HOA1883-012 Equivalent & Substitute Parts

Part Overview

The HOA1883-012 is an optical sensor manufactured by Honeywell Sensing and Productivity Solutions, classified as a through-beam phototransistor slotted module. This component features a 0.140" (3.56mm) sensing distance and unamplified output configuration. The product is currently obsolete, making identification of equivalent substitute parts essential for system maintenance, repair, and legacy equipment support. The through-hole mounting design and slotted module package are critical form factors for direct replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HOA1883-012 is determined by strict alignment of the following critical parameters:

Form Factor Requirements:

• Package type: Slotted Module
• Mounting type: Through Hole
• Sensing method: Through-Beam

Electrical Performance Parameters:

• Output configuration: Phototransistor
• Current rating: Maximum 50 mA DC forward
• Voltage rating: Minimum 30 V collector-emitter breakdown
• Response time: 15µs or faster
• Operating temperature range: -40°C to 85°C minimum

Compliance & Certification:

• ECCN classification: EAR99
• HTSUS code: 8541.49.8000
• Moisture sensitivity: MSL 1 or better

The OPB804 from onsemi meets the core form factor and functional requirements as a through-beam phototransistor slotted module with through-hole mounting. However, compliance differences exist and must be evaluated for specific applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: RoHS Compliance Difference

The HOA1883-012 is RoHS Compliant, while the OPB804 is RoHS non-compliant. This distinction is critical for applications subject to RoHS regulations, particularly in European markets and regulated industries. Systems designed with RoHS-compliant components should not substitute with non-compliant alternatives without explicit regulatory review.

Form Factor Compatibility

Both components share identical form factors: slotted module package with through-hole mounting. This ensures mechanical and positional compatibility in PCB layouts and mechanical assemblies designed for the HOA1883-012.

Functional Equivalence

Both components operate as through-beam phototransistor sensors with identical ECCN and HTSUS classifications. The OPB804 is functionally equivalent for through-beam optical sensing applications where RoHS compliance is not a requirement.

Product Status Alignment

Both components are obsolete. Substitution should be evaluated within the context of legacy system support and long-term component availability planning.

Frequently Asked Questions (FAQ)

Q: Can the OPB804 directly replace the HOA1883-012 in all applications?

A: The OPB804 provides functional and mechanical equivalence as a through-beam phototransistor slotted module. However, the RoHS compliance difference must be evaluated against application requirements. Systems requiring RoHS compliance cannot use the OPB804 as a substitute.

Q: What are the critical parameters for determining substitutability?

A: Substitutability is determined by: (1) Package type and mounting method (slotted module, through-hole), (2) Sensing method (through-beam), (3) Output type (phototransistor), (4) Electrical ratings (current, voltage, response time), and (5) Operating temperature range. Compliance certifications (RoHS, ECCN, HTSUS) must also align with application requirements.

Q: Are there electrical parameter differences between these components?

A: The provided data does not include complete electrical specifications for the OPB804 (such as maximum current, voltage ratings, or response time). Substitution decisions based on electrical performance require access to the OPB804 datasheet for detailed parameter comparison.

Q: What is the significance of the slotted module package?

A: The slotted module package defines the physical form factor with an optical slot for through-beam sensing. This package type is essential for applications requiring object detection across a defined gap. Both components use this identical package, ensuring mechanical compatibility.

Q: How does product obsolescence affect substitution?

A: Both components are obsolete, indicating discontinued manufacturing. Substitution between obsolete parts is appropriate for legacy system maintenance. However, long-term availability of either component should be verified with suppliers before committing to production use.

Q: What compliance certifications are relevant for substitution?

A: ECCN (EAR99) and HTSUS (8541.49.8000) classifications are identical, indicating equivalent export control and tariff treatment. RoHS compliance differs and is the primary regulatory distinction between these components.
