Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 188KXM035M is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 1800 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: 35 V (exact match required)
• Polarization: Polar (exact match required)

Mechanical Compatibility Criteria:

• Package type: Radial, Can (exact match required)
• Lead spacing: 0.295" (7.50mm) (exact match required)
• Diameter: 0.630" (16.00mm) (exact match required)
• Height: 1.063" (27.00mm) maximum seated height (substitute height must not exceed this dimension)

Environmental & Compliance Criteria:

• Operating temperature range: -55°C ~ 105°C (substitute must cover or exceed this range)
• RoHS3 compliance (required for regulatory alignment)

The identified substitute parts meet all electrical and mechanical requirements. Variations in ESR, ripple current ratings, impedance, and lifetime specifications do not disqualify substitution when core parameters align.

Engineering Selection Recommendations

188KXM035M (Cornell Dubilier / Illinois Capacitor)

Primary selection for general purpose applications. Active product status with established supply chain. ROHS3 compliant. Suitable for standard industrial and consumer electronics requiring 1800 µF, 35 V aluminum electrolytic capacitor in radial configuration.

EEU-FC1V182 (Panasonic Electronic Components)

Direct substitute with identical electrical and mechanical specifications. Active product status. Carries AEC-Q200 automotive qualification rating. ROHS3 compliant. Lower impedance (22 mOhms vs. 110.5 mOhms) and reduced ripple current at high frequency compared to main part. Suitable for applications where automotive-grade reliability is required or where lower impedance characteristics are beneficial.

ELXZ350ELL182ML25S (Chemi-Con)

Upgrade substitute with extended lifetime rating (8000 Hrs @ 105°C vs. 5000 Hrs). Active product status. Carries AEC-Q200 automotive qualification rating. ROHS3 compliant. Seated height 1.043" (26.50mm) is within maximum specification. Lower impedance (22 mOhms) and reduced ripple current at low frequency. Suitable for applications requiring extended operational life or automotive-grade performance specifications.

All three parts are ROHS3 compliant and maintain Active product status, ensuring regulatory alignment and continued availability.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC1V182 be used as a direct replacement for 188KXM035M?

A: Yes. Both parts share identical capacitance (1800 µF), tolerance (±20%), voltage rating (35 V), operating temperature range (-55°C ~ 105°C), package type (Radial, Can), lead spacing (0.295" / 7.50mm), and diameter (0.630" / 16.00mm). Mechanical and electrical compatibility is confirmed.

Q: What is the difference between the three parts?

A: The 188KXM035M features 110.5 mOhm ESR at 120 Hz with 5000 hour lifetime. The EEU-FC1V182 and ELXZ350ELL182ML25S both feature 22 mOhm impedance. The ELXZ350ELL182ML25S provides extended lifetime (8000 hours vs. 5000 hours at 105°C). Both Panasonic and Chemi-Con parts carry AEC-Q200 automotive qualification.

Q: Does the height difference between 188KXM035M and ELXZ350ELL182ML25S affect compatibility?

A: No. The ELXZ350ELL182ML25S seated height is 1.043" (26.50mm), which is within the maximum specification of 1.063" (27.00mm) for the 188KXM035M. The part fits within the same PCB footprint and mounting envelope.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Which part should be selected for automotive applications?

A: Both EEU-FC1V182 and ELXZ350ELL182ML25S carry AEC-Q200 automotive qualification. The ELXZ350ELL182ML25S provides extended lifetime (8000 hours) for applications requiring enhanced reliability over extended operational periods.

Q: Is ESR (Equivalent Series Resistance) a substitution-limiting factor?

A: No. ESR variation does not disqualify substitution when capacitance, voltage, tolerance, package, and mechanical dimensions are identical. ESR differences may affect ripple current handling and thermal performance but do not prevent functional replacement in general purpose applications.
