OP802SL Equivalent & Substitute Parts

Part Overview

The OP802SL 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 continuity. The OP804SL serves as the direct manufacturer-recommended substitute, offering identical electrical and optical specifications with active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OP802SL is determined by strict equivalence across the following critical parameters:

• Wavelength: 890 nm (infrared detection band)
• Voltage Rating: 30 V collector-emitter breakdown voltage
• Current Specifications: 50 mA maximum collector current and 100 nA maximum dark current
• Power Dissipation: 250 mW maximum
• Package Configuration: TO-206AA (TO-18-3 Metal Can) through-hole mounting
• Orientation: Top view phototransistor design

The OP804SL meets all these criteria identically, establishing it as a direct functional equivalent. Both devices share the same electrical performance envelope, optical response characteristics, and physical form factor, enabling direct substitution without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The OP804SL is the direct substitute for the OP802SL based on complete electrical, optical, and mechanical parameter equivalence. The primary distinction is product status: the OP802SL is obsolete while the OP804SL maintains active production status. Both components carry identical RoHS3 compliance, REACH unaffected designation, and EAR99 export classification, ensuring regulatory continuity in applications requiring the OP802SL.

For new designs or production transitions, the OP804SL should be selected to ensure long-term component availability and supply chain stability. Existing designs using the OP802SL can transition to the OP804SL without modification, as all functional parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the OP804SL directly replace the OP802SL in existing circuits?

A: Yes. The OP804SL is electrically and mechanically identical to the OP802SL across all specified parameters, including voltage ratings, current limits, wavelength response, power dissipation, and package configuration. Direct substitution requires no circuit modifications.

Q: What is the primary reason for substitution?

A: The OP802SL is classified as obsolete. The OP804SL is the manufacturer-recommended active equivalent, ensuring continued availability for production and design support.

Q: Are there any compliance differences between the two parts?

A: No. Both the OP802SL and OP804SL carry identical RoHS3 compliance, REACH unaffected status, and EAR99 export classification. Regulatory requirements remain unchanged with substitution.

Q: Is the TO-206AA package identical between both parts?

A: Yes. Both components use the TO-206AA (TO-18-3 Metal Can) through-hole package with top view orientation. PCB footprints and mounting procedures are identical.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is determined by equivalence in wavelength (890 nm), voltage rating (30 V), collector current (50 mA max), dark current (100 nA max), power dissipation (250 mW), package type (TO-206AA), and operating temperature range (-65°C to 125°C).
