Parameter Comparison

Engineering Selection Recommendations

SPMWHT541ML5XAWMS5 (Primary Equivalent)

This part is the direct parametric equivalent to SPMWHT541ML5XAW0S5. Both are LM561C series devices with identical electrical and mechanical specifications. SPMWHT541ML5XAWMS5 carries ROHS3 Compliant status compared to RoHS Compliant on the main part, representing enhanced regulatory compliance. This substitute is suitable for direct replacement in all applications where the main part is specified. Product status is Active, confirming ongoing availability and support.

SPMWHT541MP5WAWMS5 (Series Upgrade Alternative)

This part represents an upgrade within the LM561 family, utilizing the LM561B Plus series. It maintains identical optical output (33lm at 65mA), color temperature (2700K), and mechanical compatibility. The forward voltage increases from 2.75V to 2.95V, and maximum current rating decreases from 200mA to 180mA. Thermal resistance increases from 12°C/W to 15°C/W. Lumens/Watt efficiency is 172 lm/W compared to 185 lm/W on the main part. This substitute is suitable for applications where the higher forward voltage and reduced maximum current are acceptable within circuit design parameters. Product status is Active with ROHS3 Compliant certification.

SPMWHT541MP5WAWUS5 (Legacy Alternative)

This part is electrically and mechanically identical to SPMWHT541MP5WAWMS5 (LM561B Plus series). However, product status is designated as "Not For New Designs," indicating this part is in end-of-life phase. This substitute is suitable only for replacement or maintenance of existing designs and is not recommended for new product development. RoHS Compliant status is maintained.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XAWMS5 be used as a direct replacement for SPMWHT541ML5XAW0S5?

A: Yes. Both parts are LM561C series devices with identical electrical specifications (2.75V forward voltage, 65mA test current, 33lm output), mechanical dimensions (5.00mm × 3.00mm, 0.80mm height), and thermal characteristics (12°C/W). The only difference is enhanced RoHS3 compliance on the substitute part.

Q: What are the key differences between LM561C and LM561B Plus series substitutes?

A: The LM561B Plus series (SPMWHT541MP5WAWMS5 and SPMWHT541MP5WAWUS5) operates at 2.95V forward voltage compared to 2.75V on LM561C. Maximum current rating is 180mA versus 200mA. Thermal resistance is 15°C/W versus 12°C/W. Lumens/Watt efficiency is 172 lm/W versus 185 lm/W. All other parameters including optical output (33lm), color temperature (2700K), viewing angle (120°), and mechanical dimensions remain identical.

Q: Are all substitute parts mechanically compatible with the original part?

A: Yes. All substitute parts use the 5630 package format with 4-SMD flat leads, identical dimensions of 5.00mm × 3.00mm, and maximum seated height of 0.80mm. All are surface mount components in Tape & Reel packaging with MSL 2A (4 Weeks) moisture sensitivity.

Q: Which substitute part should be selected for new product designs?

A: SPMWHT541ML5XAWMS5 or SPMWHT541MP5WAWMS5 are both suitable for new designs, as both carry Active product status. SPMWHT541MP5WAWUS5 is designated "Not For New Designs" and should not be selected for new product development.

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

A: The main part and SPMWHT541ML5XAWMS5 operate at 2.75V. The LM561B Plus substitutes (SPMWHT541MP5WAWMS5 and SPMWHT541MP5WAWUS5) operate at 2.95V. This 0.20V difference affects power supply design and current limiting resistor calculations. Circuits designed for 2.75V operation require recalculation if substituting with 2.95V parts.

Q: Are there differences in thermal management between substitute options?

A: Yes. The main part and SPMWHT541ML5XAWMS5 have thermal resistance of 12°C/W. The LM561B Plus substitutes have thermal resistance of 15°C/W. This 3°C/W difference affects junction temperature rise under identical operating conditions and may impact thermal design in high-density applications.

Q: What is the significance of RoHS compliance variations?

A: SPMWHT541ML5XAW0S5 and SPMWHT541MP5WAWUS5 carry RoHS Compliant status. SPMWHT541ML5XAWMS5 and SPMWHT541MP5WAWMS5 carry ROHS3 Compliant status, representing enhanced regulatory compliance with more stringent restrictions on hazardous substances. Both compliance levels are acceptable for most applications; ROHS3 provides additional assurance for regulated markets.

Q: Can the maximum current rating difference affect part selection?

A: Yes. The main part and SPMWHT541ML5XAWMS5 support maximum current of 200mA. The LM561B Plus substitutes support maximum current of 180mA. Applications requiring operation above 180mA must use the LM561C series parts. Conversely, applications operating below 180mA can use either series.
