Engineering Selection Recommendations

Primary Recommendation: EKZE630ELL820MH15D

EKZE630ELL820MH15D is the direct upgrade from Chemi-Con. It maintains identical electrical specifications (82 µF, 63 V, ±20%, 3000 Hrs @ 105°C) and mechanical compatibility (lead spacing, case diameter). The part is active in production and ROHS3 compliant. Height increases from 0.591" to 0.650", which remains within standard through-hole PCB design tolerances. This substitution requires no circuit redesign.

Secondary Recommendations: Rubycon ZLJ Series (63ZLJ82M8X11.5, 63ZLJ82MCT8X11.5, 63ZLJ82MCR8X11.5)

All three Rubycon ZLJ series parts are electrically equivalent with identical capacitance, voltage, and tolerance specifications. These parts offer extended lifetime (8000 Hrs @ 105°C versus 3000 Hrs), ROHS3 compliance, and active product status. Height is reduced to 0.512" (13.00 mm), providing space advantage in compact designs. Impedance increases to 180 mOhms. These parts are suitable for applications where extended reliability is beneficial.

Alternative: UHE1J820MPD

UHE1J820MPD from Nichicon maintains electrical and mechanical compatibility but carries "Not For New Designs" status. This part is ROHS3 compliant and offers 7000 Hrs lifetime at 105°C. However, impedance is significantly higher at 450 mOhms, which may affect ripple current performance in noise-sensitive applications. This part is suitable only for legacy system maintenance.

Frequently Asked Questions (FAQ)

Q: Can EKZE630ELL820MH15D replace KZE63VB82RM8X15LL directly?

A: Yes. Both parts share identical electrical specifications (82 µF, 63 V, ±20%, 3000 Hrs @ 105°C) and mechanical compatibility (lead spacing 0.138", case diameter 0.315", through-hole mounting). The height difference (0.650" versus 0.591") is within standard PCB design margins for radial capacitors.

Q: What is the advantage of Rubycon ZLJ series substitutes?

A: The 63ZLJ82M8X11.5, 63ZLJ82MCT8X11.5, and 63ZLJ82MCR8X11.5 maintain full electrical equivalence while offering extended lifetime (8000 Hrs @ 105°C) and reduced height (0.512"). All are ROHS3 compliant and in active production. The trade-off is slightly higher impedance (180 mOhms versus 160 mOhms).

Q: Are there differences between 63ZLJ82M8X11.5, 63ZLJ82MCT8X11.5, and 63ZLJ82MCR8X11.5?

A: All three parts are electrically and mechanically identical. Differences exist only in internal construction codes (M, MCT, MCR designations). For substitution purposes, any of these three Rubycon parts are interchangeable.

Q: Why is UHE1J820MPD marked "Not For New Designs"?

A: This designation indicates the part is in mature/declining production phase. While suitable for replacement in existing systems, it should not be selected for new product development. The part remains available and functional but may face future discontinuation.

Q: Does impedance difference affect circuit performance?

A: Impedance variation (160 mOhms to 450 mOhms) affects ripple current handling and high-frequency noise filtering. For general-purpose applications, impedance differences within this range are typically acceptable. Applications with strict ripple current or noise specifications should verify compatibility with actual circuit requirements.

Q: Are all substitute parts RoHS compliant?

A: EKZE630ELL820MH15D, all three Rubycon ZLJ series parts, and UHE1J820MPD are ROHS3 compliant. The original KZE63VB82RM8X15LL is RoHS non-compliant. Compliance status should be verified against specific product requirements.

Q: Can these parts be used in high-temperature applications?

A: All parts operate across -40°C to 105°C. Lifetime ratings at 105°C vary: KZE63VB82RM8X15LL (3000 Hrs), EKZE630ELL820MH15D (3000 Hrs), Rubycon ZLJ series (8000 Hrs), and UHE1J820MPD (7000 Hrs). Selection should match application temperature profile and required operational lifetime.
