HOA0865-T55 Equivalent & Substitute Parts

Part Overview

The HOA0865-T55 is an optical sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for through-beam sensing applications with a 0.125" (3.18mm) sensing distance. This component features transistor output configuration and is mounted on PCB through-hole connections. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations where legacy component specifications must be maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HOA0865-T55 is determined by strict alignment with the following critical parameters:

Primary Substitution Criteria:

• Sensing distance: 0.125" (3.18mm)
• Sensing method: Through-beam
• Output configuration: Transistor or phototransistor
• Maximum collector current: 30 mA
• Maximum collector-emitter breakdown voltage: 30 V
• Operating temperature range: -40°C ~ 85°C
• Mounting type: Through hole
• Package type: PCB mount

Substitute parts must maintain compatibility across all electrical specifications and physical mounting requirements. Output configuration variants (transistor vs. phototransistor) are acceptable provided all electrical parameters remain within specified limits.

Parameter Comparison

Engineering Selection Recommendations

OPB360T51 (TT Electronics/Optek Technology):

The OPB360T51 demonstrates full electrical parameter compatibility with the HOA0865-T55 across all specified dimensions: sensing distance, collector current limits, breakdown voltage, and operating temperature range. This part maintains active product status, ensuring ongoing availability and manufacturer support. The component carries ROHS3 compliance certification, exceeding the RoHS compliance level of the original part. Physical mounting configuration (through-hole PCB mount) is identical. The phototransistor output configuration is functionally equivalent to the transistor output of the HOA0865-T55 within the specified electrical operating envelope.

OPB865T55 (onsemi):

The OPB865T55 shares the same base product number designation (OPB865) as the HOA0865-T55, indicating design lineage. However, this part is classified as obsolete and carries RoHS non-compliant status. The package configuration (Module, PC Pins, Slot Type) differs from the PCB mount specification of the original part. Critical electrical parameters including sensing distance, collector current, and breakdown voltage are not provided in available documentation, preventing full parameter verification. This part is not recommended as a primary substitute due to compliance status and incomplete specification data.

Frequently Asked Questions (FAQ)

Q: Can the OPB360T51 directly replace the HOA0865-T55 in existing designs?

A: The OPB360T51 meets all specified electrical parameters (sensing distance, collector current, breakdown voltage, operating temperature) and maintains identical through-hole PCB mount configuration. The phototransistor output is functionally compatible within the electrical specifications provided. Physical board layout verification is required to confirm pin-to-pin compatibility.

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

A: Both configurations are output types for optical sensors. The distinction lies in internal circuitry, but within the specified electrical parameters (maximum collector current of 30 mA, breakdown voltage of 30 V, operating temperature -40°C to 85°C), both are functionally equivalent for through-beam sensing applications at 0.125" (3.18mm) distance.

Q: Why is the OPB360T51 preferred over the OPB865T55?

A: The OPB360T51 is active product status with ROHS3 compliance certification, ensuring manufacturer support and regulatory alignment. Complete electrical specifications are documented. The OPB865T55 is obsolete with RoHS non-compliant status and incomplete parameter documentation, limiting its suitability for new implementations.

Q: Are there any package or pinout differences between these parts?

A: The HOA0865-T55 and OPB360T51 both specify PCB mount through-hole configuration. The OPB865T55 uses Module, PC Pins, Slot Type packaging, which differs from the original specification. Physical pinout verification against schematic requirements is necessary before implementation.

Q: What compliance certifications should be considered for substitute selection?

A: The HOA0865-T55 carries RoHS Compliant status. The OPB360T51 exceeds this with ROHS3 Compliant certification. The OPB865T55 is RoHS non-compliant. For applications requiring regulatory compliance, the OPB360T51 is the appropriate selection.
