Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SDP8601-001 is determined by strict alignment of the following critical parameters:

Wavelength Matching: The substitute must operate at 935nm to ensure compatibility with existing optical system design and infrared transmission characteristics.

Output Type Compatibility: Open collector logic output is mandatory to maintain electrical interface compatibility with existing circuit designs and signal conditioning requirements.

Functional Classification: The substitute must be classified as a photo detector with logic output to preserve the integrated detection and signal processing functionality.

Operating Temperature Range: The substitute must support the full -40°C to 85°C operating temperature specification to ensure reliability across the intended application environment.

Package and Lead Configuration: While the SDP8601-001 uses a radial 3-lead side view package and the substitute uses a 3-SIP side view package, both configurations are side-looking designs with three electrical connections, permitting functional substitution with appropriate mechanical adaptation.

Environmental and Compliance Standards: RoHS compliance and MSL Level 1 rating ensure the substitute meets current regulatory requirements and storage/handling standards equivalent to the original component.

Parameter Comparison

Engineering Selection Recommendations

The OPL562-OC from TT Electronics/Optek Technology qualifies as a direct functional substitute for the obsolete SDP8601-001 based on parameter alignment across all critical electrical and environmental specifications.

Product Status Consideration: The OPL562-OC maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete SDP8601-001.

Compliance Alignment: Both components meet RoHS requirements. The OPL562-OC carries ROHS3 compliance, representing current regulatory standards. Both components maintain MSL Level 1 rating, indicating equivalent moisture handling and storage requirements.

Electrical Equivalence: Identical wavelength (935nm), output type (open collector), and operating temperature range (-40°C to 85°C) confirm electrical interface compatibility.

Package Consideration: The SDP8601-001 uses radial 3-lead packaging while the OPL562-OC uses 3-SIP packaging. Both are side-view configurations with three electrical connections. Physical mounting adaptation may be required depending on circuit board layout and mechanical constraints.

Frequently Asked Questions (FAQ)

Q: Can the OPL562-OC directly replace the SDP8601-001 without circuit modification?

A: Electrical interface compatibility is confirmed across all specified parameters. Physical mounting may require adaptation due to package configuration differences (radial versus 3-SIP). Verify mechanical fit within the existing assembly before implementation.

Q: What is the significance of the 935nm wavelength specification?

A: The 935nm wavelength is a near-infrared specification that determines optical transmission characteristics and system compatibility. Substitutes must operate at this identical wavelength to function within the existing optical path and receiver design.

Q: Why is open collector output type critical for substitution?

A: Open collector output provides a specific electrical interface for logic signal transmission. This output type must be preserved to maintain compatibility with downstream signal conditioning and logic circuits.

Q: Does the package difference between radial and 3-SIP affect electrical performance?

A: Package configuration affects physical mounting and spatial requirements but does not alter electrical performance. Both radial and 3-SIP packages with three leads can deliver equivalent electrical functionality when properly integrated into the circuit.

Q: Is the OPL562-OC suitable for applications requiring the full -40°C to 85°C temperature range?

A: Yes. The OPL562-OC is specified for -40°C to 85°C operating temperature, matching the SDP8601-001 requirement and ensuring equivalent thermal performance across the intended application environment.

Q: What does MSL Level 1 (Unlimited) mean for component handling?

A: MSL Level 1 indicates the component has unlimited shelf life and does not require special moisture control during storage or handling. Both the SDP8601-001 and OPL562-OC carry this rating, ensuring equivalent storage and logistics requirements.
