Substitute Part Grouping Explanation

Substitution for the USV1C100MFD1TP is determined by strict equivalence in the following parameters:

Capacitance: 10 µF (exact match required)
Voltage Rating: 16 V minimum (equal or higher acceptable)
Tolerance: ±20% (matching tolerance class)
Polarization: Polar (electrolytic type)
Mounting Type: Through Hole
Package Type: Radial, Can
Operating Temperature Range: -40°C ~ 105°C minimum
Lifetime @ Temperature: 5000 Hrs @ 105°C minimum
RoHS Compliance: ROHS3 Compliant

Substitutes are classified into two categories:

Parametric Equivalent: Identical electrical specifications and physical dimensions, differing only in manufacturer or series designation.

Upgrade Substitute: Higher voltage rating or improved ripple current handling while maintaining all other critical parameters.

Engineering Selection Recommendations

UTS1C100MDD1TE (Nichicon): This substitute is the primary equivalent for the USV1C100MFD1TP. It maintains identical electrical and physical specifications while offering active product status, ensuring long-term availability and supply chain continuity. Both components are manufactured by Nichicon and comply with ROHS3 standards. This substitute is suitable for direct replacement in applications where the original part is no longer available.

35ML10MEFCT54X7 (Rubycon): This upgrade substitute provides a higher voltage rating of 35 V while maintaining the same capacitance, tolerance, temperature range, and physical dimensions. The increased voltage rating provides additional design margin for applications subject to voltage transients or overvoltage conditions. However, this part is also obsolete. Selection of this upgrade should be based on circuit requirements for enhanced voltage headroom rather than availability considerations.

Frequently Asked Questions (FAQ)

Q: Can UTS1C100MDD1TE be used as a direct replacement for USV1C100MFD1TP?

A: Yes. Both components share identical capacitance (10 µF), voltage rating (16 V), tolerance (±20%), temperature range (-40°C ~ 105°C), lifetime rating (5000 Hrs @ 105°C), and physical dimensions. The UTS series is currently active, making it the recommended substitute for obsolete USV series components.

Q: What is the difference between the main part and the upgrade substitute?

A: The 35ML10MEFCT54X7 upgrade substitute differs in voltage rating (35 V versus 16 V) and lead spacing (0.098" versus 0.059"). The higher voltage rating provides additional design margin but requires verification of PCB layout compatibility due to the increased lead spacing.

Q: Are all three components RoHS compliant?

A: Yes. The USV1C100MFD1TP, UTS1C100MDD1TE, and 35ML10MEFCT54X7 are all ROHS3 compliant and REACH unaffected.

Q: What is the significance of product status (Active vs. Obsolete)?

A: Active status indicates current manufacturing and ongoing supply availability. Obsolete status indicates the part is no longer in production. The UTS1C100MDD1TE is active and recommended for new designs and long-term system support. The 35ML10MEFCT54X7, while obsolete, may be available through inventory channels.

Q: Can the upgrade substitute be used in all applications designed for the original part?

A: The 35ML10MEFCT54X7 can be used in applications where the circuit voltage does not exceed 35 V. The higher voltage rating does not degrade performance in lower-voltage applications. However, the increased lead spacing (0.098" versus 0.059") requires PCB layout verification to ensure proper fit in the original mounting holes.
