Parameter Comparison

Engineering Selection Recommendations

Both the TAP684M050SCS and TAP684K050SCS maintain Active product status from KYOCERA AVX and are ROHS3 Compliant with REACH Unaffected classification. Selection between these parts depends on tolerance requirements:

• TAP684M050SCS (±20% Tolerance): Suitable for general-purpose applications where capacitance variation within ±20% is acceptable.
• TAP684K050SCS (±10% Tolerance): Appropriate for circuits requiring tighter capacitance control and improved performance stability.

Both parts share identical electrical characteristics (capacitance, voltage rating, ESR, temperature range) and mechanical specifications (radial through-hole package, physical dimensions, lead spacing), ensuring direct interchangeability at the board level. Compliance certifications are equivalent across both options.

Frequently Asked Questions (FAQ)

Q: Can TAP684K050SCS replace TAP684M050SCS in existing designs?

A: Yes. The TAP684K050SCS is a direct substitute with identical electrical and mechanical specifications. The primary difference is improved capacitance tolerance (±10% versus ±20%), which provides better component value consistency without requiring circuit modifications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts feature the same radial through-hole package with 0.177" diameter (4.50 mm), maximum seated height of 0.295" (7.50 mm), and lead spacing of 0.098" (2.50 mm). PCB footprints are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP684M050SCS and TAP684K050SCS are ROHS3 Compliant and REACH Unaffected, with identical ECCN (EAR99) and HTSUS (8532.21.0040) classifications.

Q: What is the significance of the tolerance difference?

A: Tolerance defines the acceptable range of actual capacitance values. The ±10% tolerance of TAP684K050SCS ensures capacitance remains within a narrower band (0.612 µF to 0.748 µF) compared to the ±20% tolerance of TAP684M050SCS (0.544 µF to 0.816 µF). Applications sensitive to capacitance variation benefit from the tighter tolerance.

Q: Are the thermal and electrical performance characteristics the same?

A: Yes. Both parts operate across -55°C to 125°C, maintain 10 Ohm ESR, and provide 1000 hours lifetime at 85°C. Thermal and electrical performance are equivalent.
