Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPMWHT541MP5WAWNS5 is determined by the following critical parameters:

Primary Substitution Criteria:

• Color and CCT (2700K warm white)
• Flux output range (32lm ~ 34lm @ 25°C, 65mA test current)
• CRI rating (80 minimum)
• Viewing angle (120°)
• Package type (4-SMD, Flat Leads, 5630)
• Physical dimensions (5.00mm x 3.00mm x 0.80mm max height)
• Mounting type (Surface Mount)
• MSL rating (2A, 4 Weeks)

Secondary Compatibility Parameters:

• Forward voltage tolerance (2.75V to 2.95V acceptable range)
• Maximum current rating (180mA or higher)
• Thermal resistance (12°C/W to 15°C/W)
• RoHS compliance status (RoHS Compliant or ROHS3 Compliant)

Parts meeting all primary criteria and at least one secondary criterion are classified as parametric equivalents. Parts with identical specifications across all parameters are classified as direct equivalents.

Parameter Comparison

Engineering Selection Recommendations

SPMWHT541MP5WAWMS5 is the primary recommended substitute for SPMWHT541MP5WAWNS5. Both parts share identical electrical specifications (2.95V forward voltage, 172 lm/W efficiency, 180mA maximum current) and mechanical compatibility (5630 package, 120° viewing angle, identical dimensions). SPMWHT541MP5WAWMS5 carries ROHS3 Compliant certification, representing updated compliance status relative to the RoHS Compliant main part. Inventory availability is significantly higher (23,477 pcs vs. 631 pcs), supporting production continuity.

SPMWHT541ML5XAWMS5 is a parametric equivalent suitable for applications where improved thermal performance is beneficial. This LM561C series part features 12°C/W thermal resistance (improved from 15°C/W), 200mA maximum current rating (vs. 180mA), and 184 lm/W efficiency (vs. 172 lm/W). Forward voltage is 2.75V, representing a 0.20V reduction. All other parameters (flux output, CRI, viewing angle, package, dimensions, MSL) remain identical. ROHS3 Compliant certification applies. This substitution is appropriate for designs requiring enhanced thermal management or higher current headroom.

SPMWHT541MP5WAWUS5 shares identical electrical and mechanical specifications with the main part but carries "Not For New Designs" product status. This part is suitable only for legacy design support or replacement applications where existing inventory must be maintained. ROHS3 Compliant certification applies. New designs should not incorporate this part number.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAWMS5 replace SPMWHT541MP5WAWNS5 in existing designs?

A: Yes. Both parts deliver identical flux output (33lm at 65mA), CRI (80), viewing angle (120°), and package configuration (5630, 4-SMD flat leads). The LM561C series (SPMWHT541ML5XAWMS5) operates at 2.75V forward voltage versus 2.95V for the LM561B Plus series. Circuit designs must accommodate this 0.20V difference in forward voltage. The improved thermal resistance (12°C/W vs. 15°C/W) and higher maximum current rating (200mA vs. 180mA) provide additional design margin.

Q: What is the difference between SPMWHT541MP5WAWMS5 and SPMWHT541MP5WAWUS5?

A: These parts are electrically and mechanically identical. Both are LM561B Plus series with 2.95V forward voltage, 172 lm/W efficiency, and 180mA maximum current. The primary difference is product status: SPMWHT541MP5WAWMS5 is Active, while SPMWHT541MP5WAWUS5 is Not For New Designs. For new product development, SPMWHT541MP5WAWMS5 is the appropriate selection.

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

A: Yes. All substitute parts use the 5630 package with 4-SMD flat leads configuration. Physical dimensions are identical: 5.00mm length x 3.00mm width x 0.80mm maximum seated height. PCB footprints and reflow profiles remain unchanged across all listed substitutes.

Q: What is the impact of forward voltage differences on circuit design?

A: Forward voltage differences affect current-limiting resistor calculations and power supply requirements. SPMWHT541MP5WAWNS5 and SPMWHT541MP5WAWMS5 operate at 2.95V, while SPMWHT541ML5XAWMS5 operates at 2.75V. A 0.20V reduction in forward voltage will increase current draw by approximately 3-5% in constant-current driver circuits. Designs using constant-voltage supplies must recalculate series resistor values to maintain 65mA test current.

Q: Do all substitute parts meet the same moisture sensitivity requirements?

A: Yes. All parts carry MSL 2A rating (4 Weeks maximum floor life at 30°C/60% RH). Handling, storage, and reflow procedures are identical across all part numbers.

Q: Which substitute offers the best thermal performance?

A: SPMWHT541ML5XAWMS5 provides the lowest thermal resistance at 12°C/W, compared to 15°C/W for the main part and other LM561B Plus substitutes. This 3°C/W improvement reduces junction temperature rise by approximately 3°C at 65mA test current, supporting higher ambient temperature operation or increased current headroom.
