Substitute Part Grouping Explanation

The OPB850-1Z qualifies as a direct substitute based on the following criteria:

Electrical Compatibility:

• Identical sensing method (Optical Flag)
• Identical output configuration (Transistor, Base-Emitter Resistor)
• Matching current specifications (If Max: 50 mA, Ic Max: 20 mA)
• Matching voltage rating (Collector Emitter Breakdown: 24 V)
• Identical operating temperature range (-20°C ~ 75°C)

Mechanical Compatibility:

• Identical mounting type (Snap-In)
• Identical package configuration (Module, Pre-Wired)
• Identical sensor type (Unamplified)

Environmental Compliance:

• Identical MSL rating (1 - Unlimited)
• Identical REACH status (REACH Unaffected)
• Identical ECCN classification (EAR99)

Parameter Comparison

Engineering Selection Recommendations

The OPB850-1Z is the direct equivalent for the obsolete OPB850-1. Both components share identical electrical and mechanical specifications across all critical parameters: sensing method, output configuration, current ratings, voltage ratings, operating temperature range, mounting type, and package configuration.

The primary distinction is product status and regulatory compliance. The OPB850-1Z is currently in active production status, whereas the OPB850-1 is obsolete. The OPB850-1Z achieves ROHS3 compliance, whereas the original OPB850-1 is RoHS non-compliant. Both maintain identical REACH and ECCN classifications.

For new designs or component replacement in existing applications, the OPB850-1Z provides functional and electrical equivalence with the advantage of current availability and improved regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the OPB850-1Z directly replace the OPB850-1 in existing applications?

A: Yes. The OPB850-1Z maintains identical electrical specifications (current, voltage, temperature range) and mechanical configuration (snap-in mounting, pre-wired module package). No circuit modifications are required.

Q: What is the primary reason to transition from OPB850-1 to OPB850-1Z?

A: The OPB850-1 is obsolete with limited inventory availability. The OPB850-1Z is the active production equivalent from the same manufacturer, offering identical performance with current supply chain access.

Q: Are there packaging differences between these parts?

A: No. Both components use identical packaging: Module, Pre-Wired configuration with snap-in mounting type.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance status reflects manufacturing process and material composition standards, not electrical or functional performance. Both components deliver identical electrical characteristics.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by: sensing method (Optical Flag), output configuration (Transistor, Base-Emitter Resistor), current ratings (If Max 50 mA, Ic Max 20 mA), voltage rating (24 V), operating temperature range (-20°C to 75°C), and mounting type (Snap-In).
