TS122STR Equivalent & Substitute Parts

Part Overview

The TS122STR is a telecom interface IC relay switch manufactured by IXYS Integrated Circuits Division, designed for telecommunications applications requiring relay switching functionality. This component features 2 circuits in an 8-SMD surface mount package with 800 mW power rating and operates across the -40°C to 85°C temperature range. The TS122STR is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS122STR is determined by equivalence across the following critical parameters:

• Function: Relay Switch
• Number of Circuits: 2
• Power Rating: 800 mW
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount
• Package / Case: 8-SMD, Gull Wing
• Supplier Device Package: 8-SMD
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts TS117LSTR and TS117STR maintain identical functional and electrical specifications while offering active product status and improved compliance certifications. Both substitutes are manufactured by IXYS Integrated Circuits Division and are available in Tape & Reel packaging with higher inventory levels.

Parameter Comparison

Engineering Selection Recommendations

Both TS117LSTR and TS117STR are direct functional equivalents to the obsolete TS122STR. Selection between these two active alternatives should be based on packaging requirements and inventory availability:

TS117LSTR is supplied in Tape & Reel packaging with 2100 units in stock and carries ROHS3 compliance certification.

TS117STR is supplied in Tape & Reel packaging with 6165 units in stock and carries ROHS3 compliance certification.

Both parts maintain identical electrical and mechanical specifications, REACH compliance status, and export classification. The choice between them depends on procurement volume requirements and supply chain considerations rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can TS117LSTR and TS117STR be used interchangeably with TS122STR?

A: Yes. Both parts maintain identical function, circuit count, power rating, operating temperature range, and 8-SMD package configuration. The primary difference is product status: TS122STR is obsolete while TS117LSTR and TS117STR are active.

Q: What is the difference between TS117LSTR and TS117STR?

A: Both parts are functionally and electrically identical. The difference lies in packaging format and inventory levels. TS117STR has higher stock availability (6165 units versus 2100 units).

Q: Are there any compliance differences between the substitute parts and the original TS122STR?

A: TS117LSTR and TS117STR both carry ROHS3 compliance certification, while the original TS122STR does not specify RoHS status. All three parts maintain REACH Unaffected status and EAR99 export classification.

Q: Does the 8-SMD Gull Wing package remain the same across all three parts?

A: Yes. The package configuration, pin count, and physical footprint are identical across TS122STR, TS117LSTR, and TS117STR, ensuring direct PCB compatibility.

Q: What is the Moisture Sensitivity Level for these components?

A: All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
