OPB932W55Z Equivalent & Substitute Parts

Part Overview

The OPB932W55Z is an optical sensor manufactured by TT Electronics/Optek Technology, part of the Photologic® series. This through-beam optical sensor features a 0.125" (3.18mm) sensing distance and is designed for chassis mount applications with wire leads. The component is currently active in production with 866 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 alternatives within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OPB932W55Z 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 characteristics and mechanical specifications. Substitution is valid across all listed alternatives without circuit modification or performance degradation.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status except OPB982N55Z, which is classified as obsolete. For new designs and ongoing production, selection should prioritize active parts. OPB992P51Z offers the highest inventory availability at 69,800 units, providing supply chain stability. OPB992N55Z provides secondary availability at 20,299 units. All active alternatives are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. OPB982N55Z, despite obsolete classification, remains electrically and mechanically equivalent and may be used only when existing inventory must be consumed or when supply constraints necessitate utilization of remaining stock.

Frequently Asked Questions (FAQ)

Q: Can OPB932W55Z be directly replaced with any of the listed substitute parts?

A: Yes. All listed substitute parts are electrically and mechanically equivalent. Direct substitution is valid without circuit modification, provided the part is mounted identically and connected to the same voltage supply range (4.75V ~ 5.25V).

Q: What is the difference between OPB932W55Z and OPB942W55Z?

A: Both parts are functionally identical across all specified electrical and mechanical parameters. The difference lies in the base product number designation (OPB932 versus OPB942), which reflects internal manufacturer product line organization. No performance or compatibility difference exists.

Q: Are OPB982 and OPB992 series parts interchangeable with OPB932W55Z?

A: Yes. OPB982 and OPB992 series parts listed maintain identical sensing distance, output configuration, voltage supply, current draw, response time, operating temperature range, and package type. All are through-beam optical sensors with totem pole inverted output and chassis mount configuration.

Q: Should OPB982N55Z be used in new designs?

A: No. OPB982N55Z is classified as obsolete. For new designs, select from active parts: OPB932W55Z, OPB942W55Z, OPB982P51Z, OPB982T51Z, OPB992L51Z, OPB992N55Z, OPB992P51Z, or OPB992T51Z. OPB982N55Z may be used only to consume existing inventory in legacy applications.

Q: What is the significance of the suffix letters (W, P, T, L, N) in the part numbers?

A: The suffix designations are part of the manufacturer's product coding scheme. All listed parts with these suffixes maintain identical electrical specifications and mechanical compatibility. Suffix differences do not affect substitution eligibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed parts, including the obsolete OPB982N55Z, are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Which substitute part offers the best supply availability?

A: OPB992P51Z provides the highest inventory level at 69,800 units, followed by OPB992N55Z at 20,299 units. Both are active products suitable for new designs and ongoing production.
