OPB825R Equivalent & Substitute Parts

Part Overview

The OPB825R is an optical sensor module manufactured by TT Electronics/Optek Technology, designed as a through-beam phototransistor sensor with a 0.160" (4.06mm) sensing distance in a slotted chassis mount configuration. The OPB825R is classified as obsolete, making identification of active equivalent parts essential for ongoing production support and component procurement. Substitute parts must maintain identical electrical characteristics and mechanical compatibility to ensure direct replacement capability in existing designs.

Substitute Part Grouping Explanation

Substitute parts for the OPB825R are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is structured as follows:

MFR Recommended Substitute: OPB825 is the manufacturer-recommended direct substitute, sharing identical specifications across all provided parameters including sensing distance, output configuration, current ratings, voltage ratings, operating temperature range, and physical mounting configuration.

Parametric Equivalent: OPB825A is classified as a parametric equivalent, maintaining identical electrical and mechanical specifications while serving as an alternative within the same product family. The OPB825A references OPB825 as its base product number, confirming parametric alignment.

All substitute parts maintain the following critical parameters identical to the OPB825R:

  • Sensing distance: 0.160" (4.06mm)
  • Sensing method: Through-Beam
  • Output configuration: Phototransistor
  • Current ratings: If (Max) 50 mA, Ic (Max) 30 mA
  • Voltage rating: Vce (Max) 30 V
  • Operating temperature: -40°C ~ 85°C
  • Mounting type: Chassis Mount
  • Package type: Module, Slotted
  • Type classification: Unamplified

Engineering Selection Recommendations

OPB825 is the primary substitute for OPB825R applications. As the manufacturer-recommended equivalent with active product status, OPB825 provides full electrical and mechanical compatibility while ensuring ongoing availability and supply chain continuity. Both parts maintain ROHS3 compliance and identical performance specifications.

OPB825A serves as an alternative parametric equivalent, maintaining identical electrical and mechanical characteristics while offering an additional sourcing option. OPB825A is classified as active and ROHS3 compliant, supporting long-term component availability.

Selection between OPB825 and OPB825A should be based on packaging requirements and inventory availability, as both parts are electrically and mechanically interchangeable with the obsolete OPB825R.

Frequently Asked Questions (FAQ)

Q: Can OPB825 directly replace OPB825R in existing designs? A: Yes. OPB825 maintains identical electrical specifications (current ratings, voltage ratings, operating temperature range) and mechanical configuration (chassis mount, slotted module package), enabling direct substitution without design modification.

Q: What is the difference between OPB825 and OPB825A? A: Both parts are parametrically equivalent with identical electrical and mechanical specifications. OPB825A references OPB825 as its base product number. Selection between the two should be based on packaging format and inventory availability.

Q: Why is OPB825R classified as obsolete? A: OPB825R is no longer in active production. OPB825 and OPB825A are the active alternatives that maintain full compatibility with OPB825R applications.

Q: Are there any compliance differences between OPB825R and its substitutes? A: No. All three parts maintain identical RoHS3 compliance status and REACH unaffected classification, ensuring regulatory compatibility across substitution.

Q: What packaging options are available for substitutes? A: OPB825 is available in Bulk packaging. OPB825A is also available in Bulk packaging. Both maintain the Module, Slotted physical configuration required for chassis mount applications.
