Substitute Part Grouping Explanation

The TAP685K035SCS qualifies as a direct substitute for the TAP685M035SLZ based on the following critical parameters:

• Capacitance: Identical at 6.8 µF
• Voltage Rating: Identical at 35 V
• Type: Identical conformal coated construction
• ESR: Identical at 2.5 Ohm
• Operating Temperature: Identical range of -55°C ~ 125°C
• Mounting Type: Identical through-hole radial configuration
• Physical Dimensions: Identical package size and lead spacing
• Compliance: Both ROHS3 compliant and REACH unaffected

The primary difference is tolerance specification: TAP685M035SLZ carries ±20% tolerance, while TAP685K035SCS carries ±10% tolerance. This represents a tighter tolerance specification on the substitute part, making it suitable for applications where the original ±20% tolerance is acceptable or where improved tolerance performance is beneficial.

Parameter Comparison

Engineering Selection Recommendations

Both TAP685M035SLZ and TAP685K035SCS are active production components from KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts depends on tolerance requirements:

• TAP685M035SLZ is appropriate for applications where ±20% capacitance tolerance meets circuit specifications and cost optimization is prioritized.
• TAP685K035SCS is appropriate for applications requiring tighter ±10% capacitance tolerance or where improved tolerance performance provides design margin benefits.

Both parts share identical electrical performance characteristics (ESR, voltage rating, temperature range) and physical form factor, ensuring direct mechanical and electrical interchangeability within the specified tolerance parameters.
