Substitute Part Grouping Explanation

Substitution for the ERP610W331MDB0 is determined by the following criteria derived from provided specifications:

Primary Substitution Criteria:

• Manufacturer: KEMET (same manufacturer preferred for consistency)
• Component Type: Ceramic Capacitor
• Product Status: Active (to ensure ongoing availability)
• Regulatory Compliance: REACH Unaffected and ECCN EAR99 (matching compliance profile)
• HTSUS Classification: 8532.23.0060 (same tariff classification)

The substitute part C721U331MWWDAAWL50 meets all these criteria and is currently in active production status with confirmed inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The C721U331MWWDAAWL50 is the manufacturer-recommended substitute for the obsolete ERP610W331MDB0. Selection of this substitute is supported by the following factors:

Compliance Alignment: Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99), ensuring regulatory continuity in procurement and deployment.

Manufacturer Consistency: Both components are manufactured by KEMET, maintaining supply chain consistency and quality assurance protocols.

Product Status: The substitute part holds active production status with higher inventory availability (1112 Pcs vs. 634 Pcs), providing superior long-term supply security compared to the obsolete main part.

Tariff Classification: Both parts share the same HTSUS code (8532.23.0060), indicating equivalent trade classification and duty treatment.

The substitute part provides specified electrical parameters (330 pF capacitance, ±20% tolerance, 760V rated voltage, Y5U temperature coefficient) and mechanical specifications (Through Hole mounting, Radial Disc package, 9.00mm diameter, 10.00mm lead spacing) that establish functional equivalence within the ceramic capacitor category.

Frequently Asked Questions (FAQ)

Q: Why is the ERP610W331MDB0 classified as obsolete?

A: The ERP610W331MDB0 has reached end-of-life status in KEMET's product portfolio. Obsolete classification indicates the manufacturer no longer produces this part, making substitute identification necessary for continued system support and new procurement activities.

Q: What determines compatibility between the main part and substitute?

A: Compatibility is established through matching manufacturer (KEMET), component category (Ceramic Capacitor), regulatory compliance (REACH Unaffected, EAR99), and tariff classification (HTSUS 8532.23.0060). The substitute part C721U331MWWDAAWL50 satisfies all these criteria.

Q: What are the key electrical specifications of the substitute part?

A: The C721U331MWWDAAWL50 provides 330 pF capacitance with ±20% tolerance, 760V rated voltage, Y5U temperature coefficient, and operating temperature range of -40°C to 125°C.

Q: What is the mechanical package configuration of the substitute?

A: The substitute part uses Through Hole mounting with Radial Disc package configuration. Physical dimensions include 9.00mm diameter, 6.00mm maximum seated height, and 10.00mm lead spacing with straight lead style.

Q: How does inventory availability compare?

A: The substitute part C721U331MWWDAAWL50 has 1112 pieces in stock compared to 634 pieces for the obsolete main part, providing improved supply security for ongoing procurement requirements.

Q: Are there any compliance or certification differences?

A: Both parts maintain identical compliance profiles: REACH Unaffected status and EAR99 ECCN classification. No compliance barriers exist for substitution.
