Substitute Part Grouping Explanation

Substitution of the T322C156K015AS is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 15 µF (exact match required)
• Voltage Rating: 15 V (exact match required)
• Tolerance: ±10% (exact match required)
• ESR: 2.5 Ohm (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Package Type: Axial through-hole (exact match required)
• Physical Dimensions: 0.180" Dia x 0.345" L (exact match required)
• Manufacturer Series: T322 (exact match required)

The substitute part T322C156K015AT meets all electrical and mechanical parameters identical to the main part. The primary distinction between these parts is regulatory compliance status: the substitute achieves ROHS3 compliance, whereas the main part is RoHS non-compliant.

Parameter Comparison

Engineering Selection Recommendations

T322C156K015AS is appropriate for applications where RoHS compliance is not a requirement and existing inventory or legacy design specifications mandate this exact part number.

T322C156K015AT is the direct substitute for applications requiring ROHS3 compliance. Both parts are Active status products from KEMET and maintain identical electrical performance, thermal characteristics, and physical form factor. The substitute part provides regulatory compliance advantage while preserving all functional equivalence across capacitance, voltage rating, ESR, and operating temperature specifications.

Selection between these parts should be based on regulatory requirements applicable to the end application and procurement policies governing component selection.

Frequently Asked Questions (FAQ)
