K682J20C0GF53L2 Equivalent & Substitute Parts

Part Overview

The K682J20C0GF53L2 is a 6800 pF ceramic capacitor manufactured by Vishay Beyschlag/Draloric/BC Components in the Mono-Kap™ K series. This radial through-hole capacitor operates at 50V with C0G/NP0 temperature coefficient and ±5% tolerance, suitable for general-purpose applications across the -55°C to 125°C temperature range. The part is currently active in production. Equivalent substitutes are necessary when the original part becomes unavailable or when design revisions require alternative sourcing from different manufacturers while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the K682J20C0GF53L2 is determined by strict equivalence across the following critical parameters: capacitance value (6800 pF), tolerance (±5%), rated voltage (50V), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), mounting type (through-hole radial), and RoHS3 compliance. All substitute parts must maintain identical electrical performance and physical compatibility with the original design. Lead spacing and package dimensions are secondary considerations that may vary within acceptable mechanical tolerances for PCB layout accommodation.

Parameter Comparison

Engineering Selection Recommendations

All three TDK substitute parts (FK18C0G1H682JN020, FK24C0G1H682JN000, FK28C0G1H682JN000) meet the core electrical requirements and maintain ROHS3 compliance equivalent to the K682J20C0GF53L2. However, the original Vishay part maintains active product status, while all TDK alternatives are designated "Not For New Designs," indicating these parts are in mature or end-of-life phases.

For new designs, the K682J20C0GF53L2 remains the preferred selection due to its active status and continued manufacturer support. For legacy system maintenance or when the Vishay part becomes unavailable, the TDK FK series substitutes provide electrical equivalence with consideration for mechanical package variations. Lead spacing differences (2.50mm versus 5.00mm) require PCB layout verification before implementation.

Frequently Asked Questions (FAQ)

Q: Can FK18C0G1H682JN020 replace K682J20C0GF53L2 directly on the PCB?

A: Electrical substitution is valid. However, FK18C0G1H682JN020 maintains the same 2.50mm lead spacing as the original part, making it mechanically compatible. Verify PCB hole positioning and clearances before soldering.

Q: What is the difference between FK24C0G1H682JN000 and FK28C0G1H682JN000?

A: Both parts are electrically identical (6800 pF, 50V, C0G/NP0). The primary difference is physical dimension: FK24C0G1H682JN000 measures 5.50mm x 4.50mm with 5.00mm lead spacing, while FK28C0G1H682JN000 measures 4.00mm x 2.50mm with 5.00mm lead spacing. Lead spacing differences require PCB layout accommodation.

Q: Why are the TDK parts marked "Not For New Designs"?

A: This designation indicates the parts are in mature production phases with limited future availability. For new product development, source the active K682J20C0GF53L2 or contact manufacturers for current-generation alternatives.

Q: Are all substitutes RoHS3 compliant?

A: Yes. The K682J20C0GF53L2 and all three TDK substitutes (FK18C0G1H682JN020, FK24C0G1H682JN000, FK28C0G1H682JN000) are ROHS3 compliant.

Q: Can I use FK24C0G1H682JN000 in a design originally specified for K682J20C0GF53L2?

A: Electrical substitution is valid. However, FK24C0G1H682JN000 has 5.00mm lead spacing compared to the original 2.50mm spacing, requiring PCB redesign. Verify mechanical fit and clearances before implementation.
