OPB480L11Z Equivalent & Substitute Parts

Part Overview

The OPB480L11Z is an optical through-beam sensor module manufactured by TT Electronics/Optek Technology, part of the Photologic® series. This component is a 0.125" (3.18mm) slot optical sensor with wire leads, designed for chassis mount applications. The part is currently active and in production with 1028 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, design flexibility, or application-specific needs within the same product family.

Substitute Part Grouping Explanation

Substitute parts for the OPB480L11Z are qualified based on matching the following critical parameters:

Sensing distance: 0.125" (3.18mm)
Sensing method: Through-beam optical detection
Output configuration: Pull-up resistor with buffer output
Voltage supply range: 4.5V ~ 16V
Current consumption: 7.5 mA
Response time: 50ns
Operating temperature range: -40°C ~ 85°C

Engineering Selection Recommendations

All four optical sensor modules—OPB480L11Z, OPB480T11Z, OPB490P11Z, and OPB490T11Z—are active products manufactured by TT Electronics/Optek Technology and maintain full compliance with ROHS3 regulations and REACH directives. Each part carries identical electrical specifications, environmental operating ranges, and mechanical mounting configurations.

Selection between these parts is determined by availability and application requirements within the 0.125" (3.18mm) through-beam optical sensing category. All parts are suitable for direct substitution in circuits designed for the OPB480L11Z, provided the application does not impose additional constraints beyond the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can OPB480T11Z, OPB490P11Z, or OPB490T11Z be used as direct replacements for OPB480L11Z?

A: Yes. All four parts share identical electrical performance specifications, including voltage supply range (4.5V ~ 16V), current consumption (7.5 mA), response time (50ns), and operating temperature range (-40°C ~ 85°C). They are functionally equivalent for through-beam optical sensing applications at 0.125" (3.18mm) slot width.

Q: What is the difference between OPB480 and OPB490 base product numbers?

A: The base product numbers indicate different product lines within the Photologic® series. Both OPB480 and OPB490 variants meet the same electrical and mechanical specifications for this application. Selection between them is based on availability and inventory status.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. OPB480L11Z, OPB480T11Z, OPB490P11Z, and OPB490T11Z are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What does the suffix designation (L, T, P) indicate?

A: Suffix designations represent manufacturing or packaging variants within the Photologic® series. All variants specified maintain identical electrical performance and mechanical compatibility for through-beam optical sensing applications.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The OPB480L11Z, OPB480T11Z, OPB490P11Z, and OPB490T11Z are mechanically and electrically interchangeable for chassis mount wire lead configurations. No circuit modifications are required for substitution.
