OPB483P11 Equivalent & Substitute Parts

Part Overview

The OPB483P11 is an optical sensor from TT Electronics/Optek Technology's Photologic® series, designed as a through-beam sensor with 0.125" (3.18mm) sensing distance and wire lead module packaging. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

The OPB483P11 operates as an NPN open collector sensor with inverted output, suitable for chassis mount applications requiring through-beam optical detection. Substitution is driven by product lifecycle status and the need for active, supported alternatives that maintain electrical and functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the OPB483P11 is determined by strict equivalence across the following critical parameters:

• Sensing Distance: 0.125" (3.18mm) — all substitutes maintain identical sensing range
• Sensing Method: Through-Beam — optical detection principle remains unchanged
• Output Configuration: NPN - Open Collector, Inverted — electrical interface compatibility
• Voltage Supply Range: 4.5V ~ 16V — power supply compatibility
• Current Supply: 7.5 mA — current draw specification
• Response Time: 50ns — switching speed performance
• Operating Temperature Range: -40°C ~ 85°C — thermal operating envelope

Substitute parts are grouped into two categories based on mounting configuration:

Wire Lead Module Substitutes (Chassis Mount): OPB483P11Z, OPB483L11Z, OPB493T11Z — direct mechanical and electrical equivalents with active product status and RoHS3 compliance.

PCB Mount Alternatives (Through Hole): OPB463N11, OPB473N11 — functionally equivalent sensors with identical electrical specifications but different mounting interface, suitable for applications where PCB mounting is preferred.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Wire Lead Module, Chassis Mount):

OPB483P11Z is the primary substitute, offering identical electrical and mechanical specifications with active product status and RoHS3 compliance. This part provides the most direct path for obsolescence mitigation while maintaining full compatibility with existing designs.

OPB483L11Z and OPB493T11Z are functionally equivalent alternatives, both active and RoHS3 compliant, suitable where OPB483P11Z availability is constrained.

For Design Revision (PCB Mount Alternative):

OPB463N11 and OPB473N11 provide electrical equivalence with modified mounting interface (through-hole PCB mount instead of chassis mount wire leads). These parts are recommended only when design revision to accommodate PCB mounting is feasible. Both are active, RoHS3 compliant, and available in higher inventory quantities.

All substitute parts maintain REACH unaffected status and identical ECCN/HTSUS classifications as the original OPB483P11.

Frequently Asked Questions (FAQ)

Q: Can OPB483P11Z be used as a direct drop-in replacement for OPB483P11?

A: Yes. OPB483P11Z maintains identical electrical specifications (4.5V ~ 16V supply, 7.5 mA current, 50ns response time, -40°C ~ 85°C operating range), output configuration (NPN open collector inverted), sensing distance (0.125"), and package type (module with wire leads). The primary difference is product status (active vs. obsolete) and RoHS3 compliance.

Q: What is the difference between wire lead module and PCB mount versions?

A: Wire lead module versions (OPB483P11Z, OPB483L11Z, OPB493T11Z) feature chassis mount configuration with wire leads for direct connection. PCB mount versions (OPB463N11, OPB473N11) use through-hole mounting for direct PCB integration. All maintain identical electrical performance and sensing specifications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All active substitute parts (OPB483P11Z, OPB483L11Z, OPB493T11Z, OPB463N11, OPB473N11) are RoHS3 compliant. The original OPB483P11 is RoHS non-compliant.

Q: Which substitute part has the highest inventory availability?

A: OPB463N11 (PCB mount) has the highest inventory at 1875 pieces. Among wire lead module versions, OPB483P11Z has the highest availability at 1131 pieces.

Q: Can PCB mount versions be used in applications originally designed for wire lead modules?

A: No. PCB mount versions require design modification to accommodate through-hole mounting. Wire lead module versions (OPB483P11Z, OPB483L11Z, OPB493T11Z) are required for direct compatibility with existing chassis mount designs.
