Key Parameters

Substitute Part Grouping Explanation

Substitution of the SDP8611-002 is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Wavelength: 935nm (infrared detection band)
• Sensor Type: Photo Detector with Logic Output capability
• Output Type: Open Collector Inverter configuration
• Package Configuration: Side View orientation
• Operating Temperature Range: -40°C to 85°C minimum
• Regulatory Compliance: RoHS and REACH status

The OPL551-OCA from TT Electronics/Optek Technology satisfies all critical parameters. Both components operate at identical wavelength, provide equivalent logic output through open collector inverter architecture, support the same temperature operating range, and maintain equivalent regulatory compliance status. The side-view package orientation is preserved in the substitute part.

Engineering Selection Recommendations

Primary Substitute: OPL551-OCA

The OPL551-OCA is the direct functional equivalent for SDP8611-002 applications. Selection rationale is based on the following engineering factors:

1. Functional Equivalence: All critical electrical and optical parameters match exactly, including wavelength, output logic configuration, and operating temperature range.

2. Regulatory Compliance: The OPL551-OCA maintains RoHS3 compliance, which exceeds the RoHS compliance requirement of the original part. REACH status remains unaffected for both components.

3. Product Availability: The OPL551-OCA holds active product status with 970 units in current inventory, ensuring long-term sourcing availability compared to the obsolete SDP8611-002.

4. Package Compatibility: Both components utilize side-view package orientation, supporting direct mechanical integration into existing PCB layouts designed for the SDP8611-002.

5. Series Designation: The OPL551-OCA belongs to the Photologic® series from TT Electronics/Optek Technology, a recognized optical sensor product line with established reliability in industrial and consumer applications.

Frequently Asked Questions (FAQ)

Q: Can OPL551-OCA directly replace SDP8611-002 in existing designs?

A: Yes. The OPL551-OCA matches all critical parameters: 935nm wavelength, open collector inverter output, side-view package configuration, and -40°C to 85°C operating temperature range. No circuit modifications are required for functional substitution.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 represents the third iteration of RoHS regulations with expanded substance restrictions. ROHS3 compliance is a superset of RoHS compliance, meaning ROHS3-compliant components satisfy all original RoHS requirements plus additional restrictions. The OPL551-OCA exceeds the compliance requirement of the original part.

Q: Are there mechanical differences between the radial 3-lead package of SDP8611-002 and the side-view package of OPL551-OCA?

A: Both components are specified with side-view package orientation. The radial 3-lead configuration and side-view designation indicate identical mechanical orientation and lead positioning. Direct PCB layout compatibility is maintained.

Q: Why is the SDP8611-002 marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support. The OPL551-OCA, with active product status, provides continuity for new designs and legacy system maintenance.

Q: What is Moisture Sensitivity Level 1 (Unlimited)?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. Both the SDP8611-002 and OPL551-OCA can be stored and handled without special moisture control measures, simplifying inventory management and logistics.

Q: Are ECCN and HTSUS codes relevant to substitution decisions?

A: ECCN and HTSUS codes are export control and tariff classification designations used for regulatory and customs purposes. While the codes differ between manufacturers, both components fall within optical sensor classifications. Consult compliance documentation for specific export or tariff requirements applicable to your jurisdiction.
