OPB701 Equivalent & Substitute Parts

Part Overview

The OPB701 is a reflective optical sensor manufactured by TT Electronics/Optek Technology, designed for 0.200" (5.08mm) sensing distance applications with chassis mount configuration. This component features a photodarlington output type and operates across an extended temperature range of -40°C to 100°C. The OPB701 is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure supply chain availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OPB701 is determined by strict equivalence across the following critical parameters:

• Sensing distance: 0.200" (5.08mm)
• Sensing method: Reflective
• Output type: Photodarlington
• Electrical ratings: 15 V collector-emitter breakdown, 100 mA DC forward current
• Mounting configuration: Chassis mount
• Package format: Module, pre-wired
• Operating temperature range: -40°C to 100°C
• Moisture sensitivity: MSL 1

The OPB701Z qualifies as a direct substitute based on identical alignment across all specified parameters. The primary distinction between the OPB701 and OPB701Z is product status and compliance certification, not functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The OPB701Z is the direct equivalent for the obsolete OPB701. Both components share identical electrical specifications, sensing characteristics, and mechanical form factors. The OPB701Z is currently in active production status with improved compliance posture: it meets ROHS3 requirements, whereas the OPB701 is RoHS non-compliant. Both maintain REACH unaffected status and identical export classification (EAR99).

For new designs and production applications, the OPB701Z is the appropriate selection due to its active product status and enhanced regulatory compliance. For field replacements where OPB701 inventory exists, the OPB701Z provides functional and electrical interchangeability without design modification.

Frequently Asked Questions (FAQ)

Q: Can OPB701Z directly replace OPB701 in existing designs?

A: Yes. The OPB701Z is electrically and mechanically identical to the OPB701. Both components feature the same 0.200" (5.08mm) reflective sensing distance, photodarlington output, 15 V collector-emitter breakdown rating, 100 mA maximum forward current, chassis mount configuration, and pre-wired module package. No circuit or mechanical modifications are required.

Q: What is the primary reason to transition from OPB701 to OPB701Z?

A: The OPB701 is classified as obsolete, while the OPB701Z is in active production. The OPB701Z also meets ROHS3 compliance standards, whereas the OPB701 is RoHS non-compliant. For new production and long-term supply assurance, the OPB701Z is the recommended selection.

Q: Are there packaging differences between OPB701 and OPB701Z?

A: Both components are supplied as pre-wired modules in chassis mount configuration. The OPB701Z is available in bulk packaging, while the OPB701 packaging specification is not detailed in the provided data. The functional package format remains identical.

Q: Do both parts operate across the same temperature range?

A: Yes. Both the OPB701 and OPB701Z operate from -40°C to 100°C, ensuring thermal compatibility across equivalent applications.

Q: Are there compliance or certification differences?

A: The OPB701Z meets ROHS3 requirements, while the OPB701 is RoHS non-compliant. Both maintain REACH unaffected status and identical EAR99 export classification. For applications requiring RoHS compliance, the OPB701Z is the appropriate selection.
