Engineering Selection Recommendations

All listed substitute parts maintain electrical and mechanical equivalence to the OPB982N11. The primary distinction between the obsolete OPB982N11 and active substitutes is regulatory compliance status. The OPB982N11 is RoHS non-compliant, while all substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements.

Selection among active substitutes should be based on inventory availability and packaging requirements. All substitute parts are manufactured by TT Electronics/Optek Technology within the Photologic® series and carry REACH Unaffected status with identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications.

Frequently Asked Questions (FAQ)

Q: Can OPB982N11 be directly replaced with any of the listed substitutes?

A: Yes. All listed substitute parts maintain identical electrical specifications (15 mA supply current, 4.75V ~ 5.25V supply voltage, 70ns response time), mechanical specifications (0.125" sensing distance, through-beam sensing method, totem pole inverted output, chassis mount configuration), and operating temperature range (-40°C ~ 70°C). Direct substitution is electrically and mechanically compatible.

Q: What is the primary difference between OPB982N11 and the substitute parts?

A: The OPB982N11 is classified as obsolete and is RoHS non-compliant. All substitute parts are active products with ROHS3 compliance, meeting current regulatory requirements for new designs and manufacturing.

Q: Are there packaging differences between the main part and substitutes?

A: The OPB982N11 is packaged in module wire leads format without specified packaging type. All substitute parts are supplied in bulk packaging. The module, wire leads configuration remains consistent across all parts.

Q: Do all substitutes have the same inventory status?

A: All substitute parts are classified as active products with new original stock available. Inventory quantities vary by part number, ranging from 830 to 69,800 pieces.

Q: Are there any compliance or certification differences?

A: All parts share identical REACH Unaffected status and ECCN/HTSUS classifications. The key compliance difference is RoHS status: OPB982N11 is non-compliant, while all substitutes are ROHS3 compliant.
