Engineering Selection Recommendations

Both the TAP685M035SCS 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:

  • TAP685M035SCS (±20% tolerance): Suitable for general-purpose applications where standard tolerance specifications are acceptable and cost optimization is a priority.

  • TAP685K035SCS (±10% tolerance): Appropriate for applications requiring tighter capacitance accuracy and improved performance consistency. This substitute offers superior tolerance specification while maintaining identical electrical performance, physical dimensions, and environmental ratings.

Both parts are suitable for through-hole PCB assembly and operate across the full -55°C to 125°C temperature range with equivalent ESR characteristics.

Frequently Asked Questions (FAQ)

Q: Can TAP685K035SCS replace TAP685M035SCS in existing designs?

A: Yes. The TAP685K035SCS is a direct mechanical and electrical substitute. Both parts share identical capacitance (6.8 µF), voltage rating (35 V), ESR (2.5 Ohm), physical dimensions, and thermal specifications. The primary difference is tolerance: TAP685K035SCS provides ±10% tolerance compared to ±20% for the original part.

Q: What is the significance of the tolerance difference?

A: Tolerance defines the acceptable range of actual capacitance values around the nominal 6.8 µF specification. TAP685M035SCS allows values between 5.44 µF and 8.16 µF (±20%), while TAP685K035SCS allows values between 6.12 µF and 7.48 µF (±10%). Tighter tolerance improves circuit performance consistency in applications sensitive to capacitance variation.

Q: Are the physical packages identical?

A: Yes. Both parts use identical radial through-hole packages with Size Code F: 0.236" diameter (6.00mm), maximum seated height of 0.394" (10.00mm), and 0.098" (2.50mm) lead spacing. No PCB layout modifications are required.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP685M035SCS and TAP685K035SCS are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements.

Q: What is the inventory status for each part?

A: TAP685M035SCS has 1316 pieces in stock. TAP685K035SCS has 7493 pieces in stock. Both are listed as new original components.
