Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SPMWHT541MP5WAUNS4 are identified based on strict parametric equivalence within the LM561B Plus series. The substitution logic is determined by the following criteria:

Primary Equivalence Parameters:

• Series: LM561B Plus
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Flat Leads
• Supplier Device Package: 5630
• Physical Dimensions: 5.00 × 3.00 mm
• Height – Seated (Max): 0.80 mm
• Forward Voltage (Vf) Typical: 2.95V
• Current – Test: 65 mA
• Current – Maximum: 180 mA
• Lumens/Watt @ 65mA: 167 lm/W
• CRI: 80
• Viewing Angle: 120°
• Flux @ 25°C, 65mA: 32 lm (31–33 lm range)
• Packaging: Tape & Reel (TR)
• Product Status: Active
• Moisture Sensitivity Level: 2A (4 Weeks)

Allowable Variation Parameters:

• CCT (Correlated Color Temperature): 3000K or 3500K
• Thermal Resistance: 15°C/W or 16°C/W
• RoHS Status: RoHS Compliant or ROHS3 Compliant

Substitute parts maintain identical electrical performance, mechanical compatibility, and thermal characteristics while permitting CCT selection (warm white 3000K or 3500K) and minor thermal resistance tolerance (±1°C/W) and RoHS certification variant.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and are manufactured by Samsung Semiconductor, Inc. within the LM561B Plus series. Selection between SPMWHT541MP5WAUNS4 and substitute parts is determined by correlated color temperature requirement and RoHS certification variant:

For 3500K CCT applications: SPMWHT541MP5WAUNS4 (RoHS Compliant) or SPMWHT541MP5WAUMS4 (ROHS3 Compliant) are electrically and mechanically equivalent. SPMWHT541MP5WAUMS4 offers significantly higher inventory availability (200,400 pcs vs. 973 pcs) and ROHS3 compliance certification.

For 3000K CCT applications: SPMWHT541MP5WAV0S4 (RoHS Compliant) or SPMWHT541MP5WAVMS4 (ROHS3 Compliant) provide identical electrical performance with warmer color temperature. Both maintain equivalent thermal resistance tolerance (16°C/W vs. 15°C/W primary part).

Thermal Resistance Consideration: Substitute parts exhibit 16°C/W thermal resistance compared to 15°C/W for the primary part. This 1°C/W difference remains within acceptable tolerance for LM561B Plus series applications and does not affect electrical performance or luminous output.

RoHS Certification: Selection between RoHS Compliant and ROHS3 Compliant variants depends on regional regulatory requirements and supply chain specifications. Both certifications are valid for Active product status components.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAUMS4 be used as a direct replacement for SPMWHT541MP5WAUNS4?

A: Yes. Both parts are electrically and mechanically identical within the LM561B Plus series. They share identical forward voltage (2.95V), test current (65mA), luminous flux (32 lm @ 25°C), CCT (3500K), viewing angle (120°), and package dimensions (5.00 × 3.00 mm, 0.80 mm height). The thermal resistance difference (16°C/W vs. 15°C/W) is within acceptable tolerance. The primary distinction is RoHS certification variant (ROHS3 vs. RoHS Compliant) and significantly higher inventory availability.

Q: What is the difference between 3500K and 3000K CCT variants?

A: Correlated Color Temperature (CCT) defines the perceived warmth of the emitted light. 3500K produces neutral warm white light, while 3000K produces warmer, more amber-toned white light. Both variants maintain identical electrical parameters (voltage, current, efficiency) and mechanical compatibility. Selection depends on application color temperature specification.

Q: Are the 3000K variants (SPMWHT541MP5WAV0S4 and SPMWHT541MP5WAVMS4) compatible with designs specified for 3500K?

A: Electrical and mechanical compatibility is maintained. However, the perceived light color will differ. 3000K produces warmer light than 3500K. Substitution is valid only if the application permits CCT variation or if color temperature adjustment is acceptable.

Q: What does the thermal resistance difference (15°C/W vs. 16°C/W) mean for circuit design?

A: Thermal resistance indicates heat dissipation efficiency. The 1°C/W difference is negligible for most applications. At 65mA test current with 2.95V forward voltage (approximately 0.19W power dissipation), the temperature rise difference is less than 0.2°C. This variation does not affect component reliability or performance.

Q: Can I substitute between RoHS Compliant and ROHS3 Compliant variants?

A: Yes, both certifications are valid for Active product status. Selection depends on regional compliance requirements and supply chain specifications. ROHS3 represents an updated RoHS certification standard. Both variants meet current regulatory requirements for electronic component manufacturing.

Q: What is the significance of the 4-SMD, Flat Leads package designation?

A: This indicates a surface mount LED package with four solder leads in a flat configuration. All substitute parts use identical 5630 package geometry (5.00 × 3.00 mm footprint, 0.80 mm maximum seated height). PCB layout and reflow soldering parameters remain unchanged across all substitute parts.

Q: Are there any performance differences in luminous output between substitute parts?

A: No. All parts deliver 32 lumens (31–33 lm range) at 25°C with 65mA test current, and 167 lumens/watt efficiency. Luminous output is identical across all variants. CCT selection (3000K vs. 3500K) affects perceived light color, not total luminous flux.

Q: What is MSL 2A (4 Weeks) and how does it affect component handling?

A: Moisture Sensitivity Level (MSL) 2A indicates the component can be exposed to ambient conditions (30°C, 60% relative humidity) for up to 4 weeks before requiring dry-pack storage or baking. All substitute parts share identical MSL classification. Standard moisture control procedures apply uniformly across all variants.
