Substitute Part Grouping Explanation

Substitute parts for the SPMWHT541MD5WAV0S2 are identified based on the following criteria:

Electrical Compatibility:

• Color and CCT must match: White, Warm 3000K
• Forward voltage must be identical: 2.95V (Typ)
• Test current must be identical: 65mA
• CRI must match: 80
• Viewing angle must match: 120°

Mechanical Compatibility:

• Package type must be compatible: 4-SMD surface mount
• Supplier device package must be identical: 5630
• Physical dimensions must be identical: 5.00mm × 3.00mm
• Height must be within acceptable range for PCB assembly

Thermal & Environmental:

• Thermal resistance must be identical: 16°C/W
• RoHS compliance required
• MSL rating must be 2A or better

Substitutes are grouped into two categories:

1. Parametric Equivalent (Same Electrical Performance): SPMWHT541MD5WAVMS2 — Identical electrical and optical specifications; differs only in packaging format (Cut Tape & Digi-Reel vs. standard packaging).

2. Performance Enhanced Substitute (Improved Efficiency): SPMWHT541MP5WAV0S4 — LM561B Plus variant with higher luminous flux (32 lm vs. 28 lm) and improved efficiency (167 lm/W vs. 146 lm/W) while maintaining identical electrical interface and mechanical form factor.

Engineering Selection Recommendations

For Direct Replacement (Obsolete Part Continuity):

Select SPMWHT541MD5WAVMS2 when exact electrical and optical performance matching is required. This part is a parametric equivalent with identical specifications to the main part. Although also classified as obsolete, it maintains full compatibility with existing designs and PCB layouts. The only difference is packaging format (Cut Tape & Digi-Reel vs. standard), which does not affect component performance or assembly compatibility.

For New Designs or Redesign Opportunities:

Select SPMWHT541MP5WAV0S4 (LM561B Plus) when design flexibility permits. This part is actively manufactured by Samsung, ensuring long-term supply availability. It delivers 14% higher luminous flux (32 lm vs. 28 lm) and 14% higher efficiency (167 lm/W vs. 146 lm/W) while maintaining identical electrical interface (2.95V, 65mA test current) and mechanical form factor (5630, 5.00mm × 3.00mm). The slightly reduced height (0.80mm vs. 0.90mm) and higher maximum current rating (180mA vs. 150mA) provide additional design margin. RoHS compliance and MSL rating are equivalent across all three parts.

Compliance Considerations:

All three parts are RoHS Compliant and carry MSL 2A (4 Weeks) rating. REACH status for the main part is listed as REACH Unaffected. ECCN classification is EAR99 for all parts. HTSUS code is 8541.41.0000 for all parts.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAV0S4 (LM561B Plus) be used as a direct replacement for SPMWHT541MD5WAV0S2?

A: Yes, with design verification. The LM561B Plus maintains identical electrical interface (2.95V forward voltage, 65mA test current) and mechanical compatibility (5630 package, 5.00mm × 3.00mm dimensions). However, the higher luminous flux output (32 lm vs. 28 lm) will increase light output by approximately 14%. Applications requiring exact brightness matching should account for this difference through circuit design adjustments or optical filtering. The reduced height (0.80mm vs. 0.90mm) is beneficial for compact PCB designs.

Q: What is the difference between SPMWHT541MD5WAV0S2 and SPMWHT541MD5WAVMS2?

A: These parts are parametric equivalents with identical electrical, optical, and thermal specifications. The difference is packaging format: SPMWHT541MD5WAV0S2 uses standard packaging, while SPMWHT541MD5WAVMS2 is supplied in Cut Tape & Digi-Reel format. Both are obsolete. Selection depends on procurement and assembly line requirements. Cut Tape & Digi-Reel format is typically used for automated pick-and-place assembly systems.

Q: Why is SPMWHT541MP5WAV0S4 recommended for new designs?

A: SPMWHT541MP5WAV0S4 is actively manufactured (Active product status), ensuring reliable long-term supply compared to obsolete alternatives. It delivers superior performance (14% higher efficiency and flux) while maintaining full electrical and mechanical compatibility. For applications where brightness increase is acceptable, this part eliminates obsolescence risk and provides better value through improved efficiency.

Q: Are there any thermal or reliability differences between these parts?

A: All three parts share identical thermal resistance (16°C/W) and MSL rating (2A, 4 Weeks). Thermal performance and moisture sensitivity handling are equivalent. The LM561B Plus variant achieves higher efficiency through improved die technology, not thermal management changes.

Q: Can these parts be used interchangeably in existing PCB designs?

A: SPMWHT541MD5WAV0S2 and SPMWHT541MD5WAVMS2 are fully interchangeable at the PCB level. SPMWHT541MP5WAV0S4 is mechanically compatible but produces higher light output. PCB layout compatibility is confirmed for all three parts due to identical 5630 package dimensions and lead configuration. Verify that circuit design can accommodate the higher maximum current rating (180mA) of the LM561B Plus if operating at elevated currents.

Q: What is the significance of the "Flat Lead Exposed Pad" vs. "Flat Leads" package designation?

A: Both designations refer to 4-SMD surface mount packages with 5630 form factor. The exposed pad variant (SPMWHT541MD5WAV0S2 and SPMWHT541MD5WAVMS2) includes a thermal pad for enhanced heat dissipation. The flat leads variant (SPMWHT541MP5WAV0S4) uses standard lead configuration. Both are suitable for standard PCB assembly processes. Thermal performance (16°C/W) is identical across all variants.

Q: Are these parts suitable for high-reliability applications?

A: All three parts are RoHS Compliant and carry standard MSL 2A rating. They meet basic environmental compliance requirements. For high-reliability applications, consult Samsung's detailed reliability data sheets and thermal cycling test results. The active product status of SPMWHT541MP5WAV0S4 provides supply chain reliability advantages over obsolete alternatives.
