodating typical LED forward voltage ranges of 2.5V to 3.0V will operate both parts without modification.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Both parts share identical electrical characteristics for luminous flux (32 lm), test current (65mA), maximum current (180mA), color temperature (2700K), viewing angle (120°), and thermal properties (12°C/W). The minor variations in forward voltage and efficiency do not require design changes.

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 revision of the directive. Both parts meet environmental and safety standards for electronic components.

Q: Which part should be selected for new designs?

A: SPMWHT541ML5XAWMS0 is recommended for new designs due to significantly higher inventory availability (31,957 pcs versus 762 pcs), ensuring supply chain continuity. The electrical and mechanical characteristics are equivalent to SPMWHT541ML5XAWKS0.

Q: Are there any thermal management differences between these parts?

A: No. Both parts have identical thermal resistance of 12°C/W, indicating equivalent heat dissipation characteristics. Thermal design considerations are identical for both components.

Q: What is the moisture sensitivity requirement for storage and handling?

A: Both parts are classified as MSL 2A (Moisture Sensitivity Level 2A), requiring storage in controlled humidity environments and limiting floor life to 4 weeks after bag opening. Standard moisture-barrier packaging and desiccant storage are required.
