TAP475J020SCS Equivalent & Substitute Parts

Part Overview

The TAP475J020SCS is a 4.7 µF conformal coated tantalum capacitor rated at 20 V with ±5% tolerance, manufactured by KYOCERA AVX. This radial through-hole component is designed for general purpose applications requiring reliable performance across industrial temperature ranges. The part is currently active in production with 1016 units in stock.

Substitute parts are identified when equivalent electrical performance can be maintained within the allowed parameter tolerances for the application circuit. Substitution eligibility is determined by matching capacitance value, compatible voltage rating, acceptable tolerance range, and identical mounting and package specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TAP475J020SCS are identified based on the following criteria:

Matching Parameters (Required for Substitution):

• Capacitance value: 4.7 µF (exact match)
• Mounting type: Through Hole (exact match)
• Package type: Radial (exact match)
• Series: TAP (KYOCERA AVX conformal coated tantalum capacitors)
• Product status: Active (current production availability)
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• Voltage rating: Lower voltage ratings are acceptable if the application circuit operates within the substitute part's voltage specification
• Tolerance: Wider tolerance (±10%) is acceptable for general purpose applications where ±5% tolerance is not a circuit requirement
• ESR: Variations in ESR are acceptable provided the substitute part meets the application's ripple current and transient response requirements
• Physical dimensions: Minor variations in case size are acceptable if the substitute part fits within the available board space

The TAP475K006SCS meets all matching parameters and is classified as a manufacturer-recommended substitute.

Parameter Comparison

Engineering Selection Recommendations

TAP475J020SCS (Primary Selection): Use the TAP475J020SCS when the application circuit requires a 20 V rated capacitor with ±5% tolerance. This part provides the specified voltage margin and tighter capacitance tolerance for circuits where these parameters are design requirements.

TAP475K006SCS (Substitute Selection): The TAP475K006SCS is a valid substitute only when all of the following conditions are met:

• The application circuit operates at voltages not exceeding 6.3 V
• The circuit design tolerates ±10% capacitance variation
• The increased ESR of 10 Ohm does not adversely affect circuit performance
• The smaller physical dimensions (4.50mm diameter, 7.00mm height) fit within available board space

Both parts are ROHS3 compliant and maintain identical operating temperature ranges and lifetime specifications. Both are manufactured by KYOCERA AVX and are currently in active production.

Frequently Asked Questions (FAQ)

Q: Can TAP475K006SCS replace TAP475J020SCS in any application?

A: No. The TAP475K006SCS has a lower voltage rating (6.3 V vs. 20 V) and wider tolerance (±10% vs. ±5%). Substitution is only valid when the application circuit operates within 6.3 V and tolerates ±10% capacitance variation.

Q: What is the voltage derating consideration?

A: The TAP475J020SCS is rated for 20 V operation. The TAP475K006SCS is rated for 6.3 V operation. If the application circuit voltage exceeds 6.3 V, the TAP475K006SCS cannot be used as a substitute.

Q: Are the physical dimensions compatible?

A: Both parts use radial through-hole packages with identical 0.098" (2.50mm) lead spacing. The TAP475K006SCS is physically smaller (4.50mm diameter vs. 5.00mm, and 7.00mm height vs. 8.50mm). Verify that the smaller dimensions fit within available board space before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP475J020SCS and TAP475K006SCS are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Q: What is the ESR difference impact?

A: The TAP475K006SCS has higher ESR (10 Ohm vs. 4.5 Ohm). Higher ESR increases impedance at high frequencies and generates more heat under ripple current conditions. Verify that the application circuit can tolerate this ESR increase before substitution.
