Substitute Part Grouping Explanation

Substitute parts for the OPB950 are identified based on strict equivalence across the following critical parameters:

• Sensing distance: 0.201" (5.1mm)
• Sensing method: Through-beam optical detection
• Output configuration: NPN open collector with inverted logic
• Mounting type: Snap-in PCB mount
• Supply voltage range: 4.75V ~ 5.25V
• Operating temperature range: -40°C ~ 85°C
• Package type: PCB mount form factor

The OPB950Z is classified as a direct substitute because it maintains identical specifications across all electrical and mechanical parameters while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The OPB950Z is the direct substitute for the obsolete OPB950. Both parts maintain identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility. The OPB950Z offers the advantage of active product status with ROHS3 compliance, making it the preferred selection for new designs and system replacements. Both parts share identical supply voltage requirements, operating temperature ranges, sensing characteristics, and PCB mount form factors. Selection between these parts should be based on product availability and compliance requirements for the target application.
