Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SPHWH2L3D30CD4RTK3 is determined by the following critical parameters:

• Color Temperature: 5000K cool white (exact match required)
• Package Footprint: 3535 metric (1414) surface mount (exact match required)
• Forward Voltage Range: 2.72V to 2.8V (compatible operating range)
• Test Current: 350mA nominal (standard test condition)
• Maximum Current Rating: 1.5A (must not be exceeded)
• CRI: 70 (color rendering index match)
• Thermal Resistance: 4°C/W (thermal management compatibility)

The CreeLED XPGBWT-01-0000-00KE3 (XLamp XP-G2 series) meets all substitution criteria within these electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The XPGBWT-01-0000-00KE3 is a direct functional substitute for the SPHWH2L3D30CD4RTK3 based on the following engineering criteria:

Both components are RoHS Compliant and share identical thermal resistance specifications (4°C/W), ensuring equivalent thermal management in circuit designs. The CreeLED XLamp XP-G2 maintains Active product status, providing ongoing manufacturer support and supply chain availability, whereas the Samsung LH351B is classified as Not For New Designs.

Electrical compatibility is established through matching test current (350mA), maximum current rating (1.5A), and CRI (70). Forward voltage differs by 0.08V (2.8V vs 2.72V), which falls within acceptable operating tolerances for LED driver circuits designed for the original component.

The substitute part delivers higher luminous efficacy (168 lm/W vs 148 lm/W) and greater luminous flux output (160lm vs 145lm at 85°C), representing improved performance characteristics. Viewing angle differs by 5° (115° vs 120°), and physical dimensions vary slightly (3.45mm vs 3.50mm footprint; 2.39mm vs 2.06mm height), requiring verification against specific PCB layout and optical design constraints.

Frequently Asked Questions (FAQ)

Q: Can the XPGBWT-01-0000-00KE3 be used as a direct drop-in replacement for the SPHWH2L3D30CD4RTK3?

A: Electrical substitution is valid based on matching color temperature (5000K), test current (350mA), maximum current (1.5A), and thermal resistance (4°C/W). However, physical dimensions differ: the CreeLED part is 0.33mm shorter in height (2.39mm vs 2.06mm) and 0.05mm smaller in footprint (3.45mm vs 3.50mm). PCB layout and mechanical clearance must be verified before implementation.

Q: What are the key differences in performance between these two LEDs?

A: The CreeLED XLamp XP-G2 provides superior luminous efficacy (168 lm/W vs 148 lm/W) and higher flux output (160lm vs 145lm at 85°C). The viewing angle is narrower (115° vs 120°), which may affect light distribution in wide-angle applications. Forward voltage is 0.08V lower (2.72V vs 2.8V), requiring minor driver circuit adjustment if voltage regulation is critical.

Q: Are both parts RoHS compliant?

A: Yes, both the SPHWH2L3D30CD4RTK3 and XPGBWT-01-0000-00KE3 are RoHS Compliant. The CreeLED part additionally carries REACH Unaffected status.

Q: Why is the Samsung LH351B marked as Not For New Designs?

A: Product status indicates Samsung has discontinued active development and marketing of this series. The CreeLED XLamp XP-G2 maintains Active status, ensuring continued availability and manufacturer technical support for new applications and production runs.

Q: What should be considered when switching from the Samsung to the CreeLED part?

A: Verify PCB layout compatibility with the 0.33mm height difference and 0.05mm footprint reduction. Confirm LED driver circuit can operate at 2.72V forward voltage. Assess whether the 5° narrower viewing angle (115° vs 120°) meets optical design requirements. Test thermal performance in the target application, as both parts share identical 4°C/W thermal resistance but may have different thermal interface characteristics.
