Substitute Part Grouping Explanation

The UEP1V101MPD1TD qualifies as a direct substitute based on the following criteria:

• Identical Capacitance: Both parts are rated at 100 µF, meeting the primary electrical requirement
• Identical Tolerance: Both maintain ±20% tolerance specification
• Identical Mechanical Form Factor: Lead spacing (5.00mm), package diameter (10.00mm), and seated height (17.50mm) are identical, ensuring PCB compatibility without layout modification
• Identical Thermal Characteristics: Both operate across -55°C ~ 105°C with 2000 Hrs @ 105°C lifetime rating
• Identical Mounting Configuration: Both are through-hole radial components in the same package class
• Identical Compliance: Both are ROHS3 Compliant and REACH Unaffected

The substitute part features a higher voltage rating (35 V vs. 10 V), which represents an upgrade path for applications where voltage margin improvement is beneficial without electrical or mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The UEP1V101MPD1TD is a qualified substitute for the UEP1A331MPD1TD in applications requiring 100 µF capacitance with radial through-hole mounting. Both components maintain identical mechanical compatibility and thermal performance specifications. The substitute part's elevated voltage rating (35 V) provides additional design margin without introducing incompatibility with the original 10 V specification, as the substitute will operate safely in circuits designed for the lower voltage.

Both parts carry identical compliance certifications (ROHS3 Compliant, REACH Unaffected), ensuring regulatory alignment for existing designs. The substitute part's Not For New Designs status aligns with the original component, indicating both are legacy products within the Nichicon UEP series.

Frequently Asked Questions (FAQ)

Q: Can the UEP1V101MPD1TD be used as a direct replacement for the UEP1A331MPD1TD?

A: Yes. The substitute part maintains identical capacitance (100 µF), tolerance (±20%), mechanical dimensions, lead spacing, and thermal characteristics. PCB layout modification is not required.

Q: What is the primary difference between these two parts?

A: The substitute part is rated for 35 V versus the original 10 V rating. This represents a voltage upgrade and does not affect compatibility in 10 V applications.

Q: Are there any mounting or footprint differences?

A: No. Both parts are through-hole radial components with identical lead spacing (5.00mm), package diameter (10.00mm), and seated height (17.50mm).

Q: Do both parts meet the same compliance requirements?

A: Yes. Both are ROHS3 Compliant and REACH Unaffected, maintaining identical regulatory status.

Q: What is the ripple current difference between these parts?

A: The original part supports 240 mA @ 120 Hz and 360 mA @ 10 kHz. The substitute part supports 160 mA @ 120 Hz and 240 mA @ 10 kHz. Applications requiring higher ripple current should retain the original part specification.
