Equivalent & Substitute Parts for SEK153M010ST

Part Overview

The SEK153M010ST is a 15000 µF, 10 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as Active product status and is designed for general purpose applications. The capacitor features a 40 mOhm equivalent series resistance at 120 Hz and is rated for 2000 hours at 105°C operating temperature.

Substitute parts become necessary when the primary component reaches end-of-life inventory, when supply chain constraints occur, or when design requirements allow for alternative manufacturers meeting the same electrical and mechanical specifications. The parts listed below maintain compatibility with the SEK153M010ST based on matching capacitance, voltage rating, tolerance, package type, and thermal performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SEK153M010ST is determined by strict adherence to the following parameters:

Primary Matching Criteria (Mandatory):

• Capacitance: 15000 µF
• Voltage Rating: 10 V
• Tolerance: ±20%
• Package Type: Radial, Can
• Mounting Type: Through Hole
• Lead Spacing: 0.295" (7.50mm)
• Size / Dimension: 0.709" Dia (18.00mm)
• Operating Temperature Range: -55°C ~ 105°C
• Polarization: Polar
• RoHS Status: ROHS3 Compliant

Secondary Compatibility Parameters:

• Lifetime @ 105°C: 2000 hours minimum
• Height - Seated (Max): Within acceptable PCB clearance limits

All substitute parts listed below meet these mandatory criteria. Variations in ESR, ripple current ratings, and impedance values are noted but do not disqualify substitution when the primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

SEK153M010ST (Primary Component): The SEK153M010ST maintains Active product status, indicating ongoing manufacturer support and availability. This component is the preferred choice for new designs and applications requiring long-term supply assurance.

UPW1A153MHD (Nichicon - Extended Lifetime): The UPW1A153MHD is electrically and mechanically compatible with the SEK153M010ST. This substitute offers an extended lifetime rating of 8000 hours at 105°C compared to the 2000-hour rating of the primary part. However, the UPW1A153MHD carries a "Not For New Designs" product status, indicating the manufacturer has discontinued active development. This part is suitable for replacement applications in existing designs where extended thermal performance is beneficial and supply is available.

UKA1A153MHD (Nichicon - Audio Applications): The UKA1A153MHD meets all mandatory electrical and mechanical compatibility parameters. This substitute is designated for audio applications and carries "Not For New Designs" status. The component is suitable for direct replacement in existing audio circuit applications where the SEK153M010ST is currently deployed.

ECA-1AHG153 (Panasonic - Active Status): The ECA-1AHG153 maintains Active product status and is manufactured by Panasonic Electronic Components. This substitute meets all mandatory compatibility criteria and offers the lowest seated height at 1.476" (37.50mm), providing additional PCB clearance margin. The Panasonic component is suitable for both new designs and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can UPW1A153MHD be used as a direct replacement for SEK153M010ST?

A: Yes. The UPW1A153MHD meets all mandatory electrical and mechanical parameters: 15000 µF capacitance, 10 V voltage rating, ±20% tolerance, radial can package, 0.295" lead spacing, 0.709" diameter, and -55°C to 105°C operating range. The primary difference is the extended 8000-hour lifetime at 105°C versus 2000 hours for the SEK153M010ST. Physical height is 1.575" (40.00mm) compared to 1.654" (42.00mm), providing additional PCB clearance.

Q: What is the significance of "Not For New Designs" status?

A: "Not For New Designs" indicates the manufacturer has ceased active development and support for that component. Existing inventory may be available, but long-term supply cannot be guaranteed. These parts are suitable for replacement in existing applications but should not be selected for new product designs requiring extended production lifecycles.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts—UKA1A153MHD, UPW1A153MHD, and ECA-1AHG153—are ROHS3 compliant, matching the compliance status of the SEK153M010ST.

Q: How do height differences affect PCB compatibility?

A: The SEK153M010ST has a maximum seated height of 1.654" (42.00mm). Substitute parts have lower heights: UPW1A153MHD at 1.575" (40.00mm), UKA1A153MHD at 1.634" (41.50mm), and ECA-1AHG153 at 1.476" (37.50mm). Lower heights provide additional clearance above the PCB. All heights remain within typical through-hole component spacing standards. Verify specific PCB layout constraints before selection.

Q: Do ESR and ripple current differences affect substitution?

A: ESR and ripple current ratings are performance characteristics that do not disqualify substitution when primary electrical parameters match. The SEK153M010ST specifies 40 mOhm ESR at 120 Hz. Substitute parts do not provide ESR specifications in all cases. Ripple current ratings vary among substitutes but remain within acceptable ranges for general purpose and audio applications. Applications with specific ripple current requirements should reference the detailed ripple current specifications provided for each part.

Q: Which substitute is recommended for new designs?

A: The ECA-1AHG153 (Panasonic) is the recommended substitute for new designs, as it maintains Active product status. The SEK153M010ST (CDE) remains the primary choice when available. Both components offer long-term manufacturer support and supply continuity.
