Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OPB707B is determined by strict equivalence across the following critical parameters:

• Sensing distance: 0.050" (1.27mm)
• Sensing method: Reflective
• Output type: Photodarlington
• Electrical ratings: Collector-emitter breakdown voltage ≤ 15 V, collector current ≤ 125 mA, forward current ≤ 50 mA
• Mounting configuration: Through hole PCB mount
• Operating temperature range: -40°C ~ 85°C minimum
• Environmental compliance: ROHS3 compliant, REACH unaffected

The OPB707C meets all substitution criteria and is classified as the manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The OPB707C is the direct substitute for the OPB707B. Both components share identical electrical specifications, sensing characteristics, and environmental compliance certifications. The primary distinction is product status: the OPB707B is obsolete while the OPB707C maintains active production status. For new designs and ongoing production requiring reflective optical sensing at 0.050" (1.27mm) with photodarlington output, the OPB707C is the appropriate selection. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the OPB707C directly replace the OPB707B in existing designs?

A: Yes. The OPB707C is electrically and mechanically equivalent to the OPB707B across all specified parameters, including sensing distance, output type, electrical ratings, and operating temperature range. No circuit modifications are required.

Q: What is the significance of the OPB707B being obsolete?

A: Obsolete status indicates the OPB707B is no longer manufactured. The OPB707C provides continuity for applications requiring this sensor type, as it maintains identical functional and electrical characteristics while remaining in active production.

Q: Are there packaging differences between OPB707B and OPB707C?

A: Both components use PCB mount through-hole packaging. The OPB707C is supplied in bulk packaging, while the OPB707B packaging specification was not provided. This distinction does not affect electrical or mechanical compatibility.

Q: Do both parts meet current environmental compliance standards?

A: Yes. Both the OPB707B and OPB707C are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components in industrial applications.

Q: What are the critical parameters for substitution in reflective optical sensor applications?

A: Substitution eligibility requires equivalence in sensing distance (0.050"), sensing method (reflective), output type (photodarlington), electrical ratings (15 V breakdown, 125 mA collector current, 50 mA forward current), mounting configuration (through-hole PCB mount), and operating temperature range (-40°C to 85°C).
