LED LM561B PLUS NEU WHT 5630 SPMWHT541MP7WATUS0 Equivalent & Substitute Parts

Part Overview

The SPMWHT541MP7WATUS0 is a Samsung Semiconductor LED lighting component from the LM561B Plus series, featuring neutral white 4000K color temperature in a 5630 surface mount package. This part is classified as Not For New Designs, indicating it has been superseded in Samsung's product portfolio. The LM561B Plus series delivers white neutral LED solutions with 90 CRI (Color Rendering Index) for applications requiring consistent color rendering and moderate luminous output. Due to its discontinued status for new designs, equivalent and substitute parts from active product lines are necessary for ongoing production requirements and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SPMWHT541MP7WATUS0 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Color specification: White, Neutral
• Correlated Color Temperature (CCT): 4000K
• Color Rendering Index (CRI): 90
• Viewing Angle: 120°
• Package Type: 4-SMD, Flat Leads
• Supplier Device Package: 5630
• Physical dimensions: 5.00mm x 3.00mm
• Height - Seated (Max): 0.80mm
• Mounting Type: Surface Mount

Secondary Compatibility Parameters:

• Forward Voltage (Vf): 2.9V to 3.0V (acceptable range for circuit design)
• Test Current: 65mA to 150mA (operational current range)
• Maximum Current: 180mA to 200mA (maximum rating tolerance)
• Thermal Resistance: 15°C/W to 25°C/W (thermal management consideration)

Compliance Requirements:

• RoHS3 Compliant status preferred for new designs
• REACH Unaffected status for regulatory alignment

Substitute parts are grouped into two categories: Direct Equivalent (same series, active status) and Parametric Equivalent (different series, compatible electrical and mechanical specifications).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection:

SPMWHT541MP7WATMS0 is the primary direct equivalent for SPMWHT541MP7WATUS0. Both components belong to the LM561B Plus series and maintain identical electrical and mechanical specifications. The direct equivalent offers improved compliance status (ROHS3 Compliant versus RoHS Compliant) and superior thermal performance (15°C/W versus 20°C/W thermal resistance). Significantly higher inventory availability (43274 units) supports production continuity. This part is classified as Active, eliminating design obsolescence concerns.

Parametric Equivalent Selection:

The LM281B+ series parts (SPMWH1228FD7W2T0SJ, SPMWH1228FD7W2TKSJ, SPMWH1228FD7W2TMSJ, SPMWH1228FD7WAT0SJ, SPMWH1228FD7WATKSJ, SPMWH1228FD7WATMSJ) provide functional substitution when direct equivalents are unavailable. These parts maintain identical color temperature (4000K), CRI (90), viewing angle (120°), package configuration (4-SMD, Flat Leads, 5630), and physical dimensions. Forward voltage ranges from 2.9V to 3.0V, representing a 0.05V to 0.05V variance from the main part's 2.95V specification. Test current operates at 150mA versus the main part's 65mA, with maximum current ratings of 200mA. All parametric equivalents carry ROHS3 Compliant and REACH Unaffected certifications, meeting current regulatory requirements.

Thermal Consideration:

Parametric equivalents exhibit thermal resistance of 25°C/W compared to the main part's 20°C/W. Circuit designs must account for this 5°C/W increase in thermal resistance when thermal management is critical to application performance.

Compliance and Regulatory Status:

All substitute parts meet or exceed the compliance requirements of the original component. ROHS3 Compliant status on all active substitutes aligns with current environmental regulations. REACH Unaffected designation on parametric equivalents confirms regulatory compliance for European markets.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP7WATMS0 be used as a direct replacement for SPMWHT541MP7WATUS0?

A: Yes. SPMWHT541MP7WATMS0 is a direct equivalent from the same LM561B Plus series with identical electrical specifications (2.95V, 65mA test current), mechanical configuration (5630 package, 4-SMD flat leads), and optical properties (4000K, 90 CRI, 120° viewing angle). The direct equivalent is classified as Active, eliminating obsolescence risk.

Q: What are the key differences between the LM561B Plus and LM281B+ series substitutes?

A: Both series maintain identical color temperature (4000K), CRI (90), viewing angle (120°), and package dimensions (5630, 5.00mm x 3.00mm). The LM281B+ series operates at higher test current (150mA versus 65mA) and exhibits higher thermal resistance (25°C/W versus 20°C/W for the main part). Forward voltage in LM281B+ parts ranges from 2.9V to 3.0V, compared to 2.95V in the LM561B Plus.

Q: Are there any circuit design considerations when substituting with LM281B+ parts?

A: Circuit designs must account for the higher test current (150mA) and thermal resistance (25°C/W) of LM281B+ substitutes. Forward voltage tolerance increases slightly (2.9V to 3.0V range). Current-limiting resistor values and thermal management provisions may require adjustment based on specific application requirements.

Q: Do all substitute parts meet RoHS compliance?

A: The direct equivalent SPMWHT541MP7WATMS0 carries ROHS3 Compliant certification. All LM281B+ parametric equivalents are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: What is the inventory availability for substitute parts?

A: SPMWHT541MP7WATMS0 (direct equivalent) has 43274 units in stock. LM281B+ parametric equivalents range from 622 to 1092 units. The main part SPMWHT541MP7WATUS0 has 1149 units available.

Q: Can LM281B+ parts be used in existing designs without PCB modification?

A: Yes. All substitute parts maintain identical package configuration (4-SMD, Flat Leads, 5630), physical dimensions (5.00mm x 3.00mm), and height (0.80mm). PCB footprints and mechanical mounting are compatible. Circuit electrical parameters (forward voltage, current ratings) may require design review for optimal performance.

Q: What is the moisture sensitivity level for substitute parts?

A: The main part SPMWHT541MP7WATUS0 and direct equivalent SPMWHT541MP7WATMS0 both carry MSL 2A (4 Weeks) rating. Moisture sensitivity specifications for LM281B+ parametric equivalents are not provided in the available data.
