Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OPA773 are identified based on the following critical parameters that determine functional equivalence:

• Color Classification: White, Cool spectrum
• Configuration Type: Linear Light Strip
• Product Category: LED Lighting COBs Engines Modules
• Color Temperature Range: Cool white (5700K–6500K acceptable range)
• Physical Form Factor: Chip On Board (COB) or equivalent LED engine module

The SML-LX12012UWC-WB3 qualifies as a substitute based on matching color classification (White, Cool), configuration (Linear Light Strip), and product category (LED Lighting COBs). The CCT specification of 6500K for the substitute falls within the cool white spectrum range, providing functional equivalence for applications requiring cool color temperature output.

Engineering Selection Recommendations

OPA773 (Primary Component)

• Recommended for applications where original part specification is required
• 877 pieces available as new original stock
• Established supply chain through TT Electronics / Optek Technology

SML-LX12012UWC-WB3 (Substitute Component)

• Qualifies as functional equivalent based on color classification, configuration type, and cool white spectrum
• Product Status: Active
• RoHS3 Compliant and REACH Unaffected, meeting regulatory requirements
• MSL rating of 1 (Unlimited) indicates minimal moisture sensitivity
• 737 pieces available as new original stock
• Suitable for applications where cool white linear light strip performance is the primary requirement

Selection between these components should be based on design constraints including physical dimensions (120mm L x 12mm W x 2.80mm H for substitute), electrical specifications (12V forward voltage, 320mA test current), and mechanical integration requirements.
