Substitute Part Grouping Explanation

Substitution of the EKY-160ELL331MHB5D is determined by the following critical parameters: capacitance (330 µF), tolerance (±20%), voltage rating, physical dimensions (0.315" diameter, 0.512" height, 3.50mm lead spacing), and mounting type (through hole radial can). Parts are grouped into three categories:

Upgrade Substitutes maintain or exceed the original specifications while offering improved performance characteristics such as higher voltage ratings (25 V) or extended lifetime ratings. These parts are pin-compatible and occupy identical PCB footprints.

Similar Substitutes match the original voltage rating (16 V) and capacitance but may differ in lifetime ratings or impedance characteristics. These parts maintain full mechanical and electrical compatibility.

Direct Substitutes from alternative manufacturers provide equivalent electrical and mechanical specifications with identical or superior performance metrics.

Engineering Selection Recommendations

For Direct Replacement (Same Voltage Rating): Select EKZE160ELL331MHB5D (Chemi-Con) or EEU-FM1C331 (Panasonic) when maintaining 16 V operation is required. Both parts are ROHS3 compliant and active products. Note that EKZE160ELL331MHB5D offers reduced lifetime (3000 Hrs vs. 7000 Hrs), while EEU-FM1C331 provides improved impedance performance (56 mOhms vs. 130 mOhms).

For Upgraded Performance: Select EKYB250ELL331MHB5D, EKZM250ELL331MHB5D, or 25ZLJ330M8X11.5 when circuit design permits 25 V operation. These parts offer superior impedance characteristics and extended lifetime ratings. EKZM250ELL331MHB5D and 25ZLH330MEFC8X11.5 provide the lowest impedance (56 mOhms) and extended 8000-hour lifetime. 25ZLJ330M8X11.5 offers the highest lifetime rating (9000 Hrs) with substantial inventory availability.

For Maximum Reliability: ESL337M025AGMAA (KEMET) provides the longest lifetime (10000 Hrs @ 105°C) and lowest ESR (61 mOhms @ 100kHz) among all substitutes. All recommended parts are ROHS3 compliant and REACH unaffected.

Avoid: UHE1C331MPD is marked "Not For New Designs" and should not be selected for new applications. EEU-FM1C331B has non-standard lead spacing (0.197" vs. 0.138") and requires PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can I use a 25 V rated capacitor in place of the 16 V original? A: Yes. A higher voltage rating provides design margin and is electrically compatible. The 25 V substitutes (EKYB250ELL331MHB5D, EKZM250ELL331MHB5D, 25YXJ330M8X11.5, 25ZLH330MEFC8X11.5, 25ZLJ330M8X11.5, ESL337M025AGMAA) maintain identical physical dimensions and lead spacing, requiring no PCB modifications.

Q: What is the impact of different impedance values? A: Lower impedance (56-75 mOhms) reduces voltage ripple and heat generation, improving performance in high-frequency applications. The original part has 130 mOhms impedance. Most active substitutes offer 56-87 mOhms, providing performance improvement.

Q: Does lifetime rating affect substitution compatibility? A: Lifetime rating indicates expected operational hours at 105°C. Lower lifetime (3000 Hrs) does not prevent substitution but may reduce component reliability in long-term applications. The original 7000-hour rating is matched by EKYB250ELL331MHB5D and 25YXJ330M8X11.5, while extended ratings (8000-10000 Hrs) are available in upgraded options.

Q: Are there lead spacing considerations? A: Standard lead spacing is 0.138" (3.50mm). EEU-FM1C331B uses 0.197" (5.00mm) spacing and requires PCB redesign. All other substitutes use standard 0.138" spacing and are direct drop-in replacements.

Q: Which substitute offers the best overall performance? A: 25ZLJ330M8X11.5 (Rubycon) combines 9000-hour lifetime, 75 mOhms impedance, standard lead spacing, and the highest inventory availability (75,891 pcs). ESL337M025AGMAA (KEMET) offers superior ESR specification (61 mOhms @ 100kHz) and 10000-hour lifetime for applications requiring maximum reliability.

Q: Are all substitutes RoHS3 compliant? A: Yes. All listed substitutes are ROHS3 compliant and suitable for applications requiring RoHS certification.
