Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAP334M050SCS is determined by the following critical parameters:

• Capacitance Value: Must be 0.33 µF (exact match required)
• Voltage Rating: Must be 50 V or higher (equal or greater)
• Package Type: Must be radial through-hole with identical lead spacing (0.098" / 2.50mm)
• Physical Dimensions: Must match 0.177" diameter and 0.276" maximum height
• ESR: Must be 15 Ohm (exact match required)
• Operating Temperature Range: Must support -55°C to 125°C
• Conformal Coating: Must be present for environmental protection

The TAP334K050SCS qualifies as a direct substitute because it maintains all critical electrical parameters (capacitance, voltage, ESR, temperature range) and identical mechanical specifications (package, dimensions, lead spacing). The tolerance change from ±20% to ±10% represents an upgrade in accuracy without affecting substitutability.

Parameter Comparison

Engineering Selection Recommendations

Both TAP334M050SCS and TAP334K050SCS are active production components manufactured by KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on tolerance requirements for the specific application. The TAP334K050SCS offers improved tolerance (±10% versus ±20%), making it suitable for circuits requiring tighter capacitance accuracy. Both parts maintain identical electrical performance characteristics (ESR, voltage rating, lifetime rating) and occupy the same physical footprint, ensuring direct PCB compatibility without layout modifications. Inventory availability should also be considered: TAP334K050SCS has 3524 units in stock compared to 1098 units for TAP334M050SCS.

Frequently Asked Questions (FAQ)

Q: Can TAP334K050SCS replace TAP334M050SCS in existing designs?

A: Yes. Both parts share identical capacitance (0.33 µF), voltage rating (50 V), ESR (15 Ohm), package type (radial through-hole), physical dimensions, lead spacing, and operating temperature range. The TAP334K050SCS is a direct substitute with improved tolerance specification.

Q: What is the difference between ±20% and ±10% tolerance?

A: Tolerance defines the acceptable deviation of actual capacitance from the nominal value. TAP334M050SCS allows ±20% deviation (0.264 µF to 0.396 µF), while TAP334K050SCS allows ±10% deviation (0.297 µF to 0.363 µF). Applications requiring precise capacitance values benefit from the tighter tolerance of TAP334K050SCS.

Q: Are the physical packages identical?

A: Yes. Both parts are radial through-hole components with 0.177" diameter (4.50mm), 0.276" maximum seated height (7.00mm), and 0.098" lead spacing (2.50mm). No PCB layout changes are required for substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP334M050SCS and TAP334K050SCS are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which part should I select for new designs?

A: For new designs, TAP334K050SCS is recommended due to superior tolerance accuracy (±10%), higher inventory availability (3524 units), and identical electrical and mechanical specifications. This part provides better long-term supply security and improved circuit performance predictability.
