Substitute Part Grouping Explanation

Substitution eligibility for the UPM1K331MHD6 is determined by the following core parameters:

Electrical Specifications: Capacitance (330 µF), voltage rating (80 V), and tolerance (±20%) must match exactly
Thermal Performance: Lifetime rating of 5000 Hrs @ 105°C and operating temperature range (-55°C ~ 105°C) must be maintained
Physical Compatibility: Lead spacing (0.295" / 7.50mm), diameter (0.630" / 16.00mm), and height must accommodate PCB layout constraints
Polarization: Polar configuration is required
Mounting: Through-hole radial, can package only

Substitute parts are grouped into three categories:

Direct Substitutes (identical electrical and mechanical specifications, packaging variation only): UPJ1K331MHD6TN differs only in packaging format (Cut Tape vs. Bulk).

Similar Substitutes (same electrical specifications, minor mechanical variations): UPJ1K331MHD and UPM1K331MHD share identical electrical ratings but feature different lead spacing (0.197" / 5.00mm) and physical dimensions, requiring PCB redesign verification.

Upgrade Substitute (enhanced performance, same electrical base): ELXV800ELL331ML25S from Chemi-Con offers improved impedance characteristics and active product status while maintaining core electrical specifications.

Engineering Selection Recommendations

For Direct PCB Compatibility (No Layout Changes Required):

UPJ1K331MHD6TN and ELXV800ELL331ML25S are the primary candidates. Both maintain identical lead spacing (0.295" / 7.50mm), diameter (0.630" / 16.00mm), and height specifications within acceptable tolerance. UPJ1K331MHD6TN is a Nichicon part with matching series characteristics but lacks AEC-Q200 certification. ELXV800ELL331ML25S from Chemi-Con carries AEC-Q200 automotive rating and active product status, making it suitable for new production support of legacy automotive applications.

For Automotive Applications with Compliance Requirements:

UPM1K331MHD and ELXV800ELL331ML25S both carry AEC-Q200 certification. UPM1K331MHD is a Nichicon part within the same UPM series as the original but requires PCB redesign due to different lead spacing (0.197" / 5.00mm). ELXV800ELL331ML25S maintains original footprint compatibility while offering active product status and lower impedance (81 mOhms vs. 99 mOhms).

For General Purpose Applications Without Automotive Constraints:

UPJ1K331MHD and UPJ1K331MHD6TN are suitable alternatives. Both are Nichicon UPJ series parts with identical electrical specifications. UPJ1K331MHD6TN in Cut Tape packaging is preferred for automated assembly; UPJ1K331MHD in Bulk packaging is suitable for manual assembly or rework operations.

Frequently Asked Questions (FAQ)

Q: Can UPJ1K331MHD be used as a direct replacement for UPM1K331MHD6 without PCB modification?

A: No. While electrical specifications are identical, UPJ1K331MHD has different lead spacing (0.197" / 5.00mm vs. 0.295" / 7.50mm) and physical dimensions. PCB redesign is required.

Q: What is the difference between UPJ1K331MHD6TN and UPJ1K331MHD?

A: Both are Nichicon UPJ series 330 µF, 80 V capacitors with identical electrical specifications. The primary difference is packaging: UPJ1K331MHD6TN is supplied in Cut Tape format for automated pick-and-place assembly, while UPJ1K331MHD is supplied in Bulk format. Minor variations exist in ripple current ratings and impedance due to manufacturing tolerances.

Q: Why is ELXV800ELL331ML25S listed as an upgrade substitute?

A: ELXV800ELL331ML25S maintains all core electrical specifications (330 µF, 80 V, ±20%, 5000 Hrs @ 105°C) while offering three advantages: active product status (vs. "Not For New Designs"), lower impedance (81 mOhms vs. 99 mOhms), and AEC-Q200 automotive certification. It maintains original footprint compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: Which substitute part is recommended for automotive applications requiring AEC-Q200 certification?

A: ELXV800ELL331ML25S is the primary recommendation. It carries AEC-Q200 certification, maintains original lead spacing and physical dimensions, and offers active product status. UPM1K331MHD is an alternative but requires PCB redesign due to different lead spacing.

Q: Can UPM1K331MHD6 be replaced with a part having different lead spacing?

A: Substitution with different lead spacing (such as UPJ1K331MHD or UPM1K331MHD) requires PCB layout verification and potential redesign. Direct footprint compatibility cannot be assumed without engineering review of the specific application circuit.
