Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SDP8106-001 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Wavelength range: 935nm to 940nm (near-infrared spectrum compatibility)
• Mounting type: Through Hole with Right Angle or Side View orientation
• Package type: Radial configuration
• Voltage rating: Minimum 15V Collector-Emitter breakdown voltage
• Power dissipation: 100mW or greater
• Moisture sensitivity: MSL 1 classification

Substitute Parts Identified:

Group 1 - Direct Wavelength Match (935nm):

• OP560A (TT Electronics/Optek Technology)
• OP560C (TT Electronics/Optek Technology)

Group 2 - Near-Wavelength Match (940nm):

• PT928-6B-F (Everlight Electronics Co Ltd)

All substitute parts maintain radial package configuration, through-hole mounting, and side view orientation. Wavelength deviation of 5nm (935nm to 940nm) falls within acceptable infrared sensor substitution parameters for most applications utilizing near-infrared detection.

Parameter Comparison

Engineering Selection Recommendations

OP560A and OP560C Selection:

Both OP560A and OP560C phototransistors from TT Electronics/Optek Technology are active production components with ROHS3 compliance and extended operating temperature ranges (-40°C to 100°C). These parts provide direct wavelength matching at 935nm with identical voltage ratings (15V) and power dissipation (100mW) to the SDP8106-001. The OP560 series maintains radial package configuration and side view orientation. Dark current specifications (100nA) are superior to the original part (250nA). OP560C inventory availability (3062 units) exceeds OP560A (1665 units), supporting supply chain continuity.

PT928-6B-F Selection:

The PT928-6B-F from Everlight Electronics Co Ltd operates at 940nm wavelength with enhanced electrical specifications including 30V Collector-Emitter breakdown voltage and 40mA maximum collector current. This component accommodates applications requiring higher voltage margins or increased current capacity. Operating temperature range (-25°C to 85°C) is narrower than the OP560 series. PT928-6B-F maintains through-hole right-angle mounting and radial side-view package configuration. This substitute is appropriate for designs where the 5nm wavelength shift and enhanced current handling are compatible with system requirements.

Compliance Status:

All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity classification and ROHS3 compliance, ensuring compatibility with current manufacturing and environmental standards. REACH unaffected status is confirmed for OP560A, OP560C, and PT928-6B-F.

Frequently Asked Questions (FAQ)

Q: Can OP560A or OP560C directly replace SDP8106-001 in existing designs?

A: Yes. Both OP560A and OP560C maintain identical wavelength (935nm), voltage rating (15V), power dissipation (100mW), and package configuration (radial, side view, through-hole). Mechanical and electrical compatibility is confirmed. Dark current performance is improved (100nA vs. 250nA).

Q: What is the significance of the 5nm wavelength difference between 935nm and 940nm?

A: The PT928-6B-F operates at 940nm instead of 935nm. This 5nm shift remains within the near-infrared spectrum and is acceptable for most infrared detection applications. System-level validation is required if spectral filtering or wavelength-specific detection is critical to application performance.

Q: Are there differences in viewing angle between substitute parts?

A: The SDP8106-001 specifies 50° viewing angle. OP560A and OP560C provide 56° viewing angle, offering slightly wider detection field. PT928-6B-F does not specify viewing angle. Wider viewing angle may affect application performance if narrow field-of-view is required.

Q: Which substitute part offers the best inventory availability?

A: OP560C provides the highest inventory level at 3062 units in stock, followed by OP560A at 1665 units and PT928-6B-F at 808 units.

Q: Do all substitute parts meet current environmental compliance standards?

A: Yes. All three substitute parts (OP560A, OP560C, PT928-6B-F) are ROHS3 compliant with MSL 1 rating. OP560A, OP560C, and PT928-6B-F are REACH unaffected.

Q: What is the operating temperature range difference between substitutes?

A: OP560A and OP560C support -40°C to 100°C operating range. PT928-6B-F supports -25°C to 85°C. The original SDP8106-001 does not specify operating temperature. Applications requiring extended low-temperature operation (-40°C) should use OP560 series components.

Q: Can PT928-6B-F be used in applications requiring 15V maximum voltage rating?

A: Yes. PT928-6B-F has a 30V Collector-Emitter breakdown voltage rating, which exceeds the 15V requirement. This provides additional voltage margin and is compatible with 15V-rated circuit designs.
