Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: capacitance (330 µF), voltage rating (100 V), tolerance (±20%), impedance (70 mOhms), lead spacing (0.295" / 7.50mm), package type (Radial, Can), and mounting type (Through Hole). All identified substitutes maintain these core electrical and mechanical specifications.

The substitute parts are categorized as follows:

Direct Manufacturer Equivalents (Nichicon Series): Parts UPM2A331MHD6 and UPJ2A331MHD6 share identical electrical parameters with the main part. Differences exist in packaging format (Bulk vs. Cut Tape) and application classification (Automotive vs. General Purpose).

Parametric Equivalent (Nichicon UPJ Series): Part UPJ2A331MHD6TN matches all core parameters and packaging format (Cut Tape) but is classified for General Purpose applications rather than Automotive.

Cross-Manufacturer Equivalent (Panasonic): Part EEU-FC2A331SB from Panasonic Electronic Components maintains all critical electrical and mechanical parameters, with AEC-Q200 automotive rating and Active product status.

Engineering Selection Recommendations

For Automotive Applications with AEC-Q200 Requirement: EEU-FC2A331SB is the preferred substitute. This Panasonic component maintains Active product status, carries AEC-Q200 automotive certification, and meets all electrical and mechanical specifications of the main part. This option is suitable for new design qualification and ongoing production.

For Direct Nichicon Series Continuity: UPM2A331MHD6 provides identical electrical performance and automotive rating to the main part, with the distinction of Bulk packaging. This option is appropriate when packaging format flexibility exists.

For General Purpose Applications: UPJ2A331MHD6TN and UPJ2A331MHD6 are suitable alternatives when automotive certification is not required. Both maintain all core electrical parameters and mechanical compatibility, with UPJ2A331MHD6TN offering Cut Tape packaging matching the main part format.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC2A331SB be used as a direct replacement for UPM2A331MHD6TN in automotive applications?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (100 V), tolerance (±20%), impedance (70 mOhms), lead spacing (7.50mm), and package configuration (Radial, Can, Through Hole). Both carry AEC-Q200 certification. The primary distinction is manufacturer (Panasonic vs. Nichicon) and product status (Active vs. Not For New Designs).

Q: What is the difference between UPM2A331MHD6TN and UPM2A331MHD6?

A: These parts are electrically and mechanically identical. The difference is packaging format: UPM2A331MHD6TN is supplied in Cut Tape (CT), while UPM2A331MHD6 is supplied in Bulk. Both are Nichicon UPM series with automotive rating and AEC-Q200 compliance.

Q: Are UPJ series parts suitable for automotive applications?

A: UPJ2A331MHD6TN and UPJ2A331MHD6 are classified for General Purpose applications and do not carry AEC-Q200 certification. While they meet all electrical and mechanical parameters of the main part, they are not recommended for applications requiring automotive qualification.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates the main part (UPM2A331MHD6TN) is in end-of-life phase. EEU-FC2A331SB, with Active product status, is the recommended choice for new design implementations. Existing designs may continue using any electrically equivalent substitute based on application requirements.

Q: Do all substitute parts have identical ripple current ratings?

A: No. Ripple current specifications vary between manufacturers and series. UPM series parts specify 1.26 A @ 120 Hz and 1.65 A @ 10 kHz. UPJ series parts specify 1.08 A @ 120 Hz and 1.42 A @ 10 kHz. EEU-FC2A331SB specifies 923 mA @ 120 Hz and 1.42 A @ 100 kHz. Application-specific ripple current requirements must be verified against the selected substitute.

Q: Is height variation between parts significant?

A: UPJ2A331MHD6 has a maximum seated height of 1.043" (26.50mm), while all other substitutes specify 1.063" (27.00mm). This 0.5mm difference is negligible for most through-hole applications but should be verified for space-constrained PCB layouts.
