Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following electrical and mechanical parameters: capacitance (6800 µF), voltage rating (6.3 V), tolerance (±20%), operating temperature range (-40°C ~ 105°C), lead spacing (0.197" / 5.00 mm), case diameter (0.492" / 12.50 mm), and mounting type (through hole, radial can package).

Substitute parts are grouped into four categories:

Direct Substitutes maintain identical electrical specifications and physical dimensions, differing only in packaging format or product status. These include UHE0J682MHD (Nichicon), UHW0J682MHD (Nichicon), EEU-FR0J682L (Panasonic), and EEU-FS0J682L (Panasonic).

Upgrade Substitutes provide enhanced performance characteristics such as extended lifetime or improved ripple current handling while maintaining core electrical and mechanical compatibility. EKY-6R3ELL682MK40S and EKZN6R3ELL682MK30S fall into this category.

Similar Substitutes share identical electrical specifications but differ in physical dimensions, specifically lead spacing and case diameter. EEU-FM0J682 and EEU-FM0J682B require PCB layout verification before implementation.

Parametric Equivalents match all critical electrical and mechanical specifications with minor variations in product compliance status. KY6.3VB682M12X40LL represents this category.

Engineering Selection Recommendations

For RoHS3 Compliant Applications: Select from active-status parts with ROHS3 Compliant certification: EEU-FR0J682L, EEU-FS0J682L, EKZN6R3ELL682MK30S, or EKY-6R3ELL682MK40S. These parts meet current regulatory requirements while maintaining electrical and mechanical compatibility.

For Extended Lifetime Requirements: UHW0J682MHD, EEU-FR0J682L, and EEU-FS0J682L provide 10000 hours at 105°C, compared to the original 8000 hours. Height variations require PCB layout verification.

For Direct Dimensional Match: KY6.3VB682M12X40LL and EKY-6R3ELL682MK40S maintain the original 1.575" (40.00 mm) height. KY6.3VB682M12X40LL is RoHS non-compliant; EKY-6R3ELL682MK40S is ROHS3 Compliant.

For Compact PCB Layouts: EEU-FS0J682L (1.260" height) and EKZN6R3ELL682MK30S (1.240" height) reduce vertical footprint while maintaining core electrical specifications and RoHS3 compliance.

For Non-RoHS Applications: KY6.3VB682M12X40LL provides parametric equivalence to the original UHE0J682MHT with active product status.

For Different Lead Spacing: EEU-FM0J682 and EEU-FM0J682B require 0.295" (7.50 mm) lead spacing and 0.630" (16.00 mm) case diameter. PCB redesign is necessary for these parts.

Frequently Asked Questions (FAQ)

Q: Can UHE0J682MHD directly replace UHE0J682MHT? A: Yes. UHE0J682MHD maintains identical electrical specifications (6800 µF, 6.3 V, ±20%, 8000 Hrs @ 105°C) and physical dimensions (0.197" lead spacing, 0.492" diameter, 1.575" height). The primary difference is product status (Not For New Designs) and improved RoHS3 compliance.

Q: What is the advantage of UHW0J682MHD over the original part? A: UHW0J682MHD extends lifetime to 10000 hours at 105°C and reduces height to 1.319" (34.60 mm), enabling more compact designs. Electrical specifications remain identical. PCB layout verification is required due to height reduction.

Q: Are Panasonic EEU-FR0J682L and EEU-FS0J682L interchangeable? A: Both maintain 6800 µF, 6.3 V, ±20%, and 10000 Hrs @ 105°C specifications with 0.197" lead spacing and 0.492" diameter. They differ in height: EEU-FR0J682L is 1.457" and EEU-FS0J682L is 1.260". Select based on available PCB space.

Q: Can I use EEU-FM0J682 as a substitute? A: EEU-FM0J682 matches electrical specifications but requires different PCB footprint: 0.295" lead spacing (vs. 0.197") and 0.630" diameter (vs. 0.492"). PCB redesign is necessary.

Q: What is the difference between EEU-FM0J682 and EEU-FM0J682B? A: Both parts are electrically and dimensionally identical. EEU-FM0J682B is packaged in Tape & Box format, while EEU-FM0J682 is in Bulk packaging. Select based on procurement and assembly requirements.

Q: Is KY6.3VB682M12X40LL suitable for new designs? A: KY6.3VB682M12X40LL has active product status and maintains all original specifications including 1.575" height and 0.197" lead spacing. However, it is RoHS non-compliant. For RoHS-regulated applications, use EKY-6R3ELL682MK40S instead.

Q: Which substitute offers the best compliance profile? A: EEU-FR0J682L, EEU-FS0J682L, EKZN6R3ELL682MK30S, and EKY-6R3ELL682MK40S all carry ROHS3 Compliant status with active product status, making them suitable for current regulatory environments.
