IL410-X019 Equivalent & Substitute Parts

Part Overview

The IL410-X019 is a Vishay Semiconductor Opto Division optoisolator with triac output, rated for 5300Vrms isolation voltage and designed for single-channel applications requiring zero-crossing detection. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. The part operates across the industrial temperature range of -55°C to 100°C and is housed in a 6-SMD surface mount package.

Substitute Part Grouping Explanation

Substitution eligibility for the IL410-X019 is determined by the following critical parameters:

• Output Type: Must be Triac output for functional equivalence in switching applications
• Zero Crossing Circuit: Must include zero-crossing detection capability
• Number of Channels: Must be single-channel configuration
• Voltage - Isolation: Minimum 5000Vrms (IL410-X019 specifies 5300Vrms; lower isolation ratings are not acceptable)
• Voltage - Off State: Must be 600 V or greater
• Static dV/dt (Min): Must be 10kV/µs or greater
• Mounting Type: Must be Surface Mount
• Package / Case: Must be 6-SMD configuration
• Operating Temperature Range: Must support -55°C ~ 100°C
• RoHS Status: Must be ROHS3 Compliant

The substitute parts FOD410SDV and FOD410SV, both manufactured by onsemi, meet these criteria with isolation voltage of 5000Vrms, which satisfies the minimum requirement for this application category.

Parameter Comparison

Engineering Selection Recommendations

Both FOD410SDV and FOD410SV are active-status components from onsemi that provide functional substitution for the obsolete IL410-X019. The primary differences are packaging format and minor timing/current characteristics.

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

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

Both parts maintain compliance with ROHS3 requirements and carry equivalent regulatory approvals (CSA, UL, VDE). The isolation voltage of 5000Vrms on both substitute parts meets the minimum threshold for this application category, though it is 300Vrms lower than the original IL410-X019 specification of 5300Vrms.

The turn-on time of 60µs for both onsemi alternatives is longer than the 35µs specification of the IL410-X019, and the maximum DC forward current is reduced from 60 mA to 30 mA. These differences must be evaluated against specific circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can FOD410SDV and FOD410SV be used interchangeably with IL410-X019?

A: Both onsemi parts meet the core substitution criteria for triac output optoisolators with zero-crossing detection, single-channel configuration, and 6-SMD surface mount packaging. The primary distinction is packaging format: FOD410SDV uses Tape & Reel, while FOD410SV uses Bulk. Selection depends on assembly method and procurement requirements.

Q: What is the significance of the 300Vrms difference in isolation voltage?

A: The IL410-X019 specifies 5300Vrms isolation, while both substitute parts specify 5000Vrms. This 5.7% reduction must be evaluated against the specific isolation requirements of the application circuit. If the design margin requires the full 5300Vrms specification, these substitutes may not be suitable.

Q: How do the timing differences affect circuit performance?

A: The IL410-X019 has a turn-on time of 35µs, while FOD410SDV and FOD410SV specify 60µs. This 25µs difference may impact switching speed in time-sensitive applications. Circuit simulation or testing is necessary to determine if this timing variance is acceptable for the intended application.

Q: Are there compliance or certification differences between the parts?

A: All three parts carry ROHS3 compliance and equivalent regulatory approvals (CSA, UL, VDE). Both onsemi substitutes also carry REACH Unaffected status. No compliance barriers exist for substitution.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel (FOD410SDV) is formatted for automated pick-and-place assembly equipment, while Bulk (FOD410SV) is supplied as loose components. Tape & Reel is standard for high-volume manufacturing; Bulk is typical for manual assembly, prototyping, or lower-volume production.

Q: Can I use FOD410SV if my assembly process requires Tape & Reel format?

A: No. Tape & Reel and Bulk are distinct packaging formats. FOD410SDV must be used for automated assembly processes that require tape-formatted components. Using Bulk-packaged components in automated equipment designed for tape format will cause assembly failures.
