IL410-X019T Equivalent & Substitute Parts

Part Overview

The IL410-X019T is an optoisolator with triac output manufactured by Vishay Semiconductor Opto Division. This component provides galvanic isolation up to 5300Vrms with a single triac output channel and integrated zero-crossing detection circuit. The part is actively produced and widely used in AC power control applications requiring high-voltage isolation. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter ranges for this optoisolator category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IL410-X019T are qualified based on the following critical parameters that define functional equivalence:

• Output Type: Triac (required for AC switching applications)
• Zero Crossing Circuit: Yes (required for synchronized switching)
• Number of Channels: 1 (single-channel isolation)
• Package / Case: 6-SMD (mechanical and thermal compatibility)
• Mounting Type: Surface Mount (PCB assembly compatibility)
• Voltage - Isolation: Minimum 5000Vrms (meets or exceeds isolation requirement)
• Voltage - Off State: 600 V (standard for triac optoisolators)
• Static dV/dt (Min): 10kV/µs (noise immunity specification)
• Operating Temperature: -55°C ~ 100°C (thermal operating range)
• RoHS Status: ROHS3 Compliant (environmental compliance)

The substitute parts FOD410SDV and FOD410SV from onsemi meet all critical substitution criteria. Both maintain triac output configuration, zero-crossing detection, single-channel isolation, and 6-SMD surface-mount packaging. Isolation voltage is specified at 5000Vrms, which satisfies the minimum isolation requirement. All other electrical parameters remain within acceptable ranges for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both FOD410SDV and FOD410SV are qualified substitutes for the IL410-X019T based on functional equivalence and compliance certifications. Selection between these options depends on packaging requirements:

FOD410SDV is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes and high-volume production environments.

FOD410SV is supplied in Bulk packaging, suitable for manual assembly, prototyping, or lower-volume applications.

All three parts maintain ROHS3 compliance and carry relevant safety certifications (CSA, VDE). The onsemi substitutes carry UL certification in place of UR certification on the Vishay part. Both substitute parts are actively produced and maintain equivalent inventory availability.

Frequently Asked Questions (FAQ)

Q: Can FOD410SDV and FOD410SV be used interchangeably with IL410-X019T?

A: Yes, both onsemi parts are functionally equivalent substitutes. The primary difference is packaging format: FOD410SDV comes in Tape & Reel, while FOD410SV comes in Bulk. Both maintain identical electrical specifications and 6-SMD surface-mount package configuration.

Q: What is the difference between FOD410SDV and FOD410SV?

A: The parts are electrically identical. FOD410SDV is supplied in Tape & Reel (TR) packaging for automated pick-and-place assembly. FOD410SV is supplied in Bulk packaging. Select based on your assembly process requirements.

Q: Are there differences in isolation voltage between the main part and substitutes?

A: The IL410-X019T specifies 5300Vrms isolation, while FOD410SDV and FOD410SV specify 5000Vrms. Both meet the minimum isolation requirement for typical AC power control applications. Verify isolation voltage requirements for your specific application.

Q: Do the substitute parts have the same turn-on time?

A: No. The IL410-X019T has a turn-on time of 35µs, while FOD410SDV and FOD410SV have 60µs turn-on time. This difference may affect switching speed in time-critical applications. Confirm timing requirements for your circuit design.

Q: Are all three parts RoHS compliant?

A: Yes, all three parts are ROHS3 compliant and suitable for applications requiring environmental compliance.

Q: What certifications do the substitute parts carry?

A: FOD410SDV and FOD410SV carry CSA, UL, and VDE certifications. The original IL410-X019T carries CSA, UR, and VDE certifications. Both certification sets are recognized for industrial and consumer applications.
