1N6265 Infrared Emitter 940nm Equivalent & Substitute Parts

Part Overview

The 1N6265 is an infrared (IR) emitter operating at 940nm wavelength, designed for through-hole mounting in TO-46-2 metal can packaging. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The 1N6265 delivers 100mA maximum forward current with a typical forward voltage of 1.7V and an 80° viewing angle, suitable for IR transmission applications requiring metal can construction.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1N6265 is determined by the following critical parameters:

• Wavelength: 940nm (exact match required for IR transmission compatibility)
• Current - DC Forward (If) (Max): 100mA (electrical rating must be maintained or exceeded)
• Mounting Type: Through Hole (mechanical compatibility with PCB assembly)
• Type: Infrared (IR) Emitter (functional category)

The QED234 qualifies as a substitute based on matching wavelength (940nm), identical maximum forward current (100mA), and through-hole mounting compatibility. Variations in forward voltage (1.6V max vs. 1.7V typ), viewing angle (40° vs. 80°), and package form factor (radial 5mm vs. TO-46-2 metal can) are secondary considerations dependent on circuit design requirements and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The QED234 is an active product from onsemi and serves as the primary substitute for the obsolete 1N6265. Both components maintain identical wavelength (940nm) and maximum forward current (100mA) specifications, ensuring functional compatibility in IR transmission circuits.

Selection between these parts depends on:

• Package Compatibility: The 1N6265 uses TO-46-2 metal can packaging, while the QED234 uses radial 5mm form factor. PCB layout and mechanical mounting requirements determine which package is suitable.
• Viewing Angle: The 1N6265 provides 80° viewing angle versus the QED234's 40° angle. Application-specific beam width requirements dictate the appropriate choice.
• Operating Temperature Range: The 1N6265 operates from -65°C to 125°C, while the QED234 operates from -40°C to 100°C. Environmental specifications must align with application requirements.
• Forward Voltage: The QED234 specifies 1.6V maximum versus the 1N6265's 1.7V typical. Circuit design must accommodate this voltage differential.
• Compliance Status: The QED234 is RoHS3 compliant and active in production, providing long-term availability assurance compared to the obsolete 1N6265.

Frequently Asked Questions (FAQ)

Q: Can the QED234 directly replace the 1N6265 in existing designs?

A: Direct replacement depends on mechanical and optical requirements. Both components share identical wavelength (940nm) and current ratings (100mA). However, the QED234's different package form factor (radial 5mm vs. TO-46-2 metal can) and narrower viewing angle (40° vs. 80°) require verification against PCB layout and optical beam width specifications.

Q: What are the key differences between these two parts?

A: The primary differences are package type, viewing angle, operating temperature range, and product status. The 1N6265 is obsolete with TO-46-2 metal can packaging and 80° viewing angle. The QED234 is active with radial 5mm packaging and 40° viewing angle. The QED234 also has a narrower operating temperature range (-40°C to 100°C vs. -65°C to 125°C).

Q: Are there compliance or regulatory differences?

A: Both components are REACH Unaffected and classified as EAR99. The QED234 is RoHS3 compliant, while the 1N6265 does not specify RoHS status. For new designs subject to RoHS requirements, the QED234 is the appropriate choice.

Q: What should I verify before substituting the QED234 for the 1N6265?

A: Verify PCB layout compatibility with the radial 5mm package, confirm that the 40° viewing angle meets optical requirements, and ensure the operating temperature range (-40°C to 100°C) covers your application environment. Additionally, validate that the forward voltage specification (1.6V max) is acceptable for your circuit design.

Q: Is the QED234 suitable for high-temperature applications?

A: The QED234 operates to a maximum of 100°C, which is lower than the 1N6265's 125°C maximum. For applications requiring operation above 100°C, the 1N6265's extended temperature range may be necessary, though availability as an obsolete part should be confirmed with your supplier.
