Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 04026D683MAT2A are qualified based on the following criteria:

Mandatory Matching Parameters:

• Capacitance: 0.068 µF (exact match required)
• Package / Case: 0402 (1005 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• RoHS Status: ROHS3 Compliant (compliance requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (handling requirement)

Allowable Variations:

• Voltage Rating: Substitutes rated at 10V, 16V, or higher are acceptable as they provide equal or greater voltage margin
• Tolerance: Substitutes with ±10% tolerance are acceptable as they provide tighter specification than the original ±20%
• Temperature Coefficient: X5R or X7R are both acceptable; X7R provides extended operating range (-55°C ~ 125°C vs -55°C ~ 85°C)
• Manufacturer: KYOCERA AVX, KEMET, YAGEO, or Murata Electronics

Substitutes are organized by voltage rating upgrade path, with tolerance and temperature coefficient improvements noted.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

For applications requiring direct replacement with improved specifications, select from KYOCERA AVX, KEMET, or YAGEO parts with Active product status. The 0402ZD683KAT2A (KYOCERA AVX, 10V, ±10%) provides the closest upgrade path with same manufacturer and improved tolerance. The KGM05AR51C683KH (KYOCERA AVX, 16V, ±10%) offers maximum voltage margin within the same manufacturer family.

For multi-source qualification, the C0402C683K8PAC7867 (KEMET, 10V, X5R) and CC0402KRX7R6BB683 (YAGEO, 10V, X7R) provide equivalent 10V ratings with Active status and ±10% tolerance. The C0402C683K4RAC7867 (KEMET, 16V, X7R) and CC0402KRX5R7BB683 (YAGEO, 16V, X5R) support 16V applications with Active status.

Legacy Substitutes (Not For New Designs):

The GRM155R61A683KA01D and GRM155R61C683KA88D (Murata Electronics) are classified as Not For New Designs and should not be selected for new product development. These parts are listed for reference only in legacy system maintenance scenarios.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and 0402 package form factor required for direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher voltage rating than the original 04026D683MAT2A?

A: Yes. Substitute parts rated at 10V or 16V are fully compatible. Higher voltage ratings provide additional safety margin and do not degrade circuit performance in applications designed for 6.3V operation. The capacitance and package dimensions remain identical.

Q: What is the difference between X5R and X7R temperature coefficients?

A: X5R maintains capacitance within ±15% across -55°C to +85°C. X7R maintains capacitance within ±15% across -55°C to +125°C. X7R substitutes provide extended temperature range operation but are otherwise electrically equivalent for standard applications.

Q: Are KEMET C0402C683K8PAC7867 and YAGEO CC0402KRX7R6BB683 interchangeable?

A: Both parts share identical capacitance (0.068 µF), voltage rating (10V), package (0402), and tolerance (±10%). The primary difference is temperature coefficient: C0402C683K8PAC7867 uses X5R (-55°C ~ 85°C) while CC0402KRX7R6BB683 uses X7R (-55°C ~ 125°C). Selection depends on circuit operating temperature requirements.

Q: Why are Murata GRM155R61A683KA01D and GRM155R61C683KA88D marked "Not For New Designs"?

A: These parts are legacy components retained in inventory for existing product support only. New designs should select from Active status alternatives: KYOCERA AVX, KEMET, or YAGEO equivalents with matching specifications.

Q: Can I substitute the ±20% tolerance original part with a ±10% tolerance substitute?

A: Yes. Tighter tolerance (±10%) is a specification improvement and is fully compatible. Circuits designed for ±20% tolerance will operate correctly with ±10% tolerance components.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Most substitutes are available in Tape & Reel (TR) packaging. The KGM05AR51C683KH is supplied in Cut Tape (CT) & Digi-Reel® format. Verify packaging requirements with your procurement specification before final part selection.
