Substitute Part Grouping Explanation

Substitute parts for the USV1H4R7MFD are qualified based on the following electrical and mechanical parameters:

Capacitance: 4.7 µF (exact match required)
Voltage Rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime @ Temperature: 5000 Hrs @ 105°C (exact match required)
Operating Temperature Range: -40°C ~ 105°C (exact match required)
Polarization: Polar (exact match required)
Package Type: Radial, Can (exact match required)
Size / Dimension: 0.197" Dia (5.00mm) (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)

Substitutes are grouped into two categories: through-hole radial can packages (direct mechanical and electrical equivalents) and surface-mount variants (electrical equivalents with different mounting technology).

Engineering Selection Recommendations

Through-Hole Radial Can Substitutes (Direct Mechanical Equivalents):

The Panasonic EEU-EB series parts (EEU-EB1H4R7S, EEU-EB1H4R7SB, EEU-EB1H4R7SH) are active product status alternatives that meet all electrical specifications of the USV1H4R7MFD. These parts are ROHS3 compliant and suitable for direct board-level replacement in through-hole applications. Height variations (0.472" vs. 0.315") must be evaluated for PCB layout clearance.

The Nichicon UHE1H4R7MDD is an obsolete Nichicon alternative with identical electrical specifications but increased height (0.492"). This part is suitable where vertical clearance permits.

Surface-Mount Alternative:

The Nichicon UUL1H4R7MCL1GS is an active product surface-mount variant with identical electrical specifications. This part is appropriate for designs utilizing surface-mount assembly processes and offers reduced height (0.240"). Mounting technology differs from through-hole applications.

Compliance Basis:

All substitute parts carry ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the original part. Selection should prioritize active product status parts (Panasonic EEU-EB series) for long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the Panasonic EEU-EB series directly replace the Nichicon USV1H4R7MFD?

A: Yes. The EEU-EB1H4R7S, EEU-EB1H4R7SB, and EEU-EB1H4R7SH parts match all electrical parameters (4.7 µF, 50 V, ±20%, 5000 Hrs @ 105°C) and package type (radial, can, through-hole). PCB layout must accommodate the increased height of 0.472" compared to the original 0.315".

Q: What is the difference between EEU-EB1H4R7S, EEU-EB1H4R7SB, and EEU-EB1H4R7SH?

A: These parts are electrically identical. The differences are in packaging format: EEU-EB1H4R7S is supplied in bulk, EEU-EB1H4R7SB in cut tape, and EEU-EB1H4R7SH in cut tape with different lead spacing (0.098" vs. 0.079"). Lead spacing affects PCB pad layout compatibility.

Q: Is the surface-mount UUL1H4R7MCL1GS suitable for through-hole applications?

A: No. The UUL1H4R7MCL1GS is designed for surface-mount assembly and requires different PCB land patterns and soldering processes. It is electrically equivalent but mechanically incompatible with through-hole designs.

Q: Why is the USV1H4R7MFD marked as obsolete?

A: Obsolete status indicates the part is no longer manufactured. Active alternatives such as the Panasonic EEU-EB series provide equivalent electrical and mechanical performance for new designs and production continuity.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original USV1H4R7MFD.
