QEE213 Infrared Emitter - Equivalent & Substitute Parts

Part Overview

The QEE213 is an infrared (IR) emitter operating at 940nm wavelength, designed for applications requiring side-view radial mounting. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing production and maintenance requirements. The QEE213 delivers 2mW/sr radiant intensity at 100mA forward current with a 50° viewing angle and operates across the -40°C to 100°C temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the QEE213 is determined by the following critical parameters:

• Wavelength: 940nm (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Side View (exact match required)
• Orientation: Side View (exact match required)
• Operating Temperature Range: -40°C ~ 100°C (exact match required)
• Voltage - Forward (Vf): 1.5V (exact match required)
• Viewing Angle: 50° (exact match required)

The QEE113 meets all critical substitution criteria. While the QEE113 operates at a reduced maximum forward current (50mA versus 100mA), it maintains identical wavelength, package configuration, thermal range, and optical characteristics. The higher radiant intensity specification of the QEE113 (3mW/sr @ 100mA) indicates improved efficiency at its rated current level.

Engineering Selection Recommendations

The QEE113 is the qualified substitute for the QEE213. Selection of the QEE113 provides the following advantages:

• Product Status: The QEE113 maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete QEE213.
• Compliance: The QEE113 is RoHS3 compliant, meeting current regulatory requirements for electronic components.
• Electrical Compatibility: Identical forward voltage (1.5V) and operating temperature range (-40°C ~ 100°C) ensure direct circuit compatibility.
• Optical Characteristics: Matching wavelength (940nm), viewing angle (50°), and orientation (Side View) preserve optical system performance.

The primary design consideration is the reduced maximum forward current rating of the QEE113 (50mA versus 100mA). Circuit designs operating the QEE213 at currents exceeding 50mA require current limiting modifications to accommodate the QEE113.

Frequently Asked Questions (FAQ)

Q: Can the QEE113 directly replace the QEE213 in all applications?

A: Direct replacement is possible when circuit design operates the emitter at forward currents not exceeding 50mA. Applications requiring the full 100mA capability of the QEE213 require circuit modification to limit current to the QEE113 maximum rating.

Q: Are the optical outputs equivalent between QEE213 and QEE113?

A: Both components operate at 940nm wavelength with identical 50° viewing angles and side-view orientation. The QEE113 demonstrates higher radiant intensity efficiency (3mW/sr @ 100mA versus 2mW/sr @ 100mA for the QEE213), indicating improved optical output per unit current at the QEE113 rated current.

Q: What is the impact of the QEE213 obsolete status?

A: Obsolete status indicates discontinued manufacturing and limited remaining inventory. The QEE113 active status ensures continued availability for new designs and production requirements.

Q: Are packaging and mounting configurations identical?

A: Yes. Both components use radial, side-view through-hole packages with identical mechanical and electrical interface specifications.

Q: Does the QEE113 meet current regulatory requirements?

A: The QEE113 is RoHS3 compliant. The QEE213 regulatory status information is not provided in available documentation.
