C0603X5R1H331M Equivalent & Substitute Parts

Part Overview

The TDK Corporation C0603X5R1H331M is a 330 pF ceramic capacitor rated at 50V with X5R temperature coefficient, packaged in 0201 (0603 Metric) surface mount form factor. This part is classified as obsolete, necessitating identification of active equivalent and substitute components for ongoing production and design requirements. The 330 pF capacitance value with ±20% tolerance and X5R stability makes this component suitable for general-purpose applications requiring stable capacitance across the -55°C to 85°C operating range.

Substitute Part Grouping Explanation

Substitute parts for the C0603X5R1H331M are categorized based on the following substitution criteria:

Upgrade Substitutes — Parts with improved specifications while maintaining core electrical compatibility:

• Same capacitance value (330 pF)
• Same voltage rating (50V)
• Same package (0201 / 0603 Metric)
• Enhanced temperature coefficient (X7R instead of X5R) providing wider operating temperature range (-55°C to 125°C)
• Tighter tolerance options (±5% or ±10% versus ±20%)
• Active product status with higher inventory availability

Manufacturer Recommended Substitute — Part meeting functional requirements with voltage derating:

• Same capacitance (330 pF)
• Lower voltage rating (25V versus 50V)
• X5R temperature coefficient matching original
• Same package and mounting type
• Suitable for applications not requiring full 50V rating

Parametric Equivalents — Parts with identical electrical and mechanical specifications:

• Same capacitance (330 pF)
• Same voltage rating (50V)
• Same temperature coefficient (X5R)
• Same tolerance (±20%)
• Same package (0201 / 0603 Metric)
• Active product status from alternative manufacturers

Engineering Selection Recommendations

For Direct Replacement with Enhanced Performance: Select YAGEO CC0201JRX7R9BB331 or CC0201KRX7R9BB331, Murata GRM033R71H331KA12D, or Vishay Vitramon VJ0201Y331KXACW1BC. These upgrade substitutes maintain the 50V rating and 0201 package while providing X7R temperature stability across -55°C to 125°C. The X7R coefficient offers superior capacitance stability compared to X5R across extended temperature ranges. All parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating.

For Parametric Equivalence: Select Taiyo Yuden MLASU063SB5331MFNA01 or MSASU063SB5331MFNA01 for identical electrical specifications matching the original C0603X5R1H331M. Both maintain 330 pF capacitance, ±20% tolerance, 50V rating, and X5R temperature coefficient with -55°C to 85°C operating range. These parts are active products suitable for applications requiring exact parameter matching.

For Voltage-Derated Applications: Select KYOCERA AVX KGM03AR51E331KH when circuit design permits 25V operation. This part maintains X5R temperature stability and identical package specifications while offering active product status. Use only in applications where the 50V rating is not required.

All recommended substitutes are ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can I use the YAGEO CC0201JRX7R9BB331 as a direct replacement for the TDK C0603X5R1H331M?

A: Yes. Both parts share identical capacitance (330 pF), voltage rating (50V), and package (0201 / 0603 Metric). The YAGEO part offers improved specifications with X7R temperature coefficient (-55°C to 125°C) and ±5% tolerance versus the original X5R and ±20% tolerance. This represents an upgrade substitution suitable for direct board-level replacement.

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

A: X5R provides ±15% capacitance change across -55°C to 85°C. X7R provides ±15% capacitance change across -55°C to 125°C, offering wider temperature stability. For applications operating within -55°C to 85°C, both coefficients are functionally equivalent. X7R substitutes provide extended temperature margin.

Q: Can I substitute the 25V-rated KGM03AR51E331KH for the 50V-rated original part?

A: Only if your circuit design operates at voltages not exceeding 25V. The KGM03AR51E331KH is voltage-derated and must not be used in applications requiring 50V rating. Verify circuit maximum voltage before selecting this part.

Q: Are the Taiyo Yuden MLASU063SB5331MFNA01 and MSASU063SB5331MFNA01 interchangeable?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (330 pF, ±20%, 50V, X5R, -55°C to 85°C) and package (0201 / 0603 Metric). The MSASU series is specified for SMPS filtering applications while MLASU is specified for medical and non-critical applications. Selection depends on application requirements.

Q: Do all substitute parts meet RoHS and moisture sensitivity requirements?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original part's compliance profile. No additional handling or storage precautions are required beyond standard manufacturing practices.

Q: What inventory considerations apply when selecting substitutes?

A: YAGEO CC0201KRX7R9BB331 offers the highest inventory availability (25,376 pcs), followed by Murata GRM033R71H331KA12D (351,291 pcs). Taiyo Yuden parametric equivalents maintain moderate inventory (737-792 pcs). Vishay Vitramon VJ0201Y331KXACW1BC has limited availability (744 pcs). Verify current stock status with your supplier before design finalization.
