Substitute Part Grouping Explanation

Substitute parts for the SPMWHT541ML5XAV0S5 are identified based on strict parametric alignment in the following categories:

Group 1: Direct Parametric Equivalents (LM561C Series) Parts that maintain identical electrical performance, thermal characteristics, and mechanical form factor. These substitutes operate at the same forward voltage (2.75V typical), test current (65mA), and deliver equivalent luminous flux (34 lm at 25°C, 65mA). Thermal resistance remains at 12°C/W, ensuring identical thermal behavior in circuit designs.

Group 2: Compatible Alternatives (LM561B Plus Series) Parts that share the same color temperature (3000K warm white), viewing angle (120°), package format (5630, 4-SMD flat leads), and physical dimensions, but operate at different electrical parameters. These components have higher forward voltage (2.95V typical), lower maximum current rating (180mA vs. 200mA), and different thermal resistance (15°C/W vs. 12°C/W). Substitution requires circuit design verification to accommodate voltage and current differences.

The key parameters determining substitution eligibility are:

• Color and correlated color temperature (CCT)
• Luminous flux output at specified test conditions
• Viewing angle
• Package type and physical dimensions
• Thermal resistance characteristics
• RoHS and compliance status

Engineering Selection Recommendations

SPMWHT541ML5XAVMS5 (Recommended Primary Substitute)

This part is the optimal direct substitute for SPMWHT541ML5XAV0S5. It maintains identical electrical specifications (2.75V Vf, 65mA test current, 200mA maximum), thermal resistance (12°C/W), and luminous output (34 lm). Both components are LM561C series with Active product status. The primary difference is RoHS certification level (ROHS3 vs. RoHS Compliant), which represents enhanced compliance documentation. Inventory availability is significantly higher (10,671 pcs vs. 992 pcs), making this substitute suitable for immediate replacement in production environments.

SPMWHT541MP5WAVMS5 (Compatible Alternative)

This LM561B Plus series component shares identical color temperature, viewing angle, package format, and physical dimensions. However, it operates at 2.95V forward voltage (0.20V higher) and 180mA maximum current (20mA lower) compared to the main part. Thermal resistance increases to 15°C/W. Luminous efficacy decreases from 190 lm/W to 177 lm/W. This part is suitable only when circuit design accommodates the higher forward voltage drop and lower current headroom. Product status is Active with ROHS3 compliance. Inventory is abundant (26,898 pcs).

SPMWHT541MP5WAVUS5 (Not Recommended for New Designs)

This LM561B Plus variant carries "Not For New Designs" product status, indicating Samsung has discontinued active development and support. While electrically and mechanically compatible with SPMWHT541MP5WAVMS5, this part should be avoided in new circuit designs. It is retained in this reference only for legacy system maintenance and repair applications. RoHS compliance is standard (not ROHS3).

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAVMS5 be used as a direct drop-in replacement for SPMWHT541ML5XAV0S5?

A: Yes. Both parts are LM561C series with identical forward voltage (2.75V), test current (65mA), maximum current (200mA), luminous flux (34 lm), and thermal resistance (12°C/W). The 4-SMD flat lead package, 5630 form factor, and physical dimensions (5.00 × 3.00 × 0.80 mm) are identical. No circuit modifications are required.

Q: What are the electrical differences between LM561C and LM561B Plus series?

A: The LM561B Plus series operates at 2.95V typical forward voltage compared to 2.75V for LM561C, representing a 0.20V increase. Maximum current rating is 180mA (vs. 200mA for LM561C). Thermal resistance is 15°C/W (vs. 12°C/W). Luminous efficacy is 177 lm/W (vs. 190 lm/W). Both series deliver equivalent luminous flux (34 lm) at 65mA test current and maintain 3000K color temperature with 80 CRI.

Q: Can LM561B Plus parts substitute for LM561C in existing designs?

A: Substitution requires circuit design verification. The higher forward voltage (2.95V vs. 2.75V) increases voltage drop across the LED, affecting current-limiting resistor calculations and power supply requirements. The lower maximum current rating (180mA vs. 200mA) may limit design headroom. Thermal resistance increase (15°C/W vs. 12°C/W) affects thermal management. Designs with tight voltage budgets or high current requirements may not accommodate these changes.

Q: What is the significance of ROHS3 vs. RoHS Compliant certification?

A: ROHS3 represents enhanced RoHS compliance documentation and traceability requirements introduced in later regulatory updates. Both certifications indicate the part meets RoHS substance restrictions. ROHS3 is the current standard for new component certifications. Parts with standard RoHS Compliant status remain compliant but may lack the enhanced documentation level of ROHS3-certified parts.

Q: Why is SPMWHT541MP5WAVUS5 marked "Not For New Designs"?

A: This designation indicates Samsung has transitioned this part to end-of-life status and no longer recommends it for new circuit development. The part remains available for existing inventory and legacy system support. New designs should use SPMWHT541MP5WAVMS5 (Active status) or SPMWHT541ML5XAVMS5 (LM561C series) instead.

Q: Are all substitute parts compatible with the same PCB layout and reflow profile?

A: Yes. All listed substitutes share identical package type (4-SMD, flat leads), supplier device package designation (5630), and physical dimensions (5.00 × 3.00 × 0.80 mm maximum height). PCB footprints and reflow profiles are interchangeable. Moisture sensitivity level (MSL 2A, 4 weeks) is identical across all parts.

Q: What inventory considerations apply when selecting substitutes?

A: SPMWHT541ML5XAV0S5 has 992 pcs in stock. SPMWHT541ML5XAVMS5 has 10,671 pcs available, providing significantly higher inventory buffer. SPMWHT541MP5WAVMS5 has 26,898 pcs, the highest availability. SPMWHT541MP5WAVUS5 has 11,711 pcs but carries "Not For New Designs" status. For production continuity, SPMWHT541ML5XAVMS5 offers the best balance of direct compatibility and inventory depth.
