Substitute Part Grouping Explanation

Substitution eligibility for the EEE-TG2A331M is determined by strict equivalence across the following parameters:

Capacitance value: 330 µF (exact match required)
Voltage rating: 100 V (exact match required)
Tolerance: ±20% (exact match required)
ESR @ 100 kHz: 280 mOhm (exact match required)
Lifetime @ 125°C: 2000 Hrs (exact match required)
Operating temperature range: -40°C ~ 125°C (exact match required)
Package type: Radial, Can - SMD (exact match required)
Physical dimensions: 18.00 mm Dia × 16.50 mm Height (exact match required)
Land size: 19.00 mm × 19.00 mm (exact match required)
Mounting type: Surface Mount (exact match required)
Polarization: Polar (exact match required)
MSL rating: 1 (Unlimited) (exact match required)

Two substitute parts meet these criteria:

EEE-TK2A331AM - Direct manufacturer equivalent with identical electrical and mechanical specifications. Differs in series designation (TK vs. TG), packaging format (Tape & Reel), and application classification (General Purpose vs. Automotive).
EEV-TG2A331M - Parametric equivalent maintaining identical electrical and mechanical specifications. Retains same series designation (TG) and automotive application rating. Differs in packaging format (Tape & Reel) and product line designation (EEV vs. EEE).

Engineering Selection Recommendations

Both substitute parts provide electrical and mechanical equivalence to the obsolete EEE-TG2A331M. Selection between them depends on application requirements and compliance mandates:

EEV-TG2A331M is the preferred substitute for automotive applications. It maintains the same series designation (TG), retains AEC-Q200 automotive qualification, and preserves the original application classification. Both parts are active products with confirmed RoHS3 and REACH compliance.

EEE-TK2A331AM provides an alternative for general-purpose applications where automotive qualification is not required. It offers identical electrical performance and mechanical compatibility but is classified for general-purpose use rather than automotive applications.

Both substitutes are available in Tape & Reel packaging format and are currently in active production status, ensuring supply continuity beyond the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can EEE-TK2A331AM be used in automotive applications originally designed for EEE-TG2A331M?

A: EEE-TK2A331AM meets all electrical and mechanical specifications of the original part. However, it is classified for general-purpose applications rather than automotive. Applications requiring AEC-Q200 certification should use EEV-TG2A331M instead.

Q: What is the difference between EEE-TK2A331AM and EEV-TG2A331M?

A: Both parts are parametric equivalents with identical capacitance, voltage, ESR, lifetime, and physical dimensions. EEV-TG2A331M retains the TG series designation and automotive application rating. EEE-TK2A331AM uses the TK series designation and is classified for general-purpose use. For automotive designs, EEV-TG2A331M is the direct equivalent.

Q: Are the substitute parts available in the same packaging as the original EEE-TG2A331M?

A: The substitute parts are supplied in Tape & Reel (TR) packaging format. The original part packaging format was not specified in the technical data. Both substitutes maintain identical surface mount land size (19.00 mm × 19.00 mm) and physical dimensions (18.00 mm Dia × 16.50 mm Height), ensuring PCB compatibility.

Q: Do the substitute parts have the same moisture sensitivity level?

A: Yes. Both EEE-TK2A331AM and EEV-TG2A331M carry MSL rating 1 (Unlimited), identical to the original EEE-TG2A331M.

Q: Are the substitute parts RoHS and REACH compliant?

A: Yes. Both substitute parts are ROHS3 Compliant and REACH Unaffected. The original part's compliance status was not specified.
