TS122 Telecom Interface IC Equivalent & Substitute Parts

Part Overview

The TS122 is a telecom interface IC relay switch in 8-DIP packaging manufactured by IXYS Integrated Circuits Division. This component functions as a relay switch with 2 circuits and 800 mW power dissipation, designed for through-hole mounting in telecom applications. The TS122 is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support, maintenance, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TS122 is determined by strict equivalence across the following critical parameters:

• Function: Relay Switch (2 circuits)
• Power Dissipation: 800 mW
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 8-DIP (0.300", 7.62mm)
• Mounting Method: Through Hole
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must match all these parameters to ensure functional and mechanical compatibility. The TS122 has two identified substitutes: TS117 (manufactured by Littelfuse) and TS117L (manufactured by IXYS Integrated Circuits Division). Both parts satisfy all critical parameter requirements and are available in active product status.

Parameter Comparison

Engineering Selection Recommendations

Both TS117 and TS117L are valid substitutes for the obsolete TS122, with selection based on product availability and compliance requirements:

TS117 (Littelfuse): This direct manufacturer equivalent is actively produced and carries ROHS3 compliance certification. It is suitable for new designs and applications requiring RoHS compliance documentation.

TS117L (IXYS Integrated Circuits Division): This parametric equivalent maintains the original manufacturer lineage and is actively produced with ROHS3 compliance. It is appropriate for applications prioritizing manufacturer continuity or existing supply chain relationships with IXYS.

Both substitutes maintain identical electrical and mechanical specifications, REACH compliance status, and export classification (EAR99). Selection between TS117 and TS117L should be based on procurement availability, packaging preference (both supplied in Tube), and inventory levels.

Frequently Asked Questions (FAQ)

Q: Can TS117 or TS117L be used as direct replacements for TS122 in existing designs?

A: Yes. Both TS117 and TS117L are parametric equivalents matching all critical specifications: 2-circuit relay switch function, 800 mW power dissipation, -40°C to 85°C operating range, 8-DIP through-hole package, and MSL 1 rating. No circuit modifications are required.

Q: What is the difference between TS117 and TS117L?

A: TS117 is manufactured by Littelfuse, while TS117L is manufactured by IXYS Integrated Circuits Division. Both are functionally and mechanically identical. TS117L is designated as a parametric equivalent with TS117 as its base product number. Selection depends on supplier availability and procurement preferences.

Q: Are both substitutes RoHS compliant?

A: Yes. Both TS117 and TS117L carry ROHS3 compliance certification, meeting current environmental and regulatory requirements.

Q: What packaging formats are available for the substitute parts?

A: Both TS117 and TS117L are supplied in Tube packaging, consistent with standard handling and storage practices for 8-DIP components.

Q: Are there any compliance or export restrictions on these parts?

A: No. All three parts (TS122, TS117, TS117L) share identical REACH compliance status (REACH Unaffected) and export classification (EAR99), ensuring no additional regulatory considerations for substitution.
