Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HOA1882-012 are identified based on strict equivalence of the following critical parameters:

Substitution Criteria:

• Sensing Method: Through-Beam (identical optical detection principle)
• Output Configuration: Phototransistor (identical transducer type)
• Mounting Type: Through Hole (identical mechanical interface)
• Package / Case: PCB Mount (identical form factor)
• Type: Unamplified (identical signal processing level)
• Current - DC Forward (If) (Max): 50 mA (identical maximum rating)
• Voltage - Collector Emitter Breakdown (Max): 30 V (identical maximum rating)
• Operating Temperature: -40°C ~ 85°C (identical thermal range)

Sensing Distance Tolerance: The HOA1882-012 operates at 0.200" (5.08mm). Substitute parts with sensing distances of 0.201" (5.1mm) and 0.205" (5.21mm) fall within acceptable mechanical and optical tolerance for slot-type sensor applications where the gap width is the primary design constraint.

Parameter Comparison

Engineering Selection Recommendations

OPB200 and OPB855 Substitution Basis:

Both OPB200 and OPB855 are manufactured by TT Electronics/Optek Technology and maintain active product status, ensuring long-term supply chain availability. Both parts satisfy all critical electrical and mechanical parameters required for direct substitution with the HOA1882-012.

Compliance Considerations:

The substitute parts carry ROHS3 compliance certification, which supersedes the RoHS compliance status of the obsolete HOA1882-012. Both substitute parts are REACH Unaffected, providing regulatory assurance for applications subject to REACH requirements.

Sensing Distance Selection:

The OPB200 (0.201" / 5.1mm) provides the closest sensing distance match to the original HOA1882-012 (0.200" / 5.08mm), with a variance of 0.001" (0.02mm). The OPB855 (0.205" / 5.21mm) introduces a variance of 0.005" (0.13mm). Selection between these two parts depends on the mechanical tolerance of the slot width in the target application. For applications with tight slot tolerances, OPB200 is the preferred choice. For applications with broader mechanical tolerances, OPB855 is acceptable.

Inventory Availability:

OPB200 maintains 2,935 units in stock. OPB855 maintains 4,782 units in stock, providing superior supply security for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can OPB200 and OPB855 be used interchangeably with HOA1882-012?

A: Both OPB200 and OPB855 meet the electrical and mechanical specifications of the HOA1882-012. Selection between them depends on the mechanical slot width tolerance of your application. The OPB200 offers closer sensing distance alignment (0.001" variance), while OPB855 introduces a 0.005" variance.

Q: What is the significance of the sensing distance difference between these parts?

A: Sensing distance determines the gap width through which the optical beam passes. The HOA1882-012 operates at 0.200" (5.08mm). OPB200 operates at 0.201" (5.1mm), and OPB855 operates at 0.205" (5.21mm). These differences are within typical mechanical tolerances for slot-type sensor applications but must be verified against your specific slot width specification.

Q: Are there any electrical performance differences I should consider?

A: All three parts share identical maximum ratings for DC forward current (50 mA) and collector-emitter breakdown voltage (30 V). The HOA1882-012 specifies a response time of 15µs; response time data is not provided for OPB200 and OPB855. If response time is a critical parameter for your application, contact the manufacturer for OPB series response time specifications.

Q: What is the difference between RoHS and ROHS3 compliance?

A: ROHS3 represents the current revision of the Restriction of Hazardous Substances directive and supersedes earlier RoHS compliance designations. ROHS3 compliance ensures the substitute parts meet current regulatory requirements for restricted substances in electrical and electronic equipment.

Q: Does the MSL rating affect substitution?

A: All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations during storage or handling. This parameter is equivalent across all parts and does not affect substitution decisions.

Q: Which substitute part should I select for new designs?

A: For new designs, either OPB200 or OPB855 is acceptable based on your mechanical slot width tolerance. OPB200 is recommended when slot width tolerance is ±0.001" or tighter. OPB855 is acceptable for applications with broader mechanical tolerances. Both parts carry active product status and superior inventory availability compared to the obsolete HOA1882-012.
