K181J10C0GF5TL2 Equivalent & Substitute Parts

Part Overview

The K181J10C0GF5TL2 is a 180 pF ±5% 50V ceramic capacitor with C0G/NP0 temperature coefficient manufactured by Vishay Beyschlag/Draloric/BC Components. This radial through-hole component is part of the Mono-Kap™ K series and maintains active product status. Equivalent and substitute parts are necessary when the original packaging format (Tape & Reel) is unavailable, when alternative lead spacing configurations are required, or when sourcing from different manufacturers becomes advantageous for supply chain continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the K181J10C0GF5TL2 is determined by the following criteria:

Capacitance value: 180 pF (exact match required)
Tolerance: ±5% (exact match required)
Voltage rating: 50V (exact match required)
Temperature coefficient: C0G or NP0 (functionally equivalent)
Mounting type: Through Hole (exact match required)
Package case: Radial (exact match required)
Operating temperature range: -55°C ~ 125°C (exact match required)
RoHS compliance: ROHS3 Compliant (required for regulatory alignment)

Physical dimensions and lead spacing may vary within acceptable tolerances for PCB layout compatibility. Packaging format (Tape & Reel, Cut Tape, or Bulk) does not affect electrical equivalence but impacts procurement and assembly processes.

Engineering Selection Recommendations

K181J15C0GF5TL2 is the primary direct substitute, maintaining identical electrical specifications and lead spacing while differing only in packaging format (Cut Tape versus Tape & Reel). Both parts are manufactured by Vishay and carry Active product status.

RDE5C1H181J0P1H03B (Murata Electronics) and SR155A181JAR (KYOCERA AVX) are functionally equivalent alternatives with Active product status. Both meet ROHS3 compliance and maintain the required electrical parameters. Minor dimensional variations exist but do not affect PCB compatibility for standard through-hole applications.

FK18C0G1H181JN020 and FK28C0G1H181JN000 (TDK Corporation) carry "Not For New Designs" status and should be used only for legacy system maintenance or repair applications where original component sourcing is critical.

Frequently Asked Questions (FAQ)

Q: Can K181J15C0GF5TL2 replace K181J10C0GF5TL2 directly?

A: Yes. Both parts are electrically identical with matching capacitance, tolerance, voltage rating, temperature coefficient, and lead spacing. The difference is packaging format: K181J15C0GF5TL2 is supplied in Cut Tape while K181J10C0GF5TL2 is supplied in Tape & Reel. PCB assembly compatibility is identical.

Q: What is the difference between C0G and NP0 temperature coefficients?

A: C0G and NP0 designations are functionally equivalent. Both indicate zero temperature coefficient ceramic capacitors with identical performance characteristics across the -55°C ~ 125°C operating range.

Q: Can I use SR155A181JAR as a substitute if lead spacing differs slightly?

A: SR155A181JAR has 0.100" (2.54mm) lead spacing versus the standard 0.098" (2.50mm). This 0.002" difference is within typical PCB tolerance for through-hole mounting and is compatible with standard 0.1" grid layouts. Verify PCB pad spacing before selection.

Q: Why are FK18C0G1H181JN020 and FK28C0G1H181JN000 marked "Not For New Designs"?

A: These TDK parts carry legacy status, indicating they are available for existing applications but not recommended for new product development. Active alternatives from Murata and KYOCERA AVX are preferred for new designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the regulatory requirements of the original K181J10C0GF5TL2.
