Substitute Part Grouping Explanation

Substitution of the OP508FC is determined by strict equivalence across the following critical parameters:

• Wavelength specification (890 nm)
• Electrical ratings (Voltage - Collector Emitter Breakdown, Collector Current, Dark Current)
• Mechanical form factor (Through Hole, Radial package, Top View orientation)
• Operating temperature range (-40°C to 100°C)
• Regulatory compliance (RoHS3, REACH Unaffected)

The OP508FA qualifies as a direct substitute based on identical electrical characteristics, mechanical configuration, and environmental specifications. The primary distinction is product status: OP508FA is active and available, whereas OP508FC is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The OP508FA is the direct equivalent substitute for the OP508FC. Both components share identical electrical specifications, mechanical configuration, and regulatory compliance certifications. The OP508FA is the recommended selection for new designs and component replacement due to its active product status and confirmed availability. The transition from OP508FC to OP508FA requires no circuit redesign or application modification, as all functional parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can OP508FA be used as a direct replacement for OP508FC in existing designs?

A: Yes. The OP508FA is electrically and mechanically identical to the OP508FC. All electrical ratings, wavelength specification, package configuration, and operating temperature range are equivalent. No circuit modifications are required.

Q: What is the primary reason for substituting OP508FC with OP508FA?

A: The OP508FC is classified as obsolete. The OP508FA is the active equivalent from the same manufacturer and product family, ensuring continued component availability and supply chain continuity.

Q: Are there any differences in packaging between OP508FC and OP508FA?

A: Both components use radial through-hole packages with top view orientation. The mechanical form factor is identical.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both OP508FC and OP508FA are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.

Q: What are the critical parameters that define substitution eligibility for this phototransistor?

A: Substitution is determined by wavelength (890 nm), electrical ratings (30 V breakdown, 5.1 mA max collector current, 100 nA max dark current), mechanical form factor (radial through-hole, top view), and operating temperature range (-40°C to 100°C).
