108KXM010MLQ Equivalent & Substitute Parts Reference

Part Overview

The 108KXM010MLQ is a 1000 µF, 10 V aluminum electrolytic capacitor in radial configuration, manufactured by Cornell Dubilier / Illinois Capacitor. This component is designed for bypass and decoupling applications in electronic circuits requiring reliable energy storage and filtering. The part is currently in active production status with 701 units available in stock.

Finding equivalent and substitute parts becomes necessary when the primary component reaches end-of-life, experiences extended lead times, or when design optimization requires enhanced electrical performance characteristics. Substitute parts must maintain compatibility across critical electrical parameters including capacitance value, voltage rating, physical dimensions, and thermal specifications to ensure reliable operation in target applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 108KXM010MLQ are identified based on strict equivalence across the following critical parameters:

Mandatory Compatibility Parameters:

• Capacitance value: 1000 µF (±20% tolerance)
• Voltage rating: minimum 10 V (equal or higher)
• Case diameter: 0.394" (10.00mm)
• Case height: 0.689" (17.50mm)
• Lead spacing: 0.197" (5.00mm)
• Package type: Radial, Can configuration
• Mounting type: Through Hole
• Polarization: Polar

The two identified substitute parts meet these dimensional and electrical compatibility requirements while offering improved or equivalent performance characteristics. Substitution validity depends on matching the physical footprint and electrical ratings to ensure proper circuit board assembly and circuit operation without design modification.

Engineering Selection Recommendations

ELXZ100ELL102MJ16S (Chemi-Con LXZ Series)

This substitute offers enhanced thermal durability with 5000 hours lifetime at 105°C compared to the 4000 hours specification of the original part. The part maintains identical voltage rating, capacitance, and physical dimensions. AEC-Q200 automotive qualification rating indicates compliance with automotive reliability standards. ROHS3 compliance and REACH unaffected status align with the original part's regulatory position. Chemi-Con is an established manufacturer with demonstrated production capacity (4759 units in stock).

UPA1C102MPD (Nichicon UPA Series)

This substitute provides enhanced voltage headroom with a 16 V rating against the original 10 V specification, offering design margin for circuits operating near rated voltage limits. The component features superior impedance at 49 mOhms and higher ripple current capability at 120 Hz (930 mA) compared to the original specification. Physical footprint and mounting characteristics remain identical. Current production status is active with 2658 units available. Note that REACH status is affected, requiring evaluation in applications subject to REACH-compliant material sourcing requirements.

Frequently Asked Questions (FAQ)

Q: Can ELXZ100ELL102MJ16S be used as a direct replacement for 108KXM010MLQ?

A: Yes. Both parts share identical capacitance (1000 µF), voltage rating (10 V), physical dimensions, and lead spacing. The ELXZ100ELL102MJ16S provides equivalent functionality with extended thermal lifetime (5000 Hrs vs 4000 Hrs @ 105°C). No circuit board redesign is required.

Q: What is the difference between the two substitute parts?

A: The primary differences are voltage rating and electrical performance. UPA1C102MPD operates at 16 V versus 10 V for ELXZ100ELL102MJ16S, providing higher voltage capability. UPA1C102MPD also features lower impedance (49 mOhms vs 68 mOhms) and higher ripple current capability at 120 Hz. Both maintain identical physical dimensions and mounting compatibility.

Q: Which substitute should be selected for new designs?

A: Selection depends on circuit requirements. For 10 V applications requiring automotive qualification, ELXZ100ELL102MJ16S is specified. For applications requiring voltage margin or higher ripple current handling, UPA1C102MPD is appropriate. Both parts meet ROHS3 compliance; however, REACH status differs and should be evaluated against material sourcing requirements.

Q: Are there any thermal or frequency-dependent differences?

A: ELXZ100ELL102MJ16S specifies 5000 hour thermal lifetime versus 4000 hours for both the original and UPA1C102MPD. Ripple current ratings vary across all three parts at both 120 Hz and 100 kHz, reflecting differences in internal resistance characteristics. Applications with elevated ripple current demands should reference the detailed ripple current specifications in the parameter comparison table.

Q: What is the impact of different ESR values?

A: ESR differences affect voltage drop and heat generation under ripple current conditions. UPA1C102MPD features the lowest impedance (49 mOhms), potentially reducing power loss in high-frequency ripple environments. Physical design must account for the specific impedance characteristic of the selected substitute to ensure thermal stability within target applications.
