Key Parameters

Substitute Part Grouping Explanation

Substitution for the OPB482N11Z is determined by strict equivalence across the following critical parameters:

• Sensing distance: 0.125" (3.18mm)
• Sensing method: Through-beam
• Output configuration: Pull-up resistor, inverted logic
• Supply voltage range: 4.5V ~ 16V
• Supply current: 7.5 mA
• Response time: 50ns
• Operating temperature range: -40°C ~ 85°C
• Series: Photologic®

Substitute parts must maintain identical electrical and optical performance characteristics. Mounting type differences (chassis mount wire leads versus PCB mount) represent distinct form factors but do not affect core sensor functionality when electrical parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain electrical and optical equivalence to the OPB482N11Z across all specified parameters. Selection between substitutes depends on form factor requirements and product lifecycle status:

OPB492T11Z and OPB492L11Z are direct functional equivalents with identical chassis mount wire lead packaging. Both are active products, ensuring long-term availability and supply chain continuity. These parts are recommended for applications requiring the same mechanical form factor as the original OPB482N11Z.

OPB472N11 provides electrical and optical equivalence but uses through-hole PCB mount packaging instead of chassis mount wire leads. This part is suitable for applications where PCB integration is preferred over chassis mounting. OPB472N11 is an active product with established supply availability.

All substitute parts carry ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original part.

Frequently Asked Questions (FAQ)

Q: Can OPB472N11 replace OPB482N11Z in existing designs?

A: OPB472N11 provides identical electrical and optical performance but uses through-hole PCB mount packaging instead of chassis mount wire leads. Mechanical integration differs; circuit-level functionality is equivalent. Design modifications to accommodate the different mounting type are required.

Q: What is the difference between OPB492T11Z and OPB492L11Z?

A: Both parts are functionally equivalent with identical electrical specifications, sensing distance, output configuration, and operating parameters. Both use chassis mount wire lead packaging matching the OPB482N11Z form factor. Both are active products. Selection between them depends on specific packaging or inventory requirements.

Q: Why is OPB482N11Z classified as obsolete?

A: The OPB482N11Z is no longer in active production. Substitute parts OPB492T11Z and OPB492L11Z provide identical functionality and are actively manufactured, ensuring continued availability for system support and new designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. OPB472N11, OPB492T11Z, and OPB492L11Z are all ROHS3 compliant, matching the regulatory status of the original OPB482N11Z.

Q: What mounting considerations apply when selecting a substitute?

A: OPB482N11Z, OPB492T11Z, and OPB492L11Z use chassis mount wire leads and are mechanically interchangeable. OPB472N11 uses through-hole PCB mount and requires different mechanical integration. Electrical performance is identical across all substitutes.
