Frequently Asked Questions (FAQ)

Q: Can the OPB848 be used as a direct replacement for the HOA1872-011?

A: Yes. The OPB848 meets all critical substitution criteria: identical sensing distance (0.100"), through-beam sensing method, phototransistor output configuration, maximum forward current (50 mA), maximum collector-emitter breakdown voltage (30 V), operating temperature range (-40°C ~ 85°C), and PCB mount through-hole packaging. Both components are unamplified optical sensors with equivalent mechanical and electrical specifications.

Q: What is the primary difference between these two parts?

A: The OPB848 exhibits a faster response time of 12µs compared to the HOA1872-011 at 15µs. This represents improved switching performance. The OPB848 is also an active product with current availability, whereas the HOA1872-011 is obsolete.

Q: Are there any compliance or regulatory differences?

A: Both components maintain equivalent compliance status. The HOA1872-011 is RoHS Compliant, while the OPB848 is ROHS3 Compliant. Both are REACH Unaffected and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. No regulatory barriers exist for substitution.

Q: Does the PCB mount packaging differ between these components?

A: No. Both the HOA1872-011 and OPB848 utilize identical through-hole PCB mount packaging. No mechanical redesign or board layout modification is required for substitution.

Q: What is the current inventory status for the OPB848?

A: The OPB848 is listed as an active product with 1280 pieces in new original stock, ensuring supply availability for immediate procurement.
