IL420-X017 Equivalent & Substitute Parts

Part Overview

The IL420-X017 is an optoisolator with triac output manufactured by Vishay Semiconductor Opto Division. This component provides 5300Vrms isolation voltage in a single-channel configuration with 6-SMD surface mount packaging. The part is active and in production, with 943 units currently in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part's specifications, enabling direct replacement in applications where isolation voltage, output type, channel count, and package form factor are compatible.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IL420-X017 are grouped based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Output Type: Triac
• Number of Channels: 1
• Mounting Type: Surface Mount
• Package / Case: 6-SMD
• Voltage - Isolation: 5000Vrms or higher
• Voltage - Off State: 600 V
• Static dV/dt (Min): 10kV/µs or higher
• Operating Temperature Range: Must encompass or match -55°C ~ 100°C
• RoHS Status: ROHS3 Compliant

Substitute Groups:

Group 1: onsemi FOD420 Series (5000Vrms Isolation) FOD420SDV, FOD420SV, and FOD4216SDV, FOD4216SV meet the core electrical requirements with 5000Vrms isolation voltage, 10kV/µs static dV/dt, 600V off-state voltage, and 6-SMD packaging. These parts differ in packaging format (Tape & Reel, Tube, Cut Tape) and minor LED trigger current specifications but maintain functional equivalence for triac output applications.

Group 2: onsemi MOC305 Series (4170Vrms Isolation) MOC3051SR2VM, MOC3052SR2VM, and MOC3052SVM provide 4170Vrms isolation voltage, which is lower than the IL420-X017 specification. These parts are included as substitutes where isolation voltage requirements permit operation at reduced voltage ratings. Static dV/dt is specified at 1kV/µs, which is lower than the main part's 10kV/µs minimum.

Parameter Comparison

Engineering Selection Recommendations

FOD420 Series (FOD420SDV, FOD420SV, FOD4216SDV, FOD4216SV): These onsemi parts maintain the highest compatibility with IL420-X017 specifications. All four variants meet the 10kV/µs static dV/dt requirement and operate across the -55°C ~ 100°C temperature range. The primary difference is packaging format: FOD420SDV and FOD4216SDV are supplied in Tape & Reel and Cut Tape formats respectively, while FOD420SV and FOD4216SV are supplied in Tube format. FOD4216 variants feature lower LED trigger current (1.3mA maximum) compared to FOD420 variants (2mA maximum). All variants are ROHS3 compliant and hold equivalent regulatory approvals (cUL, FIMKO, UL, VDE).

MOC305 Series (MOC3051SR2VM, MOC3052SR2VM, MOC3052SVM): These onsemi parts provide functional substitution where isolation voltage requirements permit operation at 4170Vrms. The static dV/dt specification of 1kV/µs is lower than the IL420-X017 minimum of 10kV/µs. Operating temperature range is -40°C ~ 85°C, which does not extend to the full -55°C lower limit of the main part. MOC3051SR2VM and MOC3052SR2VM are supplied in Tape & Reel format, while MOC3052SVM is supplied in Tube format. All MOC305 variants are ROHS3 compliant.

Packaging Considerations: Selection between substitute parts should account for procurement and assembly requirements. Tape & Reel and Cut Tape formats support automated assembly processes, while Tube format is suitable for manual or lower-volume assembly operations.

Frequently Asked Questions (FAQ)

Q: Can FOD420 series parts directly replace IL420-X017 in all applications? A: FOD420 series parts (FOD420SDV, FOD420SV, FOD4216SDV, FOD4216SV) are direct substitutes where the 5000Vrms isolation voltage meets or exceeds application requirements. All four variants maintain the 10kV/µs static dV/dt specification and -55°C ~ 100°C operating temperature range of the main part. Packaging format differences (Tape & Reel, Cut Tape, Tube) do not affect electrical performance.

Q: What are the key differences between FOD420 and FOD4216 variants? A: FOD420 and FOD4216 variants differ in LED trigger current specification. FOD420 variants (FOD420SDV, FOD420SV) specify a maximum LED trigger current of 2mA, matching the IL420-X017. FOD4216 variants (FOD4216SDV, FOD4216SV) specify a lower maximum of 1.3mA. Both maintain identical isolation voltage, static dV/dt, and operating temperature specifications.

Q: Can MOC305 series parts substitute for IL420-X017? A: MOC305 series parts (MOC3051SR2VM, MOC3052SR2VM, MOC3052SVM) provide functional substitution where application isolation voltage requirements permit operation at 4170Vrms instead of 5300Vrms. The static dV/dt specification is 1kV/µs, lower than the IL420-X017 minimum of 10kV/µs. Operating temperature range is -40°C ~ 85°C, which does not extend to -55°C. These parts are suitable only for applications where these parameter reductions are acceptable.

Q: What packaging formats are available for substitute parts? A: FOD420 and FOD4216 series are available in three packaging formats: Tape & Reel (TR) for automated assembly, Cut Tape (CT) & Digi-Reel for semi-automated processes, and Tube for manual or low-volume assembly. MOC305 series are available in Tape & Reel and Tube formats. Selection depends on assembly process requirements and procurement volume.

Q: Are all substitute parts ROHS3 compliant? A: All substitute parts listed (FOD420SDV, FOD420SV, FOD4216SDV, FOD4216SV, MOC3051SR2VM, MOC3052SR2VM, MOC3052SVM) are ROHS3 compliant, matching the compliance status of IL420-X017.

Q: What regulatory approvals do substitute parts hold? A: FOD420 and FOD4216 series hold approvals from cUL, FIMKO, UL, and VDE. MOC305 series hold approvals from UR and VDE. IL420-X017 holds approvals from CQC, CSA, cUR, UR, and VDE. Application-specific regulatory requirements should be verified against the approval agencies listed for each part.
