Substitute Part Grouping Explanation

Substitution eligibility for the C1005CH1H030B050BA is determined by strict alignment of the following electrical and mechanical parameters:

• Capacitance value: 3 pF (exact match required)
• Tolerance: ±0.1pF (exact match required)
• Voltage rating: 50V (minimum requirement; higher ratings acceptable)
• Package / Case: 0402 (1005 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Physical dimensions: 0.039" L x 0.020" W, 0.022" max thickness (exact match required)
• RoHS and MSL compliance: ROHS3 Compliant, MSL 1 (minimum requirements)

Temperature coefficient variations (CH vs. C0G/NP0) represent functional differences in temperature stability characteristics. Substitutes with C0G/NP0 coefficients provide superior temperature stability across a wider operating range (-55°C ~ 125°C vs. -25°C ~ 85°C) and are acceptable for applications where the original CH specification is not mandated by circuit design constraints.

Parameter Comparison

Engineering Selection Recommendations

Selection among available substitutes depends on product lifecycle status and compliance requirements:

C1005C0G1H030B050BA (TDK, MFR Recommended): This part maintains TDK manufacturer continuity while upgrading the temperature coefficient from CH to C0G/NP0. The extended operating temperature range (-55°C ~ 125°C) provides enhanced thermal stability. Product status is Not For New Designs, indicating limited future availability. Suitable for legacy system maintenance where TDK sourcing is preferred.

GRM1555C1H3R0BA01D (Murata, Direct Substitute): Murata-manufactured equivalent with identical electrical specifications and C0G/NP0 temperature coefficient. Cut Tape and Digi-Reel packaging options support both production and component-level sourcing. Product status is Not For New Designs. Appropriate for applications requiring Murata supply chain integration.

C0402C309B5GAC7867 (KEMET, Upgrade): KEMET-manufactured part with Active product status, ensuring long-term availability and production support. Maintains all electrical and mechanical specifications with C0G/NP0 temperature coefficient. This part is the recommended choice for new designs and ongoing production requiring assured component supply.

All three substitutes meet ROHS3 compliance and MSL 1 requirements, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can I substitute the C1005CH1H030B050BA with a C0G/NP0 temperature coefficient part?

A: Yes. The substitute parts listed feature C0G/NP0 temperature coefficients, which provide superior temperature stability across a wider operating range (-55°C ~ 125°C vs. -25°C ~ 85°C). This substitution is acceptable unless the circuit design explicitly requires the CH temperature coefficient specification.

Q: Are all substitute parts available in the same 0402 package?

A: Yes. All substitute parts are manufactured in the 0402 (1005 Metric) package with identical physical dimensions (0.039" L x 0.020" W, 0.022" max thickness), ensuring direct PCB footprint compatibility.

Q: What is the difference between the three substitute options?

A: The primary differences are manufacturer identity and product lifecycle status. C1005C0G1H030B050BA and GRM1555C1H3R0BA01D are Not For New Designs, indicating limited future availability. C0402C309B5GAC7867 has Active status, providing assured long-term supply and production support. Selection depends on supply chain preference and design lifecycle requirements.

Q: Do all parts meet RoHS and MSL requirements?

A: Yes. All parts listed are ROHS3 Compliant with MSL 1 (Unlimited) rating, meeting standard environmental and moisture sensitivity requirements for surface mount assembly.

Q: Can I use a higher voltage-rated capacitor as a substitute?

A: The specified 50V rating is the minimum requirement. Higher voltage ratings are electrically acceptable and do not affect circuit function. However, all listed substitutes are rated at 50V, matching the original specification.

Q: What packaging formats are available for these substitutes?

A: C1005C0G1H030B050BA and C0402C309B5GAC7867 are supplied in Tape & Reel (TR) format. GRM1555C1H3R0BA01D is available in Cut Tape (CT) and Digi-Reel format, providing flexibility for different procurement and assembly workflows.
