TAP476J035HSB Equivalent & Substitute Parts

Part Overview

The TAP476J035HSB is a 47 µF conformal coated tantalum capacitor rated for 35 V with ±5% tolerance, manufactured by KYOCERA AVX. This component is designed for through-hole radial mounting applications requiring stable capacitance performance across the operating temperature range of -55°C to 125°C. The part maintains an active product status with 990 units currently in stock. Substitute parts are identified when inventory constraints, lead time requirements, or design flexibility permit tolerance relaxation while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the TAP476J035HSB is determined by strict equivalence in the following parameters:

• Capacitance value: 47 µF (exact match required)
• Voltage rating: 35 V (exact match required)
• Type: Conformal coated tantalum (exact match required)
• ESR: 800 mOhm (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Mounting type: Through hole radial (exact match required)
• Physical dimensions: 0.354" Dia (9.00 mm), height 0.630" (16.00 mm), lead spacing 0.250" (6.35 mm) (exact match required)

The tolerance parameter (±5% for the main part) is the only electrical specification that may vary in approved substitutes. The TAP476M035HSB qualifies as a substitute because it maintains all critical electrical and mechanical parameters while offering a relaxed tolerance of ±20%.

Parameter Comparison

Engineering Selection Recommendations

Both the TAP476J035HSB and TAP476M035HSB maintain active product status with KYOCERA AVX and are ROHS3 compliant. The primary distinction is tolerance specification: the main part offers ±5% tolerance, while the substitute offers ±20% tolerance. Selection between these parts should be based on circuit design requirements for capacitance accuracy. Applications requiring tighter tolerance control must use the TAP476J035HSB. Applications where capacitance variation within ±20% is acceptable may use the TAP476M035HSB, which offers higher inventory availability (1321 units versus 990 units).

Frequently Asked Questions (FAQ)

Q: Can TAP476M035HSB replace TAP476J035HSB in all applications?

A: Substitution is valid only when the circuit design permits capacitance tolerance of ±20%. If the application requires ±5% tolerance accuracy, the TAP476J035HSB must be used.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical radial package dimensions: 0.354" diameter (9.00 mm), maximum seated height of 0.630" (16.00 mm), and lead spacing of 0.250" (6.35 mm). Direct board-level substitution is mechanically compatible.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP476J035HSB and TAP476M035HSB are ROHS3 compliant and maintain identical electrical specifications for voltage rating (35 V), capacitance value (47 µF), ESR (800 mOhm), and operating temperature range (-55°C to 125°C).

Q: What is the difference in ESR between these parts?

A: There is no difference. Both parts maintain 800 mOhm ESR, ensuring equivalent performance in high-frequency filtering and transient response applications.

Q: Are there inventory or lead time advantages to using the substitute?

A: The TAP476M035HSB has higher current inventory (1321 units) compared to the TAP476J035HSB (990 units), which may provide lead time advantages in supply-constrained situations.
