Engineering Selection Recommendations

Direct Equivalent (Same Lifetime Performance):

The 108CKE063M from Cornell Dubilier / Illinois Capacitor provides direct electrical equivalence with identical 2000-hour lifetime at 105°C. This part is suitable for applications where the ESH108M063AM2AA is unavailable and extended lifetime is not required. The 108CKE063M offers a more compact height (1.043" vs. 1.339"), which may be advantageous in space-constrained designs.

Enhanced Lifetime Substitutes (Active Production):

The ESL108M063AM9AA (KEMET), EKZN630ELL102ML25S (Chemi-Con), MAL215058102E3, and MAL215068102E3 (Vishay) all provide 10000-hour lifetime at 105°C, representing a five-fold improvement over the original part. These are suitable for applications requiring extended operational reliability. The ESL108M063AM9AA maintains KEMET series continuity and is the preferred upgrade within the same manufacturer family.

Extended Temperature Performance:

The EGXE630ELL102MLN3S (Chemi-Con) extends the upper operating temperature to 125°C with 5000-hour lifetime and includes AEC-Q200 automotive certification. This part is appropriate for automotive applications or environments with elevated ambient temperatures.

High-Temperature Automotive Grade:

The UBW1J102MHD (Nichicon) provides the highest temperature capability at 135°C maximum operating temperature with 3000-hour lifetime at that temperature. This part includes AEC-Q200 certification and is rated for automotive applications. The extended lower temperature limit (-55°C) provides broader environmental coverage.

Discontinued Status Consideration:

The UPS1J102MHD (Nichicon) carries a "Not For New Designs" status and should not be selected for new product development, though it remains electrically compatible for legacy system maintenance.

Frequently Asked Questions (FAQ)

Q: Can I substitute the ESH108M063AM2AA with any of the listed parts?

A: Yes. All listed parts maintain the critical electrical parameters (1000 µF, 63 V, ±20% tolerance) and mechanical compatibility (lead spacing, case diameter, through-hole mounting). Physical height variations exist but do not affect electrical function. Verify that the substitute part's height accommodates your PCB layout constraints.

Q: What is the primary difference between the ESH108M063AM2AA and ESL108M063AM9AA?

A: Both are KEMET radial aluminum electrolytic capacitors with identical electrical ratings. The ESL series provides 10000-hour lifetime at 105°C compared to 2000 hours for the ESH series. The ESL108M063AM9AA is physically more compact (1.260" height vs. 1.339"). The ESL is the recommended upgrade path within the KEMET product family.

Q: Are any of these parts suitable for automotive applications?

A: Yes. The EGXE630ELL102MLN3S, MAL215058102E3, MAL215068102E3, and UBW1J102MHD all carry AEC-Q200 automotive certification. These parts are appropriate for automotive-grade designs. The UBW1J102MHD offers the highest temperature rating (135°C) among automotive-qualified options.

Q: What does "Not For New Designs" mean for the UPS1J102MHD?

A: This designation indicates that Nichicon has discontinued this part for new product development. While the part remains electrically compatible and is available in inventory, it should not be selected for new designs. Use UBW1J102MHD as the current Nichicon alternative.

Q: How do I choose between the extended-lifetime options?

A: Selection depends on application requirements and environmental conditions. For general-purpose applications at standard temperatures, the ESL108M063AM9AA or EKZN630ELL102ML25S provide 10000-hour lifetime at 105°C. For automotive applications or elevated-temperature environments, select EGXE630ELL102MLN3S (125°C) or UBW1J102MHD (135°C). For cost-sensitive applications where 2000-hour lifetime is acceptable, the 108CKE063M provides equivalent performance in a more compact package.

Q: Will the physical height difference affect my circuit board design?

A: Possibly. The ESH108M063AM2AA has a maximum seated height of 1.339" (34.00 mm). Substitute parts range from 1.043" to 1.319" in height. Shorter substitutes (108CKE063M, EKZN630ELL102ML25S at 1.043") provide additional clearance. Taller substitutes (EGXE630ELL102MLN3S, MAL215058102E3, MAL215068102E3, UBW1J102MHD, UPS1J102MHD at 1.319") fit within the original envelope. Verify your specific PCB layout requirements before selection.

Q: Are all these parts RoHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant. The UBW1J102MHD is REACH Affected; all other parts are REACH Unaffected. Verify REACH compliance requirements for your specific application and supply chain.

Q: What is the difference between ESR and Impedance specifications?

A: ESR (Equivalent Series Resistance) and Impedance are related but distinct parameters. ESR is typically measured at specific frequencies (e.g., 100 kHz or 120 Hz). Impedance represents the total opposition to current flow at a given frequency. The ESH108M063AM2AA does not specify ESR; substitute parts provide impedance values ranging from 24 mOhms to 59 mOhms. Lower impedance values indicate better high-frequency performance and lower ripple current effects.
