Substitute Part Grouping Explanation

Substitution for the UPV1H2R2MFD is determined by strict equivalence across the following parameters:

Electrical Parameters: Capacitance (2.2 µF), voltage rating (50 V), and tolerance (±20%) must match exactly
Physical Parameters: Package type (radial, can), lead spacing (0.079" / 2.00 mm), and diameter (0.197" / 5.00 mm) must be compatible with the PCB layout
Environmental Parameters: Operating temperature range (-55°C to 105°C) and polarization (polar) must be maintained
Compliance: RoHS3 compliance is required for regulatory alignment

Substitute parts are grouped into two categories based on availability and product status:

Category 1 - Nichicon Series (Obsolete): UPJ1H2R2MDD, UPM1H2R2MDD, UPW1H2R2MDD. These parts share identical electrical and core physical specifications with the main part. Differences exist in lifetime ratings (2000 Hrs @ 105°C vs. 5000 Hrs) and impedance characteristics, which do not affect basic substitution compatibility.

Category 2 - Panasonic FC Series (Active): EEU-FC1H2R2, EEU-FC1H2R2H, EEU-FC1H2R2B. These parts maintain electrical equivalence and are currently in active production. Lead spacing variations exist (0.079" to 0.098" to 0.197") and height differences (0.472" to 0.571"), requiring PCB layout verification.

Engineering Selection Recommendations

For General-Purpose Applications with Extended Lifetime Requirements: The UPJ1H2R2MDD and UPW1H2R2MDD offer direct Nichicon substitutes with identical lead spacing (0.079" / 2.00 mm) and compatible height profiles. These parts maintain full PCB compatibility while providing active inventory availability. The UPJ1H2R2MDD is preferred for applications where the reduced lifetime (2000 Hrs vs. 5000 Hrs) is acceptable, while UPW1H2R2MDD offers improved impedance characteristics (3 Ohms) for high-frequency filtering applications.

For Automotive Applications with Active Production Status: The Panasonic EEU-FC1H2R2 and EEU-FC1H2R2H are recommended for new designs requiring AEC-Q200 certification. Both parts are in active production with substantial inventory availability. The EEU-FC1H2R2 maintains the original lead spacing (0.079" / 2.00 mm) and is the preferred direct substitute. The EEU-FC1H2R2H offers a slightly wider lead spacing (0.098" / 2.50 mm) for applications where PCB layout permits this variation.

For Space-Constrained Designs: The UPW1H2R2MDD provides the lowest profile height (0.433" / 11.00 mm) among all substitutes while maintaining lead spacing compatibility, making it suitable for compact PCB layouts.

For High-Frequency Applications: The Panasonic FC series (EEU-FC1H2R2, EEU-FC1H2R2H) and UPW1H2R2MDD offer significantly lower impedance (1.8 Ohms and 3 Ohms respectively) compared to the original part (7 Ohms), improving performance in high-frequency filtering and decoupling circuits.

Avoid for New Designs: EEU-FC1H2R2B is not recommended as a primary substitute due to its significantly increased height (0.571" / 14.50 mm) and wider lead spacing (0.197" / 5.00 mm), which may require substantial PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can I use EEU-FC1H2R2H as a direct replacement for UPV1H2R2MFD without PCB modification?

A: The EEU-FC1H2R2H maintains electrical equivalence and is mechanically compatible with the original part. However, the lead spacing differs (0.098" vs. 0.079"), requiring verification that the PCB pad layout accommodates this 0.019" (0.50 mm) difference. Height compatibility (0.472" vs. 0.492") is acceptable for most applications.

Q: What is the impact of impedance differences between substitute parts?

A: Impedance affects high-frequency performance and ripple current handling. Lower impedance (1.8 Ohms in Panasonic FC series) provides superior performance in high-frequency filtering and decoupling applications. Higher impedance (7 Ohms in the original UPV1H2R2MFD) is acceptable for low-frequency filtering and general-purpose energy storage. Selection depends on circuit frequency requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, maintaining regulatory alignment with the original UPV1H2R2MFD.

Q: Which substitute offers the best long-term availability?

A: The Panasonic EEU-FC1H2R2 and EEU-FC1H2R2H are in active production status with substantial inventory levels (4,099 and 18,861 units respectively), providing superior long-term availability compared to obsolete Nichicon alternatives.

Q: Can I use UPM1H2R2MDD in automotive applications?

A: Yes. The UPM1H2R2MDD carries AEC-Q200 certification and is suitable for automotive applications. However, it is classified as obsolete, making it less suitable for new automotive designs. The active Panasonic FC series is preferred for new automotive applications.

Q: What is the significance of the 5000 Hrs vs. 1000 Hrs lifetime difference?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C). The original UPV1H2R2MFD (5000 Hrs) offers extended service life compared to Panasonic FC series (1000 Hrs). For applications operating continuously at elevated temperatures, the longer lifetime may be critical. For typical room-temperature operation, this difference has minimal practical impact.

Q: Is lead spacing critical for substitution?

A: Yes. Lead spacing determines PCB pad compatibility. The original part uses 0.079" (2.00 mm) spacing. Substitutes with identical spacing (UPJ1H2R2MDD, UPM1H2R2MDD, UPW1H2R2MDD, EEU-FC1H2R2) are direct mechanical replacements. Wider spacing variants (EEU-FC1H2R2H at 0.098", EEU-FC1H2R2B at 0.197") require PCB layout verification before substitution.
