• Voltage rating: 25 V (exact match required)
• Type: Conformal Coated (exact match required)
• ESR: 4 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 (exact match required)
• Package: Radial (exact match required)
• Physical dimensions: 0.197" Dia (5.00 mm) (exact match required)
• Height: 0.394" (10.00 mm) (exact match required)
• Compliance: RoHS3 Compliant (exact match required)

The TAP475K025CCS meets all substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both TAP475K025HSB and TAP475K025CCS are active production components manufactured by KYOCERA AVX with identical electrical specifications and compliance certifications. Selection between these parts should be based on lead spacing requirements and inventory availability. The TAP475K025HSB features 0.250" (6.35 mm) lead spacing, while the TAP475K025CCS features 0.197" (5.00 mm) lead spacing. PCB layout and hole spacing must accommodate the selected lead spacing. Both parts maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across global markets.
