Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CL31B472KGFNFNE are classified based on electrical and mechanical parameter alignment. Direct substitutes maintain identical specifications across capacitance (4700 pF), tolerance (±10%), voltage rating (500V), temperature coefficient (X7R), package format (1206), and operating temperature range (-55°C to 125°C). These parts are interchangeable in applications where the original specification is required.

Upgrade substitutes provide enhanced voltage ratings (630V or 1000V) while maintaining all other core parameters. These parts are suitable for applications where higher voltage margin is beneficial, though they are classified as Not For New Designs by their manufacturers.

The substitution logic is based strictly on:

• Capacitance value matching (4700 pF)
• Tolerance compatibility (±10%)
• Voltage rating (500V minimum for direct substitutes; 630V or 1000V for upgrades)
• Temperature coefficient (X7R)
• Package format (1206 / 3216 Metric)
• Operating temperature range (-55°C to 125°C)
• Surface mount MLCC mounting type

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Active Status):

CC1206KKX7RBBB472 (YAGEO) and KGM31DR72H472KU (KYOCERA AVX) are direct electrical and mechanical equivalents to the CL31B472KGFNFNE. Both parts maintain identical capacitance, tolerance, voltage rating, temperature coefficient, and package specifications. Both manufacturers provide ROHS3 compliance and MSL 1 rating. These parts are suitable for immediate substitution in production designs and new applications. KYOCERA AVX part offers higher inventory availability (19,366 units) compared to YAGEO (15,362 units).

Upgrade Substitutes (Not For New Designs):

GRM31BR72J472KW01L (Murata, 630V) and GRM31BR73A472KW01L (Murata, 1000V) provide enhanced voltage ratings while maintaining all other electrical parameters. These parts are classified as Not For New Designs by Murata Electronics. Selection of upgrade substitutes is appropriate only for existing designs where higher voltage margin is required and where the Not For New Designs status does not conflict with procurement policies. Both upgrade parts maintain ROHS3 compliance and MSL 1 rating.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification, matching the original part's regulatory profile. Moisture Sensitivity Level 1 (Unlimited) is consistent across all options, eliminating moisture handling concerns during assembly.

Frequently Asked Questions (FAQ)

Q: Can CC1206KKX7RBBB472 be used as a direct replacement for CL31B472KGFNFNE?

A: Yes. CC1206KKX7RBBB472 is a direct substitute. Both parts share identical electrical specifications (4700 pF, ±10%, 500V, X7R) and mechanical package (1206). Physical thickness differs by 0.002" (0.05mm), which is within typical PCB assembly tolerances and does not affect functionality.

Q: What is the difference between direct substitutes and upgrade substitutes?

A: Direct substitutes (CC1206KKX7RBBB472, KGM31DR72H472KU) maintain the 500V rating and Active product status. Upgrade substitutes (GRM31BR72J472KW01L at 630V, GRM31BR73A472KW01L at 1000V) provide higher voltage ratings but carry Not For New Designs status. Upgrades are suitable only for existing designs requiring additional voltage margin.

Q: Are there any physical compatibility issues when substituting parts?

A: All substitute parts use the 1206 (3216 Metric) package with identical footprint dimensions (0.126" L × 0.063" W). Thickness variations range from 0.049" to 0.061", which fall within standard PCB assembly clearances. No PCB layout modifications are required.

Q: Which substitute offers the best inventory availability?

A: KYOCERA AVX KGM31DR72H472KU provides the highest inventory among direct substitutes with 19,366 units in stock, followed by YAGEO CC1206KKX7RBBB472 with 15,362 units. Both exceed the original Samsung part's availability relative to typical procurement cycles.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 rating, matching the original CL31B472KGFNFNE specifications. Regulatory and environmental compliance is consistent across all options.

Q: Can upgrade substitutes be used in applications designed for 500V rated capacitors?

A: Upgrade substitutes with higher voltage ratings (630V or 1000V) are electrically compatible with 500V applications. However, their Not For New Designs status should be verified against procurement and design policies before implementation in production designs.
