ECE-T2AA682FA Equivalent & Substitute Parts

Part Overview

The ECE-T2AA682FA is a 6800 µF, 100 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components. This radial, can-style snap-in capacitor with 4 leads is designed for general-purpose applications requiring high capacitance and voltage ratings. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing system support, maintenance, and new design implementations where this specification remains applicable.

Substitute Part Grouping Explanation

Substitution of the ECE-T2AA682FA is determined by strict equivalence across the following critical parameters:

Capacitance value: 6800 µF (exact match required)
Voltage rating: 100 V (exact match required)
Tolerance: ±20% (exact match required)
ESR: 37 mOhm (exact match required)
Lifetime specification: 3000 Hrs @ 105°C (exact match required)
Operating temperature range: -40°C ~ 105°C (exact match required)
Package type: Radial, Can - Snap-In - 4 Lead (exact match required)
Mounting type: Through Hole (exact match required)
Physical dimensions: 1.575" Dia (40.00 mm) and height within tolerance (exact match required)

The substitute part 383LX682M100N052 from Cornell Dubilier Electronics meets all critical electrical and mechanical parameters. Minor variations in height (2.047" vs. 1.969") and ripple current specifications at different frequencies remain within acceptable engineering tolerances for general-purpose applications.

Engineering Selection Recommendations

The 383LX682M100N052 from Cornell Dubilier Electronics is a direct functional equivalent to the obsolete ECE-T2AA682FA. Selection of this substitute is supported by:

Identical electrical specifications across all critical parameters (capacitance, voltage, tolerance, ESR, lifetime, operating temperature)
Identical mechanical package configuration (Radial, Can - Snap-In - 4 Lead, Through Hole mounting)
Matching physical dimensions within acceptable tolerance (height difference of 0.078" / 2.00 mm)
Active product status ensuring ongoing availability and supply chain continuity
ROHS3 compliance and REACH unaffected status providing regulatory advantage over the original part

The substitute part is suitable for direct replacement in applications where the ECE-T2AA682FA specification is required.

Frequently Asked Questions (FAQ)

Q: Can the 383LX682M100N052 be used as a direct replacement for the ECE-T2AA682FA?

A: Yes. Both parts share identical capacitance (6800 µF), voltage rating (100 V), tolerance (±20%), ESR (37 mOhm), lifetime (3000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), and package configuration (Radial, Can - Snap-In - 4 Lead). The height difference of 0.078" (2.00 mm) is within acceptable mechanical tolerance for through-hole mounted components.

Q: What is the primary reason for substitution?

A: The ECE-T2AA682FA is classified as obsolete. The 383LX682M100N052 is an active product from Cornell Dubilier Electronics, ensuring availability and supply chain continuity.

Q: Are there compliance differences between the two parts?

A: Yes. The 383LX682M100N052 is ROHS3 compliant and REACH unaffected, providing regulatory advantages. The original ECE-T2AA682FA is REACH affected. Both parts carry EAR99 ECCN classification.

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

A: Substitution is determined by exact equivalence in capacitance, voltage rating, tolerance, ESR, lifetime specification, operating temperature range, package type, and mounting configuration. All these parameters are identical between the two parts.

Q: Are there any ripple current differences?

A: Minor differences exist in ripple current specifications at different frequencies. The ECE-T2AA682FA specifies 4.57 A @ 120 Hz and 5.256 A @ 10 kHz. The 383LX682M100N052 specifies 4.6 A @ 120 Hz and 5.3 A @ 20 kHz. These variations are within acceptable engineering tolerance for general-purpose applications.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
