• Rated Voltage: 25 V (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 @ Temperature: 1000 Hrs @ 85°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Diameter: 0.354" (9.00mm) (exact match required)
• Height - Seated (Max): 0.571" (14.50mm) (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• REACH Status: REACH Unaffected (exact match required)

The TAP476M025CCS qualifies as a direct substitute based on full alignment with all electrical and mechanical parameters listed above. The only variance is in lead spacing, which does not affect electrical performance or functional compatibility in applications designed for the TAP476M025HSB.

Parameter Comparison

Engineering Selection Recommendations

Both TAP476M025HSB and TAP476M025CCS are active production components manufactured by KYOCERA AVX with identical electrical specifications and thermal performance characteristics. Both parts maintain full ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for current and future electronic assemblies.

Selection between these parts should be based on PCB layout requirements. The TAP476M025HSB features 0.250" (6.35mm) lead spacing, while the TAP476M025CCS provides 0.197" (5.00mm) lead spacing. Lead spacing variance affects only the physical footprint on the printed circuit board and does not impact electrical performance, reliability, or functional operation.

Frequently Asked Questions (FAQ)

Q: Can TAP476M025CCS be used as a direct replacement for TAP476M025HSB?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters including capacitance, voltage rating, ESR, temperature range, and reliability specifications. The only difference is lead spacing, which is a PCB layout consideration and does not affect electrical compatibility.

Q: Does lead spacing difference affect circuit performance?

A: No. Lead spacing is a mechanical dimension that determines the distance between solder pads on the printed circuit board. It does not influence capacitance, voltage rating, ESR, frequency response, or any electrical characteristic of the component.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both TAP476M025HSB and TAP476M025CCS operate across the full temperature range of -55°C to 125°C with rated lifetime of 1000 hours at 85°C, meeting requirements for industrial and automotive environments.

Q: What is the significance of conformal coating on these parts?

A: Conformal coating provides environmental protection against moisture, dust, and corrosive atmospheres. Both parts feature identical conformal coating specifications, ensuring equivalent protection in harsh operating conditions.

Q: Are these parts RoHS compliant?

A: Yes. Both TAP476M025HSB and TAP476M025CCS are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for electronic components in regulated markets.

Q: How do I determine which lead spacing is required for my application?

A: Lead spacing is determined by your PCB design and footprint requirements. Verify the distance between solder pads in your circuit board layout. If your design accommodates 0.197" (5.00mm) spacing, TAP476M025CCS is suitable. If your design requires 0.250" (6.35mm) spacing, TAP476M025HSB is the appropriate selection.
