Substitute Part Grouping Explanation

Substitution for the OPB483N11Z is determined by strict equivalence across the following critical parameters:

Sensing distance: 0.125" (3.18mm)
Sensing method: Through-beam
Output configuration: NPN open collector, inverted
Supply voltage range: 4.5V ~ 16V
Supply current: 7.5 mA
Response time: 50ns
Operating temperature range: -40°C ~ 85°C
RoHS and regulatory compliance: ROHS3 compliant, REACH unaffected, EAR99 classification

Substitute parts are grouped into two categories based on mounting configuration:

Wire Lead Module Substitutes (Chassis Mount): OPB483L11Z, OPB483P11Z, OPB493T11Z — maintain identical wire lead packaging and chassis mount configuration as the original OPB483N11Z.

PCB Mount Substitutes (Through Hole): OPB463N11, OPB473N11 — provide functional equivalence with alternative through-hole PCB mount packaging for applications requiring board-level integration.

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and functional equivalence to the OPB483N11Z across all specified parameters. Selection between wire lead and PCB mount variants depends solely on mechanical integration requirements:

For applications requiring wire lead connectivity and chassis mounting, OPB483L11Z, OPB483P11Z, and OPB493T11Z provide direct functional replacement with active product status and full ROHS3 compliance.

For applications requiring PCB-level integration through through-hole mounting, OPB463N11 and OPB473N11 deliver equivalent electrical performance with active product status and full regulatory compliance.

All substitute parts carry ROHS3 compliance, REACH unaffected status, and EAR99 export classification, matching the regulatory profile of the original OPB483N11Z.

Frequently Asked Questions (FAQ)

Q: Can OPB483N11Z be directly replaced with OPB483L11Z or OPB483P11Z?

A: Yes. OPB483L11Z and OPB483P11Z are functionally equivalent with identical electrical specifications, sensing distance, output configuration, and wire lead packaging. The primary difference is product status: OPB483N11Z is obsolete while OPB483L11Z and OPB483P11Z are active production parts.

Q: What is the difference between wire lead and PCB mount variants?

A: Wire lead variants (OPB483L11Z, OPB483P11Z, OPB493T11Z) feature chassis mount configuration with wire leads for direct circuit connection. PCB mount variants (OPB463N11, OPB473N11) feature through-hole mounting for direct PCB integration. Electrical performance is identical across both mounting types.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the regulatory compliance of the original OPB483N11Z.

Q: Which substitute part should be selected for new designs?

A: For new designs requiring wire lead connectivity, OPB483L11Z or OPB483P11Z are recommended as active production parts with full electrical equivalence. For PCB-integrated designs, OPB463N11 or OPB473N11 provide equivalent functionality with through-hole mounting.

Q: Is there a difference in response time between substitute parts?

A: No. All substitute parts maintain the 50ns response time specification of the original OPB483N11Z.
