TAP476M016SLZ Equivalent & Substitute Parts

Part Overview

The TAP476M016SLZ is a 47 µF conformal coated tantalum capacitor rated at 16 V with ±20% tolerance, manufactured by KYOCERA AVX. This radial through-hole component is designed for general-purpose applications requiring reliable energy storage in compact form factors. The part is currently active in production with 772 units in stock. Substitute parts are identified when design requirements permit tolerance relaxation, voltage rating reduction, or when inventory constraints necessitate alternative sourcing while maintaining functional equivalence within specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the TAP476M016SLZ is determined by the following criteria:

Primary Substitution Criteria (Electrical):

• Capacitance value must remain 47 µF
• Voltage rating must be equal to or greater than 16 V
• Tolerance may be tightened (±10% acceptable for ±20% requirement)
• ESR must not exceed 1.3 Ohm
• Operating temperature range must encompass -55°C to 125°C
• Lifetime specification must meet or exceed 1000 Hrs @ 85°C

Secondary Substitution Criteria (Mechanical):

• Mounting type must be Through Hole Radial
• Lead spacing must be 0.098" (2.50 mm)
• Physical dimensions must fit within PCB layout constraints

Compliance Criteria:

• RoHS3 compliance required
• REACH unaffected status required
• ECCN EAR99 classification maintained

Identified Substitute Parts:

1. TAP476K016SCS — Upgrade substitute with tightened tolerance (±10% vs ±20%), same voltage rating (16 V), identical ESR and physical dimensions
2. TAP476M006SCS — Downgrade substitute with reduced voltage rating (6.3 V vs 16 V), same tolerance (±20%), increased ESR (2 Ohm vs 1.3 Ohm), reduced physical dimensions

Engineering Selection Recommendations

TAP476K016SCS Selection Criteria: This upgrade substitute is electrically and mechanically identical to the TAP476M016SLZ with the exception of tolerance specification. The tightened ±10% tolerance provides improved capacitance accuracy while maintaining the same 16 V voltage rating, 1.3 Ohm ESR, and physical footprint. Both parts are ROHS3 compliant and REACH unaffected. Selection of TAP476K016SCS is appropriate when design specifications require tighter capacitance tolerance or when inventory availability of the primary part is constrained. The higher inventory level (3455 units) supports supply chain continuity.

TAP476M006SCS Selection Criteria: This downgrade substitute maintains the same 47 µF capacitance and ±20% tolerance but operates at a reduced voltage rating of 6.3 V compared to the 16 V primary specification. The ESR increases to 2 Ohm, and the physical package is smaller (0.236" diameter vs 0.315" diameter). Selection of TAP476M006SCS is restricted to applications where the circuit voltage does not exceed 6.3 V and where the increased ESR is acceptable for the intended function. The smaller footprint may provide PCB layout advantages in space-constrained designs. Both parts maintain ROHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can TAP476K016SCS directly replace TAP476M016SLZ without circuit modification? A: Yes. TAP476K016SCS is a direct replacement with identical electrical performance at 16 V and 47 µF. The ±10% tolerance is tighter than the ±20% specification of the primary part, making it functionally superior for the same application. No circuit modification is required.

Q: Under what conditions is TAP476M006SCS a valid substitute? A: TAP476M006SCS is valid only when the circuit operating voltage does not exceed 6.3 V. The reduced voltage rating and increased ESR (2 Ohm vs 1.3 Ohm) make this part unsuitable for circuits designed for 16 V operation. The smaller physical dimensions may require PCB layout verification.

Q: Are all substitute parts ROHS3 compliant? A: Yes. Both TAP476K016SCS and TAP476M006SCS are ROHS3 compliant and REACH unaffected, matching the compliance status of the primary TAP476M016SLZ part.

Q: What is the impact of ESR differences between substitute parts? A: The primary part and TAP476K016SCS both specify 1.3 Ohm ESR. TAP476M006SCS specifies 2 Ohm ESR. Higher ESR increases heat dissipation and may affect circuit performance in high-frequency or high-ripple-current applications. Verify ESR compatibility with circuit requirements before selecting TAP476M006SCS.

Q: Do the physical dimensions of TAP476M006SCS affect PCB compatibility? A: Yes. TAP476M006SCS has a smaller package diameter (0.236" vs 0.315") and reduced height (0.394" vs 0.453"). While lead spacing remains 0.098" (2.50 mm), the smaller footprint requires verification that the component fits within the PCB layout constraints of the original design.

Q: What inventory considerations apply to substitute selection? A: TAP476K016SCS has significantly higher inventory (3455 units) compared to the primary part (772 units) and TAP476M006SCS (788 units). Inventory availability may influence substitute selection when supply chain continuity is a priority.
