Key Parameters

Substitute Part Grouping Explanation

Substitution for the OPB490L11Z is determined by strict equivalence across the following electrical and mechanical parameters:

• Sensing distance: 0.125" (3.18mm)
• Sensing method: Through-Beam
• Output configuration: Pull-Up Resistor, Buffer
• Supply voltage range: 4.5V ~ 16V
• Supply current: 7.5 mA
• Response time: 50ns
• Operating temperature range: -40°C ~ 85°C
• RoHS3 compliance and REACH unaffected status

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

Category 1: Chassis Mount, Module Wire Leads — Direct functional equivalents with identical mounting and packaging. These parts maintain the same form factor and installation method as the original OPB490L11Z.

Category 2: Through Hole PCB Mount — Functional equivalents with different mounting configuration. These parts provide the same electrical performance but require different installation methodology.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and functional equivalence to the OPB490L11Z across all specified parameters. Selection between substitutes is determined by mounting requirements and product availability status.

For applications requiring chassis mount configuration with wire leads, OPB490P11Z, OPB490T11Z, OPB480L11Z, and OPB480T11Z are direct substitutes with active product status. These parts are manufactured by the same supplier and carry identical electrical specifications, supply voltage range, current draw, response time, and operating temperature range.

For applications permitting PCB mount configuration, OPB460T11 provides functional equivalence with active product status. This part differs only in mounting type and package configuration while maintaining all electrical performance parameters.

All substitute parts carry ROHS3 compliance and REACH unaffected status, consistent with the original OPB490L11Z specification.

Frequently Asked Questions (FAQ)

Q: Can OPB490P11Z and OPB490T11Z be used interchangeably with OPB490L11Z?

A: Yes. Both parts are active-status equivalents with identical electrical specifications, sensing distance, output configuration, supply voltage range, current draw, response time, and operating temperature range. The primary difference is packaging designation within the same module wire lead form factor.

Q: What is the difference between OPB480 series and OPB490 series substitutes?

A: Both series maintain identical electrical and functional parameters for the OPB490L11Z. The difference is in the base product number designation. All listed OPB480 and OPB490 variants provide equivalent performance for through-beam optical sensing at 0.125" (3.18mm) distance.

Q: Can OPB460T11 replace OPB490L11Z in existing designs?

A: OPB460T11 provides electrical and functional equivalence but requires design modification. The primary difference is mounting configuration: OPB460T11 uses through-hole PCB mount, while OPB490L11Z uses chassis mount with wire leads. PCB layout and mechanical mounting must be adapted accordingly.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance and REACH unaffected status, matching the original OPB490L11Z specification.

Q: What parameters determine substitution eligibility for optical sensors in this category?

A: Substitution is based on equivalence across sensing distance, sensing method, output configuration, supply voltage range, supply current, response time, operating temperature range, and compliance certifications. Mounting type and package configuration may differ if application design permits.
