Equivalent & Substitute Parts for 1206J0630682JCT

Part Overview

The 1206J0630682JCT is a 6800 pF ceramic capacitor manufactured by Knowles Syfer, rated at 63V with C0G/NP0 temperature coefficient and ±5% tolerance. This component is designed for general-purpose applications requiring stable capacitance across temperature ranges from -55°C to 125°C.

Substitute Part Grouping Explanation

Substitution logic for the 1206J0630682JCT is based on the following allowed parameters:

Electrical Compatibility Requirements:

Capacitance value must remain 6800 pF
Tolerance must be ±5%
Voltage rating must be equal to or greater than 63V
Temperature coefficient must be C0G/NP0 or X7R (both acceptable for general-purpose applications)
Operating temperature range must cover -55°C minimum to 125°C minimum

Mechanical & Package Compatibility Requirements:

Package / Case must be 1206 (3216 Metric)
Mounting type must be Surface Mount, MLCC
Physical dimensions must be 0.126" L x 0.063" W (3.20mm x 1.60mm)

Compliance Requirements:

RoHS3 Compliant
MSL Level 1 (Unlimited)

Substitute parts are grouped into two categories: Upgrade substitutes (higher voltage rating with C0G/NP0 coefficient) and Manufacturer-recommended substitutes (higher voltage rating with X7R coefficient for bypass and decoupling applications).

Engineering Selection Recommendations

All substitute parts listed maintain active product status and full RoHS3 compliance with MSL Level 1 rating, ensuring regulatory and environmental compatibility with the original 1206J0630682JCT.

C0G/NP0 Temperature Coefficient Substitutes (Electrical Equivalence):

C1206C682J1GAC7800 (KEMET) and C3216NP02A682J115AA (TDK Corporation) maintain the same C0G/NP0 temperature coefficient as the original part, providing identical capacitance stability across temperature. Both are rated at 100V, exceeding the original 63V specification. C3216NP02A682J115AA extends the upper operating temperature to 150°C.

X7R Temperature Coefficient Substitutes (Application-Specific):

C1206C682J1RAC7800 (KEMET) and KGM31BR72A682JT (KYOCERA AVX) employ X7R temperature coefficient, suitable for bypass and decoupling applications. Both are rated at 100V and maintain the -55°C to 125°C operating range. These parts offer lower ESL characteristics in specific applications.

All substitute parts are packaged in 1206 (3216 Metric) format with Surface Mount, MLCC mounting type, ensuring direct mechanical and electrical compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can C1206C682J1GAC7800 directly replace 1206J0630682JCT? A: Yes. Both parts share identical capacitance (6800 pF), tolerance (±5%), temperature coefficient (C0G/NP0), and operating temperature range (-55°C to 125°C). The KEMET part is rated at 100V, which exceeds the original 63V specification, making it electrically compatible. Package and mounting type are identical (1206, Surface Mount, MLCC).

Q: What is the difference between C0G/NP0 and X7R temperature coefficients? A: C0G/NP0 provides stable capacitance across temperature with minimal variation, suitable for precision applications. X7R allows greater capacitance variation across temperature but is acceptable for bypass and decoupling functions. The original 1206J0630682JCT uses C0G/NP0; X7R substitutes (C1206C682J1RAC7800, KGM31BR72A682JT) are recommended only for applications tolerant of capacitance drift.

Q: Does the thickness difference between substitute parts affect PCB assembly? A: All substitute parts maintain the 1206 (3216 Metric) package specification. Thickness variations (0.035" to 0.063") are within standard MLCC tolerances and do not affect PCB footprint compatibility or reflow soldering processes.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts carry RoHS3 compliance certification and MSL Level 1 (Unlimited) rating, matching the original part's environmental and regulatory status.

Q: Which substitute offers the widest operating temperature range? A: C3216NP02A682J115AA (TDK Corporation) extends the upper operating temperature to 150°C, compared to 125°C for the original part and other substitutes, while maintaining the -55°C lower limit.
