OPB470P11 Equivalent & Substitute Parts

Part Overview

The OPB470P11 is an optical sensor manufactured by TT Electronics/Optek Technology, part of the Photologic® series. This through-beam optical sensor features a 0.125" (3.18mm) sensing distance and PCB mount configuration. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. Substitute parts maintain identical electrical and mechanical specifications while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OPB470P11 are qualified based on the following critical parameters: sensing distance (0.125"), sensing method (through-beam), output configuration (pull-up resistor with buffer), voltage supply range (4.5V ~ 16V), current consumption (7.5 mA), response time (50ns), and operating temperature range (-40°C ~ 85°C). All substitute parts maintain these electrical specifications and RoHS3 compliance.

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 parameters. They differ only in packaging configuration (bulk vs. original packaging) and product status (active vs. obsolete).

Module Mount Substitute (OPB490P11Z): This part maintains all electrical specifications and sensing parameters but uses chassis mount with wire leads instead of PCB mount through-hole configuration. This substitute is applicable only when system redesign accommodates alternative mounting.

Parameter Comparison

Engineering Selection Recommendations

For direct replacement in existing PCB designs, OPB460N11, OPB460T11, and OPB470N11 are functionally equivalent to the obsolete OPB470P11. All three maintain identical electrical specifications, sensing parameters, and through-hole PCB mount configuration. These parts carry active product status and full RoHS3 compliance, ensuring long-term supply chain viability and regulatory compliance.

OPB490P11Z is electrically equivalent but requires mechanical redesign due to its chassis mount with wire leads configuration. This substitute is applicable only when system architecture permits alternative mounting methods.

Selection priority should favor parts with highest current inventory availability: OPB490P11Z (3665 pcs), OPB460N11 (2779 pcs), and OPB470N11 (1910 pcs) offer superior supply security compared to OPB460T11 (698 pcs).

Frequently Asked Questions (FAQ)

Q: Can OPB460N11, OPB460T11, and OPB470N11 be used interchangeably with OPB470P11?

A: Yes. These three parts maintain identical electrical specifications, sensing distance, output configuration, voltage supply range, current consumption, response time, and operating temperature range. The primary differences are product status (active vs. obsolete) and packaging configuration. All three are direct functional equivalents for PCB mount applications.

Q: What is the difference between OPB460N11 and OPB460T11?

A: Both parts share identical electrical and sensing specifications. The difference lies in packaging configuration (bulk vs. alternative packaging). Selection between these two depends on procurement requirements and packaging preferences rather than functional performance.

Q: Can OPB490P11Z replace OPB470P11 in existing designs?

A: OPB490P11Z is electrically and functionally equivalent but uses a different mounting method (chassis mount with wire leads vs. through-hole PCB mount). Direct substitution requires mechanical redesign of the mounting interface. This part is suitable only for new designs or systems where mounting reconfiguration is feasible.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. OPB460N11, OPB460T11, OPB470N11, and OPB490P11Z are all ROHS3 compliant and REACH unaffected, matching the compliance profile of the original OPB470P11.

Q: Which substitute part offers the best supply availability?

A: OPB490P11Z has the highest inventory (3665 pcs), followed by OPB460N11 (2779 pcs) and OPB470N11 (1910 pcs). For PCB mount applications specifically, OPB460N11 offers the best availability among direct mechanical equivalents.
