Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the SDP8276-001 is determined by the following critical parameters:

Mounting Type: Through-hole configuration is required for mechanical and electrical compatibility with existing PCB layouts.

Optical Sensor Category: Both components must function as photodiode optical sensors to maintain application functionality.

Reverse Voltage Rating: The substitute must support the maximum reverse voltage specification of the original part or higher to ensure safe operation within circuit design constraints.

Dark Current: The substitute's dark current specification must not exceed the original specification to maintain signal-to-noise performance characteristics.

Operating Temperature Range: The substitute must cover the minimum operating temperature range of -40°C to 85°C required by the application.

Response Time: The substitute's response time must be equal to or faster than the original 50-nanosecond specification to maintain or improve system timing performance.

RoHS and Regulatory Compliance: The substitute must maintain equivalent or superior compliance status to ensure regulatory and environmental requirements are met.

The OP950 manufactured by TT Electronics/Optek Technology meets these substitution criteria across all critical parameters.

Engineering Selection Recommendations

Primary Substitute: OP950

The OP950 photodiode optical sensor is the direct functional equivalent for SDP8276-001 applications. Selection of OP950 is supported by the following engineering factors:

Product Availability: OP950 maintains active manufacturing status with 7252 units in current inventory, ensuring long-term supply chain continuity compared to the obsolete SDP8276-001.

Performance Superiority: OP950 demonstrates improved performance across all measurable parameters: response time of 5 nanoseconds (10× faster than the 50-nanosecond original), reverse voltage rating of 60 volts (20% higher margin), and dark current of 1 nanoampere (50× lower noise floor).

Temperature Range Extension: OP950 operating temperature range extends to 100°C, providing additional thermal margin beyond the original -40°C to 85°C specification.

Regulatory Compliance: OP950 maintains ROHS3 compliance status, meeting current and future environmental regulations. Both components carry identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), eliminating moisture handling requirement changes.

Mechanical Compatibility: Through-hole mounting configuration is identical, allowing direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can OP950 be used as a direct replacement for SDP8276-001 in existing designs?

A: Yes. OP950 is mechanically and electrically compatible with SDP8276-001. Both components use through-hole mounting and operate within overlapping electrical specifications. OP950 performance parameters exceed or match all SDP8276-001 requirements.

Q: What are the key differences between SDP8276-001 and OP950?

A: The primary differences are response time (OP950: 5ns versus SDP8276-001: 50ns), dark current (OP950: 1nA versus SDP8276-001: 50nA), reverse voltage rating (OP950: 60V versus SDP8276-001: 50V), and operating temperature maximum (OP950: 100°C versus SDP8276-001: 85°C). OP950 also maintains active product status while SDP8276-001 is obsolete.

Q: Are there packaging differences between these components?

A: Both components use through-hole mounting. SDP8276-001 packaging information is not specified in available documentation. OP950 is supplied in bulk packaging. Verify physical dimensions and pin configuration compatibility with your specific PCB layout requirements.

Q: Does OP950 require different circuit design considerations?

A: No design changes are required. OP950 operates within the same voltage and temperature ranges as SDP8276-001. The superior performance characteristics (faster response time, lower dark current, higher voltage rating) provide additional design margin without requiring circuit modifications.

Q: What is the wavelength specification for these components?

A: SDP8276-001 wavelength specification is not provided in available documentation. OP950 operates at 935 nanometers with a spectral range of 500nm to 1100nm, making it suitable for near-infrared applications.

Q: Are moisture handling procedures different for OP950?

A: No. Both components carry identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), indicating no moisture sensitivity. Standard handling procedures apply to both components.
