UHE1C392MHT Equivalent & Substitute Parts

Part Overview

The UHE1C392MHT is a 3900 µF, 16 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 10,000 hours at 105°C, suitable for general-purpose applications requiring stable capacitance and ripple current handling.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters: capacitance value (3900 µF), voltage rating (16 V), tolerance (±20%), polarization (polar), package type (radial can), and mounting type (through hole). Physical dimensions including lead spacing, diameter, and height must remain compatible with the PCB layout. Ripple current ratings and impedance values are provided for performance verification but do not restrict substitution eligibility when all primary parameters match.

Substitute parts are grouped into three categories:

Similar Nichicon UHE Series: Parts UHE1C392MHD, UHE1C392MHD3, and UHE1C392MHD6 share identical electrical specifications with the main part but differ in packaging designation, product status, and physical dimensions. These variants maintain the same capacitance, voltage, and tolerance but feature different lead spacing and height configurations.

Direct Equivalents (Active Status): Parts from Rubycon (16ZLJ3900M12.5X35, 16ZLJ3900MCC12.5X35), Panasonic (EEU-FR1C392L, EEU-FS1C392L), and Chemi-Con (EKZN160ELL392MK35S) match all primary electrical and mechanical parameters with active product status and RoHS3 compliance.

Upgrade Option: EKY-160ELL392MK40S from Chemi-Con provides equivalent electrical performance with enhanced specifications and active product status.

Similar Alternative: EEU-FM1C392 from Panasonic maintains matching capacitance, voltage, and tolerance but specifies 7,000 hours lifetime at 105°C instead of 10,000 hours, with different physical dimensions.

Engineering Selection Recommendations

For new designs and ongoing production, select from parts with active product status and RoHS3 compliance. The Rubycon 16ZLJ3900M12.5X35 and 16ZLJ3900MCC12.5X35, Panasonic EEU-FR1C392L, and Chemi-Con EKZN160ELL392MK35S provide direct mechanical and electrical equivalence to the UHE1C392MHT with identical lead spacing (0.197"), diameter (0.492"), and 10,000-hour lifetime specifications.

For applications where PCB layout permits height variation, the Panasonic EEU-FS1C392L offers a more compact 1.260" height while maintaining all electrical parameters. The Chemi-Con EKY-160ELL392MK40S provides equivalent performance with a taller profile (1.634") suitable for applications with vertical clearance.

The Panasonic EEU-FM1C392 is suitable only for applications where the reduced 7,000-hour lifetime at 105°C is acceptable and where the larger lead spacing (0.295") and different physical dimensions (0.630" diameter, 1.063" height) are compatible with the PCB footprint.

Nichicon UHE1C392MHD variants are not recommended for new designs due to their "Not For New Designs" status, though they remain available for legacy system maintenance where exact form factor matching is required.

Frequently Asked Questions (FAQ)

Q: Can UHE1C392MHD be used as a direct replacement for UHE1C392MHT?

A: UHE1C392MHD shares identical electrical specifications and physical dimensions with UHE1C392MHT. However, UHE1C392MHD carries a "Not For New Designs" status and is not recommended for new applications. It remains suitable for legacy system repairs where exact part matching is necessary.

Q: What is the primary difference between the Rubycon 16ZLJ3900M12.5X35 and 16ZLJ3900MCC12.5X35?

A: Both parts are electrically and mechanically identical with matching capacitance, voltage, tolerance, lifetime, and physical dimensions. The difference lies in internal construction or manufacturing process, indicated by the different suffix codes. Both are active products with RoHS3 compliance.

Q: Can EEU-FM1C392 replace UHE1C392MHT in all applications?

A: EEU-FM1C392 matches the capacitance, voltage, and tolerance specifications but differs in three critical aspects: reduced lifetime (7,000 hours versus 10,000 hours at 105°C), larger lead spacing (0.295" versus 0.197"), and different physical dimensions. Substitution is only valid if the PCB footprint accommodates the larger spacing and if the reduced lifetime meets application requirements.

Q: Which substitute part has the smallest physical footprint?

A: The Panasonic EEU-FS1C392L has the smallest height at 1.260" while maintaining the standard 0.197" lead spacing and 0.492" diameter. All other direct equivalents with matching lead spacing range from 1.437" to 1.634" in height.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed carry RoHS3 compliance except the original UHE1C392MHT, which is RoHS non-compliant. The Nichicon UHE1C392MHD variants are RoHS3 compliant.

Q: What is the impedance difference between substitute parts?

A: Impedance values range from 12 mOhms (EEU-FR1C392L) to 26 mOhms (UHE1C392MHD3). Lower impedance indicates better high-frequency performance. For general-purpose applications, impedance differences within this range do not restrict substitution eligibility when all primary electrical parameters match.

Q: Can parts with different lead spacing be used interchangeably?

A: No. Lead spacing determines PCB hole positioning and cannot be changed without redesigning the circuit board. Parts with 0.197" lead spacing are not interchangeable with parts having 0.295" lead spacing. Verify PCB footprint compatibility before selection.
