SEK682M010ST Equivalent & Substitute Parts Reference

Part Overview

The SEK682M010ST is a 6800 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 requiring high capacitance values in compact through-hole configurations. The part operates across a temperature range of -55°C to 105°C with a rated lifetime of 2000 hours at 105°C.

Substitute parts become necessary when the primary manufacturer experiences supply constraints, when design requirements demand extended operational lifetime, or when alternative sourcing strategies are implemented to optimize procurement and inventory management.

Substitute Part Grouping Explanation

Substitution logic for the SEK682M010ST is based on strict electrical and mechanical parameter matching. All substitute parts must satisfy the following mandatory criteria:

Electrical Parameters (Non-Negotiable):

• Capacitance: 6800 µF (exact match)
• Voltage Rating: 10 V (exact match)
• Tolerance: ±20% (exact match)
• Polarization: Polar (exact match)
• Operating Temperature Range: -55°C to 105°C (minimum requirement)

Mechanical Parameters (Non-Negotiable):

• Package Type: Radial, Can (exact match)
• Mounting Type: Through Hole (exact match)
• Lead Spacing: 0.295" (7.50mm) (exact match)
• Diameter: 0.630" (16.00mm) (exact match)

Regulatory Compliance (Non-Negotiable):

• RoHS Status: ROHS3 Compliant (exact match)
• REACH Status: REACH Unaffected (exact match)

Secondary Parameters (Allowable Variation):

• Height: Variation permitted within physical board space constraints
• Lifetime @ 105°C: Equal or greater than 2000 hours
• ESR and Ripple Current: Variation permitted based on application requirements
• Product Status: Active preferred; Not For New Designs acceptable for replacement scenarios

The two identified substitute parts (ECA-1AHG682 and UPW1A682MHD) satisfy all mandatory criteria and represent valid alternatives to the SEK682M010ST.

Parameter Comparison

Engineering Selection Recommendations

ECA-1AHG682 (Panasonic Electronic Components):

The ECA-1AHG682 is classified as Active product status and represents a direct functional equivalent to the SEK682M010ST. This part maintains identical electrical specifications (6800 µF, 10 V, ±20% tolerance) and mechanical dimensions (0.630" diameter, 0.295" lead spacing). The height is reduced to 1.063" (27.00mm) compared to the SEK682M010ST at 1.260" (32.00mm), providing potential space optimization benefits in compact board layouts. Both parts comply with ROHS3 and REACH requirements. The ECA-1AHG682 is suitable for new designs and ongoing production applications.

UPW1A682MHD (Nichicon):

The UPW1A682MHD satisfies all mandatory electrical and mechanical substitution criteria. This part is classified as Not For New Designs, indicating it is intended for replacement and legacy system support rather than new product development. The UPW1A682MHD offers extended operational lifetime of 8000 hours at 105°C compared to 2000 hours for the SEK682M010ST, making it suitable for applications requiring enhanced reliability and extended service life. The height is 1.240" (31.50mm), which is compatible with most board space allocations. ROHS3 and REACH compliance are confirmed. This part is appropriate for retrofit, repair, and maintenance scenarios where extended lifetime is beneficial.

Selection Criteria:

For new designs and standard production applications, the ECA-1AHG682 is the preferred substitute due to Active product status and ongoing manufacturer support. For applications requiring extended operational lifetime or for replacement of existing SEK682M010ST units in field service, the UPW1A682MHD provides superior reliability characteristics. Both parts are electrically and mechanically interchangeable with the SEK682M010ST within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the ECA-1AHG682 be used as a direct replacement for the SEK682M010ST in existing designs?

A: Yes. The ECA-1AHG682 matches all critical electrical parameters (6800 µF, 10 V, ±20% tolerance), mechanical dimensions (0.630" diameter, 0.295" lead spacing), and regulatory compliance (ROHS3, REACH). The reduced height of 1.063" (27.00mm) versus 1.260" (32.00mm) provides additional board space clearance. No circuit modifications are required.

Q: What is the difference between the ECA-1AHG682 and UPW1A682MHD?

A: Both parts are electrically and mechanically equivalent to the SEK682M010ST. The primary differences are: (1) Product Status—ECA-1AHG682 is Active; UPW1A682MHD is Not For New Designs; (2) Lifetime—ECA-1AHG682 provides 2000 hours at 105°C; UPW1A682MHD provides 8000 hours at 105°C; (3) Height—ECA-1AHG682 is 1.063" (27.00mm); UPW1A682MHD is 1.240" (31.50mm). The UPW1A682MHD is suitable for replacement applications requiring extended reliability.

Q: Are there any height restrictions when substituting these parts?

A: The SEK682M010ST has a maximum seated height of 1.260" (32.00mm). The ECA-1AHG682 at 1.063" (27.00mm) and UPW1A682MHD at 1.240" (31.50mm) are both shorter and will fit within the same board space. If the PCB layout includes height-sensitive components or enclosure constraints, verify that the reduced height does not create clearance issues with adjacent components or mechanical structures.

Q: Do these substitute parts require any circuit design changes?

A: No. All three parts (SEK682M010ST, ECA-1AHG682, UPW1A682MHD) are pin-compatible through-hole radial capacitors with identical lead spacing (0.295" / 7.50mm) and diameter (0.630" / 16.00mm). They are electrically equivalent with matching capacitance, voltage rating, and tolerance specifications. Direct PCB footprint compatibility is confirmed.

Q: Which substitute part should be selected for new product designs?

A: The ECA-1AHG682 is the recommended choice for new designs due to its Active product status, indicating ongoing manufacturer support and availability. This part provides equivalent performance to the SEK682M010ST with the added benefit of reduced height for potential space optimization.

Q: Can the UPW1A682MHD be used in new designs?

A: The UPW1A682MHD is classified as Not For New Designs. This designation indicates the manufacturer does not recommend this part for new product development. However, it remains suitable for replacement, repair, and legacy system applications where extended lifetime (8000 hours at 105°C) provides additional reliability benefits.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. The SEK682M010ST, ECA-1AHG682, and UPW1A682MHD are all ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components in regulated markets.
