Substitute Part Grouping Explanation

Substitution for the OPB962P51 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must remain identical for direct substitution:

  • Sensing Distance: 0.125" (3.18mm)
  • Sensing Method: Through-Beam
  • Output Configuration: Totem Pole, Inverted
  • Mounting Type: Through Hole
  • Current - Supply: 15 mA
  • Voltage - Supply: 4.75V ~ 5.25V
  • Response Time: 70ns
  • Operating Temperature: -40°C ~ 70°C
  • Package / Case: PCB Mount

All substitute parts listed maintain these specifications without deviation. The OPB962 and OPB972 base product numbers represent different packaging and lead configurations within the Photologic® series, but electrical performance remains constant across all variants. Substitutes are grouped by product status (Active vs. Obsolete) and packaging type (Bulk vs. other configurations).

Engineering Selection Recommendations

All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The primary distinction between substitute options is product status: OPB962N51, OPB962N55, OPB962T51, OPB962T55, OPB972L51, OPB972N51, OPB972P51, OPB972T51, and OPB972T55 are all Active products, whereas the OPB962P51 is Obsolete.

For new designs and long-term system support, Active product variants are preferred due to ongoing manufacturer support and availability. The OPB962 series (OPB962N51, OPB962N55, OPB962T51, OPB962T55) and OPB972 series (OPB972L51, OPB972N51, OPB972P51, OPB972T51, OPB972T55) are electrically and functionally equivalent. Selection between OPB962 and OPB972 base product numbers depends on specific packaging and lead configuration requirements for your PCB assembly process. All variants maintain identical electrical performance and environmental specifications.

Frequently Asked Questions (FAQ)

Q: Can OPB962P51 be directly replaced with any of the listed substitute parts?

A: Yes. All substitute parts maintain identical electrical specifications, sensing distance, output configuration, and operating parameters. Direct substitution is supported without circuit modification.

Q: What is the difference between OPB962 and OPB972 base product numbers?

A: The OPB962 and OPB972 series differ in packaging and lead configuration variants. Electrical performance, sensing distance, output type, and operating specifications are identical across both series.

Q: Why is OPB962P51 listed as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. Active alternatives within the same product family provide equivalent functionality and are recommended for new designs and ongoing support.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting current environmental and regulatory standards.
