Substitute Part Grouping Explanation

Substitution of the obsolete ERK610Z331MDRZ is based on the following criteria derived from provided specifications:

Primary Substitution Criteria:

• Manufacturer alignment (KEMET)
• Component category (Ceramic Capacitor)
• Regulatory compliance (REACH Unaffected, ECCN EAR99)
• Tariff classification (HTSUS 8532.23.0060)
• Product status (Active production status required for long-term availability)

The recommended substitute part C711U331KZYDDA7301 meets all these criteria while providing active product status and documented electrical specifications. Both parts share identical REACH and ECCN classifications, ensuring regulatory continuity.

Parameter Comparison

Engineering Selection Recommendations

Regulatory Compliance: Both the original ERK610Z331MDRZ and substitute C711U331KZYDDA7301 maintain identical REACH and ECCN classifications (EAR99), ensuring no regulatory barriers to substitution. Both parts fall under the same HTSUS tariff code (8532.23.0060).

Product Availability: The original part is classified as obsolete with limited inventory (711 pcs). The substitute part C711U331KZYDDA7301 is in active production status with higher inventory availability (888 pcs), providing superior long-term supply chain continuity.

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

Electrical and Mechanical Specifications: The substitute part provides complete electrical specifications (330 pF capacitance, ±10% tolerance, 440VAC rating, Y5P temperature coefficient) and mechanical dimensions (8.00mm diameter, 5.00mm height, 10.00mm lead spacing) suitable for through-hole PCB applications.

Frequently Asked Questions (FAQ)

Q: Why is the ERK610Z331MDRZ classified as obsolete? A: The ERK610Z331MDRZ has reached end-of-life status in KEMET's product portfolio. Obsolete classification indicates the manufacturer no longer produces this part, making substitution necessary for future procurement and system maintenance.

Q: What determines compatibility between the original and substitute parts? A: Compatibility is established through shared manufacturer (KEMET), component category (ceramic capacitor), regulatory compliance (REACH Unaffected, ECCN EAR99), and tariff classification (HTSUS 8532.23.0060). The substitute part's active production status ensures ongoing availability.
