OP225 Infrared Emitter 850nm - Equivalent & Substitute Parts

Part Overview

The OP225 is an infrared (IR) emitter operating at 850nm wavelength, manufactured by TT Electronics/Optek Technology. This component is designed for surface mount applications requiring 50mA maximum forward current and delivers 20mW/sr radiant intensity at 100mA. The OP225 is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OP225 is determined by the following critical parameters:

• Wavelength: Must be 850nm to maintain optical system compatibility
• Viewing Angle: Must be 20° to preserve beam characteristics
• Mounting Type: Must be Surface Mount for PCB integration
• Current Rating: Forward current capability must support circuit design requirements
• Voltage Characteristics: Forward voltage must be compatible with driver circuit specifications
• Operating Temperature Range: Must encompass the application's thermal environment
• Package Compatibility: Physical dimensions and lead configuration must accommodate existing PCB layouts

The MTE8600CP from Marktech Optoelectronics meets the core optical and mechanical requirements for substitution, with allowable variations in current rating and forward voltage within typical circuit design tolerances.

Parameter Comparison

Engineering Selection Recommendations

The MTE8600CP is an active product from Marktech Optoelectronics and represents a viable substitute for the obsolete OP225. Both components share identical wavelength (850nm) and viewing angle (20°) specifications, which are the primary optical parameters determining system compatibility.

The MTE8600CP features a higher maximum forward current rating (80mA versus 50mA) and slightly elevated forward voltage (1.45V versus 1.3V). These differences are within typical design margins for IR emitter applications and do not preclude substitution in circuits designed for the OP225.

Both components maintain RoHS compliance and are classified under the same HTSUS code (8541.41.0000), confirming functional equivalence. The MTE8600CP's active product status ensures ongoing availability and supply chain continuity compared to the OP225's obsolete classification.

Package configuration differs between the two components (1209 versus 2-SMD, No Lead), requiring PCB layout verification prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can the MTE8600CP directly replace the OP225 without circuit modifications?

A: The MTE8600CP shares the critical optical parameters (850nm wavelength, 20° viewing angle) required for functional equivalence. However, the higher forward current rating (80mA) and forward voltage (1.45V) may require driver circuit adjustment. Package configuration differences (1209 versus 2-SMD, No Lead) necessitate PCB layout verification.

Q: What are the key parameters that determine IR emitter substitution?

A: Wavelength, viewing angle, mounting type, and operating temperature range are the primary parameters. For the OP225, the 850nm wavelength and 20° viewing angle are critical for optical system compatibility. Forward current and voltage ratings must be compatible with the driver circuit design.

Q: Does the MTE8600CP meet compliance requirements equivalent to the OP225?

A: Both components are RoHS compliant and share the same HTSUS classification (8541.41.0000). The MTE8600CP maintains active product status, ensuring regulatory compliance and supply chain availability.

Q: What is the impact of the different package configurations?

A: The OP225 uses a 1209 (3224 Metric) package, while the MTE8600CP uses a 2-SMD, No Lead configuration. Physical dimensions and lead placement differ, requiring PCB footprint redesign and layout verification before implementation.

Q: Are there temperature range considerations for substitution?

A: The OP225 operates from -40°C to 85°C, while the MTE8600CP operates from -20°C to 80°C. Applications requiring operation below -20°C or above 80°C may exceed the MTE8600CP's rated range and require alternative components.
