Parameter Comparison

Engineering Selection Recommendations

SPMWHT541ML5XATKS0 is the primary part specification. This component is Active status and RoHS Compliant, meeting regulatory requirements for general illumination applications.

SPMWHT541ML5XATMS0 is a parametric equivalent substitute. Both parts are manufactured by Samsung Semiconductor, Inc., belong to the LM561C series, and share identical mechanical, optical, and thermal characteristics. The forward voltage difference of +0.05V (2.8V vs. 2.75V) and lumens/watt difference of −3 lm/W fall within normal manufacturing tolerance bands for this LED series and do not affect functional compatibility in standard circuit designs.

Selection between these parts may be based on:

• Inventory availability (SPMWHT541ML5XATMS0 has higher stock: 33,730 pcs vs. 769 pcs)
• Packaging format (both supplied in Tape & Reel)
• Lead time requirements
• Cost considerations

Both parts are RoHS Compliant and carry identical MSL ratings (2A, 4 Weeks), ensuring equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can SPMWHT541ML5XATMS0 be used as a direct replacement for SPMWHT541ML5XATKS0?

A: Yes. Both parts are Samsung LM561C series LEDs with identical color temperature (4000K), CRI (80), package type (5630 4-SMD), and mechanical dimensions (5.00mm × 3.00mm). The forward voltage difference of 0.05V is within normal series tolerance and does not affect circuit compatibility.

Q: What is the significance of the forward voltage difference (2.75V vs. 2.8V)?

A: The 0.05V difference represents normal manufacturing variation within the LM561C series specification. Both values fall within the typical operating range for this LED series. Circuit designs using current-limiting resistors or constant-current drivers will accommodate this variation without performance degradation.

Q: Are the optical characteristics identical between these parts?

A: Yes. Both parts deliver 34lm at 65mA test current (32–36lm tolerance band), operate at 4000K neutral white, and maintain 80 CRI. The lumens/watt difference (190 vs. 187 lm/W) is within series tolerance and does not affect perceived brightness or color quality in application.

Q: Do these parts have the same thermal characteristics?

A: Yes. Both parts have identical thermal resistance of 12°C/W and the same maximum height of 0.80mm when seated. Thermal management considerations are equivalent.

Q: Are there any differences in compliance or handling requirements?

A: No. Both parts are RoHS Compliant and carry identical Moisture Sensitivity Level (MSL) ratings of 2A (4 Weeks). Storage, handling, and soldering requirements are identical.

Q: What is the primary reason to consider the substitute part?

A: Inventory availability. SPMWHT541ML5XATMS0 has significantly higher stock (33,730 pcs) compared to SPMWHT541ML5XATKS0 (769 pcs), making it suitable for high-volume production or urgent fulfillment scenarios where parametric equivalence is confirmed.

Q: Can these parts be mixed in the same production batch?

A: Yes. Both parts meet identical electrical, optical, mechanical, and compliance specifications. Mixing is permissible from an engineering standpoint, though manufacturing process controls should document any intentional substitution.
