Key Parameters

Substitute Part Grouping Explanation

Substitution of SPMWHT541MH7WAQMSB is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Forward Voltage (Vf) Typical: 2.95V
• Current - Test: 65mA
• Current - Maximum: 180mA
• Color Rendering Index (CRI): 80
• Color: White

Mechanical Parameters (Must Match Exactly):

• Package / Case: 4-SMD, Flat Leads
• Supplier Device Package: 5630
• Size / Dimension: 0.197" L x 0.118" W (5.00mm x 3.00mm)
• Height - Seated (Max): 0.031" (0.80mm)
• Viewing Angle: 120°
• Mounting Type: Surface Mount

Thermal & Environmental Parameters (Must Match Exactly):

• Thermal Resistance of Package: 15°C/W
• Moisture Sensitivity Level (MSL): 2A (4 Weeks)

All substitute parts identified maintain these exact specifications. The primary distinction between the main part and substitutes is product status (obsolete versus active) and packaging configuration (bulk versus Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

Primary Substitution Candidates:

The substitute parts SPMWHT541MP5WAS0S4, SPMWHT541MP5WAS0S5, SPMWHT541MP5WASMS4, and SPMWHT541MP5WASMS5 are classified as active products with significantly higher inventory availability (25,100 to 25,826 units). These parts maintain complete electrical and mechanical equivalence to SPMWHT541MH7WAQMSB while offering improved supply chain continuity. All substitute parts are packaged in Tape & Reel (TR) format, which is standard for automated assembly operations.

Compliance Considerations:

All substitute parts share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications with the original part, ensuring consistent export control and tariff treatment. Substitute parts with specified Moisture Sensitivity Level (MSL) 2A (4 Weeks) maintain the same handling requirements as the original component.

Packaging Transition:

The transition from bulk packaging (SPMWHT541MH7WAQMSB) to Tape & Reel packaging (all substitutes) is standard in LED component procurement. Tape & Reel format provides improved handling efficiency in automated pick-and-place assembly processes and reduces component damage during manufacturing.

Inventory Optimization:

For applications requiring immediate availability, SPMWHT541MP5WASMS5 (25,826 units) and SPMWHT541MP5WASMS4 (25,748 units) offer the highest stock levels. For lower-volume requirements, SPMWHT541MP5WASKS4 (1,012 units) and SPMWHT541MP5WASNS4 (1,118 units) provide alternative sourcing options.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAS0S4 be used as a direct replacement for SPMWHT541MH7WAQMSB in existing designs?

A: Yes. SPMWHT541MP5WAS0S4 maintains identical electrical specifications (2.95V forward voltage, 65mA test current, 180mA maximum current), mechanical dimensions (5.00mm x 3.00mm, 0.80mm height), and thermal characteristics (15°C/W). The only difference is packaging format (Tape & Reel versus bulk) and active product status. No circuit modifications are required.

Q: What is the difference between the various MP5 substitute part numbers?

A: The substitute parts differ only in packaging configuration and moisture sensitivity documentation. All MP5 variants (WAS0S4, WAS0S5, WASKS4, WASKS5, WASMS4, WASMS5, WASNS4, WASNS5) maintain identical electrical and mechanical specifications. The suffix variations indicate different packaging reels or moisture sensitivity level documentation. Selection should be based on assembly equipment compatibility and inventory availability.

Q: Are all substitute parts RoHS compliant?

A: The original part SPMWHT541MH7WAQMSB is explicitly documented as RoHS Compliant. While RoHS compliance status is not specified in the provided data for substitute parts, all parts share identical ECCN and HTSUS classifications, indicating equivalent regulatory treatment. Confirmation of RoHS compliance for specific substitute parts should be obtained from Samsung Semiconductor documentation.

Q: What is the significance of the MSL (Moisture Sensitivity Level) 2A (4 Weeks) specification?

A: MSL 2A (4 Weeks) indicates that the component can be stored in standard conditions for up to 4 weeks after the moisture barrier bag is opened. After this period, the component must be baked according to IPC-A-610 standards before soldering. Substitute parts with specified MSL 2A (4 Weeks) require identical handling procedures as the original component. Parts without specified MSL should be treated according to standard IPC guidelines.

Q: Can substitute parts with different MSL specifications be mixed in production?

A: Parts with specified MSL 2A (4 Weeks) and parts without specified MSL documentation should not be mixed without confirming equivalent moisture sensitivity requirements. For production consistency, select substitute parts with documented MSL specifications matching the original component (SPMWHT541MP5WAS0S4, SPMWHT541MP5WAS0S5, SPMWHT541MP5WASMS4, SPMWHT541MP5WASMS5).

Q: What is the viewing angle specification and how does it affect application suitability?

A: The 120° viewing angle indicates the half-angle at which luminous intensity drops to 50% of the peak value. All parts, including substitutes, maintain this 120° specification, ensuring identical light distribution characteristics in optical designs. No optical redesign is required when substituting parts.

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

A: No. All parts maintain identical thermal resistance of 15°C/W. Thermal management calculations and PCB layout considerations remain unchanged when substituting SPMWHT541MH7WAQMSB with any of the listed MP5 variants.
