Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ESK106M350AH2AA are qualified based on the following criteria:

Electrical Compatibility:

• Capacitance value: 10 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: Equal to or greater than 350 V
• Polarization: Polar (exact match required)

Mechanical Compatibility:

• Lead spacing: 0.197" (5.00mm) (exact match required)
• Size / Dimension: 0.394" Dia (10.00mm) (exact match required)
• Height - Seated (Max): 0.669" to 0.689" (within acceptable PCB clearance tolerance)
• Mounting type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)

Regulatory & Compliance:

• RoHS3 Compliant status maintained across all substitutes
• REACH Unaffected status maintained across all substitutes

Substitute parts may differ in operating temperature range, lifetime rating at elevated temperature, ripple current specifications, and ESR characteristics. These differences are permissible when the application requirements do not mandate specific performance in these areas.

Parameter Comparison

Engineering Selection Recommendations

ESH106M350AH2AA (KEMET)

This substitute maintains the same voltage rating (350 V) and capacitance (10 µF) as the primary part. The ESH series offers an extended operating temperature range (-25°C ~ 105°C) and higher lifetime rating (2000 Hrs @ 105°C) compared to the ESK series. Mechanical dimensions are identical. This part is suitable for applications requiring improved thermal performance without voltage or capacitance changes. Product status is Active with ROHS3 compliance.

ESH106M400AH2AA (KEMET)

This substitute provides a higher voltage rating (400 V) while maintaining the same capacitance (10 µF) and mechanical form factor. The ESH series offers extended operating temperature range (-25°C ~ 105°C) and higher lifetime rating (2000 Hrs @ 105°C). This part is suitable for applications where increased voltage margin is required or where thermal performance improvements are beneficial. Product status is Active with ROHS3 compliance.

106CKS400MLQ (Cornell Dubilier / Illinois Capacitor)

This substitute provides a higher voltage rating (400 V) with identical capacitance (10 µF) and lead spacing (5.00mm). The CKS series offers higher ripple current capability (120 mA @ 120 Hz, 216 mA @ 100 kHz) and lower ESR (33.16 Ohm @ 120 Hz). Height is 0.689" (17.50mm), which is 0.020" taller than the primary part. This part is suitable for applications requiring higher ripple current handling or lower impedance characteristics. Product status is Active with ROHS3 compliance.

106CKS450MGBW (Cornell Dubilier / Illinois Capacitor)

This substitute provides the highest voltage rating (450 V) with identical capacitance (10 µF) and lead spacing (5.00mm). The CKS series offers higher ripple current capability (105 mA @ 120 Hz, 189 mA @ 100 kHz) and lower ESR (39.79 Ohm @ 120 Hz). Height is 0.689" (17.50mm), which is 0.020" taller than the primary part. This part is suitable for applications requiring maximum voltage margin or higher ripple current performance. Product status is Active with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can ESH106M350AH2AA be used as a direct replacement for ESK106M350AH2AA?

A: Yes. Both parts have identical electrical specifications (10 µF, 350 V, ±20% tolerance) and mechanical dimensions (0.394" diameter, 0.197" lead spacing, 0.669" height). The ESH series provides enhanced thermal performance with an extended operating temperature range to 105°C and higher lifetime rating at elevated temperature.

Q: What is the difference between the KEMET ESH series and the Cornell Dubilier CKS series substitutes?

A: The KEMET ESH series maintains the same voltage rating options (350 V or 400 V) with extended temperature performance. The Cornell Dubilier CKS series offers higher voltage ratings (400 V or 450 V) and higher ripple current specifications. CKS parts are 0.020" taller (0.689" vs. 0.669") and have specified ESR values, whereas ESK and ESH series do not have ESR specifications provided.

Q: Are the height differences between substitute parts significant?

A: The ESK106M350AH2AA and KEMET ESH series parts have a maximum seated height of 0.669" (17.00mm). The Cornell Dubilier CKS series parts have a maximum seated height of 0.689" (17.50mm), a difference of 0.020" (0.50mm). This difference must be evaluated against PCB clearance requirements and component placement constraints in the specific application.

Q: Can I use a higher voltage-rated substitute in place of the 350 V primary part?

A: Yes. Substitutes with higher voltage ratings (400 V or 450 V) are electrically compatible with circuits designed for 350 V operation. Higher voltage ratings provide additional safety margin and do not degrade circuit performance. The capacitance value (10 µF) and tolerance (±20%) remain unchanged.

Q: What are the ripple current differences between substitute parts?

A: The primary ESK106M350AH2AA is rated for 70 mA @ 120 Hz and 98 mA @ 10 kHz. The KEMET ESH series provides 80 mA @ 120 Hz and 128 mA @ 100 kHz. The Cornell Dubilier CKS series provides higher ripple current: 106CKS400MLQ offers 120 mA @ 120 Hz and 216 mA @ 100 kHz; 106CKS450MGBW offers 105 mA @ 120 Hz and 189 mA @ 100 kHz. Higher ripple current capability is beneficial in applications with significant AC current components.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (ESH106M350AH2AA, ESH106M400AH2AA, 106CKS400MLQ, and 106CKS450MGBW) are ROHS3 compliant and REACH unaffected, matching the compliance status of the primary part ESK106M350AH2AA.

Q: What is the operating temperature difference between the primary part and substitutes?

A: The primary ESK106M350AH2AA operates from -25°C to 85°C. The KEMET ESH series substitutes extend the upper operating limit to 105°C. The Cornell Dubilier CKS series substitutes maintain the -25°C to 85°C range. Extended temperature operation may be beneficial in applications subject to elevated ambient conditions or self-heating effects.

Q: Can I substitute based on ripple current requirements alone?

A: No. Substitution must maintain electrical compatibility (capacitance, tolerance, voltage rating, polarization) and mechanical compatibility (lead spacing, diameter, height, mounting type, package type). Ripple current is a secondary consideration used to select among electrically and mechanically compatible alternatives.
