Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OPB983P11 are qualified based on strict electrical and mechanical parameter matching within the Photologic® optical sensor family. All substitute parts maintain identical specifications across the following critical parameters:

• Sensing Distance: 0.125" (3.18mm)
• Sensing Method: Through-Beam
• Output Configuration: NPN - Open Collector, Inverted
• Mounting Type: Chassis Mount
• Current - Supply: 15 mA
• Voltage - Supply: 4.75V ~ 5.25V
• Response Time: 70ns
• Operating Temperature: -40°C ~ 70°C
• Package / Case: Module, Wire Leads
• Category: Optical Sensors
• Series: Photologic®

Substitutes are grouped into two categories: direct equivalents with active product status and manufacturer-recommended alternatives. The primary distinction between substitute parts lies in packaging configuration (bulk) and RoHS compliance status (ROHS3 Compliant), which represent improvements over the obsolete original part.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the OPB983P11 across all specified electrical and mechanical parameters. The primary selection criteria are product status and regulatory compliance.

The OPB983P11 is obsolete and RoHS non-compliant. All substitute parts listed are active products with ROHS3 compliance, making them suitable for new designs and systems requiring regulatory adherence. OPB983T51Z offers the highest inventory availability at 20,199 units, providing supply chain stability for high-volume applications. OPB983P11Z represents the closest direct equivalent with active status and improved compliance. OPB933W51Z and OPB943W51Z are manufacturer-recommended alternatives with substantial inventory levels, suitable for applications where base product number variation is acceptable within the Photologic® series.

Frequently Asked Questions (FAQ)

Q: Can I directly replace OPB983P11 with any of the listed substitutes?

A: Yes. All substitute parts maintain identical electrical specifications (15 mA supply current, 4.75V ~ 5.25V supply voltage, 70ns response time), mechanical configuration (chassis mount, wire leads), and functional parameters (0.125" sensing distance, through-beam method, NPN open collector inverted output, -40°C ~ 70°C operating range). Direct pin-for-pin and functional replacement is supported.

Q: What is the difference between OPB983P11Z and OPB983T51Z?

A: Both parts are electrically and mechanically identical. The primary difference is inventory availability: OPB983T51Z has significantly higher stock (20,199 units) compared to OPB983P11Z (998 units). Both are active products with ROHS3 compliance.

Q: Why is the original OPB983P11 marked as obsolete?

A: The OPB983P11 is no longer in active production. Substitute parts with active status and improved RoHS compliance are available from the same manufacturer and series, providing equivalent functionality with better long-term supply assurance and regulatory compliance.

Q: Are there any packaging differences between substitutes?

A: All substitute parts use identical module packaging with wire leads. The primary packaging distinction is that substitutes are supplied in bulk configuration, whereas the original part may have had different packaging. This does not affect electrical or mechanical compatibility.

Q: Which substitute should I select for new designs?

A: For new designs, select from active products with ROHS3 compliance. OPB983T51Z is recommended for high-volume applications due to superior inventory availability. OPB983P11Z is recommended for designs requiring the closest direct part number match to the original specification.
