Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HOA1882-011 are identified based on strict electrical and mechanical compatibility criteria. The primary substitution logic is based on the following allowed parameters:

Critical Matching Parameters:

• Sensing method: Through-Beam
• Output configuration: Phototransistor
• Mounting type: Through Hole
• Package type: PCB Mount
• Operating temperature range: -40°C ~ 85°C
• Voltage - Collector Emitter Breakdown: 30 V

Allowable Variation Parameters:

• Sensing distance: Within 0.005" (0.127mm) tolerance
• Current ratings: Equal to or greater than the original specification
• Response time: Not specified for substitute, therefore not a limiting factor

The OPB855 from TT Electronics/Optek Technology meets these substitution criteria with a sensing distance of 0.205" (5.21mm), which falls within acceptable mechanical tolerance for slot-type optical sensor applications.

Engineering Selection Recommendations

The OPB855 is a direct functional substitute for the HOA1882-011 based on the following engineering criteria:

Product Status Consideration: The HOA1882-011 is classified as obsolete, making the OPB855 (active product status) the appropriate selection for new designs and ongoing production requirements.

Compliance Alignment: Both components maintain RoHS compliance. The OPB855 carries ROHS3 Compliant status, which represents current regulatory alignment. Both components are MSL Level 1, indicating unlimited shelf life without moisture sensitivity constraints.

Electrical Performance: The OPB855 demonstrates superior electrical performance with maximum collector current of 30 mA compared to 1.8 mA for the HOA1882-011. This enhanced capability ensures the substitute part operates within safe margins in existing circuit designs without requiring circuit modifications.

Mechanical Compatibility: The sensing distance variance of 0.005" (0.127mm) between the two components is within standard mechanical tolerance for slot-type optical sensor applications. Both components utilize identical through-hole PCB mount configurations, ensuring direct mechanical interchangeability.

Regulatory and Supply Considerations: The OPB855 carries REACH Unaffected status and maintains EAR99 export classification, consistent with the original component. Current inventory availability of 4782 units ensures supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the OPB855 be used as a direct replacement for the HOA1882-011 without circuit modifications?

A: Yes. The OPB855 is electrically and mechanically compatible with the HOA1882-011. Both components share identical voltage ratings, operating temperature ranges, and mounting configurations. The enhanced current ratings of the OPB855 do not require circuit modifications and operate safely within existing designs.

Q: What is the significance of the 0.005" (0.127mm) sensing distance difference between the two parts?

A: The sensing distance variance falls within standard mechanical tolerance for slot-type optical sensor applications. Both components are designed for through-beam sensing in slot configurations where this tolerance range is accommodated by standard mechanical design practices.

Q: Are there any compliance or regulatory differences between the HOA1882-011 and OPB855?

A: Both components maintain RoHS compliance and carry EAR99 export classification. The OPB855 carries ROHS3 Compliant status, representing current regulatory standards. Both components are MSL Level 1, indicating identical moisture sensitivity handling requirements.

Q: Why is the HOA1882-011 classified as obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The OPB855 remains in active production status, making it the appropriate selection for applications requiring long-term component availability and supply continuity.

Q: What packaging considerations apply to the OPB855?

A: The OPB855 is supplied in bulk packaging, consistent with the PCB mount configuration. Both components utilize through-hole mounting, ensuring identical PCB assembly processes and handling procedures.

Q: Are response time specifications comparable between the two components?

A: The HOA1882-011 specifies a response time of 15µs. Response time data is not provided for the OPB855 in the available specifications. Both components are designed for through-beam optical sensing applications where response time performance is suitable for standard industrial sensing applications.
