OPB819 Equivalent & Substitute Parts

Part Overview

The OPB819 is an optical sensor through-beam phototransistor module manufactured by TT Electronics/Optek Technology. This unamplified sensor operates at a sensing distance of 1.260" (32mm) and is designed for chassis mount applications with pre-wired module packaging. The OPB819 is currently listed as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the OPB819 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for sensing distance, sensing method, output configuration, current rating, voltage rating, operating temperature range, mounting type, and package configuration. The OPB819Z qualifies as a direct substitute based on complete parameter alignment across all these criteria. The primary distinction between the OPB819 and OPB819Z is product status and packaging format: the OPB819 is obsolete with tape/reel packaging, while the OPB819Z is active with bulk packaging.

Parameter Comparison

Engineering Selection Recommendations

The OPB819Z is the direct substitute for the obsolete OPB819. Both parts maintain identical electrical and mechanical specifications, including sensing distance, output configuration, current and voltage ratings, and operating temperature range. The OPB819Z carries active product status with current manufacturing support, whereas the OPB819 is obsolete. Both parts meet ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. Selection of the OPB819Z eliminates obsolescence risk while preserving full functional and electrical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the OPB819Z directly replace the OPB819 in existing applications? A: Yes. The OPB819Z is electrically and mechanically identical to the OPB819 across all specified parameters, including sensing distance, output configuration, current rating, voltage rating, and operating temperature range.

Q: What is the primary difference between OPB819 and OPB819Z? A: The OPB819 is obsolete, while the OPB819Z is active. The OPB819Z is available in bulk packaging, whereas the OPB819 was supplied in tape/reel format. Electrical and mechanical specifications are identical.
