TAP685K050SCS Equivalent & Substitute Parts

Part Overview

The TAP685K050SCS 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 part of the active TAP series and is ROHS3 compliant. Substitute parts may be required due to inventory constraints, application voltage derating requirements, or design optimization for lower voltage applications where the 50 V rating exceeds system needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TAP685K050SCS is permissible with the following TAP series alternatives based on these critical parameters:

Allowed Substitution Parameters:

• Capacitance: 6.8 µF (fixed, no variation)
• Tolerance: ±10% (fixed, no variation)
• Type: Conformal Coated (fixed, no variation)
• Operating Temperature Range: -55°C ~ 125°C (fixed, no variation)
• Mounting Type: Through Hole Radial (fixed, no variation)
• Series: TAP (fixed, no variation)
• Product Status: Active (fixed, no variation)
• RoHS Status: ROHS3 Compliant (fixed, no variation)

Variable Parameters Defining Substitutes:

• Voltage - Rated: 6.3 V, 10 V, 16 V (lower voltage ratings acceptable for applications not requiring 50 V)
• ESR (Equivalent Series Resistance): 2 Ohm to 8 Ohm (varies inversely with voltage rating)
• Physical Dimensions: Size code H (7.00mm diameter) down to size code A (4.50mm diameter)

All substitute parts maintain identical electrical characteristics (capacitance, tolerance, temperature range, lifetime) and compliance certifications while offering lower voltage ratings and corresponding physical size reductions.

Parameter Comparison

Engineering Selection Recommendations

Selection among TAP685K050SCS and its substitutes is determined by circuit voltage requirements and physical space constraints:

TAP685K050SCS (50 V): Use when circuit voltage reaches or approaches 50 V. Provides maximum voltage margin and lowest ESR (2 Ohm). Largest physical footprint (7.00mm diameter, 10.50mm height).

TAP685K016SCS (16 V): Use for circuits operating at 16 V or lower. Reduces physical size to 5.00mm diameter with 8.50mm height. ESR of 4 Ohm remains suitable for general purpose applications. All parts maintain ROHS3 compliance and Active product status.

TAP685K010SCS (10 V): Use for circuits operating at 10 V or lower. Further reduces physical footprint to 4.50mm diameter with 7.50mm height. ESR of 6 Ohm acceptable for applications not requiring minimum impedance. Highest inventory availability (2772 pcs).

TAP685K006SCS (6.3 V): Use for circuits operating at 6.3 V or lower. Smallest physical footprint (4.50mm diameter, 7.00mm height). Highest ESR (8 Ohm) among substitutes. Select only when voltage constraint and space optimization are both critical.

All substitute parts are manufactured by KYOCERA AVX, maintain identical capacitance, tolerance, temperature range, and lifetime specifications, and carry ROHS3 compliance certification.

Frequently Asked Questions (FAQ)

Q: Can TAP685K006SCS replace TAP685K050SCS in any application? A: Only if the circuit operates at 6.3 V or lower. The 6.3 V rating of TAP685K006SCS is the absolute maximum voltage; exceeding this rating will damage the component. Verify circuit voltage before substitution.

Q: What is the impact of different ESR values among these parts? A: ESR varies inversely with voltage rating. TAP685K050SCS has 2 Ohm ESR; TAP685K016SCS has 4 Ohm; TAP685K010SCS has 6 Ohm; TAP685K006SCS has 8 Ohm. Higher ESR increases heat dissipation and impedance. Select based on circuit ripple current and frequency requirements.

Q: Are all substitute parts physically interchangeable on the PCB? A: Lead spacing (0.098" / 2.50mm) is identical across all parts, ensuring PCB footprint compatibility. However, physical dimensions differ: TAP685K050SCS is 7.00mm diameter; TAP685K016SCS is 5.00mm; TAP685K010SCS and TAP685K006SCS are 4.50mm. Verify clearance in the application before substituting with smaller packages.

Q: Do all parts have the same operating temperature range? A: Yes. All parts operate from -55°C to 125°C with 1000 hour lifetime at 85°C. Temperature performance is identical across the TAP series.

Q: What compliance certifications apply to all substitute parts? A: All parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control. All carry HTSUS code 8532.21.0040.

Q: Can I use a higher voltage rated part as a substitute? A: No. Substitution is only permissible with equal or lower voltage ratings. Using a higher voltage part than specified in the design is not a valid substitution.
