Substitute Part Grouping Explanation

Substitute parts for SPMWHT541MP5WATGS5 are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalent (Same Series): SPMWHT541MP5WATMS4 is a direct equivalent within the LM561B Plus series. This part maintains identical electrical specifications: 4000K CCT, 2.95V forward voltage, 65mA test current, 180mA maximum current, 120° viewing angle, and 80 CRI. Physical dimensions, package type (4-SMD, Flat Leads, 5630), and mounting characteristics are identical. The primary difference is product status (Active vs. Not For New Designs) and thermal resistance (16°C/W vs. 20°C/W). This part is the preferred direct replacement.

Parametric Equivalents (Different Series): SPMWH1228FD5W2T0SJ, SPMWH1228FD5W2TKSJ, and SPMWH1228FD5W2TMSJ are LM281B+ series parts that share critical optical and mechanical parameters with the main part: identical 4000K CCT, white neutral color, 120° viewing angle, 80 CRI, 4-SMD flat lead package, 5630 supplier package, and identical physical dimensions (5.00mm x 3.00mm, 0.80mm height). These parts differ in electrical operating point: 2.9V forward voltage and 150mA test current (vs. 2.95V and 65mA). Maximum current rating is 200mA (vs. 180mA). Thermal resistance is 25°C/W (vs. 20°C/W). All three LM281B+ variants are electrically interchangeable within systems designed for their higher current specification.

Substitution eligibility is determined by: color temperature match (4000K), color point (white neutral), viewing angle (120°), CRI (80), package type (4-SMD flat leads 5630), physical dimensions, and forward voltage/current compatibility within the target application circuit.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): SPMWHT541MP5WATMS4 is the recommended substitute for SPMWHT541MP5WATGS5. Both parts are LM561B Plus series with identical electrical and optical specifications. SPMWHT541MP5WATMS4 carries Active product status, ensuring continued availability and supply chain stability. This part features improved thermal resistance (16°C/W vs. 20°C/W), providing superior thermal performance. RoHS3 compliance of SPMWHT541MP5WATMS4 exceeds the RoHS compliance of the main part, meeting current regulatory requirements. Inventory availability is significantly higher (600,200 pcs vs. 955 pcs), supporting production continuity.

For Parametric Substitution (Circuit Redesign Required): SPMWH1228FD5W2T0SJ, SPMWH1228FD5W2TKSJ, and SPMWH1228FD5W2TMSJ are LM281B+ series alternatives suitable for applications where circuit design accommodates higher operating current (150mA test vs. 65mA test). These parts maintain identical optical characteristics (4000K, 120° viewing angle, 80 CRI) and physical form factor (5630 package, 5.00mm x 3.00mm, 0.80mm height). All three LM281B+ variants are Active status with ROHS3 compliance. Selection among the three LM281B+ options is based on inventory availability: SPMWH1228FD5W2TMSJ (1,162 pcs), SPMWH1228FD5W2TKSJ (996 pcs), and SPMWH1228FD5W2T0SJ (845 pcs). Forward voltage difference (2.9V vs. 2.95V) and thermal resistance increase (25°C/W vs. 20°C/W) require circuit validation before implementation.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WATMS4 be used as a direct drop-in replacement for SPMWHT541MP5WATGS5?

A: Yes. SPMWHT541MP5WATMS4 is a direct equivalent within the LM561B Plus series. Electrical specifications (2.95V forward voltage, 65mA test current, 180mA maximum), optical properties (4000K CCT, 120° viewing angle, 80 CRI), and physical dimensions (5630 package, 5.00mm x 3.00mm, 0.80mm height) are identical. No circuit modification is required. The part is pin-compatible and functionally equivalent.

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

A: The LM281B+ series (SPMWH1228FD5W2T0SJ, SPMWH1228FD5W2TKSJ, SPMWH1228FD5W2TMSJ) operates at higher current: 150mA test current and 200mA maximum current, compared to 65mA test and 180mA maximum for LM561B Plus. Forward voltage is slightly lower (2.9V vs. 2.95V). Thermal resistance is higher (25°C/W vs. 20°C/W). Optical characteristics (4000K, 120° viewing angle, 80 CRI) and physical package (5630, 5.00mm x 3.00mm, 0.80mm height) are identical. LM281B+ substitution requires circuit redesign to accommodate the higher current specification.

Q: Are all three LM281B+ variants (SPMWH1228FD5W2T0SJ, SPMWH1228FD5W2TKSJ, SPMWH1228FD5W2TMSJ) electrically identical?

A: Yes. All three LM281B+ parts share identical electrical specifications: 2.9V forward voltage, 150mA test current, 200mA maximum current, 25°C/W thermal resistance. Optical properties (4000K, 120° viewing angle, 80 CRI) and physical dimensions are identical. The parts differ only in packaging designation suffix. Selection is based on inventory availability and supply chain preference.

Q: Why is the main part SPMWHT541MP5WATGS5 marked "Not For New Designs"?

A: "Not For New Designs" status indicates Samsung has transitioned this component to end-of-life phase. The manufacturer recommends using active alternatives for new product development. SPMWHT541MP5WATMS4 (LM561B Plus, Active status) is the recommended path forward for new designs requiring identical electrical and optical specifications.

Q: What is the impact of thermal resistance differences between substitute parts?

A: SPMWHT541MP5WATMS4 has thermal resistance of 16°C/W, compared to 20°C/W for the main part and 25°C/W for LM281B+ variants. Lower thermal resistance indicates better heat dissipation from the LED junction to the PCB. In high-temperature environments or high-current applications, lower thermal resistance improves reliability and extends component life. SPMWHT541MP5WATMS4 provides superior thermal performance compared to the main part.

Q: Are there any compliance differences between the main part and substitutes?

A: The main part SPMWHT541MP5WATGS5 carries RoHS Compliant status. All substitute parts (SPMWHT541MP5WATMS4 and all LM281B+ variants) carry ROHS3 Compliant status, which represents a more current regulatory standard. All parts are EAR99 export classification and HTSUS 8541.41.0000. Moisture sensitivity level is 2A (4 Weeks) across all parts. ROHS3 compliance of substitutes meets or exceeds regulatory requirements of the main part.

Q: Can the LM281B+ parts be used in applications designed for 65mA operation?

A: LM281B+ parts are rated for 150mA test current and 200mA maximum current. They can operate at lower currents, including 65mA, but this represents underutilization of the component's capability. Circuit design should be validated to confirm that forward voltage difference (2.9V vs. 2.95V) and thermal characteristics do not impact system performance. Use of LM281B+ in 65mA applications is technically feasible but not optimal from a component selection perspective.

Q: What is the physical compatibility of the 5630 package across all parts?

A: All parts (main and substitutes) use the 5630 supplier device package with identical physical dimensions: 5.00mm length x 3.00mm width, 0.80mm maximum seated height. All parts feature 4-SMD flat lead configuration. PCB footprint, reflow soldering profile, and pick-and-place equipment compatibility are identical across all parts. No mechanical redesign is required when substituting between these parts.
