Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Optical Compatibility:

• Color temperature: 6500K (cool white)
• Luminous flux: 35 lm at 25°C, 65mA test current
• Color Rendering Index: 80
• Viewing angle: 120°

Electrical Compatibility:

• Forward voltage: 2.95V (LM561B Plus series) or 2.75V (LM561C series)
• Test current: 65mA
• Maximum current rating: 180mA (LM561B Plus) or 200mA (LM561C)

Mechanical Compatibility:

• Package type: 4-SMD, Flat Leads
• Supplier package designation: 5630
• Physical dimensions: 5.00mm × 3.00mm × 0.80mm maximum height
• Mounting type: Surface Mount

Compliance & Environmental:

• RoHS compliance status
• Moisture Sensitivity Level: 2A (4 Weeks)
• ECCN: EAR99
• HTSUS: 8541.41.0000

Substitute parts maintain identical optical output, mechanical form factor, and environmental specifications. Variations in forward voltage and thermal resistance reflect series-level differences (LM561B Plus versus LM561C) and packaging options (Tape & Reel variants).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Series - LM561B Plus):

Parts SPMWHT541MP5WAP0S5, SPMWHT541MP5WAPKS5, SPMWHT541MP5WAPMS5, and SPMWHT541MP5WAPSS5 are direct electrical and optical equivalents to the obsolete SPMWHT541MP5WAPNS5. All maintain identical forward voltage (2.95V), luminous flux (35 lm), and thermal resistance (15°C/W). These parts differ only in packaging format (Tape & Reel versus bulk) and are available in active production status. Selection among these four variants depends on procurement packaging requirements.

For Enhanced Performance (LM561C Series):

Parts SPMWHT541ML5XAP0S5, SPMWHT541ML5XAPKS5, and SPMWHT541ML5XAPMS5 represent the LM561C series alternative. While maintaining identical optical output (35 lm, 6500K, 80 CRI), these parts offer:

• Lower forward voltage: 2.75V versus 2.95V
• Higher luminous efficacy: 196 lm/W versus 183 lm/W
• Improved thermal performance: 12°C/W versus 15°C/W
• Higher maximum current rating: 200mA versus 180mA

LM561C substitution is appropriate for applications where reduced power dissipation or enhanced thermal headroom is beneficial. All three LM561C variants are electrically and mechanically interchangeable.

Compliance Status:

All substitute parts maintain RoHS compliance and identical moisture sensitivity ratings (MSL 2A, 4 Weeks). SPMWHT541MP5WAPSS5 carries ROHS3 and REACH Unaffected certifications.

Frequently Asked Questions (FAQ)

Q: Can I use LM561C parts as a direct replacement for the LM561B Plus?

A: Yes. Both series deliver identical luminous flux (35 lm) and color temperature (6500K) at the specified test current of 65mA. The LM561C operates at lower forward voltage (2.75V versus 2.95V) and exhibits superior thermal characteristics. Circuit designs must accommodate the 0.20V voltage difference if forward voltage is a critical design parameter.

Q: What is the difference between the various LM561B Plus part numbers (WAP0S5, WAPKS5, WAPMS5, WAPSS5)?

A: These designations represent different packaging and tape configurations within the Tape & Reel format. All four variants are electrically and optically identical to the original SPMWHT541MP5WAPNS5. Selection depends on your procurement system's compatibility with specific tape specifications and reel formats.

Q: Are all substitute parts available in the same packaging as the original?

A: The original SPMWHT541MP5WAPNS5 was supplied in bulk packaging. All active substitute parts are supplied in Tape & Reel (TR) format. The physical component dimensions and form factor (5630, 4-SMD, Flat Leads) remain identical across all variants.

Q: What are the thermal implications of switching to LM561C?

A: The LM561C series exhibits 3°C/W lower thermal resistance (12°C/W versus 15°C/W). At identical operating current (65mA), this results in lower junction temperature rise. The LM561C also permits higher maximum current operation (200mA versus 180mA), providing additional design margin for thermal management.

Q: Do all substitute parts meet the same environmental and compliance standards?

A: All substitute parts are RoHS compliant with identical moisture sensitivity levels (MSL 2A, 4 Weeks). SPMWHT541MP5WAPSS5 carries additional ROHS3 and REACH Unaffected certifications. All parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: Can I mix LM561B Plus and LM561C parts in the same production run?

A: Mixing is permissible if circuit design accommodates the 0.20V forward voltage difference. For applications where forward voltage is tightly controlled or monitored, parts should not be mixed within the same circuit or batch to maintain consistent electrical behavior.
