TAP475K050GSB Equivalent & Substitute Parts

Part Overview

The TAP475K050GSB is a 4.7 µF conformal coated tantalum capacitor rated at 50 V with radial through-hole mounting. This component is manufactured by KYOCERA AVX and maintains Active product status. Substitute parts become necessary when the original specification is unavailable, inventory constraints exist, or application requirements permit operation at lower voltage ratings while maintaining identical capacitance and tolerance specifications.

Substitute Part Grouping Explanation

Substitution of the TAP475K050GSB is permissible only when the following conditions are met:

• Capacitance value remains 4.7 µF
• Tolerance remains ±10%
• Voltage rating is equal to or greater than the circuit requirement (not exceeding 50 V in the original application)
• Type remains Conformal Coated
• Mounting type remains Through Hole
• Package remains Radial
• Operating temperature range encompasses -55°C ~ 125°C
• RoHS3 compliance is maintained

The TAP475K016GSB qualifies as a substitute only in applications where the circuit voltage requirement does not exceed 16 V. This part shares identical capacitance, tolerance, coating type, mounting configuration, and temperature range with the main part.

Parameter Comparison

Engineering Selection Recommendations

Selection between TAP475K050GSB and TAP475K016GSB is determined by circuit voltage requirements:

• Use TAP475K050GSB when circuit voltage exceeds 16 V and does not exceed 50 V
• Use TAP475K016GSB only when circuit voltage requirement is 16 V or lower

Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment. Both are Active products from KYOCERA AVX with identical capacitance, tolerance, and temperature operating range. The TAP475K016GSB exhibits higher ESR (5 Ohm versus 2.5 Ohm) and smaller physical dimensions, which may affect circuit performance in applications sensitive to series resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Can TAP475K016GSB replace TAP475K050GSB in all applications?

A: No. TAP475K016GSB is suitable only for applications where the circuit voltage requirement does not exceed 16 V. The 50 V rating of the main part cannot be downgraded without circuit analysis.

Q: What is the physical size difference between these parts?

A: TAP475K050GSB has a diameter of 0.256" (6.50mm) and height of 0.453" (11.50mm). TAP475K016GSB has a diameter of 0.177" (4.50mm) and height of 0.354" (9.00mm). Both maintain identical lead spacing of 0.125" (3.18mm).

Q: Do both parts have the same temperature operating range?

A: Yes. Both TAP475K050GSB and TAP475K016GSB operate across -55°C to 125°C with 1000 hours lifetime at 85°C.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH Unaffected, and classified under ECCN EAR99 with identical HTSUS code 8532.21.0040.

Q: Why does TAP475K016GSB have higher ESR?

A: ESR differences result from internal design variations between voltage ratings. TAP475K050GSB has 2.5 Ohm ESR while TAP475K016GSB has 5 Ohm ESR. Applications requiring low ESR performance must use the 50 V rated part.
