Tolerance: ±20% (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)
Lead Spacing: 0.295" (7.50 mm) (exact match required)
Polarization: Polar (exact match required)

Secondary Consideration Parameters:

Lifetime @ Temperature: 10,000 Hrs @ 105°C or greater
Operating Temperature Range: -25°C ~ 105°C (exact match required)
Physical Dimensions: Height and diameter must accommodate board layout constraints

Parts are grouped as direct equivalents when all primary parameters match exactly. Parts with extended lifetime ratings or equivalent ripple current specifications are listed as suitable alternatives. Parts with reduced lifetime ratings or different physical dimensions are noted for application-specific evaluation.

Engineering Selection Recommendations

Direct Equivalents (Identical Electrical and Mechanical Specifications):

EEU-ED2D101S is a direct equivalent with identical electrical ratings and matching physical dimensions. Both parts are Panasonic ED-A series, ROHS3 compliant, and active in production. The only difference is packaging format (Cut Tape versus Bulk).

Functionally Compatible Substitutes (Matching Electrical Specifications with Minor Dimension Variations):

EEU-ED2D101 matches all electrical parameters and lead spacing but has different physical dimensions (16.00 mm diameter, 25.00 mm height). This part is suitable for applications where board layout accommodates the larger height profile.

EEU-EE2D101S provides identical electrical performance and physical dimensions to the main part. It is Panasonic EE-A series, ROHS3 compliant, and active in production.

Reduced Lifetime Alternatives (Lower Thermal Endurance):

EEU-EB2D101S and EEU-EB2D101 are Panasonic EB-A series parts rated for 5,000 hours at 105°C, half the lifetime of the main part. These are suitable only for applications with lower thermal stress requirements.

ECA-2DHG101 is rated for 2,000 hours at 105°C and is suitable only for applications with minimal thermal cycling or short operational lifespans.

Extended Lifetime Alternative (Higher Thermal Endurance):

UCA2D101MHD6 is a Nichicon UCA series part rated for 12,000 hours at 105°C, exceeding the main part's 10,000-hour rating. However, this part is marked as Obsolete and should not be selected for new designs.

Mechanical Incompatibility:

UPT2D101MHD has different lead spacing (5.00 mm versus 7.50 mm) and different physical dimensions. This part is not mechanically compatible with the EEU-ED2D101SB footprint and requires board redesign.

Frequently Asked Questions (FAQ)

Q: Can EEU-ED2D101S replace EEU-ED2D101SB directly?

A: Yes. EEU-ED2D101S is a direct electrical equivalent with identical capacitance, voltage rating, tolerance, lifetime rating, and lead spacing. The only difference is packaging format. Both parts are interchangeable in the same circuit board layout.

Q: What is the difference between EEU-ED2D101SB and EEU-ED2D101?

A: Both parts are Panasonic ED-A series with identical electrical specifications and 10,000-hour lifetime ratings. The difference is physical dimensions: EEU-ED2D101SB has a diameter of 18.00 mm and height of 22.00 mm, while EEU-ED2D101 has a diameter of 16.00 mm and height of 25.00 mm. Lead spacing is identical at 7.50 mm. Selection depends on available board space.

Q: Can I use EEU-EB2D101S as a substitute?

A: EEU-EB2D101S has identical electrical specifications and physical dimensions to EEU-ED2D101SB but is rated for only 5,000 hours at 105°C compared to 10,000 hours. It is suitable only for applications with lower thermal stress or shorter operational lifespans.

Q: Why is UCA2D101MHD6 listed as an alternative if it is obsolete?

A: UCA2D101MHD6 is included for reference purposes only. It provides extended lifetime (12,000 hours at 105°C) and is electrically compatible, but its obsolete status makes it unsuitable for new designs. Existing inventory may be available through legacy component suppliers.

Q: Can UPT2D101MHD be used as a substitute?

A: No. UPT2D101MHD has different lead spacing (5.00 mm versus 7.50 mm) and different physical dimensions (12.50 mm diameter, 33.00 mm height). It is not mechanically compatible with the EEU-ED2D101SB footprint and cannot be used without board redesign.

Q: What does the "S" suffix mean in part numbers like EEU-ED2D101S?

A: The "S" suffix indicates a specific packaging or tape format variant. EEU-ED2D101S is supplied in Bulk packaging, while EEU-ED2D101SB is supplied in Cut Tape format. Electrical specifications are identical.

Q: Are all listed substitutes ROHS3 compliant?

A: Yes. All parts listed in this reference are ROHS3 compliant, meeting environmental and hazardous substance restrictions for electronic components.

Q: What is the ripple current rating for EEU-ED2D101SB?

A: The main part is rated for 576 mA at 120 Hz (low frequency) and 1.28 A at 100 kHz (high frequency). Substitute parts may have different ripple current ratings; refer to the Parameter Comparison table for specific values.
