Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAP474M035SCS is determined by the following criteria:

Tolerance Upgrade (±20% to ±10%): TAP474K035SCS provides identical electrical and mechanical specifications with improved tolerance performance while maintaining the same 35 V voltage rating and physical footprint.

Voltage Rating Upgrade (35 V to 50 V): TAP474K050SCS and TAP474M050SCS both increase the voltage rating to 50 V, providing additional design margin. TAP474K050SCS combines the voltage upgrade with ±10% tolerance, while TAP474M050SCS maintains ±20% tolerance. Both preserve the 0.47 µF capacitance, 13 Ohm ESR, and identical physical dimensions.

All substitute parts share the same capacitance value, ESR, package type, physical dimensions, lead spacing, operating temperature range, and compliance certifications as the primary part.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Same Voltage Rating): TAP474K035SCS is a direct substitute when tighter capacitance tolerance (±10%) is required while maintaining the 35 V rating. All mechanical and thermal characteristics remain identical.

Voltage Upgrade Path: TAP474K050SCS and TAP474M050SCS are suitable when circuit design permits operation at higher voltage ratings. The 50 V rating provides additional safety margin in applications where supply voltage stability or transient protection is a design consideration. Both parts maintain identical physical footprints and thermal performance.

Compliance Alignment: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and identical operating temperature ranges (-55°C to 125°C) and lifetime ratings (1000 Hrs @ 85°C).

Frequently Asked Questions (FAQ)

Q: Can TAP474K035SCS replace TAP474M035SCS in existing designs? A: Yes. TAP474K035SCS is a direct mechanical and electrical substitute with improved tolerance specification (±10% versus ±20%). No PCB layout changes are required.

Q: What is the primary difference between TAP474K050SCS and TAP474M050SCS? A: Both parts have identical voltage ratings (50 V) and physical dimensions. The difference is tolerance: TAP474K050SCS offers ±10% tolerance while TAP474M050SCS offers ±20% tolerance.

Q: Are the 50 V rated parts physically compatible with the 35 V design? A: Yes. TAP474K050SCS and TAP474M050SCS have identical physical dimensions (4.50mm diameter, 7.00mm height, 2.50mm lead spacing) and can be used as direct board-level replacements.

Q: Do all substitute parts have the same ESR specification? A: Yes. All parts listed maintain 13 Ohm ESR, ensuring equivalent performance in high-frequency filtering and transient response applications.

Q: What inventory considerations apply to these substitutes? A: TAP474M035SCS has the highest inventory (17,300 Pcs). If supply constraints occur, TAP474M050SCS (3,445 Pcs) offers the best alternative availability with identical tolerance and only a voltage rating increase.
