Substitute Part Grouping Explanation

Substitution of the EKMG161ELL331MMP1S is determined by the following critical parameters: capacitance value (330 µF), voltage rating (160 V or higher), tolerance (±20%), polarization (polar), mounting type (through hole), and physical form factor (radial can with 0.295" lead spacing and 0.709" diameter). Parts are grouped into three categories based on substitution suitability:

Parametric Equivalent: Parts with identical electrical specifications (330 µF, 160 V, ±20%, 2000 Hrs @ 105°C) and matching physical dimensions. These provide direct replacement capability.

Similar/Upgraded: Parts with identical capacitance and voltage rating but enhanced lifetime ratings (10000 Hrs or 12000 Hrs @ 105°C) or higher voltage ratings (220 V). These offer improved performance while maintaining electrical compatibility.

Cross-Manufacturer Equivalent: Parts from alternative manufacturers (Nichicon, Cornell Dubilier Electronics) meeting the same electrical and mechanical specifications, providing supply chain flexibility.

Engineering Selection Recommendations

Direct Replacement (Parametric Equivalent)

The EKMQ161ELL331MMP1S is the primary direct replacement for the obsolete EKMG161ELL331MMP1S. Both parts are manufactured by Chemi-Con, share identical electrical specifications (330 µF, 160 V, ±20%, 2000 Hrs @ 105°C), and maintain the same physical footprint (18.00 mm diameter, 37.00 mm height, 7.50 mm lead spacing). The EKMQ161ELL331MMP1S is currently active in production and ROHS3 compliant.

Enhanced Performance Substitutes (Same Voltage Rating)

The EKXG161ELL331MMN3S offers a five-fold improvement in lifetime rating (10000 Hrs @ 105°C) while maintaining identical electrical specifications and lead spacing. Physical height is reduced to 31.50 mm, providing a more compact form factor. This part is suitable for applications where extended operational life is beneficial.

The UCY2C331MHD6 (Nichicon) provides a six-fold lifetime improvement (12000 Hrs @ 105°C) with identical electrical parameters. Height is reduced to 26.50 mm, and the can diameter remains 18.00 mm. This part is active and ROHS3 compliant.

Higher Voltage Substitute (Upgraded Rating)

The EKXJ221ELL331MMP1S is rated at 220 V (versus 160 V) with the same 330 µF capacitance and ±20% tolerance. It provides a 12000-hour lifetime rating and maintains identical physical dimensions to the original part. This upgrade is suitable for applications requiring higher voltage margin or improved reliability.

Cross-Manufacturer Alternatives

The SEK331M160ST (Cornell Dubilier Electronics) matches the original part's electrical specifications exactly (330 µF, 160 V, ±20%, 2000 Hrs @ 105°C) with identical lead spacing. Height is 42.00 mm. This part is active and ROHS3 compliant, providing supply chain diversity.

The UCY2C331MHD (Nichicon) delivers 12000-hour lifetime with identical electrical ratings. The can diameter is reduced to 16.00 mm with height of 33.00 mm, offering a more compact footprint while maintaining 7.50 mm lead spacing.

Not Recommended for New Designs

The UVZ2C331MHD (Nichicon) is marked "Not For New Designs" and should not be selected for new applications despite meeting electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can the EKMQ161ELL331MMP1S directly replace the obsolete EKMG161ELL331MMP1S?

A: Yes. The EKMQ161ELL331MMP1S is a parametric equivalent with identical capacitance (330 µF), voltage rating (160 V), tolerance (±20%), lifetime (2000 Hrs @ 105°C), and physical dimensions (18.00 mm diameter, 37.00 mm height, 7.50 mm lead spacing). Both are through-hole radial cans with polar orientation.

Q: What is the difference between the EKXG161ELL331MMN3S and the original EKMG161ELL331MMP1S?

A: The EKXG161ELL331MMN3S maintains identical electrical specifications but extends the lifetime from 2000 hours to 10000 hours at 105°C. The physical height is reduced from 37.00 mm to 31.50 mm. All other parameters, including capacitance, voltage, tolerance, lead spacing, and can diameter, remain unchanged.

Q: Can I use the EKXJ221ELL331MMP1S as a substitute?

A: Yes, with the understanding that this part has a higher voltage rating (220 V versus 160 V). The capacitance remains 330 µF with ±20% tolerance. The higher voltage rating provides additional safety margin in the circuit. Physical dimensions and lead spacing are identical to the original part.

Q: Are there differences in physical size among the substitute parts?

A: Yes. While all parts maintain the 0.295" (7.50 mm) lead spacing and 0.709" (18.00 mm) can diameter (except UCY2C331MHD at 16.00 mm), heights vary: the original is 37.00 mm, EKXG161ELL331MMN3S is 31.50 mm, UCY2C331MHD6 is 26.50 mm, and SEK331M160ST is 42.00 mm. Verify PCB layout clearance before selection.

Q: Which substitute offers the best reliability for long-term operation?

A: The EKXJ221ELL331MMP1S and UCY2C331MHD6 both provide 12000-hour lifetime ratings at 105°C, representing a six-fold improvement over the original 2000-hour specification. The EKXG161ELL331MMN3S provides a five-fold improvement with 10000 hours.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All recommended substitute parts are ROHS3 compliant. The UVZ2C331MHD is also ROHS3 compliant but is marked "Not For New Designs" and should be avoided.

Q: Can I use a cross-manufacturer part like the Nichicon UCY2C331MHD?

A: Yes. The UCY2C331MHD meets the same electrical specifications (330 µF, 160 V, ±20%) and is ROHS3 compliant. It provides 12000-hour lifetime and maintains the required 7.50 mm lead spacing. The can diameter is 16.00 mm (versus 18.00 mm), so verify PCB footprint compatibility.

Q: What is the significance of the "Active" product status?

A: Parts marked "Active" are currently in production and available for procurement. The original EKMG161ELL331MMP1S is obsolete, making active substitutes necessary for new designs and ongoing production.
