Engineering Selection Recommendations

All substitute parts listed are manufactured by Samsung Semiconductor, Inc., and maintain full parametric equivalence to the obsolete SPMWHT541MH7WAV0SB. The primary distinction between the main part and substitutes is product status: the original part is obsolete, while all listed alternatives are active products with current manufacturing support.

Substitute selection should prioritize parts with active product status and adequate inventory levels for production requirements. SPMWHT541MP5WASMS5 and SPMWHT541MP5WASMS4 offer the highest inventory availability at 25,826 and 25,748 pieces respectively. All substitute parts maintain RoHS compliance and identical MSL ratings (2A, 4 Weeks), ensuring compatibility with existing assembly processes and environmental requirements.

The packaging transition from the original part format to Tape & Reel (TR) format across all substitutes reflects current manufacturing standards and improves handling efficiency in automated assembly environments.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAS0S4 be used as a direct replacement for SPMWHT541MH7WAV0SB?

A: Yes. Both parts share identical electrical specifications (2.95V forward voltage, 65mA test current, 180mA maximum current), optical characteristics (120° viewing angle, 80 CRI), and mechanical dimensions (5.00mm x 3.00mm, 0.80mm maximum height). The primary difference is packaging format and product status. SPMWHT541MP5WAS0S4 is an active product supplied in Tape & Reel format.

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

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

Q: Does the Tape & Reel packaging affect component performance?

A: No. Tape & Reel packaging is a delivery and handling format only. It does not affect electrical performance, optical output, or thermal characteristics of the LED component itself. The component specifications remain identical regardless of packaging format.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts maintain RoHS compliance status consistent with the original SPMWHT541MH7WAV0SB specification.

Q: What is the MSL rating and why is it important?

A: All parts carry MSL 2A (4 Weeks) rating. This indicates the component can be exposed to moisture for up to 4 weeks at specified humidity levels before requiring baking. This specification is critical for assembly process planning and storage conditions.

Q: Which substitute part should be selected for new designs?

A: Any of the listed substitute parts are suitable for new designs. Selection should be based on inventory availability, supply chain logistics, and internal part numbering preferences. SPMWHT541MP5WASMS5 and SPMWHT541MP5WASMS4 offer the highest inventory levels for production continuity.
