Substitute Part Grouping Explanation

Substitution of the EEU-EB2C101S is determined by the following criteria:

Electrical Equivalence: Capacitance value (100 µF) and tolerance (±20%) must remain constant. Voltage rating must equal or exceed 160 V.

Mechanical Compatibility: Lead spacing (7.50 mm) and mounting type (Through Hole, Radial) must match to ensure PCB footprint compatibility.

Thermal & Reliability: Lifetime rating and operating temperature range must support the application requirements.

Regulatory Compliance: All substitute parts must maintain ROHS3 and REACH compliance status.

Substitute parts are categorized as follows:

Upgrade Substitutes: Higher voltage rating (200 V) or extended lifetime (10000 Hrs) with identical or compatible mechanical dimensions.
Similar Substitutes: Matching electrical specifications with variations in physical dimensions, lead spacing, or lifetime ratings.

Engineering Selection Recommendations

Direct Mechanical Replacement (Identical PCB Footprint):

EEU-EB2D101S provides direct substitution with identical lead spacing (7.50 mm), diameter (18.00 mm), and height (22.00 mm). This part upgrades the voltage rating to 200 V while maintaining the same 5000-hour lifetime and ripple current specifications. All parts maintain ROHS3 compliance.

EEU-ED2C101S offers direct mechanical compatibility with identical lead spacing and diameter, with a reduced height of 20.00 mm. This part extends lifetime to 10000 hours at 105°C and increases ripple current capacity. MSL rating changes to 1 (Unlimited).

EEU-EE2C101S provides identical mechanical dimensions to the original part (7.50 mm lead spacing, 16.00 mm diameter, 22.00 mm height) with extended 10000-hour lifetime and increased ripple current performance (680 mA @ 120 Hz, 1.7 A @ 100 kHz).

Alternative Mechanical Configurations:

Parts with 5.00 mm lead spacing (EEU-ED2C101, EEU-ED2C101B, EEU-EE2C101) require PCB redesign due to different footprint requirements. These options provide extended lifetime (10000 hours) and are suitable only when board layout permits modification.

Compliance Status:

All substitute parts maintain Active product status and ROHS3/REACH compliance. Parts in the ED and EE series introduce MSL rating of 1 (Unlimited), indicating moisture sensitivity considerations for storage and handling.

Frequently Asked Questions (FAQ)

Q: Can EEU-EB2D101S replace EEU-EB2C101S without PCB modification?

A: Yes. Both parts share identical lead spacing (7.50 mm), diameter (18.00 mm), and height (22.00 mm). The higher voltage rating (200 V vs. 160 V) provides additional design margin with no mechanical impact.

Q: What is the difference between EEU-ED2C101S and EEU-EE2C101S?

A: Both parts offer 10000-hour lifetime and identical mechanical dimensions (7.50 mm lead spacing, 16.00 mm diameter, 22.00 mm height). EEU-EE2C101S provides higher ripple current capacity (680 mA @ 120 Hz vs. 576 mA) and belongs to the EE-A series. EEU-ED2C101S belongs to the ED-A series with MSL rating of 1 (Unlimited).

Q: Why do some substitute parts have different lead spacing?

A: Parts with 5.00 mm lead spacing (ED and EE series variants) represent different mechanical form factors. These require PCB footprint redesign and are not direct drop-in replacements. Selection depends on available board space and design flexibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 Compliant status and REACH Unaffected designation, matching the regulatory compliance of the original EEU-EB2C101S.

Q: What does MSL rating 1 (Unlimited) mean for ED and EE series parts?

A: MSL 1 indicates the component can be stored indefinitely at room temperature without moisture absorption concerns. This differs from the original part's "Not Applicable" MSL rating and does not affect electrical performance or substitution suitability.

Q: Can I use EEU-EB2C101 (without the "S" suffix) as a substitute?

A: EEU-EB2C101 shares electrical specifications but has different physical dimensions (16.00 mm diameter, 27.00 mm height vs. 18.00 mm diameter, 22.00 mm height). PCB footprint compatibility must be verified before selection.
