Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SDP8601-002 is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Wavelength: 935nm
• Sensor Type: Photo Detector with Logic Output capability
• Output Configuration: Open Collector
• Package Style: Side View orientation
• Operating Temperature Range: -40°C ~ 85°C minimum
• Moisture Sensitivity Level: 1 (Unlimited)

The OPL550-OCA from TT Electronics/Optek Technology satisfies all critical parameters. Both components operate at identical wavelength, provide open collector logic output, support the same temperature range, and feature equivalent moisture sensitivity classification. The side-view package configuration is maintained across both parts.

Parameter Comparison

Engineering Selection Recommendations

The OPL550-OCA is the qualified substitute for the obsolete SDP8601-002. Selection is based on the following engineering criteria:

Functional Equivalence: Both components share identical wavelength (935nm), output type (open collector), and operating temperature specifications (-40°C ~ 85°C), ensuring direct functional replacement in circuit applications.

Compliance Status: The OPL550-OCA maintains RoHS3 compliance, exceeding the RoHS compliance level of the original part. Both components carry MSL 1 rating, indicating no moisture sensitivity restrictions during storage and handling.

Product Availability: The OPL550-OCA is currently in active production status with documented inventory availability (1387 pcs), whereas the SDP8601-002 is obsolete. This availability differential supports long-term supply chain continuity for new designs and legacy system support.

Regulatory Classification: Both parts carry identical ECCN classification (EAR99), maintaining consistent export control compliance across substitution.

Frequently Asked Questions (FAQ)

Q: Can the OPL550-OCA directly replace the SDP8601-002 in existing circuit designs?

A: Yes. Both components operate at 935nm wavelength with open collector logic output and identical temperature specifications (-40°C ~ 85°C). The side-view package configuration is maintained, supporting direct pin-compatible substitution in radial 3-lead applications.

Q: What is the significance of the obsolete status of the SDP8601-002?

A: Obsolete status indicates the manufacturer has discontinued production and support. The OPL550-OCA, being in active production, provides assured long-term availability for replacement units and new system designs requiring equivalent optical sensor functionality.

Q: Are there differences in RoHS compliance between these parts?

A: The SDP8601-002 carries RoHS compliance certification, while the OPL550-OCA carries ROHS3 compliance. ROHS3 represents an updated compliance standard and is fully backward compatible with RoHS requirements. Both parts meet environmental compliance standards for their respective manufacturing periods.

Q: How do the moisture sensitivity levels compare?

A: Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Storage, handling, and soldering processes require no special moisture control measures for either part.

Q: What packaging format is the OPL550-OCA supplied in?

A: The OPL550-OCA is supplied in bulk packaging, whereas the original SDP8601-002 packaging format is not specified in available documentation. Bulk packaging is standard for active production optical sensors and supports both individual component selection and volume procurement.

Q: Are there any differences in the series designation?

A: The OPL550-OCA belongs to the Photologic® series from TT Electronics/Optek Technology. The SDP8601-002 does not carry a designated series identifier. Series designation does not affect functional equivalence or substitution eligibility.
