1808WC101MATME Equivalent & Substitute Parts

Part Overview

The 1808WC101MATME is a 100 pF ceramic capacitor rated for 2500V (2.5kV) with X7R temperature coefficient, manufactured by KYOCERA AVX. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part is currently active and available in stock with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when component availability is limited, lead times are extended, or design requirements necessitate alternative electrical or mechanical characteristics within acceptable parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1808WC101MATME is determined by the following critical parameters:

• Capacitance Value: Must be 100 pF
• Package / Case: Must be 1808 (4520 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Voltage Rating: Must be equal to or greater than 2500V
• Temperature Coefficient: X7R or C0G/NP0 acceptable (both provide stable performance across operating range)
• Operating Temperature Range: Must support -55°C to 125°C
• Compliance: RoHS3 and REACH status must be maintained

The identified substitute parts meet or exceed these parameters while maintaining compatibility with the original design specifications.

Parameter Comparison

Engineering Selection Recommendations

C1808C101KHRAC7800 (KEMET) provides direct substitution with improved tolerance (±10% versus ±20%) and higher voltage rating (3000V versus 2500V). The X7R temperature coefficient maintains identical thermal performance. This part is available in Tape & Reel packaging and carries ROHS3 compliance with unlimited MSL rating.

C4520C0G3F101K200KA (TDK) offers substitution with C0G/NP0 temperature coefficient, which provides superior stability and lower temperature coefficient drift compared to X7R. The 3000V rating exceeds the original specification. This part is available in Cut Tape and Digi-Reel packaging with ROHS3 compliance and unlimited MSL rating. The increased thickness (2.20mm maximum) must be verified against PCB assembly constraints.

Both substitute parts maintain full compliance with RoHS3 and REACH requirements and support the complete operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can C1808C101KHRAC7800 be used as a direct replacement for 1808WC101MATME?

A: Yes. Both parts share identical capacitance (100 pF), package (1808/4520 Metric), temperature coefficient (X7R), and operating temperature range. The KEMET part offers improved tolerance (±10%) and higher voltage rating (3000V), making it electrically compatible and mechanically interchangeable.

Q: What is the difference between X7R and C0G temperature coefficients?

A: X7R provides ±15% capacitance change across the -55°C to 125°C operating range. C0G/NP0 provides superior stability with minimal capacitance drift across temperature. Both are acceptable for this application; C0G selection depends on circuit requirements for tighter capacitance tolerance over temperature.

Q: Are there dimensional differences that affect PCB layout?

A: Yes. The TDK C4520C0G3F101K200KA has a maximum thickness of 2.20mm, compared to 1.80mm for the original part and 1.75mm for the KEMET substitute. Length and width dimensions vary slightly (within 0.008" tolerance). Verify PCB assembly clearances before selection.

Q: Do all substitute parts meet compliance requirements?

A: Yes. All listed parts are ROHS3 compliant, REACH unaffected, and carry unlimited moisture sensitivity level (MSL 1), matching the original part's compliance profile.

Q: What packaging options are available for each substitute?

A: The KEMET C1808C101KHRAC7800 is supplied in Tape & Reel (TR) packaging. The TDK C4520C0G3F101K200KA is supplied in Cut Tape (CT) and Digi-Reel packaging. Packaging selection depends on assembly process requirements and volume.
