IL2-X009 Equivalent & Substitute Parts

Part Overview

The IL2-X009 is an optoisolator transistor with base output manufactured by Vishay Semiconductor Opto Division. This 6-SMD surface mount component provides 5300Vrms isolation with single-channel transistor output and integrated base connection. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production support. Suitable alternatives maintain the same electrical isolation, output configuration, and mechanical form factor while offering active product status and extended availability.

Substitute Part Grouping Explanation

Substitution for the IL2-X009 is determined by the following critical parameters:

Mandatory Matching Criteria:

Voltage - Isolation: 5300Vrms (electrical isolation requirement)
Output Type: Transistor with Base (functional configuration)
Package / Case: 6-SMD, Gull Wing (mechanical compatibility)
Mounting Type: Surface Mount (assembly compatibility)
Number of Channels: 1 (circuit integration requirement)

Allowable Variation Ranges:

Current Transfer Ratio (Min): 100% or higher acceptable
Voltage - Output (Max): 70V or higher acceptable
Current - Output / Channel: 50mA or higher acceptable
Vce Saturation (Max): 250mV or higher acceptable (lower saturation voltage preferred)
Operating Temperature: Must encompass or exceed -40°C ~ 100°C range

Substitute parts meeting these criteria are functionally compatible for direct replacement in applications designed for the IL2-X009. The H11AV series from Isocom Components 2004 LTD provides active alternatives with 5300Vrms isolation and identical mechanical packaging.

Engineering Selection Recommendations

Primary Substitutes (5300Vrms Isolation):

H11AV1XSM / H11AV1XSMT&R are the closest functional equivalents. Both maintain 5300Vrms isolation with 100% minimum current transfer ratio, matching the IL2-X009 performance envelope. These parts carry active product status and ROHS3 compliance. The H11AV1XSMT&R variant in Tape & Reel packaging offers higher inventory availability (2117 pcs) for production volumes.

H11AV2XSM / H11AV2XSMT&R provide 5300Vrms isolation with reduced minimum current transfer ratio (50%). These are suitable for applications where lower gain is acceptable. H11AV2XSMT&R inventory is 2145 pcs.

H11AV3XSM / H11AV3XSMT&R provide 5300Vrms isolation with minimum current transfer ratio of 20%. These are suitable only for applications with minimal gain requirements. H11AV3XSMT&R inventory is 2089 pcs.

Secondary Substitutes (7.5Vpk Isolation):

IL2SM / IL2SMT&R maintain the original IL2 series designation with 7.5Vpk isolation and 100% minimum current transfer ratio matching the IL2-X009. These are suitable only for applications where lower isolation voltage is acceptable. IL2SMT&R inventory is 1001 pcs.

Packaging Considerations:

Tube packaging (XSM variants) is suitable for manual assembly and small-volume applications. Tape & Reel (T&R variants) is required for automated pick-and-place assembly and production environments.

Frequently Asked Questions (FAQ)

Q: Can H11AV series parts directly replace IL2-X009 in existing designs?

A: H11AV1XSM and H11AV1XSMT&R provide direct functional replacement with identical 5300Vrms isolation, 100% minimum current transfer ratio, 70V maximum output voltage, and 50mA output current. All mechanical and electrical parameters align with IL2-X009 requirements. Vce saturation is higher (400mV vs 250mV), which is acceptable in most applications but should be verified for designs with tight saturation specifications.

Q: What is the difference between H11AV1, H11AV2, and H11AV3 variants?

A: The variants differ in minimum current transfer ratio: H11AV1 (100%), H11AV2 (50%), and H11AV3 (20%). All maintain 5300Vrms isolation and identical output specifications. Selection depends on the required gain characteristics of the application. H11AV1 is the closest match to IL2-X009 performance.

Q: Should I use Tube or Tape & Reel packaging?

A: Tube packaging is appropriate for manual assembly, prototyping, and low-volume production. Tape & Reel packaging is required for automated surface mount assembly lines. Both packaging options are electrically and functionally identical.

Q: Are IL2SM and IL2SMT&R suitable replacements?

A: IL2SM and IL2SMT&R are suitable only if the application can tolerate 7.5Vpk isolation instead of 5300Vrms. These parts maintain the original IL2 series characteristics with 100% minimum current transfer ratio and identical output specifications. They are not recommended for applications requiring 5300Vrms isolation.

Q: What compliance certifications apply to substitute parts?

A: All substitute parts listed are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited). H11AV series parts include REACH Unaffected status. All parts are classified under ECCN EAR99 and HTSUS 8541.49.8000.

Q: How does operating temperature range affect substitution?

A: IL2-X009 operates from -40°C to 100°C. H11AV series parts operate from -55°C to 100°C, providing extended low-temperature capability. IL2SM and IL2SMT&R operate from -25°C to 100°C. For applications requiring -40°C operation, H11AV series is preferred. For applications requiring -25°C or higher, IL2SM variants are acceptable.
