Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Highest Availability): SPMWHT541MP5WAW0S4 is the recommended primary substitute. It maintains identical electrical and mechanical specifications to the main part, carries Active product status, holds the largest inventory (45,709 pcs), and is ROHS3 Compliant, providing superior compliance posture for new designs.

Secondary Substitute (Enhanced Thermal Performance): SPMWHT541MP5WAWGS4 and SPMWHT541MP5WAWSS4 both feature improved thermal resistance (14°C/W versus 16°C/W on the main part), resulting in lower junction temperatures under identical operating conditions. Both maintain Active status. SPMWHT541MP5WAWSS4 carries ROHS3 Compliant certification.

Alternative with Dimensional Variation: SPMWHT541MP5WAWMS4 is electrically and functionally equivalent but features a slightly larger length dimension (5.60mm versus 5.00mm). This part carries Active status and maintains 15°C/W thermal resistance. Use only if PCB layout accommodates the increased length.

Inventory-Constrained Applications: SPMWHT541MP5WAWGS4, SPMWHT541MP5WAWKS4, SPMWHT541MP5WAWNS4, and SPMWHT541MP5WAWSS4 are suitable alternatives with lower inventory levels (726–1,008 pcs). All maintain Active product status and full electrical equivalence.

Compliance Considerations: All substitute parts are RoHS Compliant or ROHS3 Compliant. SPMWHT541MP5WAW0S4 and SPMWHT541MP5WAWSS4 carry ROHS3 Compliant designation, offering enhanced regulatory alignment for applications requiring the highest compliance standards.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAWMS4 be used as a direct replacement for SPMWHT541MP5WAWHS4?

A: Yes. SPMWHT541MP5WAWMS4 is electrically and functionally equivalent. The only difference is the length dimension (5.60mm versus 5.00mm). Verify that your PCB layout and mechanical assembly accommodate the increased length before substitution.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 Compliant represents the current version of the directive with updated substance restrictions. Parts marked ROHS3 Compliant are suitable for applications requiring the latest regulatory compliance.

Q: Are all substitute parts suitable for new designs?

A: Yes. All listed substitute parts carry Active product status, making them appropriate for new design implementations. The main part (SPMWHT541MP5WAWHS4) is marked "Not For New Designs" and should be replaced with an active equivalent in new applications.

Q: What is the thermal resistance difference between the main part and substitutes?

A: The main part has 16°C/W thermal resistance. Substitutes range from 14–15°C/W. Lower thermal resistance improves heat dissipation, resulting in lower junction temperatures. This is beneficial for high-reliability applications or environments with elevated ambient temperatures.

Q: Can I use SPMWHT541MP5WAWGS4 in place of SPMWHT541MP5WAWHS4 without circuit modifications?

A: Yes. SPMWHT541MP5WAWGS4 maintains identical electrical parameters (2.95V forward voltage, 65mA test current, 31 lm flux, 2700K CCT) and mechanical specifications (5630 package, 4-SMD flat leads, 120° viewing angle). No circuit modifications are required.

Q: Which substitute offers the best thermal performance?

A: SPMWHT541MP5WAWGS4 and SPMWHT541MP5WAWSS4 both offer 14°C/W thermal resistance, representing the lowest thermal resistance among all listed parts. This provides optimal heat dissipation compared to the main part (16°C/W) and other substitutes (15°C/W).

Q: Is inventory availability a factor in selecting a substitute?

A: Yes. SPMWHT541MP5WAW0S4 has the highest inventory (45,709 pcs), ensuring immediate availability for production. If inventory is critical for your supply chain, this part is the preferred choice. Other substitutes have lower inventory levels (726–1,008 pcs) and may require longer lead times.

Q: Are all substitute parts packaged in Tape & Reel format?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging with Moisture Sensitivity Level 2A (4 Weeks), matching the main part's packaging specifications.

Q: What is the CRI value, and why does it matter?

A: CRI (Color Rendering Index) is 80 for all parts listed. This indicates the ability of the light source to accurately render colors compared to a reference light source. A CRI of 80 is suitable for general lighting applications where moderate color accuracy is acceptable.

Q: Can I mix different substitute part numbers in the same production batch?

A: Yes. All substitute parts are electrically and mechanically equivalent and deliver identical optical performance (31 lm at 2700K with 120° viewing angle). Mixing part numbers in the same batch does not affect circuit performance or reliability.
