OPB483P11Z Equivalent & Substitute Parts

Part Overview

The OPB483P11Z is an optical sensor manufactured by TT Electronics/Optek Technology, part of the Photologic® series. This through-beam optical sensor operates at a sensing distance of 0.125" (3.18mm) with NPN open collector inverted output configuration. The device features wire leads for chassis mount applications and is actively produced. Substitute parts are identified when equivalent electrical performance and sensing characteristics are required but alternative mounting or packaging configurations are preferred for specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OPB483P11Z are qualified based on the following criteria:

Electrical Equivalence: All substitute parts maintain identical sensing distance (0.125" / 3.18mm), sensing method (through-beam), output configuration (NPN open collector inverted), supply voltage range (4.5V ~ 16V), supply current (7.5 mA), and response time (50ns).

Environmental Compliance: All substitute parts share the same operating temperature range (-40°C ~ 85°C), RoHS3 compliance status, and moisture sensitivity level (MSL 1 - Unlimited).

Manufacturer Consistency: All parts are manufactured by TT Electronics/Optek Technology within the Photologic® series and maintain active product status.

Differentiation Factor: Substitution is determined solely by mounting type and package configuration. The OPB483P11Z uses chassis mount with wire leads, while substitute options provide alternative mounting solutions (through-hole PCB mount or alternative wire lead configurations) for different assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain full electrical and functional equivalence with identical sensing parameters, output characteristics, and environmental specifications. Selection between OPB483P11Z, OPB463N11, and OPB493T11Z is determined by mechanical integration requirements:

OPB483P11Z is specified for applications requiring chassis mount configuration with wire lead connections.

OPB463N11 is selected when through-hole PCB mount integration is required, providing direct board-level mounting without external mechanical fixtures.

OPB493T11Z provides an alternative chassis mount wire lead option within the same electrical specification set.

All parts carry ROHS3 compliance and active product status, ensuring continued availability and regulatory alignment for new designs and production environments.

Frequently Asked Questions (FAQ)

Q: Can OPB463N11 replace OPB483P11Z in an existing assembly?

A: Electrical substitution is valid; however, mechanical integration differs. OPB463N11 uses through-hole PCB mount while OPB483P11Z uses chassis mount with wire leads. Board layout and mechanical fixture modifications are required.

Q: Are all three parts electrically identical?

A: Yes. All three parts share identical sensing distance (0.125" / 3.18mm), output configuration (NPN open collector inverted), supply voltage (4.5V ~ 16V), current draw (7.5 mA), response time (50ns), and operating temperature range (-40°C ~ 85°C).

Q: What is the primary difference between these substitute parts?

A: The primary difference is mounting configuration. OPB483P11Z and OPB493T11Z use chassis mount with wire leads, while OPB463N11 uses through-hole PCB mount. All maintain identical electrical performance.

Q: Are all parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Which part should be selected for new PCB designs?

A: OPB463N11 is recommended for new PCB designs requiring direct board-level integration through through-hole mounting. OPB483P11Z or OPB493T11Z are selected when external chassis mount fixtures are preferred.
