Key Parameters

Substitute Part Grouping Explanation

Substitution of the SDW82F1C-F2G2-HA is determined by the following critical parameters:

Functional Equivalence Criteria:

• Type: Chip On Board (COB) configuration
• Color: White, Warm
• CCT: 2700K color temperature
• Configuration: Square geometry
• CRI: 80 or higher
• Viewing Angle: 120° or greater
• Lens Type: Flat
• RoHS Compliance: ROHS3 Compliant

Electrical Compatibility Considerations:

• Forward Voltage (Vf): Nominal range 35V–37V allows operation within standard driver specifications
• Luminous Flux: Minimum 1440lm at rated current ensures equivalent light output
• Lumens/Watt efficiency: 111 lm/W or higher maintains energy performance
• Current rating: Maximum current of 480mA or higher supports the original operating point

Mechanical Compatibility:

• Square configuration with flat lens type
• Footprint dimensions within acceptable tolerance for direct mounting
• Height variation acceptable if thermal and optical performance are maintained

The CXM-14-27-80-36-AA00-F2-2 meets all substitution criteria and is classified as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CXM-14-27-80-36-AA00-F2-2 is a direct functional substitute for the obsolete SDW82F1C-F2G2-HA based on the following engineering factors:

Product Status & Availability: The substitute part is Active status with 881 units in stock, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Compliance & Certifications: Both parts are ROHS3 Compliant and carry EAR99 ECCN classification. The substitute part carries REACH Unaffected status, providing additional regulatory assurance.

Electrical Performance: The substitute operates at 35V forward voltage versus 37V for the main part, representing a 2V reduction that is within acceptable driver tolerance. At 480mA test current, the substitute delivers 1873lm compared to 1440lm at 350mA for the main part, providing superior light output. Lumens/Watt efficiency is equivalent at 112 lm/W versus 111 lm/W.

Mechanical Compatibility: The substitute footprint is 18.50mm × 18.50mm versus 19.00mm × 19.00mm for the main part, a 0.5mm reduction per side that is negligible for mounting. Height is reduced from 2.30mm to 1.37mm, which may improve thermal management and optical design flexibility.

Moisture Sensitivity: The substitute has MSL 1 (Unlimited) versus MSL 2A (4 Weeks) for the main part, indicating superior moisture resistance and reduced handling constraints during assembly.

Frequently Asked Questions (FAQ)

Q: Can the CXM-14-27-80-36-AA00-F2-2 directly replace the SDW82F1C-F2G2-HA in existing designs?

A: Yes. Both parts are square configuration COBs with identical 2700K color temperature, 80 CRI, and 120° viewing angle. Electrical parameters are compatible within standard driver specifications. Mechanical footprint differences (0.5mm reduction per side, 0.93mm height reduction) are within acceptable tolerances for direct mounting. Forward voltage difference of 2V is within typical driver input range.

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

A: The substitute part offers higher luminous flux (1873lm versus 1440lm), lower forward voltage (35V versus 37V), higher maximum current rating (1A versus 480mA), reduced height (1.37mm versus 2.30mm), and superior moisture sensitivity rating (MSL 1 versus MSL 2A). The substitute is Active status with ongoing availability.

Q: Are there any thermal considerations when substituting?

A: The substitute part has a reduced height of 1.37mm compared to 2.30mm, which may improve thermal dissipation characteristics. Both parts are tested at different temperatures (25°C for main part, 85°C for substitute), reflecting different thermal design points. Thermal interface material and mounting design should be evaluated for the specific application.

Q: What is the significance of the 2-Step MacAdam Ellipse specification on the substitute part?

A: The 2-Step MacAdam Ellipse indicates color consistency tolerance. This specification ensures the substitute part maintains color uniformity within a defined range, supporting consistent visual performance across production batches.

Q: Are both parts RoHS compliant?

A: Yes. Both the SDW82F1C-F2G2-HA and CXM-14-27-80-36-AA00-F2-2 are ROHS3 Compliant. The substitute part additionally carries REACH Unaffected status.

Q: What is the impact of the different packaging specifications?

A: The main part uses standard packaging while the substitute is supplied in Tray packaging. Tray packaging is standard for COB components and does not affect electrical or optical performance. Handling and storage procedures should follow the respective MSL ratings.

Q: Can the substitute part handle higher current than the original?

A: Yes. The substitute part has a maximum current rating of 1A compared to 480mA for the main part. However, operation should remain within the original design current specification (350mA) unless thermal and optical performance are re-evaluated for the specific application.
