Substitute Part Grouping Explanation

Substitution of the SPMWHT541MP5WARRS4 is determined by strict parametric equivalence across all electrical and mechanical characteristics. All substitute parts maintain identical specifications for color temperature (5000K), luminous flux (34 lm at 65mA), forward voltage (2.95V), maximum current (180mA), viewing angle (120°), package format (4-SMD, Flat Leads, 5630), physical dimensions (5.00mm × 3.00mm × 0.80mm), and CRI (80). The primary differentiator among substitute parts is packaging format (Tape & Reel versus Cut Tape) and product status (Active versus Not For New Designs). Thermal resistance remains consistent at 15°C/W across all parts except SPMWHT541MP5WARSS4, which specifies 14°C/W. All parts comply with RoHS regulations and share identical moisture sensitivity classification (MSL 2A, 4 Weeks).

Engineering Selection Recommendations

All listed substitute parts are parametrically equivalent to SPMWHT541MP5WARRS4 and support direct replacement in existing designs. Selection among substitutes should be based on the following criteria:

Product Status: Parts with Active status (SPMWHT541MP5WAR0S4, SPMWHT541MP5WARKS4, SPMWHT541MP5WARMS4, SPMWHT541MP5WARNS4, SPMWHT541MP5WARSS4) are preferred for new production and long-term supply continuity. The main part SPMWHT541MP5WARRS4 is classified as "Not For New Designs" and should be phased out.

Packaging Format: Selection depends on assembly equipment and supply chain requirements. Tape & Reel (TR) packaging is suitable for high-volume automated pick-and-place operations. Cut Tape (CT) and Digi-Reel® formats provide flexibility for lower-volume or mixed-component assembly. SPMWHT541MP5WAR0S4 offers both Cut Tape and Digi-Reel® options with the highest inventory availability (500,300 pcs).

Compliance Certification: SPMWHT541MP5WAR0S4, SPMWHT541MP5WARKS4, SPMWHT541MP5WARMS4, and SPMWHT541MP5WARSS4 carry ROHS3 Compliant certification, representing the latest regulatory standard. SPMWHT541MP5WARNS4 carries RoHS Compliant status. All parts are REACH Unaffected or comply with REACH requirements.

Thermal Performance: SPMWHT541MP5WARSS4 specifies 14°C/W thermal resistance compared to 15°C/W for all other parts, providing marginally improved thermal dissipation characteristics.

Inventory Availability: SPMWHT541MP5WAR0S4 maintains the highest stock level (500,300 pcs), ensuring supply security for sustained production volumes.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WARRS4 be directly replaced with any of the listed substitute parts?

A: Yes. All substitute parts are parametrically equivalent with identical electrical specifications (5000K color temperature, 34 lm flux, 2.95V forward voltage, 180mA maximum current, 120° viewing angle) and mechanical dimensions (5630 package, 5.00mm × 3.00mm × 0.80mm). Direct substitution is supported without circuit modification.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for high-speed automated assembly. Cut Tape (CT) provides components on cut segments of carrier tape, suitable for lower-volume production or manual assembly. Digi-Reel® is a hybrid format combining cut tape segments on a reel. Selection depends on assembly equipment capability and production volume.

Q: Why is the main part SPMWHT541MP5WARRS4 marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status and Samsung Semiconductor recommends transitioning to active alternatives. Active substitute parts ensure long-term availability and support for ongoing production requirements.

Q: Are there compliance differences between substitute parts?

A: Most substitutes carry ROHS3 Compliant certification (the latest standard), while SPMWHT541MP5WARNS4 carries RoHS Compliant status. Both certifications meet current regulatory requirements. SPMWHT541MP5WARSS4 includes explicit REACH Unaffected status. All parts share identical MSL 2A (4 Weeks) moisture sensitivity classification.

Q: Does thermal resistance variation affect component selection?

A: SPMWHT541MP5WARSS4 specifies 14°C/W thermal resistance compared to 15°C/W for other parts. This 1°C/W difference provides marginally improved thermal dissipation. For applications with stringent thermal management requirements, SPMWHT541MP5WARSS4 may be preferred. For standard applications, the difference is negligible.

Q: Which substitute part offers the best supply security?

A: SPMWHT541MP5WAR0S4 maintains the highest inventory level at 500,300 pcs and offers both Cut Tape and Digi-Reel® packaging options, providing maximum flexibility and supply continuity.

Q: Are all substitute parts from the same manufacturer?

A: Yes. All substitute parts are manufactured by Samsung Semiconductor, Inc., ensuring consistent quality, performance, and reliability across the product family.
