QVE00112 Equivalent & Substitute Parts

Part Overview

The QVE00112 is an optical sensor manufactured by onsemi, part of the OPTOLOGIC® series. It is a through-beam optical sensor with a 0.118" (3mm) sensing distance, featuring NPN open collector inverted output configuration and wire lead connectivity for chassis mount applications. The product is currently obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the QVE00112 is based on the following critical parameters that must align for functional equivalence:

• Sensing Method: Through-beam operation required
• Output Configuration: NPN open collector inverted output
• Sensing Distance: Nominal range 0.118" to 0.125" (3mm to 3.18mm)
• Supply Voltage: Operating range overlap between 4.5V–5.5V and alternative supply specifications
• Response Time: 70ns specification maintained
• Mounting Type: Chassis mount with wire leads
• Package Configuration: Module with wire lead termination

The OPB993L55Z from TT Electronics/Optek Technology meets these substitution criteria with minor parameter variations within acceptable engineering tolerances.

Engineering Selection Recommendations

OPB993L55Z as Primary Substitute

The OPB993L55Z is the designated substitute for the obsolete QVE00112. Selection of this alternative is based on:

• Functional Equivalence: Identical sensing method, output configuration, response time, and package type
• Active Product Status: OPB993L55Z maintains active production status, ensuring long-term availability
• Compliance: RoHS3 compliant; REACH unaffected status maintained
• Supply Voltage Compatibility: Operating range 4.75V–5.25V overlaps with the QVE00112 specification window, suitable for standard 5V supply systems
• Thermal Consideration: Operating temperature maximum of 70°C is adequate for most industrial applications; systems requiring operation above 70°C require thermal analysis

Parameter Deviations Requiring System Evaluation

• Sensing distance variation of 0.007" (0.18mm) may require mechanical adjustment in optical path alignment
• Supply current increase from 12 mA to 15 mA requires verification that power supply capacity is sufficient
• Upper operating temperature limit reduction from 85°C to 70°C necessitates confirmation that application thermal environment does not exceed this threshold

Frequently Asked Questions (FAQ)

Q: Can the OPB993L55Z directly replace the QVE00112 without modification?

A: The OPB993L55Z is functionally equivalent for standard 5V through-beam sensing applications. Mechanical mounting and optical alignment may require adjustment due to the 0.007" sensing distance variation. Verify that system power supply capacity accommodates the 15 mA current requirement and that operating temperature does not exceed 70°C.

Q: What is the significance of the sensing distance difference between 3mm and 3.18mm?

A: The 0.118" (3mm) and 0.125" (3.18mm) specifications represent the physical gap between emitter and receiver in the through-beam configuration. This 0.007" (0.18mm) difference may require minor mechanical repositioning of the sensor in the optical path. Verify that the application's mechanical tolerance accommodates this variation.

Q: Are the supply voltage ranges compatible?

A: The QVE00112 operates at 4.5V–5.5V, while the OPB993L55Z operates at 4.75V–5.25V. The overlapping range is 4.75V–5.25V. Systems operating at the extremes of the QVE00112 specification (below 4.75V or above 5.25V) require alternative solutions or voltage regulation.

Q: What is the impact of the 3 mA current increase?

A: The OPB993L55Z draws 15 mA compared to the QVE00112's 12 mA. Verify that the system power supply has sufficient capacity for this additional 3 mA load. This is typically not a constraint in standard industrial applications but should be confirmed in current-limited or battery-powered systems.

Q: Is the OPB993L55Z suitable for high-temperature applications?

A: The OPB993L55Z is rated for operation up to 70°C, compared to the QVE00112's 85°C maximum. Applications requiring operation above 70°C require alternative component selection or thermal management measures.

Q: Are there compliance or certification differences?

A: The OPB993L55Z is RoHS3 compliant and REACH unaffected. Both parts share identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, ensuring regulatory consistency for procurement and export purposes.
