OP803SL Equivalent & Substitute Parts

Part Overview

The OP803SL is a phototransistor optical sensor manufactured by TT Electronics/Optek Technology, designed for 890nm wavelength detection in a TO-206AA (TO-18-3 Metal Can) through-hole package. The device is classified as obsolete, which necessitates identification of active equivalent components for ongoing design support and production requirements. The OP804SL serves as the direct manufacturer-recommended substitute, maintaining identical electrical and optical specifications while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution of the OP803SL with the OP804SL is based on strict equivalence across all provided electrical and mechanical parameters. Both components share identical specifications for wavelength (890nm), maximum collector-emitter breakdown voltage (30V), maximum collector current (50mA), maximum dark current (100nA), maximum power dissipation (250mW), operating temperature range (-65°C to 125°C), and package configuration (TO-206AA, TO-18-3 Metal Can through-hole mounting with top view orientation).

The substitution is valid because:

• Wavelength specification is identical
• Electrical ratings (voltage, current, power) are identical
• Thermal operating range is identical
• Physical package and mounting characteristics are identical
• Both components maintain ROHS3 compliance and REACH unaffected status

Parameter Comparison

Engineering Selection Recommendations

The OP804SL is the direct equivalent for the obsolete OP803SL phototransistor. Selection of the OP804SL is supported by:

• Complete electrical parameter equivalence across all specified ratings
• Identical optical wavelength specification (890nm)
• Identical thermal operating range (-65°C to 125°C)
• Identical mechanical package and mounting configuration
• Active product status ensuring supply chain continuity
• Maintained ROHS3 compliance and REACH unaffected certification status
• Manufacturer-recommended substitution designation

For applications currently using the OP803SL, direct replacement with the OP804SL requires no circuit modifications or design changes. The components are pin-compatible and functionally equivalent across all provided specifications.
