ECO-S1KP682DA Equivalent & Substitute Parts

Part Overview

The ECO-S1KP682DA is a 6800 µF, 80 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Panasonic Electronic Components. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support and procurement planning. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 3000 hours at 85°C, serving general-purpose applications requiring high-capacitance energy storage.

Substitute Part Grouping Explanation

Substitution validity for the ECO-S1KP682DA is determined by strict equivalence across the following critical parameters:

Capacitance: 6800 µF (exact match required)
Voltage Rating: 80 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can - Snap-In (exact match required)
Lead Spacing: 10.00 mm (exact match required)
Operating Temperature Range: -40°C to 85°C (minimum requirement)
Lifetime Rating: 3000 Hrs @ 85°C (minimum requirement)

The three substitute parts identified below meet all critical electrical and mechanical parameters. Variations in ESR, ripple current ratings, and physical height are permissible within the constraints of the snap-in package form factor and do not affect functional interchangeability in general-purpose applications.

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the ECO-S1KP682DA based on electrical and mechanical parameters. Selection among the three Cornell Dubilier Electronics alternatives should be based on the following considerations:

380LX682M080K052: This part offers the lowest ESR at 45 mOhm and is ROHS3 compliant with active product status. It is suitable for applications where minimal series resistance is beneficial. The maximum seated height of 52.00 mm represents a 2 mm increase over the original part and must be verified against PCB layout constraints.

SLPX682M080H7P3: This part features a larger case diameter of 35.00 mm but a reduced height of 40.00 mm, making it suitable for space-constrained applications with vertical height limitations. It maintains ROHS3 compliance and active product status.

SLPX682M080E9P3: This part matches the original physical dimensions (30.00 mm diameter, 50.00 mm height) most closely while maintaining ROHS3 compliance and active product status. ESR is 49 mOhm, comparable to the SLPX682M080H7P3 variant.

All substitute parts carry REACH Unaffected or REACH Affected status and share the same ECCN (EAR99) and HTSUS (8532.22.0040) classifications as the original component.

Frequently Asked Questions (FAQ)

Q: Can the SLPX682M080H7P3 be used as a direct replacement despite its larger case diameter?

A: The SLPX682M080H7P3 has a case diameter of 35.00 mm compared to the original 30.00 mm. While all electrical parameters are equivalent, physical clearance on the PCB must be verified before substitution. The reduced height of 40.00 mm may provide layout advantages in some applications.

Q: What is the significance of the ESR differences among the substitute parts?

A: ESR variations (45 mOhm to 49 mOhm) are within acceptable ranges for general-purpose applications. The 380LX682M080K052 offers the lowest ESR, which may be advantageous in applications sensitive to ripple current dissipation. For most general-purpose circuits, these differences are not functionally significant.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts are ROHS3 compliant. The original ECO-S1KP682DA RoHS status was not specified in the available data.

Q: Does the height difference of the 380LX682M080K052 affect compatibility?

A: The 380LX682M080K052 has a maximum seated height of 52.00 mm versus 50.00 mm for the original part. This 2 mm difference must be evaluated against available vertical clearance on the PCB and within the enclosure to ensure mechanical fit.

Q: Why is the original part obsolete while the substitutes are active?

A: The ECO-S1KP682DA from Panasonic's TS-UP series has been discontinued. The Cornell Dubilier Electronics alternatives from the 380LX and SLPX series remain in active production, ensuring long-term availability for system support and new designs.
