Substitute Part Grouping Explanation

Substitution of the ERK610Z331MTCR is based on the following criteria derived from the provided parameters:

Primary Substitution Basis:

• Manufacturer alignment (KEMET)
• Ceramic capacitor category classification
• Compliance equivalence (REACH Unaffected, ECCN EAR99, HTSUS 8532.23.0060)
• Active product status of substitute component

The substitute part C717U331KZYDCA7301 meets these criteria as a KEMET ceramic capacitor with identical regulatory compliance classification and active production status, ensuring long-term availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The C717U331KZYDCA7301 is the manufacturer-recommended substitute for the obsolete ERK610Z331MTCR. Selection of this substitute is justified on the following engineering grounds:

Regulatory Compliance: Both components share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8532.23.0060), ensuring equivalent compliance standing in supply chain and export documentation.

Manufacturer Continuity: Both parts are manufactured by KEMET, maintaining design consistency and quality assurance standards within the same product ecosystem.

Product Lifecycle Status: The substitute component C717U331KZYDCA7301 holds active product status, ensuring continued availability, technical support, and supply chain reliability. The original ERK610Z331MTCR is obsolete and subject to inventory depletion.

Component Category: Both are ceramic capacitors, maintaining functional category equivalence for circuit design applications.

Frequently Asked Questions (FAQ)

Q: Why is the ERK610Z331MTCR classified as obsolete?

A: The ERK610Z331MTCR has reached end-of-life status in KEMET's product portfolio. Obsolete classification indicates the manufacturer no longer produces this component, making substitution necessary for long-term system support.

Q: What makes C717U331KZYDCA7301 a valid substitute?

A: The substitute shares identical manufacturer (KEMET), component category (ceramic capacitor), and regulatory compliance parameters (REACH Unaffected, ECCN EAR99, HTSUS 8532.23.0060). Additionally, it maintains active production status, ensuring supply availability.

Q: Are there differences in electrical specifications between the two parts?

A: The original ERK610Z331MTCR does not have detailed electrical specifications provided in the reference data. The substitute C717U331KZYDCA7301 is specified as 330 pF ±10% at 440VAC with Y5P (B) temperature coefficient. Verification against original circuit requirements is necessary before implementation.

Q: What is the physical form factor of the substitute?

A: The C717U331KZYDCA7301 is a through-hole mounted radial disc ceramic capacitor with 0.315" diameter (8.00mm), 0.197" seated height (5.00mm), and 0.295" lead spacing (7.50mm) with kinked formed leads.

Q: Are both components compliant with REACH regulations?

A: Yes, both ERK610Z331MTCR and C717U331KZYDCA7301 are classified as REACH Unaffected, indicating compliance with REACH regulatory requirements.

Q: What is the inventory status of these components?

A: ERK610Z331MTCR has 866 pieces in stock as new original inventory. C717U331KZYDCA7301 has 870 pieces in stock as new original inventory. Both are available for immediate procurement.
