Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERP610W331MTE0 is determined by alignment of the following critical parameters:

Electrical Specifications:

• Capacitance value and tolerance
• Voltage rating (rated voltage must equal or exceed original specification)
• Temperature coefficient classification
• Operating temperature range

Physical & Mechanical Specifications:

• Mounting type (Through Hole compatibility)
• Package form factor (Radial, Disc configuration)
• Lead style and spacing
• Physical dimensions

Compliance & Regulatory:

• REACH compliance status
• ECCN classification
• HTSUS commodity code alignment

The substitute part C721U331MWWDCAWL50 shares the same manufacturer (KEMET), regulatory classification (REACH Unaffected, EAR99), and commodity code (8532.23.0060), establishing baseline compatibility for substitution consideration.

Parameter Comparison

Engineering Selection Recommendations

Regulatory & Compliance Alignment: The substitute part C721U331MWWDCAWL50 maintains identical REACH compliance status (REACH Unaffected), ECCN classification (EAR99), and HTSUS commodity code (8532.23.0060) as the original ERP610W331MTE0. This ensures no change in regulatory or export control requirements.

Product Status Consideration: The original part ERP610W331MTE0 carries obsolete status with limited remaining inventory (866 pcs). The substitute C721U331MWWDCAWL50 is classified as Active, providing assured long-term availability and supply chain continuity.

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

Electrical & Mechanical Specifications: The substitute part provides documented electrical specifications (330 pF capacitance, ±20% tolerance, 760V rated voltage, Y5U temperature coefficient) and mechanical specifications (Through Hole mounting, Radial Disc package, Formed Leads - Kinked configuration) suitable for direct circuit board integration.

Frequently Asked Questions (FAQ)

Q: Can C721U331MWWDCAWL50 directly replace ERP610W331MTE0 in existing circuit designs?

A: Direct substitution is supported based on shared manufacturer (KEMET), identical regulatory classification (REACH Unaffected, EAR99), and matching commodity code (8532.23.0060). The substitute part is Active status, ensuring supply availability. Circuit-level compatibility depends on verification that the documented electrical specifications (330 pF, ±20%, 760V, Y5U) and mechanical specifications (Through Hole, Radial Disc, Formed Leads - Kinked) align with original design requirements.

Q: What is the significance of the Y5U temperature coefficient classification?

A: Y5U is a temperature coefficient classification for ceramic capacitors indicating specific capacitance variation characteristics across the operating temperature range (-40°C ~ 125°C). This classification is a standard parameter for ceramic capacitor selection and must be verified against original design specifications.

Q: Are there any lead spacing or physical dimension differences between the original and substitute parts?

A: The substitute part C721U331MWWDCAWL50 specifies lead spacing of 0.394" (10.00mm), radial disc package configuration, and maximum seated height of 0.551" (14.00mm). These dimensions must be verified against original PCB layout and mechanical clearance requirements to ensure physical compatibility.

Q: Does the substitute part maintain the same safety ratings as the original?

A: The substitute part C721U331MWWDCAWL50 is rated for X1 and Y1 safety classifications with 760V rated voltage, suitable for safety-critical applications. Original design safety requirements must be confirmed to ensure equivalent performance.

Q: What is the lead style difference, and does it affect installation?

A: The substitute part features Formed Leads - Kinked configuration, a standard lead style for radial disc ceramic capacitors. This style is compatible with standard through-hole PCB assembly processes. Original design specifications should be reviewed to confirm compatibility with existing assembly procedures.
