Substitute Part Grouping Explanation

Substitution of the EEU-FC1C470B is determined by the following criteria:

Primary Matching Parameters:

Capacitance: 47 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: 16 V minimum (equal or higher voltage acceptable)
Polarization: Polar (exact match required)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)
Operating Temperature Range: -55°C to 105°C (exact match required)

Secondary Compatibility Parameters:

Lead Spacing: 0.197" (5.00 mm) preferred for direct PCB fit
Size / Dimension: 0.197" Dia (5.00 mm) preferred for mechanical fit
Height - Seated: Variations acceptable if PCB clearance permits
Ripple Current Ratings: Must meet or exceed application requirements
Impedance: Lower impedance preferred for improved performance
RoHS and AEC-Q200 compliance: Required for automotive applications

Substitute parts are grouped into two categories: upgrade parts with higher voltage ratings and equivalent parts with identical electrical specifications but different manufacturers or packaging formats.

Engineering Selection Recommendations

For Active Production Designs:

Use EEU-FC1E470B as an upgrade substitute when higher voltage margin is required. This part maintains identical mechanical dimensions, impedance, and ripple current ratings while providing 25 V rated voltage instead of 16 V. Both parts are Panasonic FC series, AEC-Q200 rated, and actively produced.

Use EEU-FC1C470 as an equivalent when packaging format changes from Cut Tape to Bulk. This part is electrically and mechanically identical to EEU-FC1C470B with the same 16 V rating, impedance, and ripple current specifications. Lead spacing differs (0.079" vs 0.197"), requiring PCB layout verification.

Use ELXZ160ELL470MEB5D (Chemi-Con LXZ series) as an equivalent when extended lifetime is beneficial. This part matches all critical parameters with improved impedance (500 mOhms vs 800 mOhms) and doubled lifetime (2000 Hrs vs 1000 Hrs at 105°C). AEC-Q200 compliance is maintained. Lead spacing differs, requiring PCB layout verification.

For Legacy or Constrained Designs:

UPM1C470MDD (Nichicon UPM series) is acceptable as an equivalent substitute. This part maintains AEC-Q200 compliance, identical impedance (800 mOhms), and automotive application rating. Product status is obsolete; availability may be limited. Lead spacing differs (0.079" vs 0.197"), requiring PCB layout verification.

Not Recommended:

UPV1C470MFD, UPJ1C470MDD, and UPS1C470MDD are obsolete parts without AEC-Q200 compliance. These parts lack automotive certification and are not suitable for new automotive designs. Use only if legacy system maintenance requires exact part matching and no alternatives are available.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC1E470B replace EEU-FC1C470B directly?

A: Yes. EEU-FC1E470B is a direct mechanical and electrical upgrade. The 25 V rating accommodates circuits designed for 16 V operation with increased voltage margin. Identical dimensions, impedance, and ripple current ratings ensure drop-in compatibility.

Q: What is the difference between EEU-FC1C470B and EEU-FC1C470?

A: Both parts are electrically identical (47 µF, 16 V, ±20%, 1000 Hrs @ 105°C). The primary difference is packaging: EEU-FC1C470B is supplied in Cut Tape format, while EEU-FC1C470 is supplied in Bulk. Lead spacing differs (0.197" vs 0.079"), requiring PCB layout verification before substitution.

Q: Why does ELXZ160ELL470MEB5D have lower ripple current at 120 Hz?

A: ELXZ160ELL470MEB5D is a Chemi-Con LXZ series part with different internal construction optimized for extended lifetime (2000 Hrs vs 1000 Hrs). Lower ripple current at low frequency reflects different thermal and electrical characteristics. High-frequency ripple current (175 mA @ 100 kHz) matches the original part.

Q: Are obsolete parts acceptable substitutes?

A: Obsolete parts (UPV1C470MFD, UPJ1C470MDD, UPS1C470MDD) lack AEC-Q200 automotive certification and are not recommended for new designs. Use only for legacy system maintenance when no active alternatives are available and exact part matching is required.

Q: What PCB layout changes are required when using parts with different lead spacing?

A: Parts with 0.079" lead spacing (EEU-FC1C470, ELXZ160ELL470MEB5D, UPJ1C470MDD, UPM1C470MDD, UPS1C470MDD) require PCB footprint modification compared to the original 0.197" spacing. Verify PCB hole diameter, pad size, and trace routing compatibility before assembly.

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

A: UPV1C470MFD offers the longest rated lifetime (5000 Hrs @ 105°C) but lacks AEC-Q200 compliance and is obsolete. For active production, ELXZ160ELL470MEB5D provides doubled lifetime (2000 Hrs vs 1000 Hrs) while maintaining AEC-Q200 compliance and active availability.

Q: Can I use a higher voltage rated capacitor in place of the 16 V part?

A: Yes. Higher voltage ratings (such as EEU-FC1E470B at 25 V) are acceptable substitutes. The capacitor will operate safely at lower voltages than its rating. Verify that physical dimensions and lead spacing accommodate PCB layout requirements.
