Substitute Part Grouping Explanation

Substitution of the OPB704G is determined by strict equivalence across the following critical parameters:

• Sensing distance: 0.149" (3.8mm)
• Sensing method: Reflective
• Output type: Phototransistor
• Electrical ratings: Voltage - Collector Emitter Breakdown (Max) 30 V, Current - Collector (Ic) (Max) 6 mA, Current - DC Forward (If) (Max) 40 mA
• Compliance certifications: ROHS3 Compliant, REACH Unaffected

The OPB704GWZ qualifies as a direct substitute based on identical electrical performance parameters and sensing characteristics. The primary distinction lies in mounting configuration and product status, with the OPB704GWZ offered in an active product status with pre-wired chassis mount packaging.

Parameter Comparison

Engineering Selection Recommendations

The OPB704GWZ serves as the active equivalent for the obsolete OPB704G. Both components maintain identical electrical performance specifications and sensing characteristics, ensuring functional compatibility in reflective optical sensing applications. The OPB704GWZ carries active product status with current manufacturing support, addressing the obsolescence of the original OPB704G.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current production environments. The transition from through-hole to chassis mount configuration and the addition of pre-wired packaging in the OPB704GWZ may require mechanical redesign considerations in the application assembly.

Frequently Asked Questions (FAQ)

Q: Can the OPB704GWZ directly replace the OPB704G in existing designs?

A: Electrical and sensing performance are identical. Mechanical integration requires evaluation due to differences in mounting type (through hole versus chassis mount) and packaging configuration (standard module versus pre-wired module).

Q: What are the key parameters that define substitution eligibility?

A: Sensing distance (0.149"), sensing method (reflective), output type (phototransistor), and electrical ratings (30 V max collector-emitter breakdown, 6 mA max collector current, 40 mA max forward current) must remain constant for functional equivalence.

Q: Are both parts compliant with current regulatory standards?

A: Both the OPB704G and OPB704GWZ are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the primary advantage of selecting the OPB704GWZ over the OPB704G?

A: The OPB704GWZ maintains active product status with current manufacturing availability, whereas the OPB704G is classified as obsolete. The pre-wired configuration of the OPB704GWZ may reduce assembly labor in applicable designs.

Q: Are there differences in sensing performance between these parts?

A: No. Both components operate at identical sensing distance, employ reflective sensing methodology, and deliver equivalent phototransistor output characteristics.
