OPB460L11 Equivalent & Substitute Parts

Part Overview

The OPB460L11 is a through-beam optical sensor manufactured by TT Electronics/Optek Technology, designed for 0.125" (3.18mm) PCB mount applications. This sensor features pull-up resistor and buffer output configuration, operating across a 4.5V to 16V supply range with a 50ns response time. The OPB460L11 is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and component procurement.

Substitute Part Grouping Explanation

Substitute parts for the OPB460L11 are qualified based on matching the following critical parameters: sensing distance (0.125"), sensing method (through-beam), output configuration (pull-up resistor with buffer), supply voltage range (4.5V ~ 16V), current consumption (7.5 mA), response time (50ns), and operating temperature range (-40°C ~ 85°C). All substitute parts maintain ROHS3 compliance and REACH unaffected status.

Substitutes are grouped into two categories:

PCB Mount Substitutes (OPB460N11, OPB460T11, OPB470N11): These parts maintain identical mounting type (through hole, PCB mount) and all electrical specifications. They differ only in packaging format and product status (active vs. obsolete).

Module Mount Substitute (OPB490T11Z): This part matches all electrical and sensing specifications but uses chassis mount with wire leads instead of PCB mount. Selection of this substitute requires mechanical redesign of the mounting interface.

Engineering Selection Recommendations

For direct replacement of OPB460L11 in existing PCB designs, OPB460N11 and OPB460T11 are the primary substitutes. Both parts are active products with full ROHS3 compliance and identical electrical and mechanical specifications. OPB460N11 offers the highest inventory availability (2779 pcs) compared to OPB460T11 (698 pcs).

OPB470N11 provides an alternative PCB mount substitute with equivalent performance specifications and active product status. This part maintains 1910 pcs in inventory.

OPB490T11Z is suitable only when mechanical redesign is acceptable, as it requires chassis mount installation with wire leads instead of PCB mount through-hole configuration. This part has the highest inventory level (4186 pcs) and maintains all electrical specifications.

All substitute parts carry ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original OPB460L11.

Frequently Asked Questions (FAQ)

Q: Can OPB460N11 or OPB460T11 be used as direct drop-in replacements for OPB460L11?

A: Yes. Both OPB460N11 and OPB460T11 maintain identical sensing distance, sensing method, output configuration, supply voltage range, current consumption, response time, and operating temperature specifications. The through-hole PCB mount configuration is identical, allowing direct substitution without circuit board redesign.

Q: What is the difference between OPB460N11 and OPB460T11?

A: Both parts share identical electrical and mechanical specifications. The difference is packaging format (bulk) and inventory availability. OPB460N11 has 2779 pcs in stock versus 698 pcs for OPB460T11.

Q: Why is OPB470N11 listed as a substitute if it has a different base product number?

A: OPB470N11 matches all critical electrical parameters (sensing distance, sensing method, output configuration, voltage range, current, response time, and operating temperature) and mounting type (through-hole PCB mount). The base product number difference does not affect functional equivalence for the specified application.

Q: Can OPB490T11Z replace OPB460L11 without PCB modifications?

A: No. OPB490T11Z uses chassis mount with wire leads instead of through-hole PCB mount. Substitution requires mechanical redesign of the mounting interface and circuit board layout modifications.

Q: Are all substitute parts RoHS compliant?

A: Yes. OPB460N11, OPB460T11, OPB470N11, and OPB490T11Z are all ROHS3 compliant and REACH unaffected, matching the regulatory status of OPB460L11.
