Key Parameters

Substitute Part Grouping Explanation

Substitution of the HOA0860-T55 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Sensing distance: 0.125" (3.18mm)
• Sensing method: Through-Beam
• Output configuration: Transistor or Phototransistor
• Mounting type: Through Hole
• Package type: PCB Mount
• Operating temperature range: -40°C ~ 85°C minimum
• Electrical ratings: Current and voltage specifications must meet or exceed the original part

Substitution Logic: The OPB360T51 qualifies as a direct substitute because it maintains identical sensing distance, through-beam sensing method, PCB mount configuration, and operating temperature range. Both components feature transistor-based output stages with matching electrical current and voltage specifications. The phototransistor output configuration of the OPB360T51 is functionally compatible with the transistor output of the HOA0860-T55 in through-beam sensing applications.

Engineering Selection Recommendations

Primary Substitute: OPB360T51

The OPB360T51 manufactured by TT Electronics/Optek Technology is the qualified substitute for the obsolete HOA0860-T55. Selection of this substitute is based on the following engineering factors:

1. Electrical Compatibility: All critical electrical parameters are identical, including maximum collector current (30 mA), forward current (50 mA), and collector-emitter breakdown voltage (30 V).

2. Functional Equivalence: Both components operate as through-beam optical sensors with 0.125" (3.18mm) sensing distance and identical operating temperature range (-40°C ~ 85°C).

3. Physical Compatibility: Both components feature PCB mount through-hole packaging, ensuring mechanical compatibility with existing PCB layouts designed for the HOA0860-T55.

4. Compliance Status: The OPB360T51 maintains ROHS3 compliance, meeting current regulatory requirements. The original HOA0860-T55 was RoHS compliant, and the substitute exceeds this standard.

5. Product Availability: The OPB360T51 is classified as active product status with documented inventory availability, ensuring long-term supply chain continuity compared to the obsolete HOA0860-T55.

6. Regulatory Alignment: Both components share identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, maintaining consistent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the OPB360T51 directly replace the HOA0860-T55 in existing designs?

A: Yes. The OPB360T51 is electrically and mechanically compatible with the HOA0860-T55. Both components share identical sensing distance, through-beam sensing method, electrical current and voltage ratings, operating temperature range, and PCB mount through-hole packaging. No circuit modifications are required for substitution.

Q: What is the difference between transistor and phototransistor output configurations?

A: Both output configurations are transistor-based devices suitable for through-beam sensing applications. The phototransistor output of the OPB360T51 operates within the same electrical parameters as the transistor output of the HOA0860-T55, maintaining functional compatibility in circuit applications.

Q: Are there any compliance differences between the two parts?

A: The OPB360T51 carries ROHS3 compliance, which exceeds the RoHS compliance of the HOA0860-T55. Both components share identical ECCN and HTSUS classifications. The substitute meets or exceeds all regulatory requirements of the original part.

Q: What is the response time specification for the OPB360T51?

A: The response time specification for the OPB360T51 is not provided in the available technical parameters. The HOA0860-T55 specifies 15µs response time. For applications requiring specific response time verification, consult the OPB360T51 detailed datasheet.

Q: Is the OPB360T51 available in the same packaging as the HOA0860-T55?

A: Both components feature PCB mount through-hole packaging. The OPB360T51 is supplied in bulk packaging, while the HOA0860-T55 packaging type was not specified. Both are compatible with standard PCB assembly processes.

Q: Why is the HOA0860-T55 classified as obsolete?

A: The HOA0860-T55 is listed as obsolete product status, indicating it is no longer manufactured or supported by Honeywell Sensing and Productivity Solutions. The OPB360T51 is an active product with ongoing manufacturer support and supply availability.
