Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 338KXM016M are identified based on strict electrical and mechanical parameter matching within the aluminum electrolytic capacitor category. The substitution logic is based on the following critical parameters:

Electrical Parameters (Non-Negotiable):

• Capacitance value: 3300 µF (exact match required)
• Voltage rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)

Mechanical Parameters (Non-Negotiable):

• Package type: Radial, Can (exact match required)
• Mounting type: Through Hole (exact match required)
• Lead spacing: 5.00 mm (exact match required)
• Diameter: 12.50 mm (exact match required)

Environmental & Compliance Parameters (Acceptable Variance):

• Operating temperature range: -55°C to 105°C (must encompass or match)
• Lifetime rating: May vary (5000 Hrs or greater acceptable)
• RoHS status: ROHS3 Compliant (required)

The substitute part ELXZ160ELL332MK35S meets all critical electrical and mechanical parameters, with acceptable variations in lifetime rating and additional automotive-grade certification.

Engineering Selection Recommendations

Primary Part: 338KXM016M

The 338KXM016M remains the primary selection for applications requiring general-purpose aluminum electrolytic capacitor functionality with the specified electrical and mechanical parameters. This part is active in production and ROHS3 compliant.

Substitute Part: ELXZ160ELL332MK35S

The ELXZ160ELL332MK35S is a direct functional equivalent suitable for substitution in applications where the 338KXM016M is unavailable. This substitute offers the following advantages:

• Identical electrical specifications (3300 µF, 16 V, ±20% tolerance)
• Identical mechanical compatibility (radial, through-hole, 5.00 mm lead spacing, 12.50 mm diameter)
• Extended lifetime rating (7000 Hrs @ 105°C versus 5000 Hrs)
• AEC-Q200 automotive-grade certification, indicating enhanced reliability screening
• Active product status with established supply chain

The 0.5 mm height variance (36.50 mm versus 37.00 mm) presents no functional or assembly incompatibility for through-hole mounting applications.

Both parts are ROHS3 compliant and suitable for equivalent circuit performance.

Frequently Asked Questions (FAQ)

Q: Can ELXZ160ELL332MK35S be used as a direct replacement for 338KXM016M on existing PCBs?

A: Yes. Both parts share identical lead spacing (5.00 mm), diameter (12.50 mm), and mounting type (through-hole radial). The 0.5 mm height difference (36.50 mm versus 37.00 mm) does not affect PCB compatibility or assembly clearance for standard through-hole applications.

Q: Are the electrical characteristics identical between these two parts?

A: The critical electrical parameters are identical: 3300 µF capacitance, 16 V voltage rating, and ±20% tolerance. Both parts operate across the same temperature range (-55°C to 105°C) and maintain polar polarity. The ELXZ160ELL332MK35S provides a longer lifetime rating (7000 Hrs @ 105°C versus 5000 Hrs), which represents an enhancement rather than a deviation.

Q: What is the significance of the AEC-Q200 rating on the substitute part?

A: AEC-Q200 is an automotive-grade qualification standard indicating that the ELXZ160ELL332MK35S has undergone enhanced reliability testing and screening. This certification does not affect general-purpose application compatibility but indicates a higher level of quality assurance suitable for demanding environments.

Q: Are both parts RoHS compliant?

A: Yes. Both the 338KXM016M and ELXZ160ELL332MK35S are ROHS3 compliant, meeting current regulatory requirements for hazardous substance restrictions.

Q: Can I use the substitute part in a circuit designed for the primary part without circuit modifications?

A: Yes. The substitute part maintains identical capacitance, voltage rating, tolerance, and polarity. No circuit modifications are required. The extended lifetime rating of the substitute part provides additional margin for thermal stress conditions.

Q: What is the difference in ESR and impedance between these parts?

A: The 338KXM016M specifies 80.4 mOhm ESR @ 120 Hz and 39 mOhms impedance. The ELXZ160ELL332MK35S specifies 22 mOhms impedance. The lower impedance of the substitute part indicates improved high-frequency performance characteristics, which is beneficial for ripple current handling and thermal stability.
