Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TIL117SM are identified based on strict parametric equivalence across all critical specifications. The substitution logic is based on the following key parameters that must match identically:

• Single channel configuration (Number of Channels: 1)
• Isolation voltage rating (7.5Vpk)
• Current transfer ratio minimum (50% @ 10mA)
• Transistor output with base connection
• Maximum output voltage (30V)
• Output current per channel (50mA)
• Rise and fall time characteristics (2µs, 2µs)
• Vce saturation maximum (400mV)
• Operating temperature range (-55°C ~ 100°C)
• Surface mount package type (6-SMD, Gull Wing)
• Compliance certifications (ROHS3, REACH Unaffected)

All identified substitute parts maintain identical electrical performance and mechanical compatibility with the TIL117SM.

Parameter Comparison

Engineering Selection Recommendations

Both TIL117XSM and H11A1XSM are direct parametric equivalents to the TIL117SM and are suitable for substitution in applications requiring single-channel optoisolation with transistor output. All three parts maintain Active product status and are ROHS3 compliant with REACH Unaffected designation, confirming regulatory compliance for industrial and commercial applications.

Selection between these equivalent parts may be based on inventory availability and lead time considerations. The TIL117XSM maintains the same series designation as the primary part, while the H11A1XSM represents an alternative series from the same manufacturer with identical electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can TIL117XSM and H11A1XSM be used interchangeably with TIL117SM?

A: Yes. Both substitute parts match all critical electrical parameters including isolation voltage, current transfer ratio, output voltage and current ratings, switching characteristics, and operating temperature range. The 6-SMD Gull Wing package is identical across all three parts, enabling direct board-level substitution.

Q: What determines if a part is a valid substitute for TIL117SM?

A: A valid substitute must maintain identical specifications across all key parameters: single-channel configuration, 7.5Vpk isolation voltage, 50% minimum current transfer ratio at 10mA, transistor output with base connection, 30V maximum output voltage, 50mA output current, 2µs rise and fall times, 400mV maximum Vce saturation, -55°C to 100°C operating temperature range, and 6-SMD Gull Wing surface mount package.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and Moisture Sensitivity Level 1 (Unlimited). All parts are classified as Active status.

Q: Does package type affect substitution eligibility?

A: Yes. The package type must be identical for direct substitution. All three parts use the 6-SMD Gull Wing surface mount package, confirming mechanical compatibility and board-level interchangeability.

Q: What is the difference between TIL117SM and TIL117XSM?

A: Both parts belong to the TIL117 series and maintain identical electrical and mechanical specifications. The designation difference reflects packaging or supplier variation but does not affect functional performance or substitution eligibility.
