Engineering Selection Recommendations

SPMWHT541MP5WAQKS4 is the direct parametric equivalent to SPMWHT541MP5WAQMS4, maintaining identical electrical specifications and 5700K color temperature. Both are packaged in Tape & Reel format. This substitute is suitable for applications requiring the exact 5700K specification with higher inventory availability (16,110 units versus 1,081 units). RoHS compliance is upgraded to ROHS3 standard.

SPMWHT541MP5WAR0S4 and SPMWHT541MP5WARKS4 operate at 5000K color temperature instead of 5700K, representing a 700K shift toward warmer illumination. All electrical parameters remain identical. SPMWHT541MP5WAR0S4 is available in Cut Tape & Digi-Reel® packaging with the highest inventory level (500,300 units). SPMWHT541MP5WARKS4 is available in Cut Tape format (73,313 units). These substitutes are appropriate for applications where color temperature tolerance permits 5000K operation.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541MP5WAQKS4 be used as a direct replacement for SPMWHT541MP5WAQMS4?

A: Yes. SPMWHT541MP5WAQKS4 is a parametric equivalent with identical electrical specifications, color temperature (5700K), and mechanical dimensions. Both are packaged in Tape & Reel format. The only differences are higher inventory availability and upgraded RoHS compliance (ROHS3 versus RoHS Compliant).

Q: What is the difference between the 5700K and 5000K variants?

A: The primary difference is correlated color temperature (CCT). SPMWHT541MP5WAQMS4 and SPMWHT541MP5WAQKS4 operate at 5700K (cooler white light), while SPMWHT541MP5WAR0S4, SPMWHT541MP5WARKS4, and SPMWHT541MP5WARMS4 operate at 5000K (warmer white light). All other electrical and mechanical parameters are identical. Selection depends on application color temperature requirements.

Q: Are the packaging formats interchangeable?

A: Packaging formats differ among substitutes. SPMWHT541MP5WAQMS4 and SPMWHT541MP5WAQKS4 use Tape & Reel (TR). SPMWHT541MP5WAR0S4 uses Cut Tape (CT) & Digi-Reel®. SPMWHT541MP5WARKS4 uses Cut Tape (CT). SPMWHT541MP5WARMS4 uses Tape & Reel (TR). Packaging format compatibility must be verified with assembly equipment specifications before substitution.

Q: Do all substitute parts meet the same compliance standards?

A: SPMWHT541MP5WAQMS4 is RoHS Compliant. All four substitute parts are ROHS3 Compliant, representing an upgraded compliance standard. All parts maintain MSL 2A (4 Weeks) moisture sensitivity level and identical thermal resistance (15°C/W).

Q: What are the mechanical constraints for substitution?

A: All parts share identical mechanical specifications: 5630 package, 4-SMD flat-lead configuration, 5.00 × 3.00 mm dimensions, and 0.80 mm maximum seated height. Substitution does not require PCB layout or assembly process modifications.

Q: Can I substitute based on inventory availability alone?

A: No. Substitution must be based on application requirements for color temperature (5700K or 5000K), packaging format compatibility (Tape & Reel, Cut Tape, or Digi-Reel®), and compliance certifications. Inventory availability is a secondary consideration after confirming electrical and mechanical compatibility.
