IL4116-X009 Equivalent & Substitute Parts

Part Overview

The IL4116-X009 is a 5.3kV isolation optoisolator with triac output manufactured by Vishay Semiconductor Opto Division. This component provides galvanic isolation for AC switching applications with zero-crossing detection capability. The part is classified as obsolete, making identification of equivalent substitute components essential for ongoing design support and procurement continuity. Active alternatives maintain functional compatibility while offering improved availability and current product status.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the IL4116-X009 are qualified based on the following critical parameters that determine functional equivalence:

Isolation Voltage: The IL4116-X009 specifies 5300Vrms isolation. Substitute parts must maintain isolation voltage at or above 5000Vrms to ensure adequate safety margins in high-voltage isolation applications.

Output Configuration: All substitutes must feature triac output with zero-crossing detection to maintain compatibility with AC switching circuits designed for the original component.

Package Compatibility: The 6-SMD surface mount package is mandatory for mechanical and electrical compatibility with existing PCB layouts.

Electrical Characteristics: Key parameters including off-state voltage (600V), static dV/dt rating (10kV/µs), operating temperature range (-55°C to 100°C), and channel count (1) must be maintained or exceeded.

Regulatory Compliance: RoHS3 compliance and MSL rating of 1 are required for manufacturing and environmental standards alignment.

The FOD410S and FOD410SD from onsemi meet these substitution criteria while offering active product status and improved procurement availability.

Engineering Selection Recommendations

FOD410S and FOD410SD Selection Basis:

Both FOD410S and FOD410SD are active products from onsemi that provide functional substitution for the obsolete IL4116-X009. The selection between these two variants depends on procurement and assembly requirements rather than electrical performance, as both share identical electrical specifications.

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

FOD410SD is supplied in tape and reel format and is optimized for high-volume automated assembly operations.

Both substitutes maintain the required 6-SMD surface mount package configuration, zero-crossing detection capability, and triac output topology. The isolation voltage of 5000Vrms in the FOD410 series is within acceptable substitution parameters for applications designed around the IL4116-X009's 5300Vrms rating.

Regulatory compliance is maintained across all three components with ROHS3 certification and MSL 1 rating. The FOD410 series carries CSA and UL approvals, providing equivalent safety certifications for industrial and consumer applications.

Frequently Asked Questions (FAQ)

Q: Can FOD410S or FOD410SD directly replace IL4116-X009 in existing designs?

A: Yes. Both FOD410 variants maintain the same 6-SMD surface mount package, triac output configuration, zero-crossing detection, and operating temperature range. The electrical parameters are compatible with applications designed for the IL4116-X009.

Q: What is the difference between FOD410S and FOD410SD?

A: The electrical specifications are identical. FOD410S is packaged in tubes for manual or low-volume assembly, while FOD410SD is supplied in tape and reel format for automated high-volume production. Select based on your assembly process requirements.

Q: Is the lower isolation voltage of FOD410 (5000Vrms vs. 5300Vrms) a concern?

A: The 300Vrms difference represents a 5.7% reduction in isolation rating. For applications with design margins that accommodate the original 5300Vrms specification, the 5000Vrms FOD410 rating remains within acceptable substitution parameters. Circuit-level isolation requirements should be evaluated for your specific application.

Q: Are there any timing differences between IL4116-X009 and FOD410?

A: The FOD410 series has a longer turn-on time (60µs vs. 35µs) and higher hold current (500µA vs. 200µA). These differences may affect circuit timing in applications with tight switching requirements. Verify timing compatibility with your circuit design.

Q: Do FOD410S and FOD410SD have the same regulatory approvals as IL4116-X009?

A: Both FOD410 variants carry CSA and UL certifications. The IL4116-X009 includes additional approvals (BSI, cUR, FIMKO, UR). For applications requiring specific regulatory certifications, confirm that CSA and UL meet your compliance requirements.

Q: What is the current availability status?

A: IL4116-X009 is obsolete with limited stock. FOD410S and FOD410SD are active products with robust inventory availability (1259 and 3400 units respectively), ensuring long-term procurement continuity.
