Frequently Asked Questions (FAQ)

Q: Can the OPB848 directly replace the LTH-306-09 without circuit board modification?

A: The OPB848 maintains through-hole mounting compatibility. However, the transition from a module-based PC pin interface to a PCB mount configuration may require footprint verification and potential layout adjustments depending on the original circuit board design.

Q: What are the key electrical differences between these components?

A: The OPB848 provides specified electrical parameters including 50 mA maximum DC forward current, 30 V collector-emitter breakdown voltage, and 12µs response time. The LTH-306-09 specifications for these parameters are not provided in the available documentation.

Q: Are there any environmental or compliance concerns with this substitution?

A: Both components share MSL 1 (Unlimited) ratings and EAR99 export classification. The OPB848 additionally carries ROHS3 Compliance and REACH Unaffected status, indicating alignment with current environmental regulations.

Q: What is the sensing distance specification for the OPB848?

A: The OPB848 is specified for 0.100" (2.54mm) sensing distance with through-beam sensing method and phototransistor output configuration.

Q: Is the OPB848 available in the same packaging as the LTH-306-09?

A: The OPB848 is supplied in bulk packaging, whereas the LTH-306-09 packaging specification is not provided. Packaging format should be confirmed with the component supplier for procurement purposes.
