Substitute Part Grouping Explanation

Substitution for the TAP686K016HSB is determined by strict equivalence across the following critical parameters:

• Capacitance value: 68 µF (exact match required)
• Voltage rating: 16 V (exact match required)
• Tolerance: ±10% (exact match required)
• Type: Conformal Coated (exact match required)
• ESR: 1 Ohm (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Lifetime specification: 1000 Hrs @ 85°C (exact match required)
• Mounting type: Through Hole Radial (exact match required)
• Physical dimensions: 0.354" Dia (9.00 mm) and 0.551" (14.00 mm) height (exact match required)
• Compliance: ROHS3 Compliant (exact match required)

The TAP686K016CCS meets all these criteria and is classified as a manufacturer-recommended substitute. The primary difference is the lead spacing specification, which does not affect electrical performance or functional compatibility in applications designed for radial through-hole tantalum capacitors.

Parameter Comparison

Engineering Selection Recommendations

Both the TAP686K016HSB and TAP686K016CCS are active production components manufactured by KYOCERA AVX with full ROHS3 compliance. Selection between these parts should be based on the following factors:

• PCB layout and lead spacing requirements: The TAP686K016HSB features 0.250" (6.35 mm) lead spacing, while the TAP686K016CCS features 0.197" (5.00 mm) lead spacing. PCB design must accommodate the selected lead spacing.
• Supply availability: The TAP686K016CCS currently has higher inventory (1582 Pcs) compared to the TAP686K016HSB (924 Pcs).
• All other electrical and mechanical specifications are identical, ensuring functional equivalence in applications designed for 68 µF, 16 V conformal coated radial tantalum capacitors.

Frequently Asked Questions (FAQ)

Q: Can TAP686K016CCS be used as a direct replacement for TAP686K016HSB?

A: Yes, provided the PCB layout accommodates the different lead spacing. The TAP686K016CCS has 0.197" (5.00 mm) lead spacing versus 0.250" (6.35 mm) for the TAP686K016HSB. All electrical parameters, physical dimensions, and compliance certifications are identical.

Q: What is the significance of lead spacing in substitution?

A: Lead spacing determines the distance between the two leads on the component. PCB through-hole pad spacing must match the selected part's lead spacing. Mismatched lead spacing will result in assembly incompatibility.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both TAP686K016HSB and TAP686K016CCS operate across -55°C to 125°C with identical lifetime specifications of 1000 Hrs @ 85°C.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes.

Q: What determines whether a part can substitute for TAP686K016HSB?

A: Substitution requires exact matching of capacitance (68 µF), voltage rating (16 V), tolerance (±10%), type (conformal coated), ESR (1 Ohm), operating temperature range (-55°C to 125°C), lifetime specification (1000 Hrs @ 85°C), mounting type (through hole radial), physical dimensions (0.354" Dia, 0.551" height), and compliance status (ROHS3). Lead spacing may differ if PCB design permits.
