SEK682M025ST Equivalent & Substitute Parts

Part Overview

The SEK682M025ST is a 6800 µF, 25 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can package configuration. This component is designed for general-purpose applications requiring high capacitance values at moderate voltage ratings. The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and reliability ratings align with the original component, enabling direct replacement in circuit designs without functional compromise.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SEK682M025ST is determined by strict alignment of the following electrical and mechanical parameters:

Electrical Criteria:

• Capacitance value: 6800 µF (exact match required)
• Voltage rating: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Operating temperature range: -55°C to 105°C (exact match required)
• Lifetime specification: 2000 Hrs @ 105°C (exact match required)

Mechanical Criteria:

• Lead spacing: 0.295" (7.50mm) (exact match required)
• Diameter: 0.709" (18.00mm) (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial, Can (exact match required)

Compliance Criteria:

• RoHS3 compliance status (required)
• REACH unaffected status (required)

The ECA-1EHG682 manufactured by Panasonic Electronic Components satisfies all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the SEK682M025ST and ECA-1EHG682 are Active product status components with full RoHS3 compliance and REACH unaffected certification. Selection between these parts is based on availability, lead time, and inventory position rather than electrical or mechanical differentiation.

The ECA-1EHG682 exhibits a reduced seated height of 1.476" (37.50mm) compared to the SEK682M025ST at 1.654" (42.00mm), providing a 0.178" (4.50mm) dimensional advantage in space-constrained applications. This height differential does not affect electrical performance or circuit functionality and may provide layout optimization benefits in compact designs.

Both components satisfy identical electrical specifications, temperature operating ranges, and reliability ratings. The choice between manufacturers should be determined by procurement requirements, supply chain considerations, and design margin preferences.

Frequently Asked Questions (FAQ)

Q: Can the ECA-1EHG682 be used as a direct replacement for the SEK682M025ST?

A: Yes. Both components share identical capacitance (6800 µF), voltage rating (25 V), tolerance (±20%), operating temperature range (-55°C to 105°C), lifetime specification (2000 Hrs @ 105°C), lead spacing (0.295" / 7.50mm), and diameter (0.709" / 18.00mm). Both are RoHS3 compliant and REACH unaffected. The ECA-1EHG682 has a reduced height of 1.476" (37.50mm) versus 1.654" (42.00mm), which does not compromise electrical performance.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by exact matching of capacitance value, voltage rating, tolerance, operating temperature range, lifetime specification, lead spacing, diameter, mounting type, and package configuration. Compliance certifications (RoHS3 and REACH status) must also align.

Q: Does the height difference between these parts affect circuit performance?

A: No. The height difference of 0.178" (4.50mm) is a mechanical dimension only and does not affect electrical characteristics, capacitance, voltage rating, or reliability. The reduced height of the ECA-1EHG682 may provide layout advantages in space-constrained applications.

Q: Are both parts suitable for the same temperature operating range?

A: Yes. Both the SEK682M025ST and ECA-1EHG682 operate across the identical temperature range of -55°C to 105°C with a rated lifetime of 2000 hours at 105°C.

Q: What is the lead spacing for these components?

A: Both components have a lead spacing of 0.295" (7.50mm), ensuring compatibility with standard through-hole PCB layouts designed for either part.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both components are RoHS3 compliant and REACH unaffected, meeting identical regulatory and environmental standards.
