Engineering Selection Recommendations

OP216A as Substitute for SE1470-004L:

The OP216A from TT Electronics/Optek Technology presents a functional alternative to the obsolete SE1470-004L based on the following factors:

Electrical Compatibility: Both components share identical typical forward voltage (1.8V), enabling direct integration into existing power supply circuits without modification.

Optical Characteristics: The OP216A operates at 890nm wavelength compared to the SE1470-004L at 880nm. Applications utilizing these components in wavelength-specific detection systems must evaluate whether the 10nm difference affects system performance. The OP216A delivers 1.2mW/cm² at 50mA, compared to the SE1470-004L at 1.65mW/cm² at 20mA. Circuit design must account for this optical output difference.

Current Rating: The OP216A is rated for 100mA maximum forward current, exceeding the SE1470-004L specification of 50mA. Existing circuits designed for 50mA operation remain compatible when current-limiting resistors maintain the original operating point.

Viewing Angle: Both components feature identical 24° viewing angles, ensuring compatible spatial emission characteristics.

Mechanical Considerations: The OP216A uses a radial package configuration, while the SE1470-004L uses a coaxial metal can package. PCB layout and mechanical assembly modifications are required to accommodate the different package geometry.

Product Status and Availability: The OP216A is actively manufactured and maintained by TT Electronics/Optek Technology, ensuring long-term availability and supply chain stability compared to the obsolete SE1470-004L.

Compliance: Both components meet applicable RoHS requirements. The OP216A carries ROHS3 compliance certification.

Frequently Asked Questions (FAQ)

Q: Can the OP216A directly replace the SE1470-004L without circuit modification?

A: Electrical substitution is possible due to identical forward voltage (1.8V). However, the different package type (radial vs. coaxial metal can) requires mechanical redesign of the PCB layout and mechanical assembly. Additionally, the higher maximum current rating of the OP216A (100mA vs. 50mA) requires that existing current-limiting circuits maintain the original operating current.

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

A: The 10nm difference between the SE1470-004L (880nm) and OP216A (890nm) may be significant in applications where infrared emission is matched to specific detector sensitivities or absorption characteristics. Applications utilizing narrowband detection filters or wavelength-dependent optical systems require evaluation to confirm compatibility. General-purpose infrared applications typically tolerate this wavelength variation.

Q: How does the radiant intensity difference affect system performance?

A: The SE1470-004L delivers 1.65mW/cm² at 20mA, while the OP216A delivers 1.2mW/cm² at 50mA. The SE1470-004L provides higher intensity at lower current. Applications requiring specific optical output levels must evaluate whether the OP216A intensity meets system requirements. Circuit design may require adjustment of operating current or optical path geometry to compensate for intensity differences.

Q: Are both components RoHS compliant?

A: Yes. The SE1470-004L is RoHS Compliant. The OP216A is ROHS3 Compliant. Both meet applicable regulatory requirements for hazardous substance restrictions.

Q: What are the package implications for PCB design?

A: The SE1470-004L uses a coaxial metal can package with through-hole mounting. The OP216A uses a radial package with through-hole mounting. These different package geometries require modification of PCB footprints, hole spacing, and mechanical clearances. Existing PCB designs for the SE1470-004L cannot accommodate the OP216A without layout revision.

Q: Is the OP216A suitable for the full operating temperature range of the SE1470-004L?

A: The SE1470-004L operates from -55°C to 125°C. The OP216A operates from -65°C to 125°C. The OP216A supports a lower minimum temperature, making it suitable for applications requiring the full SE1470-004L temperature range and applications requiring operation below -55°C.
