Key Parameters

Substitute Part Grouping Explanation

Substitution of the SE2470-001 is determined by the following critical parameters:

Wavelength Compatibility: The SE2470-001 operates at 880nm. Substitute parts must operate within the near-infrared spectrum at 890nm, which represents a 10nm offset within acceptable tolerance for most infrared sensing applications.

Current Rating: The SE2470-001 supports a maximum forward current of 75mA. Substitute parts with higher current ratings (100mA) are electrically compatible when operated within the original design current envelope.

Forward Voltage: The SE2470-001 has a typical forward voltage of 1.8V. Substitute parts with forward voltages of 1.3V to 2.0V are compatible with standard circuit designs accommodating this voltage range.

Viewing Angle: The SE2470-001 features an 18° viewing angle. Substitute parts with 24° viewing angles provide broader light distribution and remain functionally compatible.

Package and Mounting: The SE2470-001 uses Surface Mount Mini-pill packaging. Substitute parts maintaining Mini-pill surface mount configuration preserve PCB layout compatibility. The OP233 substitute uses Through Hole TO-46-2 packaging and requires circuit board redesign.

Operating Temperature Range: The SE2470-001 operates from -55°C to 125°C. Substitute parts with -65°C to 125°C ranges provide extended low-temperature performance.

Compliance and Status: All substitute parts are RoHS3 compliant and carry Active product status, ensuring long-term availability and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

OP224 (TT Electronics/Optek Technology): This part is the primary substitute for SE2470-001. It maintains identical forward voltage (1.8V), Mini-pill surface mount packaging, and 18° viewing angle. The OP224 is rated for 100mA maximum current and operates across -65°C to 125°C, providing extended low-temperature capability. Product status is Active with ROHS3 compliance, ensuring long-term supply availability and regulatory compliance. Inventory availability is 5867 units.

OP223 (TT Electronics/Optek Technology): This part is a secondary substitute suitable for applications where lower forward voltage (1.3V) is advantageous for power efficiency. It maintains Mini-pill surface mount packaging and operates across -65°C to 125°C. The 24° viewing angle provides broader light distribution compared to the original 18° specification. Product status is Active with ROHS3 compliance. Inventory availability is 1028 units.

OP233 (TT Electronics/Optek Technology): This part is a tertiary substitute applicable only when circuit board redesign is feasible. It uses Through Hole TO-46-2 packaging, requiring PCB layout modification. The OP233 maintains the 18° viewing angle and operates across -65°C to 125°C with 2.0V typical forward voltage. Product status is Active with ROHS3 compliance. Inventory availability is 30149 units, the highest among all substitutes.

All substitute parts carry Active product status and ROHS3 compliance, ensuring regulatory alignment and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can OP224 be used as a direct replacement for SE2470-001 without circuit modification?

A: Yes. The OP224 maintains identical forward voltage (1.8V), Mini-pill surface mount packaging, and 18° viewing angle as the SE2470-001. No circuit modification is required. The higher maximum current rating (100mA vs. 75mA) does not prevent substitution when the original design operates within the 75mA envelope.

Q: What is the wavelength difference between SE2470-001 (880nm) and the substitute parts (890nm)?

A: The substitute parts operate at 890nm, representing a 10nm offset from the original 880nm specification. This wavelength difference falls within the near-infrared spectrum and is compatible with standard infrared sensing applications designed for the 880nm range.

Q: Why does OP233 require circuit board redesign?

A: The OP233 uses Through Hole TO-46-2 packaging, whereas the SE2470-001 uses Surface Mount Mini-pill packaging. These package types have different footprints and mounting requirements, necessitating PCB layout modification. OP223 and OP224 maintain Mini-pill surface mount packaging and do not require board redesign.

Q: Which substitute part has the best low-temperature performance?

A: All substitute parts (OP223, OP224, OP233) operate from -65°C to 125°C, compared to the SE2470-001 range of -55°C to 125°C. All three substitutes provide 10°C extended low-temperature capability.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts carry ROHS3 compliance certification. The original SE2470-001 is RoHS Compliant. All parts meet current regulatory requirements for hazardous substance restrictions.

Q: What is the difference in viewing angle between SE2470-001 and the substitute parts?

A: The SE2470-001 and OP233 both feature 18° viewing angles. The OP223 and OP224 feature 24° viewing angles, providing broader light distribution. Selection depends on application-specific beam width requirements.

Q: Which substitute part has the highest inventory availability?

A: The OP233 has the highest inventory availability at 30149 units. The OP224 has 5867 units, and the OP223 has 1028 units. The original SE2470-001 has 1026 units remaining in stock.
