Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERK610Z331MERZ is determined by the following critical parameters:

Electrical Parameters: Capacitance value, voltage rating, and temperature coefficient must align with the original specification to ensure circuit functionality and reliability.

Mechanical Parameters: Mounting type, package configuration, lead spacing, and physical dimensions must accommodate existing PCB layouts and assembly processes.

Compliance Parameters: REACH status and ECCN classification must maintain regulatory compliance for the intended application and market.

Manufacturing Status: Active product status ensures ongoing availability and supply chain reliability compared to obsolete components.

The substitute part C712U331KZYDDA7301 meets these criteria through equivalent electrical ratings, compatible mechanical form factor, and active manufacturing status.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The ERK610Z331MERZ is classified as obsolete, whereas C712U331KZYDDA7301 maintains active manufacturing status. Active status ensures continued availability, consistent quality control, and supply chain reliability for production and maintenance applications.

Compliance Alignment: Both components share identical REACH status (REACH Unaffected) and ECCN classification (EAR99), ensuring equivalent regulatory compliance for export, import, and operational use across regulated markets.

Certification Equivalence: Both parts are manufactured by KEMET and classified under the same HTSUS commodity code (8532.23.0060), confirming functional category equivalence and tariff classification consistency.

Selection Basis: Component selection should prioritize C712U331KZYDDA7301 for new designs and ongoing production due to active status and assured supply continuity. Existing inventory of ERK610Z331MERZ may be retained for legacy system maintenance where original part specifications are critical.

Frequently Asked Questions (FAQ)

Q: Can C712U331KZYDDA7301 directly replace ERK610Z331MERZ in existing designs?

A: Direct replacement compatibility depends on circuit-specific electrical requirements (capacitance, voltage, temperature coefficient) and mechanical constraints (mounting type, lead spacing, physical dimensions). The substitute part specifications must be verified against the original design requirements before implementation.

Q: What is the significance of the obsolete status for ERK610Z331MERZ?

A: Obsolete status indicates the part is no longer manufactured by KEMET. This creates supply limitations and potential quality consistency concerns for future procurement. Active alternatives ensure long-term availability and manufacturing consistency.

Q: Are the REACH and ECCN classifications identical between both parts?

A: Yes. Both ERK610Z331MERZ and C712U331KZYDDA7301 share identical REACH status (REACH Unaffected) and ECCN classification (EAR99), confirming equivalent regulatory compliance for the same applications and markets.

Q: What mounting considerations apply to C712U331KZYDDA7301?

A: C712U331KZYDDA7301 is configured as a through-hole mounted component with radial, disc package type. Lead spacing is 0.492" (12.50mm) with formed, kinked leads. PCB layout and assembly processes must accommodate these mechanical specifications.

Q: How do the physical dimensions of the substitute part affect PCB integration?

A: C712U331KZYDDA7301 has a diameter of 0.315" (8.00mm) and seated height of 0.197" (5.00mm). These dimensions must be verified against available PCB space, component density requirements, and thermal management considerations in the target application.
