OPB460T11 Equivalent & Substitute Parts

Part Overview

The OPB460T11 is an optical sensor manufactured by TT Electronics/Optek Technology, part of the Photologic® series. This through-beam optical sensor is designed for PCB mount applications with a 0.125" (3.18mm) sensing distance. The component is Active status and widely used in industrial automation, position detection, and object sensing applications. Finding equivalent or substitute parts may be necessary due to inventory constraints, supply chain considerations, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OPB460T11 are determined by strict equivalence in the following critical parameters:

• Sensing Distance: 0.125" (3.18mm) — all substitutes must maintain identical sensing range
• Sensing Method: Through-Beam — optical detection principle must remain unchanged
• Output Configuration: Pull-Up Resistor, Buffer — signal output characteristics must be compatible
• Voltage Supply Range: 4.5V ~ 16V — power supply compatibility is mandatory
• Current Supply: 7.5 mA — power consumption must match
• Response Time: 50ns — switching speed must be equivalent
• Operating Temperature: -40°C ~ 85°C — thermal operating range must be maintained
• Series: Photologic® — product line consistency
• Product Status: Active — component must be in active production

The OPB460T11 has two primary substitute categories: direct PCB mount equivalents (OPB460N11, OPB470N11) and a chassis mount module variant (OPB490T11Z). All three parts share identical electrical specifications and sensing characteristics but differ in mechanical mounting configuration.

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and functional equivalence to the OPB460T11. Selection between substitutes depends on mechanical integration requirements:

OPB460N11: Direct substitute for OPB460T11. Identical PCB mount through-hole configuration. Recommended for direct replacement in existing PCB designs without layout modifications.

OPB470N11: Functionally equivalent with identical electrical specifications and PCB mount configuration. Suitable for applications where OPB460N11 inventory is unavailable. Base product number differs (OPB470 vs OPB460) but all critical parameters remain unchanged.

OPB490T11Z: Functionally equivalent with identical electrical specifications but features chassis mount configuration with wire leads instead of PCB mount through-hole. Suitable only for applications where chassis mount integration is required. Not recommended for direct PCB mount replacement without mechanical redesign.

All parts are Active status products from TT Electronics/Optek Technology, ROHS3 compliant, and carry identical compliance certifications (REACH Unaffected, ECCN EAR99, HTSUS 8541.49.8000).

Frequently Asked Questions (FAQ)

Q: Can OPB460N11 be used as a direct replacement for OPB460T11? A: Yes. Both parts share identical electrical specifications, sensing characteristics, and PCB mount through-hole configuration. No circuit or layout modifications are required.

Q: What is the difference between OPB460T11 and OPB470N11? A: The base product numbers differ (OPB460 vs OPB470), but all electrical parameters, sensing distance, output configuration, and mounting type are identical. Both are through-hole PCB mount components with equivalent performance.

Q: Can OPB490T11Z replace OPB460T11 in a PCB mount application? A: No. OPB490T11Z uses chassis mount configuration with wire leads, while OPB460T11 is a through-hole PCB mount component. Mechanical integration is fundamentally different and requires circuit board redesign.

Q: Are all substitute parts ROHS3 compliant? A: Yes. OPB460N11, OPB470N11, and OPB490T11Z are all ROHS3 compliant with identical compliance status to the OPB460T11.

Q: What is the sensing distance for all these optical sensors? A: All parts maintain a sensing distance of 0.125" (3.18mm) with through-beam sensing method.

Q: Do the substitute parts have the same power supply requirements? A: Yes. All substitute parts operate within the 4.5V ~ 16V supply range with 7.5 mA current consumption and 50ns response time.

Q: Which substitute should I choose if I need maximum inventory availability? A: OPB490T11Z has the highest inventory (4186 Pcs), followed by OPB460N11 (2779 Pcs) and OPB470N11 (1910 Pcs). However, inventory selection must be secondary to mechanical compatibility requirements.
