OPB490N11Z Equivalent & Substitute Parts

Part Overview

The OPB490N11Z is a through-beam optical sensor from TT Electronics/Optek Technology's Photologic® series, designed for 0.125" (3.18mm) sensing distance applications. This component features wire lead module construction with chassis mount capability and is classified as obsolete. Due to its obsolete status, equivalent substitute parts with identical or compatible electrical and mechanical specifications are available to maintain design continuity and ensure supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OPB490N11Z is determined by strict equivalence across the following critical parameters:

• Sensing Distance: 0.125" (3.18mm)
• Sensing Method: Through-Beam
• Output Configuration: Pull-Up Resistor, Buffer
• Current - Supply: 7.5 mA
• Voltage - Supply: 4.5V ~ 16V
• Response Time: 50ns
• Operating Temperature: -40°C ~ 85°C
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Substitute parts are grouped into two categories based on mounting configuration:

Category 1: Module Wire Lead Substitutes (Chassis Mount) OPB490P11Z, OPB490T11Z, OPB480L11Z, OPB480T11Z — Direct functional equivalents with identical electrical specifications and wire lead module packaging.

Category 2: PCB Mount Alternatives (Through Hole) OPB460N11, OPB470N11 — Functionally equivalent sensors with identical electrical specifications but different mounting type (through hole PCB mount instead of chassis mount wire leads).

Parameter Comparison

Engineering Selection Recommendations

For Wire Lead Module Applications (Chassis Mount): OPB490P11Z and OPB490T11Z are direct active substitutes for the obsolete OPB490N11Z. Both maintain identical electrical specifications, sensing characteristics, and wire lead module packaging. OPB490T11Z offers higher inventory availability (4186 units) compared to OPB490P11Z (3665 units). OPB480L11Z and OPB480T11Z are functionally equivalent alternatives within the same mounting category, with OPB480T11Z providing superior stock levels (1100 units).

For PCB Mount Applications (Through Hole): OPB460N11 and OPB470N11 provide functional equivalence with identical electrical and sensing specifications but require PCB through-hole mounting instead of chassis mount wire leads. These parts are suitable only for designs that accommodate through-hole PCB mounting. OPB460N11 offers higher inventory (2779 units) than OPB470N11 (1910 units).

Compliance Considerations: All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original OPB490N11Z specification.

Frequently Asked Questions (FAQ)

Q: Can OPB490P11Z or OPB490T11Z be used as direct replacements for OPB490N11Z? A: Yes. Both parts are active substitutes with identical electrical specifications, sensing distance, response time, output configuration, and wire lead module packaging. The primary difference is product status: OPB490N11Z is obsolete while OPB490P11Z and OPB490T11Z are active.

Q: What is the difference between the wire lead module substitutes (OPB490P11Z, OPB490T11Z, OPB480L11Z, OPB480T11Z)? A: All four parts share identical electrical specifications and chassis mount wire lead packaging. Differences exist only in base product number designation (OPB490 vs. OPB480 series) and inventory availability. Selection should be based on design requirements and stock availability.

Q: Can OPB460N11 or OPB470N11 replace OPB490N11Z in existing designs? A: Electrical and sensing specifications are identical. However, these parts use through-hole PCB mounting instead of chassis mount wire leads. Substitution requires PCB layout modification to accommodate the different mounting type.

Q: Are all substitute parts RoHS and REACH compliant? A: Yes. All substitute parts listed maintain ROHS3 compliance and REACH unaffected status, matching the original OPB490N11Z specification.

Q: Which substitute part offers the best inventory availability? A: OPB490T11Z provides the highest stock level at 4186 units for wire lead module applications. For PCB mount alternatives, OPB460N11 offers 2779 units.

Q: Do all substitute parts operate within the same temperature and voltage ranges? A: Yes. All substitute parts operate across -40°C to 85°C and accept 4.5V to 16V supply voltage, matching the original OPB490N11Z specification.
