IL255-X007T Equivalent & Substitute Parts

Part Overview

The IL255-X007T is an optoisolator transistor with base output manufactured by Vishay Semiconductor Opto Division. This component provides 5300Vrms isolation with a single channel configuration in a 6-SMD surface mount package. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity. Equivalent parts must maintain the same isolation voltage, output configuration, and package footprint to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IL255-X007T is determined by the following critical parameters:

• Isolation Voltage: Must equal 5300Vrms to maintain electrical safety and regulatory compliance
• Output Configuration: Must be Transistor with Base to preserve circuit interface compatibility
• Package Type: Must be 6-SMD, Gull Wing to ensure PCB footprint compatibility
• Number of Channels: Must be 1 channel
• Operating Temperature Range: Must support -55°C ~ 100°C minimum
• Regulatory Compliance: Must maintain ROHS3 compliance

The H11A2XSM from Isocom Components 2004 LTD meets all critical substitution criteria and is classified as an active product with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The H11A2XSM is a direct functional equivalent to the IL255-X007T. Both components share identical electrical specifications for isolation voltage, output configuration, current transfer ratio, and operating temperature range. The H11A2XSM maintains ROHS3 compliance and is currently in active production status, ensuring long-term availability and supply chain continuity.

Selection of the H11A2XSM eliminates obsolescence risk associated with the IL255-X007T while preserving all critical electrical and mechanical characteristics required for circuit operation. The substitute component is suitable for new designs and production replacement scenarios where the original part is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the H11A2XSM replace the IL255-X007T in existing designs?

A: Yes. The H11A2XSM is a direct substitute. Both components have identical isolation voltage (5300Vrms), output type (Transistor with Base), package configuration (6-SMD, Gull Wing), and electrical specifications. No circuit modifications are required.

Q: What is the primary reason for substitution?

A: The IL255-X007T is classified as obsolete. The H11A2XSM is an active product with current manufacturing support, ensuring availability for production and design continuity.

Q: Are there any differences in input type between these components?

A: The IL255-X007T accepts both AC and DC input signals. The H11A2XSM accepts DC input only. Circuit designs must verify that DC input operation is compatible with the application requirements.

Q: Do both components have the same package footprint?

A: Yes. Both use 6-SMD, Gull Wing surface mount packages. PCB layouts designed for the IL255-X007T require no modification for the H11A2XSM.

Q: Are regulatory certifications equivalent?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting the same regulatory requirements.

Q: What is the difference in current output specifications?

A: The IL255-X007T does not specify maximum output current per channel. The H11A2XSM specifies 50mA maximum output current per channel. This additional specification in the substitute part provides design guidance for output load calculations.
