OPB992T11Z Equivalent & Substitute Parts

Part Overview

The OPB992T11Z is a through-beam optical sensor module manufactured by TT Electronics/Optek Technology, part of the Photologic® series. This component operates as a 0.125" (3.18mm) sensing distance optical sensor with wire leads, designed for chassis mount applications. The part is currently active in production with 992 units in stock. Substitute parts are necessary when the primary part becomes unavailable, when alternative output configurations are required, or when design flexibility demands different mechanical or electrical variants within the same functional category.

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical equivalence to the OPB992T11Z across all specified parameters. Selection among active parts should prioritize inventory availability and supply chain stability. The OPB992P51Z offers the highest inventory level at 69,800 units, followed by OPB992N55Z at 20,299 units, providing superior long-term availability for production applications.

All active substitute parts carry ROHS3 compliance and REACH unaffected status, matching the regulatory posture of the primary part. The OPB982N55Z is marked as obsolete and should not be selected for new designs or long-term production commitments.

Frequently Asked Questions (FAQ)

Q: Can OPB992T11Z be directly replaced with OPB992P51Z? A: Yes. Both parts share identical electrical specifications (4.75V ~ 5.25V supply, 15 mA current, 70ns response time), mechanical configuration (0.125" sensing distance, through-beam method, chassis mount), and package type (module with wire leads). The parts are functionally interchangeable.

Q: What is the difference between OPB992 and OPB982 base product numbers? A: The base product number designates the internal sensor architecture within the Photologic® series. Both OPB992 and OPB982 variants maintain identical output specifications, sensing distance, and electrical parameters as listed in this document. Selection between them does not affect circuit-level compatibility.

Q: Why is OPB982N55Z listed as obsolete? A: OPB982N55Z carries an obsolete product status designation. While remaining inventory exists (812 units), this part should not be specified for new designs. Active alternatives with superior inventory levels are available.

Q: Are all substitute parts ROHS3 compliant? A: All active substitute parts listed carry ROHS3 compliance certification. OPB982N55Z, despite obsolete status, also maintains ROHS3 compliance for existing inventory.

Q: Does the output configuration code (T11Z vs. P51Z vs. N55Z) affect circuit compatibility? A: No. All listed parts maintain identical output configuration specification: Totem Pole, Inverted. The alphanumeric suffix designates internal packaging or manufacturing variant codes that do not alter functional output behavior within the specified electrical parameters.
