IL410-X009 Equivalent & Substitute Parts

Part Overview

The IL410-X009 is an optoisolator with triac output manufactured by Vishay Semiconductor Opto Division. This component provides 5300Vrms isolation with zero-crossing detection, designed for applications requiring galvanic isolation in AC switching circuits. The part is classified as obsolete, making identification of active equivalent components essential for new designs and ongoing production support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IL410-X009 is based on the following critical parameters that must be maintained or exceeded:

• Output Type: Triac output configuration
• Zero Crossing Circuit: Required for synchronized AC switching
• Number of Channels: Single channel
• Voltage - Isolation: Minimum 5000Vrms (IL410-X009 specifies 5300Vrms)
• Voltage - Off State: 600 V
• Static dV/dt: 10kV/µs minimum
• Current - LED Trigger (Ift): 2mA maximum
• Current - Hold (Ih): 500µA
• Operating Temperature Range: -55°C ~ 100°C
• Mounting Type: Surface Mount
• Package / Case: 6-SMD configuration
• RoHS Compliance: ROHS3 Compliant

The substitute parts FOD410S and FOD410SD, manufactured by onsemi, meet these core substitution criteria. Both maintain the same functional architecture, isolation voltage class, zero-crossing detection, and package form factor. The primary differences are in turn-on time and forward current specifications, which remain within acceptable operational margins for triac optoisolator applications.

Parameter Comparison

Engineering Selection Recommendations

Both FOD410S and FOD410SD are active, production-supported alternatives to the obsolete IL410-X009. Selection between these two onsemi parts depends on packaging and supply chain requirements:

FOD410S is supplied in Tube packaging, suitable for lower-volume applications and manual assembly processes.

FOD410SD is supplied in Tape & Reel (TR) format, optimized for high-volume automated assembly and pick-and-place operations.

Both parts maintain ROHS3 compliance and carry CSA and UL approvals, meeting the regulatory requirements of the original component. The onsemi FOD410 series provides equivalent functional performance for triac optoisolator applications requiring galvanic isolation in the 5kV class.

Frequently Asked Questions (FAQ)

Q: Can FOD410S or FOD410SD be used as direct replacements for IL410-X009?

A: Yes. Both parts maintain the same triac output configuration, zero-crossing detection, single-channel architecture, 600V off-state voltage, 10kV/µs static dV/dt rating, and 6-SMD surface-mount package. Operating temperature range and RoHS compliance are identical.

Q: What are the differences between FOD410S and FOD410SD?

A: The primary difference is packaging format. FOD410S uses Tube packaging for manual or low-volume assembly. FOD410SD uses Tape & Reel format for automated high-volume production. Both parts are electrically and functionally identical.

Q: Why does the IL410-X009 specify 5300Vrms isolation while FOD410S and FOD410SD specify 5000Vrms?

A: Both isolation ratings fall within the same functional class for 5kV optoisolators. The 300Vrms difference represents a margin within the same product category and does not affect substitution validity for applications designed for 5kV-class isolation.

Q: Are there differences in turn-on time between IL410-X009 and the FOD410 series?

A: Yes. IL410-X009 specifies 35µs turn-on time, while FOD410S and FOD410SD specify 60µs. This difference must be evaluated against circuit timing requirements. For applications with strict timing constraints, circuit validation is necessary.

Q: Do the forward current specifications differ?

A: Yes. IL410-X009 specifies 60mA maximum DC forward current, while FOD410S and FOD410SD specify 30mA. LED drive circuits must be designed accordingly. The 2mA maximum LED trigger current (Ift) is identical across all three parts.

Q: Are all three parts RoHS compliant?

A: Yes. IL410-X009, FOD410S, and FOD410SD are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What certifications do the substitute parts carry?

A: FOD410S and FOD410SD carry CSA and UL approvals. The original IL410-X009 carries CSA and UR approvals. Both certification sets meet industrial safety requirements for optoisolator applications.
