Key Parameters

Substitute Part Grouping Explanation

Substitution of SPMWHT541MH7WAVKSB is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Forward Voltage (Vf): 2.95V typical
• Test Current: 65mA
• Maximum Current: 180mA
• Color Rendering Index (CRI): 80
• Color: White
• Viewing Angle: 120°

Mechanical Specifications:

• Package Type: 4-SMD, Flat Leads
• Supplier Device Package: 5630
• Physical Dimensions: 0.197" L x 0.118" W (5.00mm x 3.00mm)
• Maximum Seated Height: 0.031" (0.80mm)
• Thermal Resistance: 15°C/W

Environmental & Compliance:

• Moisture Sensitivity Level: 2A (4 Weeks)
• RoHS Compliance: Required
• ECCN: EAR99
• HTSUS: 8541.41.0000

All substitute parts maintain identical specifications across these parameters. The primary distinction between substitute options is packaging format (Tape & Reel) and product status (Active vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation for Direct Substitution:

SPMWHT541MP5WAS0S4 and SPMWHT541MP5WASMS4 are the preferred substitutes for SPMWHT541MH7WAVKSB. Both parts maintain active product status with Samsung Semiconductor, Inc., ensuring long-term availability and supply chain continuity. These alternatives provide the highest inventory levels (25,612 and 25,748 units respectively) and are supplied in Tape & Reel packaging, which is standard for automated assembly operations.

Secondary Alternatives:

SPMWHT541MP5WASMS5 (25,826 units) and SPMWHT541MP5WAS0S5 (25,100 units) are functionally equivalent alternatives with comparable inventory availability. Selection between these options depends on specific procurement and assembly requirements.

Limited Availability Options:

SPMWHT541MP5WASKS4, SPMWHT541MP5WASKS5, SPMWHT541MP5WASNS4, and SPMWHT541MP5WASNS5 are active equivalents with lower inventory levels (ranging from 717 to 1,118 units). These parts are suitable for substitution but should be considered only when primary recommendations are unavailable.

Compliance Assurance:

All substitute parts maintain RoHS compliance, identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications, and equivalent Moisture Sensitivity Level (2A, 4 Weeks). No additional compliance documentation or testing is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAS0S4 be used as a direct replacement for SPMWHT541MH7WAVKSB in existing designs?

A: Yes. SPMWHT541MP5WAS0S4 is a parametric equivalent with 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 primary difference is packaging format (Tape & Reel vs. bulk) and active product status. No circuit modifications are required.

Q: What is the difference between the various substitute part numbers (WAS0S4, WASKS4, WASMS4, WASNS4)?

A: The suffix variations in the part numbers reflect different manufacturing batches or packaging configurations within the same LM561B Plus series. All variants maintain identical electrical and mechanical specifications. Selection should be based on inventory availability and procurement lead times.

Q: Why is SPMWHT541MH7WAVKSB classified as obsolete?

A: The main part number is marked obsolete, indicating Samsung Semiconductor has discontinued this specific variant. The substitute parts listed represent active alternatives from the same product family that maintain full electrical and mechanical compatibility.

Q: Are there any thermal or electrical performance differences between the main part and substitutes?

A: No. All substitute parts maintain identical thermal resistance (15°C/W), forward voltage (2.95V typical), current ratings (65mA test, 180mA maximum), and viewing angle (120°). Performance in thermal and electrical applications is equivalent.

Q: What packaging format should be selected for automated assembly?

A: All substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated pick-and-place assembly equipment. This represents an improvement over the bulk packaging of the obsolete main part number.

Q: Are moisture sensitivity precautions required during handling?

A: Yes. All parts, including substitutes, carry Moisture Sensitivity Level 2A (4 Weeks). Standard ESD and moisture control procedures must be maintained during storage and assembly operations.

Q: Can multiple substitute part numbers be mixed in the same production run?

A: Yes. All substitute parts are parametrically equivalent and interchangeable. However, for traceability and quality control purposes, maintaining consistent part numbers within a single production batch is recommended.
