Frequently Asked Questions (FAQ)

Q1: Can SPHWHTL3DA0GF4WPN6 be used as a direct replacement for SPHWHTL3DA0GF4W0N6 without circuit redesign?

A: Yes. Both parts are parametrically identical across all electrical, optical, and mechanical specifications. No circuit redesign, PCB layout modification, or firmware adjustment is required. The substitute part operates at identical forward voltage (3V), test current (1.05A), and delivers equivalent luminous output (330 lm @ 85°C) with identical thermal characteristics (2.2°C/W).

Q2: Are there any differences in packaging or moisture sensitivity between these parts?

A: No. Both parts are supplied in Tape & Reel (TR) packaging, use the 1414 (3535 Metric) package designation, and carry identical MSL 2A (4 Weeks) moisture sensitivity ratings. Storage and handling requirements are equivalent.

Q3: What is the difference between the part numbers SPHWHTL3DA0GF4W0N6 and SPHWHTL3DA0GF4WPN6?

A: The part numbers differ only in the suffix designation (0N6 vs. PN6), which typically indicates different manufacturing batches or tape reel configurations from Samsung Semiconductor, Inc. All functional, electrical, and optical parameters remain identical. Both parts share the same base product number (SPHWHTL3) and series (LH351D).

Q4: Will substituting this part affect thermal management in my application?

A: No. Both parts have identical thermal resistance of 2.2°C/W, ensuring equivalent heat dissipation characteristics. Thermal design calculations, heatsink requirements, and thermal interface material specifications remain unchanged.

Q5: Are both parts RoHS compliant?

A: Yes. Both SPHWHTL3DA0GF4W0N6 and SPHWHTL3DA0GF4WPN6 are RoHS compliant and carry identical compliance certifications. No additional regulatory qualification is required for substitution.

Q6: Can I mix these parts in the same production batch?

A: Yes. Since both parts are parametrically identical and manufactured by the same supplier (Samsung Semiconductor, Inc.), they can be used interchangeably within the same production batch without affecting product performance, reliability, or compliance status.

Q7: What is the viewing angle specification, and does it differ between these parts?

A: Both parts have a viewing angle of 128°, ensuring identical light distribution characteristics. This parameter is critical for applications requiring specific beam patterns and does not vary between the main part and substitute.
