Key Parameters

Substitute Part Grouping Explanation

Substitute part identification for the OP280V is based on the following critical parameters that define functional equivalence:

• Wavelength: 850nm primary specification for IR emitter application
• Current Rating: Maximum forward current capacity (1A for OP280V)
• Voltage Characteristics: Forward voltage typical value (1.95V for OP280V)
• Radiant Intensity: Optical output performance metric (1.05mW/cm² @ 20mA for OP280V)
• Viewing Angle: Beam divergence specification (18° for OP280V)
• Operating Temperature Range: -25°C ~ 85°C (TA)
• Package Type: Surface mount configuration
• Compliance: RoHS3 and REACH status

The identified substitute IR26-21C/L110/TR8 from Everlight Electronics Co Ltd operates at 940nm wavelength with reduced maximum forward current (65mA), different forward voltage (1.2V), and alternative package configuration (1206/3216 Metric). These differences indicate this substitute addresses applications with modified optical and electrical requirements while maintaining surface mount compatibility and equivalent temperature operating range.

Parameter Comparison

Engineering Selection Recommendations

The OP280V is classified as obsolete, making the IR26-21C/L110/TR8 the identified active substitute. Both components maintain RoHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and production continuity.

The IR26-21C/L110/TR8 operates at 940nm wavelength compared to the OP280V's 850nm specification. This wavelength shift represents a fundamental change in application suitability and must be evaluated against system requirements. The substitute component operates at significantly reduced maximum forward current (65mA versus 1A) and lower typical forward voltage (1.2V versus 1.95V), resulting in lower power consumption and heat generation.

Both components share identical operating temperature ranges (-25°C to 85°C) and surface mount mounting types, supporting thermal and assembly compatibility. Package differences (2-PLCC versus 1206/3216 Metric) require PCB layout and footprint modifications.

Frequently Asked Questions (FAQ)

Q: Can the IR26-21C/L110/TR8 directly replace the OP280V in existing designs?

A: Direct replacement requires evaluation of wavelength compatibility. The OP280V operates at 850nm while the IR26-21C/L110/TR8 operates at 940nm. Applications sensitive to specific wavelength performance must confirm functional equivalence. Package differences (2-PLCC versus 1206) necessitate PCB redesign.

Q: What are the key electrical differences between these components?

A: The OP280V supports maximum forward current of 1A at 1.95V typical forward voltage. The IR26-21C/L110/TR8 operates at 65mA maximum forward current with 1.2V typical forward voltage. These differences affect circuit design, current limiting requirements, and power dissipation calculations.

Q: Are both components suitable for the same temperature operating range?

A: Yes. Both the OP280V and IR26-21C/L110/TR8 operate across -25°C to 85°C ambient temperature range, providing equivalent thermal performance specifications.

Q: What packaging considerations apply to substitution?

A: The OP280V uses 2-PLCC surface mount packaging while the IR26-21C/L110/TR8 uses 1206 (3216 Metric) surface mount packaging with bottom entry configuration. PCB footprint, solder reflow profiles, and assembly processes require modification to accommodate the different package geometry.

Q: Do both components meet current regulatory compliance requirements?

A: Yes. Both components are RoHS3 compliant and REACH unaffected, satisfying current regulatory requirements for electronic component manufacturing and distribution.
