TAP155M025SCS Equivalent & Substitute Parts

Part Overview

The TAP155M025SCS is a 1.5 µF conformal coated tantalum capacitor rated for 25 V operation in a radial through-hole package. This component is manufactured by KYOCERA AVX and maintains Active product status with full ROHS3 compliance. Substitute parts are identified when design requirements permit tolerance relaxation, voltage rating upgrades, or when primary inventory availability requires alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the TAP155M025SCS is determined by the following criteria:

Capacitance: Must remain 1.5 µF (no variation permitted)

Mounting Type & Package: Must remain radial through-hole with identical physical dimensions (0.177" Dia, 0.276" Max Height, 0.098" Lead Spacing, Size Code A)

Type & Coating: Must remain conformal coated tantalum

Operating Temperature & Lifetime: Must maintain -55°C to 125°C range and 1000 Hrs @ 85°C minimum

Tolerance: May be relaxed from ±20% to ±10% (tighter tolerance is acceptable)

Voltage Rating: May be upgraded from 25 V to higher ratings (35 V acceptable)

ESR: May vary within acceptable limits for the same capacitance and package

Two substitute parts meet these criteria: TAP155K025SCS (same voltage, improved tolerance) and TAP155K035SCS (higher voltage rating, improved tolerance).

Parameter Comparison

Engineering Selection Recommendations

TAP155K025SCS provides direct electrical equivalence with improved tolerance specification (±10% vs ±20%). All mechanical, thermal, and compliance parameters remain identical. This substitute is suitable for applications where tighter capacitance tolerance is beneficial without requiring voltage rating modification.

TAP155K035SCS maintains identical mechanical fit and thermal characteristics while providing elevated voltage rating (35 V vs 25 V) and improved tolerance (±10%). The ESR is reduced to 6 Ohm. This substitute is suitable for applications operating at or below 25 V where higher voltage margin or lower ESR performance is advantageous.

All three parts maintain Active product status, ROHS3 compliance, and REACH unaffected designation. Selection between these options depends on circuit voltage requirements and tolerance specifications rather than compliance or reliability factors.

Frequently Asked Questions (FAQ)

Q: Can TAP155K025SCS replace TAP155M025SCS in any application?

A: Yes. TAP155K025SCS is electrically and mechanically compatible. The ±10% tolerance is tighter than the original ±20%, making it suitable for all applications designed for TAP155M025SCS.

Q: What is the primary difference between TAP155K025SCS and TAP155K035SCS?

A: TAP155K025SCS maintains 25 V rating with 8 Ohm ESR. TAP155K035SCS provides 35 V rating with 6 Ohm ESR. Both share identical physical dimensions and ±10% tolerance. Selection depends on circuit voltage requirements and ESR performance needs.

Q: Are all three parts physically interchangeable on the PCB?

A: Yes. All three parts share identical radial package dimensions (0.177" Dia, 0.276" Max Height, 0.098" Lead Spacing, Size Code A) and are directly interchangeable at the board level.

Q: Do substitute parts maintain the same operating temperature range?

A: Yes. All three parts operate across -55°C to 125°C with 1000 Hrs @ 85°C lifetime rating.

Q: Are there compliance or certification differences between these parts?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and maintain Active product status with identical regulatory designations (ECCN: EAR99, HTSUS: 8532.21.0040).
