Engineering Selection Recommendations

EKZE101ELL331MK35S is the qualified substitute for KZE100VB331M12X35LL based on the following engineering criteria:

Functional Equivalence: All electrical parameters match exactly, including capacitance, voltage rating, tolerance, ripple current specifications, and impedance. Thermal performance and operating temperature range are identical.

Mechanical Compatibility: Lead spacing and diameter are identical. Height variation of 0.059" (1.50 mm) is within acceptable tolerance for through-hole PCB mounting applications and does not compromise board-level integration.

Product Status Advantage: EKZE101ELL331MK35S carries active product status, ensuring continued availability and supply chain support. The original KZE100VB331M12X35LL is obsolete.

Regulatory Compliance: EKZE101ELL331MK35S is ROHS3 compliant, providing improved environmental and regulatory alignment compared to the non-compliant original part. Both parts maintain REACH Unaffected status and EAR99 classification.

Supply Availability: EKZE101ELL331MK35S has 677 units in stock, supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can EKZE101ELL331MK35S be used as a direct replacement for KZE100VB331M12X35LL in existing designs?

A: Yes. EKZE101ELL331MK35S is a direct functional equivalent. All electrical specifications, thermal ratings, and mechanical dimensions for PCB mounting are identical. The 1.50 mm height difference does not affect through-hole mounting compatibility.

Q: What is the significance of the height difference between these parts?

A: The original KZE100VB331M12X35LL has a seated height of 1.378" (35.00 mm), while EKZE101ELL331MK35S measures 1.437" (36.50 mm). This 0.059" (1.50 mm) variation is within standard mechanical tolerance for radial aluminum electrolytic capacitors and does not impact PCB clearance or component placement in typical applications.

Q: Why is the original part marked as obsolete?

A: The KZE100VB331M12X35LL is classified as obsolete, indicating that Chemi-Con has discontinued active production and support. EKZE101ELL331MK35S represents the current active equivalent, ensuring long-term supply chain continuity.

Q: Are there compliance differences between these parts?

A: Yes. KZE100VB331M12X35LL is RoHS non-compliant, while EKZE101ELL331MK35S is ROHS3 compliant. Both maintain REACH Unaffected status. For applications requiring RoHS compliance, EKZE101ELL331MK35S is the appropriate selection.

Q: What parameters must match exactly for substitution eligibility?

A: Capacitance (330 µF), voltage rating (100 V), tolerance (±20%), operating temperature range (-40°C ~ 105°C), lifetime rating (5000 Hrs @ 105°C), ripple current specifications, lead spacing (5.00 mm), diameter (12.50 mm), mounting type (through-hole), and package type (radial, can) must all match exactly. Minor height variation is acceptable within mechanical envelope constraints.

Q: Is the impedance specification identical between these parts?

A: Yes. Both KZE100VB331M12X35LL and EKZE101ELL331MK35S have an impedance of 36 mOhms, ensuring equivalent electrical performance in ripple current filtering and power supply applications.
