Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAP155M035SLZ is determined by the following criteria:

Electrical Parameters (Must Match):

• Capacitance: 1.5 µF
• Voltage Rating: 35 V
• ESR: 6 Ohm
• Operating Temperature Range: -55°C to 125°C
• Lifetime @ Temperature: 1000 Hrs @ 85°C

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole Radial
• Package Dimensions: 0.177" Dia (4.50mm), Height 0.276" (7.00mm)
• Lead Spacing: 0.098" (2.50mm)

Allowed Variation:

• Tolerance: ±20% to ±10% (tighter tolerance acceptable)

The TAP155K035SCS qualifies as a direct substitute because it maintains identical capacitance, voltage rating, ESR, temperature performance, and physical dimensions while offering improved tolerance specification (±10% versus ±20%).

Parameter Comparison

Engineering Selection Recommendations

Both TAP155M035SLZ and TAP155K035SCS are active products manufactured by KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on tolerance requirements and inventory availability.

The TAP155M035SLZ is appropriate for applications where ±20% capacitance tolerance is acceptable and standard inventory levels are sufficient. The TAP155K035SCS provides tighter ±10% tolerance specification while maintaining identical electrical and mechanical characteristics, with higher inventory availability (1809 units versus 934 units). Both components are suitable for direct substitution in through-hole radial mounting applications requiring 1.5 µF at 35 V operation.

Frequently Asked Questions (FAQ)

Q: Can TAP155K035SCS replace TAP155M035SLZ in existing designs?

A: Yes. Both parts share identical capacitance (1.5 µF), voltage rating (35 V), ESR (6 Ohm), temperature performance, and physical dimensions. The substitute offers improved tolerance (±10% versus ±20%). No circuit modifications or PCB layout changes are required.

Q: What is the difference between these two parts?

A: The primary difference is capacitance tolerance. TAP155M035SLZ specifies ±20% tolerance, while TAP155K035SCS specifies ±10% tolerance. All other electrical and mechanical parameters are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the same radial through-hole package with 0.177" diameter (4.50mm), 0.276" maximum seated height (7.00mm), and 0.098" lead spacing (2.50mm).

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP155M035SLZ and TAP155K035SCS are ROHS3 compliant and REACH unaffected.

Q: Which part should be selected for new designs?

A: Selection depends on tolerance requirements. For applications requiring tighter capacitance tolerance control, TAP155K035SCS is the appropriate choice. For applications where ±20% tolerance is acceptable, either part is suitable based on availability and cost considerations.
