OP803TXV Equivalent & Substitute Parts

Part Overview

The OP803TXV is a phototransistor optical sensor manufactured by TT Electronics/Optek Technology, designed for 890nm infrared detection applications. This component features a top view orientation in a TO-206AA (TO-18-3 Metal Can) package and is rated for -65°C to 125°C operation. The OP803TXV is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the OP803TXV is determined by strict equivalence across the following critical parameters:

Wavelength matching at 890nm ensures optical compatibility with existing infrared detection circuits. The TO-206AA package and top view orientation maintain mechanical and optical alignment with PCB layouts designed for the original component. Electrical ratings including 30V collector-emitter breakdown voltage, 50mA maximum collector current, and 100nA maximum dark current define the functional operating envelope. The through-hole mounting type and -65°C to 125°C operating temperature range establish compatibility with legacy system designs.

The OP805SL qualifies as a direct substitute based on identical wavelength (890nm), package type (TO-206AA, TO-18-3 Metal Can), orientation (top view), mounting method (through hole), electrical ratings (30V Vce max, 50mA Ic max, 100nA Id max), power dissipation (250mW), and operating temperature range (-65°C to 125°C).

Parameter Comparison

Engineering Selection Recommendations

The OP805SL is the direct substitute for the obsolete OP803TXV. Both components share identical electrical, optical, and mechanical specifications across all critical parameters. The OP805SL maintains active product status with current manufacturing support and improved compliance posture through ROHS3 certification, compared to the non-compliant RoHS status of the OP803TXV. Both components carry REACH Unaffected status and EAR99 export classification. The OP805SL is available in higher inventory quantities (1590 pcs vs. 755 pcs), supporting both replacement and new design applications.

Frequently Asked Questions (FAQ)

Q: Can the OP805SL directly replace the OP803TXV in existing designs?

A: Yes. The OP805SL is electrically and mechanically equivalent to the OP803TXV across all specified parameters, including wavelength (890nm), package type (TO-206AA), electrical ratings (30V, 50mA, 100nA), and operating temperature range (-65°C to 125°C). No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The OP803TXV is obsolete with RoHS non-compliant status, while the OP805SL is an active product with ROHS3 compliance. Functionally and electrically, both components are identical.

Q: Are the packages physically identical?

A: Yes. Both the OP803TXV and OP805SL use the TO-206AA (TO-18-3 Metal Can) package with top view orientation and through-hole mounting. PCB layouts designed for the OP803TXV require no modification for the OP805SL.

Q: Does the OP805SL meet current regulatory requirements?

A: The OP805SL carries ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory standards. The OP803TXV does not meet RoHS requirements.

Q: What is the viewing angle specification for the OP805SL?

A: The viewing angle for the OP805SL is not specified in the provided data. The OP803TXV specifies 24°. Consult the OP805SL datasheet for precise optical characteristics if viewing angle is critical to your application.
