Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UPJ1K331MHD6 is determined by strict equivalence across the following critical parameters:

• Electrical Parameters: Capacitance (330 µF), voltage rating (80 V), and tolerance (±20%) must match exactly
• Thermal Specifications: Lifetime rating (5000 Hrs @ 105°C) and operating temperature range (-55°C ~ 105°C) must be maintained
• Mechanical Compatibility: Lead spacing (0.295" / 7.50mm), case diameter (0.630" / 16.00mm), and height (1.043" / 26.50mm) must accommodate PCB layout constraints
• Package Configuration: Radial, can package with through-hole mounting is required for direct substitution

Substitute parts are categorized as follows:

Direct Substitutes (identical packaging and lead spacing): UPJ1K331MHD6TN, UPM1K331MHD6, ELXV800ELL331ML25S

Similar Substitutes (equivalent electrical and thermal performance, different lead spacing or case dimensions): UPJ1K331MHD, UPM1K331MHD

Parameter Comparison

Engineering Selection Recommendations

For Direct Mechanical and Electrical Substitution:

UPJ1K331MHD6TN is the closest equivalent, differing only in packaging format (Cut Tape versus Bulk). This part maintains identical electrical specifications, thermal ratings, and physical dimensions. Selection is appropriate when tape packaging is acceptable for assembly processes.

UPM1K331MHD6 provides direct mechanical compatibility with identical lead spacing and case dimensions. This part carries AEC-Q200 automotive qualification, which may be beneficial for applications requiring automotive-grade reliability, though the main part does not specify this requirement.

For Active Product Status:

ELXV800ELL331ML25S (Chemi-Con LXV series) is the only substitute with Active product status, indicating current manufacturing and long-term availability. This part maintains identical mechanical dimensions and electrical specifications. The lower impedance (81 mOhms versus 99 mOhms) represents improved high-frequency performance characteristics. This part is suitable for new designs and long-term production requirements.

For Alternative Lead Spacing:

UPJ1K331MHD and UPM1K331MHD offer equivalent electrical and thermal performance but feature different mechanical configurations (0.197" lead spacing, smaller case diameter, increased height). These parts are suitable only when PCB layout accommodates the modified footprint.

Frequently Asked Questions (FAQ)

Q: Can UPJ1K331MHD6TN be used as a direct replacement for UPJ1K331MHD6?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: UPJ1K331MHD6TN is supplied in cut tape, while UPJ1K331MHD6 is supplied in bulk. Selection depends on assembly process requirements.

Q: What is the difference between UPJ and UPM series capacitors?

A: The UPM series carries AEC-Q200 automotive qualification and is rated for automotive applications. The UPJ series is general-purpose. Both maintain identical electrical specifications (330 µF, 80 V, ±20%, 5000 Hrs @ 105°C) but differ in application classification and ripple current ratings.

Q: Can I use UPJ1K331MHD instead of UPJ1K331MHD6?

A: Electrical substitution is possible, but mechanical compatibility must be verified. UPJ1K331MHD has different lead spacing (0.197" versus 0.295"), smaller case diameter (0.492" versus 0.630"), and greater height (1.457" versus 1.043"). PCB layout must accommodate these dimensional changes.

Q: Why is ELXV800ELL331ML25S recommended for new designs?

A: ELXV800ELL331ML25S is the only substitute with Active product status, ensuring current manufacturing and long-term availability. It maintains identical mechanical dimensions and electrical specifications as the original part while offering improved impedance characteristics (81 mOhms).

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant, matching the compliance status of the original UPJ1K331MHD6.

Q: What is the significance of impedance differences among substitutes?

A: Impedance values (ranging from 81 to 99 mOhms) reflect internal resistance characteristics. Lower impedance generally indicates better high-frequency performance. For general-purpose applications at standard operating frequencies, these differences are not functionally significant.
