TAP685M050CCS-LF Equivalent & Substitute Parts

Part Overview

The TAP685M050CCS-LF is a 6.8 µF conformal coated tantalum capacitor rated for 50 V operation in a radial through-hole package. Manufactured by KYOCERA AVX, this component is classified as Active product status and is ROHS3 compliant. Substitute parts may be required due to inventory constraints, packaging format differences, or application-specific voltage and ESR requirements within the same capacitance and series family.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the TAP series is determined by strict equivalence in the following parameters: capacitance value (6.8 µF), tolerance (±20%), conformal coating type, through-hole radial mounting, operating temperature range (-55°C ~ 125°C), and compliance certifications (ROHS3, REACH Unaffected).

The TAP685M050CCS-LF has two identified substitutes:

Direct Equivalent (TAP685M050CCS): Identical electrical and mechanical specifications. Difference is packaging format only (Bulk vs. Tape & Reel).

Voltage-Reduced Variant (TAP685M016CCS): Maintains capacitance, tolerance, series, and conformal coating. Voltage rating reduced to 16 V and ESR increased to 4 Ohm. Physical dimensions also reduced. This part is suitable only for applications where the 50 V rating is not required and 16 V operation is acceptable.

Parameter Comparison

Engineering Selection Recommendations

TAP685M050CCS is the direct equivalent substitute for TAP685M050CCS-LF. Both parts maintain identical electrical performance and physical dimensions. Selection between them is determined by procurement packaging requirements: TAP685M050CCS-LF is supplied in tape & reel format, while TAP685M050CCS is supplied in bulk. Both are Active status products with full ROHS3 and REACH compliance.

TAP685M016CCS is a voltage-reduced variant suitable only for applications where the circuit operates at 16 V or lower. This part introduces two design changes: reduced voltage rating (16 V vs. 50 V) and increased ESR (4 Ohm vs. 2 Ohm). Physical dimensions are also reduced. Use this substitute only when the application voltage requirement does not exceed 16 V and the higher ESR is acceptable for the circuit design.

Frequently Asked Questions (FAQ)

Q: Can TAP685M050CCS replace TAP685M050CCS-LF directly?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. TAP685M050CCS-LF uses tape & reel packaging, while TAP685M050CCS uses bulk packaging. Selection depends on assembly process requirements.

Q: Can TAP685M016CCS be used as a substitute for TAP685M050CCS-LF?

A: Only if the application circuit operates at 16 V or lower. The TAP685M016CCS has a reduced voltage rating (16 V vs. 50 V) and higher ESR (4 Ohm vs. 2 Ohm). If the circuit requires 50 V operation or the lower ESR is critical for performance, this part is not suitable.

Q: What is the impact of increased ESR in TAP685M016CCS?

A: ESR affects ripple current handling and heat dissipation. The TAP685M016CCS has 4 Ohm ESR compared to 2 Ohm in the main part. This increases impedance and may affect high-frequency performance. Verify circuit requirements before substitution.

Q: Are all three parts ROHS3 compliant?

A: Yes. TAP685M050CCS-LF, TAP685M050CCS, and TAP685M016CCS are all ROHS3 compliant and REACH unaffected.

Q: What are the physical dimension differences?

A: TAP685M050CCS-LF and TAP685M050CCS share identical dimensions: 0.276" diameter (7.00mm) and 0.472" height (12.00mm). TAP685M016CCS is smaller: 0.197" diameter (5.00mm) and 0.394" height (10.00mm). Verify PCB layout compatibility before substitution.
