Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OPB983P11Z are qualified based on strict parameter matching across all critical electrical and mechanical specifications. All substitute parts maintain identical values for the following parameters:

• Sensing distance: 0.125" (3.18mm)
• Sensing method: Through-beam
• Output configuration: NPN open collector, inverted
• Supply voltage range: 4.75V ~ 5.25V
• Supply current: 15 mA
• Response time: 70ns
• Operating temperature range: -40°C ~ 70°C
• Mounting type: Chassis mount
• Package type: Module with wire leads
• Compliance certifications: ROHS3, REACH Unaffected, EAR99

Substitution is valid across all listed part numbers because they share identical functional and physical characteristics. Differences in base product numbers (OPB933, OPB943, OPB983, OPB993) and suffix designations reflect manufacturing variants and packaging configurations that do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active production components with ROHS3 compliance and REACH unaffected status. Selection between OPB983P11Z and its substitutes should be based on inventory availability and lead time requirements. OPB983T51Z offers the highest inventory level at 20,199 units, providing optimal supply chain flexibility. OPB933W51Z, OPB983P51Z, and OPB983L51Z maintain substantial stock levels above 1,900 units. All parts carry identical electrical specifications, mechanical mounting configurations, and environmental operating ranges, ensuring direct functional equivalence in circuit design applications.

Frequently Asked Questions (FAQ)

Q: Can OPB983P11Z be directly replaced with OPB983T51Z? A: Yes. Both parts share identical electrical specifications, output configuration, supply voltage and current requirements, response time, operating temperature range, and mechanical mounting type. Direct substitution is valid without circuit modification.

Q: What determines if a part is a valid substitute for OPB983P11Z? A: Valid substitutes must maintain identical sensing distance (0.125"), sensing method (through-beam), output configuration (NPN open collector inverted), supply voltage (4.75V ~ 5.25V), supply current (15 mA), response time (70ns), operating temperature range (-40°C ~ 70°C), and mounting type (chassis mount). All listed parts meet these criteria.

Q: Are there differences in package configuration among the substitute parts? A: All substitute parts use identical package type: module with wire leads. Suffix designations in part numbers reflect internal manufacturing variants that do not affect external mechanical or electrical characteristics.

Q: Do all substitute parts have the same compliance certifications? A: Yes. All listed parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: Which substitute part has the best availability? A: OPB983T51Z maintains the highest inventory at 20,199 units in stock, followed by OPB983P51Z at 2,108 units and OPB983L51Z at 1,900 units.

Q: Can I use these parts interchangeably in existing circuit designs? A: Yes. All substitute parts are electrically and mechanically equivalent to OPB983P11Z. No circuit redesign or component repositioning is required for substitution.
