06123C104MAT2S Ceramic Capacitor Equivalent & Substitute Parts

Part Overview

The 06123C104MAT2S is a 0.1 µF ceramic capacitor manufactured by KYOCERA AVX, rated for 25V with X7R temperature coefficient and 0612 (1632 Metric) package configuration. This component is designed for bypass and decoupling applications in surface mount assemblies. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified based on matching capacitance, package geometry, and dielectric characteristics while allowing for controlled variations in voltage rating and tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 06123C104MAT2S is determined by the following criteria:

Primary Matching Parameters (Non-Negotiable):

• Capacitance: 0.1 µF (exact match required)
• Package / Case: 0612 (1632 Metric) (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

Allowable Variation Parameters:

• Voltage Rating: May be equal to or higher than 25V
• Tolerance: May be tighter (±10%) or equal (±20%)
• Manufacturer: Different manufacturers permitted if all primary parameters match

Compliance Requirements:

• RoHS3 Compliant (mandatory)
• Moisture Sensitivity Level 1 (mandatory)

All substitute parts listed meet these criteria and are suitable for direct replacement in applications where the original 06123C104MAT2S is specified.

Parameter Comparison

Engineering Selection Recommendations

06123C104KAT2A (KYOCERA AVX Upgrade): This substitute offers improved tolerance specification (±10% versus ±20%) while maintaining identical voltage rating, package, and thermal characteristics. Thickness increases from 0.030" to 0.037", which remains within typical PCB assembly constraints. Selection is appropriate for applications requiring tighter capacitance tolerance without voltage derating.

06125C104MAT2A (KYOCERA AVX MFR Recommended): This part provides voltage derating from 25V to 50V, maintaining the same manufacturer and tolerance specification. Thickness increases to 0.050", which may require PCB layout verification in space-constrained designs. This option is suitable for applications where higher voltage margin is required or where component availability of the original specification is limited.

CL0612KRX7R9BB104 (YAGEO Upgrade): This cross-manufacturer substitute combines voltage derating (50V) with improved tolerance (±10%). Thickness specification of 0.037" is comparable to the KYOCERA AVX upgrade option. Selection is appropriate when multi-source qualification is required or when YAGEO components are preferred within the supply chain.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can I use a 50V rated capacitor in place of the 25V rated 06123C104MAT2S?

A: Yes. Higher voltage ratings provide additional safety margin and are electrically compatible in circuits designed for lower voltage operation. The 50V-rated substitutes (06125C104MAT2A and CL0612KRX7R9BB104) are direct functional replacements.

Q: What is the significance of tolerance differences between ±20% and ±10%?

A: Tolerance defines the allowable deviation from the nominal 0.1 µF capacitance value. The ±10% tolerance parts (06123C104KAT2A and CL0612KRX7R9BB104) provide tighter capacitance accuracy, which may be required in precision filtering or timing circuits. The ±20% tolerance parts are suitable for general bypass and decoupling applications where capacitance variation has minimal impact on circuit performance.

Q: Are there physical size differences between these parts?

A: All parts share identical length and width (0.063" x 0.126"), maintaining PCB footprint compatibility. Thickness varies: the main part measures 0.030", while substitutes range from 0.037" to 0.050". Verify PCB assembly clearance specifications before selecting parts with increased thickness.

Q: Can I mix manufacturers in the same assembly?

A: Yes. The KYOCERA AVX and YAGEO parts listed are all qualified substitutes meeting identical electrical and mechanical specifications. Multi-source qualification is standard practice in component selection.

Q: What does X7R temperature coefficient mean?

A: X7R indicates a ceramic dielectric material with capacitance variation of ±15% across the operating temperature range of -55°C to 125°C. This specification is consistent across all listed parts and ensures stable performance across the full temperature range.

Q: Are all these parts RoHS3 compliant?

A: Yes. All listed parts carry ROHS3 Compliant certification and MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and manufacturing standards.
