OP293C Infrared Emitter - Equivalent & Substitute Parts

Part Overview

The OP293C is an infrared (IR) emitter operating at 890nm wavelength, designed for through-hole mounting in TO-18-2 package configuration. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The OP293C specifications remain functionally relevant for IR emission applications requiring 100mA forward current and 2V typical forward voltage operation across the -40°C to 100°C temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OP293C is determined by strict equivalence across the following electrical and mechanical parameters:

• Wavelength: 890nm (exact match required)
• Forward current rating: 100mA (exact match required)
• Forward voltage: 2V typical (exact match required)
• Viewing angle: 60° (exact match required)
• Package type: TO-18-2 (exact match required)
• Mounting configuration: Through Hole (exact match required)
• Operating temperature range: -40°C ~ 100°C (exact match required)

The OP293B meets all specified parameters and is manufactured by the same supplier (TT Electronics/Optek Technology), providing direct functional equivalence to the obsolete OP293C.

Parameter Comparison

Engineering Selection Recommendations

The OP293B is the direct substitute for the obsolete OP293C. Both components share identical electrical specifications, mechanical packaging, and compliance certifications. The OP293B maintains active product status with TT Electronics/Optek Technology, ensuring continued availability and supply chain reliability. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the OP293B directly replace the OP293C in existing designs? A: Yes. The OP293B is electrically and mechanically equivalent to the OP293C across all specified parameters, including wavelength, forward current, forward voltage, viewing angle, package type, and operating temperature range.

Q: What is the primary reason for substitution? A: The OP293C is classified as obsolete. The OP293B provides an active, equivalent alternative from the same manufacturer.

Q: Are there any compliance differences between the two parts? A: No. Both the OP293C and OP293B are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings.

Q: Does the TO-18-2 package remain the same for both parts? A: Yes. Both components use the TO-18-2 through-hole package configuration, requiring no PCB layout modifications.

Q: What is the availability status of the OP293B? A: The OP293B is an active product with current inventory availability from TT Electronics/Optek Technology.
