UPJ1J680MPD Equivalent & Substitute Parts

Part Overview

The UPJ1J680MPD is a 68 µF, 63 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as "Not For New Designs," indicating it has been superseded in the product lifecycle. The part operates across a temperature range of -55°C to 105°C with a rated lifetime of 3000 hours at 105°C, suitable for general-purpose applications requiring polar capacitive filtering and energy storage.

Identifying equivalent and substitute parts is necessary due to the product's discontinued status for new designs, supply chain considerations, and potential performance improvements available in active alternatives.

Engineering Selection Recommendations

For Direct Replacement (Same Form Factor, 0.138" Lead Spacing):

UPW1J680MPD (Nichicon, Active) is the primary recommendation. It maintains identical electrical specifications and lead spacing as the UPJ1J680MPD while holding active product status. This part eliminates obsolescence risk without requiring PCB redesign.

For Automotive Applications with Enhanced Reliability:

ELXZ630ELL680MH12D, ELXY630ELL680MH15D, or ELXV630ELL680MH15D (Chemi-Con, Active, AEC-Q200) are suitable for designs requiring automotive-grade qualification. These parts maintain the 0.138" lead spacing and 3000-hour lifetime while providing AEC-Q200 compliance.

EEU-FC1J680BJ (Panasonic, Active, AEC-Q200) offers automotive qualification with identical electrical performance and 0.138" lead spacing.

For Extended Lifetime Requirements (5000 Hours @ 105°C):

UPJ1J680MPD6 or UPM1J680MPD6 (Nichicon) provide 5000-hour lifetime ratings. UPM1J680MPD6 includes AEC-Q200 certification. Both require 0.197" lead spacing accommodation.

ELXY630ELL680MJ16S (Chemi-Con, Active, AEC-Q200) delivers 5000-hour lifetime with automotive qualification and 0.197" lead spacing.

For Lowest Impedance (Superior High-Frequency Performance):

ELXY630ELL680MJ16S (210 mOhms) and UPM1J680MPD6 (190 mOhms) provide the lowest impedance values, beneficial for applications with high ripple current or stringent transient response requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different lead spacing?

A: Lead spacing changes require PCB layout verification. The UPJ1J680MPD uses 0.138" (4.60mm) spacing. Substitutes with 0.197" (5.00mm) spacing (UPJ1J680MPD6, UPM1J680MPD6, EEU-FC1J680B, ELXY630ELL680MJ16S) require confirmation that the PCB footprint accommodates the wider spacing. Mechanical fit must be validated before implementation.

Q: What is the difference between Nichicon UPJ, UPM, and UPW series?

A: All three series meet the 68 µF, 63 V specification. UPJ and UPM are discontinued for new designs. UPW is active. UPM includes AEC-Q200 automotive certification. Series selection depends on product status requirements and application environment.

Q: Are Panasonic EEU-FC and Chemi-Con ELX series direct equivalents?

A: Electrically, yes—all maintain 68 µF, 63 V, ±20% tolerance, and polar configuration. Mechanically, lead spacing and height vary by specific part number suffix. Panasonic EEU-FC series carries 2000-hour lifetime ratings, while Chemi-Con ELX series offers 3000 or 5000-hour options. Both manufacturers provide AEC-Q200 variants for automotive use.

Q: Why do some substitutes have lower lifetime ratings (2000 Hrs vs. 3000 Hrs)?

A: Lifetime rating reflects the capacitor's expected operational duration at maximum rated temperature (105°C). Lower lifetime ratings do not indicate inferior quality but rather different design specifications. Application requirements determine acceptable lifetime minimums. General-purpose applications may tolerate 2000-hour ratings; reliability-critical designs should specify 3000 hours or greater.

Q: Can I substitute a part with lower impedance?

A: Lower impedance (measured in mOhms) indicates better high-frequency performance and reduced voltage ripple. Substituting with lower-impedance parts (e.g., ELXY630ELL680MJ16S at 210 mOhms vs. original 260 mOhms) improves circuit performance without compatibility issues, provided electrical and mechanical parameters remain within specification.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive-grade qualification standard. Parts bearing this rating have undergone stress testing and reliability validation for automotive environments. Use AEC-Q200 parts only when automotive qualification is a design requirement; general-purpose applications do not require this certification.

Q: Are all listed substitutes RoHS3 compliant?

A: Yes. All parts in this reference list carry ROHS3 Compliant status, meeting lead-free and hazardous substance restrictions for EU and global markets.
