Substitute Part Grouping Explanation

Substitution eligibility for the EEE-TK2A331AM is determined by strict equivalence across the following critical parameters:

Electrical equivalence requires identical capacitance (330 µF), voltage rating (100 V), and tolerance (±20%). The ESR specification of 280 mOhm @ 100 kHz and ripple current ratings (300 mA @ 120 Hz, 400 mA @ 100 kHz) establish performance boundaries for signal integrity and thermal management.

Mechanical equivalence requires identical package classification (Radial, Can - SMD), physical dimensions (0.709" diameter, 0.650" maximum height), and surface mount land size (0.748" L x 0.748" W). These parameters ensure PCB layout compatibility and assembly process alignment.

Environmental and compliance equivalence requires ROHS3 compliance and MSL 1 rating to maintain regulatory and manufacturing process compatibility.

The substitute part EEV-TG2A331M meets all electrical and mechanical equivalence criteria while introducing automotive-grade qualification (AEC-Q200) and modified ripple current performance at low frequency (260 mA @ 120 Hz versus 300 mA @ 120 Hz).

Parameter Comparison

Engineering Selection Recommendations

Both EEE-TK2A331AM and EEV-TG2A331M are Active status products manufactured by Panasonic Electronic Components with ROHS3 compliance and MSL 1 rating. Both parts satisfy the core electrical and mechanical requirements for 330 µF, 100 V aluminum electrolytic capacitor applications in surface mount configurations.

The EEV-TG2A331M substitute introduces AEC-Q200 automotive qualification, positioning it for applications requiring automotive-grade component certification. The ripple current specification at low frequency (120 Hz) is reduced from 300 mA to 260 mA in the substitute part; this parameter difference must be evaluated against specific circuit ripple current demands at low frequency operating conditions.

Selection between these parts depends on application requirements: general purpose applications may utilize either part based on availability and cost considerations, while automotive applications requiring AEC-Q200 qualification mandate the EEV-TG2A331M.

Frequently Asked Questions (FAQ)

Q: Can EEV-TG2A331M replace EEE-TK2A331AM in all applications?

A: Electrical and mechanical compatibility is established across capacitance, voltage rating, tolerance, ESR, operating temperature range, package dimensions, and mounting specifications. The ripple current at 120 Hz differs (260 mA versus 300 mA); circuit designs operating at or near the 300 mA specification require evaluation of the reduced 260 mA rating in the substitute part.

Q: What is the significance of the AEC-Q200 rating on EEV-TG2A331M?

A: AEC-Q200 is an automotive industry qualification standard. This rating indicates the EEV-TG2A331M meets automotive reliability and quality requirements. General purpose applications do not require this certification; automotive applications may mandate it depending on end-use classification.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both parts share identical package classification (Radial, Can - SMD), diameter (0.709" / 18.00 mm), maximum seated height (0.650" / 16.50 mm), and surface mount land size (0.748" L x 0.748" W / 19.00 mm x 19.00 mm). PCB layout and assembly tooling compatibility is maintained.

Q: What does MSL 1 (Unlimited) mean for storage and handling?

A: MSL 1 rating indicates unlimited shelf life under standard storage conditions. No moisture bake-out procedures are required prior to assembly, and no time-to-assembly restrictions apply after package opening.

Q: How do the ripple current specifications affect component selection?

A: Ripple current ratings define the maximum AC current the capacitor can handle at specified frequencies without exceeding thermal limits. The EEE-TK2A331AM supports 300 mA @ 120 Hz and 400 mA @ 100 kHz. The EEV-TG2A331M supports 260 mA @ 120 Hz and 400 mA @ 100 kHz. Circuit designs must ensure actual ripple current does not exceed the applicable rating for the selected part.
