FOD617C300 Equivalent & Substitute Parts

Part Overview

The FOD617C300 is an optoisolator with transistor output manufactured by onsemi, featuring 5000Vrms isolation voltage in a 4-DIP package. This component provides galvanic isolation for low-speed switching applications with a single channel configuration. The FOD617C300 is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. Suitable alternatives must maintain the same isolation voltage, output type, package configuration, and electrical performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FOD617C300 are qualified based on the following critical parameters:

• Voltage - Isolation: 5000Vrms (mandatory match)
• Output Type: Transistor (mandatory match)
• Package / Case: 4-DIP (0.300", 7.62mm) (mandatory match)
• Number of Channels: 1 (mandatory match)
• Current Transfer Ratio range: 100% to 200% @ 10mA or equivalent specification
• Voltage - Output (Max): 70V (mandatory match)
• Current - Output / Channel: 50mA (mandatory match)
• Operating Temperature: -55°C ~ 110°C (mandatory match)

Three substitute parts meet these criteria: FOD817C300, FOD617C, and VO615A-3X001. Each maintains full electrical and mechanical compatibility with the original FOD617C300 specification.

Parameter Comparison

Engineering Selection Recommendations

FOD817C300 (onsemi, Active): This part is the primary recommended substitute. It maintains identical isolation voltage, output type, package, and current ratings. The FOD817C300 offers improved current transfer ratio performance (200% to 400% @ 5mA) and lower Vce saturation (200mV vs. 400mV), providing superior switching characteristics. Active product status ensures long-term availability and supply continuity. ROHS3 compliance supports modern manufacturing requirements.

FOD617C (onsemi, Last Time Buy): This part provides parametric equivalence with identical electrical specifications to the FOD617C300. It maintains the same current transfer ratio range and Vce saturation characteristics. Last Time Buy status indicates limited remaining availability; this option is suitable only for applications requiring exact parameter matching and where supply constraints are acceptable. ROHS3 compliance is available.

VO615A-3X001 (Vishay Semiconductor Opto Division, Active): This cross-manufacturer substitute maintains all critical electrical parameters and package compatibility. The VO615A-3X001 offers active product status with established supply availability. Minor variations exist in forward voltage (1.43V vs. 1.35V) and Vce saturation (300mV vs. 400mV), both within acceptable operating margins. ROHS3 compliance is provided. This option is suitable for applications where multi-source qualification is required.

Frequently Asked Questions (FAQ)

Q: Can FOD817C300 be used as a direct replacement for FOD617C300?

A: Yes. The FOD817C300 maintains identical isolation voltage (5000Vrms), output type (transistor), package configuration (4-DIP), and current ratings (50mA). The improved current transfer ratio and lower saturation voltage represent performance enhancements compatible with FOD617C300 circuit designs.

Q: What is the difference between FOD617C and FOD617C300?

A: The FOD617C and FOD617C300 share identical electrical specifications and package configuration. The primary difference is product status: FOD617C300 is obsolete while FOD617C is Last Time Buy. Both provide parametric equivalence for direct substitution.

Q: Is VO615A-3X001 compatible with FOD617C300 in existing designs?

A: Yes. The VO615A-3X001 maintains the same isolation voltage, output type, package, and current ratings. Minor parameter variations (forward voltage and saturation voltage) fall within normal operating tolerances and do not affect circuit functionality in standard switching applications.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: isolation voltage (5000Vrms), output type (transistor), package type (4-DIP), number of channels (1), maximum output voltage (70V), maximum output current (50mA), and operating temperature range (-55°C to 110°C). All qualified substitutes maintain these parameters.

Q: Which substitute offers the best long-term availability?

A: FOD817C300 and VO615A-3X001 both carry Active product status, ensuring established supply chains and long-term availability. FOD617C is Last Time Buy, indicating limited remaining stock and eventual discontinuation.

Q: Are all substitutes RoHS compliant?

A: FOD817C300, FOD617C, and VO615A-3X001 are all ROHS3 compliant, meeting modern environmental and manufacturing standards.
