Substitute Part Grouping Explanation

Substitution eligibility for the 10ZLS680MEFC8X11.5 is determined by the following critical parameters:

Capacitance: 680 µF (exact match required)
Voltage - Rated: 10 V (exact match required)
Tolerance: ±20% (exact match required)
Package / Case: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.138" (4.60mm) (exact match required)
Physical Dimensions: 0.315" Dia (8.00mm), Height 0.512" (13.00mm) (exact match required)
Operating Temperature Range: -40°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)

Substitute parts must meet all critical parameters. Secondary performance parameters such as ripple current, impedance, and lifetime at temperature may vary within acceptable ranges for the application.

Engineering Selection Recommendations

10ZLH680MEFC8X11.5 (Rubycon ZLH Series): This direct manufacturer equivalent from Rubycon offers extended lifetime of 8000 hours at 105°C compared to the original 6000 hours. The part is active in production and ROHS3 compliant. Physical and electrical parameters are identical to the main part. This substitute provides improved reliability for long-term applications.

EEU-FR1A681 (Panasonic FR-A Series): This parametric equivalent from Panasonic meets all critical electrical and mechanical specifications. The part is active in production and ROHS3 compliant. Ripple current performance is higher at both 120 Hz and 100 kHz, and impedance is lower, offering improved thermal performance in high-ripple-current applications.

UHV1A681MPD (Nichicon UHV Series): This parametric equivalent from Nichicon meets all critical electrical and mechanical specifications. However, the product status is listed as "Not For New Designs," indicating this part is in mature or end-of-life phase. REACH status is affected. This substitute should be used only for legacy system maintenance or replacement applications where new design qualification is not required.

Frequently Asked Questions (FAQ)

Q: Can I substitute 10ZLH680MEFC8X11.5 for 10ZLS680MEFC8X11.5?

A: Yes. Both parts are manufactured by Rubycon and share identical capacitance (680 µF), voltage rating (10 V), tolerance (±20%), package type (radial can), mounting type (through hole), and physical dimensions. The 10ZLH680MEFC8X11.5 offers extended lifetime (8000 hours vs. 6000 hours at 105°C) and is a direct upgrade.

Q: Are Panasonic EEU-FR1A681 and Nichicon UHV1A681MPD interchangeable with the original part?

A: Both parts meet all critical electrical and mechanical parameters required for substitution. However, the Nichicon UHV1A681MPD is marked "Not For New Designs," making it suitable only for replacement or legacy applications. The Panasonic EEU-FR1A681 is recommended for new designs requiring a non-Rubycon source.

Q: What are the key parameters that must match for substitution?

A: Capacitance (680 µF), voltage rating (10 V), tolerance (±20%), package type (radial can), mounting type (through hole), lead spacing (0.138" / 4.60mm), physical dimensions (0.315" diameter, 0.512" height), operating temperature range (-40°C to 105°C), and polarization (polar) must all match exactly.

Q: Does the difference in ripple current rating affect substitution eligibility?

A: No. Ripple current is a secondary performance parameter. All listed substitutes meet the critical parameters. Higher ripple current capability (as seen in the Panasonic and Nichicon parts) represents improved performance and does not prevent substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitutes, including 10ZLH680MEFC8X11.5, EEU-FR1A681, and UHV1A681MPD, are ROHS3 compliant.
