Key Parameters

Substitute Part Grouping Explanation

Substitution of the SDP8407-001 is determined by the following critical parameters that must align across candidate parts:

Primary Compatibility Criteria:

• Wavelength range: 880nm to 890nm (near-infrared spectrum)
• Mounting type: Through Hole
• Orientation: Top View
• Package type: Radial
• Voltage rating: 30 V Collector Emitter Breakdown (minimum)
• Dark current: 100 nA (maximum)
• Power dissipation: 100 mW (maximum)
• Moisture sensitivity: MSL 1 (Unlimited)

Secondary Compatibility Criteria:

• Operating temperature range must encompass or exceed -40°C to 85°C
• RoHS compliance status

The substitute parts OP508FA, OP509A, and OP509B meet all primary compatibility criteria. All three candidates are manufactured by TT Electronics/Optek Technology, maintain active product status, and operate at 890nm wavelength with identical electrical ratings and package specifications to the SDP8407-001.

Parameter Comparison

Engineering Selection Recommendations

OP508FA Selection Criteria: OP508FA is suitable for applications where the 120° viewing angle approximates the original 135° specification. This part maintains all electrical parameters identical to SDP8407-001 and extends the operating temperature range to 100°C. Product status is active with ROHS3 compliance certification and REACH unaffected status, ensuring long-term availability and regulatory compliance.

OP509A and OP509B Selection Criteria: OP509A and OP509B are functionally identical parts with 50° viewing angle specifications. These parts are appropriate for applications requiring narrower field-of-view detection compared to the original 135° angle. Both maintain active product status, ROHS3 compliance, and extended operating temperature to 100°C. Selection between OP509A and OP509B depends on inventory availability and procurement lead times, as electrical and thermal specifications are equivalent.

Substitution Feasibility: All three substitute parts satisfy the mandatory electrical, thermal, and compliance requirements of the SDP8407-001. The primary differentiation factor is viewing angle, which must be evaluated against specific application optical requirements. The 10nm wavelength shift from 880nm to 890nm falls within the near-infrared spectrum and is compatible with standard photodetection circuit designs.

Frequently Asked Questions (FAQ)

Q: Can OP508FA, OP509A, or OP509B directly replace SDP8407-001 in existing designs?

A: Direct replacement is possible when the substitute part's viewing angle is compatible with the application's optical geometry. OP508FA provides the closest viewing angle match at 120° versus the original 135°. OP509A and OP509B operate at 50° viewing angle and require optical design verification for applications dependent on wide-angle detection.

Q: What is the significance of the 10nm wavelength difference between 880nm and 890nm?

A: Both wavelengths operate in the near-infrared spectrum and are compatible with standard phototransistor circuit designs. The 10nm shift represents a 1.1% change in wavelength and does not alter fundamental circuit operation or component selection criteria for typical photodetection applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts (OP508FA, OP509A, OP509B) carry ROHS3 compliance certification, exceeding the RoHS Compliant status of the original SDP8407-001. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the temperature operating range advantage of substitute parts?

A: Substitute parts extend the maximum operating temperature from 85°C to 100°C, providing 15°C additional thermal margin. Minimum operating temperature remains -40°C for all parts. This extended range enhances suitability for industrial and automotive applications.

Q: How do I select between OP509A and OP509B?

A: OP509A and OP509B are electrically and thermally equivalent. Selection should be based on inventory availability, procurement lead time, and supplier preference. Both parts carry identical specifications and compliance certifications.

Q: Is the radial through-hole package identical across all parts?

A: Yes. SDP8407-001 and all three substitute parts use identical radial through-hole package specifications, enabling direct mechanical substitution without PCB redesign or layout modifications.

Q: What compliance certifications apply to substitute parts?

A: All substitute parts carry ROHS3 compliance and REACH unaffected status. ECCN and HTSUS classifications remain consistent across all parts (EAR99 and 8541.49.7080 respectively).
