HOA2862-002 Equivalent & Substitute Parts Reference

Part Overview

The HOA2862-002 is an optical sensor manufactured by Honeywell Sensing and Productivity Solutions, designed as a through-beam phototransistor module with a 0.100" (2.54mm) slotted configuration. This component operates as an unamplified optical sensor for detecting object presence or absence in slot-based applications.

The HOA2862-002 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this sensor.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HOA2862-002 are identified based on strict electrical and mechanical compatibility criteria. The following parameters define acceptable substitution:

Critical Matching Parameters:

• Sensing Distance: 0.100" (2.54mm)
• Sensing Method: Through-Beam
• Output Configuration: Phototransistor
• Current - DC Forward (If) (Max): 50 mA
• Voltage - Collector Emitter Breakdown (Max): 30 V
• Type: Unamplified
• Mounting Type: Through Hole

Allowable Variations:

• Response Time: Substitute may be equal to or faster than the original
• Operating Temperature Range: Substitute range may be narrower than the original
• Package / Case: Physical form factor may differ (Module, Slotted vs. PCB Mount) provided mechanical integration is feasible
• Product Status: Active status preferred for ongoing availability
• RoHS Compliance: ROHS3 Compliant acceptable as equivalent to RoHS Compliant

The OPB847 meets all critical matching parameters and represents a valid electrical equivalent with improved response time performance and active product status.

Parameter Comparison

Engineering Selection Recommendations

OPB847 as Primary Substitute:

The OPB847 from TT Electronics/Optek Technology is electrically equivalent to the HOA2862-002 across all critical parameters: sensing distance, sensing method, output configuration, forward current rating, and breakdown voltage. The OPB847 demonstrates superior response time (12µs versus 15µs), indicating faster optical detection capability.

Product Status Advantage:

The OPB847 maintains active product status, ensuring continued availability and supply chain support. The HOA2862-002 is obsolete, making the OPB847 the preferred long-term solution for new designs or ongoing production support.

Compliance Considerations:

Both components meet RoHS requirements. The OPB847 carries ROHS3 Compliant certification, which supersedes the RoHS Compliant designation of the HOA2862-002. Both components are REACH Unaffected or equivalent, supporting regulatory compliance in industrial applications.

Mechanical Integration:

The primary difference between these components is packaging: the HOA2862-002 uses a slotted module form factor, while the OPB847 is configured for PCB mount. Mechanical integration feasibility depends on the specific application's slot geometry and PCB layout requirements. Through-hole mounting compatibility is maintained in both designs.

Operating Temperature Consideration:

The OPB847 operates within -40°C to 85°C, which is narrower than the HOA2862-002 range of -55°C to 100°C. Applications requiring operation below -40°C or above 85°C require verification against specific system requirements.

Frequently Asked Questions (FAQ)

Q: Can the OPB847 directly replace the HOA2862-002 in existing designs?

A: Electrical substitution is valid based on matched current, voltage, sensing distance, and response characteristics. Mechanical integration depends on whether the PCB mount configuration of the OPB847 is compatible with the original slotted module mounting points. Physical layout verification is required.

Q: What is the significance of the response time difference (15µs vs. 12µs)?

A: The OPB847's faster response time indicates superior optical detection speed. This represents an improvement over the original specification and does not create compatibility issues. Applications with timing-critical requirements benefit from this enhanced performance.

Q: Why is the OPB847 operating temperature range narrower than the HOA2862-002?

A: The OPB847 is specified for -40°C to 85°C operation, while the HOA2862-002 covers -55°C to 100°C. For applications operating within the OPB847 range, no limitation exists. Applications requiring extended temperature operation below -40°C or above 85°C must confirm compatibility with the OPB847's specifications or identify alternative solutions.

Q: Are both components RoHS compliant?

A: Yes. The HOA2862-002 is RoHS Compliant, and the OPB847 is ROHS3 Compliant. ROHS3 represents current regulatory compliance and is acceptable as an equivalent or superior designation.

Q: What does "Through-Beam" sensing method mean?

A: Through-beam sensing uses a light source and receiver positioned on opposite sides of a slot. An object passing through the slot interrupts the light beam, triggering detection. Both the HOA2862-002 and OPB847 operate using this principle with a 0.100" (2.54mm) slot width.

Q: Is the OPB847 suitable for high-speed applications?

A: The OPB847's 12µs response time supports applications requiring rapid optical detection. Specific application speed requirements should be compared against this specification to confirm suitability.

Q: What is the difference between "Module, Slotted" and "PCB Mount" packaging?

A: Module, Slotted refers to a standalone sensor assembly designed to mount into a mechanical slot structure. PCB Mount indicates the sensor is designed for direct soldering or insertion into a printed circuit board. The functional sensing capability is equivalent; the mounting method differs.
