Substitute Part Grouping Explanation

Substitution eligibility for the OPB992T11 is determined by strict equivalence across the following critical parameters:

Sensing Distance: 0.125" (3.18mm)
Sensing Method: Through-Beam
Output Configuration: Totem Pole, Inverted
Mounting Type: Chassis Mount
Current - Supply: 15 mA
Voltage - Supply: 4.75V ~ 5.25V
Response Time: 70ns
Operating Temperature: -40°C ~ 70°C
Package / Case: Module, Wire Leads

All substitute parts listed maintain 100% equivalence across these parameters. The primary distinction between the OPB992T11 and its substitutes is product status (obsolete versus active) and RoHS compliance certification level.

Engineering Selection Recommendations

The OPB992T11 is obsolete and should be replaced with an active equivalent. All listed substitute parts maintain identical electrical and mechanical specifications, ensuring direct functional compatibility.

OPB992T11Z is the direct variant replacement, differing only in packaging designation (bulk) and RoHS3 compliance certification. This part represents the most direct substitution path.

All substitute parts carry ROHS3 Compliant certification, whereas the original OPB992T11 is RoHS non-compliant. This compliance upgrade is applicable across all active alternatives without modification to circuit design or application requirements.

Selection among the substitute parts should be based on inventory availability and internal part numbering conventions within the OPB932, OPB942, OPB982, and OPB992 base product families. All alternatives are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Can OPB992T11 be directly replaced with OPB992T11Z?

A: Yes. OPB992T11Z is the active equivalent of OPB992T11. Both parts share identical electrical specifications, sensing distance, output configuration, and operating parameters. The primary difference is product status (active versus obsolete) and RoHS3 compliance certification.

Q: Are all listed substitute parts electrically interchangeable?

A: Yes. All substitute parts maintain 100% equivalence across sensing distance (0.125"), sensing method (through-beam), output configuration (totem pole, inverted), supply current (15 mA), supply voltage (4.75V ~ 5.25V), response time (70ns), and operating temperature range (-40°C ~ 70°C).

Q: What is the difference between parts in the OPB932, OPB942, OPB982, and OPB992 families?

A: The provided data specifies only parameters common to all parts. Differences between base product families are not defined in the available technical parameters. Selection should be based on internal design requirements and inventory availability.

Q: Does RoHS3 compliance affect circuit design or application requirements?

A: No. RoHS3 compliance is a material composition and manufacturing standard. It does not alter electrical performance, sensing characteristics, or circuit integration requirements. The upgrade from RoHS non-compliant to ROHS3 Compliant status does not require design modifications.

Q: What packaging options are available?

A: All substitute parts are supplied in bulk packaging. The original OPB992T11 packaging designation was not specified in the available data. Confirm packaging requirements with procurement specifications.
