Substitute Part Grouping Explanation

Substitution for the 1808GC680MATME is determined by the following critical parameters:

• Capacitance Value: 68 pF (exact match required)
• Package / Case: 1808 (4520 Metric) (exact match required for mechanical compatibility)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Voltage Rating: Minimum 2000V (equal or higher voltage rating is acceptable)
• Temperature Coefficient: X7R or equivalent (C0G/NP0 acceptable as superior stability alternative)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity: MSL 1 (unlimited handling)

The identified substitute part C4520C0G3F680K200KA from TDK Corporation meets all substitution criteria with enhanced specifications in voltage rating and temperature coefficient stability.

Parameter Comparison

Engineering Selection Recommendations

The C4520C0G3F680K200KA substitute part from TDK Corporation is qualified for direct replacement in applications using the 1808GC680MATME. Both components are active production parts with ROHS3 compliance and identical moisture sensitivity ratings. The substitute provides enhanced electrical performance through higher voltage rating (3000V vs. 2000V) and improved temperature coefficient stability (C0G/NP0 vs. X7R), with tighter capacitance tolerance (±10% vs. ±20%). Physical dimensions are compatible within the 1808 (4520 Metric) package specification, with minor variations in length and thickness that remain within standard PCB assembly tolerances. Both parts are suitable for general-purpose high-voltage applications across the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the C4520C0G3F680K200KA be used as a direct replacement for the 1808GC680MATME?

A: Yes. Both parts share identical capacitance (68 pF), package type (1808/4520 Metric), mounting method (Surface Mount MLCC), and operating temperature range (-55°C ~ 125°C). The substitute meets or exceeds all electrical and mechanical requirements.

Q: What are the key differences between these two parts?

A: The substitute part offers three improvements: higher voltage rating (3000V vs. 2000V), tighter capacitance tolerance (±10% vs. ±20%), and superior temperature coefficient stability (C0G/NP0 vs. X7R). Physical dimensions vary slightly within acceptable tolerances.

Q: Are there any PCB layout considerations when substituting these parts?

A: The substitute part has a maximum thickness of 0.087" (2.20mm) compared to 0.071" (1.80mm) for the original part. Verify clearance in your PCB assembly design. Length and width dimensions are compatible within standard 1808 package specifications.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the 1808GC680MATME and C4520C0G3F680K200KA are rated MSL 1 (Unlimited), requiring no special moisture handling or baking procedures.

Q: Are both parts RoHS compliant?

A: Yes. Both components are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: Which part should I select for new designs?

A: Selection depends on application requirements. The substitute part (C4520C0G3F680K200KA) is recommended for designs requiring higher voltage margin or improved temperature stability. The original part (1808GC680MATME) is suitable for applications with established 2000V voltage specifications and standard tolerance requirements.
