TS120 Telecom Interface IC Equivalent & Substitute Parts

Part Overview

The TS120 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 two circuits, designed for telecom applications with 800 mW power dissipation and an operating temperature range of -40°C to 85°C. The TS120 is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS120 is determined by strict equivalence across the following 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
• Compliance Standards: ROHS3 Compliant, REACH Unaffected, EAR99 classification
• Moisture Sensitivity: MSL 1 (Unlimited)

The substitute parts TS117L and TS117 meet all these criteria and are classified as active products, providing direct functional and physical compatibility with the obsolete TS120.

Parameter Comparison

Engineering Selection Recommendations

Both TS117L and TS117 are direct parametric equivalents to the obsolete TS120. Selection between these substitutes should be based on the following factors:

TS117L (IXYS Integrated Circuits Division): Maintains the original manufacturer lineage from IXYS. This part is active and available with 2112 units in stock. It carries identical compliance certifications and electrical specifications to the TS120.

TS117 (Littelfuse): Provides equivalent functionality and specifications with 1114 units in stock. This part represents a cross-manufacturer substitute while maintaining full parametric compatibility and compliance requirements.

Both parts are ROHS3 compliant, REACH unaffected, and classified under EAR99 export control. The choice between TS117L and TS117 depends on supply chain preferences, inventory availability, and existing qualification requirements within your organization.

Frequently Asked Questions (FAQ)

Q: Can TS117L and TS117 be used interchangeably with TS120?

A: Yes. Both TS117L and TS117 are parametric equivalents with identical electrical specifications, power dissipation, operating temperature range, and 8-DIP package configuration. They are direct substitutes for the obsolete TS120.

Q: What is the difference between TS117L and TS117?

A: TS117L is manufactured by IXYS Integrated Circuits Division, while TS117 is manufactured by Littelfuse. Both parts are functionally identical with the same electrical and mechanical specifications. The primary difference is manufacturer and packaging format (TS117L supplied in Tube, TS117 supplied in Tube).

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

A: No. All three parts (TS120, TS117L, and TS117) share identical compliance status: ROHS3 compliant, REACH unaffected, EAR99 classification, and MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can I use these parts in new designs?

A: Yes. TS117L and TS117 are both active products and suitable for new design implementations. The TS120 is obsolete and should not be specified for new designs.

Q: What is the pin configuration compatibility?

A: All three parts use the 8-DIP (0.300", 7.62mm) package with identical through-hole mounting. Pin-to-pin compatibility is maintained across all substitutes.

Q: Are there any thermal or power handling differences?

A: No. All parts dissipate 800 mW and operate across the identical temperature range of -40°C to 85°C.
