Substitute Part Grouping Explanation

Substitution eligibility for the T22C156K100CSS is determined by strict equivalence across the following critical parameters:

• Capacitance value: 15 µF (exact match required)
• Voltage rating: 100 V (exact match required)
• Tolerance: ±10% (exact match required)
• Type: Hermetically sealed tantalum construction
• ESR specification: 4.6 Ohm @ 120Hz (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Lifetime rating: 2000 Hours @ 125°C (exact match required)
• Mounting type: Surface mount
• Package dimensions: 0.303" L × 0.280" W × 0.299" H maximum (exact match required)
• Series classification: T22
• Regulatory compliance: ROHS3 compliant

The substitute part T22C156K100USS meets all electrical and mechanical parameters specified above, confirming direct functional equivalence within the T22 series.

Parameter Comparison

Engineering Selection Recommendations

Both the T22C156K100CSS and T22C156K100USS are Active product status components manufactured by Vishay Sprague. Selection between these parts is based on availability and supply chain considerations rather than electrical or mechanical performance differences. Both components maintain ROHS3 compliance and identical regulatory certifications. The T22C156K100USS is a direct parametric equivalent suitable for applications where the primary part is unavailable. No design modifications, circuit re-evaluation, or performance testing are required when substituting between these components, as all critical electrical parameters, thermal ratings, and physical dimensions are identical.

Frequently Asked Questions (FAQ)

Q: Can T22C156K100USS be used as a direct replacement for T22C156K100CSS?

A: Yes. Both components are identical across all electrical parameters (capacitance, voltage rating, tolerance, ESR), thermal specifications (operating temperature range, lifetime rating), and physical dimensions (package size and height). No circuit modifications are required.

Q: Are there any differences in regulatory compliance between these parts?

A: Both components are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). Regulatory status is equivalent.

Q: What is the difference between the part numbers T22C156K100CSS and T22C156K100USS?

A: The part numbers differ only in the suffix designation (CSS versus USS). This designation reflects internal Vishay Sprague manufacturing or packaging classification but does not affect electrical performance, mechanical compatibility, or functional operation.

Q: Are these components suitable for high-reliability applications?

A: Both components are hermetically sealed tantalum capacitors with 2000-hour lifetime ratings at 125°C and operate across the extended temperature range of -55°C to 125°C, making them suitable for demanding industrial and aerospace applications.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Identical package dimensions (0.303" L × 0.280" W × 0.299" H maximum) and surface mount configuration ensure mechanical and electrical interchangeability without PCB layout modifications.
