Engineering Selection Recommendations

Primary Selection Criteria:

All listed substitute parts are direct parametric equivalents to SPMWHT541MH7WATKSB. Selection among active alternatives should be based on:

Product Status: All substitute parts carry Active product status, ensuring long-term availability and manufacturing support compared to the Obsolete main part.
Inventory Availability: Substitute parts demonstrate significantly higher inventory levels. SPMWHT541MP5WASMS5 (25,826 Pcs), SPMWHT541MP5WASMS4 (25,748 Pcs), and SPMWHT541MP5WAS0S4 (25,612 Pcs) offer optimal stock positions for production planning.
Compliance Certification: All substitute parts maintain RoHS Compliance, ECCN EAR99 classification, and HTSUS 8541.41.0000 coding, ensuring regulatory equivalence for procurement and export documentation.
Packaging Format: All substitutes are supplied in Tape & Reel (TR) format, standard for automated assembly operations. This represents a logistics-level difference with no impact on electrical or mechanical performance.
Moisture Sensitivity: Substitute parts with documented MSL 2A (4 Weeks) rating provide explicit handling specifications for storage and assembly environments.

Substitution Compatibility:

Direct substitution is supported at the circuit board level without design modification. The identical electrical parameters (2.95V Vf, 65mA test current, 180mA maximum current) and mechanical specifications (5630 package, 5.00mm x 3.00mm footprint, 0.80mm height) ensure drop-in compatibility in existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAS0S4 be used as a direct replacement for SPMWHT541MH7WATKSB?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: 2.95V forward voltage, 65mA test current, 180mA maximum current, 120° viewing angle, CRI 80, and 5630 package format with 5.00mm x 3.00mm dimensions. The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. other formats).

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

A: All substitute parts maintain identical electrical and mechanical specifications. Part number variations (WAS0S4, WAS0S5, WASKS4, WASKS5, WASMS4, WASMS5, WASNS4, WASNS5) reflect internal Samsung manufacturing or supply chain designations. These variations do not affect performance, compatibility, or compliance characteristics.

Q: Are there any compatibility issues with existing PCB designs?

A: No. All substitute parts use the identical 4-SMD, Flat Leads package configuration with 5.00mm x 3.00mm footprint and 0.80mm seated height. PCB layouts, solder pad patterns, and assembly processes require no modification.

Q: What is the significance of the Tape & Reel (TR) packaging format?

A: Tape & Reel is the standard supply format for automated surface mount assembly. This format enables high-speed pick-and-place machine compatibility and is the industry standard for production environments. It does not affect the electrical or mechanical properties of the LED component itself.

Q: How should these parts be stored and handled?

A: All substitute parts carry MSL 2A (4 Weeks) moisture sensitivity rating. Components must be stored in controlled humidity environments (typically ≤30% RH) and used within four weeks of package opening. Desiccant storage and baking procedures follow standard IPC-A-610 guidelines for MSL 2A components.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts are RoHS Compliant and carry identical ECCN EAR99 and HTSUS 8541.41.0000 classifications, ensuring regulatory equivalence for procurement, documentation, and export compliance.

Q: Which substitute part offers the best inventory availability?

A: SPMWHT541MP5WASMS5 (25,826 Pcs) and SPMWHT541MP5WASMS4 (25,748 Pcs) provide the highest inventory levels, followed by SPMWHT541MP5WAS0S4 (25,612 Pcs). These options support extended production runs and reduce supply chain risk.
