Substitute Part Grouping Explanation

Substitute parts are grouped into two categories based on electrical and mechanical compatibility:

Parametric Equivalents (Identical Electrical Performance): SPMWHT541ML5XAP0S0, SPMWHT541ML5XAP0S6, SPMWHT541ML5XAPKS6, and SPMWHT541ML5XAPMS6 are direct parametric equivalents. These parts maintain identical specifications across all critical parameters: LM561C series, 6500K color temperature, 36 lm flux output, 2.75V forward voltage, 65mA test current, 201 lm/W efficiency, 80 CRI, 120° viewing angle, 5630 package format, and 12°C/W thermal resistance. The differences in part number suffixes reflect packaging lot codes and traceability designations only. All four parts carry Active product status and RoHS Compliant certification.

Similar Substitute (Different Electrical Characteristics): SPMWHT541MP5WAPKS4 is classified as a similar substitute rather than a parametric equivalent. This part belongs to the LM561B Plus series and introduces measurable electrical differences: forward voltage increases to 2.95V (from 2.75V), flux output decreases to 33 lm (from 36 lm), and lumens/watt efficiency decreases to 167 lm/W (from 201 lm/W). Maximum current rating also decreases to 180mA (from 200mA), and thermal resistance increases to 15°C/W (from 12°C/W). Color temperature, viewing angle, package format, and physical dimensions remain identical. This part carries Active product status and ROHS3 Compliant certification.

Key Parameters Determining Substitution:

Color and CCT (6500K cool white)
Flux output range (34–38 lm at 65mA)
Forward voltage tolerance
Package format (5630, 4-SMD, Flat Leads)
Physical dimensions (5.00 × 3.00 × 0.80 mm max)
Viewing angle (120°)
CRI (80)

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

Select SPMWHT541ML5XAP0S0, SPMWHT541ML5XAP0S6, SPMWHT541ML5XAPKS6, or SPMWHT541ML5XAPMS6 when the SPMWHT541ML5XAPGS0 reaches end-of-stock. These four parts are electrically and mechanically identical to the main part and carry Active product status, ensuring long-term supply availability. All four maintain RoHS Compliant certification. Selection among these four equivalents may be based on inventory availability and packaging lot requirements. SPMWHT541ML5XAPKS6 currently has the highest inventory level (5200 pcs).

For Performance-Modified Replacement (Similar Substitute):

SPMWHT541MP5WAPKS4 (LM561B Plus series) is suitable only when the application can tolerate the following electrical changes: increased forward voltage (2.95V vs. 2.75V), reduced flux output (33 lm vs. 36 lm), reduced efficiency (167 lm/W vs. 201 lm/W), and reduced maximum current rating (180mA vs. 200mA). This part carries Active product status and ROHS3 Compliant certification. Circuit design modifications may be required to accommodate the higher forward voltage. This substitute is appropriate for cost-optimization scenarios where the performance reduction is acceptable to the application requirements.

Compliance Considerations:

All substitute parts maintain RoHS compliance. The parametric equivalents retain RoHS Compliant status matching the main part. SPMWHT541MP5WAPKS4 carries ROHS3 Compliant certification, which is a more recent RoHS standard revision and remains acceptable for most applications. MSL rating (2A, 4 Weeks) is consistent across all parts.

Q: Can SPMWHT541MP5WAPKS4 be used as a direct drop-in replacement?

A: SPMWHT541MP5WAPKS4 is mechanically compatible (same 5630 package, dimensions, and mounting type) but electrically different. Circuit modifications may be necessary to accommodate the higher forward voltage and reduced current rating. This part is suitable only when the application can tolerate reduced light output and efficiency.

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

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging with identical 5630 supplier device package format, 4-SMD flat leads configuration, and physical dimensions (5.00 × 3.00 × 0.80 mm max).

Q: What is the inventory status of the substitute parts?

A: SPMWHT541ML5XAPKS6 has the highest inventory (5200 pcs). SPMWHT541ML5XAP0S6 has 938 pcs, SPMWHT541ML5XAPMS6 has 901 pcs, SPMWHT541ML5XAP0S0 has 935 pcs, and SPMWHT541MP5WAPKS4 has 48,482 pcs in stock.
