Substitute Part Grouping Explanation

Substitution of SPMWHT541MH7WAVMSB is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

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

Mechanical Equivalence Criteria:

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

Environmental & Compliance Criteria:

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 differentiator is packaging format (Tape & Reel for substitutes versus bulk packaging for the main part) and product status (Active for substitutes versus Obsolete for the main part).

Engineering Selection Recommendations

Primary Selection Criteria:

All substitute parts are classified as Active products, whereas the main part SPMWHT541MH7WAVMSB is Obsolete. This status difference is the primary driver for substitution. All substitute parts maintain full RoHS compliance and identical electrical and mechanical specifications.

Inventory Availability Consideration:

Substitute parts demonstrate significantly higher inventory levels compared to the obsolete main part. SPMWHT541MP5WASMS5 and SPMWHT541MP5WASMS4 each maintain inventory exceeding 25,700 units, providing supply chain stability for production requirements.

Packaging Format:

All substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated assembly operations. The main part uses bulk packaging. This packaging difference does not affect electrical or mechanical performance and is compatible with standard surface mount assembly equipment.

Compliance Status:

All parts maintain identical compliance certifications: RoHS Compliant, ECCN EAR99, and HTSUS 8541.41.0000. Moisture Sensitivity Level 2A (4 Weeks) applies consistently across all parts.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAS0S4 directly replace SPMWHT541MH7WAVMSB in existing designs?

A: Yes. Both parts share identical electrical specifications (2.95V forward voltage, 65mA test current, 180mA maximum current), optical characteristics (120° viewing angle, white color, CRI 80), and mechanical dimensions (5.00mm x 3.00mm, 0.80mm height). The packaging format difference (Tape & Reel versus bulk) does not affect circuit performance.

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

A: All substitute parts maintain identical electrical and mechanical specifications. The part number suffixes (WAS0S4, WAS0S5, WASKS4, WASKS5, WASMS4, WASMS5, WASNS4, WASNS5) indicate different manufacturing lot codes or internal Samsung tracking designations. From an engineering perspective, these parts are functionally equivalent.

Q: Is Tape & Reel packaging compatible with my assembly process?

A: Tape & Reel packaging is the standard format for automated surface mount assembly. If your process currently uses bulk packaging, conversion to Tape & Reel format is standard industry practice and requires no design changes.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts maintain RoHS Compliant status, identical to the main part. Compliance certifications (ECCN EAR99, HTSUS 8541.41.0000) are consistent across all parts.

Q: What is the Moisture Sensitivity Level, and does it affect handling?

A: All parts are classified as MSL 2A (4 Weeks), indicating the component can be stored in standard conditions for up to 4 weeks before soldering. This specification is identical across the main part and all substitutes.

Q: Which substitute part should I select for new production?

A: Selection should be based on inventory availability and internal procurement preferences. SPMWHT541MP5WASMS5 and SPMWHT541MP5WASMS4 offer the highest inventory levels (25,826 and 25,748 units respectively), providing supply chain continuity. All substitute parts are electrically and mechanically equivalent.
