Substitute Part Grouping Explanation

Substitution eligibility for the USV1H2R2MFD is determined by the following core parameters:

Capacitance: 2.2 µF (exact match required)
Voltage Rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Operating Temperature Range: -40°C ~ 105°C (exact match required)
Mounting Type: Through Hole (exact match required for direct PCB compatibility)
Package Type: Radial, Can (exact match required for form factor compatibility)
Polarization: Polar (exact match required)

Substitute parts are grouped into two categories:

Category 1: Direct Through-Hole Radial Substitutes – Parts maintaining identical mounting type and package configuration. These include Nichicon UKL1H2R2MDDANA and Panasonic EEU-EB series variants (EEU-EB1H2R2S, EEU-EB1H2R2SB, EEU-EB1H2R2SH).

Category 2: Surface Mount Alternative – Nichicon UUL1H2R2MCL1GS provides equivalent electrical performance in SMD configuration for designs permitting surface mount technology.

Engineering Selection Recommendations

For Direct Through-Hole Replacement (Preferred):

The Panasonic EEU-EB1H2R2S, EEU-EB1H2R2SB, and EEU-EB1H2R2SH are active-status products meeting all electrical and mechanical substitution criteria. These parts maintain 5000-hour lifetime ratings at 105°C, matching the original USV1H2R2MFD performance specification. All variants are ROHS3 compliant. Selection among EEU-EB variants depends on lead spacing requirements for PCB hole patterns: EEU-EB1H2R2S (2.00mm spacing), EEU-EB1H2R2SB (5.00mm spacing), or EEU-EB1H2R2SH (2.50mm spacing).

For Surface Mount Applications:

The Nichicon UUL1H2R2MCL1GS provides equivalent electrical performance in SMD configuration with active product status and 5000-hour lifetime rating. This option is suitable only for designs utilizing surface mount assembly processes.

Caution Regarding UKL1H2R2MDDANA:

The Nichicon UKL1H2R2MDDANA meets dimensional and electrical core parameters but carries a reduced 1000-hour lifetime rating at 105°C compared to the original 5000-hour specification. This part is suitable only for applications where reduced lifetime is acceptable.

Frequently Asked Questions (FAQ)

Q: Can I use EEU-EB1H2R2SB as a direct replacement for USV1H2R2MFD?

A: EEU-EB1H2R2SB matches all core electrical parameters (2.2 µF, 50 V, ±20%, 5000 Hrs @ 105°C) and mounting type (through-hole radial). However, the lead spacing differs: EEU-EB1H2R2SB uses 5.00mm spacing versus USV1H2R2MFD's 1.50mm spacing. PCB hole pattern compatibility must be verified before selection.

Q: What is the difference between the three Panasonic EEU-EB variants?

A: All three variants (EEU-EB1H2R2S, EEU-EB1H2R2SB, EEU-EB1H2R2SH) are electrically identical with matching capacitance, voltage, tolerance, and lifetime ratings. The primary difference is lead spacing: 2.00mm (S), 5.00mm (SB), and 2.50mm (SH). Selection is determined by PCB hole pattern requirements.

Q: Why does UKL1H2R2MDDANA have a lower lifetime rating?

A: The UKL1H2R2MDDANA is rated for 1000 hours at 105°C versus the original 5000-hour specification. This represents a different product series within Nichicon's portfolio. Use this part only when reduced lifetime is acceptable for the application.

Q: Can I use the SMD variant UUL1H2R2MCL1GS on a through-hole PCB?

A: No. The UUL1H2R2MCL1GS is designed for surface mount assembly and is not compatible with through-hole PCB designs. This option applies only to designs utilizing SMD manufacturing processes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the original USV1H2R2MFD specification.
