Substitute Part Grouping Explanation

Substitution of the obsolete ERP610W331KERZ is determined by the following criteria established by KEMET manufacturer recommendations:

Primary Substitution Criteria:

• Capacitance value: 330 pF
• Tolerance: ±20%
• Voltage rating: 760V
• Temperature coefficient: Y5U (E)
• Mounting type: Through Hole
• Package style: Radial, Disc
• Regulatory compliance: REACH Unaffected, ECCN EAR99
• Safety ratings: X1, Y1 classifications

The substitute part C722U331MWWDDA7301 meets all specified electrical and mechanical parameters required for direct replacement in applications originally designed for the ERP610W331KERZ.

Parameter Comparison

Engineering Selection Recommendations

The C722U331MWWDDA7301 is designated as the KEMET manufacturer-recommended substitute for the obsolete ERP610W331KERZ. This recommendation is based on:

Compliance Alignment:

• Both parts maintain identical REACH compliance status (REACH Unaffected)
• Both parts share the same ECCN classification (EAR99)
• Both parts fall under the same HTSUS commodity code (8532.23.0060)

Product Status Consideration: The substitute part C722U331MWWDDA7301 holds Active product status, ensuring continued availability and supply chain reliability. This addresses the primary limitation of the obsolete ERP610W331KERZ, which is no longer manufactured.

Inventory Availability: While the original ERP610W331KERZ maintains current stock of 1159 units, the substitute C722U331MWWDDA7301 is available with 843 units in inventory, supporting both immediate replacement needs and long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Why is the ERP610W331KERZ classified as obsolete?

A: The ERP610W331KERZ has reached end-of-life status and is no longer manufactured by KEMET. Obsolete classification indicates the part is no longer in active production, though existing inventory may remain available.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility for ceramic capacitors in this category is determined by capacitance value (330 pF), tolerance (±20%), voltage rating (760V), and temperature coefficient (Y5U (E)). The substitute part C722U331MWWDDA7301 matches all these electrical specifications.

Q: Are the mechanical dimensions identical between the original and substitute parts?

A: The substitute part C722U331MWWDDA7301 specifies the following mechanical parameters: 0.354" diameter (9.00mm), 0.551" maximum seated height (14.00mm), and 0.492" lead spacing (12.50mm). These dimensions are consistent with Through Hole Radial Disc package standards. The original part specifications for mechanical dimensions are not provided in available documentation.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the ERP610W331KERZ and C722U331MWWDDA7301 maintain REACH Unaffected status and share identical ECCN (EAR99) and HTSUS (8532.23.0060) classifications, ensuring equivalent regulatory compliance.

Q: What is the operating temperature range for the substitute part?

A: The C722U331MWWDDA7301 operates across a temperature range of -40°C to 125°C, consistent with Y5U (E) temperature coefficient specifications for ceramic capacitors.

Q: Are there any safety rating differences between the parts?

A: The substitute part C722U331MWWDDA7301 carries X1 and Y1 safety ratings, indicating suitability for safety-critical applications. The original part safety ratings are not specified in available documentation.

Q: What mounting configuration is used for the substitute part?

A: The C722U331MWWDDA7301 uses Through Hole mounting with Formed Leads - Kinked lead style, standard for Radial Disc ceramic capacitor packages.
