Substitute Part Grouping Explanation

The OPF794 qualifies as a direct substitute for the OPF792 based on matching electrical and mechanical parameters. Substitution eligibility is determined by the following criteria:

• Identical wavelength specification: 800nm
• Matching spectral range: 800nm ~ 1000nm
• Same diode type: PIN
• Identical responsivity: 0.55 A/W @ 850nm
• Matching response time: 2ns
• Identical maximum reverse voltage: 50 V
• Matching dark current: 500pA
• Identical operating temperature range: -40°C ~ 85°C
• Same mounting type: Through Hole
• Equivalent compliance certifications: ROHS3 Compliant, REACH Unaffected

The OPF794 maintains active product status, providing supply continuity for applications currently using the obsolete OPF792.

Parameter Comparison

Engineering Selection Recommendations

The OPF794 is the recommended substitute for the obsolete OPF792. Both components are manufactured by TT Electronics/Optek Technology and maintain identical electrical specifications and compliance certifications. The OPF794 provides active product status with current manufacturing support and inventory availability (810 Pcs in stock), ensuring supply chain continuity for 800nm photodiode applications requiring PIN diode configuration, 2ns response time, and 50V reverse voltage rating.

Both parts comply with ROHS3 and REACH requirements, making them suitable for applications subject to environmental and regulatory compliance standards. The through-hole mounting type remains consistent between both parts, allowing direct circuit board integration without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the OPF794 be used as a direct replacement for the OPF792?

A: Yes. The OPF794 is a direct substitute with identical electrical parameters, including wavelength (800nm), spectral range (800nm ~ 1000nm), responsivity (0.55 A/W @ 850nm), response time (2ns), maximum reverse voltage (50V), dark current (500pA), and operating temperature range (-40°C ~ 85°C). Both use PIN diode configuration and through-hole mounting.

Q: What is the primary reason to transition from OPF792 to OPF794?

A: The OPF792 is classified as obsolete, while the OPF794 maintains active product status. Transitioning to the OPF794 ensures long-term supply availability and manufacturing support for new designs and production continuity.

Q: Are there any compliance differences between OPF792 and OPF794?

A: No. Both components are ROHS3 compliant and REACH unaffected, with identical moisture sensitivity level (MSL 1 - Unlimited). Compliance certifications are equivalent.

Q: Do the OPF792 and OPF794 require different circuit board layouts?

A: No. Both components use through-hole mounting type, allowing identical circuit board integration without layout modifications or redesign.

Q: What are the key electrical parameters that define substitution eligibility for this photodiode?

A: Substitution is determined by matching wavelength (800nm), spectral range (800nm ~ 1000nm), diode type (PIN), responsivity (0.55 A/W @ 850nm), response time (2ns), maximum reverse voltage (50V), dark current (500pA), and operating temperature range (-40°C ~ 85°C).
