OPB932W51Z Equivalent & Substitute Parts

Part Overview

The OPB932W51Z is an optical sensor from TT Electronics/Optek Technology's Photologic® series, designed as a through-beam sensor module with 0.125" (3.18mm) sensing distance and wire leads for chassis mount applications. This component operates with totem pole inverted output configuration and is actively supported with 1139 units in stock. Substitute parts are necessary when the primary part becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from compatible variants within the same product family.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OPB932W51Z is determined by strict equivalence across the following critical parameters:

• Sensing Distance: 0.125" (3.18mm)
• Sensing Method: Through-Beam
• Output Configuration: Totem Pole, Inverted
• Mounting Type: Chassis Mount
• Voltage Supply Range: 4.75V ~ 5.25V
• Current Supply: 15 mA
• Response Time: 70ns
• Operating Temperature Range: -40°C ~ 70°C
• Package Type: Module, Wire Leads
• Series: Photologic®
• Compliance: ROHS3 Compliant, REACH Unaffected

All substitute parts listed maintain identical electrical and mechanical specifications across these parameters. Substitution is valid when the application requires component interchange without circuit modification or performance degradation.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical compatibility with the OPB932W51Z. Selection among active parts should prioritize inventory availability and supply chain reliability. OPB992P51Z offers the highest inventory level at 69,800 units, followed by OPB992N55Z at 20,299 units, providing superior supply security for high-volume applications.

OPB982N55Z carries obsolete product status and should be avoided for new designs or long-term production commitments, despite meeting all electrical and mechanical specifications. Active status parts—OPB942W55Z, OPB982P51Z, OPB982T51Z, OPB992L51Z, OPB992N55Z, OPB992P51Z, and OPB992T51Z—are suitable for direct substitution in applications where the OPB932W51Z is specified.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can OPB992P51Z replace OPB932W51Z in existing designs?

A: Yes. OPB992P51Z maintains identical electrical specifications (4.75V–5.25V supply, 15 mA current, 70ns response time), mechanical configuration (0.125" sensing distance, through-beam method, totem pole inverted output), and package type (module with wire leads). Direct substitution is valid without circuit modification.

Q: What is the difference between the substitute part numbers?

A: Substitute parts differ in base product number designation (OPB932, OPB942, OPB982, OPB992) and suffix codes (W51Z, P51Z, T51Z, L51Z, N55Z). These designations reflect internal product line variants within the Photologic® series. All variants listed maintain identical functional and electrical parameters for the specified application.

Q: Why is OPB982N55Z marked as obsolete?

A: OPB982N55Z carries obsolete product status per manufacturer classification. While it meets all electrical and mechanical specifications, obsolete designation indicates discontinued production and limited future availability. Active alternatives should be prioritized for new designs and production planning.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed, including the obsolete OPB982N55Z, maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence with the OPB932W51Z.

Q: Which substitute part offers the best supply availability?

A: OPB992P51Z provides the highest inventory level at 69,800 units in stock, followed by OPB992N55Z at 20,299 units. Both are active products suitable for applications requiring supply security and long-term availability.
