Substitute Part Grouping Explanation

The OPB695AZ is identified as a manufacturer-recommended substitute for the obsolete OPB697AZ. Substitution eligibility is determined by the following critical parameters:

• Sensing Method: Both components utilize optical flag sensing technology
• Mounting Type: Both employ snap-in mounting configuration
• Electrical Specifications: Identical supply current (20 mA), supply voltage range (4.5V ~ 8V), and response time (30ns)
• Operating Temperature Range: Both rated for -40°C ~ 100°C operation
• Package Configuration: Both feature module with connector packaging
• Compliance Standards: Both maintain ROHS3 compliance and REACH unaffected status
• Series Compatibility: Both belong to the Photologic® product series

The primary distinction between these components is the output configuration: the OPB697AZ features inverted pull-up resistor output, while the OPB695AZ features buffer output. This output configuration difference requires circuit-level evaluation during substitution.

Parameter Comparison

Engineering Selection Recommendations

The OPB695AZ is the active equivalent component for the obsolete OPB697AZ optical sensor module. Both components maintain identical electrical performance specifications, including supply current, voltage range, and response time characteristics. Both components satisfy ROHS3 compliance requirements and REACH regulatory status.

The OPB695AZ is currently in active production status with confirmed inventory availability (1142 pieces), whereas the OPB697AZ is obsolete with limited remaining stock (890 pieces). For new designs and production applications, the OPB695AZ is the appropriate selection. For existing systems currently utilizing the OPB697AZ, the OPB695AZ provides functional equivalence with the noted output configuration difference requiring circuit verification.

Frequently Asked Questions (FAQ)

Q: Can the OPB695AZ directly replace the OPB697AZ in existing applications?

A: The OPB695AZ provides electrical and mechanical equivalence with one critical distinction: output configuration differs between inverted pull-up resistor (OPB697AZ) and buffer output (OPB695AZ). Circuit-level compatibility must be verified based on the specific signal conditioning requirements of the receiving electronics.

Q: What is the significance of the output configuration difference?

A: The OPB697AZ provides inverted logic output through a pull-up resistor configuration, while the OPB695AZ provides buffered output. These configurations produce different signal polarities and drive characteristics. The receiving circuit must be evaluated to determine if signal inversion or buffering requirements are compatible with the substitute component.

Q: Are both components mechanically compatible?

A: Yes. Both the OPB697AZ and OPB695AZ utilize identical snap-in mounting configuration and module connector packaging, ensuring mechanical interchangeability in the physical installation.

Q: What are the electrical operating parameters for both components?

A: Both components operate identically across all specified electrical parameters: 20 mA supply current, 4.5V to 8V supply voltage range, 30ns response time, and -40°C to 100°C operating temperature range.

Q: Are there regulatory or compliance differences between these components?

A: No. Both components maintain identical ROHS3 compliance status and REACH unaffected regulatory status.

Q: Why is the OPB697AZ listed as obsolete?

A: The OPB697AZ has been discontinued by the manufacturer. The OPB695AZ represents the active production equivalent within the Photologic® optical sensor series.
