Substitute Part Grouping Explanation

Substitute parts for the TAP685M050CCSY are classified into two categories based on electrical parameter compatibility:

Direct Equivalent (TAP685M050CCS): This substitute maintains identical electrical specifications across all critical parameters: 6.8 µF capacitance, ±20% tolerance, 50 V rated voltage, 2 Ohm ESR, conformal coated type, and radial through-hole mounting. The only distinction is packaging format (Bulk). This part is interchangeable without circuit redesign.

Voltage-Reduced Substitute (TAP685M016CCS): This substitute maintains capacitance (6.8 µF), tolerance (±20%), conformal coating type, and radial through-hole mounting. However, it operates at a reduced rated voltage of 16 V with increased ESR of 4 Ohm and smaller physical dimensions (0.197" diameter vs. 0.276" diameter). This substitute is applicable only in circuits where the maximum operating voltage does not exceed 16 V and where the increased ESR is acceptable for the application.

Parameter Comparison

Engineering Selection Recommendations

TAP685M050CCS is the primary substitute for TAP685M050CCSY. Both parts are manufactured by KYOCERA AVX, maintain Active product status, and are ROHS3 compliant. Electrical and mechanical specifications are identical, ensuring direct circuit compatibility without design modification. This substitute is recommended when TAP685M050CCSY availability is constrained.

TAP685M016CCS is applicable only when circuit design permits operation at 16 V maximum rated voltage and when the increased ESR of 4 Ohm does not degrade circuit performance. The reduced physical dimensions may provide space savings in compact layouts. This substitute requires circuit-level voltage verification before implementation. All three parts maintain ROHS3 compliance and Active product status, supporting regulatory and supply chain continuity requirements.

Frequently Asked Questions (FAQ)

Q: Can TAP685M050CCS be used as a direct replacement for TAP685M050CCSY?

A: Yes. TAP685M050CCS is a direct equivalent with identical electrical specifications (6.8 µF, ±20%, 50 V, 2 Ohm ESR) and mechanical dimensions. No circuit redesign is required.

Q: Under what conditions can TAP685M016CCS be substituted?

A: TAP685M016CCS can be used only when the circuit maximum operating voltage does not exceed 16 V. The increased ESR (4 Ohm vs. 2 Ohm) must be evaluated for compatibility with ripple current and thermal performance requirements. The smaller physical dimensions (0.197" diameter vs. 0.276" diameter) are compatible with radial through-hole PCB layouts.

Q: What are the key differences between TAP685M016CCS and the main part?

A: TAP685M016CCS differs in three parameters: rated voltage (16 V vs. 50 V), ESR (4 Ohm vs. 2 Ohm), and physical size (0.197" diameter vs. 0.276" diameter). Capacitance, tolerance, temperature range, and mounting type remain identical.

Q: Are all three parts ROHS3 compliant?

A: Yes. TAP685M050CCSY, TAP685M050CCS, and TAP685M016CCS are all ROHS3 compliant and maintain Active product status.

Q: What is the lead spacing for these radial capacitors?

A: All three parts have a lead spacing of 0.197" (5.00mm), ensuring compatibility with standard through-hole PCB footprints.
