OPB962T55 Equivalent & Substitute Parts

Part Overview

The OPB962T55 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) PCB mount configuration and is classified as an active product. The sensor operates with totem pole inverted output configuration and is designed for applications requiring precise through-beam detection at short sensing distances. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility necessitate alternative part numbers within the same functional and electrical specification range.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OPB962T55 are qualified based on electrical and mechanical parameter equivalence. All substitute parts maintain identical specifications across the following critical parameters:

• Sensing distance: 0.125" (3.18mm)
• Sensing method: Through-beam
• Output configuration: Totem pole, inverted
• Mounting type: Through hole
• Supply voltage range: 4.75V ~ 5.25V
• Supply current: 15 mA
• Response time: 70ns
• Operating temperature range: -40°C ~ 70°C
• Package type: PCB mount
• Regulatory compliance: ROHS3 compliant, REACH unaffected

Substitution is valid across OPB962 and OPB972 base product families. Suffix variations (N51, N55, L51, T55) represent packaging or lead configuration differences that do not affect electrical performance or functional compatibility in through-beam optical sensing applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full ROHS3 compliance with REACH unaffected designation. Selection among OPB962T55, OPB962N51, OPB962N55, OPB972L51, OPB972N51, and OPB972T55 is determined by availability and packaging configuration requirements. Each part is functionally equivalent for through-beam optical sensing applications operating within the specified voltage, current, temperature, and response time parameters. Inventory levels vary across part numbers, with OPB972N51 offering the highest stock position at 2905 units.

Frequently Asked Questions (FAQ)

Q: Are all listed substitute parts electrically identical to the OPB962T55? A: Yes. All substitute parts operate at identical voltage (4.75V ~ 5.25V), current (15 mA), response time (70ns), and temperature range (-40°C ~ 70°C) specifications. Electrical performance is equivalent across all listed part numbers.

Q: What do the suffix designations (N51, N55, L51, T55) represent? A: Suffix variations indicate packaging or lead configuration differences. These differences do not affect electrical functionality or sensing performance in through-beam applications.

Q: Can OPB972 series parts replace OPB962 series parts? A: Yes. Both OPB962 and OPB972 base product families share identical electrical and mechanical specifications for sensing distance, output configuration, supply parameters, and operating conditions. Substitution between families is valid.

Q: What is the significance of the different inventory levels? A: Inventory quantities reflect current stock availability. Higher inventory levels may indicate shorter lead times for procurement. All parts are active products from the same manufacturer.

Q: Are all substitute parts RoHS and REACH compliant? A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.
