• Height: 1.50 mm
• Light Emitting Surface (LES) Diameter: 14.50 mm
• Lens Type: Flat

Optical Specifications:

• Color: White, Cool
• CCT (Correlated Color Temperature): 6500K with 3-Step MacAdam Ellipse tolerance
• CRI (Color Rendering Index): 80
• Viewing Angle: 115°

Electrical Specifications:

• Test Current: 540 mA
• Test Temperature: 85°C
• Forward Voltage (Vf) Typical: 34.6 V (±tolerance range)
• Maximum Current: 1.38 A

Compliance & Environmental:

• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level (MSL): 2A (4 Weeks)

Engineering Selection Recommendations

Primary Substitute: SPHWHAHDNF25YZP3DB

The SPHWHAHDNF25YZP3DB is the designated substitute for the obsolete SPHWHAHDNF25YZP3J5. This substitution is supported by the following engineering criteria:

Mechanical Compatibility: Both parts share identical physical dimensions (19.00 mm × 19.00 mm × 1.50 mm height), square configuration, flat lens type, and 14.50 mm LES diameter. Direct mechanical interchangeability is confirmed.

Optical Specifications: Both parts maintain identical color (White, Cool), CCT (6500K with 3-Step MacAdam Ellipse), CRI (80), and viewing angle (115°). Optical performance characteristics are equivalent.

Electrical Parameters: Both parts operate at identical test conditions (540 mA, 85°C). The substitute exhibits a typical forward voltage of 34.0 V compared to 34.6 V in the main part, representing a −0.6 V difference within normal tolerance ranges for LED COB devices. The substitute's maximum current rating of 1.08 A is lower than the main part's 1.38 A, which does not impact substitution validity as it represents a more conservative operating envelope.

Performance Enhancement: The substitute demonstrates improved luminous flux (2966 lm vs. 2726 lm, +8.8%) and luminous efficacy (162 lm/W vs. 146 lm/W, +11.0%) at identical test conditions, indicating advancement in LED COB technology generation.

Regulatory Compliance: Both parts maintain RoHS Compliance status and identical Moisture Sensitivity Level (2A, 4 Weeks), ensuring equivalent environmental and handling requirements.

Product Status: The substitute is classified as Active, ensuring ongoing availability and supply chain continuity compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q1: Can the SPHWHAHDNF25YZP3DB directly replace the SPHWHAHDNF25YZP3J5 in existing designs?

A: Yes. Both parts share identical mechanical dimensions, optical specifications (color, CCT, CRI, viewing angle), electrical test conditions, and compliance certifications. Direct substitution is supported without design modification.

Q2: What are the key differences between these two parts?

A: The primary differences are product status (obsolete vs. active), series designation (LC019D vs. COB D Gen2 Plus), and performance metrics. The substitute delivers higher luminous flux (+8.8%) and improved luminous efficacy (+11.0%) at identical test conditions. Forward voltage is slightly lower (34.0 V vs. 34.6 V), and maximum current rating is lower (1.08 A vs. 1.38 A).

Q3: Are there any electrical compatibility concerns when substituting?

A: No. Both parts operate at identical test current (540 mA) and temperature (85°C). The substitute's lower maximum current rating (1.08 A vs. 1.38 A) does not create compatibility issues; it represents a more conservative operating specification. Forward voltage difference (−0.6 V) is within normal tolerance for LED COB devices and does not affect circuit compatibility.

Q4: Do the parts have identical physical form factors?

A: Yes. Both parts are square configuration COBs with dimensions of 19.00 mm × 19.00 mm × 1.50 mm height, 14.50 mm LES diameter, and flat lens type. Mechanical interchangeability is confirmed.

Q5: Are moisture sensitivity and handling requirements the same?

A: Yes. Both parts carry identical Moisture Sensitivity Level (MSL) rating of 2A (4 Weeks), requiring identical storage, handling, and reflow procedures.

Q6: Does the substitute meet the same regulatory compliance standards?

A: Yes. Both parts are RoHS Compliant with identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q7: Why does the substitute have a lower maximum current rating?

A: The lower maximum current rating (1.08 A vs. 1.38 A) in the substitute reflects design improvements in the COB D Gen2 Plus generation, allowing efficient operation within a more conservative current envelope while delivering superior luminous flux and efficacy at the standard test current of 540 mA.

Q8: Is the improved luminous flux in the substitute a concern for thermal management?

A: No. The improved luminous flux (+8.8%) and efficacy (+11.0%) at identical test conditions (540 mA, 85°C) indicate more efficient light generation, which typically results in lower thermal output per lumen. Thermal management requirements should be equivalent or improved compared to the main part.

Q9: What is the availability status of each part?

A: The SPHWHAHDNF25YZP3J5 (main part) is classified as Obsolete with 746 pcs in stock. The SPHWHAHDNF25YZP3DB (substitute) is classified as Active with 954 pcs in stock, ensuring reliable long-term supply chain availability.

Q10: Are there any packaging differences between the parts?

A: The main part packaging is listed as "−" (unspecified), while the substitute is packaged in Tray format. Confirm packaging requirements with your procurement specifications.
