Substitute Part Grouping Explanation

Substitution of LED components is determined by strict alignment of electrical and mechanical parameters. For the SPHWH2L3D30ED4TPN3, the critical parameters that define substitutability are:

Electrical Parameters:

• Forward voltage (Vf): 2.8V typical
• Test current: 350mA
• Maximum current: 1.5A
• Color temperature: 4000K neutral white
• Luminous flux range: 150–180lm @ 85°C

Mechanical Parameters:

• Package type: 1414 (3535 Metric)
• Mounting: Surface Mount
• Physical dimensions: 3.50mm × 3.50mm
• Maximum seated height: 2.06mm

Compliance Parameters:

• RoHS compliance status
• Moisture sensitivity level: 2A

The substitute part SPHWH2L3D30CD4TPN3 shares identical electrical specifications (voltage, current, color temperature, flux range, viewing angle) and mechanical specifications (package, dimensions, height, thermal resistance). Both parts are manufactured by Samsung Semiconductor and belong to the LH351B series. The primary difference is packaging format (Tape & Reel vs. standard packaging) and product lifecycle status.

Engineering Selection Recommendations

Primary Part Selection (SPHWH2L3D30ED4TPN3):

The SPHWH2L3D30ED4TPN3 is the recommended choice for new designs and active production. This part maintains Active product status from Samsung Semiconductor, ensuring continued availability and manufacturing support. It carries RoHS Compliant certification and meets current environmental compliance standards. With 951 units in stock inventory, supply continuity is established.

Substitute Part Selection (SPHWH2L3D30CD4TPN3):

The SPHWH2L3D30CD4TPN3 is electrically and mechanically equivalent to the primary part across all critical parameters: forward voltage, test current, maximum current, color temperature, luminous flux, viewing angle, package dimensions, and thermal characteristics. Both parts are manufactured by Samsung Semiconductor within the LH351B series.

The substitute part differs in two aspects:

1. Product Lifecycle Status: The substitute carries "Not For New Designs" status, indicating Samsung has transitioned this part to end-of-life phase. This part is suitable for replacement, repair, or maintenance applications where existing inventory must be sustained, but not recommended for new product development.

2. Color Rendering Index (CRI): The substitute part specifies CRI of 70 compared to the primary part's CRI of 80. This represents a measurable difference in color rendering capability. Applications requiring high color accuracy (CRI ≥ 80) should use the primary part. Applications with standard color rendering requirements can accept the substitute.

3. RoHS Certification Level: The substitute carries ROHS3 Compliant status versus RoHS Compliant for the primary part. Both certifications meet environmental compliance requirements.

4. Packaging Format: The substitute is supplied in Tape & Reel (TR) format, which affects procurement and assembly processes. The primary part uses standard packaging.

Selection Criteria:

• New Designs: Use SPHWH2L3D30ED4TPN3 (Active status, CRI 80)
• Replacement/Maintenance: SPHWH2L3D30CD4TPN3 is electrically compatible if CRI 70 is acceptable and Tape & Reel packaging is compatible with assembly equipment
• High Color Rendering Applications: Use primary part only (CRI 80)
• Standard Color Rendering Applications: Both parts are functionally equivalent

Frequently Asked Questions (FAQ)

Q1: Can SPHWH2L3D30CD4TPN3 be used as a direct replacement for SPHWH2L3D30ED4TPN3 in existing designs?

A: The substitute part is electrically and mechanically compatible. Both parts share identical forward voltage (2.8V), test current (350mA), maximum current (1.5A), color temperature (4000K), luminous flux (165lm @ 85°C), viewing angle (120°), package dimensions (3535 metric), and thermal resistance (4°C/W). The primary difference is Color Rendering Index (CRI 80 vs. CRI 70). If the original design does not require CRI ≥ 80, the substitute is compatible. If CRI 80 is a design requirement, the substitute is not suitable.

Q2: What is the significance of "Not For New Designs" status on the substitute part?

A: This designation indicates that Samsung Semiconductor has discontinued active development and new production of SPHWH2L3D30CD4TPN3. The part remains available from existing inventory but is not recommended for incorporation into new product designs. This status reflects Samsung's product lifecycle management and does not indicate a technical deficiency. The part is suitable for replacement applications, field repairs, and maintenance of existing systems.

Q3: How does the CRI difference (80 vs. 70) affect application suitability?

A: Color Rendering Index (CRI) measures how accurately a light source renders colors compared to natural daylight or incandescent reference. CRI 80 provides good color rendering suitable for general lighting, retail, and residential applications. CRI 70 provides acceptable color rendering for standard industrial and commercial lighting where high color accuracy is not critical. Applications in retail display, photography, art galleries, or color-critical inspection require CRI ≥ 80 and must use the primary part. General area lighting, warehouse, and outdoor applications can use either part.

Q4: Are there packaging compatibility considerations between the two parts?

A: Yes. The primary part (SPHWH2L3D30ED4TPN3) uses standard packaging, while the substitute (SPHWH2L3D30CD4TPN3) is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated pick-and-place assembly equipment. If your assembly process uses manual placement or requires standard packaging format, the primary part is appropriate. If your assembly equipment is configured for Tape & Reel input, the substitute packaging may offer operational advantages. Verify your assembly equipment compatibility before selecting based on packaging format.

Q5: Do both parts meet current environmental compliance requirements?

A: Yes. The primary part carries RoHS Compliant certification. The substitute carries ROHS3 Compliant certification. Both certifications confirm compliance with Restriction of Hazardous Substances directives. ROHS3 represents the current version of the standard. Both parts are acceptable from an environmental compliance perspective. Both parts carry identical Moisture Sensitivity Level (MSL) rating of 2A (4 Weeks), indicating equivalent handling and storage requirements.

Q6: What inventory considerations should influence part selection?

A: The primary part (SPHWH2L3D30ED4TPN3) has 951 units in stock inventory with Active product status, indicating established supply continuity. The substitute part (SPHWH2L3D30CD4TPN3) has 7173 units in stock inventory but carries "Not For New Designs" status, indicating this is existing inventory without ongoing production. For immediate availability of large quantities, the substitute offers higher stock levels. For long-term supply assurance in new designs, the primary part is appropriate.

Q7: Are the thermal characteristics identical between both parts?

A: Yes. Both parts specify thermal resistance of 4°C/W, indicating identical thermal performance. Both parts have maximum seated height of 2.06mm and identical physical dimensions (3.50mm × 3.50mm). Thermal management design considerations are equivalent for both parts.

Q8: Can the substitute part be used in applications requiring maximum current operation?

A: Yes. Both parts specify identical maximum current rating of 1.5A. The substitute part is rated for the same maximum current as the primary part. However, the substitute's lower CRI (70 vs. 80) may affect color quality at high current operation if color rendering is a design consideration.
