Engineering Selection Recommendations

Primary Substitutes (Active Status):

SPMWHT541MP5WAVMS5 is the preferred substitute for new designs. This part maintains identical electrical specifications to the main part (LM561B Plus series, 2.95V Vf, 177 lm/W) while offering ROHS3 compliance and significantly higher inventory availability (26,898 units). It is suitable for direct replacement in active production and new design implementations.

SPMWHT541ML5XAVMS5 is an alternative substitute offering improved thermal performance (12°C/W versus 15°C/W) and higher efficiency (190 lm/W versus 177 lm/W) through the LM561C series. This part carries ROHS3 compliance and the highest inventory level (10,671 units). The lower forward voltage (2.75V) requires circuit verification but provides operational advantages in power-sensitive applications.

SPMWHT541ML5XAV0S5 is functionally equivalent to SPMWHT541ML5XAVMS5 with identical LM561C specifications and thermal characteristics. RoHS compliance is standard. Inventory is lower (992 units), making it a secondary choice when SPMWHT541ML5XAVMS5 is unavailable.

Secondary Substitute (Legacy Status):

SPMWHT541MP5WAVUS5 carries a "Not For New Designs" product status and should be used only for legacy system maintenance or repair applications. It maintains LM561B Plus specifications identical to the main part but offers no design advantages. Inventory is available (11,711 units) for replacement purposes only.

Compliance Considerations:

All substitute parts meet MSL 2A (4 Weeks) moisture sensitivity requirements. ROHS3-compliant variants (SPMWHT541ML5XAVMS5 and SPMWHT541MP5WAVMS5) are preferred for new designs requiring enhanced regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAVMS5 (LM561C) replace SPMWHT541MP5WAVNS5 (LM561B Plus) directly?

A: Yes. Both parts share identical color temperature (3000K), flux output (34 lm), viewing angle (120°), package dimensions (5630, 5.00 × 3.00 mm), and CRI (80). The LM561C variant operates at 2.75V forward voltage versus 2.95V, which is within acceptable tolerance for most circuit designs. The improved thermal resistance (12°C/W) and efficiency (190 lm/W) provide operational benefits. Verify circuit voltage compliance before implementation.

Q: What is the difference between SPMWHT541MP5WAVMS5 and SPMWHT541MP5WAVUS5?

A: Both parts are LM561B Plus series with identical electrical specifications (2.95V Vf, 177 lm/W, 180mA max). The primary difference is product status: SPMWHT541MP5WAVMS5 is Active and carries ROHS3 compliance, suitable for new designs. SPMWHT541MP5WAVUS5 is marked "Not For New Designs" and should be used only for legacy system maintenance. Inventory availability differs significantly (26,898 units versus 11,711 units).

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

A: Yes. All substitute parts use the 4-SMD, Flat Leads package (5630) with identical dimensions (5.00 × 3.00 mm) and maximum seated height (0.80 mm). PCB footprints and reflow profiles require no modification.

Q: Which substitute offers the best thermal performance?

A: SPMWHT541ML5XAVMS5 and SPMWHT541ML5XAV0S5 (both LM561C series) provide superior thermal resistance at 12°C/W compared to 15°C/W for LM561B Plus variants. This 3°C/W improvement reduces junction temperature rise in high-current or high-ambient applications.

Q: What is the impact of forward voltage differences between LM561B Plus (2.95V) and LM561C (2.75V)?

A: The 0.20V difference affects circuit power dissipation and current-limiting resistor calculations. LM561C's lower forward voltage reduces power consumption by approximately 6.8% at 65mA test current. Verify that existing current-limiting circuits accommodate the lower voltage without exceeding maximum current ratings (200mA for LM561C, 180mA for LM561B Plus).

Q: Can I use SPMWHT541MP5WAVUS5 in new product designs?

A: No. This part carries "Not For New Designs" status and should be reserved for legacy system repairs and maintenance only. Use SPMWHT541MP5WAVMS5 or SPMWHT541ML5XAVMS5 for new designs.

Q: What does ROHS3 compliance mean compared to standard RoHS compliance?

A: ROHS3 represents enhanced regulatory compliance with stricter restrictions on hazardous substances. All substitute parts meet either RoHS or ROHS3 standards. ROHS3-compliant variants (SPMWHT541ML5XAVMS5 and SPMWHT541MP5WAVMS5) are preferred for applications requiring advanced environmental compliance documentation.

Q: Is the 34 lumen output guaranteed across all substitute parts?

A: Yes. All substitute parts specify 34 lumens at 25°C with 65mA test current, with a tolerance range of 33–35 lumens. This ensures consistent brightness output across all equivalent parts.
