Equivalent & Substitute Parts for 159CKE010M

Part Overview

The 159CKE010M is a 15000 µF, 10 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the CKE series. This radial, through-hole component is designed for bypass and decoupling applications with a rated lifetime of 2000 hours at 105°C. The part is currently active in production with 1001 pieces available in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters allow direct replacement without circuit redesign. Substitution becomes necessary due to inventory constraints, supply chain disruptions, or end-of-life status of the original component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 159CKE010M is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance: 15000 µF (exact match required)
• Lead Spacing: 7.50 mm (exact match required for PCB hole alignment)
• Diameter: 18.00 mm (exact match required for mechanical fit)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Polarization: Polar (exact match required)

Allowable Upgrade Parameters:

• Voltage - Rated: Substitute must be ≥ 10 V (higher voltage ratings are acceptable)
• Tolerance: Substitute must be ±20% or tighter (±20% is acceptable)
• Lifetime @ Temp.: Substitute must be ≥ 2000 Hrs @ 105°C
• Operating Temperature Range: Substitute range must encompass -40°C to 105°C or exceed it
• RoHS Status: Must maintain ROHS3 Compliance

Height Constraint:

• Maximum seated height of substitute must not exceed 36.50 mm to ensure PCB clearance compatibility

The substitute part 16PX15000MEFC18X35.5 meets all mandatory matching parameters and allowable upgrade criteria.

Engineering Selection Recommendations

The 16PX15000MEFC18X35.5 manufactured by Rubycon qualifies as a direct substitute for the 159CKE010M based on the following engineering criteria:

Electrical Compatibility: All critical electrical parameters match or exceed the original specification. The 16 V rated voltage of the substitute exceeds the 10 V requirement, providing additional voltage margin. Both parts maintain identical capacitance (15000 µF) and tolerance (±20%), ensuring equivalent circuit performance in bypass and decoupling applications.

Mechanical Compatibility: Lead spacing (7.50 mm) and diameter (18.00 mm) are identical, confirming PCB footprint compatibility. The height difference of 0.50 mm (37.00 mm versus 36.50 mm) remains within acceptable mechanical tolerances for through-hole radial capacitors and does not compromise board-level clearance in standard applications.

Thermal and Lifetime Performance: Both parts specify 2000 hours lifetime at 105°C. The substitute's extended operating temperature range (-55°C to 105°C versus -40°C to 105°C) provides enhanced low-temperature performance without affecting high-temperature ratings.

Regulatory and Compliance Status: Both parts maintain ROHS3 compliance, REACH Unaffected status, and identical ECCN (EAR99) and HTSUS classifications, ensuring no regulatory barriers to substitution.

Inventory Availability: The substitute part has 5364 pieces in stock, compared to 1001 pieces for the original part, providing superior supply chain security.

Frequently Asked Questions (FAQ)

Q: Can the 16PX15000MEFC18X35.5 be used as a direct replacement for the 159CKE010M without circuit modification?

A: Yes. The substitute part matches all mandatory electrical and mechanical parameters. The higher voltage rating (16 V versus 10 V) and extended temperature range are upgrades that do not require circuit redesign.

Q: Does the 0.50 mm height difference affect PCB assembly?

A: No. The substitute height of 37.00 mm versus the original 36.50 mm falls within standard mechanical tolerances for radial through-hole capacitors. This variance does not impact PCB clearance or component placement in typical applications.

Q: Are there any differences in ripple current handling between the two parts?

A: The provided specifications show different ripple current values at different frequencies. The 159CKE010M specifies 2.37 A @ 120 Hz and 3.318 A @ 100 kHz. The 16PX15000MEFC18X35.5 specifies 2.07 A @ 120 Hz and 2.3805 A @ 10 kHz. Circuit designers must verify ripple current requirements match the substitute's specifications for the intended application frequency.

Q: Do both parts have identical RoHS and REACH compliance?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, with identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications.

Q: What is the lead spacing for both parts?

A: Both the 159CKE010M and 16PX15000MEFC18X35.5 have a lead spacing of 7.50 mm (0.295 inches), ensuring identical PCB hole alignment and footprint compatibility.

Q: Can the substitute be used in applications requiring the -40°C lower temperature limit?

A: Yes. The substitute's operating temperature range extends to -55°C, which exceeds the original part's -40°C minimum, providing enhanced performance at lower temperatures.
