TAP475K050SCS Equivalent & Substitute Parts

Part Overview

The TAP475K050SCS is a 4.7 µF conformal coated tantalum capacitor rated for 50 V operation, manufactured by KYOCERA AVX in the TAP series. 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. As an active product with ROHS3 compliance, equivalent and substitute parts are identified to support design flexibility, inventory optimization, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TAP475K050SCS are grouped based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Capacitance: 4.7 µF (exact match required)
• Voltage Rating: 50 V (exact match required for direct substitution)
• Type: Conformal Coated (maintains environmental protection)
• Mounting Type: Through Hole (maintains PCB compatibility)
• Package / Case: Radial (maintains footprint compatibility)
• Operating Temperature: -55°C ~ 125°C (maintains thermal performance envelope)

Secondary Substitution Criteria (with design consideration):

• Tolerance: ±10% or ±20% (wider tolerance acceptable in non-critical applications)
• ESR: 2.5 Ohm (lower ESR values provide improved performance; higher values acceptable if circuit design permits)

Substitutes are categorized into two groups:

Group 1: Direct Equivalents (Same Voltage Rating - 50 V)

• TAP475M050SCS (KYOCERA AVX): Identical electrical specifications with ±20% tolerance
• 199D475X9050D1V1E3 (Vishay Sprague): Cross-manufacturer equivalent with same voltage and capacitance
• T350G475K050AS (KEMET): Cross-manufacturer equivalent with same voltage and capacitance

Group 2: Lower Voltage Ratings (Not Direct Substitutes)

• TAP475K006SCS (KYOCERA AVX): 6.3 V rating
• TAP475K010SCS (KYOCERA AVX): 10 V rating
• TAP475K016SCS (KYOCERA AVX): 16 V rating
• TAP475M010SCS (KYOCERA AVX): 10 V rating with ±20% tolerance

Lower voltage rated parts are listed as documented substitutes but are not suitable for direct replacement in circuits requiring 50 V operation.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (50 V Applications):

TAP475M050SCS is the primary substitute for TAP475K050SCS. Both parts maintain identical voltage rating, capacitance, ESR, and physical dimensions. The tolerance difference (±20% versus ±10%) is acceptable in applications where capacitance variation within this range does not affect circuit performance. Both parts are ROHS3 compliant and share the same series designation.

199D475X9050D1V1E3 (Vishay Sprague TANTALEX™ 199D series) provides cross-manufacturer equivalence with matching voltage and capacitance ratings. Physical dimensions vary slightly (0.236" diameter versus 0.256"), requiring PCB layout verification. ROHS3 compliance is maintained. ESR specification is not provided; circuit design must accommodate this parameter uncertainty.

T350G475K050AS (KEMET T350 UltraDip II series) offers cross-manufacturer equivalence with matching voltage, capacitance, and ESR specifications. Physical dimensions are comparable (0.248" diameter). However, this part is RoHS non-compliant, making it unsuitable for applications requiring RoHS certification compliance.

For Lower Voltage Applications:

TAP475K006SCS, TAP475K010SCS, TAP475K016SCS, and TAP475M010SCS are not suitable as direct replacements for 50 V applications. These parts are listed as documented substitutes but operate at reduced voltage ratings (6.3 V, 10 V, and 16 V respectively). Use only when circuit design permits operation at lower voltage ratings.

Frequently Asked Questions (FAQ)

Q: Can TAP475M050SCS replace TAP475K050SCS directly?

A: Yes. Both parts share identical voltage rating (50 V), capacitance (4.7 µF), ESR (2.5 Ohm), and physical dimensions. The tolerance difference (±20% versus ±10%) is acceptable in applications where capacitance variation does not affect circuit performance. Both are ROHS3 compliant.

Q: What is the difference between TAP475K050SCS and 199D475X9050D1V1E3?

A: Both parts provide 4.7 µF capacitance at 50 V with ±10% tolerance and conformal coating. Differences include manufacturer (KYOCERA AVX versus Vishay Sprague), physical dimensions (0.256" versus 0.236" diameter), and ESR specification (2.5 Ohm versus not specified). PCB layout verification is required due to dimensional variation.

Q: Why is T350G475K050AS not recommended despite matching electrical specifications?

A: T350G475K050AS is RoHS non-compliant, whereas TAP475K050SCS is ROHS3 compliant. Applications requiring RoHS certification cannot use this substitute.

Q: Can lower voltage rated parts (6.3 V, 10 V, 16 V) be used in place of the 50 V part?

A: No. Lower voltage rated parts are not suitable for direct replacement in circuits requiring 50 V operation. These parts are listed as documented substitutes but operate at reduced voltage ratings and cannot provide equivalent performance in 50 V applications.

Q: What parameters must match for a part to be considered a direct substitute?

A: Direct substitutes must maintain identical capacitance (4.7 µF), voltage rating (50 V), mounting type (through hole), package type (radial), and operating temperature range (-55°C to 125°C). Tolerance and ESR variations are acceptable if circuit design permits.

Q: Are all substitute parts available in the same package dimensions?

A: No. Physical dimensions vary across manufacturers. TAP475K050SCS measures 0.256" diameter, while 199D475X9050D1V1E3 measures 0.236" diameter and T350G475K050AS measures 0.248" diameter. PCB layout verification is required when substituting across manufacturers.
