Key Parameters

Substitute Part Grouping Explanation

Substitution of the SDP8610-002 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Wavelength: 935nm infrared detection band
• Sensor Type: Photo Detector with integrated logic output
• Output Type: Open Collector Inverter configuration
• Viewing Geometry: Side View orientation
• Operating Temperature Range: -40°C to 85°C minimum requirement
• Lead Configuration: 3-lead radial package

The OPL551-OCA from TT Electronics/Optek Technology satisfies all critical parameters and is identified as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The OPL551-OCA is the identified substitute for the obsolete SDP8610-002. Selection is based on the following factors:

Compliance Alignment: Both components maintain RoHS compliance status. The OPL551-OCA carries ROHS3 certification, which supersedes the RoHS Compliant designation of the original part, ensuring continued regulatory compliance in new applications.

Product Status: The OPL551-OCA maintains active product status with documented inventory availability (970 pcs), whereas the SDP8610-002 is obsolete. This status difference necessitates substitution for ongoing procurement and system support.

Electrical and Mechanical Equivalence: All critical parameters—wavelength, output configuration, operating temperature range, and lead count—are identical between the two components, enabling direct functional substitution in circuit designs.

Packaging Consideration: The OPL551-OCA is supplied in bulk packaging, whereas original packaging specifications for the SDP8610-002 were not provided. Verification of mechanical fit and lead spacing is required during physical integration.

Frequently Asked Questions (FAQ)

Q: Can the OPL551-OCA directly replace the SDP8610-002 in existing designs?

A: Yes. Both components share identical electrical specifications: 935nm wavelength, open collector inverter output, side-view geometry, and -40°C to 85°C operating temperature range. Physical lead configuration and spacing must be verified for mechanical compatibility.

Q: What is the significance of the product status difference?

A: The SDP8610-002 is classified as obsolete, indicating discontinued manufacturing and limited availability. The OPL551-OCA is active production, ensuring long-term supply chain reliability and continued manufacturer support.

Q: Are there compliance differences between these components?

A: Both components are RoHS compliant. The OPL551-OCA carries ROHS3 certification, which represents current regulatory standards. The OPL551-OCA is also REACH Unaffected, providing additional regulatory clarity for European applications.

Q: What parameters must remain constant for substitution?

A: Wavelength (935nm), sensor type (photo detector with logic output), output configuration (open collector inverter), viewing angle (side view), and operating temperature range (-40°C to 85°C) must all match. Deviation in any of these parameters invalidates substitution.

Q: Does the bulk packaging of the OPL551-OCA affect its use?

A: Bulk packaging refers to supply format only and does not affect component functionality. Mechanical package type (radial, 3-lead, side-view) remains consistent with the original specification.
