Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541ML7XAPGS0 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Color and CCT: White, Cool 6500K
• Package Type: 4-SMD, Flat Leads (5630)
• Mounting Type: Surface Mount
• Viewing Angle: 120°
• CRI: 90
• Physical Dimensions: 5.00mm × 3.00mm × 0.80mm maximum height
• RoHS Compliance and MSL Rating

Allowable Variation Parameters:

• Forward Voltage (Vf): Within typical operating range for cool white LEDs (2.75V–2.95V)
• Flux Output: Variation acceptable within application tolerance
• Maximum Current Rating: May differ if test current remains 65mA
• Thermal Resistance: Minor variation acceptable (12–15°C/W range)
• Product Status: Active status preferred for new applications; Not For New Designs acceptable for legacy support

Two substitute parts meet these criteria and are grouped as follows:

Group 1 – Parametric Equivalent (Identical Electrical Performance): SPMWHT541ML7XAP0S0 – Direct parametric match with Active product status

Group 2 – Similar Substitute (Enhanced Performance, Different Series): SPMWHT541MP7WAP0S0 – LM561B Plus series with improved efficiency and Active status

Engineering Selection Recommendations

For Direct Replacement (Legacy Support): Select SPMWHT541ML7XAP0S0 when the original SPMWHT541ML7XAPGS0 is required for existing designs or inventory replenishment. This part is a parametric equivalent with identical electrical and thermal characteristics. The Active product status ensures continued availability and manufacturing support from Samsung Semiconductor. No circuit modifications are required.

For Design Updates or New Applications: Select SPMWHT541MP7WAP0S0 when transitioning to Active product lines. This LM561B Plus series substitute maintains color temperature (6500K), CRI (90), package geometry (5630), and viewing angle (120°) compatibility. The forward voltage increase from 2.75V to 2.95V requires circuit verification for current-limiting resistor values. The maximum current rating of 180mA (versus 200mA) must be confirmed against application requirements. The thermal resistance increase to 15°C/W is acceptable for most surface mount applications with standard PCB thermal management.

Compliance Considerations: All three parts are RoHS Compliant with MSL 2A (4 Weeks) rating. Moisture sensitivity handling procedures must be followed during storage and assembly. ECCN classification (EAR99) and HTSUS code (8541.41.0000) remain consistent across all substitutes.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WAP0S0 be used as a direct drop-in replacement for SPMWHT541ML7XAPGS0?

A: SPMWHT541MP7WAP0S0 is mechanically and functionally compatible in the 5630 package footprint. However, the forward voltage difference (2.95V versus 2.75V) requires circuit analysis. If the original design uses a fixed current-limiting resistor, the resistor value must be recalculated to maintain 65mA test current. The maximum current rating reduction from 200mA to 180mA must be verified against application peak current demands.

Q: What is the difference between SPMWHT541ML7XAPGS0 and SPMWHT541ML7XAP0S0?

A: Both parts are LM561C series with identical electrical parameters (2.75V, 65mA, 29 lumens, 90 CRI). The primary difference is product status: SPMWHT541ML7XAPGS0 is Not For New Designs, while SPMWHT541ML7XAP0S0 is Active. For new designs or long-term supply assurance, SPMWHT541ML7XAP0S0 is the recommended choice.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the 4-SMD, Flat Leads (5630) package with identical dimensions (5.00mm × 3.00mm × 0.80mm maximum height). PCB footprints and solder pad layouts are interchangeable.

Q: What is the impact of the thermal resistance difference between the main part (12°C/W) and SPMWHT541MP7WAP0S0 (15°C/W)?

A: The 3°C/W increase in thermal resistance results in higher junction temperature under the same power dissipation. At 65mA and 2.95V, power dissipation is approximately 192mW. The temperature rise difference is approximately 0.58°C. This is acceptable for most applications with standard PCB thermal management. High-temperature environments or continuous maximum current operation may require thermal analysis.

Q: Are moisture sensitivity levels identical across all substitutes?

A: Yes. All three parts carry MSL 2A (4 Weeks) rating. Storage conditions, handling procedures, and reflow soldering parameters must comply with IPC-A-610 standards for MSL 2A components.

Q: Can SPMWHT541MP7WAP0S0 operate at the same 200mA maximum current as the original part?

A: No. SPMWHT541MP7WAP0S0 has a maximum current rating of 180mA, compared to 200mA for SPMWHT541ML7XAPGS0. Applications requiring operation above 180mA must use SPMWHT541ML7XAP0S0 or the original part.

Q: What is the lumen output difference between the main part and SPMWHT541MP7WAP0S0?

A: At 65mA test current, SPMWHT541ML7XAPGS0 produces 29 lumens (26–32 lm range), while SPMWHT541MP7WAP0S0 produces 27 lumens (24–30 lm range). The 2-lumen reduction represents approximately 7% lower output. Applications with strict luminous intensity requirements must account for this difference.
