Engineering Selection Recommendations

Primary Substitute: SPHWH2L3D30CD4RTP3

The SPHWH2L3D30CD4RTP3 is the direct equivalent substitute for the SPHWH2L3D30DD4RTP3. Selection of this substitute is supported by the following engineering factors:

Product Status Advantage: The substitute part carries Active product status, whereas the main part is designated "Not For New Designs." This status difference is significant for long-term supply chain planning and component lifecycle management.

Compliance Enhancement: The substitute meets ROHS3 compliance, representing an upgrade from the main part's RoHS Compliant designation. Both certifications are acceptable for equivalent substitution; the higher standard of the substitute provides additional regulatory assurance.

Electrical and Optical Equivalence: All critical electrical parameters—forward voltage, test current, maximum current, and luminous flux—are identical between the main part and substitute. Lumens per watt efficiency is maintained at 179 lm/W.

Color Rendering Index Variation: The CRI differs by 5 points (75 versus 70). This variation falls within acceptable tolerance for the LH351B series and does not affect functional substitution in standard lighting applications.

Mechanical and Thermal Compatibility: Package dimensions, height, thermal resistance, and mounting characteristics are identical, ensuring direct PCB compatibility and thermal performance equivalence.

Inventory Availability: The substitute part shows higher inventory availability (757 Pcs versus 660 Pcs), supporting procurement reliability.

Frequently Asked Questions (FAQ)

Q: Can SPHWH2L3D30CD4RTP3 be used as a direct replacement for SPHWH2L3D30DD4RTP3 on existing PCBs?

A: Yes. Both parts share identical package dimensions (3535 metric), footprint, height, and mounting type. No PCB redesign or rework is required. The parts are mechanically and electrically interchangeable.

Q: What is the significance of the CRI difference (75 versus 70)?

A: CRI measures color rendering accuracy on a scale of 0–100. The 5-point difference indicates the substitute renders colors slightly less accurately than the main part. For general illumination applications, both values are acceptable. For color-critical applications, the main part's higher CRI may be preferred if available.

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

A: This designation indicates the part is in end-of-life phase. Manufacturers apply this status when transitioning products out of active production. The substitute part's Active status makes it the preferred choice for new designs and ongoing production.

Q: Are the thermal characteristics identical?

A: Yes. Both parts have a thermal resistance of 4°C/W and identical physical dimensions. Thermal performance in circuit applications will be equivalent.

Q: Does the ROHS3 compliance of the substitute affect compatibility?

A: No. ROHS3 is a higher compliance standard than RoHS Compliant. The substitute meets all requirements of the main part's compliance level and exceeds them. This represents an upgrade with no compatibility concerns.

Q: What is the MSL rating, and does it differ between parts?

A: MSL (Moisture Sensitivity Level) 2A (4 Weeks) is identical for both parts. This rating specifies that the component can be exposed to ambient conditions (30°C / 85% RH) for up to 4 weeks before soldering. Storage and handling procedures are the same for both parts.

Q: Are there any electrical parameter differences that affect circuit design?

A: No. Forward voltage (2.8V), test current (350mA), maximum current (1.5A), and luminous flux (175 lm @ 85°C) are identical. Circuit designs require no modification.

Q: What is the viewing angle, and is it the same for both parts?

A: Both parts have a 120° viewing angle, providing wide-angle light distribution suitable for general illumination applications. This parameter is identical between the main part and substitute.
