Substitute Part Grouping Explanation

Substitution of the OPS665 is based on strict equivalence across the following critical parameters:

• Sensing Method: Through-Beam operation
• Output Configuration: Phototransistor
• Package / Case: T-1 form factor
• Mounting Type: Through Hole
• Type: Unamplified
• Current - DC Forward (If) (Max): 50 mA maximum
• Voltage - Collector Emitter Breakdown (Max): 30 V maximum
• Operating Temperature Range: -40°C ~ 100°C
• Compliance Standards: ROHS3 Compliant, REACH Unaffected

The OPS666 meets all substitution criteria as a direct equivalent manufactured by the same supplier with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The OPS666 is the direct substitute for the obsolete OPS665. Both components share identical electrical ratings, mechanical specifications, and compliance certifications. The OPS666 maintains active product status with the same manufacturer, ensuring long-term availability and supply chain continuity. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The transition from OPS665 to OPS666 requires no circuit modifications or design changes, as all functional parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can OPS666 be used as a direct replacement for OPS665 in existing designs?

A: Yes. The OPS666 is electrically and mechanically equivalent to the OPS665 across all specified parameters. No circuit modifications are required.

Q: What is the primary reason for substituting OPS665 with OPS666?

A: The OPS665 is obsolete. The OPS666 is the active equivalent from the same manufacturer with identical specifications.

Q: Are the T-1 packages of both parts physically interchangeable?

A: Yes. Both components use T-1 through-hole packaging and are mechanically interchangeable in PCB designs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both OPS665 and OPS666 are ROHS3 compliant and REACH unaffected.

Q: Is there a difference in maximum collector current between these parts?

A: The OPS666 specifies a maximum collector current (Ic) of 100 µA, which is an additional parameter not listed for the OPS665. This does not affect substitution compatibility.
