Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TS117LS is determined by strict alignment of 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
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Product Status: Active

The TS117S meets all substitution criteria as a parametric equivalent, sharing identical electrical specifications, thermal operating range, package configuration, and compliance certifications with the TS117LS.

Parameter Comparison

Engineering Selection Recommendations

Both TS117LS and TS117S are active products with identical compliance profiles. Selection between these parts may be based on inventory availability and supply chain considerations. The TS117LS currently maintains 2478 pieces in stock, while the TS117S maintains 2120 pieces. Both parts carry ROHS3 compliance and REACH unaffected status, making them suitable for applications subject to environmental and regulatory requirements. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can TS117S replace TS117LS in existing designs? A: Yes. The TS117S is a parametric equivalent with identical electrical specifications, thermal operating range, package configuration, and compliance certifications. Direct substitution is supported without design modification.

Q: Are there differences in package dimensions between TS117LS and TS117S? A: No. Both parts use the 8-SMD, Gull Wing package with identical supplier device package designation. PCB layout and footprint compatibility are maintained.

Q: What is the significance of the MSL rating for these parts? A: The MSL rating of 1 (Unlimited) indicates these components have no moisture sensitivity limitations. Standard storage and handling procedures apply without special moisture control requirements.

Q: Do both parts meet the same regulatory standards? A: Yes. Both TS117LS and TS117S are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements.

Q: What is the operating temperature range for these relay switch ICs? A: Both parts operate across -40°C to 85°C, supporting applications in industrial and telecommunications environments with extended temperature requirements.
