Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TIL111SM are identified based on strict electrical and mechanical parameter equivalence. The following criteria determine substitutability:

Critical Parameters for Substitution:

• Single-channel configuration with transistor output and base connection
• Isolation voltage of 7.5Vpk
• Current transfer ratio minimum of 20% @ 16mA
• Maximum output voltage of 30V
• Maximum output current per channel of 50mA
• Forward voltage (Vf) of 1.2V typical
• Maximum DC forward current of 60mA
• Vce saturation maximum of 400mV
• Operating temperature range of -55°C to 100°C
• 6-pin surface mount package with gull wing configuration
• ROHS3 compliance and MSL Level 1 rating

All identified substitutes maintain identical electrical performance specifications and mechanical compatibility with the TIL111SM.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TIL111SM, TIL111XSM, and TIL114XSM—are active products with full ROHS3 compliance and MSL Level 1 rating. Selection between these parts is based on inventory availability and supply chain requirements rather than electrical or mechanical differences.

TIL111SM offers the highest inventory level at 12,100 pieces, making it the primary choice for new designs and high-volume applications.

TIL111XSM and TIL114XSM are direct functional equivalents with lower inventory levels (732 and 987 pieces respectively) and serve as alternatives when primary part availability is constrained.

All parts are certified for the same regulatory and environmental standards, ensuring interchangeability in applications requiring ROHS3 compliance and unlimited moisture sensitivity handling.

Frequently Asked Questions (FAQ)

Q: Can TIL111XSM be used as a direct replacement for TIL111SM?

A: Yes. TIL111XSM is a parametric equivalent with identical electrical specifications, output characteristics, isolation voltage, current transfer ratio, and 6-pin surface mount package configuration. No circuit modifications are required.

Q: What is the difference between TIL111SM and TIL114XSM?

A: Both parts share identical electrical performance parameters, isolation voltage, output current capability, and package format. The difference in series designation (TIL111 vs TIL114) does not affect functional compatibility in applications meeting the specified electrical requirements.

Q: Are all three parts suitable for the same PCB layout?

A: Yes. All three parts use the 6-SMD gull wing package configuration with identical pin assignments and mechanical dimensions, allowing direct footprint compatibility without layout modifications.

Q: What compliance certifications apply to these parts?

A: All three parts are ROHS3 compliant, REACH unaffected, and rated MSL Level 1 (unlimited moisture sensitivity). They carry ECCN classification EAR99 and HTSUS code 8541.49.8000.

Q: Which part should be selected for new designs?

A: TIL111SM is recommended for new designs due to highest inventory availability. TIL111XSM and TIL114XSM serve as qualified alternatives when supply constraints require substitution.
