Key Parameters

Substitute Part Grouping Explanation

Substitution of the SDP8601-003 is determined by strict alignment of the following critical parameters:

Wavelength Matching: All substitute parts must operate at 935nm to ensure compatibility with existing optical system design and infrared source specifications.

Output Configuration: Open collector logic output is mandatory for direct integration with existing control circuits and signal processing stages.

Functional Classification: Photo detector with integrated logic output capability is required to maintain system-level functionality.

Operating Temperature Range: Substitute parts must support the full -40°C to 85°C operating envelope to ensure reliability across specified environmental conditions.

Side-View Package Orientation: The side-looking configuration is a mechanical requirement for optical alignment and mounting within the host system.

Compliance Standards: RoHS compliance status ensures regulatory alignment and material composition compatibility.

The substitute parts OPL530-OC and OPL562-OC, both manufactured by TT Electronics/Optek Technology, satisfy all these criteria while offering active product status and enhanced availability.

Parameter Comparison

Engineering Selection Recommendations

OPL530-OC and OPL562-OC are functionally equivalent substitutes for the obsolete SDP8601-003. Both alternatives are manufactured by TT Electronics/Optek Technology under the Photologic® series and maintain active product status, ensuring long-term availability and supply chain continuity.

Both substitute parts satisfy all critical electrical and environmental parameters: 935nm wavelength operation, open collector logic output, -40°C to 85°C operating temperature range, and equivalent moisture sensitivity classification. Both are ROHS3 compliant, exceeding the RoHS compliance requirement of the original part.

The primary distinction between the SDP8601-003 and its substitutes is the package configuration: the original uses a radial 3-lead format, while OPL530-OC and OPL562-OC employ 3-SIP (Single In-line Package) configuration. This difference requires mechanical re-evaluation of mounting and PCB layout compatibility within the host system.

Selection between OPL530-OC and OPL562-OC should be based on mechanical fit, available inventory, and specific application requirements, as both parts are electrically and functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can OPL530-OC and OPL562-OC be used interchangeably with SDP8601-003?

A: Both parts satisfy the electrical and environmental specifications of the SDP8601-003. However, the package configuration differs: SDP8601-003 uses radial 3-lead format while OPL530-OC and OPL562-OC use 3-SIP format. Mechanical compatibility with existing mounting and PCB layout must be verified before implementation.

Q: What is the difference between OPL530-OC and OPL562-OC?

A: Both parts are functionally equivalent 935nm photo detectors with open collector logic output, identical operating temperature ranges, and equivalent compliance certifications. Both are manufactured by TT Electronics/Optek Technology under the Photologic® series. Selection should be based on mechanical fit, availability, and application-specific requirements.

Q: Are the substitute parts RoHS compliant?

A: Yes. OPL530-OC and OPL562-OC are ROHS3 compliant, which exceeds the RoHS compliance requirement of the original SDP8601-003.

Q: What is the operating temperature range for these optical sensors?

A: All three parts—SDP8601-003, OPL530-OC, and OPL562-OC—operate across the identical temperature range of -40°C to 85°C.

Q: Why is the SDP8601-003 obsolete?

A: The SDP8601-003 is listed as obsolete by the manufacturer. OPL530-OC and OPL562-OC are active products with ongoing manufacturing and supply availability.

Q: What does "open collector" output mean?

A: Open collector output is a logic output configuration where the output transistor can sink current to ground when active. This configuration allows direct interface with various logic families and pull-up resistor configurations in the host system.

Q: Are there any moisture sensitivity concerns with these parts?

A: All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or operation.
