LP682M035C7P3 Equivalent & Substitute Parts Reference

Part Overview

The LP682M035C7P3 is a 6800 µF, 35 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in a radial, can snap-in package. This component is classified as Active product status and is designed for general purpose applications requiring high capacitance values at moderate voltage ratings. The part features a 1000-hour lifetime rating at 105°C with an ESR of 61 mOhm at 120 Hz.

Substitute parts become necessary when the original component experiences extended lead times, inventory constraints, or when design flexibility permits selection from qualified alternatives that maintain electrical and mechanical compatibility within specified tolerance ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP682M035C7P3 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters (Must Match):

• Capacitance: 6800 µF (±20% tolerance band)
• Voltage Rating: 35 V (minimum)
• Polarization: Polar
• Mounting Type: Through Hole
• Package Type: Radial, Can - Snap-In
• Lead Spacing: 0.394" (10.00 mm)
• Operating Temperature Range: -40°C to 105°C (minimum)
• RoHS Compliance: ROHS3 Compliant

Allowable Variation Parameters:

• ESR (Equivalent Series Resistance): May vary based on manufacturer design
• Lifetime @ Temperature: May exceed minimum specification
• Physical Dimensions (Diameter, Height): Variation permitted within mechanical envelope constraints
• Ripple Current Ratings: May exceed minimum specification

All three substitute parts meet these criteria and are qualified for direct substitution in applications where the LP682M035C7P3 is specified.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain Active product status and full ROHS3 compliance, qualifying them for direct substitution in applications where the LP682M035C7P3 is specified.

SLP682M035A7P3 (Cornell Dubilier Electronics): This substitute offers extended lifetime (3000 hours at 105°C versus 1000 hours) with identical lead spacing and height. Physical diameter is reduced to 0.866" (22.00 mm), providing a smaller footprint. ESR increases to 78 mOhm. This part is suitable for applications where reduced physical envelope is acceptable and extended operational life is beneficial.

SLP682M035E1P3 (Cornell Dubilier Electronics): This substitute provides the highest ripple current capability (3.48 A at 20 kHz) and extended lifetime (3000 hours at 105°C). Physical dimensions increase to 1.181" diameter and 0.984" height. ESR is 78 mOhm at 120 Hz. This part is suitable for high-ripple-current applications where the larger envelope can be accommodated.

35MXG6800MEFCSN25X30 (Rubycon): This substitute maintains identical diameter (0.984" / 25.00 mm) to the main part with extended lifetime (3000 hours at 105°C). Height is reduced to 1.260" (32.00 mm). ESR specification is not provided. This part is suitable for applications where dimensional consistency with the original part is prioritized.

Selection among these substitutes depends on specific application requirements regarding physical envelope constraints, ripple current demands, and operational lifetime expectations.

Frequently Asked Questions (FAQ)

Q: Can SLP682M035A7P3 be used as a direct replacement for LP682M035C7P3?

A: SLP682M035A7P3 qualifies as a direct substitute based on matching capacitance (6800 µF), voltage rating (35 V), tolerance (±20%), operating temperature range (-40°C to 105°C), lead spacing (10.00 mm), and snap-in package type. The reduced diameter (22.00 mm versus 25.00 mm) must be verified against PCB layout constraints. Extended lifetime (3000 hours at 105°C) exceeds the original specification.

Q: What is the primary difference between SLP682M035E1P3 and the main part LP682M035C7P3?

A: Both parts share identical capacitance, voltage rating, tolerance, and lead spacing. SLP682M035E1P3 differs in physical dimensions (1.181" diameter and 0.984" height versus 0.984" diameter and 1.575" height), extended lifetime (3000 hours versus 1000 hours), and higher ripple current ratings. PCB layout compatibility must be confirmed before substitution.

Q: Is the Rubycon 35MXG6800MEFCSN25X30 compatible with the original LP682M035C7P3 footprint?

A: The Rubycon part maintains the same diameter (25.00 mm) and lead spacing (10.00 mm) as the original. Height is reduced from 1.575" to 1.260", which is compatible with most PCB layouts designed for the original part. Mechanical clearance verification is recommended.

Q: Can these substitutes be used interchangeably in the same circuit?

A: All three substitutes meet the critical electrical parameters (capacitance, voltage, tolerance, temperature range, polarization) and mechanical parameters (lead spacing, snap-in package, through-hole mounting). Interchangeability is confirmed for electrical function. Physical envelope differences require individual PCB layout verification.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts maintain ROHS3 compliance, MSL rating of 1 (Unlimited), REACH Unaffected status, and EAR99 ECCN classification, matching the original LP682M035C7P3 specifications.

Q: How does ESR variation affect circuit performance?

A: The main part specifies 61 mOhm ESR at 120 Hz. Substitute parts SLP682M035A7P3 and SLP682M035E1P3 specify 78 mOhm ESR. This 17 mOhm increase remains within acceptable tolerance for general purpose applications. The Rubycon part does not specify ESR. Applications with strict ESR requirements should reference detailed datasheets.

Q: Are there inventory considerations for these substitutes?

A: Current inventory levels are: LP682M035C7P3 (700 pcs), SLP682M035A7P3 (2934 pcs), SLP682M035E1P3 (3531 pcs), and 35MXG6800MEFCSN25X30 (1276 pcs). Substitute parts offer significantly higher availability.
