Equivalent & Substitute Parts for 2220J1000682JCT

Part Overview

The 2220J1000682JCT is a 6800 pF ceramic capacitor manufactured by Knowles Syfer, rated at 100V with C0G/NP0 temperature coefficient. This surface mount multilayer ceramic capacitor (MLCC) is designed for general purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained within the same package footprint.

Substitute Part Grouping Explanation

Substitution for the 2220J1000682JCT is determined by the following criteria:

• Capacitance value must be 6800 pF
• Tolerance must be ±5% or tighter
• Temperature coefficient must be C0G or NP0
• Package must be 2220 (5750 Metric)
• Mounting type must be Surface Mount, MLCC
• Operating temperature range must cover -55°C to 125°C
• RoHS3 compliance required
• MSL rating must be 1 (Unlimited)

The voltage rating may exceed the original specification, as higher voltage ratings provide backward compatibility in applications where the original 100V rating is sufficient. The substitute part C2220C682JCGAC7800 meets all mandatory criteria while offering enhanced voltage capability at 500V.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The C2220C682JCGAC7800 substitute provides identical electrical performance with a higher voltage rating of 500V, enabling use in applications requiring greater voltage margin. The reduced thickness of the substitute part (1.80mm versus 2.50mm) may provide design flexibility in space-constrained layouts while maintaining the same footprint dimensions. Selection between the original and substitute should be based on application voltage requirements and available board space.

Frequently Asked Questions (FAQ)

Q: Can the C2220C682JCGAC7800 be used as a direct replacement for the 2220J1000682JCT?

A: Yes. Both parts share identical capacitance (6800 pF), tolerance (±5%), temperature coefficient (C0G/NP0), operating temperature range (-55°C to 125°C), and package footprint (2220 / 5750 Metric). The substitute operates at 500V versus the original 100V, providing backward compatibility for applications rated at or below 100V.

Q: What are the mechanical compatibility considerations?

A: Both parts use the same 2220 (5750 Metric) package with identical length and width dimensions (5.70mm x 5.00mm). The substitute has a reduced maximum thickness of 1.80mm compared to 2.50mm for the original, which may affect board assembly clearances in designs with tight vertical constraints.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. Regulatory and environmental compliance is equivalent.

Q: Why would the higher voltage rating of the substitute be beneficial?

A: The 500V rating of the C2220C682JCGAC7800 provides additional voltage margin in applications where transient overvoltage or design margin is a consideration, while maintaining full compatibility with circuits designed for 100V operation.
