OPB695C Equivalent & Substitute Parts

Part Overview

The OPB695C is an optical sensor module with connector manufactured by TT Electronics/Optek Technology, part of the Photologic® series. This component functions as an optical flag module designed for applications requiring optical sensing with integrated connectivity. The OPB695C is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations. Substitute parts must maintain functional equivalence in sensing method, output configuration, and mechanical mounting characteristics while accommodating differences in electrical specifications and product status.

Substitute Part Grouping Explanation

Substitution of the OPB695C is determined by strict equivalence in the following core parameters:

• Sensing Method: Optical Flag (required for functional compatibility)
• Output Configuration: Pull-Up Resistor, Buffer (required for circuit interface compatibility)
• Mounting Type: Snap-In (required for mechanical compatibility)
• Response Time: 30ns (required for timing-critical applications)
• Package / Case: Module, Connector (required for form factor compatibility)
• Current - Supply: 20 mA (required for power budget compatibility)

The OPB695AZ qualifies as a direct substitute based on matching all core parameters. Variations in voltage supply range, operating temperature range, product status, and RoHS compliance do not preclude substitution when the application electrical design and environmental requirements are compatible with the substitute part's specifications.

Engineering Selection Recommendations

The OPB695AZ is the manufacturer-recommended substitute for the obsolete OPB695C. Selection of OPB695AZ is appropriate when:

• The application voltage supply range is compatible with 4.5V ~ 8V operation
• RoHS3 compliance is required or preferred for new designs and procurement
• Active product availability and ongoing manufacturer support are required
• The operating temperature range of -40°C ~ 100°C meets application requirements

The OPB695C remains suitable for legacy system maintenance only when:

• Existing inventory is available and cost-effective
• The application voltage supply range is limited to 14.6V ~ 16V
• RoHS non-compliance is acceptable for the application context
• No regulatory or procurement requirements mandate RoHS compliance

Frequently Asked Questions (FAQ)

Q: Can OPB695AZ directly replace OPB695C in existing designs?

A: Direct replacement is possible only if the application voltage supply falls within the OPB695AZ range of 4.5V ~ 8V. The OPB695C operates at 14.6V ~ 16V. Circuit redesign may be required if the original design depends on the higher voltage range.

Q: What is the primary reason for substitution?

A: The OPB695C is obsolete. The OPB695AZ is the active equivalent from the same manufacturer and series, ensuring continued availability and manufacturer support.

Q: Are there packaging differences between OPB695C and OPB695AZ?

A: Both parts use Module, Connector packaging. The OPB695AZ is supplied in Bulk packaging, while the OPB695C packaging specification is not detailed. Both maintain identical snap-in mounting compatibility.

Q: Does RoHS compliance affect functional performance?

A: RoHS compliance does not affect functional performance. The OPB695AZ achieves ROHS3 compliance while maintaining identical sensing method, output configuration, response time, and current specifications as the OPB695C.

Q: What are the key electrical differences?

A: The primary electrical difference is the voltage supply range. OPB695C operates at 14.6V ~ 16V, while OPB695AZ operates at 4.5V ~ 8V. Current supply (20 mA) and response time (30ns) are identical.

Q: Is the OPB695AZ suitable for high-temperature applications?

A: The OPB695AZ operates across -40°C ~ 100°C. Application-specific temperature requirements must be evaluated against this range.
