TS117LSTR Equivalent & Substitute Parts

Part Overview

The TS117LSTR is a telecom interface relay switch IC manufactured by IXYS Integrated Circuits Division. This surface mount component functions as a relay switch with two circuits in an 8-SMD package configuration. The part is currently active in production with 2100 units available in new original stock. Substitute parts become necessary when primary inventory is depleted, when supply chain disruptions occur, or when design flexibility allows for functionally equivalent alternatives from the same manufacturer.

Substitute Part Grouping Explanation

Substitution eligibility for the TS117LSTR is determined by strict equivalence across the following critical parameters:

• Identical base product number (TS117)
• Matching function (Relay Switch)
• Identical number of circuits (2)
• Identical power rating (800 mW)
• Identical operating temperature range (-40°C to 85°C)
• Identical package type (8-SMD, Gull Wing)
• Identical mounting type (Surface Mount)
• Matching RoHS and REACH compliance status
• Identical MSL rating (1 - Unlimited)

The TS117STR meets all substitution criteria as a parametric equivalent within the TS117 product family. Both parts share identical electrical and mechanical specifications, enabling direct substitution in applications where the TS117LSTR is specified.

Parameter Comparison

Engineering Selection Recommendations

Both TS117LSTR and TS117STR are active production parts manufactured by IXYS Integrated Circuits Division with identical compliance certifications. The TS117STR carries higher inventory availability (6165 units) compared to the TS117LSTR (2100 units), making it a viable alternative when supply considerations are relevant. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in applications requiring environmental compliance. Selection between these parts should be based on inventory availability and supply chain requirements, as all electrical and mechanical parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can TS117STR be used as a direct replacement for TS117LSTR?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, power ratings, operating temperature ranges, and 8-SMD package configurations. Direct substitution is supported without circuit modification.

Q: Are there differences in the packaging format between these parts?

A: No. Both TS117LSTR and TS117STR are supplied in Tape & Reel (TR) format with identical 8-SMD, Gull Wing package specifications.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting identical environmental and regulatory standards.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any operational differences between TS117LSTR and TS117STR?

A: No. Both parts operate identically across all specified parameters including power consumption (800 mW), circuit count (2), and temperature range (-40°C to 85°C).
