Substitute Part Grouping Explanation

The TAP476M006SCS qualifies as a substitute based on the following allowable parameters:

• Capacitance Match: Both parts maintain 47 µF capacitance
• Tolerance Match: Both parts specify ±20% tolerance
• Type Match: Both are conformal coated tantalum capacitors
• Operating Temperature Match: Both support -55°C ~ 125°C range
• Lifetime Match: Both rated for 1000 Hrs @ 85°C
• Mounting Type Match: Both are through-hole radial packages
• Lead Spacing Match: Both maintain 0.098" (2.50 mm) lead spacing
• Compliance Match: Both are ROHS3 compliant and REACH unaffected

Critical Difference: The TAP476M006SCS is rated for 6.3 V operation versus the primary part's 35 V rating. This substitute is applicable only in circuits where the maximum operating voltage does not exceed 6.3 V.

Parameter Comparison

Engineering Selection Recommendations

The TAP476M035SCS and TAP476M006SCS are both active products from the KYOCERA AVX TAP series with full ROHS3 compliance and REACH unaffected status. Selection between these parts must be determined by circuit voltage requirements. The primary part (TAP476M035SCS) is suitable for applications requiring voltage ratings up to 35 V. The substitute (TAP476M006SCS) is restricted to circuits with maximum operating voltages not exceeding 6.3 V. Both parts maintain identical capacitance, tolerance, temperature range, and lifetime specifications. The substitute exhibits higher ESR (2 Ohm versus 800 mOhm) and smaller physical dimensions, which may affect circuit performance in applications sensitive to series resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Can TAP476M006SCS replace TAP476M035SCS in any application?

A: No. The TAP476M006SCS is rated for maximum 6.3 V operation. It can only substitute in circuits where the applied voltage does not exceed 6.3 V. Using this part in circuits designed for 35 V operation will result in component failure.

Q: Are the physical dimensions compatible between these parts?

A: No. The TAP476M006SCS is physically smaller (0.236" diameter, 0.394" height) compared to the TAP476M035SCS (0.354" diameter, 0.630" height). PCB layout and mechanical clearance must be verified before substitution. Lead spacing remains identical at 0.098" (2.50 mm).

Q: What is the significance of the ESR difference between these parts?

A: The TAP476M006SCS has higher ESR (2 Ohm) compared to the TAP476M035SCS (800 mOhm). In applications where low series resistance is critical for ripple current handling or transient response, this difference may affect circuit performance.

Q: Are both parts RoHS compliant?

A: Yes. Both TAP476M035SCS and TAP476M006SCS are ROHS3 compliant and REACH unaffected.

Q: What is the lead spacing for both parts?

A: Both parts maintain identical lead spacing of 0.098" (2.50 mm), allowing for compatible PCB footprints in terms of hole spacing.
