OPA775 LED Engine Equivalent & Substitute Parts

Part Overview

The OPA775 is a white, cool linear light strip LED engine manufactured by TT Electronics/Optek Technology. This component is designed for LED lighting applications requiring a cool color temperature output at 5700K. The OPA775 series remains in active inventory with 911 pieces currently available as new original stock.

Substitute parts are identified to provide alternative sourcing options when the primary OPA775 component is unavailable or when design flexibility permits equivalent component selection. Substitutes maintain compatibility through alignment of critical electrical and mechanical parameters including forward voltage, current ratings, color temperature, and physical form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OPA775 are identified based on the following critical parameters that determine functional equivalence:

• Color Temperature (CCT): Cool white range (5700K–6500K) maintains visual output consistency
• Configuration: Linear light strip form factor ensures mechanical and optical compatibility
• Color: White, cool designation ensures color matching
• Product Type: Chip On Board (COB) and LED engine modules provide equivalent light output architecture
• Availability: Active product status ensures ongoing supply chain viability

The SML-LX12012UWC-WB3 qualifies as a substitute based on alignment across these parameters. While minor variations exist in luminous flux and electrical specifications, both components serve equivalent functional roles in linear light strip applications.

Parameter Comparison

Engineering Selection Recommendations

Both the OPA775 and SML-LX12012UWC-WB3 maintain active product status, ensuring continued availability and manufacturer support. The SML-LX12012UWC-WB3 carries ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for restricted substance control.

Selection between these components should be based on application-specific requirements including forward voltage compatibility, current draw constraints, and color temperature tolerance. The OPA775 operates at 5700K, while the SML-LX12012UWC-WB3 operates at 6500K, representing a 800K difference in correlated color temperature. This difference may be perceptible in applications requiring precise color matching.

The SML-LX12012UWC-WB3 provides documented electrical specifications (12V forward voltage, 320mA test current, 700mA maximum current) and optical performance data (270lm typical luminous flux, 64 lm/W efficiency), enabling direct circuit design integration. The OPA775 specifications should be verified against manufacturer datasheets prior to substitution.

Frequently Asked Questions (FAQ)

Q: Can the SML-LX12012UWC-WB3 directly replace the OPA775 in existing designs?

A: Direct replacement requires verification of forward voltage compatibility, current supply capability, and color temperature tolerance. The 800K difference in CCT (5700K vs. 6500K) may affect visual output. Physical dimensions and mounting interfaces must also be confirmed against application requirements.

Q: What are the key electrical differences between these components?

A: The SML-LX12012UWC-WB3 specifies 12V forward voltage with 320mA test current and 700mA maximum current. The OPA775 electrical specifications are not provided in this reference. Detailed datasheets must be consulted for complete electrical characterization.

Q: Are both components compliant with environmental regulations?

A: The SML-LX12012UWC-WB3 carries ROHS3 compliance and REACH unaffected status. Compliance status for the OPA775 should be verified through the manufacturer's documentation.

Q: What is the significance of the 800K color temperature difference?

A: The OPA775 operates at 5700K (daylight), while the SML-LX12012UWC-WB3 operates at 6500K (cool daylight). This difference may be noticeable in color-critical applications or when components are used in proximity. Application tolerance for color temperature variation should be established prior to substitution.

Q: How do the physical dimensions compare?

A: The SML-LX12012UWC-WB3 dimensions are specified as 120.00mm length × 12.00mm width × 2.80mm height with a flat lens type. OPA775 physical specifications are not provided in this reference and must be obtained from manufacturer documentation.

Q: What is the Moisture Sensitivity Level (MSL) significance?

A: The SML-LX12012UWC-WB3 carries MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. This simplifies logistics and storage requirements compared to higher MSL ratings.
