TAP155M035SCS Equivalent & Substitute Parts

Part Overview

The TAP155M035SCS is a 1.5 µF conformal coated tantalum capacitor rated for 35 V operation in a radial through-hole package. This component is classified as Active product status and is suitable for general-purpose applications requiring reliable energy storage in compact form factors. Substitute parts may be required due to inventory constraints, design optimization for tighter tolerances, or application-specific performance requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the TAP155M035SCS is determined by the following critical parameters:

• Capacitance Value: Must be 1.5 µF (exact match required)
• Voltage Rating: Must be 35 V or higher (equal or superior rating acceptable)
• Package Type: Must be Radial Through Hole (mechanical and electrical compatibility)
• Conformal Coating: Must maintain conformal coated specification
• ESR: Must be 6 Ohm (electrical performance requirement)
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Tolerance: May vary within acceptable design margins

The TAP155K035SCS qualifies as a direct substitute based on matching all critical parameters while offering improved tolerance specification (±10% versus ±20%).

Parameter Comparison

Engineering Selection Recommendations

Both TAP155M035SCS and TAP155K035SCS are Active product status components manufactured by KYOCERA AVX and maintain full compliance with ROHS3 and REACH requirements. The primary distinction between these parts is tolerance specification: the substitute TAP155K035SCS provides ±10% tolerance compared to the ±20% tolerance of the main part. All other electrical, mechanical, and environmental parameters remain identical.

Selection between these parts should be based on circuit design tolerance requirements. Applications requiring tighter capacitance accuracy benefit from the TAP155K035SCS specification. Both parts are suitable for deployment in equivalent circuit positions without modification to PCB layout or electrical design.

Frequently Asked Questions (FAQ)

Q: Can TAP155K035SCS replace TAP155M035SCS in existing designs?

A: Yes. The TAP155K035SCS is a direct mechanical and electrical substitute. Identical package dimensions, lead spacing, voltage rating, and ESR ensure compatibility without PCB redesign. The improved tolerance specification of the substitute part does not create incompatibility.

Q: What is the primary difference between these two parts?

A: The tolerance specification differs. TAP155M035SCS carries ±20% tolerance, while TAP155K035SCS carries ±10% tolerance. All other parameters—capacitance value, voltage rating, package type, ESR, and operating temperature range—are identical.

Q: Are both parts suitable for conformal coating applications?

A: Yes. Both TAP155M035SCS and TAP155K035SCS are specified as conformal coated tantalum capacitors and maintain this coating specification.

Q: Do these parts require different PCB footprints?

A: No. Both parts share identical physical dimensions: 0.177" diameter (4.50mm), 0.276" maximum seated height (7.00mm), and 0.098" lead spacing (2.50mm). PCB footprints are interchangeable.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component deployment.
