Substitute Classification:

Parametric Equivalents (LM561C Series): SPMWHT541ML7XAV0S0, SPMWHT541ML7XAVMS0, and SPMWHT541ML7XAVSS0 are direct parametric equivalents. All three parts share identical electrical and optical specifications with the main part, including 2.75V forward voltage, 28 lumens output, 157 lm/W efficiency, and 12°C/W thermal resistance. These parts differ only in packaging tape configuration (indicated by suffix variations) and are fully interchangeable at the component level.

Similar Substitute (LM561B Plus Series): SPMWHT541MP7WAVMS0 represents a functional substitute from the LM561B Plus series. While maintaining the same 3000K color temperature, 120° viewing angle, and 5630 package format, this part operates at 2.95V forward voltage (0.20V higher) and delivers 26 lumens at 65mA test current. The thermal resistance increases to 15°C/W, and maximum current is rated at 180mA. This part is suitable for applications where the higher forward voltage and slightly reduced luminous output are acceptable within circuit design margins.

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

SPMWHT541ML7XAV0S0, SPMWHT541ML7XAVMS0, and SPMWHT541ML7XAVSS0 are recommended as primary substitutes for the SPMWHT541ML7XAVKS0. All three parts maintain active product status and deliver identical electrical and optical performance. These parts are fully compatible with existing circuit designs without modification. Selection among these three equivalents should be based on tape reel configuration availability and supply chain logistics. All three carry RoHS Compliance certification and identical moisture sensitivity ratings.

For Functional Substitution (LM561B Plus Alternative):

SPMWHT541MP7WAVMS0 is suitable as a functional substitute when the LM561C parametric equivalents are unavailable. This part operates at 2.95V forward voltage, which is 0.20V higher than the main part. Circuit designs must accommodate this voltage increase within power supply and current-limiting resistor calculations. The luminous output is 26 lumens compared to 28 lumens, representing a 7% reduction in light output. The thermal resistance increases from 12°C/W to 15°C/W, requiring thermal management evaluation in high-current applications. This part carries ROHS3 Compliance, which exceeds the RoHS Compliant status of the main part.

Product Status Consideration:

The main part SPMWHT541ML7XAVKS0 is designated "Not For New Designs." All substitute parts listed carry "Active" product status, ensuring long-term availability and continued manufacturing support. For new production runs or design revisions, selection of an active substitute part is strongly advised to avoid future obsolescence.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML7XAV0S0, SPMWHT541ML7XAVMS0, and SPMWHT541ML7XAVSS0 be used interchangeably with SPMWHT541ML7XAVKS0?

A: Yes. These three parts are parametric equivalents with identical electrical specifications (2.75V forward voltage, 28 lumens, 157 lm/W), optical properties (3000K, 90 CRI, 120° viewing angle), and package dimensions (5630, 5.00mm × 3.00mm × 0.80mm). Differences exist only in tape reel packaging configuration. No circuit modifications are required.

Q: What is the difference between the LM561C and LM561B Plus series?

A: The LM561B Plus series (SPMWHT541MP7WAVMS0) operates at 2.95V forward voltage versus 2.75V for LM561C. At 65mA test current, LM561B Plus delivers 26 lumens compared to 28 lumens for LM561C. Thermal resistance is 15°C/W for LM561B Plus versus 12°C/W for LM561C. Both maintain 3000K color temperature, 90 CRI, and 120° viewing angle. Maximum current rating is 180mA for LM561B Plus versus 200mA for LM561C.

Q: Can SPMWHT541MP7WAVMS0 be used as a direct replacement without circuit modification?

A: No. The 0.20V higher forward voltage requires recalculation of current-limiting resistor values and power supply voltage margins. The 2-lumen reduction in output may affect brightness-critical applications. Thermal management must be re-evaluated due to the 3°C/W increase in thermal resistance. Circuit validation is required before implementation.

Q: Are all substitute parts RoHS compliant?

A: Yes. SPMWHT541ML7XAV0S0, SPMWHT541ML7XAVMS0, and SPMWHT541ML7XAVSS0 carry RoHS Compliant certification. SPMWHT541MP7WAVMS0 carries ROHS3 Compliant certification, which represents an enhanced compliance standard. All parts meet regulatory requirements for hazardous substance restrictions.

Q: What does the tape reel suffix variation mean?

A: The suffixes in SPMWHT541ML7XAV0S0, SPMWHT541ML7XAVMS0, and SPMWHT541ML7XAVSS0 indicate different tape reel packaging configurations used during automated assembly. These variations do not affect component performance or electrical characteristics. Selection is based on compatibility with pick-and-place equipment and supply chain availability.

Q: Is the main part SPMWHT541ML7XAVKS0 still available?

A: The main part is listed as "Not For New Designs," indicating end-of-life status. Existing inventory of 990 pieces is available, but long-term availability is not guaranteed. For ongoing production, migration to an active substitute part is recommended.

Q: What is the moisture sensitivity level (MSL) and why does it matter?

A: All listed parts carry MSL 2A (4 Weeks), indicating the component can be stored in dry conditions for up to 4 weeks before soldering. After this period, the component must be baked at specified temperature and humidity conditions before use. Proper storage in dry cabinets or desiccant packaging is required to maintain component reliability.

Q: Can these LED parts be operated at currents higher than 65mA?

A: Yes, within maximum current ratings. SPMWHT541ML7XAVKS0, SPMWHT541ML7XAV0S0, SPMWHT541ML7XAVMS0, and SPMWHT541ML7XAVSS0 support up to 200mA. SPMWHT541MP7WAVMS0 supports up to 180mA. Higher current operation increases luminous output and heat generation. Thermal management and forward voltage drop must be recalculated for non-standard operating points.
