Substitute Part Grouping Explanation

Substitution eligibility is determined by strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

Capacitance: 68 µF (exact match required)
Voltage Rating: 100 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

Secondary Considerations:

Operating Temperature Range: -55°C ~ 105°C (exact match required)
RoHS Compliance: ROHS3 Compliant (required for regulatory alignment)

Substitute parts are grouped into two categories:

Direct Substitutes maintain identical physical dimensions (0.394" diameter, 1.063" height) and electrical performance specifications, including ripple current ratings and impedance characteristics.

Similar Substitutes share all critical electrical parameters but differ in physical dimensions (larger case diameter or reduced height) or thermal lifetime ratings (3000 Hrs vs. 5000 Hrs @ 105°C). These parts are mechanically compatible with the through-hole footprint but require PCB layout verification for clearance.

Engineering Selection Recommendations

Direct Substitutes (Identical Footprint & Performance):

UPM2A680MPD1TD and UPJ2A680MPD1TD are direct electrical and mechanical equivalents. Both maintain the 0.394" diameter and 1.063" height envelope. UPM2A680MPD1TD preserves AEC-Q200 automotive qualification and identical ripple current specifications. UPJ2A680MPD1TD offers equivalent electrical performance but lacks automotive rating and exhibits reduced ripple current capacity (326 mA @ 120 Hz vs. 500 mA). Selection between these depends on automotive compliance requirements.

Panasonic EEU-FC2A680LB (Active Product Status):

EEU-FC2A680LB is the only active-status substitute with matching physical dimensions (0.394" diameter, 1.063" height) and identical impedance (210 mOhms). It carries AEC-Q200 certification and supports automotive applications. The thermal lifetime is reduced to 3000 hours at 105°C compared to the UPM2A680MPD specification of 5000 hours. This part is suitable for applications where extended thermal life is not a critical design parameter.

Larger Case Alternatives (Reduced Height):

UPJ2A680MHD6, UPM2A680MHD6, EEU-FC2A680, EEU-FC2A680B, and EEU-FC2A680Y feature enlarged case diameter (0.492" vs. 0.394") with reduced height (0.630" to 0.669" vs. 1.063"). These parts are mechanically compatible with the through-hole footprint but require PCB layout verification to confirm clearance around the larger diameter. All maintain 5000-hour thermal ratings and AEC-Q200 certification (except UPJ2A680MHD6).

Compact Alternative (Reduced Height):

UPW2A680MPD offers the smallest height profile (0.787") while maintaining the 0.394" diameter. Impedance is elevated to 300 mOhms, and ripple current capacity is reduced to 318.5 mA @ 120 Hz. This part lacks automotive rating and is designated for general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute UPM2A680MPD with a part having different capacitance or voltage rating?

A: No. Substitution requires exact matching of capacitance (68 µF) and voltage rating (100 V). Deviations compromise circuit performance and reliability.

Q: What is the difference between Direct and Similar substitutes?

A: Direct substitutes maintain identical physical dimensions and electrical performance. Similar substitutes share electrical specifications but differ in case size or thermal lifetime. Similar substitutes require PCB layout verification for mechanical clearance.

Q: Is EEU-FC2A680LB suitable for automotive applications?

A: Yes. EEU-FC2A680LB carries AEC-Q200 certification and is rated for automotive use. However, the thermal lifetime is 3000 hours at 105°C versus the original part's 5000 hours. Verify thermal requirements for your specific application.

Q: Why do some substitutes have larger case diameters?

A: Larger case diameters (0.492" vs. 0.394") allow for improved thermal dissipation and reduced impedance in some designs. These parts are mechanically compatible with the through-hole footprint but require confirmation that PCB layout accommodates the increased diameter.

Q: What does "Not For New Designs" mean?

A: This designation indicates the part is obsolete or in end-of-life status. Active-status alternatives such as the Panasonic EEU-FC series are recommended for new designs while maintaining electrical and mechanical compatibility with legacy systems.

Q: Can I use a substitute with reduced ripple current rating?

A: Substitution is valid only if the application's ripple current requirement does not exceed the substitute part's rating. Verify ripple current specifications at both 120 Hz and 10 kHz / 100 kHz to ensure adequate margin.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Bulk, Cut Tape, Tape & Box) does not affect electrical or thermal performance. Selection is based on procurement and assembly requirements.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitutes are ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions.
