SPMWHT541MP5WAVKS4 LED LM561B Plus White 3000K Equivalent & Substitute Parts

Part Overview

The SPMWHT541MP5WAVKS4 is an LED lighting component from Samsung Semiconductor's LM561B Plus series, engineered for warm white illumination at 3000K color temperature. This surface-mount LED operates at 2.95V forward voltage with a nominal test current of 65mA, delivering 32 lumens at 167 lm/W efficiency. The component is packaged in a 5630 4-SMD flat-lead configuration with a 120° viewing angle, suitable for general lighting applications requiring consistent color rendering (CRI 80).

The product maintains Active status with full RoHS compliance and MSL 2A moisture sensitivity rating. Equivalent substitute parts are available within the same LM561B Plus series, offering identical electrical and optical performance characteristics while providing alternative sourcing options for supply chain continuity.

Substitute Part Grouping Explanation

Substitution within the SPMWHT541MP5WAV series is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Color temperature: 3000K (warm white)
• Forward voltage: 2.95V typical
• Test current: 65mA nominal
• Maximum current rating: 180mA
• Luminous flux: 32 lm (31–33 lm range)
• Luminous efficacy: 167 lm/W
• CRI: 80

Mechanical & Package Equivalence Criteria:

• Package configuration: 4-SMD, flat leads
• Supplier device package: 5630
• Physical dimensions: 5.00mm L × 3.00mm W
• Maximum seated height: 0.80mm
• Mounting type: Surface mount

Compliance & Environmental Criteria:

• RoHS compliance status (RoHS or ROHS3)
• MSL rating: 2A (4 Weeks)
• Product status: Active

All substitute parts listed maintain identical electrical performance, optical output, and mechanical compatibility with the main part number SPMWHT541MP5WAVKS4. Variations in thermal resistance (15°C/W vs. 16°C/W) and RoHS certification level do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—SPMWHT541MP5WAVKS4, SPMWHT541MP5WAV0S4, and SPMWHT541MP5WAVMS4—are functionally equivalent for direct substitution in applications requiring LM561B Plus warm white 3000K LEDs with 4-SMD 5630 packaging.

Selection Basis:

1. Electrical & Optical Performance: All parts deliver identical electrical characteristics (2.95V, 65mA nominal), optical output (32 lm), and color rendering (3000K, CRI 80). Thermal resistance variation (15°C/W vs. 16°C/W) is within acceptable engineering tolerance for most thermal management designs.

2. Compliance Status: SPMWHT541MP5WAVKS4 and SPMWHT541MP5WAV0S4 carry RoHS Compliant certification. SPMWHT541MP5WAVMS4 carries ROHS3 Compliant certification. Both certifications satisfy RoHS directive requirements; ROHS3 represents the current regulatory standard. Selection depends on customer compliance documentation requirements.

3. Availability & Supply Chain: Part selection may be driven by inventory levels and lead times. SPMWHT541MP5WAV0S4 maintains the highest inventory (85,670 pcs), followed by SPMWHT541MP5WAVMS4 (50,200 pcs) and SPMWHT541MP5WAVKS4 (795 pcs).

4. Mechanical Compatibility: All parts share identical package dimensions, mounting type, and PCB footprint. No design modifications are required for substitution.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAV0S4 replace SPMWHT541MP5WAVKS4 in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical performance, optical output, color temperature, and mechanical package. No circuit modifications or PCB redesign is required.

Q: What is the significance of the thermal resistance difference (15°C/W vs. 16°C/W)?

A: The 1°C/W difference represents a minor variation in package thermal performance. For most general lighting applications operating at 65mA nominal current, this difference does not impact thermal management. Applications with extreme thermal constraints should evaluate junction temperature rise using the specific thermal resistance value.

Q: Are all three parts suitable for high-current operation at 180mA maximum?

A: All three parts share the same maximum current rating of 180mA. However, operation at maximum current generates higher junction temperatures. Thermal resistance values should be considered when designing for sustained operation above nominal 65mA current levels.

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

A: Both certifications indicate compliance with RoHS (Restriction of Hazardous Substances) directives. ROHS3 represents the current EU RoHS Directive 2011/65/EU as amended. RoHS Compliant typically references earlier directive versions. Both are acceptable for most applications; selection depends on customer documentation requirements and regional regulations.

Q: Can these parts be used interchangeably in production without design changes?

A: Yes. All three parts are direct substitutes with identical package footprints (5630 4-SMD), lead configurations (flat leads), and mounting requirements (surface mount). No PCB layout modifications are necessary.

Q: What does MSL 2A (4 Weeks) mean for handling and storage?

A: MSL 2A indicates Moisture Sensitivity Level 2A. The component can be stored in a dry environment for up to 4 weeks after packaging. After 4 weeks, the component must be baked at 125°C for 24 hours before soldering to prevent moisture-induced defects during reflow.

Q: Are there any optical performance differences between the three part numbers?

A: No. All three parts deliver identical luminous flux (32 lm), color temperature (3000K), CRI (80), and viewing angle (120°). Optical performance is equivalent across all substitute parts.
