TIL111SR2VM Equivalent & Substitute Parts

Part Overview

The TIL111SR2VM is a 7500Vpk optoisolator transistor with base output manufactured by onsemi in 6-SMD surface mount packaging. This component provides galvanic isolation for single-channel DC input applications with transistor output capability. The part is currently classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement planning. Substitute parts maintain the core isolation voltage, output type, and electrical performance characteristics while offering alternative packaging or active product status options.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TIL111SR2VM is determined by the following critical parameters:

Core Electrical Requirements (Non-Negotiable):

• Voltage - Isolation: 7500Vpk minimum
• Output Type: Transistor with Base
• Number of Channels: 1
• Voltage - Output (Max): 30V or greater
• Vce Saturation (Max): 400mV or lower
• Operating Temperature Range: Must encompass -40°C to 100°C

Packaging Flexibility:

• Surface Mount (6-SMD, Gull Wing) preferred for direct replacement
• Through Hole (6-DIP) acceptable as functional equivalent with board layout modification
• Tape & Reel packaging acceptable for high-volume applications

Acceptable Variations:

• Current - Output / Channel: 2mA or greater
• Rise / Fall Time: 10µs or faster acceptable
• Input Type: DC (fixed requirement)
• Voltage - Forward (Vf): 1.2V nominal acceptable

Substitute parts are grouped into two categories: Direct Replacements (identical packaging) and Functional Equivalents (different packaging, identical electrical performance).

Parameter Comparison

Engineering Selection Recommendations

TIL111M (Direct Functional Equivalent): Select TIL111M for applications requiring active product status and RoHS3 compliance. This part maintains identical electrical specifications and isolation voltage. The through-hole 6-DIP package requires PCB layout modification but provides equivalent performance. Active product status ensures long-term availability and supply chain stability.

TIL111SM (Packaging-Matched Equivalent): Select TIL111SM for direct PCB footprint compatibility with the TIL111SR2VM. Both parts use 6-SMD, Gull Wing surface mount packaging. However, TIL111SM shares obsolete product status with the main part, limiting long-term procurement viability.

TIL111SMT&R (Enhanced Performance Alternative): The TIL111SMT&R from Isocom Components 2004 LTD offers active product status, RoHS3 compliance, and improved switching performance (2µs rise/fall time versus 10µs). However, this part specifies 7.5Vpk isolation voltage, which does not meet the 7500Vpk isolation requirement of the main part. This part is not suitable for direct substitution.

For new designs or long-term production, TIL111M is the recommended substitute, providing active status and compliance certifications despite packaging differences.

Frequently Asked Questions (FAQ)

Q: Can TIL111M replace TIL111SR2VM directly on the PCB?

A: TIL111M provides electrical equivalence but requires PCB layout modification. TIL111M uses 6-DIP through-hole packaging while TIL111SR2VM uses 6-SMD surface mount. Footprints are not compatible without redesign. For direct footprint replacement, TIL111SM maintains the 6-SMD, Gull Wing package.

Q: What is the critical difference between TIL111SMT&R and the main part?

A: TIL111SMT&R specifies 7.5Vpk isolation voltage, not 7500Vpk. This represents a 1000-fold reduction in isolation capability and disqualifies it as a substitute for applications requiring 7500Vpk isolation.

Q: Why is TIL111M recommended despite packaging differences?

A: TIL111M maintains all critical electrical parameters (7500Vpk isolation, 30V output, 400mV Vce saturation, 1 channel, transistor with base output) and holds active product status with RoHS3 compliance. These factors ensure long-term availability and regulatory compliance, outweighing packaging considerations in most applications.

Q: Are there inventory implications for substitute selection?

A: TIL111M has 8359 units in stock, TIL111SM has 12100 units, and TIL111SMT&R has 775 units. Inventory levels should be evaluated against project timelines and volume requirements.

Q: What compliance certifications apply to each substitute?

A: TIL111M and TIL111SMT&R are ROHS3 compliant. All parts (main and substitutes) are REACH Unaffected and classified as EAR99 for export control purposes.
