Key Parameters

Substitute Part Grouping Explanation

Substitution of the OP132W is determined by strict equivalence across the following critical parameters:

• Wavelength: 935nm (exact match required)
• Maximum Forward Current: 100mA (exact match required)
• Forward Voltage: 1.75V typical (exact match required)
• Viewing Angle: 50° (exact match required)
• Package Type: TO-46-2 Metal Can (exact match required)
• Operating Temperature Range: -65°C ~ 125°C (exact match required)

The OP133W qualifies as a direct substitute based on identical electrical and mechanical specifications across all critical parameters. The primary distinction between these parts is the radiant intensity specification and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The OP133W is the direct functional equivalent for OP132W replacement applications. Both components share identical electrical characteristics, mechanical packaging, and thermal operating specifications. The OP133W offers the advantage of active product status, ensuring continued availability and manufacturing support. Both parts maintain ROHS3 compliance and are unaffected by REACH regulations, satisfying environmental and regulatory requirements for industrial and commercial applications.

The OP133W exhibits a higher radiant intensity specification (5mW/cm² versus 4mW/cm²) at the same operating current, providing enhanced optical output while maintaining all other electrical and mechanical parameters. This characteristic makes the OP133W suitable for direct substitution in existing OP132W designs without circuit modification.
