SDP8610-003 Equivalent & Substitute Parts

Part Overview

The SDP8610-003 is an optical sensor manufactured by Honeywell Sensing and Productivity Solutions, classified as a photodetector with Schmitt logic output and side-looking configuration. This component operates at 935nm wavelength and provides open collector inverter output in a radial 3-lead package. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system maintenance, repair, and legacy design support. Substitute components must maintain functional equivalence across wavelength, output type, operating temperature range, and environmental compliance specifications.

Operating Temperature Range: All substitute parts support the -40°C ~ 85°C operating temperature specification, ensuring functional performance across the same environmental conditions.

Sensor Type: All substitute parts are photo detectors with logic output capability, maintaining the same functional classification.

Package Configuration: Substitute parts utilize side-view configurations compatible with the original side-looking optical path design.

Environmental Compliance: Substitute parts meet or exceed RoHS compliance requirements and maintain MSL 1 rating, ensuring equivalent environmental qualification.

Parameter Comparison

Engineering Selection Recommendations

OPL531-OCA Selection Criteria: This substitute part is manufactured by TT Electronics/Optek Technology under the active Photologic® series. It maintains all critical electrical parameters including 935nm wavelength, open collector inverter output, and -40°C ~ 85°C operating temperature range. The component holds ROHS3 compliance status and MSL 1 rating. The 3-SIP package configuration provides side-view optical alignment equivalent to the original design. This part is recommended for applications requiring direct functional replacement with active product support and ongoing availability.

OPL551-OCA Selection Criteria: This substitute part is also manufactured by TT Electronics/Optek Technology within the active Photologic® series. It provides identical electrical specifications including 935nm wavelength, open collector inverter output, and matching operating temperature range. ROHS3 compliance and MSL 1 rating ensure equivalent environmental qualification. The side-view package configuration maintains optical path compatibility. This part is recommended for applications where package form factor flexibility exists and active product lifecycle support is required.

Product Status Advantage: Both substitute parts carry active product status, ensuring continued manufacturing availability, technical support, and supply chain reliability compared to the obsolete SDP8610-003.

Frequently Asked Questions (FAQ)

Q: What determines if OPL531-OCA or OPL551-OCA can replace SDP8610-003?

A: Substitution is based on matching wavelength (935nm), output type (open collector inverter), operating temperature range (-40°C ~ 85°C), sensor type (photo detector with logic output), and side-view package configuration. Both substitute parts meet all these criteria.

Q: Are there differences in package configuration between the substitute parts?

A: Yes. OPL531-OCA uses a 3-SIP package, while OPL551-OCA uses a side-view configuration. The original SDP8610-003 uses a radial 3-lead side-view package. Physical mounting and PCB layout compatibility must be verified for each application.

Q: Do the substitute parts have the same RoHS compliance level?

A: The SDP8610-003 is RoHS Compliant. Both OPL531-OCA and OPL551-OCA are ROHS3 Compliant, which represents an updated compliance standard. Both meet or exceed the original compliance requirement.

Q: What is the moisture sensitivity level for substitute parts?

A: Both OPL531-OCA and OPL551-OCA maintain MSL 1 (Unlimited) rating, identical to the original SDP8610-003. This indicates no moisture sensitivity restrictions for storage or handling.

Q: Can I use either substitute part interchangeably?

A: Both parts meet the same electrical and environmental specifications. Selection between OPL531-OCA and OPL551-OCA depends on package form factor compatibility with your specific PCB layout and mechanical mounting requirements.

Q: What is the advantage of using active product substitutes?

A: OPL531-OCA and OPL551-OCA are active products with ongoing manufacturing support, ensuring long-term availability, technical documentation access, and supply chain reliability compared to the obsolete SDP8610-003.
