Engineering Selection Recommendations

Primary Substitute: SPMWHT541MP5WARMS4

This substitute is suitable for applications currently using SPMWHT541MD5WARMS2 based on the following factors:

• Product Status: The substitute maintains active manufacturing status, ensuring supply continuity and long-term component availability.
• Electrical Compatibility: Identical forward voltage (2.95V) and test current (65mA) enable direct circuit integration without modification.
• Thermal Performance: Superior thermal resistance (15°C/W vs. 16°C/W) provides improved thermal management.
• Compliance Standards: ROHS3 compliance exceeds the original RoHS requirement, confirming environmental and regulatory compliance.
• Performance Enhancement: Higher luminous efficiency (177 lm/W vs. 156 lm/W) and increased flux output deliver superior optical performance within the same thermal budget.

The substitute component is dimensionally compatible within PCB layout tolerances, with maximum height reduced by 0.10mm, presenting no assembly or mechanical interference concerns for standard surface mount processes.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WARMS4 directly replace SPMWHT541MD5WARMS2 in existing designs?

A: Yes. Both components share identical color temperature (5000K), forward voltage (2.95V), test current (65mA), viewing angle (120°), and 5630 package footprint. The substitute requires no circuit modifications for functional equivalence.

Q: What are the key differences between these two parts?

A: The substitute represents an improved product generation (LM561B Plus vs. LM561B) with enhanced efficiency (177 vs. 156 lm/W), higher maximum current rating (180mA vs. 150mA), superior thermal resistance (15°C/W vs. 16°C/W), and increased luminous flux output (34lm vs. 30lm). Physical height is reduced by 0.10mm. Both maintain 120° viewing angle and identical electrical specifications at test current.

Q: Are there packaging format differences between these components?

A: Yes. The original part uses bulk packaging, while the substitute is supplied in Tape & Reel format. This difference affects inventory management and automated assembly compatibility but does not impact component electrical or thermal characteristics.

Q: Is RoHS compliance maintained with the substitute?

A: Yes. While the original is RoHS Compliant, the substitute achieves the more stringent ROHS3 Compliant standard, providing enhanced regulatory coverage.

Q: Are moisture sensitivity ratings identical?

A: Yes. Both components maintain the same MSL 2A (4 Weeks) rating, requiring identical handling and storage protocols.
