TAP684K035CCS Equivalent & Substitute Parts

Part Overview

The TAP684K035CCS is a 0.68 µF conformal coated tantalum capacitor rated for 35 V with ±10% tolerance, manufactured by KYOCERA AVX. This radial through-hole component is designed for general-purpose applications requiring stable capacitance performance across the operating temperature range of -55°C to 125°C. The part is currently in active production status with ROHS3 compliance and REACH unaffected certification. Substitute parts are identified when equivalent electrical and mechanical specifications are maintained within the allowed parameter tolerances for this product category.

Substitute Part Grouping Explanation

Substitution eligibility for the TAP684K035CCS is determined by the following critical parameters:

• Capacitance Value: Must be 0.68 µF
• Voltage Rating: Must be 35 V or higher
• Tolerance: Acceptable range is ±10% to ±20% (wider tolerance acceptable for substitution)
• Type: Conformal coated tantalum construction required
• ESR: 10 Ohm specification
• Mounting Configuration: Through hole radial package only
• Physical Dimensions: 0.177" diameter (4.50 mm), 0.335" maximum height (8.50 mm), 0.197" lead spacing (5.00 mm)
• Compliance: ROHS3 compliant, REACH unaffected

The TAP684M035CCS qualifies as a direct substitute because it maintains identical capacitance, voltage rating, ESR, physical dimensions, mounting type, and compliance certifications. The tolerance specification differs at ±20%, which is a wider tolerance band and remains within acceptable substitution parameters for this component category.

Parameter Comparison

Engineering Selection Recommendations

Both the TAP684K035CCS and TAP684M035CCS are active production components from KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. The primary distinction is tolerance specification: the main part offers ±10% tolerance while the substitute provides ±20% tolerance. Both components maintain identical electrical performance characteristics, physical dimensions, and thermal ratings. Selection between these parts depends on circuit-level tolerance requirements. Applications requiring tighter capacitance accuracy should specify the TAP684K035CCS. Applications where wider tolerance is acceptable may utilize the TAP684M035CCS, which offers greater inventory availability (3709 units in stock versus 826 units).

Frequently Asked Questions (FAQ)

Q: Can TAP684M035CCS replace TAP684K035CCS in all applications?

A: Substitution is valid when circuit design tolerates ±20% capacitance variation. The TAP684M035CCS maintains all other electrical and mechanical specifications identically. Review circuit tolerance requirements before substitution.

Q: What is the difference between ±10% and ±20% tolerance?

A: Tolerance defines the acceptable capacitance deviation from the nominal 0.68 µF value. ±10% allows 0.612 µF to 0.748 µF; ±20% allows 0.544 µF to 0.816 µF. Wider tolerance may impact circuit performance in precision applications.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical radial package dimensions: 0.177" diameter (4.50 mm), 0.335" maximum seated height (8.50 mm), and 0.197" lead spacing (5.00 mm). PCB layout and mounting procedures are interchangeable.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both TAP684K035CCS and TAP684M035CCS are ROHS3 compliant and REACH unaffected, meeting identical regulatory standards.

Q: What is the ESR specification and why does it matter?

A: Equivalent Series Resistance (ESR) is 10 Ohm for both parts. ESR affects ripple current handling and frequency response. Identical ESR ensures equivalent performance in filtering and decoupling applications.
