TAP156K035SCS Equivalent & Substitute Parts

Part Overview

The TAP156K035SCS is a 15 µF conformal coated tantalum capacitor rated at 35 V with ±10% tolerance, manufactured by KYOCERA AVX in the TAP series. This radial through-hole component operates across -55°C to 125°C with an ESR of 1.6Ohm and is ROHS3 compliant. The part is currently active in production with 1021 units in stock. Substitute parts are identified when equivalent capacitance and voltage ratings are maintained while allowing variations in tolerance, package size, or ESR characteristics within acceptable engineering parameters.

Substitute Part Grouping Explanation

Substitute parts for the TAP156K035SCS are identified based on the following criteria:

Primary Substitution Parameters:

Capacitance: 15 µF (fixed requirement)
Type: Conformal Coated (fixed requirement)
Mounting Type: Through Hole (fixed requirement)
Package / Case: Radial (fixed requirement)
Series: TAP (fixed requirement)
Operating Temperature: -55°C ~ 125°C (fixed requirement)

Allowable Variations:

Voltage Rating: Lower voltage ratings (6.3 V, 10 V) are acceptable substitutes when the application operates below the rated voltage of the original part
Tolerance: ±20% tolerance is acceptable as an alternative to ±10%
ESR: Variations in ESR are acceptable provided the application does not require the specific 1.6Ohm characteristic
Package Size / Dimensions: Physical size variations are acceptable provided mounting compatibility is maintained

The three identified substitutes maintain the core electrical and mechanical specifications while offering alternatives for different voltage requirements and tolerance specifications.

Engineering Selection Recommendations

All four parts—TAP156K035SCS, TAP156K006SCS, TAP156K010SCS, and TAP156M035SCS—are active products manufactured by KYOCERA AVX with ROHS3 compliance and REACH unaffected status. Selection between these parts depends on application voltage requirements and tolerance specifications:

TAP156K035SCS (Original): Use when 35 V rating and ±10% tolerance are required. Provides 1.6Ohm ESR and standard package dimensions (7.00mm diameter, 10.50mm height).

TAP156K006SCS: Use only in applications operating at 6.3 V or below. Offers ±10% tolerance with higher ESR (5Ohm) and smaller package footprint (5.00mm diameter, 8.50mm height). Suitable for space-constrained designs operating at lower voltages.

TAP156K010SCS: Use in applications operating at 10 V or below. Maintains ±10% tolerance with 3.7Ohm ESR and compact package dimensions (5.00mm diameter, 9.00mm height). Provides intermediate voltage rating between 6.3 V and 35 V options.

TAP156M035SCS: Use when 35 V rating is required with relaxed tolerance specification (±20%). Matches the original part's ESR (1.6Ohm) and package dimensions (7.00mm diameter, 10.50mm height). Suitable for applications where ±20% capacitance tolerance is acceptable.

Frequently Asked Questions (FAQ)

Q: Can TAP156K006SCS or TAP156K010SCS be used as direct replacements for TAP156K035SCS?

A: Only if the application circuit operates at or below the substitute part's voltage rating. TAP156K006SCS is suitable for circuits operating at 6.3 V maximum; TAP156K010SCS for circuits operating at 10 V maximum. Using a lower-rated voltage part in a higher-voltage circuit will result in component failure.

Q: What is the difference between TAP156K035SCS and TAP156M035SCS?

A: Both parts share identical voltage rating (35 V), ESR (1.6Ohm), and package dimensions. The primary difference is tolerance: TAP156K035SCS specifies ±10% while TAP156M035SCS specifies ±20%. Select TAP156M035SCS only when the application circuit can tolerate ±20% capacitance variation.

Q: Are the smaller package options (TAP156K006SCS and TAP156K010SCS) compatible with PCB layouts designed for TAP156K035SCS?

A: Lead spacing (0.098" / 2.50mm) is identical across all parts, ensuring through-hole compatibility. However, the smaller diameter (5.00mm vs 7.00mm) and reduced height may affect mechanical fit depending on PCB layout constraints. Verify physical clearance before substitution.

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

A: Yes. All four parts operate across -55°C to 125°C with 1000 hours lifetime at 85°C, ensuring thermal performance consistency across the substitution group.

Q: Are there any compliance or regulatory differences between these parts?

A: No. All parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code (8532.21.0040).
