TIL117 Optoisolator Transistor Detector - Equivalent & Substitute Parts

Part Overview

The TIL117 is a single-channel optoisolator with transistor output and base connection, designed for DC input applications requiring galvanic isolation up to 7.5Vpk. This component is classified as Active status and remains in production. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or packaging preferences while maintaining identical functional specifications.

Substitute Part Grouping Explanation

Substitute parts for the TIL117 are qualified based on strict electrical and mechanical equivalence across the following critical parameters:

• Single-channel configuration with transistor output and base connection
• Isolation voltage of 7.5Vpk
• Current transfer ratio minimum of 50% @ 10mA
• Maximum output voltage of 30V
• Maximum output current of 50mA per channel
• Forward voltage (Vf) of 1.2V typical
• Maximum forward current (If) of 60mA
• Vce saturation maximum of 400mV
• Operating temperature range of -55°C to 100°C
• 6-DIP through-hole package (0.300", 7.62mm)
• ROHS3 compliance and MSL Level 1 rating

The TIL117X variant meets all electrical specifications and mechanical requirements, differing only in packaging format (Tube versus standard packaging).

Parameter Comparison

Engineering Selection Recommendations

Both TIL117 and TIL117X maintain Active product status and full ROHS3 compliance with MSL Level 1 rating. Selection between these parts is determined by packaging and supply requirements rather than electrical performance. The TIL117X is supplied in Tube packaging, while the standard TIL117 variant accommodates alternative packaging formats. Both components satisfy identical electrical and thermal specifications for DC input optoisolation applications requiring 7.5Vpk isolation voltage and 50mA output current capability.

Frequently Asked Questions (FAQ)

Q: Can TIL117X be used as a direct replacement for TIL117?

A: Yes. The TIL117X is electrically and mechanically equivalent to the TIL117. Both components share identical electrical specifications, operating temperature range, and 6-DIP through-hole package dimensions. The difference is limited to packaging format (Tube for TIL117X).

Q: What determines substitution eligibility for the TIL117?

A: Substitution is valid when the alternative part maintains: single-channel configuration, 7.5Vpk isolation voltage, 50% minimum current transfer ratio @ 10mA, 30V maximum output voltage, 50mA maximum output current, 1.2V typical forward voltage, 60mA maximum forward current, 400mV maximum Vce saturation, -55°C to 100°C operating temperature range, 6-DIP through-hole package, ROHS3 compliance, and MSL Level 1 rating.

Q: Are there any compatibility concerns when substituting TIL117 with TIL117X?

A: No compatibility concerns exist. Both parts are pin-compatible with identical 6-DIP package dimensions (0.300", 7.62mm) and through-hole mounting. Electrical performance is equivalent across all specified parameters.

Q: What is the significance of the packaging difference between TIL117 and TIL117X?

A: The packaging difference (Tube for TIL117X) affects handling, storage, and supply chain logistics but does not impact electrical performance or circuit functionality. Selection depends on assembly process requirements and inventory management preferences.
