Substitute Part Grouping Explanation

Substitution of the SPHWH2L3D30CD4PTP3 is determined by strict electrical and mechanical parameter matching within the LH351B series. The following parameters establish substitution eligibility:

Critical Matching Parameters:

• Series designation (LH351B)
• Forward voltage (Vf = 2.8V typical)
• Test current (350mA)
• Maximum current rating (1.5A)
• Package type (1414 / 3535 Metric)
• Physical dimensions (3.50mm × 3.50mm, 2.06mm max height)
• Thermal resistance (4°C/W)
• Viewing angle (120°)
• Mounting type (Surface Mount)
• CRI (70)

Allowable Variation Parameters:

• Color temperature (CCT): Cool white range (5700K–6500K)
• Luminous flux: Within specified tolerance range (160–190lm @ 85°C)
• Packaging format: Tape & Reel (TR) or standard packaging
• RoHS compliance status: RoHS Compliant or ROHS3 Compliant

The substitute part SPHWH2L3D30CD4QTP3 qualifies as an equivalent because it maintains identical electrical performance, mechanical form factor, and thermal characteristics while operating at 5700K color temperature within the cool white spectrum.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SPHWH2L3D30CD4QTP3

The SPHWH2L3D30CD4QTP3 is a direct electrical and mechanical equivalent to the SPHWH2L3D30CD4PTP3. Both components share identical forward voltage, test current, maximum current rating, luminous flux output, efficiency, CRI, viewing angle, package dimensions, thermal resistance, and mounting characteristics. The only parameter variation is the color temperature specification: 5700K versus 6500K, both within the cool white spectrum.

Compliance Status:

• Main part: RoHS Compliant
• Substitute part: ROHS3 Compliant

Both parts maintain Active product status and identical Moisture Sensitivity Level (MSL 2A, 4 Weeks), ensuring equivalent handling and storage requirements.

Packaging Consideration: The substitute part is supplied in Tape & Reel (TR) format, whereas the main part uses standard packaging. This difference affects procurement and assembly processes but does not alter electrical or thermal performance.

Application Compatibility: The 800K color temperature difference (6500K to 5700K) represents a shift toward warmer tones within the cool white classification. This substitution is suitable for applications where precise color temperature matching is not critical. For applications requiring exact 6500K specification, the main part SPHWH2L3D30CD4PTP3 should be prioritized.

Frequently Asked Questions (FAQ)

Q1: Can SPHWH2L3D30CD4QTP3 be used as a direct replacement for SPHWH2L3D30CD4PTP3 in existing designs?

A: Yes, from an electrical and mechanical standpoint. Both parts operate at identical voltage (2.8V), current (350mA test, 1.5A max), and deliver the same luminous flux (175lm @ 85°C). The 3535 metric package, dimensions, thermal resistance, and viewing angle are identical. The primary consideration is the color temperature difference: 5700K versus 6500K. If the application tolerates this shift within the cool white range, direct substitution is feasible.

Q2: What is the significance of the color temperature difference between 6500K and 5700K?

A: Both temperatures fall within the cool white spectrum. 6500K represents daylight-equivalent white light, while 5700K is slightly warmer. The 800K difference is perceptible in color-critical applications but may be acceptable in general illumination. Applications requiring precise color matching should specify the exact CCT requirement.

Q3: Does the Tape & Reel (TR) packaging of SPHWH2L3D30CD4QTP3 affect electrical performance?

A: No. Packaging format (Tape & Reel versus standard) affects procurement, handling, and assembly logistics but does not alter electrical characteristics, thermal performance, or optical output. Both formats contain identical components.

Q4: Are both parts suitable for current production applications?

A: Yes. Both SPHWH2L3D30CD4PTP3 and SPHWH2L3D30CD4QTP3 maintain Active product status, indicating ongoing manufacturing and support. Both are RoHS compliant (RoHS Compliant and ROHS3 Compliant respectively), meeting environmental and regulatory requirements.

Q5: What are the thermal management implications of using the substitute part?

A: Thermal characteristics are identical. Both parts feature 4°C/W thermal resistance and identical physical dimensions (3.50mm × 3.50mm, 2.06mm max height). Thermal design calculations and PCB layout considerations remain unchanged.

Q6: How do the inventory levels affect part selection?

A: The main part SPHWH2L3D30CD4PTP3 has 908 units in stock, while the substitute SPHWH2L3D30CD4QTP3 has 1287 units available. Inventory availability may influence procurement decisions, particularly for high-volume production runs or time-sensitive projects.

Q7: Are there any handling or storage differences between these parts?

A: No. Both parts share identical Moisture Sensitivity Level (MSL 2A, 4 Weeks), requiring the same storage conditions, handling procedures, and shelf-life management protocols.
