TAP156K020GSB Equivalent & Substitute Parts

Part Overview

The TAP156K020GSB is a 15 µF conformal coated tantalum capacitor rated for 20 V operation in a radial through-hole package. Manufactured by KYOCERA AVX, 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 become necessary when the primary part number experiences supply constraints, extended lead times, or when design flexibility permits alternative configurations within the same electrical and mechanical specifications. The TAP156K020GSB has one manufacturer-recommended substitute that maintains functional equivalence across critical parameters.

Substitute Part Grouping Explanation

The TAP156K020GSB has one manufacturer-recommended substitute: TAP156K020CCS. This substitution is valid based on the following criteria:

Electrical Parameters (Must Match):

• Capacitance: 15 µF (identical)
• Voltage Rating: 20 V (identical)
• Tolerance: ±10% (identical)
• ESR: 2.3 Ohm (identical)
• Operating Temperature Range: -55°C to 125°C (identical)
• Lifetime @ Temperature: 1000 Hrs @ 85°C (identical)

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole (identical)
• Package / Case: Radial (identical)
• Diameter: 0.236" (6.00mm) (identical)
• Height - Seated (Max): 0.453" (11.50mm) (identical)

Compliance & Certifications (Must Match):

• RoHS Status: ROHS3 Compliant (identical)
• REACH Status: REACH Unaffected (identical)

Variable Parameter:

• Lead Spacing: TAP156K020GSB uses 0.125" (3.18mm); TAP156K020CCS uses 0.197" (5.00mm)

The lead spacing difference is the only distinguishing factor. Both parts are electrically and mechanically equivalent for applications where the increased lead spacing of the substitute does not create PCB layout conflicts.

Parameter Comparison

Engineering Selection Recommendations

Both TAP156K020GSB and TAP156K020CCS are Active product status components manufactured by KYOCERA AVX and maintain full ROHS3 compliance and REACH unaffected status. Selection between these parts depends solely on PCB layout requirements:

Select TAP156K020GSB when:

• PCB design specifies 0.125" (3.18mm) lead spacing
• Compact board layout requires minimal lead separation

Select TAP156K020CCS when:

• PCB design specifies 0.197" (5.00mm) lead spacing
• Standard through-hole spacing accommodates wider lead separation
• Supply availability favors the substitute part number

Both parts deliver identical electrical performance, thermal characteristics, and regulatory compliance. The choice is determined by mechanical fit within the printed circuit board layout.

Frequently Asked Questions (FAQ)

Q: Can TAP156K020CCS be used as a direct replacement for TAP156K020GSB?

A: TAP156K020CCS is electrically and thermally equivalent to TAP156K020GSB. The only difference is lead spacing: 0.197" (5.00mm) versus 0.125" (3.18mm). Direct substitution is possible only if the PCB layout accommodates the wider lead spacing. Verify hole spacing on the target PCB before substitution.

Q: What does "Conformal Coated" mean for these tantalum capacitors?

A: Conformal coating is a protective layer applied to the capacitor body to enhance moisture resistance and environmental protection. Both the TAP156K020GSB and TAP156K020CCS feature this coating, making them suitable for applications requiring enhanced reliability in humid or corrosive environments.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both parts operate across the -55°C to 125°C temperature range and maintain a rated lifetime of 1000 hours at 85°C. They are suitable for industrial and automotive applications within these thermal specifications.

Q: What is the significance of the 2.3 Ohm ESR specification?

A: ESR (Equivalent Series Resistance) of 2.3 Ohm indicates the internal resistance of the capacitor. This low ESR value is characteristic of tantalum capacitors and ensures efficient energy storage and minimal heat generation during operation. Both parts share this specification.

Q: Do both parts meet RoHS and REACH compliance requirements?

A: Yes. Both TAP156K020GSB and TAP156K020CCS are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: What is the difference between the TAP series designations (GSB vs. CCS)?

A: The suffix designations (GSB and CCS) indicate different internal construction or packaging variants within the TAP series. Both maintain identical electrical and thermal performance for the 15 µF, 20 V specification. The lead spacing difference is the primary distinguishing factor for PCB compatibility.
