SPMWHT541MP5WAVNS4 LED LM561B Plus White 3000K Equivalent & Substitute Parts

Part Overview

The SPMWHT541MP5WAVNS4 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 standard moisture sensitivity classification (MSL 2A). Substitute parts become necessary when primary inventory is unavailable, when thermal performance requirements vary slightly, or when alternative compliance certifications are required for specific regional or contractual applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MP5WAVNS4 is determined by strict electrical and mechanical parameter matching within the LM561B Plus series. All substitute parts must maintain identical specifications across the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Color: White, Warm
• CCT: 3000K
• Luminous Flux @ 25°C, 65mA: 32 lm (31–33 lm range)
• Forward Voltage (Typ): 2.95V
• Test Current: 65mA
• Maximum Current: 180mA
• Luminous Efficacy: 167 lm/W
• CRI: 80

Mechanical Parameters (Non-Negotiable):

• Package Type: 4-SMD, Flat Leads
• Supplier Device Package: 5630
• Physical Dimensions: 5.00 × 3.00 mm footprint, 0.80 mm maximum height
• Viewing Angle: 120°
• Mounting Type: Surface Mount

Thermal & Compliance Parameters (Allowable Variance):

• Thermal Resistance: 15–16°C/W (minor variance acceptable)
• RoHS Status: RoHS Compliant or ROHS3 Compliant (both acceptable)
• MSL Rating: 2A (4 Weeks) (consistent across all variants)

The two substitute parts listed below meet all electrical and mechanical requirements while exhibiting minor thermal resistance differences and alternative RoHS certification levels, both of which remain within acceptable engineering tolerances for this product category.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SPMWHT541MP5WAVNS4, SPMWHT541MP5WAV0S4, and SPMWHT541MP5WAVMS4—are functionally equivalent for direct substitution in applications requiring warm white 3000K LED lighting at 65mA nominal operation.

Selection Criteria Based on Provided Parameters:

SPMWHT541MP5WAVNS4 (Primary Part):

• Thermal Resistance: 15°C/W (lowest thermal resistance)
• RoHS Compliance: Standard RoHS Compliant
• Inventory: 1,011 pcs
• Select when thermal performance is optimized and standard RoHS certification is required

SPMWHT541MP5WAV0S4 (Substitute 1):

• Thermal Resistance: 16°C/W (1°C/W higher than primary)
• RoHS Compliance: Standard RoHS Compliant
• Inventory: 85,670 pcs (highest availability)
• Select when maximum inventory availability is prioritized and thermal resistance variance of 1°C/W is acceptable

SPMWHT541MP5WAVMS4 (Substitute 2):

• Thermal Resistance: 16°C/W (1°C/W higher than primary)
• RoHS Compliance: ROHS3 Compliant (enhanced certification)
• Inventory: 50,200 pcs
• Select when ROHS3 certification is contractually required or when enhanced compliance documentation is necessary

All parts maintain identical electrical performance, color characteristics, and mechanical compatibility. The thermal resistance difference of 1°C/W between the primary part and substitutes is within standard engineering tolerance for this LED package category and does not affect functional performance in typical lighting applications.

Frequently Asked Questions (FAQ)

Q1: Can SPMWHT541MP5WAV0S4 be used as a direct replacement for SPMWHT541MP5WAVNS4?

A: Yes. Both parts are parametrically equivalent across all electrical specifications (color, CCT, luminous flux, forward voltage, current ratings, efficacy, and CRI). The thermal resistance difference of 1°C/W (16°C/W vs. 15°C/W) is within acceptable tolerance for this package type and does not affect circuit operation or thermal management in standard applications.

Q2: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both certifications indicate compliance with hazardous substance restrictions. ROHS3 represents an enhanced or updated compliance standard. SPMWHT541MP5WAVMS4 carries ROHS3 certification, while SPMWHT541MP5WAVNS4 and SPMWHT541MP5WAV0S4 carry standard RoHS Compliant certification. Selection depends on contractual or regional requirements; both are acceptable for equivalent functionality.

Q3: Are the physical dimensions identical across all three parts?

A: Yes. All three parts share identical dimensions: 5.00 mm length × 3.00 mm width × 0.80 mm maximum height. The 4-SMD flat-lead package and 5630 supplier device package are consistent across all variants, ensuring direct PCB footprint compatibility.

Q4: What is the significance of the 1°C/W thermal resistance difference?

A: The thermal resistance variance between 15°C/W (primary) and 16°C/W (substitutes) represents a 6.7% difference. In practical applications, this translates to approximately 1°C additional junction temperature rise under identical operating conditions. This difference is negligible for most lighting applications and does not require circuit redesign or thermal management modifications.

Q5: Can these parts be intermixed in the same production batch?

A: Yes, provided the application does not impose strict thermal performance specifications or specific RoHS certification requirements. All three parts are electrically and mechanically interchangeable. However, if thermal performance or compliance documentation must be uniform across a production run, parts should be sourced from a single variant to maintain consistency in technical records.

Q6: What does MSL 2A (4 Weeks) mean for handling and storage?

A: MSL (Moisture Sensitivity Level) 2A indicates the component can be exposed to ambient conditions (up to 30°C, 85% relative humidity) for a maximum of 4 weeks before reflow soldering. After this period, the component must be baked according to IPC standards before assembly. This specification is identical across all three parts.

Q7: Are there any application restrictions based on the 120° viewing angle?

A: No. The 120° viewing angle is consistent across all three parts and is suitable for general lighting applications. This specification does not vary between the main part and substitutes, so viewing angle performance remains unchanged regardless of which variant is selected.

Q8: How should I select between these parts if all are available?

A: Selection should be based on: (1) inventory availability if lead time is critical; (2) thermal performance requirements if the application operates in high-temperature environments; (3) compliance certification if contractual or regional standards mandate ROHS3 certification. For standard applications with no specific constraints, SPMWHT541MP5WAV0S4 offers the highest inventory availability with equivalent performance.
