SPMWHT541ML7XAWNS0 Equivalent & Substitute Parts

Part Overview

The SPMWHT541ML7XAWNS0 is a Samsung Semiconductor LM561C warm white LED in 5630 surface mount package configuration. This component is classified as Not For New Designs, indicating it has reached end-of-life status. The part delivers 27 lumens at 65mA test current with a forward voltage of 2.75V and 120° viewing angle. Due to its discontinued design status, equivalent substitute parts from the active LM561C series and the newer LM561B Plus series are available to maintain design continuity and support existing applications requiring warm white 2700K LED solutions.

Substitute Part Grouping Explanation

Substitute parts for the SPMWHT541ML7XAWNS0 are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents (LM561C Series): Parts SPMWHT541ML7XAW0S0, SPMWHT541ML7XAWMS0, and SPMWHT541ML7XAWSS0 are direct parametric equivalents sharing identical electrical specifications with the main part. These components maintain the same forward voltage (2.75V), luminous flux (27lm at 65mA), efficiency (151 lm/W), maximum current rating (200mA), thermal resistance (12°C/W), and physical package dimensions. The primary difference is product status: these parts are Active, whereas the main part is Not For New Designs. All three parametric equivalents are RoHS Compliant with 2A MSL rating.

Similar Substitute (LM561B Plus Series): Part SPMWHT541MP7WAWMS0 represents a functional alternative from the newer LM561B Plus series. While maintaining identical color temperature (2700K), viewing angle (120°), package type (4-SMD, Flat Leads, 5630), and physical dimensions, this part differs in forward voltage (2.95V versus 2.75V), luminous flux (25lm versus 27lm at 65mA), efficiency (130 lm/W versus 151 lm/W), maximum current (180mA versus 200mA), and thermal resistance (15°C/W versus 12°C/W). This part is Active and ROHS3 Compliant.

Substitution is permitted when the application requirements allow for the specified electrical and thermal parameter variations.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: Select SPMWHT541ML7XAW0S0, SPMWHT541ML7XAWMS0, or SPMWHT541ML7XAWSS0 when exact electrical and thermal performance matching is required. These parametric equivalents from the active LM561C series provide identical specifications to the discontinued SPMWHT541ML7XAWNS0. All three options are Active products with RoHS Compliant certification, ensuring long-term availability and regulatory compliance. Selection among these three equivalents may be based on inventory availability or packaging reel specifications.

For Alternative Performance Profile: Select SPMWHT541MP7WAWMS0 when the application can accommodate the specified parameter variations. This LM561B Plus series part is suitable for designs where the 0.20V higher forward voltage, 2 lumen lower flux output, 21 lm/W lower efficiency, 20mA lower maximum current rating, and 3°C/W higher thermal resistance are acceptable. This part is Active and ROHS3 Compliant, providing enhanced regulatory compliance for new designs.

Compliance Considerations: All substitute parts maintain the required 2A MSL rating and are suitable for tape and reel packaging applications. The LM561B Plus option provides ROHS3 certification, which may be preferred for applications with enhanced environmental compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML7XAW0S0, SPMWHT541ML7XAWMS0, and SPMWHT541ML7XAWSS0 be used interchangeably with SPMWHT541ML7XAWNS0?

A: Yes. These three parts are parametric equivalents with identical electrical specifications, including forward voltage (2.75V), luminous flux (27lm at 65mA), efficiency (151 lm/W), maximum current (200mA), thermal resistance (12°C/W), and physical package dimensions. The primary distinction is that these parts are Active products, whereas the main part is Not For New Designs. All three are suitable for direct replacement in existing designs.

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

A: The LM561B Plus series (SPMWHT541MP7WAWMS0) differs from the LM561C series in forward voltage (2.95V versus 2.75V), luminous flux (25lm versus 27lm at 65mA), efficiency (130 lm/W versus 151 lm/W), maximum current rating (180mA versus 200mA), and thermal resistance (15°C/W versus 12°C/W). Both series maintain identical color temperature (2700K), CRI (90), viewing angle (120°), and physical package dimensions (5630, 4-SMD, Flat Leads).

Q: Is the SPMWHT541MP7WAWMS0 a suitable substitute for the main part?

A: The SPMWHT541MP7WAWMS0 is a functional alternative when the application requirements allow for the specified electrical and thermal parameter variations. The higher forward voltage and lower efficiency may impact circuit design and thermal management. Verify that the application circuit can accommodate the 0.20V voltage increase and that thermal dissipation requirements are compatible with the 3°C/W higher thermal resistance.

Q: Are all substitute parts available in tape and reel packaging?

A: Yes. All substitute parts listed are supplied in Tape & Reel (TR) packaging configuration, maintaining compatibility with automated assembly processes.

Q: What is the significance of the product status designation?

A: Product Status indicates the component's lifecycle stage. "Not For New Designs" indicates the main part is discontinued and should not be used in new applications. "Active" status indicates the substitute parts are in current production and recommended for new designs. This distinction affects long-term availability and supplier support.

Q: Do all parts meet RoHS compliance requirements?

A: The parametric equivalents (SPMWHT541ML7XAW0S0, SPMWHT541ML7XAWMS0, SPMWHT541ML7XAWSS0) are RoHS Compliant. The LM561B Plus alternative (SPMWHT541MP7WAWMS0) is ROHS3 Compliant, providing enhanced environmental compliance certification.

Q: What is the MSL rating and why is it important?

A: All parts carry a 2A MSL (Moisture Sensitivity Level) rating with a 4-week floor life. This indicates the component requires controlled storage conditions and has a specified time limit after moisture barrier bag opening. Proper handling and storage procedures must be followed to maintain component reliability.
