Key Parameters

Substitute Part Grouping Explanation

Substitution of the TS117L is determined by strict equivalence across the following critical parameters:

• Functional equivalence: Relay switch with identical two-circuit configuration
• Electrical compatibility: 800 mW power rating and -40°C ~ 85°C operating temperature range
• Mechanical compatibility: 8-DIP through-hole package with 0.300" (7.62mm) pitch
• Regulatory compliance: ROHS3 compliance, MSL Level 1, and REACH unaffected status

The TS117 manufactured by Littelfuse meets all these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the TS117L and TS117 are active production components with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Availability: TS117L has 2112 units in stock; TS117 has 1114 units in stock
• Regulatory compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, suitable for regulated applications
• Supply chain considerations: Either part is suitable for direct substitution in existing designs without circuit modification

Frequently Asked Questions (FAQ)

Q: Can the TS117 (Littelfuse) directly replace the TS117L (IXYS) in existing applications?

A: Yes. Both parts are parametric equivalents with identical relay switch function, two-circuit configuration, 800 mW power rating, -40°C ~ 85°C operating temperature range, and 8-DIP through-hole package. No circuit redesign is required.

Q: Are there any differences in package dimensions between these parts?

A: No. Both parts use the 8-DIP package with 0.300" (7.62mm) pitch, ensuring identical PCB footprint compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the TS117L and TS117 are ROHS3 compliant, MSL Level 1, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8541.49.9500.

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

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

Q: Are there any supply chain advantages to choosing one manufacturer over the other?

A: The TS117L currently has higher inventory availability (2112 units) compared to the TS117 (1114 units). Selection should consider project lead times and supply requirements.
