OPB463T11 Equivalent & Substitute Parts

Part Overview

The OPB463T11 is an optical sensor manufactured by TT Electronics/Optek Technology, part of the Photologic® series. This through-beam optical sensor is designed for PCB mount applications with a 0.125" (3.18mm) sensing distance. The component features NPN open collector inverted output configuration and operates across a wide supply voltage range of 4.5V to 16V. As an active product with ROHS3 compliance and unlimited moisture sensitivity rating, the OPB463T11 remains in production. Substitute parts are identified when inventory constraints, lead time requirements, or procurement preferences necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OPB463T11 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that must remain identical:

• Sensing Distance: 0.125" (3.18mm)
• Sensing Method: Through-Beam
• Output Configuration: NPN - Open Collector, Inverted
• Mounting Type: Through Hole
• Voltage Supply Range: 4.5V ~ 16V
• Current Supply: 7.5 mA
• Response Time: 50ns
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: PCB Mount
• Series: Photologic®
• Manufacturer: TT Electronics/Optek Technology

Only parts matching all these parameters across the OPB463 base product family are classified as direct substitutes. Variations in any of these specifications disqualify a part from substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The OPB463N11 is a direct substitute for the OPB463T11. Both components are manufactured by TT Electronics/Optek Technology within the Photologic® series and share identical electrical specifications, mechanical configuration, and compliance certifications. Both parts maintain active product status and ROHS3 compliance. Selection between these parts should be based on inventory availability and procurement lead times, as no functional or performance differentiation exists between them. The OPB463N11 currently maintains higher inventory levels (1875 Pcs) compared to the OPB463T11 (927 Pcs), which may influence sourcing decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can the OPB463N11 be used as a direct replacement for the OPB463T11?

A: Yes. The OPB463N11 is a direct substitute. Both parts are identical in electrical performance, sensing characteristics, output configuration, and mechanical mounting. No circuit modifications or design changes are required for substitution.

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both the OPB463T11 and OPB463N11 carry identical ROHS3 compliance status, REACH unaffected designation, and moisture sensitivity level (MSL 1 - Unlimited). Both are classified under ECCN EAR99 and HTSUS 8541.49.8000.

Q: What determines whether a part qualifies as a substitute for the OPB463T11?

A: A substitute part must match all critical parameters: 0.125" (3.18mm) sensing distance, through-beam sensing method, NPN open collector inverted output, through-hole mounting, 4.5V to 16V supply voltage, 7.5 mA supply current, 50ns response time, -40°C to 85°C operating temperature range, and PCB mount package configuration. Parts from the OPB463 base product family manufactured by TT Electronics/Optek Technology that meet these specifications are eligible substitutes.

Q: Does the packaging format affect substitution eligibility?

A: No. Both parts are supplied in bulk packaging. The PCB mount package configuration is identical, ensuring mechanical and electrical compatibility in the same circuit board layout.

Q: Are there any temperature or voltage operating range differences?

A: No. Both parts operate identically across the full -40°C to 85°C temperature range and 4.5V to 16V supply voltage range. No derating or operational limitations differ between the two parts.
