EEU-FC2A680 Equivalent & Substitute Parts

Part Overview

The EEU-FC2A680 is a 68 µF, 100 V aluminum electrolytic capacitor in radial, can package manufactured by Panasonic Electronic Components. This part is rated for 5000 hours at 105°C and meets AEC-Q200 automotive qualification standards. The component is currently in active production status with 1249 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life, experiences supply constraints, or when design requirements allow for alternative manufacturers while maintaining electrical and mechanical compatibility. The substitute parts listed below maintain the core electrical specifications (68 µF capacitance, 100 V rated voltage, ±20% tolerance) and mechanical form factor (radial, through-hole mounting) required for direct replacement.

Substitute Part Grouping Explanation

Substitution eligibility for the EEU-FC2A680 is determined by the following mandatory parameters:

Capacitance: 68 µF (exact match required)
Voltage Rating: 100 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)

Package Type: Radial, Can (exact match required)
Operating Temperature Range: -55°C to 105°C (exact match required)

All substitute parts listed below meet these mandatory criteria. Secondary parameters such as lifetime rating, ripple current specifications, impedance, physical dimensions (diameter and height), product status, and manufacturer certifications are provided for engineering evaluation but do not disqualify a part from substitution eligibility.

Engineering Selection Recommendations

Primary Selection (Active Status)

EEU-FC2A680L and EEU-FC2A680LB are both Panasonic parts in active production status. These parts are electrically equivalent to the main part and suitable for new designs. EEU-FC2A680LB offers higher inventory availability (1738 units) and is packaged in Cut Tape format. Both parts feature reduced lifetime ratings (3000 hours at 105°C versus 5000 hours) and different physical dimensions, which must be verified for PCB layout compatibility.

Secondary Selection (Automotive Compliance)

UPM2A680MHD6 and UPM2A680MPD are Nichicon parts that maintain AEC-Q200 automotive qualification. Both are rated for 5000 hours at 105°C, matching the lifetime specification of the main part. These parts carry "Not For New Designs" status, indicating they are available for legacy system support and replacement applications only.

Tertiary Selection (General Purpose)

UPJ2A680MHD6 and UPW2A680MPD are Nichicon parts without automotive ratings. UPJ2A680MHD6 is marked "Not For New Designs" and lacks AEC-Q200 certification. UPW2A680MPD similarly carries "Not For New Designs" status and is rated for general purpose applications. These parts are suitable only for non-automotive replacement scenarios where automotive qualification is not required.

Compliance Considerations

All listed parts are ROHS3 compliant. UPM2A680MHD6 and UPM2A680MPD are REACH Affected; UPM2A680MPD specifically indicates REACH Affected status. The main part EEU-FC2A680 and Panasonic alternatives EEU-FC2A680L and EEU-FC2A680LB are REACH Unaffected. For applications subject to REACH regulations, Panasonic parts are preferred.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC2A680L be used as a direct replacement for EEU-FC2A680?

A: EEU-FC2A680L is electrically compatible (same capacitance, voltage, tolerance, and operating temperature range). However, it has a reduced lifetime rating (3000 hours versus 5000 hours at 105°C) and different physical dimensions (10.00 mm diameter, 25.00 mm height versus 12.50 mm diameter, 16.00 mm height). PCB layout must be verified to accommodate the taller form factor.

Q: What is the difference between EEU-FC2A680L and EEU-FC2A680LB?

A: Both parts are electrically identical with 68 µF capacitance, 100 V rating, and 3000-hour lifetime at 105°C. The primary differences are packaging format (EEU-FC2A680L is Bulk; EEU-FC2A680LB is Cut Tape) and physical height (25.00 mm versus 27.00 mm). EEU-FC2A680LB has higher inventory availability.

Q: Are Nichicon UPM series parts suitable for automotive applications?

A: UPM2A680MHD6 and UPM2A680MPD both carry AEC-Q200 automotive qualification and are suitable for automotive applications. However, both are marked "Not For New Designs," indicating they are available for legacy and replacement applications only. For new automotive designs, Panasonic EEU-FC series parts in active status are recommended.

Q: What is the significance of "Not For New Designs" status?

A: Parts marked "Not For New Designs" are available for existing product support and replacement applications but should not be selected for new circuit designs. These parts may have limited future availability or are being phased out by the manufacturer. For new designs, parts with "Active" status are preferred.

Q: How do physical dimensions affect substitution?

A: All substitute parts maintain the same lead spacing (5.00 mm), which ensures PCB footprint compatibility. However, diameter and height vary. Designs with tight vertical or horizontal clearance constraints must verify that the substitute part's physical dimensions fit within the available PCB space. Panasonic EEU-FC2A680L and EEU-FC2A680LB have smaller diameters (10.00 mm) but greater heights (25.00 mm and 27.00 mm respectively) compared to the main part (12.50 mm diameter, 16.00 mm height).

Q: What is the impact of REACH Affected status?

A: Parts marked REACH Affected are subject to European REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. For applications requiring REACH compliance or operating in regulated markets, REACH Unaffected parts (EEU-FC2A680, EEU-FC2A680L, EEU-FC2A680LB, UPJ2A680MHD6, UPW2A680MPD) are preferred. UPM2A680MHD6 and UPM2A680MPD are REACH Affected and require additional compliance verification.

Q: Can I use a part with lower lifetime rating as a substitute?

A: Substitution with lower lifetime ratings is permissible only if the application's thermal and operational profile does not require the higher 5000-hour rating. EEU-FC2A680L and EEU-FC2A680LB are rated for 3000 hours at 105°C. Applications requiring extended service life at elevated temperatures should retain the 5000-hour rated parts (EEU-FC2A680, UPJ2A680MHD6, UPM2A680MHD6, UPM2A680MPD, or UPW2A680MPD).
