Substitute Part Grouping Explanation

Substitution eligibility for the TAP684M035HSB is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.68 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 35 V (exact match required)
• Type: Conformal Coated (exact match required)
• ESR: 10 Ohm (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Lifetime @ Temperature: 1000 Hrs @ 85°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Manufacturer Size Code: A (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The TAP684M035CCS meets all substitution criteria. Mechanical variations in lead spacing (0.197" vs. 0.250") are permissible within radial through-hole design constraints and do not affect electrical performance or functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both TAP684M035HSB and TAP684M035CCS are Active product status components manufactured by KYOCERA AVX with identical electrical specifications and thermal performance characteristics. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications.

Selection between these parts is determined by availability and lead spacing accommodation in the printed circuit board design. The TAP684M035CCS offers higher inventory availability (3709 pcs vs. 881 pcs) while maintaining full electrical and mechanical equivalence. Lead spacing variation from 0.250" to 0.197" is within standard radial through-hole design tolerances and does not impact circuit performance or reliability.

Frequently Asked Questions (FAQ)

Q: Are TAP684M035HSB and TAP684M035CCS electrically interchangeable?

A: Yes. Both parts share identical capacitance (0.68 µF), tolerance (±20%), voltage rating (35 V), ESR (10 Ohm), operating temperature range (-55°C ~ 125°C), and lifetime specifications (1000 Hrs @ 85°C). Electrical performance is equivalent.

Q: What is the difference between these two part numbers?

A: The primary difference is lead spacing. TAP684M035HSB has 0.250" (6.35 mm) lead spacing, while TAP684M035CCS has 0.197" (5.00 mm) lead spacing. Both are radial through-hole configurations with identical body dimensions (0.177" diameter, 0.335" maximum height).

Q: Can I use TAP684M035CCS as a direct replacement for TAP684M035HSB on an existing PCB?

A: Lead spacing compatibility must be verified against the PCB footprint. If the PCB is designed for 0.250" spacing, the 0.197" spacing of TAP684M035CCS may not align with existing holes. PCB layout review is required before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP684M035HSB and TAP684M035CCS are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: Which part should I select for new designs?

A: Selection is based on PCB footprint requirements and lead spacing accommodation. Both parts are Active status with equivalent performance. Verify lead spacing compatibility with your circuit board design before component selection.
