Substitute Part Grouping Explanation
Substitution of the OPF692-2 is determined by the following critical parameters that must remain compatible:
- Wavelength: 850nm (primary functional requirement)
- Connector Type: ST (mechanical interface requirement)
- Current - DC Forward (If) (Max): 100 mA (electrical rating)
- Voltage - Forward (Vf) (Typ): Operating voltage compatibility
- RoHS and REACH Compliance: Regulatory alignment
The OPF693-2 qualifies as a manufacturer-recommended substitute. Both components share identical wavelength (850nm), connector type (ST), and maximum forward current (100 mA) specifications. The primary difference is the forward voltage: OPF692-2 operates at 2V typical, while OPF693-2 operates at 1.8V typical. This voltage differential is within acceptable substitution parameters for 850nm fiber optic transmitter applications. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity.

Engineering Selection Recommendations
The OPF693-2 is the manufacturer-recommended substitute for the obsolete OPF692-2. Selection of OPF693-2 provides the following advantages:
- Active Product Status: OPF693-2 maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete OPF692-2.
- Regulatory Compliance: Both components maintain identical ROHS3 compliance and REACH unaffected status, eliminating regulatory substitution barriers.
- Functional Equivalence: Identical wavelength (850nm), connector type (ST), and maximum forward current (100 mA) ensure optical and mechanical compatibility.
- Voltage Optimization: The reduced forward voltage (1.8V vs. 2V) of OPF693-2 represents a minor electrical parameter difference that does not compromise substitution validity for 850nm fiber optic transmitter applications.
Frequently Asked Questions (FAQ)
Q: Can OPF693-2 directly replace OPF692-2 in existing designs?
A: Yes. Both components operate at 850nm wavelength with ST connectors and 100 mA maximum forward current. The forward voltage difference (1.8V vs. 2V) is a minor parameter variation that does not prevent direct substitution in 850nm fiber optic transmitter applications.
Q: What is the significance of the forward voltage difference between OPF692-2 and OPF693-2?
A: OPF692-2 operates at 2V typical forward voltage, while OPF693-2 operates at 1.8V typical. This 0.2V difference reflects component optimization but does not affect wavelength output, connector compatibility, or current ratings that determine substitution validity.
Q: Why is OPF692-2 listed as obsolete?
A: OPF692-2 has reached end-of-life status. OPF693-2 is the active manufacturer-recommended alternative, ensuring continued access to 850nm fiber optic transmitter functionality with current production support.
Q: Are there packaging differences between OPF692-2 and OPF693-2?
A: OPF693-2 is supplied in Tray packaging. Packaging format does not affect optical or electrical substitution compatibility for this component category.
Q: Do both parts meet the same regulatory requirements?
A: Yes. Both OPF692-2 and OPF693-2 are ROHS3 compliant and REACH unaffected, maintaining identical regulatory status for component selection.
