OPB982T55Z Equivalent & Substitute Parts

Part Overview

The OPB982T55Z is a through-beam optical sensor module manufactured by TT Electronics/Optek Technology, part of the Photologic® series. This component operates as a 0.125" (3.18mm) sensing distance optical sensor with totem pole inverted output configuration, designed for chassis mount applications. The part is currently active in production with 830 units in stock. Substitute parts are necessary when the primary part becomes unavailable, when alternative packaging or lead configurations are required, or when inventory constraints necessitate component alternatives that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OPB982T55Z are qualified based on 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
• Compliance: ROHS3 Compliant, REACH Unaffected

All substitute parts listed maintain identical electrical performance and mechanical compatibility. Variations exist only in base product number designations (OPB942, OPB982, OPB992 series) and internal packaging codes, which do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All active substitute parts (OPB942W55Z, OPB982P51Z, OPB982T51Z, OPB992L51Z, OPB992N55Z, OPB992P51Z, OPB992T51Z) maintain full compliance with ROHS3 and REACH requirements, matching the primary part OPB982T55Z. These parts are functionally equivalent and directly interchangeable in circuit designs requiring through-beam optical sensing at 0.125" (3.18mm) distance with totem pole inverted output.

OPB992N55Z and OPB992P51Z offer the highest inventory availability (20,299 and 69,800 units respectively), providing supply chain flexibility. OPB982P51Z and OPB982T51Z maintain the same base product number as the primary part, offering closest part family alignment.

OPB982N55Z is classified as obsolete and should not be selected for new designs, though existing inventory remains available for legacy system maintenance.

Frequently Asked Questions (FAQ)

Q: Can OPB992 series parts replace OPB982 series parts? A: Yes. Both OPB982 and OPB992 base product numbers share identical electrical specifications, sensing distance, output configuration, and operating parameters. The substitution is electrically and mechanically valid.

Q: What do the suffix codes (T55Z, P51Z, T51Z, L51Z, N55Z) represent? A: Suffix codes indicate internal packaging and lead configuration variants. All listed variants maintain the same functional performance and are interchangeable in circuit applications.

Q: Is OPB942W55Z compatible with OPB982T55Z applications? A: Yes. OPB942W55Z meets all electrical and mechanical specifications of OPB982T55Z, including sensing distance, output configuration, voltage/current requirements, and response time.

Q: Should OPB982N55Z be used in new designs? A: No. OPB982N55Z is classified as obsolete. For new designs, select from active status parts: OPB942W55Z, OPB982P51Z, OPB982T51Z, OPB992L51Z, OPB992N55Z, OPB992P51Z, or OPB992T51Z.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the primary part OPB982T55Z.

Q: What is the difference between wire lead packaging options? A: All parts listed use Module, Wire Leads packaging. Variations in part numbers reflect internal manufacturing codes and lead configurations that do not affect functional interchangeability in standard through-beam optical sensing applications.
